Abstract
The invention belongs to mechanical assembly technique fields, and in particular to a kind of guide's safety valve valve chamber graphite annulus takes out tool and its operating method, and graphite annulus takes out that tool includes: handle, graphite annulus takes out tool end and graphite annulus takes out tool semicircle groove；The graphite annulus takes out the setting of tool semicircle groove and takes out tool end and handle junction in graphite annulus.The present invention can effectively solve the problem that nuclear power station SEBIM safety valve pilot valve valve chamber graphite annulus takes out difficult problem, and time saving, laborsaving and do not allow easy damaged valve chamber.
Description
Technical field
The invention belongs to mechanical assembly technique fields, and in particular to a kind of guide's safety valve valve chamber graphite annulus take out tool and
Its operating method.
Background technique
SEBIM safety valve is to provide a kind of pilot operated safety valve of overpressure protection for pressure vessel and pressure-bearing pipeline, at present
It is widely used in nuclear power station important system equipment.Structure is complicated for nuclear power station SEBIM safety valve pilot valve, maintenance difficult, guide
Valve valve chamber interior design has graphite-seal ring, which needs to re-replace in valve breakdown maintenance, takes out old
When graphite annulus, since the deeper and old graphite annulus in the position of installation graphite annulus inside pilot valve valve chamber by compressing for a long time,
It is more difficult to be drawn off, valve chamber is easy to damage using conventional tool such as screwdriver etc..
Therefore it needs to design a kind of dedicated unit, is taken out for nuclear power station SEBIM safety valve pilot valve valve chamber graphite annulus.
Summary of the invention
Object of the present invention is to provide a kind of guide's safety valve valve chamber graphite annulus taking-up work in view of the above shortcomings of the prior art
Tool and its operating method, for solving the problems, such as that it is difficult that nuclear power station SEBIM safety valve pilot valve valve chamber graphite annulus takes out.
The technical scheme is that
A kind of L-type structure that guide's safety valve valve chamber graphite annulus taking-up tool is integrally formed, graphite annulus take out kit
Include: handle, graphite annulus take out tool end and graphite annulus takes out tool semicircle groove；The graphite annulus takes out tool semicircle groove
Setting takes out tool end and handle junction in graphite annulus.
The decreased food is 80mm, and handle is stainless steel material.
It is acuter angles that the graphite annulus, which takes out tool end, and sharp angle is 15 °.
The groove diameter that the graphite annulus takes out tool semicircle groove is 2mm, penetrates graphite annulus when graphite annulus takes out tool
When, it is broken that Mo Huan taking-up tool semicircle groove protects the edge of graphite annulus not to be squeezed.
It is 5mm that the graphite annulus, which takes out tool end length,.
The handle is cylindrical structure, handle diameters 2.5mm.
A kind of guide's safety valve valve chamber graphite annulus as mentioned takes out the operating method of tool, includes the following steps:
Step 1: graphite annulus taking-up tool is put in nuclear power station safety full valve pilot valve valve chamber；
Step 2: graphite annulus taking-up tool end is penetrated inside sealing ring, lifts old sealing ring then up, by it
Take out valve chamber.
A kind of guide's safety valve valve chamber graphite annulus designed by the present invention takes out tool and its operating method, and having following has
Beneficial effect: one kind that the present invention designs takes out tool for nuclear power station guide safety valve valve chamber graphite annulus, and structure is simple, uses
It is convenient；It can effectively solve the problem that nuclear power station SEBIM safety valve pilot valve valve chamber graphite annulus takes out difficult problem, and time saving, laborsaving
And easy damaged valve chamber is not allowed.
Detailed description of the invention
Fig. 1 is a kind of guide's safety valve valve chamber graphite annulus taking-up tool construction schematic diagram designed by the present invention；
Fig. 2 is a kind of guide's safety valve valve chamber graphite annulus taking-up tool operation method schematic diagram designed by the present invention；
Wherein, 1-handle；2-graphite annulus take out tool end；3-graphite annulus take out tool semicircle groove；4- safety valve
Pilot valve valve chamber；5- sealing ring.
Specific embodiment
The technology of the present invention is described further below:
As shown in Fig. 1 to 2, a kind of guide's safety valve valve chamber graphite annulus taking-up tool, the L-type structure being integrally formed, stone
It includes: that handle 1, graphite annulus taking-up tool end 2 and graphite annulus take out tool semicircle groove 3 that Mo Huan, which takes out tool,；The graphite
Ring takes out the setting of tool semicircle groove 3 and takes out tool end 2 and 1 junction of handle in graphite annulus.
1 length of handle is 80mm, and handle 1 is stainless steel material.
It is acuter angles that the graphite annulus, which takes out tool end 2, and sharp angle is 15 °.
The groove diameter that the graphite annulus takes out tool semicircle groove 3 is 2mm, penetrates graphite annulus when graphite annulus takes out tool
When, it is broken that Mo Huan taking-up tool semicircle groove 3 protects the edge of graphite annulus not to be squeezed.
It is 5mm that the graphite annulus, which takes out 2 length of tool end,.
The handle 1 is cylindrical structure, and 1 diameter of handle is 2.5mm.
A kind of guide's safety valve valve chamber graphite annulus as mentioned takes out the operating method of tool, includes the following steps:
Step 1: graphite annulus taking-up tool is put in nuclear power station safety full valve pilot valve valve chamber；
Step 2: graphite annulus taking-up tool end 2 being penetrated inside sealing ring 5, lifts old sealing ring 5 then up,
It is drawn off valve chamber.
The present invention is explained in detail above in conjunction with embodiment, but the present invention is not limited to above-described embodiments, at this
