Abstract
The utility model relates to a jacking-opening device for replacing asbestos pad of flange, which consists of a jackscrew, an upper flange, a lower flange, a bolt hole and a flange central hole, and is characterized in that two jackscrew holes are symmetrically arranged between the flange bolt hole, the jackscrew hole is provided with two jackscrews, and the two jackscrews are jacked below the lower flange. The utility model solves the problems of the prior art that the asbestos pad between the flanges is difficult to replace. As long as the two jackscrews are simultaneously screwed, the upperand the lower flanges can be opened, so the asbestos pad is convenient to take out or fit in, the time and the labor can be saved, and the replacement speed and the replacement efficiency of the asbestos pad can be improved.
Description
One, technical field
The utility model relates to a kind of instrument that backs down adpting flange in the technological process, specifically a kind of replacing flange asbestos mat opener.
Two, background technology
Flange is the critical piece that connects technological process, at the normal connecting line in service of technological process, connect valve and be connected miscellaneous equipment, asbestos mat between the flange is often changed, changing the asbestos pad period of the day from 11 p.m. to 1 a.m because technical flow design compact, that blocks between two flanges is tighter, pry open flange and change asbestos mat special charges strength, all be to pry open with crowbar, the slit of prying open is very little, and the cleaning of cleaning asbestos mat vestiges is unclean, it is also relatively more difficult to place the asbestos mat, do not do a good job with regard to handle grip inside, the success rate of changing the asbestos mat is very low, and handy three people cooperation of replacing asbestos is wasted time and energy.
Three, summary of the invention
The purpose of this utility model provides a kind of replacing flange asbestos mat opener, solves the problem that above-mentioned prior art is changed flange asbestos mat difficulty.
Technical scheme of the present utility model realizes in the following manner:
The utility model is by jackscrew, upper and lower ring flange, and bolt hole and ring flange centre bore are formed, and it is characterized in that being arranged with between the upper flange plate bolt hole two top wire holes, and top wire hole is provided with two jackscrews, and two jackscrew roof pressures are on lower flange.
The utility model has solved the problem of the asbestos mat difficulty between the replacing flange that above-mentioned prior art exists, as long as twisting two jackscrews simultaneously will back down going up lower flange, can take out the asbestos mat or put into freely, time saving and energy saving, improved speed and the efficient of changing the asbestos mat.
Four, description of drawings
Accompanying drawing structural representation of the present utility model
1-jackscrew 2-upper flange plate 3-bolt hole 4-flange center hole 5-lower flange among the figure
Five, the specific embodiment:
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with the explanation accompanying drawing:
The utility model is by jackscrew 1, upper and lower ring flange 2,5, and bolt hole 3 and ring flange centre bore 4 are formed, and it is characterized in that being arranged with between the upper flange plate bolt hole two top wire holes, and top wire hole is provided with two jackscrews, and two jackscrew roof pressures are on lower flange.
The utility model can be transformed on ring flange existing, promptly existing with the bolt hole of upper flange plate or lower flange between with arch silk machine arch on the top wire hole of two symmetries, mix jackscrew and get final product, also can be directly in manufacturer production.
Directly twist jackscrew 1 when using the utility model last lower flange 2.5 is backed down, take out the asbestos mat of changing, change the neolite cotton pad and get final product, when twisting jackscrew, must twist jackscrew simultaneously, make centre bore 4 alignment of the last lower flange that backs down, prevent from asbestos pad is pressed partially, damage by pressure and cause sealing place leakage.
