Abstract

The invention discloses a control valve with a cold water drainage function and a switching valve device. The control valve comprises a valve body part, a piston, a sliding pipe, a temperature-sensitive part, a back pressure spring and a handle mechanism. The valve body part is provided with an air inlet and an air outlet. The piston is slidably connected into the valve body part along an X direction. The sliding pipe is slidably connected into the valve body part along an X direction and sleeves outside the piston. Relative sliding between the sliding pipe and the piston is achieved. A connection and blockage passage connecting a water inlet with a water outlet is formed between the piston and the sliding pipe. Connection and blockage of the connection and blockage passage can be controlled by relative sliding of the sliding pipe and the piston. The temperature-sensitive part is installed in the valve part body and capable of abutting against the piston in order to generate abutting force. The back pressure spring is installed in the valve body part and capable of abutting against the piston in order to generate elasticity. The elasticity and abutting force are reversely arranged along an X direction. The sliding pipe is driven to slide by the handle mechanism. The control valve with the cold water drainage function and the switching valve device have following technical effects: the cold water drainage function is fulfilled; the function of opening or stopping hot water or cold water is achieved; and a compact structure is obtained.

Description

technical field [0001] The invention relates to a control valve and switching valve device with the function of draining cold water. Background technique [0002] China Patent Database authorized the announcement on 2009.04.15, the announcement number is CN201221645Y, a utility model named "comfortable cooling automatic valve", which includes a shell, a valve plug and a valve plug operating device, on the shell there are at least The hot water inlet and the cold water outlet, the valve plug is movable in the housing, and the sealing port matching the valve plug is provided in the housing, which is characterized in that it also includes a thermal reset device. When the thermal reset device is heated, it can move and can Directly or indirectly drive the valve plug until the valve plug is tightly sealed with the sealing port. When the thermal reset device is cooled and an external force is applied to the valve plug operating device, the valve plug operating device can move and ...
