Problems solved by technology

[0002] In the current tap water supply, the tap water supply pressure is basically maintained between 0.25 and 0.35MP. Due to many reasons such as uneven construction quality or aging of pipes, fittings, and valves, it is easy to cause running, popping, dripping, and leakage. Difficult phenomenon that causes waste of water resources and loss of money

Abstract

The invention discloses a water-saving control valve for tap water, which comprises a valve body, a water inlet and a water outlet. The valve also comprises a valve rod arranged in the valve body, a sealing ring fixedly arranged on the valve rod, a sealing grid arranged on the valve body, a check base, a check spring, a floating diaphragm, a diaphragm gland and a pressure regulating elastic device. When the water is used, the water pressure under the floating diaphragm is decreased, the floating diaphragm pushes the valve rod to move downwards under the action of the pressure regulating elastic device, the valve rod drives the sealing ring to move, the sealing ring leaves the sealing grid, the tap water flows to the water outlet through the gap between the valve rod and the sealing grid, and at the moment, the water pressure is decreased and the impact of the tap water on a water using device is decreased. When the water is not used, the water pressure under the floating diaphragm is increased, the floating diaphragm moves upwards, the valve rod moves upwards under the action of the check spring, and the sealing ring and the sealing grid are clamped together so as to cut off the tap water, decrease the probability of water leakage, lower the corrosion rate, and greatly decrease the explosive probability of the water using device.

Description

technical field [0001] The invention relates to a valve used in the field of running water. Background technique [0002] In the current tap water supply, the tap water supply pressure is basically maintained between 0.25 and 0.35MP. Due to many reasons such as uneven construction quality or aging of pipes, fittings, and valves, it is easy to cause running, popping, dripping, leaking, etc. Difficult to solve the phenomenon, and cause the waste of water resources and the loss of funds. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water-saving control valve for running water that can effectively prevent water leakage and reduce the pressure on water-using devices. [0004] In order to solve the above technical problems, the technical solution of the present invention is: tap water water-saving control valve, including a valve body, the valve body is provided with a water inlet and a water outlet, the valve bo...
