Furthermore, it has two built-in valve bodies, one of which adjusts the mixing ratio of the cross-sectional area of two of the three channels, and the other valve to fully open the remaining one. Or a fully closed function,
Alternatively, by sharing the function of adjusting an arbitrary opening degree from fully open to fully closed, a new three-way valve having a high degree of adjustment function is provided.

１図は混合型、第２図は分割型の例である。 Three-way valves are used to mutually adjust the flow paths on three sides, and there are two types: a mixed type and a split type. Figures 1 and 2 are typical examples of conventional three-way valves. That is, FIG. 1 shows an example of a mixed type, and FIG. 2 shows an example of a divided type.
第１図において、弁棒３を上下動させることに

断面積比に応じて流出側Ｃ，Ｄへ分配される。 In FIG. 2, as the valve stem 8 moves up and down, the position of the plug 10 moves, and the cross-sectional area ratio of the flow path to the outflow side pipe changes, and the fluid on the inflow side CD flows out according to the cross-sectional area ratio. It is distributed to sides C and D.
これら従来型三方弁は、流量比の調節はできる

である。 Although these conventional three-way valves can adjust the flow rate ratio, they are structurally incomplete in their closing function, and are generally used with a separate stop valve connected in series.
本発明は、従来型三方弁のこうした欠点を解消

Alternatively, the opening can be adjusted arbitrarily, and the other valve body can arbitrarily adjust the opening of one of the two flow passage cross-sectional areas from fully closed to fully open, and at the same time adjust the opening of the other flow passage cross-sectional area from fully open to fully open. The opening can be adjusted as desired when closed, and furthermore, the valve body in the above is a so-called ball-shaped valve body that rotates with the valve stem and has a spherical surface, and the valve seat facing it is made of metal. , made of hard material such as ceramics. The valve body is a hemispherical ball valve body that is free within a certain angle relative to the rotation of the valve stem, and the valve seat that faces the valve body is made of a soft material such as rubber or PTFE.

でよい。 Next, examples of the present invention will be described. Figures 3 to 5
The figure shows one embodiment of the invention. That is, in these figures, the valve box 11 is a T-shaped casing having three flow passages. Inside this valve box 11, there is one valve stem 12, a valve body 14, and a valve body 1.
7 is included. The valve stem 12 is connected to a valve body 14 via a valve body yoke 13, and as the valve stem 12 rotates, the valve body 14 rotates. Another valve body 17 is connected to the valve stem 12 via a boss 16, and the valve body is formed at a constant angle (for example, approximately 90 degrees in FIGS. 3 to 5) relative to the rotation of the valve stem 12. be free within the scope of However, when the valve stem 12 is further rotated beyond a certain angle, one end of the valve body 14 hits the valve body 17, so that as the valve stem 12 rotates in a certain direction, the valve body 14 and the valve body 17 rotate together. . Next, in FIGS. 3 to 5, 3 of the valve box 11
Each of the two flow paths is opened and closed by a valve body 14 or a valve body 17. A valve seat 15, a valve seat 18, and a valve seat 1 are provided at each portion where the valve bodies of these three flow paths face each other.
9 will be provided. By appropriately combining the valve seats 15, 18, and 19 with soft materials such as Teflon or rubber and hard materials such as metal, properties suitable for various uses can be imparted. It is also one of the features of the present invention that it can be carried out. That is, the valve seat 15 and the valve seat 19 are made of a hard material such as metal, and the valve seat 18 is made of a soft material such as Teflon. 17
The valve seat 18 and the valve seat 18 can be made to be in strong contact with each other. In this case, the valve body 14 rotates slightly as the valve stem 12 rotates, and the cross-sectional area ratio of the upstream pipes E and F in FIG. 3 can be adjusted as desired. However, at this time, it is assumed that the valve body 17 is in an open state with respect to the downstream pipe line EF. When it is desired to close the pipe, the valve stem 12 is rotated counterclockwise as shown in FIG. 3, and even if the valve body 14 contacts the valve body 17, if the valve stem 12 is rotated further, the valve body 14 pushes the valve body 17 around. Eventually, the relative positions shown in FIG. 5 can be achieved. In this case, the valve body 17 closes the downstream conduit EF. To return from this state to the state shown in FIG. 3, it is only necessary to turn the valve stem 12 clockwise.
第３図は混合型の例として説明したが、EF側
を上流側として逆に流せば分割型としても使うこ
とができる。 Although Fig. 3 has been explained as an example of a mixed type, it can also be used as a split type by setting the EF side as the upstream side and flowing in the opposite direction.
第５図においては、Ｌ字型の管路で弁体１４
が弁座１５側の管路断面積を変えることが可能
であり、Ｌ字型の二方調節弁として使える。 In FIG. 5, the valve body 14 is connected to an L-shaped conduit.
It is possible to change the cross-sectional area of the pipe on the valve seat 15 side, and it can be used as an L-shaped two-way control valve.
次に、弁座１５と弁座１８を硬質材で弁座
１９を軟質材の組合せで構成した場合には弁体
１７を回転して弁座１９の管路を閉止し、弁
座１５と弁座１８の管路を流れる流体を弁体
１４で調節できる。 Next, when the valve seat 15 and the valve seat 18 are made of a hard material and the valve seat 19 is made of a soft material, the valve body 17 is rotated to close the pipeline of the valve seat 19, and the valve seat 15 and the valve seat 19 are made of a soft material. The fluid flowing through the conduit in the seat 18 can be adjusted by the valve body 14.
以上の説明で、弁体を流量調節用として弁体
を開閉用として使う例を説明したが実際にはこ
の逆の使い方も可能である。 In the above explanation, an example was explained in which the valve body is used for flow rate adjustment and for opening and closing, but in reality, the reverse usage is also possible.
本発明は以上のようであるから、一個の弁で混
合と分割の両方の用途に使え、しかも優れた閉止
機能をもあわせもつコンパクトで信頼性の高い三
方弁を得ることができる。 Since the present invention is as described above, it is possible to obtain a compact and highly reliable three-way valve that can be used for both mixing and dividing purposes with a single valve, and also has an excellent closing function.
