Abstract

The invention belongs to the technical field of pipeline engineering and particularly relates to a rapid blind plate switching device which comprises a blind plate 1, a connection support frame I 2, aconnection support frame II 3, a sealing seat 4, a driving nut 5, a driving rod 6, a sealing element I 7, a sealing element II 8, a hand wheel 9, an indicator board 10, a baffle plate 11, a retainingring 12, a handle 13, a rolling ring 14, a support ring 15 and a driving support table 16. The rapid blind plate switching device, provided by the invention, can completely replace a 8-shaped blind plate and can shorten the entire operating man-hour to the ignored degree compared with the switching time of the 8-shaped blind plate, so that the production efficiency is improved, the leakage rate of a medium is reduced, the environmental pollution is reduced and the staff safety is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline engineering, and in particular relates to a fast switching device for a blind plate. Background technique [0002] In industries such as petroleum, chemical industry, and offshore platforms, blind plates are used as a reliable means of isolation to completely separate media and prevent production from being affected or even accidents due to lax shut-off valves. The process of blind switching of the blind plate is cumbersome, time-consuming and labor-intensive. Each switch needs to loosen the bolts, pry open the pipe, insert the blind plate, install the winding pad, and tighten the bolts. The longer the switching time of the blind plate, the longer the parking time, resulting in reduced production time and affecting the efficiency; when the medium in the pipeline is poisonous, the workers are still in danger of poisoning, so it is required to complete the work as soon as possible. [0003] Due t...
