Description

A kind of disc spring loads the double ball valves automatically compensated
Technical field
This utility model relates to a kind of valve, is specifically related to a kind of reasonable in design, good seal performance, and service life is long, and the disc spring of function admirable loads the double ball valves automatically compensated.
Background technology
Ball valve is big because of its latus rectum, without flow resistance, pressure valve is big, thus is widely used in the market, but general ball valve is all single ball-valve structure, in use all can there is prooving of valve seat problem in valve switch every time, internal hemorrhage due to trauma once occurs, just needs to close whole up-stream system and could realize cutting off and safeguarding, especially in new energy resources system, ball valve leaks as unique stop valve of whole piece pipeline, one end, the most easily causes a serious accident.
Therefore, necessary on the basis of prior art, a kind of reasonable in design of design research and development, sealing is high, and safety is good, and service life is long, and the disc spring having wide range of applications loads the double ball valves automatically compensated.
Summary of the invention
Goal of the invention: the purpose of this utility model is that sealing is high, and safety is good, and service life is long, and the disc spring having wide range of applications loads the double ball valves automatically compensated for the deficiencies in the prior art, R & D design one reasonable in design.
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 the double ball valves automatically compensated, and it includes: valve body, two the mutually isostructural ball valve assemblies being arranged in valve body;Described ball valve assembly includes supporting seat, it is arranged on the valve seat supported in seat, the valve ball being arranged on valve seat, supporting seat two side and lay disc spring, the upper end of valve ball connects valve rod, is provided with filler between valve body and valve rod, packing press ring is installed on filler, 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 the alignment pin controlling switch over travel;The two ends of valve body are all screwed with end connector;
Two mutually isostructural ball valve assemblies, on the same level line of valve inner, are interconnected.
Preferably, above-described disc spring loads the double ball valves automatically compensated, and is provided with O RunddichtringO between described end connector and valve body.
Preferably, above-described disc spring loads the double ball valves automatically compensated, and is provided with O RunddichtringO between described valve body and support seat.
Disc spring described in the utility model loads the double ball valves automatically compensated, and 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 this utility model provides loads the double ball valves automatically compensated and compared to the prior art has the advantage that
The disc spring that this utility model provides loads the double ball valves automatically compensated, reasonable in design, sealing is high, frictional force when ball valve opens and closes can be reduced, reduce the abrasion of valve seat, improve valve service life, secondly when abrasion occurs in valve seat, loaded by the elastic force of disc spring and abrasion is compensated, the failure risk that abrasion brings can be lowered, the service life of valve is substantially improved.
And use double ball valve assembly structure, it is provided with valve ball switch at two, in actual use, using ball valve to switch, at usual one, ball valve is normally opened or the normally off according to demand, at one during ball valve leakage, can use as quick action emergency valve by using ball valve at another, ensure that and system can be run well, be not required to cut off whole system, thus property loss can be reduced and avoid security incident.
Accompanying drawing explanation
Fig. 1 is the structural representation that the disc spring that this utility model provides loads the double ball valves automatically compensated.
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 all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
As it is shown in figure 1, a kind of disc spring loads the double ball valves automatically compensated, it includes: valve body 8, two the mutually isostructural ball valve assemblies being arranged in valve body 8;Described ball valve assembly includes supporting seat 4, it is arranged on the valve seat 6 supported in seat 4, the valve ball 7 being arranged on valve seat 6, supporting seat 4 two side and lay disc spring 3, the upper end of valve ball 7 connects valve rod 10, is provided with filler 9 between valve body 8 and valve rod 10, packing press ring 11 is installed on filler 9, valve rod 10 upper end is connected with hex nut 13 and handle 15 successively, is provided with spring washer 12 between hex nut 13 and handle 15, and valve body 8 top is provided with the alignment pin 14 controlling switch over travel;The two ends of valve body 8 are all screwed with end connector 1;
Two mutually isostructural ball valve assemblies, on the same level line within valve body 8, are interconnected.
Above-described disc spring loads the double ball valves automatically compensated, and is provided with O RunddichtringO 2 between described end connector 1 and valve body 8.
Above-described disc spring loads the double ball valves automatically compensated, and is provided with O RunddichtringO 2 between described valve body 8 and support seat 4.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
