Specific embodiment
It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this Utility model.
Referring to figs. 1 to Fig. 5, an a kind of embodiment of the ball valve of good sealing effect of the present utility model, including valve body are proposed 100th, valve element 200, bonnet 300, stem structure.
Valve body 100 is provided with valve pocket 101, and in valve pocket 101, valve element 200 is in valve pocket 101 in valve body 100 for valve element 200 Heart line rotates to realize the purpose that ball valve is opened, closed.Valve body 100 is provided with and stem structure in the position corresponding position of valve element 200 The post holes being adapted, stem structure is interspersed in post holes and one end and the linkage other end of valve element 200 extend to valve body 100 it is outer and with Handle or YE are fixedly connected, and ball valve switch, operation side can be quickly and easily controlled by handle or YE Just and simply.
Stem structure include be embedded in post holes axis 401, be set on axis 401 and be located at post holes in close The filler 402 of envelope effect, the compensation leakage-proof ring for being sheathed in axis 401 and being located on the lower surface of filler 402, compensate leakage-proof ring phase It is butted between axis 401 and post holes madial wall and have compensation, anti-leakage function, compensation leakage-proof ring to be set to V-type spring-compensating Leakage-proof ring.Compensate the sealing lip 403 that leakage-proof ring is provided with annular opening groove including lower surface, the V-type being embedded in annular opening groove Spring 404, V-type spring 404 is squeezed, and power is bigger, and the expansionary force of crush seal lip 403 is bigger outwardly, while V-type spring 404 is forever Long for sealing lip 403 provides elastic force.
In the present embodiment, being arranged with axis 401 can have the sirloin pressure plate structure 500 of pressuring action to filler 402.
Sealing lip 403 is made up of elastomeric material, and elastomeric material has Acclimation temperature wide, sealing, insulating properties etc. good special Property, and high temperature resistant, it is wear-resisting, it is few by external interference, it is preferable preventing water leakage, seal member, sealing lip 403 plays sealing anti-leak Effect, it is and wear-resisting.V-type spring 404 is made up of stainless steel material, and wear resistant corrosion resistant is durable in use.
The utility model ball valve, valve body 100 is provided with the post holes for being passed through for axis 401 and being linked with valve element 200, axis 401 There is gap through the lateral wall of axis during post holes 401 and post holes madial wall, for anti-fluid is directly leaked out from gap And make ball valve occur seepage accident, being arranged with axis 401 has the filler 402 of sealing effectiveness to gap, filler 402 by The soft sealing materials such as PTFE are made, and can compress filler 402 by sirloin pressure plate structure 500 makes the extrusion of filler 402 and swollen It is swollen to be supported in gap, fabulous fluid proof seal effect is played, but rotated for a long time due to axis 401 or frequency of use increase, Filler 402 is susceptible to abrasion because of rotation, and frayed place can produce gap, and pipeline fluid can be from filler 402 and axis Gap position between 401 directly leaks out, and to avoid fluid from being leaked out from gap, the utility model is in axis 401 On be arranged a compensation leakage-proof ring being adapted with post holes, compensation leakage-proof ring compensates leakage-proof ring located at the lower position of filler 402 V-type spring-compensating leakage-proof ring is set to, including lower surface is provided with the sealing lip 403 of annular opening groove, is embedded at annular opening groove Interior V-type spring 404, compensation leakage-proof ring is arranged on axis 401 and is located in post holes, that is, compensate leakage-proof ring and be located at axis 401 And post holes between and by post holes extruding force and axis 401 inwardly extruding force outwardly, the opposite extruding of post holes and axis 401 Act on and the V-type spring 404 being embedded in annular opening groove is squeezed and the tension force of extroversion is formed, promote sealing lip 403 tight It is closely connected to compensate for the gap between axis 401 and post holes together on the madial wall of post holes and the lateral wall of axis 401, while Because V-type spring 404 is forever for sealing lip 403 provides elastic force, that is, compensate for axis 401 and compensate produced by leakage-proof ring abrasion Bad gap, effectively makes up the abrasion of sealing lip 403 and the bias of axis 401 so as to reach permanent sealing effectiveness, it is ensured that in Axle 401 is vertically fixed on valve body 100, ball valve can normal switch, simple structure is practical and convenient, and post holes and axis 401 it Between it is bigger to compensating the extruding force of leakage-proof ring, can be more the accumulation of energy of V-type spring 404, the expansionary force outwardly of V-type spring 404 is bigger, Fitted between sealing lip 403 and post holes madial wall, sealing lip 403 and the lateral wall of axis 401 more abundant, fluid proof seal effect More preferably and permanent, simple structure is reasonable in design, effectively the service life of extension ball valve, reduces maintenance probability, it is ensured that industry sets Standby normal production.Therefore, ball valve of the present utility model, realizes simple structure, reasonable in design, practical, long service life, The beneficial effect such as fluid proof seal effect is good.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, The equivalent structure transformation that every utilization the utility model specification and accompanying drawing content are made, or directly or indirectly it is used in other phases The technical field of pass, is similarly included in scope of patent protection of the present utility model.
