Description
Technical field
The utility model belongs to nuclear power station maintenance technique field, and in particular to one kind is used for parallel gate plate valve sealing surface blue oil
Experimental rig.
Background technique
Certain nuclear power unit largely uses double parallel slide valve as containment isolating valve, in double parallel slide valve maintenance process
It needs the sealing surface to flashboard and valve seat to grind, needs to carry out blue oil test after grinding.
It, cannot be as wedge-shaped slide valve by two flashboards one since double parallel flashboard valve arrangement is different from wedge-shaped slide valve
Blue oil test is carried out with valve seat is fallen into.Double parallel slide valve now used by the method for blue oil test be that flashboard is smeared into blue oil
Flashboard is hung in inside valve chamber afterwards, manually pushes flashboard to be close to valve seat and carries out blue oil contact.Due to not having guiding device, flashboard exists
Free Slosh inside valve chamber manually pushes flashboard to carry out blue oil test and is difficult once success, and generally requiring test of many times could protect
Demonstrate,prove the contact of sealing surface blue oil.There are bothersome laborious, blue oil test's situations of low quality.Therefore need to design a kind of special tool
Tool, be used for double parallel slide valve blue oil test, with faced when solving double parallel slide valve blue oil test can not centering, it is bothersome to take
Power, the not high problem of repair quality.
Summary of the invention
The technical issues of the utility model solves:
In view of the deficiencies of the prior art, the utility model provides a kind of for parallel gate plate valve sealing surface blue oil test dress
Set, faced when being able to solve double parallel slide valve blue oil test can not centering, bothersome laborious, the not high problem of repair quality.
The technical solution adopted in the utility model:
One kind being used for parallel gate plate valve sealing surface blue oil test device, including guide ring, lock-screw, is provided on guide ring
Guide groove, lock-screw are symmetrically installed on guide ring centered on guide groove.
The internal diameter of the guide ring is slightly larger than flashboard internal diameter.
When installation, by guiding coollar on valve seat, while sealing surface of seat being made to be higher than the interior step of guide ring, will be oriented to
Guide ring is symmetrically mounted on valve seat right above being placed in using lock-screw by the guide groove on ring top.
The utility model has the beneficial effects that
(1) provided by the utility model a kind of for parallel gate plate valve sealing surface blue oil test device, structure is simple, makes
With conveniently；
(2) flashboard is oriented to problem when the utility model can effectively solve the problem that parallel gate plate valve sealing surface blue oil test, improves
Blue oil test's quality.
Detailed description of the invention
Fig. 1 is provided by the utility model a kind of for parallel gate plate valve sealing surface blue oil test apparatus structure schematic diagram；
Fig. 2 is guide ring sectional view；
In figure: 1- guide ring, 2- lock-screw.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, it is provided by the utility model a kind of for parallel gate plate valve sealing surface blue oil test device, including lead
To ring 1, lock-screw 2, guide groove is provided on guide ring 1, lock-screw 2 is symmetrically installed on guiding centered on guide groove
On ring 1, the internal diameter of guide ring is slightly larger than flashboard internal diameter.
The concrete operation method of the utility model are as follows:
When using a kind of installation for parallel gate plate valve sealing surface blue oil test's device provided by the utility model, it will be oriented to
1 set of ring on valve seat, while make sealing surface of seat be higher than guide ring 1 interior step, the guide groove on 1 top of guide ring is placed in
The installation of the present apparatus is completed using lock-screw 2 symmetrically by 1 place valve seat of guide ring in surface.
Using provided by the utility model a kind of for parallel gate plate valve sealing surface blue oil test device, progress blue oil test
When, after the installation for as above completing the present apparatus, gate sealing surface is smeared into blue oil, flashboard is sling using hanging ring and is put into valve chamber, will be hung
Ring slides into 1 inside of guide ring to the top guide groove of positive guide ring 1, while by flashboard, flashboard be in place after to preceding promotion lock
Plate makes its sealing surface and valve base sealing face contact, after pull out flashboard, flashboard is taken out, complete blue oil test.
The utility model is explained in detail above in conjunction with drawings and examples, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of make a variety of changes.The prior art can be used in the content being not described in detail in the utility model.
