Abstract
A compound seal valve comprises a valve body and a valve cover. The valve body and the valve cover are oppositely and fixedly connected. A packing ring and an annular spirotallic gasket are arranged between the valve body and the valve cover, wherein the packing ring and the annular spirotallic gasket play sealing functions. The packing ring and the spirotallic gasket are two rings, wherein one of the two rings is big, the other one of the two rings is small, and the two rings do not cross. The packing ring forms a level of seal, and the spirotallic gasket also forms another level of seal. Accordingly, a compound seal structure is formed between the valve body and the valve cover, seal effect is good, leakage does not happen, the performance of the compound seal valve is stable, and service life is long.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of compound seal valve.
Background technique
Be in fluid system, be used for controlling direction, the pressure of fluid, the device of flow.Valve is the device that pipe arrangement and the interior medium (liquid, gas, powder) of equipment is flowed or stop and controlling its flow.
Valve is a controlling component in the pipeline fluid delivery system, and it is to be used for changing path section and media flow direction, has water conservancy diversion, by functions such as, throttling, non-return, shunting or overflow releases.The valve that is used for fluid control, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are various, the inside nominal diameter of valve is used valve to the industrial pipeline that latus rectum reaches 10m greatly from atomic little Gauge Valves.Valve can be used for controlling all kinds fluid flows such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid; But the working pressure 0.0013MPa of valve is to the ultrahigh pressure of 1000MPa, and operating temperature is from the high temperature of-269 ℃ ultralow temperature to 1430 ℃.The control of valve can be adopted the multiple kind of drive, as manual, electronic, surge, pneumatic, turbine, electromagnetism is moving, electromagnetism surges, electricity surges, gas-liquid is moved, spur wheel, umbrella gear driving etc.; Can be under the effect of pressure, temperature or other form transducing signal; By predetermined requirement action; Perhaps do not rely on transducing signal and simply open or close; Valve rely on to drive or automechanism makes open-shut device do up-down, slippage, swing or rotation motion, thereby the size that changes its Flow area is to realize its control function.
Existing a lot of valve comprises valve body and valve gap, and said valve body and valve gap connect through the bolt relative fixed; Seal through pad between said valve body and the valve gap, its sealability is unreliable, leaks easily; Cause the valve usability not good, life of valve is not long.
The model utility content
The problem that the utility model will solve is to improve the problem of compound seal valve in the background technique.
In order to overcome the above problems; The utility model provides a kind of compound seal valve; Comprise valve body and valve gap; Said valve body and valve gap connect through the bolt relative fixed, are provided with the packing ring that seals and the spirotallic gasket of annular between said valve body and the valve gap, and said packing ring and spirotallic gasket are small one and large one and Uncrossed two annulars mutually.
Be respectively equipped with the terraced structure of corresponding annular on the end face of the mutual correspondence of said valve body and valve gap, wherein be provided with packing ring between the ledge structure, be provided with spirotallic gasket between another ledge structure.
Be provided with the bellows support ring between said valve body and the valve gap; Be respectively equipped with the terraced structure of corresponding annular on the end face of the mutual correspondence of said valve body and bellows support ring; Wherein be provided with packing ring between the ledge structure, be provided with spirotallic gasket between another ledge structure.
Be provided with elastic element between said packing ring and the valve body.
Said elastic element is the butterfly leaf spring.
Be provided with dunnage between said elastic element and the packing ring.
The described compound seal valve of the utility model; Comprise valve body and valve gap; Said valve body and valve gap connect through the bolt relative fixed; Be provided with the spirotallic gasket of the packing ring that seals and annular between said valve body and the valve gap, said packing ring and spirotallic gasket are small one and large one and Uncrossed two annulars mutually.Packing ring forms primary seal, and spirotallic gasket forms primary seal again, makes to form compound sealing structure between valve body and the valve gap, and good sealing effect can not leak, the stable performance of valve, and the life-span is longer.

Embodiment
Below in conjunction with accompanying drawing a kind of compound seal valve of the utility model is described further.
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4; The compound seal valve of present embodiment; Comprise valve body 1 and valve gap 2; Valve body 1 and valve gap 2 connects through the bolt relative fixed, is provided with the packing ring 5 that seals and the spirotallic gasket 4 of annular between valve body 1 and the valve gap 2, and packing ring 5 and spirotallic gasket 4 are small one and large one and Uncrossed two annulars mutually.
In the present embodiment, be respectively equipped with the terraced structure of corresponding annular on the end face of said valve body 1 and valve gap 2 mutual correspondences, wherein be provided with packing ring 5 between the ledge structure, be provided with spirotallic gasket 4 between another ledge structure.Packing ring forms primary seal, and spirotallic gasket forms primary seal again, makes to form compound sealing structure between valve body and the valve gap, and good sealing effect can not leak, the stable performance of valve, and the life-span is longer.Certainly; Said valve body 1 and valve gap 2 also are not necessarily all directly to contact with packing ring 5 and spirotallic gasket 4; Be provided with bellows support ring 3 such as being transformed between said valve body 1 and the valve gap 2; Be respectively equipped with the terraced structure of corresponding annular on the end face of valve body 1 and bellows support ring 3 mutual correspondences, wherein be provided with packing ring 5 between the ledge structure, be provided with spirotallic gasket 4 between another ledge structure.
In the present embodiment, be provided with elastic element between said packing ring 5 and the valve body 1.Make the sealing effect between packing ring 5 and the valve body 1 further improve.In the present embodiment, said elastic element is a butterfly leaf spring 6, because the space is extremely limited, adopts more conserve space of butterfly leaf spring, and cost is also lower.In the present embodiment, be provided with dunnage 7 between said elastic element and the packing ring 5.This design can be avoided elastic element to directly act on causing packing ring 5 to deform on the packing ring 5, influence sealing effect.
The utility model is not limited to above embodiment and conversion.
