Description

One simply repaiies valve instrument

Technical field

This utility model belongs to oil and gas exploitation technical field, is specifically related to one and simply repaiies valve instrument.

Background technology

Gate valve on oil-field well head device, often due to severe working condition, the most long neglected and in disrepair, the valve rod of valve and Copper nut often becomes rusty extremely, and valve cannot be made to open or close by normal operating handwheel, what is more, will appear from the shape of valve seepage Condition..In this case, prior art is typically all replacing gate valve with pressure, if valve is to close, before replacing valve with pressure, also Valve boring with pressure must be implemented, but in view of this fault, itself be not due to key position (the such as valve plate, valve of gate valve Seat) damage and cause, if so directly changing gate valve, unnecessary cost allowance certainly will be caused, so it is not recommended that the most more Renew valve.

Utility model content

The purpose of this utility model is to provide one simply to repair valve instrument, scarce with overcome above-mentioned prior art to exist Falling into, valve can be keeped in repair in the case of normal operation by this utility model, saves the manpower thing changing new valve Power.

For reaching above-mentioned purpose, this utility model adopts the following technical scheme that

One simply repaiies valve instrument, including being fixed on the clip at valve two ends, clip is fixed with the limit parallel with valve rod Position column, and the centrage of the centrage of two spacing columns and valve rod is generally aligned in the same plane, the free end of two spacing columns Being connected by crossbeam, crossbeam connects the buffer bar for holding out against valve rod.

Further, upper body connecting and has chuck, the two ends of chuck connect respectively and are fastened on two spacing columns On.

Further, chuck is made up of two symmetrical half blocks.

Further, spacing column is provided with the stop nut for regulating crossbeam position with the junction of crossbeam.

Further, crossbeam is provided with screwed hole, and buffer bar is threaded rod, and described buffer bar is by screwed hole with crossbeam even Connect.

Further, screwed hole is arranged on the center of crossbeam.

Further, the centrage of buffer bar and the centrage of valve rod are positioned at same straight line.

Compared with prior art, this utility model has a following useful technique effect:

The corrosion that in valve environment in the wild, various factors causes, and can not normal operation, ensureing normal work Under premise keeping in repair valve the most necessary, valve, in the case of normal operation, is keeped in repair by this utility model, utilizes Simple force structure, when instantaneous pressure changes, because, while loosening or laying down valve stem nut, the athletic meeting of valve rod produces One impulsive force the biggest, in order to avoid valve rod is gone out suddenly, causes the harm to people or thing, and this utility model uses simple Structure, make valve rod in the instantaneous variation that is under pressure the most just by the cushioning effect of buffer bar, under the restriction, Reduce cushion effect slowly, make to move slowly and exit, many parts of the valve stem part of gate valve can be replaced or tie up Repair, it is ensured that can use normally in follow-up work, and reach relevant requirement, save the manpower thing changing new valve Power, and simple in construction, easy to operate, safe and reliable.

Further, by arranging chuck, parallel with valve rod to ensure two spacing columns, so ensure buffer bar with Valve rod center alignment, plays the effect of holding out against.

Further, stop nut is used can to regulate the position of crossbeam, to be applicable to the valve internals of various model more Change maintenance.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in further detail:

Seeing Fig. 1 and Fig. 2, one simply repaiies valve instrument, including the clip 2 being fixed on valve 1 two ends neck or flange, The spacing column 4 parallel with valve rod 8 it is fixed with on clip 2, and the centrage position of the centrage of two spacing columns 4 and valve rod 8 In same plane, the free end of two spacing columns 4 is connected by crossbeam 6, and spacing column 4 is provided with use with the junction of crossbeam 6 In the stop nut 5 of regulation crossbeam 6 position, valve 1 is provided with upper body 10, and upper body 10 is provided with capping 9, upper case Being provided with valve rod 8 in body 10 and capping 9, crossbeam 6 connects the buffer bar 7 for holding out against valve rod 8, the centrage of buffer bar 7 with The centrage of valve rod 8 is positioned at same straight line, and the center of crossbeam 6 is provided with screwed hole, and buffer bar 7 is threaded rod, and buffer bar 7 passes through spiral shell Pit is connected with crossbeam 6, and upper body 10 connects has chuck 3, the two ends of chuck 3 to be connected on two spacing columns 4, Chuck 3 is made up of two symmetrical half blocks.

Below in conjunction with the accompanying drawings implementation process of the present utility model is further described:

During use, first clip 2 is arranged on the valve two ends needing to change accessory, two clips 2 respectively connect A piece spacing column 4；Then installing cervical region crossbeam 6 between spacing column 4, crossbeam 6 can be adjusted to fit by stop nut 5 Work as position；Being arranged in the screwed hole of crossbeam 6 center by buffer bar 7, installation buffer bar bar is for cap, by rotating buffer bar 7 valve rods 8 compressing valve 1, slowly dismantle valve rod, change valve fittings, it is possible in the case of normal operation, to valve Keep in repair, save the manpower and materials changing new valve.
