A pipe sealing plate

Abstract

The invention discloses a pipeline sealing plate comprising a disc. The upper edge of the disc is provided with a trapezoidal neck. A bearing surface is arranged on each of the front and back surfaces of the disc while two semicircular buffer recess areas are formed at the center of each bearing surface; meanwhile, a horizontal retainer plate is mounted between each two semicircular buffer recess areas and both sides of the horizontal retainer plate are connected with the edges of the disc respectively; seal strips are disposed at the two edge joints respectively, and a rotary handle is disposed on the outer surface of each horizontal retainer plate. The pipeline sealing plate has the advantages that the buffer recess areas are formed at the center of the bearing surfaces of the disc and used with the horizontal retainer plates, and the stopping and buffering effects are great; when liquid oil impacts to the buffer recesses, turbulent vortexes form, so that the impact of oil upon the valve plate is reduced; the contour of the pipeline sealing plate matches with the section of an oil pipeline, so that product sealing performance is further improved.

Description

technical field [0001] The invention relates to an oil pipeline fitting, in particular to a pipeline sealing plate. Background technique [0002] Pipeline transportation is a long-distance transportation method of 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. When using pipelines for oil transportation, various valves need to be used on some high-pressure pipelines to obtain functions such as cut-off and discharge to achieve different purposes, but the valves in some parts are only used to block the flow of oil. In this case, relatively simple and low-cost gates, compression plates and other structures can be used. There are many problems with the traditional ram, for example: the cross section is generally square or rectangular, the ram...

AI Technical Summary

Problems solved by technology

There are many problems with the traditional ram, for example: the cross section is generally square or rectangular, the ram and the section of the oil pipeline cannot be well matched, so the blocking position is prone to deviation, and the blocking effect is poor; at the same time, due to the oil flow When the speed and strength are relatively high, when impacting on a relatively flat ram surface, the ram will bear a large oil pressure, which may sometimes cause safety accidents
