Abstract

An expander of a pipeline flange comprises a screw rod, support frames, a nut, a left flange, a right flange and a stop lever, wherein the two support frames are symmetrically fixed at two sides of the nut, the stop lever penetrates through bolt holes of the left flange and the right flange, the left end of the stop lever is fixed with the leg portion of the support frame arranged at the left side, the right end of the stop lever is fixed with the leg portion of the support frame arranged at the right side, external threads of the screw rod are matched with internal threads of the nut in a screwed mode, and the lower portion taper of the screw rod inserts between the left flange and the right flange. The distance between the left flange and the right flange is enabled to be increased by rotation of the screw rod, and a cushion between the left flange and the right flange is taken out and replaced with a new cushion. Therefore, the expander of the pipeline flange has the advantages that the flange cushion can be conveniently and rapidly replaced, the labor intensity of workers is low, the working efficiency is high, the working period is short, the idling period of the pipeline is short, the flanges cannot be damaged, remarkable economic benefits are provided.

Description

The pipeline flange spreader
Technical field
The utility model is the equipment that Oilfield Pipelines is safeguarded usefulness, is a kind of pipeline flange spreader.
Background technology
The flange that will adopt that the oil field surface line is connected with connects, mat between two ring flanges of flange needs often to change, and owing to the gap between two ring flanges is little, the mat between the ring flange is difficult to take out, the distance that needs to increase between the two could be taken out it, the way that increases distance between the two at present is to prize ring flange with crowbar, and this way labour intensity is big, inefficiency, long in time limit, the pipeline off-time is long, also damages ring flange easily, causes economic loss.
Summary of the invention
The purpose of this utility model provides a kind of pipeline flange spreader, and it is convenient, fast to make it change the flange mat, and labour intensity is little, high efficiency, and the duration is short, and the pipeline off-time is short, increases economic efficiency.
The purpose of this utility model is achieved in that and comprises screw rod, support, nut, left flange, right flange, pin, two support symmetries are fixed on the both sides of nut, pin passes the bolt hole of left flange, right flange, the shank of the left end of pin and the support on the left side is fixed, the shank of the right-hand member of pin and the support on the right is fixed, the external screw thread of screw rod and the internal thread of nut screw, and the lower taper of screw rod is inserted between left flange, the right flange.
The beneficial effects of the utility model are: rotary screw just can make the distance between left flange, the right flange increase, and between the two mat is taken out more renew mat.Therefore, the utility model replacing flange mat is convenient, fast, and labor strength is low, high efficiency, and the duration is short, and the pipeline off-time is short, does not damage flange, has remarkable economic efficiency.
Description of drawings
Accompanying drawing is the installation diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
As seen from the figure, embodiment of the present utility model comprises screw rod 1, support 2, nut 3, left flange 4, right flange 5, pin 6, two support 2 symmetries are fixed on the both sides of nut 3, pin 6 passes the bolt hole of left flange 4, right flange 5, the shank of the left end of pin 6 and the support on the left side 2 is fixed, the shank of the right-hand member of pin 6 and the support on the right 2 is fixed, and the internal thread of the external screw thread of screw rod 1 and nut 3 screws, and the lower taper of screw rod 1 is inserted between left flange 4, the right flange 5.
Pin 6 can not rotate after being through in the bolt hole of left flange 4, right flange 5, support 2 also just can not rotate, nut 3 also just can not rotate, rotary screw 1, screw rod 1 will be walked downwards while rotating, the taper of screw rod 1 bottom produces radial load to left flange 4, right flange 5, and the distance between left flange 4, the right flange 5 is increased, and mat can take out replacing.
