Abstract
The utility model relates to an all-welded elastic metal seal butterfly valve which comprises a valve body, a valve plate and an elastic metal seal ring mounted on the sealed part of the valve body and the valve plate. The utility model realizes the elastic seal of metal by utilizing pure metal, and avoids the non-metallic part of the composite metal seal butterfly valve from losing during brushing and squeezing; by adopting the elastic U-shaped metal seal ring, the valve can effectively overcome the damage of impurities on sealing due to the elasticity and realize the ideal equative sealing and the long service life and maintenance free effects; the all-welded structure valve body also meets special requirements of valve for great heating power in direct-buried pipe network and is applicable to various industrial fields; the lowest operating temperature is -253 DEG C and the highest operating temperature is 650 DEG C; the all-welded elastic metal seal butterfly valve not only can cut off the medium, but also can regulate the flow of the medium optionally due to good flow characteristic.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of full welding elastic metallic seal butterfly valve.
Background technique
Butterfly valve is Flap valve again, it is a kind of modulating valve simple in structure, also can be used for simultaneously the switch control of low pressure pipeline medium, existing bidirectional metallic seal butterfly valve, mostly be that elasticity by rubber realizes sealing, though its two way sealed performance is good, heat-resisting quantity is restricted, simultaneously, when the rubber seal butterfly valve uses as throttling,, rubber base is peeled off because the improper use meeting produces cavitation erosion, situations such as damage take place, be easy to generate distortion, simultaneously, nonmetal hermetic unit also is easy to incur loss in washing away and pushing, and causes leaking, working life is short, and overall performance is not high.
The model utility content
For addressing the above problem, the utility model provides a kind of more erosion resistance, operational torque is little, sealability is reliable, the switching position is welded the elastic metallic seal butterfly valve accurately entirely, has avoided traditional metal hard-sealing butterfly valve to be squeezed in cold and hot distortion and has caused the deficiency of leakage.
Full welding elastic metallic seal butterfly valve of the present utility model comprises valve body and valve plate, at the sealing position of valve body and valve plate the elastic metallic seal ring is installed.
Full welding elastic metallic seal butterfly valve of the present utility model, described elastic metallic seal ring is a stainless pipe, stainless pipe is fixed on the edge of valve plate.
Full welding elastic metallic seal butterfly valve of the present utility model, described elastic metallic seal ring comprises stainless pipe, is fixed with elastic alloy U type ring on the surface in the stainless pipe outside.
Full welding elastic metallic seal butterfly valve of the present utility model, described elastic metallic seal ring comprises stainless pipe, is fixed with elastic alloy U type ring on the surface of stainless pipe inboard.
Full welding elastic metallic seal butterfly valve of the present utility model, described stainless pipe can also be bourdon tube.
The beneficial effect that the utility model welds the elastic metallic seal butterfly valve entirely is: the utility model has realized that pure metal seals metallic spring, the possibility of having avoided the nonmetal hermetic unit of composite metal seal butterfly valve in washing away and pushing, to lose, the design of elasticity U type metal o-ring, make valve pass through self elasticity, effectively overcome the damage of impurity to sealing, and realized that desirable peer seals and the non-maintaining long lifetime uses, the design of all-welded structure valve body, also satisfied in the direct-burried pipe network huge thermal stress to the specific (special) requirements of valve, seal arrangement of the present utility model, be not only applicable to common hard seal butterfly valve, also be applicable to the hard seal butterfly valve that has extension bar, can be applicable to various industrial fields, minimum serviceability temperature reaches-253 ℃, and maximum operation (service) temperature reaches 650 ℃, because its good Flow characteristics, promptly can close and block medium, also can regulate the flow of medium arbitrarily.

Embodiment
Below in conjunction with Figure of description the utility model being welded the elastic metallic seal butterfly valve entirely is described further.
Referring to Fig. 1-Fig. 4, full welding elastic metallic seal butterfly valve of the utility model embodiment 1, comprise valve body 1, be installed in valve plate 3 in valve body 1 runner by valve shaft 2, sealing position at valve body 1 and valve plate 3 is equipped with elastic metallic seal ring 4, elastic metallic seal ring 4 is a stainless pipe, and stainless pipe is fixed on the edge of valve plate 3
The sealing part of described valve plate 3 and valve body 1 is provided with elastic metallic seal ring 4, and elastic metallic seal ring 4 is for being located at stainless pipe 5 on the butterfly plate outer.
Referring to Fig. 5, different with model utility embodiment 1 is, full welding elastic metallic seal butterfly valve of the utility model embodiment 2, and elastic metallic seal ring 4 comprises stainless pipe 5, is fixed with elastic alloy U type ring 6 on the surface in the stainless pipe outside.
Referring to Fig. 6, different with model utility embodiment 1 is, full welding elastic metallic seal butterfly valve of the utility model embodiment 3, and elastic metallic seal ring 4 comprises stainless pipe 5, is fixed with elastic alloy U type ring 6 on the surface of stainless pipe inboard.
Referring to Fig. 7, different with model utility embodiment 1 is, full welding elastic metallic seal butterfly valve of the utility model embodiment 4, and stainless pipe 5 can also be bourdon tube 7.
Elastic metallic seal ring 4 of the present utility model is not only applicable to common hard seal butterfly valve, is applicable to the hard seal butterfly valve that has extension bar yet.The utility model has realized that pure metal seals metallic spring, the possibility of having avoided the nonmetal hermetic unit of composite metal seal butterfly valve in washing away and pushing, to lose, the design of elasticity U type metal o-ring, make valve pass through self elasticity, effectively overcome the damage of impurity to sealing, and realized that desirable peer seals and the non-maintaining long lifetime uses, the design of all-welded structure valve body, also satisfied in the direct-burried pipe network huge heating power to the specific (special) requirements of valve, can be applicable to various industrial fields, minimum serviceability temperature reaches-253 ℃, maximum operation (service) temperature reaches 650 ℃, because its good Flow characteristics promptly can be closed and be blocked medium, also can regulate the flow of medium arbitrarily.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in related domain make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
