Embodiment 1

[0025] a valve such as figure 1 As shown, valve body 1 is provided with water inlet 101, water supply chamber 102, water outlet A103, water outlet chamber 104, valve seat A107, A chamber 108, valve seat B110 and B chamber 111, the water inlet communicates with the water supply chamber, and the water outlet communicates with the water supply chamber. The water outlet chamber is connected, the valve seat A is located in the water supply chamber, and the valve seat B is located in the B chamber. There is a through hole A109 between the A chamber and the B chamber. The valve seat A is equipped with a valve disc 2, and the valve disc is provided with a side hole 21. , the back pressure surface of the valve disc is located in chamber A, and the valve seat B is equipped with an opening and closing member for opening and closing the valve seat B. The opening and closing member is composed of a cap 3, a pull rod 4, a sealing ring 5 and a return spring A6. The cap Located in chamber B 1...

Embodiment 2

[0030] like figure 2 Shown, this example is different from the previous example in that the opening and closing member of the opening and closing valve seat B is composed of a cap 3, a piston 13, a spring 14, a pull rod B15, a sealing ring 5 and a return spring A6, and the cap is located in the cavity B and is connected with the Corresponding to valve seat B, the piston is located in chamber B and the front end of the piston is connected to the cap. The front part of the tie rod B is located in the chamber B. The front part of the tie rod B is provided with a blind hole 152. The front part of the blind hole wall is provided with a card slot 151. The end has a claw 132, which is located in the groove, so that when the pull rod B is pulled back, the piston is pulled back by the pull rod B, and the spring is located in the blind hole of the pull rod B and is located at the rear end of the piston and the blind hole. between the bases. Different from the above example, the valve ...

Embodiment 3

[0034] like image 3 , Figure 6 As shown, the difference between this example and Example 2 is that a spacer 16 is arranged between the rear end of the piston and the spring. Other structures are the same as in Example 2. The reset of the piston is more reliable like this.

Abstract

The invention relates to a valve applicable to washing and capable preventing closing difficulty and poor closing. The valve comprises a valve body (1). A water inlet (101), a water supply chamber (102), a water outlet A (103), a water outlet chamber (104), a valve seat A (107), an A cavity (108), a valve seat B (110) and a B cavity (111), wherein the water inlet is communicated with the water supply chamber, the water outlet is communicated with the water outlet chamber, the valve seat A is located in the water supply chamber, the valve seat B is located in the B cavity, the A cavity is communicated with the B cavity through a through hole A (109), a valve flap (2) is matched on the valve seat A, a bypass hole (21) is formed in the valve flap, backpressure face of the valve flap is located in the A cavity, a valve seat B opening and closing component is matched on the valve seat B, a water outlet B (105) communicated with the air is formed in the valve body, a through hole B (106) is formed in the valve body, one end of the through hole B is communicated with the B cavity, and the other end of the through hole B is communicated with the water outlet B. The valve is suitable for being used as a washing valve.

Description

technical field [0001] The invention relates to the field of sanitary equipment products, in particular to a valve related to spraying and flushing. Background technique [0002] The toilet is an indispensable sanitary appliance in people's life. All toilet flush valves are equipped with toilet flush valves. With the advancement of technology, toilet flush valves are also constantly developing, from the previous button type, pressure rod type, and pedal type to the current induction type. The specification of Chinese CN2018832506U discloses a flush valve with a solenoid valve pressure relief device. In this technical solution, an inductive electromagnetic switch is used to control the pressure in the flush valve, so as to control the opening and closing of the flush valve. But this flushing valve only controls the opening and closing of valve by electromagnetic switch, when running into power failure or circuit fault, this flushing valve just can't normally use, has brought...
