Abstract
It the utility model is related to a kind of self sealss plug valve.Mainly solve the problems, such as that poorly sealed close, seepage easily occurs for existing plug valve.It is characterized in that：The valve body（3）Inside is equipped with seal cartridge（8）, seal cartridge（8）It is interior to be provided with valve element（6）, the seal cartridge（8）Inner surface and valve element（6）By cone match, the valve element（6）Top is provided with bonnet（7）.The self sealss plug valve can realize self sealss when closed, avoid seepage, increase the service life.
Description
Technical field
A kind of valve is the utility model is related to, specifically a kind of self sealss plug valve.
Background technology
Current plug valve valve element runner turn to valve flowing channel one to when, plug valve open, valve element runner rotate
To with valve flowing channel it is perpendicular when, plug valve close.Now realized and sealed by import end pressure, easily occurred poorly sealed
Close, seepage phenomenon, reduction of service life.
The content of the invention
In order to overcome the shortcomings of that poorly sealed close, seepage easily occurs for existing plug valve, the utility model provides one kind certainly
Plug valve is sealed, the self sealss plug valve can realize self sealss, avoid seepage, increase the service life when closed.
The technical solution of the utility model is：A kind of self sealss plug valve, including valve body, the valve inner are equipped with sealing
Bushing, seal cartridge is interior to be provided with valve element, and the seal cartridge inner surface is provided with valve element by cone match, the valve element top
Bonnet.
Fixed between the seal cartridge and valve body by straight pin.
Cock is connected with the top of the valve element, cock top is connected with handwheel.
The utility model has the advantages that：Due to taking such scheme, seal cartridge is provided with valve body, and seal
By cone match between bushing and the valve element of inside, so when switching spool, pass through the conical surface between valve element and seal cartridge
Self sealss are formed, sealing effectiveness is enhanced, solves leakage problems, so as to extend the service life of plug valve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
The tight cap of 1- unions in figure, 2- cutting ferrules, 3- valve bodies, 4- handwheels, 5- cocks, 6- valve elements, 7- bonnets, 8- seal cartridges,
9- straight pins.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Shown by Fig. 1, a kind of self sealss plug valve, including valve body 3, the inner transverse of valve body 3 is provided with runner, in valve body 3
The perpendicular longitudinal holes of transverse flow channels are longitudinally provided with the heart, longitudinal holes are built-in with valve element 6, the transverse flow channels of the both sides of valve element 6
Seal cartridge 8 is built-in with, the inner surface of seal cartridge 8 is overall in up big and down small by cone match, i.e. valve element 6 with valve element 6
Cone, the runner of horizontal direction is provided with cone, seal cartridge 8 is engaged with the outer surface of valve element 6.The seal cartridge 8 with
Fixed between valve body 3 by straight pin 9, the top of valve element 6 is provided with bonnet 7, and bonnet 7 is connected with valve body 3.The valve element 6 pushes up
Portion is connected with cock 5, and the top of cock 5 is connected with handwheel 4, can be rotated by rotating handwheel 4 with movable valve plug 6.Described one end of valve body 3
The tight cap 1 of union is connected with by cutting ferrule 2, so as to be connected with pipeline.
It when valve element 6 switchs, while can move up and down, and can pass through between valve element 6 and seal cartridge 8 within the specific limits
The conical surface forms self sealss, increases sealing effectiveness, solves leakage problems, so as to increase the service life.
