When magnet piece is less than moment of the spring to the down force of dynamic iron core to the upward active force of dynamic iron core, dynamic iron core is in cavity volume
Set back, diaphragm gland is sealed, the water in valve element external member is nowhere drained, and hydraulic pressure gradually increases, and gradually promotes valve element
Main body is moved down up to watertight rubber pad closes water inlet, and water route progressively closes off, push-button reset.
A kind of Delayed self-closing flushing valve of the present invention, breaks the traditional structure of Delayed self-closing flushing valve, it is ingenious will be ferromagnetic
Effect, time delay spring and damping oil between block and dynamic iron core combine the effect of ferromagnetic block respectively, design a knot
The novel Delayed self-closing flushing valve of structure, only need to press button, just can realize automatically opening up the purpose with time-delay closing water route, and
Pressing process need to only overcome damping oil and time delay spring to the collective effect power of ferromagnetic block, influence of hydraulic pressure not received completely, therefore press
Feel lighter than relatively labor-saving during pressure button.According to the different demands of user, by the viscosity and time delay bullet that select damping oil
The coefficient of elasticity of spring, can be adjusted to the delay time of the Delayed self-closing flushing valve.Rushed for same set of delayed self-close
Wash for valve, because the abrasion of time delay spring is small, damping oil is not revealed, the active force between magnet piece and dynamic iron core is lasting, because
This its delay time is accurate and fixed.
The present invention be it is a kind of open it is light and handy convenient, open after accurate time delay and the Delayed self-closing flushing valve that is automatically switched off,
Its reasonable in design, safe and reliable, each component wear is smaller during being opened and closed due to water route, therefore usage cycles
It is long.

When the combination of bonnet 6 link together, the external diameter of the internal diameter of the lower end of time delay bonnet 6 more than the upper end of valve element outer cover 1 so that time delay bonnet
There is gap, the water in pressure release water stream channel 33 passes through delivery port stream of this gap from valve element outer cover 1 between 6 and valve element outer cover 1
Go out, bar shaped bayonet socket (not shown) is provided with the side wall of the lower end of time delay bonnet 6, be provided with the lateral wall of valve element outer cover 1
The raised line (not shown) being engaged with each bar shaped bayonet socket, raised line is sticked into corresponding strip gab, just by time-delay valve
Lid 6 and the combination of valve element outer cover 1 link together.
After using said structure, a kind of Delayed self-closing flushing valve of the invention, operation principle is as follows：
(1) when being closed, the magneticaction that magnet piece 61 is produced to dynamic iron core 63 is insufficient for dynamic iron core 63
Upper shifting, dynamic iron core caulking gum 632 plays sealing function to the relief hole 32 of diaphragm gland 3, the hydraulic pressure in water pressure balance cavity 4 with
Quite, the water inlet (i.e. at via 11) of valve element outer cover 1 is sealed the hydraulic pressure of water inlet by watertight rubber pad 23, at water route
In closed mode；
(2) when button 81 is pressed, button 81 drives magnet piece 61 to be moved down near dynamic iron core, while dynamic iron core 63 is received
To the attraction of magnet piece 61, the opposition of spring 66 is gradually overcome, when magnet piece 61 is to the upward active force of dynamic iron core 63
More than spring 66 to moment of the down force of dynamic iron core 63, dynamic iron core 63 is moved up in cavity volume 65, now pressing diaphragm
The relief hole 32 of lid 3 loses the sealing function of dynamic iron core 63 so that the water in water pressure balance cavity 4 can be by diaphragm gland 3
Pod apertures 31 flow into relief hole 32, then the delivery port of valve element outer cover 1 is flowed to via pressure release water stream channel 33, now, due to
Pressure in water pressure balance cavity 4 is drained decompression, the pressure of water pressure balance cavity 4 and the intake pressure of water inlet form one it is bright
Aobvious pressure differential, intake pressure of the pressure less than water inlet in water pressure balance cavity 4, under the promotion of intake pressure, valve element master
Body 22 is moved up, and the water inlet of valve element outer cover 1 loses the sealing function of watertight rubber pad 23, the water inlet of valve element outer cover 1
It is connected with delivery port, water route is opened completely；
(3) due to being filled with damping oil in time delay chamber 7, and the lower end of magnet piece 61 is fixed with the time delay in compressive state
Spring 62, when release button 81, magnet piece 61 can be moved up slowly away from dynamic iron core 63, and dynamic iron core 63 gradually loses magnet
The attraction of block 61, when magnet piece 61 is less than down force of the spring 66 to dynamic iron core 63 to the upward active force of dynamic iron core 63
Moment, dynamic iron core 63 sets back in the cavity volume 65, and dynamic iron core caulking gum 632 is again to the relief hole 32 of diaphragm gland 3
Sealed, the same time, sub-fraction water is flowed to water pressure balance cavity 4 and intake and increased by the water inlet duct 24 in valve element main body 22
Pressure, the water in water pressure balance cavity 4 nowhere drains, and the pressure in water pressure balance cavity 4 gradually increases, gradually promote valve element main body 22 to
Lower movement closes water inlet up to watertight rubber pad 23, and water route progressively closes off, and button 81 resets.
A kind of Delayed self-closing flushing valve of the present invention, breaks the traditional structure of Delayed self-closing flushing valve, it is ingenious will be ferromagnetic
The effect of effect, time delay spring 62 and damping oil between block 61 and dynamic iron core 63 respectively to ferromagnetic block 61 combines, and designs
Go out the novel Delayed self-closing flushing valve of a structure, only need to press button 81, just can realize automatically opening up and time-delay closing water
The purpose on road, and pressing process need to only overcome damping oil and time delay spring 62 to the collective effect power of ferromagnetic block 61, not receive completely
Influence of hydraulic pressure, therefore feel during pressing button 81 lighter than relatively labor-saving.According to the different demands of user, by selecting damping oil
The coefficient of elasticity of viscosity and time delay spring 62, can be adjusted to the delay time of the Delayed self-closing flushing valve.For
For same set of Delayed self-closing flushing valve, because the abrasion of time delay spring 62 is small, damping oil is not revealed, magnet piece 61 and dynamic iron
Active force between core 63 is lasting, therefore its delay time is accurate and fixed.
The present invention be it is a kind of open it is light and handy convenient, open after accurate time delay and the Delayed self-closing flushing valve that is automatically switched off,
Its reasonable in design, safe and reliable, each component wear is smaller during being opened and closed due to water route, therefore usage cycles
It is long.
