Hydraulic control valve with filtering function

Abstract

The invention discloses a hydraulic control valve with a filtering function, which comprises a valve body and a valve disc. The two ends of the valve body are respectively provided with a water inlet and a water outlet. The inside of the water inlet port is screwed with a connecting piece. The other end of the connecting piece is welded with a spiral pipe, and the spiral pipe runs through the connecting piece, a filter layer is welded in the valve body, a sand storage tank is installed at the bottom of the valve body, and an upper baffle plate and a sand storage tank are respectively welded in the valve body. The lower baffle, the upper baffle and the lower baffle are respectively close to the water inlet and the water outlet, a cavity is installed above the valve body, and connecting plates are welded on both sides of the top and bottom of the side of the cavity, The valve clack is located between the upper baffle plate and the lower baffle plate, and the middle part of the upper surface of the valve clack is welded with a connecting rod. The connecting rod runs through the valve body and is located in the cavity and the valve cover. Connected with a compression spring, this hydraulic control valve with filtering function has a simple structure, which ensures the long-term use of the device and reduces the cost of installation.

Description

Technical field [0001] The invention relates to the technical field of industrial valves, in particular to a hydraulic control valve with a filtering function. Background technique [0002] Hydraulic control valve is one of the most common valves in people's daily life, and it is closely related to people's life. Hydraulic valves are widely used in building piping, industrial water supply, fire-fighting facilities, HVAC, and irrigation systems. They are generally used to reduce pressure, hold pressure, relieve pressure, adjust flow, control water level, and prevent water hammer. The water conservancy control valve is a valve that is powered by the pressure of the pipeline medium to open, close and adjust. It consists of a main valve and attached conduits, needle valves, ball valves and pressure gauges. According to the purpose of use and different functional places, it can be evolved into a remote control float valve, a pressure reducing valve, a slow closing check valve, and a ...

AI Technical Summary

Problems solved by technology

[0003] During the use of existing devices, a filter device is usually connected to the water inlet to filter and remove impurities from the incoming water. However, connecting the filter device externally will increase the volume of the hydraulic control valve and increase the occupied space. , and increase the cost of installation, while the control valve with filtering function will cause damage to the filtering parts due to the impact of water flow, which is not conducive to long-term use
