Pipeline transportation equipment for natural gas

Abstract

The invention relates to pipeline transportation equipment for natural gas. The pipeline transportation equipment comprises a valve body, a hydraulic cylinder and two connecting pipes, wherein the hydraulic cylinder is vertically arranged at the top of the inside of the valve body; the two connecting pipes are separately and horizontally arranged on the two sides of the valve body; two filtering perforated pipes communicate through the valve body; the two connecting pipes are coaxially arranged; the hydraulic cylinder is positioned above the connecting pipes; the valve body is provided with two sealing mechanisms and two filtering mechanisms; the sealing mechanisms and the filtering mechanisms are in one-to-one correspondence with the connecting pipes; and the sealing mechanisms comprise supporting blocks, push rods, connecting rods, extrusion plates, air bags, supporting disks and supporting assemblies. According to the pipeline transportation equipment for the natural gas, the sealing performance is improved through the sealing mechanisms, and the sealing effect is prevented from being affected by gaps generated by wear and tear. Moreover, the function of filtering out impurities in the natural gas is achieved through the filtering mechanisms.

Description

technical field [0001] The invention relates to the field of pipeline transportation, in particular to pipeline transportation equipment for natural gas. Background technique [0002] Pipeline transportation is a long-distance transportation method of transporting liquid and gas materials using pipelines as a means of transportation. It is a transportation method that specifically transports petroleum, coal and chemical products from the production site to the market. It is the backbone of the unified transportation network. special components. [0003] When natural gas is transported by pipeline, the opening and closing of the pipeline is mostly controlled by the flapper valve. The flapper valve is also called the manual knife gate valve. During the use of the existing flapper valve, the valve body and the valve plate will be damaged after long-term wear It affects the sealing performance and reduces the practicability. Not only that, in order to prevent impurities from cl...

[0003] When natural gas is transported by pipeline, the opening and closing of the pipeline is mostly controlled by the flapper valve. The flapper valve is also called the manual knife gate valve. During the use of the existing flapper valve, the valve body and the valve plate will be damaged after long-term wear It affects the sealing performance and reduces the practicability. Not only that, in order to prevent impurities from clogging the valve body, the existing flapper valves are equipped with filter screens, and when the impurities trapped on the filter screen gather together, the filter screen will be blocked, reducing the Practicality
