Switch valve with temperature adjusting function

Abstract

The invention discloses a switch valve with a temperature adjusting function. An inserting hole is formed in a sealing film of the switch valve, and a clamping jaw is arranged on a film support and inserted in the inserting hole of the sealing film; an axial pressure relief hole is formed in the clamping jaw, and a bearing inner cover is mounted on a valve core body; a first spring is mounted between the bearing inner cover and the film support, and a back-pressure cavity is formed between the bearing inner cover and the sealing film; the back-pressure cavity and a water inlet channel communicate through a through hole or an interval, and the lower end of a sealing guide rod is provided with a plug and inserted into the pressure relief hole; the upper end of the sealing guide rod is provided with a pressing structure, and a second spring is mounted between the upper end of the sealing guide rod and the pressing structure; when the sealing guide rod is driven by the pressing structure to move upwards, the pressure relief hole is unblocked through the plug of the sealing guide rod; or when the sealing guide rod is driven by the pressing structure to move downwards, the pressure relief hole is blocked through the plug of the sealing guide rod. According to the switch valve with the temperature adjusting function, when the valve is driven through pressing to be opened or closed, the sealing guide rod of the switch valve cannot deflect, and the sealing effect is good accordingly.

Description

technical field [0001] The invention relates to the technical field of valve equipment, in particular to an on-off valve with temperature regulation. Background technique [0002] In the prior art, the publication number CN 206206700 U discloses a temperature-adjustable push switch valve, which includes a casing, a valve seat, a control assembly, a pre-pressurized water sealing mechanism, and a temperature-adjusting assembly; the temperature-adjusting assembly is connected with the valve seat to adjust The temperature component includes a moving tile and a fixed tile. The fixed tile is installed on the valve seat, and there are cold and hot water inlets on it. The moving tile is formed to block any water inlet or partially block the water inlet. The water sealing part and the mixing water chamber, the moving ceramic piece and the fixed ceramic piece also have water outlets respectively; the pre-pressurized water sealing mechanism includes a pressure-bearing inner cover, an i...

Problems solved by technology

[0004] Wherein, the lower end of the linkage rod directly passes through the pressure-bearing inner cover, and a plug is installed at the end of the lower end of the linkage rod, which drives the displacement of the pressing structure and drives the movement of the linkage rod, so that the plug at the lower end of the linkage rod opens. When the pressure relief hole on the sealing diaphragm is driven for a long time to displace the pressing structure and drive the linkage rod to move, the lower end of the linkage rod is prone to deflection, so that the plug at the lower end of the linkage rod and the pressure relief of the sealing diaphragm The sealing effect between the holes is poor, which affects the normal use of the switch valve
