Description
本発明は、管トラップを備えた排水配管に関し、特に吸気弁が取り付けられる排水配管に関する。 The present invention relates to a drain pipe provided with a pipe trap, and particularly to a drain pipe to which an intake valve is attached.
排水配管には、排水の逆流防止や下水からの臭気の遮断を目的として、排水トラップが備えられている。管体をＵ字状に屈曲させた排水トラップは、屈曲させた部分に排水が溜まり、管体が水封されることにより、臭気や害虫類の逆流を防止するようになっている。 The drainage pipe is provided with a drainage trap for the purpose of preventing backflow of drainage and blocking odor from sewage. The drain trap with the tubular body bent in a U-shape is configured to prevent odor and pests from flowing back by collecting drainage at the bent portion and sealing the tubular body.
この排水トラップには、排水の勢いが強いと下流側がサイフォン効果によって負圧になり、トラップ内の封水が失われてしまうという問題がある。そのため、封水の下流側の配管近傍に吸気弁を設けて、負圧が発生しても吸気弁から吸気することで負圧を除去し、封水が失われないようにすることが提案されている（例えば、特許文献１参照。）。 This drain trap has a problem that if the drainage force is strong, the downstream side becomes negative pressure due to the siphon effect, and the sealed water in the trap is lost. Therefore, it has been proposed to provide an intake valve in the vicinity of the pipe on the downstream side of the sealed water so that even if a negative pressure is generated, the negative pressure is removed by suctioning from the intake valve so that the sealed water is not lost. (For example, refer to Patent Document 1).
しかしながら、排水の流路と吸気弁の位置が近いと、吸気弁側に排水の飛沫が飛散して、吸気弁に当たって音を発生させたり、また、弁に排水が触れて弁の劣化を招いたりするという問題がある。 However, if the drainage flow path and the intake valve are close to each other, splashes of drainage will be scattered on the intake valve side, causing noise when hitting the intake valve, or causing the valve to deteriorate due to the drainage touching the valve. There is a problem of doing.
また、上記特許文献１の装置では、歯科用器具に取り付けられる排水配管のようにトラップ配管の封水の下流側を鉛直方向にしない等、配管の制約がある場合には適用できない。 Moreover, the apparatus of the above-mentioned Patent Document 1 cannot be applied when there is a restriction on the piping, such as a case where the downstream side of the sealing water of the trap pipe is not in the vertical direction, such as a drain pipe attached to a dental instrument.
そこで、本発明は、上記課題に鑑みなされたものであり、配管スペースに制約が課せられ、流路と吸気弁とが近接している場合でも、排水の飛沫が吸気弁にかかることがないトラップ配管を提供することを目的とする。 Therefore, the present invention has been made in view of the above problems, and a trap is provided in which restrictions are imposed on the piping space, and even when the flow path and the intake valve are close to each other, splashes of drainage are not applied to the intake valve. The purpose is to provide piping.
上記の課題を解決するため、本発明に係るトラップ配管は、管トラップと管トラップにおける破封を防止するための吸気弁とを備えたトラップ配管であって、前記管トラップの下流側の配管本体の上側に、前記吸気弁を接続するための枝管部分を設け、前記枝管部分と前記配管本体との接続部分の径が、前記吸気弁と前記枝管部分との接続部分の径よりも細くされていることを特徴とする。これによれば、配管本管の上側に吸気弁との接続部分が設けられており、枝管部分と配管本管との接続部分の径が細くされているので、流路と吸気弁とが近接していても吸気弁に排水の飛沫が飛び込みにくくすることができる。 In order to solve the above-described problem, a trap pipe according to the present invention is a trap pipe including a pipe trap and an intake valve for preventing breakage in the pipe trap, and a pipe main body on the downstream side of the pipe trap A branch pipe part for connecting the intake valve is provided on the upper side of the pipe, and a diameter of a connection part between the branch pipe part and the pipe body is larger than a diameter of a connection part between the intake valve and the branch pipe part. It is characterized by being thinned. According to this, the connection part with the intake valve is provided on the upper side of the pipe main pipe, and the diameter of the connection part between the branch pipe part and the pipe main pipe is narrowed. Even if they are close to each other, it is possible to make it difficult for water splash to jump into the intake valve.
また、前記枝管部分は、前記管トラップと前記配管本体との接続部分近傍に設けられるとするのが好ましく、これによれば配管レイアウトの自由度をもたせることが可能となる。 Further, the branch pipe portion is preferably provided in the vicinity of the connection portion between the pipe trap and the pipe main body, and according to this, it is possible to provide a degree of freedom in pipe layout.
