段の一例である固定ナツトである。(Embodiment) This will be explained in detail below based on the illustrated embodiment. 1 is a water passage for a water heater, etc., 2 is a constant flow water governor installed in the water passage 1, a valve body 3, It consists of a pressure receiving plate 4, a governor spring 5, and a cylindrical main body 6 that accommodates them. The main body 6 has a valve chamber 7 on the upstream side that accommodates the valve body 3 and a secondary pressure chamber 8 on the downstream side into which the pressure receiving plate 4 can be slidably inserted, and both chambers 7 and 8 are formed with a valve hole 9. communicate. A water inlet hole 10 is provided on the side of the valve chamber 7, and a main valve seat 11 that forms the valve hole 9 by sandwiching the water inlet hole 10 and a sub valve seat 12 that protrudes annularly into the valve chamber 7 are provided. The valve seat 12 divides the valve chamber 7 into a main valve chamber 13 on the side containing the water inlet hole 10 and a sub-valve chamber 14. Both the valve part 15 and the sub-valve part 16 located in the sub-valve chamber 14 and facing the sub-valve chamber 12 are shaped like a cone, and both the valve parts 15 and 16 are simultaneously connected to the corresponding valve seats 11 and 12. Install them so that they are separated from each other.
17 is a pressure spring that presses the valve body 3 so that the tip of the valve body 3 is always in contact with the pressure receiving plate 4; 18 is a communication hole provided in the main valve portion 15, which connects the sub valve chamber 1 through the center of the valve body;
4 and the secondary pressure chamber 8 are communicated with each other. 19 is subject 6
The governor spring 5 is interposed between the spring receiving plate 19 and the pressure receiving plate 4 to repel them. 20 is a water passage hole formed in the pressure receiving plate 4. Note that 21 is a fixing nut that is an example of a means for fixing the main body 6.
かかる構成において、入水孔１０から弁室７に
流入した水は弁孔９を通り、受圧板４の通水孔２
０を通つて主体２から流出してゆく。 In this configuration, water flowing into the valve chamber 7 from the water inlet hole 10 passes through the valve hole 9 and flows through the water hole 2 of the pressure receiving plate 4.
It flows out from subject 2 through 0.

量を一定に保つように作用するのである。 At this time, due to resistance when water passes through the flow holes 20 of the pressure receiving plate 4, a pressure difference occurs between the pressure on the upstream side of the pressure receiving plate 4 and the pressure on the downstream side of the pressure receiving plate 4 in the secondary pressure chamber 8.
The pressure receiving plate 4 is pushed downstream by a force corresponding to the product of this pressure difference and the effective pressure receiving area of the pressure receiving plate 4, and a force corresponding to the difference between the spring pressure of the governor spring 5 and the spring pressure of the pressing spring 17 The pressure receiving plate 4 is pushed upstream.
The pressure receiving plate 4 moves to a position where the two forces are balanced, and the valve body 3, which is urged to contact the pressure receiving plate 4, follows the pressure receiving plate 4 and moves, so that the main valve portion 15 closes in the valve hole. 9, the opening degree of the valve hole 9 is adjusted. That is, when the pressure difference becomes large, the pressure receiving plate 4 and the valve body 3 move downstream, causing the main valve part 15 of the valve body 3 to reduce the opening degree of the valve hole 9, and conversely, when the pressure difference becomes small, the pressure receiving plate 4 and the valve body 3 move downstream. 4 and the valve body 3 move upstream to increase the opening degree of the valve hole 9. Therefore, even if the water supply pressure fluctuates, the flow rate remains constant.

ある。(Effects of the invention) The constant flow water governor of the invention has the following excellent effects. In other words, the flow rate is adjusted to a constant level based on the sliding of the pressure receiving plate within the cylindrical main body without using a diaphragm, making it possible to significantly reduce the size.Moreover, all movable members are incorporated within the cylindrical main body. This makes it extremely easy to install in water passages, and it can be manufactured at low cost, so it has great practical value when used in water heaters.
