Fluid control valve

Abstract

The invention provides a fluid control valve which comprises a shell defining an accommodating space; a valve seat, covering the inlet of the accommodating space, comprising a first flow channel and a second flow channel which are respectively in communication with an external water source, and being used for balancing the fluid pressure between the first flow channel and the second flow channel; and a control mechanism, arranged in the accommodating space, and further comprising a fluid outlet, the control mechanism being in communication with the first flow channel and the second flow channel and controlling fluid to flow out of the fluid outlet, and the control mechanism being used for adjusting the flow rate and the mixing proportion of the fluid flowing in from the first flow channel and the second flow channel, wherein the valve seat extends in the circumferential direction to form a pressing and abutting face, and the periphery of the inlet of the accommodating space abuts against the pressing and abutting face in a pressing mode and limits the valve seat to move in the axial direction of the shell. According to the technical scheme, the anti-extrusion effect can be achieved.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a fluid control valve. Background technique [0002] Fluid mixing valves, sometimes referred to as fluid control valves, are known in toilets or bathrooms for mixing cold and hot water together and for adjusting the mixing ratio (and thus water temperature) and flow. Typically, one manipulates the fluid mixing valve between two extreme states by turning the handle of the fluid mixing valve within a rotational range between the two extreme positions of the fluid mixing valve, a closed position and a maximum flow position. In the closed position, no water flows out of the fluid mixing valve; in the hot water maximum position, the water temperature is highest and the flow is greater. [0003] The existing fluid mixing valve has the following problems: when the fluid mixing valve is installed and used, for example, when it is installed on the faucet structure, when it is squeezed by ins...

AI Technical Summary

Problems solved by technology

[0003] The existing fluid mixing valve has the following problems: when the fluid mixing valve is installed and used, for example, when it is installed on the faucet structure, when it is squeezed by installation or hydraulic pressure, the existing fluid mixing valve is under pressure. The ability is weak, it is easy to cause deformation, which makes the user's manipulation feel cumbersome, and the internal structure is easy to pinch. In addition, when it is necessary to limit the temperature control range of the fluid mixing valve, it is usually necessary to make additional structures on the faucet structure, and at different temperatures Different limit structures are required when the range is required, the structure is complex and troublesome
