Abstract

The invention relates to an external threaded angle stop valve, which comprises a valve body, a valve cover, a locking screw nut, a valve rod, a valve flap and a hand wheel, wherein the valve cover is arranged on a sealing contact surface of the valve body, the valve rod is connected with the valve body and the valve cover, the locking screw nut is rotationally connected onto the valve rod and tightly presses the valve cover, the valve flap is connected with the lower end of the valve rod, the hand wheel is connected with the upper end of the valve rod, the valve flap and the valve rod are of an integral structure, bottom layers consisting of aluminum oxides and silicon oxides cover the outer surface of the valve body and the inner wall of the valve cavity, and surface layers formed by aluminum oxides, mullite and clay also cover the bottom layers. The invention provides the anti-corrosive and anti-rust external threaded angle stop valve convenient for people to observe inside conditions.

Description

technical field [0001] The invention relates to an external thread angle stop valve, in particular to an external thread angle stop valve with a protective layer. Background technique [0002] Angle globe valves with external threads may be in contact with corrosive substances for a long time. Existing angle globe valves with external threads may have certain anti-corrosion properties, but under harsh conditions for a long time, their protective performance is far from meeting the requirements, making The base material is easily corroded, causing leakage and other hazards. [0003] The existing external threaded angle stop valve cannot observe the internal condition of the valve body, which is unfavorable for repair and maintenance. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art and provide an external threaded angle stop valve which is anti-corrosion and anti-rust and which is convenient for observing i...