さらに、前記枝管部分を、前記配管本体と前記枝管部分との接続部分の径に対し、排水の上流側に偏心させているのが好ましく、前記枝管部分近傍の配管本体の管内に、排水の向きに沿って突出して前記枝管部分の径を縮める管内凸部が形成されているのがより好ましい。 Furthermore, it is preferable that the branch pipe part is eccentric to the upstream side of the drainage with respect to the diameter of the connection part between the pipe main body and the branch pipe part, and in the pipe of the pipe main body in the vicinity of the branch pipe part, It is more preferable that an in-tube convex portion that protrudes along the direction of drainage to reduce the diameter of the branch pipe portion is formed.
これによれば、吸気弁との接続部分の開口面積を狭くして、その接続部分が排水の下流側で開口されることにより、吸気弁への排水飛沫の飛散を防止でき、かつ、吸気弁が配管の上方へ突き出されることもなく、配管スペースに制約が課せられる箇所にも対応可能なトラップ配管が実現される。 According to this, the opening area of the connection portion with the intake valve is narrowed, and the connection portion is opened on the downstream side of the drainage, so that the splashing of drainage water to the intake valve can be prevented, and the intake valve Is not protruded above the pipe, and a trap pipe that can cope with places where restrictions are imposed on the pipe space is realized.
このように、本発明に係るトラップ配管によれば、配管本管の上側に吸気弁との接続部分を設けることで、吸気弁に排水の飛沫が飛び込むことを防止することができる。また、配管本体と枝管部分との接続部分に、排水の向きに沿って突出して枝管部分の径を縮める管内凸部を形成することで、さらに吸気弁へ排水の飛沫を飛び込ませないようにすることができ、吸気弁を配管の上方へ突き出させないコンパクトな配管構成にすることができる。 As described above, according to the trap pipe according to the present invention, by providing the connection portion with the intake valve on the upper side of the pipe main pipe, it is possible to prevent the splash of waste water from jumping into the intake valve. In addition, by forming an in-pipe convex part that projects along the direction of drainage to reduce the diameter of the branch pipe part at the connection part between the pipe body and the branch pipe part, it prevents further splashing of drainage into the intake valve. Thus, a compact piping configuration in which the intake valve does not protrude above the piping can be obtained.
以下、本発明に係るトラップ配管について図を参照しながら説明する。 Hereinafter, the trap pipe according to the present invention will be described with reference to the drawings.
図１は、トラップ配管の構成を示す図である。 FIG. 1 is a diagram showing the configuration of the trap pipe.
本実施の形態に係るトラップ配管は、管トラップを備えた排水配管であり、管体をＵ字状に屈曲させた排水トラップ１と、接続継手２と、吸気弁３とを備えている。 The trap pipe according to the present embodiment is a drain pipe provided with a pipe trap, and includes a drain trap 1, a pipe body bent in a U-shape, a connection joint 2, and an intake valve 3.
排水トラップ１の上流側には、図示していない排水器本体に接続するための排水器接続部４が備えられ、排水トラップ１の下流側には接続継手２と接続するための継手接続部５が備えられている。 A drainage connector 4 for connecting to a drainage body not shown is provided on the upstream side of the drain trap 1, and a joint connection 5 for connecting to the connection joint 2 on the downstream side of the drain trap 1. Is provided.
接続継手２は、排水トラップ１の下流に位置する配管であり、サイフォン効果による破封を防止する吸気弁３を取り付けるための枝管である吸気弁接続部６を備えている。吸気弁接続部６は、水平に配置された接続継手２の本管の上側に設けられているので、吸気弁３側に排水の飛沫が飛び込みにくくなっている。ここで、接続継手２は、配管の施工時に管をカットすることにより長さの調整を行うようになっている。そのため、配管レイアウトの自由度をもたせる観点から、吸気弁接続部６は、排水トラップ１に近い接続継手２の上流側（継手接続部５の近傍）に配置するのが好ましい。 The connection joint 2 is a pipe located downstream of the drain trap 1 and includes an intake valve connection portion 6 that is a branch pipe for attaching the intake valve 3 that prevents breakage due to the siphon effect. Since the intake valve connecting portion 6 is provided on the upper side of the main pipe of the connecting joint 2 that is horizontally disposed, it is difficult for the splash of waste water to jump into the intake valve 3 side. Here, the length of the connection joint 2 is adjusted by cutting the pipe during the construction of the pipe. Therefore, from the viewpoint of providing a degree of freedom in piping layout, the intake valve connection portion 6 is preferably disposed on the upstream side of the connection joint 2 close to the drain trap 1 (in the vicinity of the joint connection portion 5).
図２は、吸気弁接続部６近傍の構成を拡大して示す図である。 FIG. 2 is an enlarged view showing the configuration in the vicinity of the intake valve connecting portion 6.
