排水量を多くする問題がでてきている。In the former edging valve A shown in FIG. 2, the above-mentioned conventional means is the check valve a and the intake valve b in the valve chamber 3a which are vertically opposed to each other. Are stored in such a state that they can be moved relative to each other within a certain range so that they can move up and down together, the check valve a pushes down the intake valve b, and the intake valve b is moved to the intake valve seat 34. The auxiliary valve of the auxiliary valve mechanism 6 causes the intake valve b to incline laterally with respect to the intake valve b to make the pressure contact with the intake valve seat 34 incomplete when the valve is pressed against the intake valve b. The auxiliary valve element 61 of the auxiliary valve mechanism 6 is laterally oscillated in the inner cavity of the shaft-cylindrical coupling member 4a, although the oscillating operation of the auxiliary valve element 61 prevents the valve element 61. The parts can be inspected by holding them in a state in which they have a degree of freedom so that they can be performed freely. And that the increase is production cost Te Kuna',
Errors due to the combination of the respective parts are concentrated on the valve closing operation of the auxiliary valve mechanism 6, so that the auxiliary valve mechanism 6 is not closed promptly,
Therefore, the closing of the intake valve b tends to be delayed, which causes a problem of increasing the amount of drainage to the outside.

ある。In the latter means, which is disclosed in Japanese Utility Model Laid-Open No. 3-14379, when the check valve body opens due to the flow from the pipe, the pressure-sensitive sliding body is integrated with the check valve body. The two springs, the first spring that is connected to the check valve and the second spring that is connected to the check valve for the backflow prevention chamber, are compressed, so that the flow rate of the flow that opens the check valve body is reduced. However, it is necessary to have an amount that opposes the sum of the spring forces of these two springs, the first spring and the second spring, which makes it impossible to use at a small flow rate, and the operation of the backflow prevention device becomes impossible. There is a question of uncertainty.

行なわれるようになる。As described above, the rim cut valve mainly used in the bath with the water heater according to the present invention has the non-return valve a and the intake valve b, which are vertically opposed in the valve chamber 3a. The suspension member 7 provided on the lower surface side of the check valve a is used for connecting together so as to move up and down together while allowing relative movement within the range.
By engaging the engaging claw portion 70 at the lower end with the engaging claw portion 80 at the upper end of the receiving member 8 provided on the upper surface side of the intake valve b.
For the check valve a, the intake valve b has the engaging claw portion 70 and the engaging claw portion 80.
The auxiliary valve valve body 61 and the auxiliary valve valve seat 60 are integrally mounted on the check valve a and the intake valve b, respectively, so that the auxiliary valve valve body 61 and the auxiliary valve valve seat 60 are integrally rocked. Since the check valve “a” is installed, the abutment between the auxiliary valve valve body 61 and the auxiliary valve valve seat 60 is inclined due to an error in the lowering operation of the check valve a. In this case, the deviation is absorbed by the swing of the intake valve b with the abutting point w as the fulcrum, and the auxiliary valve mechanism 6 comes to close correctly. Since the spring connected to the intake valve b is omitted, the check valve a can be opened exactly by pressing one spring 41. Therefore, the check valve a can be appropriately operated even with a small flow rate. Like

The influence exerted on the auxiliary valve mechanism 6 and the intake valve b can be reduced quickly and appropriately, and the amount of drainage to the outside can be reduced.
