Water mixing valve with pressure balancing mechanism

Abstract

The invention relates to a water mixing valve with a pressure balancing mechanism. The water mixing valve comprises a casing with a first inlet, a second inlet and a water outlet. The water mixing valve is characterized in that a pressure sensing channel and a sliding rod channel are arranged between the first inlet and the second inlet; one end of the pressure sensing channel is communicated with the first inlet; the other end of the pressure sensing channel is communicated with the second inlet; a sliding block is arranged in an inner cavity of the pressure sensing channel; one end of the sliding rod channel is communicated with the first inlet; the other end of the sliding rod channel is communicated with the second inlet; a sliding rod is arranged in an inner cavity of the sliding rod channel; two ends of the sliding rod are respectively connected with a first gate plate and a second gate plate; the pressure sensing channel is mutually parallel to the sliding rod channel; a connecting rod cavity is arranged between the pressure sensing channel and the sliding rod channel; a connecting rod is arranged in the connecting rod cavity; an intermediate section of the connecting rod is pivoted on the inner wall of the connecting rod cavity; two ends of the connecting rod are respectively hinged on the sliding block and the sliding rod; and in addition, a return device acting on the connecting rod is arranged in the casing. The water mixing valve is simple in structure and is convenient to use; and according to the water mixing valve, the pressures of two water inlet ends can be automatically adjusted according to the change of the water pressure; the pressure difference between two ends can be reduced as much as possible; accurate adjustment of the temperature is facilitated; and the phenomenon of blow hot and cold due to the instability of the water pressure can be avoided.

Description

technical field [0001] The invention relates to a water mixing valve with a pressure balance mechanism. Background technique [0002] Water mixing valves must be used in various shower facilities. After mixing hot water with higher temperature and cold water with lower temperature in a certain proportion, warm water with moderate temperature is produced for people to use. However, in actual use, due to the large pressure difference between cold and hot water, it is difficult to adjust the water temperature accurately, or the temperature just adjusted may be hot and cold due to unstable water pressure, which is inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide a water mixing valve with a pressure balance mechanism which is easy to operate and easy to use, so as to avoid the phenomenon of hot and cold caused by unstable water pressure. [0004] To achieve the above object, the present invention adopts the following tec...
