In sum, work out and a kind ofly both possessed good thermal insulation property to have the stopcock that can effectively guarantee valve seal be one of current stopcock making field major issue that need to solve.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of sealing thermal insulation stopcock that can guarantee the integrity of sealing and can effectively realize heat insulation effect.
The technical scheme in the invention for solving the technical problem is: a kind of thermal-insulating sealing jacket plug valve, valve body, flap, valve rod, described flap is located in valve body, valve rod is connected with flap, comprise valve seat, described valve seat is embedded in valve body, flap is fixedly connected with valve body by valve seat, flap and valve rod are integral type structure, described valve rod extends to outside valve body, described valve body top is provided with valve gap, valve cover chamber is every valve body and extend the valve stem part outside valve body, described valve gap is connected by seal ring with valve body, described valve outer wall is provided with chuck, described chuck inwall and valve outer wall form ellipticity Seal cage.
Described chuck is provided with circulation connection mouth, and described circulation connection mouth is located at respectively the chuck left and right sides, guarantees thermal insulation medium circulating between chuck cavity and pipeline, thereby guarantees the control to medium temperature in valve body.
Described chuck bottom is provided with blowdown connection mouth, the utility model is by setting up blowdown connection mouth in chuck bottom, to guarantee that the thermal insulation medium that chuck inwall and valve outer wall form in ellipticity Seal cage can repel magazine in time, guarantee the turbidity test of thermal insulation medium, thereby further improve the heat insulation effect of sealing thermal insulation stopcock;
Further, in order better to guarantee the heat insulation effect of stopcock, the utility model is provided with temperature transducer in chuck inside, sensor and alarm buzzer adopt communication connection, its temperature setting is set to 150-200 ℃, when temperature is too low, can impel in time alarm buzzer alarm, remind staff to process in time, beneficial effect is obvious.
Dismounting after connecting for the ease of circulation, the applicability of raising sealing thermal insulation stopcock, described circulation connection mouth is pipe thread or flange arrangement.
In order to guarantee the sealing of stopcock, described sealing configuration is made by stopcock seal gease.
In order to improve the practicability of valve body, increase the service life, described chuck and valve body are integral type structure.
The beneficial effects of the utility model are:
1. good airproof performance: the utility model has adopted the valve mechanism with chuck, also sets up seal ring between valve body and valve rod, can guarantee the integrity of its sealing while making valve working, strengthens sealing effect;
2. high insulating effect: the utility model, by setting up chuck in valve body outside, makes chuck inwall and valve outer wall form oblong cavity, passes into thermal insulation medium in cavity, effectively the circulation medium in valve body is incubated; Because described chuck bottom is provided with blowdown connection mouth, the rubbish that thermal insulation medium in cavity can be produced is cleared up in real time, effectively protects the stability of its runner interior media temperature, thereby further improves the heat insulation effect of sealing thermal insulation stopcock again;
3. the utility model is simple in structure, and beneficial effect is obvious, is suitable for industrialization and produces.
