Embodiment 1

[0027] See Figure 1-2. The inlet and outlet valve seats (2) are connected to the self-inlet pipe. When it is normally closed, the water chamber (5) is filled with water, and its pressure is equal to that of the water supply, so that the A surface of the central diaphragm valve core (1) The middle part is flatly attached to the water inlet valve port (11). In order to make the seal more reliable, an "O" type rubber ring (12) can also be embedded in the ring end surface of the water inlet valve port (11) to form a central diaphragm valve disc against the " The two-way flexible sealing ring surface of the O” type rubber ring (12) is soft to soft, not the corresponding sealing surface of steel, and is clamped between the edges of the annular oblique concave wide groove drainage cavity (14) Porous stop ring (4) (see image 3 ) to limit the central diaphragm spool (1) to float unevenly within the set range, so as to avoid fatigue damage caused by deformation and transition. . When ...

Embodiment 2

[0029] see Figure 4 The invisible integral button cover (13) is a flexible reinforced glue layer (14) attached to the inner wall of the stainless steel sheet molding, and a solid gasket (15) is fixed in the middle of the glue layer to form an elastic outer steel inner flexible composite button cover (13). Press or step on the middle part, using its characteristic of small-scale unevenness, the solid washer (15) is linked with the "T" type pressure relief valve (9) to relieve the pressure of the water chamber cavity (5), and the flow through the pressure relief channel (7) Go, the central diaphragm spool (1) then deflects to the side of the water chamber cavity (5), which is equivalent to the drainage station where the valve clack is opened. The axial rear end of the "T" type pressure relief valve (9) can also be connected with a through needle (8) or a vortex vibrating needle (18) that can be rotated by water flow through the damping hole (6), so that each flushing of the toi...

Embodiment 3

[0033] The structural principle of this embodiment is basically the same as that of the previous embodiment, the difference is that the inlet and outlet pipes are connected to the pipeline in reverse phase (see Figure 6 ) shows that the central diaphragm valve core (1) is strengthened, that is, the reinforced bump (19) with a little thickness is added, and the damping hole (6) is riveted to the central diaphragm valve core (1), deviated from The center of the hole on one side of the center is inserted through the needle or the vortex trembling needle (18), and the same principle reaches the self-closing purpose of time delay, but the porous limit retaining ring (4) can be exempted. Because the central membrane spool (1) has the same water pressure on both sides except the central reinforcement area, the central membrane spool (1) will not be damaged.

Abstract

This invention relates to a water-save time delay valve device in toilet in which, a center film valve core capable of concave-convex floating is mounted on the inlet valve base shaped in a round concave glue piece, an orifice nozzle is insertedin the center with a through needed in the orifice, a decompressing valve is set on an abnormal inner cover implied solid button made of compound material, rigid outside and soft inside, changeable by concave and convex. The decompressing valve is open or close either by hand or foot when fixing the valve on the ground since the ground pollute can't enter into the solid implied button.

Description

technical field [0001] The invention relates to a time-delayed self-closing valve for flushing toilets and toilets. Background technique [0002] The existing time-delay self-closing valve has a general structure. The valve flap that closes the valve port is made into a piston shape, one end closes the valve port, and the other end can slide in a cylinder cavity. There is a small damping hole in the cylinder cavity or rely on the cylinder wall and The gap between the pistons communicates with the water supply, and there is an orifice on the piston that communicates with the drain pipe. When not flushing, the orifice is closed, and the cylinder cavity is filled with water and equal to the pressure of the water supply, so that the valve disc is pressed against the valve port, and the water is flushed. At the same time, just open the orifice for a short time, the water in the cylinder cavity will be released, the piston will be pushed up by the water supply pressure for a certa...
