Abstract

The invention discloses a filtering valve. A main body is a valve body which is divided into a front section, a middle section and a back section, the front section is of a hollow cylinder structure, a rotary knob is arranged on the front section, and a first-stage filtering net is arranged between the front section and the middle section; the middle section is of a hollow cylinder structure, a separating plate is arranged in the middle section, and an arc-shaped second-stage filtering net is arranged at the back end of the middle section; and a third-stage filtering net is arranged in the back section, and a handle switch is arranged on the back section. The filtering valve is simple in structure, lower in cost, convenient and rapid to operate and longer in service life; three-stage filtering is adopted, further filtering can be achieved, and a solution is more clean; a rotary cover can be opened, and impurities in the rotary cover can be removed; the valve is a multi-point type valve, the flow of the solution can be controlled, and convenience is brought to operation; and the impact force of the flow of the solution can be reduced through the separating plate, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing and processing, in particular to a stably closing valve. Background technique [0002] The valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, throttling, check, diversion or overflow relief. Valves used for fluid control range from the simplest shut-off valve to various valves used in extremely complex automatic control systems. Valves for industrial pipelines. It can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids. The working pressure of the valve can be from 0.0013MPa to 1000MPa ultra-high pressure, and the working temperature is from Ultra-low temperature of -270°C to high temperature of 1430°C. [0003] The filter valve ...
