Description
本发明涉及水压调节领域，具体为一种电动调节水压的操作装置。The invention relates to the field of water pressure regulation, in particular to an operating device for electrically adjusting water pressure.
对于一些使用软管对具体应用项目供水的场合，由于供水侧的水压一定，因此需要调节具体应用项目的水压时往往比较麻烦，增加升压器材需要耗费大量成本。而有时这种压力调节往往只是暂时性或者需要灵活地或者手动地调节的，因此增加升压器材也不能满足需要。For some applications where hoses are used to supply water to specific applications, since the water pressure on the water supply side is constant, it is often cumbersome to adjust the water pressure of a specific application item, and it takes a lot of cost to increase the pressure boosting equipment. Sometimes such pressure regulation is often only temporary or needs to be adjusted flexibly or manually, so increasing the booster equipment is not sufficient.
