Description

A kind of flange opener

Technical field

The utility model relates to the power tool of changing the flange asbestos washer in oil in the field produces, gas, the water conveyance conduit, is specially a kind of flange opener.

Background technology

Valve is more in oil, gas, the water conveyance conduit valve group, close together, one human crowbar is pried open two relative flanges when changing flange gasket, another people clears up old pad and more renews pad, because crowbar does not have effective fulcrum at flange, crowbar skids easily, so be the operation of a complexity, present above-mentioned operation is very inconvenient, waste time and energy, and has potential safety hazard.

The utility model content

The purpose of this utility model is exactly the defective that exists for prior art, and a kind of simple in structure, easy to operate, the flange opener that can realize fast changing flange gasket and safety and stability is provided.

The concrete technical scheme of the utility model is: comprise the support centralizing bracket, it is the front opening structure that two laminated planks form, and the front end of described support centralizing bracket is provided with corresponding longitudinal hole, is provided with alignment pin in the through hole; The rear portion of described double-deck clamping plate is threaded connection transversely movable jackscrew bar, and jackscrew bar front end is cone.

Such scheme further is improved to:

The nut-welding of described two laminated planks by the rear portion together, and the described jackscrew bar movement that matches with nut.

Described nut and jackscrew bar are two that are set up in parallel.

The utility model compared with prior art has following remarkable result:

1, than an original operator, the manpower and materials in the saving operation of reducing.

2, save the activity duration, operating efficiency is enhanced about more than once.

3, can not skid in the operation, effectively improve the security of operation.