吸気弁接続部６の近傍の接続継手２には、接続継手２の本管へ食い込むように管内凸部７が形成されており、接続継手２と吸気弁接続部６との接続部分の径である枝管接続部径８の開口面積を狭くして、吸気弁３と接続継手２との接続部分の通水・通気面積が、吸気弁接続部６および接続継手２の本管のそれよりも細くなるようにしている。管内凸部７は、排水の向きに沿って突出しており、排水の下流側で枝管接続部径８が開口されることになるので、吸気弁３へ排水の飛沫が飛びにくくすることを可能にしている。また、管内凸部７を接続継手２の本管内へ食い込むように形成することで、吸気弁３をなるべく配管の上方へ突き出ないようコンパクトな構成にすることができるので、配管スペースに制約が課せられる状況下においても対応が可能となる。ここで、吸気弁３と接続継手２との接続部分となる吸気弁接続部６を、枝管接続部径８に対して排水の上流側へ偏心させれば、つまり、吸気弁接続部６を枝管接続部径８に対して排水の上流側へずらすことで、より排水の飛沫が吸気弁３へ飛散することを防止することもできる。 The connecting joint 2 in the vicinity of the intake valve connecting portion 6 is formed with an in-pipe convex portion 7 so as to bite into the main pipe of the connecting joint 2, and the diameter of the connecting portion between the connecting joint 2 and the intake valve connecting portion 6 is The opening area of a certain branch pipe connection part diameter 8 is narrowed so that the water passage / ventilation area of the connection part between the intake valve 3 and the connection joint 2 is larger than that of the main pipe of the intake valve connection part 6 and the connection joint 2. I try to make it thinner. The in-pipe convex portion 7 protrudes along the direction of the drainage, and the branch pipe connection portion diameter 8 is opened on the downstream side of the drainage. Therefore, it is possible to make it difficult for the splash of the drainage to fly to the intake valve 3. I have to. In addition, by forming the in-pipe convex portion 7 so as to bite into the main pipe of the connection joint 2, the intake valve 3 can be made compact so as not to protrude above the pipe as much as possible. It is possible to respond even under certain circumstances. Here, if the intake valve connection portion 6 that is a connection portion between the intake valve 3 and the connection joint 2 is eccentric to the upstream side of the drainage with respect to the branch pipe connection portion diameter 8, that is, the intake valve connection portion 6 is By shifting to the upstream side of the drainage with respect to the branch pipe connection part diameter 8, it is possible to prevent the splashes of the drainage from scattering to the intake valve 3 more.
このように、本実施の形態に係るトラップ配管によれば、吸気弁３と接続継手２との接続部分となる吸気弁接続部６が接続継手２の本管の上側に設けられているので、吸気弁３へ排水の飛沫が飛び込むことを防止することができる。また、接続継手２の本管へ食い込むように排水の向きに沿って突出する管内凸部７が形成されているので、枝管接続部径８の開口面積を狭くするとともに、吸気弁接続部６と接続継手２との接続部分が排水の下流側で開口されることになり、吸気弁３へ排水の飛沫はさらに飛びにくくなっている。 Thus, according to the trap pipe according to the present embodiment, the intake valve connection portion 6 that is the connection portion between the intake valve 3 and the connection joint 2 is provided on the upper side of the main pipe of the connection joint 2. It is possible to prevent the splash of waste water from jumping into the intake valve 3. Moreover, since the pipe | tube convex part 7 which protrudes along the direction of drainage so that it may bite into the main pipe of the connection joint 2 is formed, while opening the branch pipe connection part diameter 8, the intake valve connection part 6 is narrowed. Therefore, the connection portion between the connection joint 2 and the connection joint 2 is opened on the downstream side of the waste water, and the splash of the waste water is more difficult to fly to the intake valve 3.
以上、本発明に係るトラップ配管について、実施形態に基づいて説明したが本発明はこれに限定されるものではなく、本発明の目的を達成でき、かつ発明の要旨を逸脱しない範囲内で種々設計変更が可能であり、それらも全て本発明の範囲内に包含されるものである。 The trap pipe according to the present invention has been described above based on the embodiment. However, the present invention is not limited to this, and various designs can be made within the scope of the present invention without departing from the gist of the present invention. Modifications are possible and all fall within the scope of the present invention.
例えば、上記実施の形態では、水平に配置された接続継手の本管の上側に吸気弁接続部を設ける例を説明したが、トラップの下流側の配管の上側に吸気弁接続部を設ける構成であれば、配管が水平に配置されていなくてもよい。 For example, in the above-described embodiment, the example in which the intake valve connection portion is provided on the upper side of the main pipe of the connection joint arranged horizontally has been described. However, the intake valve connection portion is provided on the upper side of the pipe on the downstream side of the trap. If there is, the piping does not have to be arranged horizontally.
