The utility model discloses technical scheme's a sealed ball valve, rational in infrastructure, cheap phenomenon can not appear in sealing washer in the course of the work, the case direct with ball valve body case contact, the friction reduces, combines sealing washer and spring, has avoided the sealing washer to receive the huge extrusion force that comes from the case for a long time, avoids the sealing washer to warp, lose elasticity, guarantees that the sealing washer can long -term work, the life of extension sealing washer strengthens the sealing performance of ball valve.
Description
Technical field
The utility model belongs to ball valve field, relates to a kind of seal ball-valve in particular.
Background technique
In prior art, ball valve mainly comprises housing, valve road, valve pocket, spool, valve core channel and seal ring, here seal ring is mainly arranged on end, valve road, and with spool close contact, form a Ge Yifa road, the runner of seal ring and valve core channel composition, utilize housing to be compressed with seal ring by spool to contact, make when spool works, seal ring connects valve core channel and valve road, when spool does not work, seal ring seals up spool sphere, liquid in valve road is avoided to overflow through spool sphere, here seal ring is squeezed for a long time, very easily produce expendable distortion, ball valve will be caused like this not seal, need the replacing carrying out seal ring.
Model utility content
The purpose of this utility model is to provide a kind of seal ball-valve, this seal ball-valve is to facilitate the friction reduced between spool and ball valve shell, on the other hand the crush seal between seal ring and spool is set to automatically to regulate shape, reduce the extruding force between seal ring and spool, avoid seal ring to be squeezed for a long time and cause irrecoverability to be out of shape, extending the working life of seal ring.
A kind of seal ball-valve of technical solutions of the utility model, comprise ball valve shell, cylindric valve road, spherical valve pocket, spherical valve core, described cylindric valve road outer installment has cylindrical cavity, spring is provided with in described cylindrical cavity, described spring is connected with seal ring near spherical valve core end, described seal ring contacts with spherical valve core, is provided with rubber cushion blocks in described spherical valve pocket, described rubber cushion blocks parcel spherical valve core.
Preferably, described seal ring is in cylindric, and described cylindrical seal ring one end to be placed in cylindrical cavity and to be connected with spring, and the other end is placed in cylindrical cavity outside and contacts with spherical valve core.
Preferably, described cylindrical seal ring external diameter and cylindrical cavity external diameter adapt, and the internal diameter of cylindrical internal diameter of the seal ring and cylindrical cavity adapts, and the end surface thickness that the thickness of described cylindrical seal ring and spherical valve core are provided with passage adapts.
Preferably, described cylindric valve road is end face one near spherical valve core end, and described cylindrical cavity cylindrical is end face two near spherical valve core end, and described end face one comparatively end face two is far away apart from spherical valve core.
Preferably, described spring is cylindrical spring, and it is outside that described cylindrical spring is socketed on cylindric valve road.
A kind of seal ball-valve of technical solutions of the utility model, at valve road outer installment cylindrical cavity, and spring and seal ring are set in turn in cylindrical cavity, be convenient to the location of spring and seal ring like this and fix, effectively avoid seal ring and occur cheap phenomenon in the course of the work, seal ring only can be moved on valve road axial direction, ensure that the integrally-built stability of ball valve.
A kind of seal ball-valve of technical solutions of the utility model, change the structure that seal ring is only set in prior art, and spring is added in seal ring end, utilize the elasticity of spring, trace, the position of automatic change seal ring, extruding force between automatic change seal ring and spool, effectively avoid seal ring be subject to for a long time from the larger extruding force of spool and produce the distortion that can not recover, loss of seal effect, the design of this seal ring and spring, automatically according to the position of the position adjustment seal ring of spool, never adjustment seal ring is subject to the plus-pressure from spool, the extruding force that seal ring is subject to reduces, seal ring can keep elasticity for a long time, good sealing effect, long service life.
A kind of seal ball-valve of technical solutions of the utility model, arranges the rubber cushion blocks that can wrap spool in valve pocket, avoids carrying out direct friction between spool and ball valve shell, and the ball valve surface abrasion caused, the defect of ball valve reduction in working life.
The utility model technology beneficial effect:
A kind of seal ball-valve of technical solutions of the utility model, rational in infrastructure, seal ring there will not be cheap phenomenon in the course of the work, and spool does not directly contact with ball valve shell, and friction reduces, seal ring and spring are combined, avoid the huge extruding force that seal ring is subject to from spool for a long time, avoid sealed ring deformation, follow the string, ensure the work that seal ring can be long-term, extend the working life of seal ring, strengthen the sealability of ball valve.
