A petroleum mechanical valve with limit function

Abstract

The invention relates to the technical field of pipeline valves, in particular to a petroleum mechanical valve with a limit function. To the waterproof structure inside the device, the intercepting structure is installed with an oil injection structure for lubricating the device, the valve body is connected with a disassembly structure for disassembling and replacing the device, and the valve body is connected with a limit structure for limiting the intercepting structure. , The valve body is equipped with a pushing structure to avoid the formation of oil deposits; the blocking effect can be achieved through the intercepting structure, the waterproof structure prevents water from entering the interior of the device, the oil filling structure can lubricate the intercepting structure, and the disassembly and assembly structure is convenient When overhauling the device, the working state of the device can be locked through the limiting structure, and the formation of petroleum deposits can be avoided through the pushing structure.

Description

technical field [0001] The invention relates to the technical field of pipeline valves, in particular to a petroleum machinery valve with a limit function. Background technique [0002] In the fluid pipeline system, the valve is the control element. Its main function is to isolate the equipment and the pipeline system, regulate the flow, prevent backflow, regulate and discharge the pressure. The transportation of oil needs to be coordinated through the pipeline and the valve to transport the oil to various places. , Through the valve, the transportation of oil can be regulated in time, and the valve is very important in the transportation of oil. [0003] At present, the valve with the limiting function used in the oil pipeline is usually to limit the screw or the rotating disc. The rotating disc and the screw are exposed to the air for a long time, which is easy to rust, and the rainwater is easy to enter the inside of the device. Ideally, there is no waterproof protection...

AI Technical Summary

Problems solved by technology

[0003] At present, the valves with limit function used in oil pipelines usually limit the position of the screw or the rotating disc. The rotating disc and the screw are exposed to the air for a long time, which is easy to rust, rainwater is easy to enter the interior of the device, and the protection function is not good. Ideal, without waterproof protection between the screw and the rotating disc, it is easy to cause damage to the limit function. When the valve is closed, oil is easy to deposit in the closing groove of the intercepting door, which is not easy to clean and affects the closing of the later valve.
