Problems solved by technology
The structural design of the existing pressure-bearing water tank pressure relief valve is unreasonable. There is a point contact between the valve core and the inner wall of the valve. The water flows through the gap between the valve core and the inner wall of the valve to the baffle. Flow direction, and then reach the water outlet, so the water flow is prone to turbulence, causing the valve core assembly to vibrate violently in the housing, which in turn generates noise, affecting the comfort of the user

The invention relates to the field of water pump devices, in particular to a filtering type pressure holding valve. The filtering type pressure holding valve comprises a valve body and a valve lid installed on the valve body; the filtering type pressure holding valve is characterized by further comprising a pump inlet device, a piston filtering device and a pump outlet device, one end of the piston filtering device is connected with the pump inlet device, the other end of the piston filtering device is connected with the pump outlet device, and the piston filtering device is installed inside the main valve body. The filtering type pressure holding valve is novel in design and is mainly used for decompression of a high-rise building testing and circulating system to prevent a system fault caused when water pressure is too high, and is automatically controlled through water power, other devices and energy are not needed, the maintenance is simple, one valve has multiple purposes, the practicability is high, and the market prospect is good.
Description
technical field [0001] The invention relates to the field of water pump devices, in particular to a filter type pressure sustaining valve. Background technique [0002] At present, the pressure relief valve of the existing pressure-bearing water tank is installed on the water inlet pipe, and the user needs to flow through the pressure relief valve to enter the water tank when using water normally. The structural design of the existing pressure-bearing water tank pressure relief valve is unreasonable. There is a point contact between the valve core and the inner wall of the valve. The water flows through the gap between the valve core and the inner wall of the valve to the baffle. In this way, the water flow is prone to turbulent flow, causing the valve core assembly to vibrate violently in the housing, which in turn generates noise and affects the comfort of the user. Therefore, it is necessary to propose a filter type pressure sustaining valve to solve the above problems. ...
