Abstract

The invention relates to an inner-threaded stop valve. The inner-threaded stop valve comprises a valve body, a valve cover, a locking nut, a valve rod, a valve blade and a hand wheel; 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 nut is in rotating connection to the valve rod and compresses the valve cover; the valve blade 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 blade is integrated with the valve rod; anticorrosion and antirust coatings cover the outer surface of the valve body and the inner wall of a valve cavity. The inner-threaded stop valve is anticorrosion, antirust and convenient to observe inside condition.

Description

technical field [0001] The invention relates to an internal thread cut-off valve, in particular to an anti-corrosion and anti-rust internal thread stop valve. Background technique [0002] The internal thread globe valve may be in contact with corrosive substances for a long time. The existing internal thread globe valve may have certain anti-corrosion performance, but under long-term harsh conditions, its protective performance is far from meeting the requirements, making the substrate easy to be damaged. Corrosion, leakage and other hazards. [0003] The existing internal thread cut-off 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 internal thread cut-off valve which is anti-corrosion and anti-rust and which is convenient for observing internal conditions. [0005] The techni...
