Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of full steam tracing butterfly valve.
Background technology
At present, when people adopt butterfly valve to carry some high viscosity mediums, for preventing medium cooled and solidified, it usually needs butterfly valve is carried out isothermal holding, but existing isothermal holding is generally only and arranges insulation jacket at valve outer surface, and such heat insulation effect is often not ideal enough.
Summary of the invention
For the deficiencies in the prior art, the invention provides the full steam tracing butterfly valve of a kind of better heat preservation.
nullFor achieving the above object，The invention provides a kind of full steam tracing butterfly valve，Include valve rod、Butterfly plate、Valve body、And be surrounded on outside this valve body and be fixed on the insulation jacket on this valve body，Insulation stream chamber is formed between described insulation jacket and valve outer surface，Described insulation jacket is additionally provided with the jacket steam import and jacket steam outlet that communicate with described insulation stream chamber，Described valve rod is located on valve body，Butterfly plate is arranged in body cavity，And be fixed on valve rod，Described valve rod be axially respectively arranged at two ends with steam inlet channel and steam output channel，Described butterfly plate is provided with a circle steam stream chamber，Described butterfly plate is additionally provided with the butterfly plate steam inlet and butterfly plate steam (vapor) outlet that communicate with described steam stream chamber，Between steam inlet channel on described butterfly plate steam inlet and valve rod、And be connected each through connecting tube between described butterfly plate steam (vapor) outlet and the steam output channel on valve rod.
The invention has the beneficial effects as follows: adopt said structure, owing to the present invention except arranging insulation jacket except valve body, one circle steam stream chamber is also set on butterfly plate, and make described steam stream chamber be connected with the steam inlet channel on valve rod and steam output channel by connecting tube, hence in so that steam not only can circulation in the insulation stream chamber outside valve body, and circulation in the steam stream chamber on butterfly plate is entered into also by valve rod, thus significantly improving the heat insulation effect of butterfly valve.
The present invention can be further arranged between described butterfly plate and valve body and be additionally provided with elastic seal ring, on butterfly plate, correspondence offers the annular gap slot for housing elastic seal ring, leaf spring and taper trim ring has been clamped between axial inner ends face and the annular gap slot bottom surface of elastic seal ring, and described taper trim ring is corresponding between leaf spring and elastic seal ring, the bigger diameter end of taper trim ring is resisted against on leaf spring, the miner diameter end of taper trim ring embeds in the axial inner ends face of elastic seal ring, the axial outer end face of elastic seal ring is pressed with pressing plate, and described pressing plate is locked by screw and butterfly plate.
Adopt said structure, by the setting of leaf spring and taper trim ring, not only can spacing fixing elastic seal ring better, and elastic seal ring can also be made to be in swelling state all the time, thus the sealing property being greatly promoted between butterfly plate and valve body.
The present invention may further be provided enter into described steam, the central axis of output channel preferably with the central axis of valve rod on the same line.So arrange, valve rod can be prevented effectively from and when driving butterfly plate to rotate, the steam of circulation is caused eccentric force.
It is elastic connecting pipe that the present invention may further be provided as described connecting tube.
