Description

本発明は、樹脂製バルブユニットに関する。
また、本発明は、例えば給水配管等に使用される弁体等に使用される樹脂製バルブユニットに関するものである。 The present invention relates to a resin valve unit .
The present invention also relates to a resin valve unit used for a valve body used for, for example, a water supply pipe.

更にまた、本発明は、流体の流路を備える樹脂材製のハウジングと、この流路を閉じる樹脂材製の蓋部材との間隙をゴム状弾性材製のガスケットにより密封する樹脂製バルブユニットに関する。 Furthermore, the present invention relates to a resin valve unit that seals a gap between a resin material housing having a fluid flow path and a resin material lid member that closes the flow path by a rubber elastic material gasket. .

従来、特許文献１に示すような組立体が知られている。
この種組立体は、ハウジングに設けネジ穴に、蓋部材に設けた孔を介して、固定用ボルトを螺合して固定していた。
このため、部品点数が多く成るばかりでなく、ネジ溝の加工及び組立に多くの工数を要する問題を惹起した。 Conventionally, an assembly as shown in Patent Document 1 is known.
This kind of assembly is fixed by screwing a fixing bolt into a screw hole provided in the housing through a hole provided in the lid member.
For this reason, not only the number of parts increases, but the problem which requires many man-hours for processing and an assembly of a screw groove was caused.

そこで、図６に示す様に、ハウジング１００の流路１１０の端部に設けたネジ溝１１１に、蓋部材２００の外周面に設けたネジ溝２０１を螺合することにより、ハウジング１００を蓋部材２００に直接固定する方法が提案された。
しかし、部品点数は減らせるが、依然として、ネジ溝の加工及び組立に多くの工数を要する問題は解消出来なかった。
また新たに、ハウジング１００と蓋部材２００との間隙を液密に保持する為のゴム状弾性材製ガスケット３００が組み付けの際に、ネジ溝１１１により損傷を受ける危険性を招来した。 Therefore, as shown in FIG. 6, the screw groove 201 provided on the outer peripheral surface of the lid member 200 is screwed into the screw groove 111 provided on the end portion of the flow path 110 of the housing 100, whereby the housing 100 is attached to the lid member 200. A method of directly fixing to 200 has been proposed.
However, although the number of parts can be reduced, the problem that requires a large number of man-hours for machining and assembling of the screw groove still cannot be solved.
In addition, there has been a risk that the screw groove 111 may be damaged when the rubber-like elastic gasket 300 for keeping the gap between the housing 100 and the lid member 200 fluid-tight is assembled.

また、４本のボス１２、１２、１２、１２の先端部は、先の実施の態様と同様に、ステーキングされている。 The gaskets 3, 3, 3 made of rubber-like elastic material are provided between the first step portion 27 provided on the lid member 2 and the outer peripheral surface 28 of the housing 1, and on the second step provided on the lid member 2. A total of three are used between the portion 29 and the inner peripheral surface 13 of the housing 1 and on the outer peripheral surface of the valve body 4.
Moreover, the front-end | tip part of the four boss | hubs 12, 12, 12, 12 is staking similarly to the aspect of previous embodiment.

ついで、本発明に係る樹脂組立体の製造方法について説明する。
まず、図３に示す様に、流体の流路１１を備える樹脂材製のハウジング１と、流路１１を閉じるための樹脂材製の蓋部材２との間隙にゴム状弾性材製ガスケット３を配置すると共に、ハウジング１に設けた複数のボス１２、１２を、蓋部材２側に設けた複数の貫通孔２）、２２に挿通する。 Subsequently, the manufacturing method of the resin assembly which concerns on this invention is demonstrated.
First, as shown in FIG. 3, a rubber-like elastic gasket 3 is provided in a gap between a resin-made housing 1 having a fluid flow path 11 and a resin-made lid member 2 for closing the flow path 11. The plurality of bosses 12, 12 provided in the housing 1 are inserted into the plurality of through holes 2), 22 provided on the lid member 2 side.

ついで、ボス１２、１２の先端をステーキングすることにより、図２に示す様に、ハウジング１に蓋部材２を、液密に一体化するものである。
また、ボス１２、１２の先端は、超音波によりステーキングすることが望ましい。
このことにより、組立時間（カシメ時間）が通常１秒以下で行えると共に、強度が強く、複数のカシメを同時に行える。
更に、外観がきれいで、省スペース設計が容易に行える。
結果として、短時間に組立が出来ると共に、ハウジング１と蓋部材２との間隙を液密に保持する為のゴム状弾性材製ガスケット３が、組み付けの際に、ネジ溝により損傷を受ける危険性が無い。 Next, by staking the tips of the bosses 12 and 12, as shown in FIG. 2, the lid member 2 is integrated into the housing 1 in a liquid-tight manner.
Moreover, it is desirable to staking the front-end | tip of the boss | hubs 12 and 12 by an ultrasonic wave.
As a result, the assembly time (caulking time) can be normally reduced to 1 second or less, and the strength is high, and a plurality of caulking can be performed simultaneously.
Furthermore, the appearance is beautiful and space-saving design can be easily performed.
As a result, there is a risk that the rubber-made elastic gasket 3 that can be assembled in a short time and that keeps the gap between the housing 1 and the lid member 2 fluid-tight will be damaged by the screw groove during assembly. There is no.

また、本発明は上述の発明を実施するための最良の形態に限らず本発明の要旨を逸脱することなくその他種々の構成を採り得ることはもちろんである。 Further, the present invention is not limited to the best mode for carrying out the invention described above, and various other configurations can be adopted without departing from the gist of the present invention.
