Abstract
It the utility model is related to a kind of aid for nuclear power station screw-type valve cap of valve folding, to coordinate the bonnet of spanner folding screw-type valve, the aid is in boss-shaped structure, including coordinate with spanner six side's plush coppers, being enclosed on screw-type valve york piece and the sleeve of clamping, six described side's plush copper centers are opened up through the axis hole of valve handle axle, a plurality of vertical groove is offered in described sleeve.Compared with prior art, the utility model has the advantages that raising maintenance process standard, applied widely, safety coefficient is high.
Description
Technical field
A kind of instrument is the utility model is related to, more particularly, to a kind of for the auxiliary of nuclear power station screw-type valve cap of valve folding
Assistant engineer has.
Background technology
Many screw-type bonnet stop valves are housed in nuclear island of nuclear power station process system, as shown in drawings；This stop valve
Mostly critical level equipment, belong to forced seal formula valve.During such valve breakdown maintenance, the method used at present is to use
Pipe vice or spanner with belt unscrew valve, do not have suitable instrument to carry out torque fastening in valve recovers assembling process, this
Problems be present in kind method for maintaining：
(1) for indivedual valves due to expanding with heat and contract with cold, the frictional force of screw thread is too big, can not be direct using pipe vice or spanner with belt
Valve is disintegrated, forces dismounting that device damage, tool damage may be caused to use.
(2) according to such a model maintenance of valve regulatory requirements of nuclear power station, to ensure that valve does not leak outside, recover in valve
Moment requirement during assembling, pipe vice or spanner with belt can not all be completed to play the requirement of torque, and many power stations all do not have at present
The maintenance torque spanner of such valve.
Utility model content
The purpose of this utility model is exactly to be repaired to provide a kind of improve the defects of overcoming above-mentioned prior art to exist
Technological standards, the aid for nuclear power station screw-type valve cap of valve folding applied widely, safety coefficient is high.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of aid for nuclear power station screw-type valve cap of valve folding, to coordinate spanner folding screw-type valve
Bonnet, the aid is in boss-shaped structure, including coordinate with spanner six side's plush coppers, being enclosed on screw-type valve york piece
Upper and clamping sleeve, six described side's plush copper centers are opened up through the axis hole of valve handle axle, to be opened in described sleeve
Provided with a plurality of vertical groove.
Six described side's plush coppers are outer six sides plush copper.
Collet head is also arranged with outside six described side's plush coppers, described collet head is connected with six side's plush coppers to apply
Reinforce square.
Described spanner is double offset ring spanner or box spanner.
Six described side's plush coppers and sleeve are made of 20 steel.
Described vertical groove is provided with 4.
Compared with prior art, the utility model has advantages below：
First, maintenance process standard is improved：When in use, the sleeve of this aid is set on valve york piece and passed through
Groove clamping, torque is applied to outer-hexagonal plush copper by spanner, so as to complete to close or open valve cap of valve, meets that valve opens dress
When torque fastening requirements.
2nd, it is applied widely：The utility model can make according to live physical device size and torque requirement, can be equipped with
The torque spanner of different model, applicability are wider.
3rd, safety coefficient is high：It is middle compared with prior art to use pipe vice and spanner with belt disintegration valve safety and reliability, energy
The generation of enough situations such as effectively preventing torque from applying deficiency or causing worker injuries.
Brief description of the drawings
Fig. 1 is that the utility model assembles using renderings.
Fig. 2 is structural representation of the present utility model.
Wherein, 1, six side's plush copper, 2, sleeve, 3, axis hole, 4, groove, 5, collet head, 6, spanner, 7, york piece.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in figure 1, the utility model provide it is a kind of facilitate screw-type bonnet stop valve disintegrate and carry out torque fastening
Aid, the utility model is six sides of " convex " type-telescoping structure, coordinates plum blossom open-end wrench or torque spanner to use
The utility model is made using 20 steel by machining, is machined with 4 grooves 4 inside sleeve 2, is enclosed on valve york piece
On 7, it can be connected and be fitted close with valve york piece 7；
Plush copper of the present utility model is processed into hexagon, for coordinating plum blossom open-end wrench or torque spanner to use, and
Different dimensions patterns can be dimensioned to according to the valve The concrete specification repaired.
As shown in Fig. 2 application method of the present utility model is as follows：
During field maintenance screw-type bonnet stop valve, first valve handle is removed, the loading tool is sleeved on valve yoke
On frame 7, coordinate corresponding size spanner 6 (plum blossom open-end wrench or box spanner), you can easily realize screw-type bonnet stop valve
Disintegrate and dismantle, coordinate torque spanner that torque fastening requirements can be achieved when returning dress valve.
