Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a long-life cock valve for industrial oil production, which can filter sediment and impurities, improve the service life of the cock valve, avoid fixing bolts from rusting, and facilitate subsequent disassembly and maintenance , can limit and fix the valve stem, prevent the advantages of rotation, and solve the sediment and sundries in the industrial oil, which are easy to be adsorbed on the inner wall of the plug valve, which is not easy to clean, which will cause the plug valve to be blocked, and the water vapor in the air is easy to If it enters the bolt holes and the fixing nuts, it will cause the fixing bolts and fixing nuts to rust, making it difficult to disassemble and repair. When the handle is bumped, it will affect the flow of the valve.

Abstract

The invention relates to the field of plug valves, and discloses a long-service-life plug valve for industrial oil production. The long-service-life plug valve comprises a valve body, a connecting flange, a valve connecting pipe, a first connecting plate and a second connecting plate, and is characterized in that a clamping groove is formed in the outer surface of the connecting flange, and a filtering structure is arranged in the valve connecting pipe; a groove is formed in the outer surface of the upper end of the first connecting plate, a first sealing ring is arranged in the groove, bolt holes are formed in the outer surface of the first connecting plate and the outer surface of the second connecting plate, fixing bolts are arranged in the bolt holes, and a sealing gasket is arranged on the outer surface of the first connecting plate; and a through hole is formed in the outer surface of the sealing gasket, a fixing nut is arranged on the outer surface of the lower end of the second connecting plate, and a second sealing ring is arranged on the outer surface of the fixing nut. The long-service-life plug valve for industrial oil production has the advantages of being long in service life, convenient to disassemble and capable of limiting a handle.

Description

technical field [0001] The invention relates to the field of charging equipment, in particular to a long-life plug valve for industrial oil production. Background technique [0002] The plug valve is a closing member or a plunger-shaped rotary valve. By rotating 90 degrees, the channel port on the valve plug is the same as or separated from the channel port on the valve body to realize opening or closing. It is a valve that cannot be used in industrial oil production. An important component is missing. [0003] The existing plug valves used for industrial oil production have certain disadvantages in use. First, the industrial oil contains certain sediments and sundries, which are easily adsorbed on the inner wall of the plug valve and are not easy to clean. Valve blockage reduces the service life of the plug valve. Secondly, the valve body and the valve cover are connected by fixing bolts and fixing nuts. Moisture in the air can easily enter the bolt holes and inside the fi...
