Abstract
The utility model relates to a plane superhigh pressure is from sealing system, can effectively solve the problem that the sealing device of current superhigh pressure system can not satisfy the use needs, and the technical scheme of its solution is, including valve body and case, be equipped with the case on the inherent valve opening of valve body, there is the end cover on the valve body on the case right side, and the case right-hand member passes the end cover, is equipped with the spring on the case between case and the end cover, has a plurality of semi-circular sealing rings on the case left end face, the utility model discloses simple structure, unique is the innovation on the superhigh pressure sealing device.
Description
Technical field
The utility model relates to sealing and leakage-proof device, particularly a kind of plane ultrahigh pressure selfsealings system.
Background technique
Superhigh pressure technique still is in the starting stage in China; The research of its hermetic unit plays an important role to the development of superhigh pressure technique; Because traditional sealing means can only use under usual pressure; Its structure can't guarantee Seal of Equipment property under extra high voltage system, and for guaranteeing the normal safe operation of extra high voltage system, improvement on the extra high voltage system seal arrangement and innovation are the problems that needs solution.
Summary of the invention
To above-mentioned situation, for overcoming the defective of existing technology, the purpose of the utility model just provides a kind of plane ultrahigh pressure selfsealings system, and the seal arrangement that can effectively solve existing extra high voltage system can not satisfy the problem of use needs.
The technological scheme of its solution is, comprises valve body and spool, on the inherent valve opening of valve body spool is housed; There is end cap on the spool right side on valve body; The spool right-hand member passes end cap, and spring is housed on spool between spool and the end cap, and a plurality of semicircle seal rings are arranged on the spool left side.
The utility model is simple in structure, unique, is the innovation on the superhigh pressure sealing device.
Description of drawings
Fig. 1 is the main pseudosection of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain.
Provided by Fig. 1, the utility model comprises valve body and spool, on the valve body 1 inherent valve opening 6 spool 2 is housed; There is end cap 3 on spool 2 right sides on valve body 1; Spool 2 right-hand members pass end cap 3, and spring 4 is housed on spool 2 between spool 2 and the end cap 3, and a plurality of semicircle seal rings 5 are arranged on spool 2 left sides.
In order to guarantee using effect and easy to maintenance, said end cap 3 is fixed on the valve body 1 through screw 7.
Between the said adjacent semicircle seal ring 5 is plane structure, and adjacent two halves circular seal ring 5 top lines are parallel with spool 2 right sides, guarantees that at least one seal ring seals fully.
When the utility model used, under the situation of not working, spool 2 received the thrust of spring 4, valve closing; Under the situation of work, highly pressurised liquid gets into from the left side of the utility model, and the resistance that promotion spool 2 overcomes spring 4 moves right; Valve opening 6 is opened, and liquid gets into high-pressure chamber through end cap 3, when high-voltage power supply stops voltage supply; Spool 2 receives the pressure from high-pressure chamber, and spool 2 and valve body 1 are compressed, and the extruding that the semicircle seal ring 5 of spool 2 raisings receives valve body 1 plane produces distortion; Semicircle seal ring 5 and valve body 1 are contacted by line and become face and contact, and finally reach the effect of sealing, have so just formed a kind of selfsealings system; Owing to the working portion of the utility model is by semicircle seal ring 5 the face contact that deformation produce to take place, therefore can reduce the machining accuracy of sealing system, cut down finished cost.
The utility model is simple in structure, unique, and is easy to use, and good sealing effect is the innovation on the ultrahigh pressure self-seal device.
