Description

Water leakage prevention steering valve Technical Field The utility model mainly relates to the technical field of steering valves, in particular to a water leakage prevention steering valve. Background The steering valve, also called a direction control valve, is an important component in a fluid control system, and is mainly used for changing the flow direction of fluid so as to meet the requirements of various process flows, and is generally composed of a valve body, a valve core, a spring, a sealing element and the like, wherein the valve core is a key component for controlling the flow direction of the fluid. The connection relation of the fluid channel can be changed by rotating or moving the valve core, so that the change of the fluid flow direction is realized, and the problems of sealing performance reduction and water leakage are easy to occur because the pressure in the steering valve is always changed and the rotation times are large.
