Lubrication and adjustment valve body

Abstract

The invention discloses a lubrication and adjustment valve body. The lubrication and adjustment valve body comprises a valve main body and a valve seat. The valve main body is arranged in the valve seat. Adjustment bases are arranged on the outer portion of the valve seat. Adjustment bent rods are arranged in the adjustment bases. One end of each adjustment bent rod extends out of the corresponding adjustment base, and the other end of each adjustment bent extends into the valve main body. Compression springs are arranged between the adjustment bent rods and the inner walls of the adjustment bases. An oil storage tank is arranged at the upper end of the valve main body, communicated to the outer portion of the valve main body through an oil guide way and sealed through a sealing cover. An oil leakage film is arranged at the bottom of the oil storage tank. According to the scheme, the adjustment bases are arranged on the outer portion of the valve main body and can adjust the overall pre-tightening force, the oil storage tank is arranged at the upper end of the valve main body, and therefore the valve main body can be conveniently lubricated, lubricating oil can be stored in the oil storage tank through the oil guide way, the valve main body is slowly lubricated by the lubricating oil through the oil leakage film, and the adjustment bases are arranged outside the valve main body and are easy to assemble while the lubricating property in the valve main body is kept.

Description

technical field [0001] The invention relates to a regulating device, in particular to a lubricating regulating valve body. Background technique [0002] Top-entry ball valves are widely used in oil and natural gas pipelines, and in oil extraction, oil refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food and papermaking and other devices. Top-entry ball valves are easy to disassemble on the pipeline and easy to maintain. When the valve fails on the pipeline and needs to be repaired, it is not necessary to disassemble the valve from the pipeline, only the flange bolts and nuts need to be removed, the valve cover and stem assembly are removed from the valve body, and then the ball and seat are taken out Assemblies, the ball and the valve seat can be repaired online, which saves time for maintenance, but there are some disadvantages in the existing lubricated regulating valve body: the spring preload cannot be adjusted and controlled...
