Eccentric half-ball valve and gate valve are the valves for belonging to a type together, and difference is that its closure member is a spheroid, spheroid Rotated around valve body center line, come a kind of valve for reaching unlatching, closing purpose.Ball valve is mainly used to cut in pipeline Disconnected, distribution and the flow direction for changing medium.Two-chip type ball valve, three-flat ball valve is the valve being widely used in recent years.Partially Heart semisphere valve is a kind of ball valve classification of modern, and it has some exclusive superiority of self structure, such as simple in construction, body Product is small, lightweight.Being widely used in sewage disposal, paper pulp, aluminum oxide, urban heating heat supply etc. needs tight closed occasion; Suitable for the control of power plant, water sluice or gaseous state conveyance conduit.
Eccentric half-ball valve is a kind of relatively new type ball valve classification, and it has some exclusive superiority of self structure, No friction is such as switched, seals not easy to wear, opens and closes torque small.The specification of matched somebody with somebody actuator can so be reduced.It is equipped with many revolution electricity Dynamic executing agency, can be achieved the regulation to medium and featuring rigid cutting-off.It is widely used in the requirement such as oil, chemical industry, urban water supply and sewerage The operating mode strictly cut off.Sealing pair on the valve element and valve seat of current semisphere valve easily weares and teares and causes sealing not close.
Utility model content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency that there is provided a kind of eccentric semi-spherical Valve.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of eccentric half-ball valve, including valve body and the hemisphere valve element being arranged in valve body, hemisphere valve element bottom passes through lower valve Axle is connected to valve body, and hemisphere valve element top is provided with Lower shaft sleeve, valve by upper valve shaft connection valve body between lower valve shaft and hemisphere valve element Body top is provided with the bonnet for being sheathed on valve shaft, Upper shaft sleeve is provided between upper valve shaft and bonnet, valve body lower portion, which is provided with, to be used to cover envelope The bottom of lower valve shaft, the hemisphere valve element sphere side is provided with spherical crown, and spherical crown moulds wadding provided with fluorine, and valve body is provided with and spherical crown The valve seat being engaged, the valve seat moulds wadding with spherical crown relative position provided with fluorine, and the valve seat is fixed by collar and positioning retainer ring Position, is provided with elastic washer between valve seat side and valve body, and spring is provided between valve seat and collar.
The Lower shaft sleeve and the Upper shaft sleeve are made up of nano-graphene material.Nano-graphene material thermal conductivity and wear-resisting Property is all very good, adds the service life of valve shaft and lower valve shaft.
The spherical crown is cast by chromansil cast steel.
The valve seat is cast by high molybdenum alloy cast steel.
Axle envelope set is additionally provided between the upper valve shaft and bonnet, between the axle envelope set and bonnet, axle envelope set and upper valve shaft Between be provided with elastic washer, between the lower valve shaft and valve body be provided with elastic washer.Elastic washer ensures upper valve shaft, lower valve shaft work Toughness when making, it is to avoid abrasion that long-term rotation is caused and sideslip.
The elastic washer is made up of nitrile rubber.
The beneficial effects of the utility model are:Set fluorine to mould wadding as sealing pair on valve seat and spherical crown, greatly enhance The wearability and corrosion resistance of sealing pair, and when fluorine modeling wadding has mild wear, spring can extend has forward one to valve seat Fixed propulsion compensation, so that the fluorine modeling wadding on valve seat continues to be fitted close with the fluorine modeling wadding on spherical crown forward, it is ensured that The normal work of valve.
