、90°回転されると流路な全開にする。(4) Action: The main valve body closes the flow path, and the sub valve body closes the communication hole. (When the input shaft is rotated from the fully closed state, the teeth of the drive gear member for the sub valve body meshing with the driven gear member of When the shaft is rotated, the meshing of the sub-valve gear system ends, and the teeth of the drive gear member for the main valve body of the main valve gear system begin to mesh with the driven gear member for the main valve body. The main valve shaft is rotated, and the main valve body opens the flow path, and when rotated 90 degrees, the flow path is fully opened.
このとき、相対的ζ=副弁体は連通孔を閉鎖する。これ
によって主弁体が流路を全開し、かつ副弁体が連通孔を
閉鎖した全開状態となる。At this time, the relative ζ=auxiliary valve body closes the communication hole. As a result, the main valve body fully opens the flow path and the sub valve body closes the communication hole, resulting in a fully open state.

全閉状態となる。Next, to achieve a fully closed state, the input shaft is rotated in the opposite direction. As a result, the main valve element completely closes the flow path, and the subsequent valve element closes the communication hole, reverting to the original fully closed state.

When closing, the main valve body can be fully closed after the main valve body is fully closed. Therefore, it is possible to prevent erroneous operations such as the water hammer phenomenon occurring due to the wrong closing order of the main valve body and the sub-valve body ( Two can be prevented.

おける圧力上昇を防止することができる。In addition, since the main valve body can be fully closed, the sub-valve body can be fully opened, so when the water flow rate is low at the time of installation in the pipeline, the water flow rate can be adjusted by simply opening and closing the sub-valve body. This makes it possible to prevent a pressure increase in the downstream pipeline.

となると、相対的に連通孔lOを閉鎖することとなる。When the input shaft 23 is rotated in the opening direction by the operating handle 51 from this fully closed state, the auxiliary valve shaft 1 is rotated by the meshing of the driven gear 18 with the teeth 30 of the driving gear 26 of the auxiliary valve gear system. The sub-valve body 13 opens the communication hole 0 of the main valve body 8, and the teeth 30 of the drive gear 26 and the driven gear 18
When the engagement is completed, the sub-valve body 13 is rotated by 9G',
As shown in FIG. 5, ζ: The communication hole IO is fully opened. At this time, the relationship between the main and auxiliary valve gear systems and the locking parts of the main and auxiliary valve systems is as shown in FIGS. 6A to 6D. When the process is completed, the drive gear 2 of the main valve body gear system is moved as shown in Fig. 6D.
5 and the driven gear] 4 starts to match. Therefore, when the input shaft 23 is rotated in the opening direction two times in a row, the main valve shaft 6 is rotated due to the meshing of the teeth 29 of the drive gear 25 of the main valve body gear system and the driven gear 14, and thereby the main valve body 8 is rotated. When the flow path 7 is opened and the engagement between the teeth 29 of the driving gear 25 and the driven gear 14 approaches the end, the main valve body 8 is rotated by 90 degrees as shown in FIG. The second flow path 7 is fully opened. At this time, the relationship between the main and auxiliary valve body gear systems and the locking parts of the main and auxiliary valve systems is as shown in FIGS. 8A to 8D. Since there is no mesh between the teeth 29 of the drive gear 25 of the gear system and the driven gear 14, the sub-valve shaft 11 is not rotated, and therefore the sub-valve body 13 maintains its position, so that the main valve body 8 is rotated as described above. When it reaches the fully open position, the communication hole IO is relatively closed.

噛合が開始している。Next, in order to change the state from the fully open state shown in FIG. The lid now rotates in the closing direction, which is the opposite direction. When the input shaft 23 rotates, the main valve shaft 6 is rotated by the engagement between the teeth 29 of the drive gear 25 of the main valve body gear system and the driven gear 14, and as a result, the main valve body 8 first closes the flow path 7. When the flow path 7 is rotated by 90 degrees,
fully closed. In this state, the meshing between the teeth 29 of the drive gear 25 of the main valve gear system and the driven gear 4 is completed, and the meshing between the teeth 30 of the drive gear 26 of the universal valve gear system and the driven gear 18 is completed. It has started.

勢によってガタつくのを防止する。As described above, from fully closed to fully open, the communication hole 1o is fully opened by the sub-valve body 13, and then the flow path 7 leading to the main valve body 8 is fully opened, and from fully open to fully closed, the main valve body After the flow path 7 is completely closed by the sub-valve body 8, the communication hole 10 is fully closed by the sub-valve body 3, thereby preventing the water hammer phenomenon caused by the sudden closing of the main valve body 8. In addition, when the main valve body 8 and the sub-valve body 13 are opened, when the main valve body 8 is opened, the locking protrusion 3 of the sub-valve body
5 is locked with the locking recess 38, and when the sub-valve body 13 is opened, the locking protrusion 34 of the main valve system is locked with the locking recess 37,
The sub-valve body 13 and the main valve body 8, which are not opened, are prevented from rattling due to the flow of fluid.
