Temperature control valve

Abstract

The invention discloses a temperature control valve. The temperature control valve comprises a valve body, wherein an upper valve hole is formed in the upper end of the valve body, a lower valve hole coaxial with the upper valve hole is formed in the lower end of the valve body, a water inlet and a water outlet are symmetrically formed in the left side surface and the right side surface of the valve body, and a water inlet valve assembly used for controlling on-off of the water inlet and a water outlet valve assembly used for controlling on-off of the water outlet are arranged in the valve body; a temperature control valve element assembly is inserted into the upper valve hole, the temperature control valve element assembly is used for controlling connection or disconnection of the water inlet and the water outlet, a valve lock assembly is fixedly arranged in the lower valve hole, when the valve lock assembly is used for locking the temperature control valve element assembly, the water inlet valve assembly opens the water inlet, the water outlet valve assembly opens the water outlet, when the valve lock assembly is used for unlocking the temperature control valve element assembly, the water inlet valve assembly closes the water inlet, and the water outlet valve assembly closes the water outlet. The temperature control valve is simple in structure, compact in size, convenient to install and maintain, and capable of cleaning and maintaining a valve rod and an upper valve block on line.

Description

technical field [0001] The invention belongs to the technical field of heating valves, in particular to a temperature control valve. Background technique [0002] With the implementation of welfare heating policy reform, various temperature control valves to adjust the indoor temperature of buildings have also entered the homes of ordinary people. The existing indoor temperature control technology mainly uses an automatic temperature control valve installed on the radiator to automatically adjust the flow rate of the heat medium in the radiator to achieve the purpose of controlling the indoor temperature. Due to the poor quality of general heating water and a large amount of sundries, after the temperature control valve runs for a period of time, its valve core and valve sleeve will be blocked and lose control; Repeated actions will cause the wear of the sealing ring and eventually lead to the leakage of the heat medium; in order to clean and maintain the temperature contro...

Problems solved by technology

[0003] (1) When it needs to be cleaned, the adjustment knob must be manually rotated first to rotate the valve sleeve by 90 degrees and then take out the valve core. Therefore, it is not only troublesome to operate, but also can only clean the valve core, but not the valve sleeve. And when the sealing surface of the valve sleeve is damaged for maintenance, the valve sleeve must be taken out, which loses the function of online maintenance;

[0004] (2) When the valve sleeve is rotated 90 degrees, the valve sleeve is sealed by the gap with the inner hole of the valve body, and the water in the water inlet and outlet will flow to the outside through the gap between the valve sleeve and the inner hole of the valve body, resulting in leakage and waste
