Abstract
The utility model provides a two-way high-pressure water pressure-regulating valve which can adjust high-pressure water jet equipment to operate stably under any pressure within a rated pressure range. The two-way high-pressure water pressure-regulating valve comprises an adjusting nut, a gasket, a spring, a valve rod, a fixing pin, a fixing sleeve, a flow guide block, a valve body, a bearing base, a steel ball, a supporting spring, a valve base, a sealing ring and a supporting ring.
