Description

a water heater valve

technical field

The invention relates to the field of valves, in particular to a water heater valve.

Background technique

The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. For example: the hot and cold water valve used in the water heater to control the water flow speed and water temperature. Most of the water heater valves are directly suspended at the bottom of the water heater, and the temperature and speed of the discharged water source are directly controlled through the water valve.
