摘要： PROBLEM TO BE SOLVED: To provide a self-closed faucet of a diaphragm valve capable of maintaining a water supply time for a long period.
SOLUTION: A valve element 10 is constituted of a center part 11 moved onto and apart from a valve seat 3, a peripheral edge part 13 fitted water-tight to the peripheral part of the valve seat 3, a flexible part 12 connecting the center part 11 to the peripheral edge part 12, and an energizing means such as a spring S for acting an energizing force to the center part 11 in a seating direction when the valve element center part 11 is separated a specified distance from the valve seat 3. When a water supply is stopped, water is allowed to flow in a water chamber 20 through the water passing hole 15 of the valve element 10 to lower the valve element 10 at a raised position. Since the valve element center part 11 is pressed by a reaction from the spring S in a downward direction, a flow is lowered for a long period. Accordingly, even when the lift stroke of the valve element 10 is set large, a force in the seating direction acts surely on the valve element 10. As a result, the seating operation of the valve element 10 is stabilized and a water supply time can be controlled constantly.

摘要： PROBLEM TO BE SOLVED: To provide a diaphragm type cut-off valve which prevents water hammer at the time of closing the valve and is applicable to a flushing valve device of a cistern. SOLUTION: In the diaphragm type cut-off valve with a rubber diaphragm valve element 16 having a central closing part 22 for blocking a passage by seating on a valve seat, a fixing part 20 of an outer peripheral part and a flexible part 28, which is positioned between the closing part 22 and the fixing part 20 and is in a folded shape when used, for giving displacement capability in a axial center direction to the closing part 22, the diaphragm valve element 16 is formed in a hat shape which is the shape of the flexible part 28 when unfolded and then the flexible part 28A of formed product is folded and the formed product is deformed so that the fixing part 20 and the closing part 22 come to close in the axial center direction in the state of being used, and the diaphragm valve element 16 is set while the formed product is deformed as such.

摘要： PROBLEM TO BE SOLVED: To feed water by the amount of money of an inserted coin without using a commercial power supply. SOLUTION: A quantitative water feeding device is provided with a switching valve 15 connected to a water source 20 having a fixed water pressure or above and storing a valve element 24a capable of passing or cutting the water from the water source 20 to a discharge side, a fluid pressure actuator 16 fitted to the switching valve 15 and having a piston 30 in it for opening or closing the switching valve 15 interlockingly with the valve element 24a, a flow adjusting means 18 slowly moving the piston 30 in the closing direction of the valve element 24a by adjusting the flow of the water from the water source 20 and feeding it into a sealed pressure chamber 36 formed in a case 25 on one end side of the piston 30, an energizing means invariably energizing the other end side of the piston 30 in the opening direction of the valve element 24a with the pressing force smaller than the water pressure applied to one side end of the piston 30, and a solenoid valve 17 connected to a timer 43 via a DC power supply 44, opened for a fixed period when the coin is inserted, and discharging the water in the pressure chamber 36 on one end side of the piston 30 to temporarily reduce the water pressure in the pressure chamber 36.

摘要： PROBLEM TO BE SOLVED: To surely prevent liquid from leaking and make a constant discharge rate property more excellent by providing a pressurizing member changing volume of a pressurized chamber so as to be able to pressurizedly discharge, raising liquid pressure in the pressurized chamber, and opening a valve element so as to discharge the liquid at a constant rate. SOLUTION: A valve seat 27 is formed on the edge part of the boundary of a pressurized chamber 21 and a discharge chamber 25, and a valve mechanism is constituted of the valve seat 27 and the taper part 33 of a valve element 30. By action of the valve element 30, the pressurized chamber 21 and the discharge chamber 25 are communicated to each other and partitioned into the separated chambers. A nozzle 28 for communicating with the discharge chamber 25 and discharging liquid is formed. A pressurizing member 40 put in the pressurized chamber 21 in a tightly closed state, changing the volume of the pressurized chamber 21, raising the liquid pressure in the pressurized chamber 21, and enabling the liquid to pressurizedly discharge, is formed in the upper part of the pressurized chamber 21 slidably in the vertical direction. The pressurizing member 40 is a slidable rod, it is connected to a pressurizing piston part 45, and the pressurizing piston part 45 is slidably provided in a cylinder 50.
