Problems solved by technology

[0002] Slab gate valves have been widely used in petroleum, chemical industry, long-distance pipelines, oil terminals and irrigation areas. Slab gate valves have the advantages of good sealing performance, long service life, small opening torque, and short structural length. Medium leakage sometimes occurs at the rod seal, which is very difficult to deal with now and affects the normal operation of the valve

Abstract

The invention discloses a stable anti-leakage lubricating gate valve which comprises a shell, valve covers and a spherical valve rod. The valve covers are fixedly connected to the shell through bolts. The spherical valve rod is arranged in the shell, and the two ends of the spherical valve rod extend out of the valve covers respectively. Locking rings are arranged at the positions, at the extending ends of the spherical valve rod, of the valve covers. The part, in the shell, of the spherical valve rod is provided with reinforcing rings. The parts, arranged at the inner end of the shell, of the valve covers are provided with sealing rings. A stable cover is arranged outside the middle of the part, arranged in the shell, of the spherical valve rod. A stable spring is arranged in the stable cover. An oil guide pipe is arranged on the shell. One end of the oil guide pipe stretches into the shell, and the other end of the oil guide pipe stretches out of the shell and is sealed by a sealing cover. According to the scheme, stability during running is provided, the service life is greatly prolonged, and the leakage of the gate valve is effectively avoided.

Description

technical field [0001] The invention relates to a smooth and leak-proof lubricating gate valve, which belongs to the technical field of flat gate valves. Background technique [0002] Slab gate valves have been widely used in petroleum, chemical industry, long-distance pipelines, oil terminals and irrigation areas. Slab gate valves have the advantages of good sealing performance, long service life, small opening torque, and short structural length. Medium leakage sometimes occurs at the rod seal, which is very difficult to deal with now and affects the normal operation of the valve. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to propose a smooth leak-proof lubricating gate valve with good sealing effect and stable operation. [0004] The technical solution of the present invention is achieved as follows: a smooth leak-proof lubricating gate valve, including a housing, a valve cover and a spherical valv...
