Detailed Description

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

Please refer to fig. 1, the utility model provides a flow valve structure for household electrical appliances uses, it includes valve body shell 1 and locates the valve core body of valve body shell 1 inside, the internal first cavity 2 and the second cavity 3 that are equipped with of valve core, it separates to be provided with elasticity diaphragm capsule 4 between first cavity 2 and the second cavity 3, communicate through constant current channel 5 between first cavity 2 and the second cavity 3, the valve core body is equipped with first flow port 6 of being connected with first cavity 2 and the second flow port 7 of being connected with second cavity 3, elasticity diaphragm capsule 4 can change the size of first flow port 6 and/or second flow port 7 along with pressure variation.

Specifically, when the flow rate input to the first flow passage port increases, the elastic membrane block is pressed downwards, the first flow passage port becomes larger, the second flow passage port becomes smaller, the pressure of the first chamber increases, the fluid flowing through the constant flow passage increases, but the pressure of the second chamber also increases because the second flow passage port becomes smaller, the pressure difference between the first chamber and the second chamber is the same as that before the flow rate increases and does not change, and the flow rate flowing through the passage does not change because the cross-sectional area of the passage connecting the two chambers is constant, so the flow rate flowing out of the second flow passage port also does not change; on the contrary, when the flow rate input to the first flow passage port is reduced, the elastic diaphragm rebounds, the first flow passage port is reduced, the second flow passage port is enlarged, the pressure of the first chamber is reduced, and the fluid flowing through the constant flow passage is reduced.

The valve core body consists of an upper valve core 8 and a lower valve core 9, the elastic membrane block 4 is pressed on the lower valve core 9 through the upper valve core 8, and when the elastic membrane block has insufficient elasticity, the elastic membrane block can be replaced by disassembling the upper valve core and the lower valve core.

Lower valve core 9 has inclined plane 91 and is used for the bearing elasticity diaphragm 4 adopts inclined plane and elasticity diaphragm contact, when elasticity diaphragm pressurized pushes down, can contact with the inclined plane better, helps strengthening the leakproofness.

The number of the constant flow channels 5 is multiple, and the plurality of constant flow channels 5 are uniformly distributed on the lower valve core 9 in the circumferential direction, so that fluid can flow from the first chamber to the second chamber more smoothly and uniformly.

The valve body housing 1 is provided with a first port 10 connected to the first flow port 6 and a second port 11 connected to the second flow port 7, so that the fluid pipeline is connected by the first port and the second port, and the fluid flows into the chamber inside the valve core body.

The valve body shell 1 comprises an upper shell 12 and a lower shell 13, the upper shell 12 and the lower shell 13 enclose a cavity for installing the valve core body, the upper shell 12 and the lower shell 13 are connected and fixed together through a connecting piece and are fixed through the connection of the upper shell and the lower shell, so that the connection of the upper valve core and the lower valve core is ensured, when the valve core body needs to be opened, the upper shell and the lower shell are detached only by detaching a screw, and the valve core body can be directly opened.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, but all equivalent modifications or changes made by those skilled in the art according to the present invention should be included in the protection scope of the claims.
