Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of reasonable in design, good seal performance, service life is long, and performance is excellent
Good disc spring loads automatic compensating ball valve.
Background technology
Used in high-pressure system, ball valve is mostly polyether-ether-ketone or the valve seat of the close material of other hardness at present, and this type of seat material is inclined
Firmly, the highest to each component processing precision prescribed, if machining accuracy does not reaches requirement, the prooving of valve seat during use, can be caused；With
Time general ball valve opening after certain number of times, the prooving of valve seat has exceeded the decrement of valve seal needs, and change can cause leaking,
Sealing property is deteriorated, and service life is shorter.
Therefore, necessary on the basis of prior art, a kind of reasonable in design of design research and development, sealing is high, safety
Property good, service life is long, and the disc spring that has wide range of applications loads automatic compensating ball valve.
Summary of the invention
Goal of the invention: it is an object of the invention to for the deficiencies in the prior art, R & D design one reasonable in design, sealing
Height, security is good, and service life is long, and the disc spring having wide range of applications loads automatic compensating ball valve.
Technical scheme: in order to realize object above, the technical scheme that the present invention takes is as follows:
A kind of disc spring loads automatic compensating ball valve, and it includes: valve body, the support seat being arranged in valve body, is arranged in support seat
Valve seat, the valve ball being arranged on valve seat, support seat back lay disc spring, the two ends of valve body are all screwed with end connector, disc spring position
In supporting in the middle of seat and end connector；
The upper end of valve ball connects valve rod, is provided with filler, filler is provided with packing press ring, valve rod between valve body and valve rod
Upper end is connected with hex nut and handle, is provided with spring washer between hex nut and handle, and valve body top is provided with control and opens
Close the alignment pin of stroke.
Preferably, above-described disc spring loads automatic compensating ball valve, is provided with O between described end connector and valve body
RunddichtringO.
Preferably, above-described disc spring loads automatic compensating ball valve, is provided with between described end connector and support seat
O RunddichtringO.
Disc spring of the present invention loads automatic compensating ball valve, by the ball valve using spring washer to load valve seat, reducing
Friction during valve opening and closing, reduces and opens and closes moment, reduce the prooving of valve seat simultaneously, ball seat life-span and sealing property are greatly improved.
Beneficial effect: the disc spring that the present invention provides loads automatic compensating ball valve and compared to the prior art has the advantage that
The disc spring that the present invention provides loads automatic compensating ball valve, reasonable in design, and sealing is high, when can reduce ball valve keying
Frictional force, reduce the abrasion of valve seat, improve valve service life, secondly when abrasion occurs in valve seat, by the elastic force of disc spring
Load and abrasion is compensated, the failure risk that abrasion brings can be lowered, the service life of valve is substantially improved.
