Description
Technical field
This utility model relates to a kind of valve, is specifically related to a kind of reasonable in design, and good seal performance, service life is long, property
Disc spring that can be excellent 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: the purpose of this utility model is for the deficiencies in the prior art, R & D design one reasonable in design is close
Feng Xinggao, safety 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 this utility model is taked 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 described in the utility model loads automatic compensating ball valve, by using the ball valve of spring washer loading valve seat, permissible
Reduce friction during valve opening and closing, reduce and open and close moment, reduce the prooving of valve seat simultaneously, ball seat life-span and sealing are greatly improved
Performance.
Beneficial effect: the disc spring that this utility model provides loads automatic compensating ball valve and compared to the prior art has the advantage that
The disc spring that this utility model provides loads automatic compensating ball valve, reasonable in design, and sealing is high, can reduce ball valve and open
Frictional force when closing, reduces the abrasion of valve seat, improves valve service life, secondly when abrasion occurs in valve seat, by disc spring
Elastic force loads and compensates abrasion, can lower the failure risk that abrasion brings, the service life of valve is substantially improved.
Accompanying drawing explanation
Fig. 1 is the structural representation that the disc spring that this utility model provides loads automatic compensating ball valve.
Fig. 2 is to support seat, mounting structure schematic diagram between valve seat and disc spring in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this
Utility model rather than limit scope of the present utility model, after having read this utility model, those skilled in the art are to this
The amendment of the various equivalent form of values of utility model all falls within the application claims limited range.
As depicted in figs. 1 and 2, a kind of disc spring loads automatic compensating ball valve, it is characterised in that it includes: valve body (8), peace
The support seat (4) being contained in valve body (8), is arranged on the valve seat (6) supported in seat (4), is arranged on the valve on valve seat (6)
Ball (7), supports seat (4) back and lays disc spring (3), and the two ends of valve body (8) are all screwed with end connector (1), disc spring (3)
It is positioned in the middle of support seat (4) and end connector (1)；
The upper end of valve ball (7) connects valve rod (10), is provided with filler (9), fills out between valve body (8) and valve rod (10)
Being provided with packing press ring (11) on material (9), valve rod (10) upper end is connected with hex nut (13) and handle (15), and six
Being provided with spring washer (12) between angle nut (13) and handle (15), valve body (8) top is provided with control switch over travel
Alignment pin (14).
Above-described disc spring loads automatic compensating ball valve, is provided with O type close between described end connector (1) and valve body (8)
Seal (2).
Above-described disc spring loads automatic compensating ball valve, is provided with O type between described end connector (1) and support seat (4)
Sealing ring (2).
The disc spring that this utility model provides loads automatic compensating ball valve, can reduce frictional force when ball valve (7) opens and closes, reduce valve
The abrasion of seat (6), improves valve service life, secondly when wearing and tearing occurs in valve seat (6), is added by the elastic force of disc spring (3)
Carry and abrasion is compensated, the failure risk that abrasion brings can be lowered, the service life of valve is substantially improved.
The above is only preferred implementation of the present utility model, it is noted that for those skilled in the art
For, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications are also
