Bending deformation, the first valve 2053A of the one-way valve in the combined valve body is separated from the first air inlet 2052A of the vacuum bursting diaphragm, so that the first air inlet 2052A of the vacuum bursting diaphragm is in an open state, and the air flows from the first air inlet of the vacuum bursting diaphragm. The air inlet 2052A enters, which has a blasting effect.

Similarly, when negative pressure is generated in the second pipeline 2012 of the combined valve, the second deformed thin wall 2054B between the second valve 2053B of the one-way valve in the combined valve and the vacuum bursting diaphragm 2051 is bent due to the negative pressure. Deformation, the second valve 2053B of the one-way valve in the combined valve body is separated from the second air inlet 2052B of the vacuum bursting diaphragm, so that the second air inlet 2052B of the vacuum bursting diaphragm is in an open state, and the air enters the second vacuum bursting diaphragm. The gas port 2052B enters, which has a blasting effect.

During specific implementation, as shown in Figure 4, Figure 7a, Figure 7b and Figure 8, the first valve 2053A of the one-way valve in the combined valve body and the second valve 2053B of the one-way valve in the combined valve body are both arranged in the vacuum blasting The side of the diaphragm 2051 close to the second end 201b can effectively prevent water from rushing open the first valve 2053A of the one-way valve in the combined valve body and the second valve 2053B of the one-way valve in the combined valve body when water flows, resulting in water leakage.

In one embodiment, as shown in FIG. 4 , FIG. 5 a , FIG. 9 a and FIG. 9 b , the core check valve 204 includes a core check valve cavity 2041 , and the core check valve is sequentially arranged on the core check valve.

The movement check valve 204 further includes a movement check valve spring 2045 sleeved on the inlet water blocking column 20422 of the movement check valve.

More specifically, the core check valve bracket 2042 is provided with a core check valve inlet mounting post 20423 at one end close to the flush solenoid valve, and the core check valve sealing ring 2043 is sleeved on the The movement check valve is installed on the water inlet column 20423.

That is, if the core solenoid valve 202 is opened and the flush solenoid valve 207 is closed, water flows into the core pressure reducing valve 203 through the core solenoid valve 202, and the water is decompressed through the core After the valve 203 is stabilized, it flows through the one-way valve 205 in the combined valve body and the one-way valve 204 in the core to flow into the ceramic water diverting valve 206. During the flushing process, when the water flows into the one-way valve cavity of the core After 2041, an upward force will be applied to the movement check valve water inlet flap 20421, and the movement check valve inlet flap 20421 will be used to compress the core check valve spring 2045, so that the movement is unidirectional. There is a gap between the valve water inlet baffle 20421 and the periphery of the check valve cavity 2041 of the movement, so that water flows out from one end of the check valve cover 2044 of the movement.

If there is water backflow from the movement check valve cover 2044 into the movement check valve cavity 2041 (in the opposite direction of the arrow in Figure 9b), the backflow water will press the movement check valve sealing ring 2043 against On the side wall of the check valve cavity 2041 of the movement, water is prevented from flowing back into the combined valve body 201 and contaminating the combined valve body 201 and the valves arranged therein.

In one embodiment, as shown in FIG. 4 , FIG. 5 a , and FIG. 10 , the flushing check valve 208 includes a flushing check valve cavity 2081 , and is sequentially arranged in the flushing check valve cavity 2081 The flush check valve bracket 2082, the flush check valve sealing ring 2083, and the flush check valve socket 2084 arranged on the flush check valve cavity 2081;

Wherein, the flushing one-way valve sealing ring 2083 is sleeved on one end of the flushing one-way valve bracket 2082 close to the flushing solenoid valve 207;

The flush one-way valve nozzle 2084 is located at one end of the flush one-way valve bracket away from the flush solenoid valve 207 .

In this embodiment, the water in the flushing one-way valve 208 can only flow in the direction of the arrow (as shown in FIG. 10 ), which is essentially a one-way valve to prevent reverse flow of water. Compared with the structure of the core check valve 204, the structure of the flushing check valve 208 is the same except that the flushing check valve nozzle 2084 and the core check valve cover 2044 are different. same.

That is, if there is a reverse flow of water from the flush check valve nozzle 2084 into the flush check valve cavity 2081 (in the opposite direction of the arrow in FIG. 10 ), the reverse flow water will press the flush check valve sealing ring 2083 tightly. On the side wall of the flushing one-way valve cavity 2081 , water is prevented from flowing back into the combined valve body 201 and contaminating the combined valve body 201 and the valves provided therein.
