Description
Technical field
The present invention relates to stop valve technical field, more particularly to a kind of high temperature Pneumatic three-way open stop valve soon.
Background technology
Stop valve belongs to forced seal formula valve also known as pipe valve valve, so in valve closing, it is necessary to apply pressure to flap
Power, is not leaked with forced seal face.When valve is entered below medium is by flap, the resistance for overcoming required for operating physical force, is valve
The frictional force of bar and filler and the thrust produced by the pressure of medium, the power of closing valve is bigger than the power of valve opening door, so valve rod
Diameter big, the fault of valve rod bending can otherwise occur.
Content of the invention
To the above-mentioned state of the art, the technical problem to be solved is to provide a kind of point contact, all the time
The high temperature Pneumatic three-way of holding level opens stop valve soon.
The present invention solves the technical scheme that adopted of above-mentioned technical problem：A kind of high temperature Pneumatic three-way opens stop valve soon,
Including threeway valve seat, in the threeway valve seat, valve element is provided with, the valve element upper end is cased with flap, the flap and the threeway valve seat
Upper extreme point is contacted, on the inside of the flap and on the outside of the threeway valve seat between be provided with bascule, the valve core upper sleeve has flexibility
Carbon seal ring, the flexible graphite sealing ring lower end is provided with axle sleeve, is cased with spring outside the axle sleeve, the spring and the soft graphite
Sealing ring lower end offsets.
Further, the valve element lower end is provided with base.
Further, the chassis side is cased with dust cover.
Further, the chassis side is cased with carbon piston ring.
Further, the bascule is steel ball.
Compared with prior art, it is an advantage of the current invention that：The present invention is by setting flap and the point of threeway valve seat upper end
Contact and the interaction of bascule, make stop valve have the effect of fine setting holding level；By arranging flexible graphite sealing
Circle can be high temperature resistant, and by setting axle sleeve and spring come fixing flexible carbon seal ring, the present invention is reasonable in design, can push away on a large scale
Extensively.
Description of the drawings
Fig. 1 drives stop valve structure schematic diagram soon for a kind of high temperature Pneumatic three-way of the present invention；
Fig. 2 opens stop valve operating diagram one soon for a kind of high temperature Pneumatic three-way of the present invention；
Fig. 3 opens stop valve operating diagram two soon for a kind of high temperature Pneumatic three-way of the present invention.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing, the present invention is entered
Row is further described.
As Figure 1-3, a kind of high temperature Pneumatic three-way opens stop valve soon, including threeway valve seat 1, in the threeway valve seat 1
Valve element 2 is provided with, 2 upper end of the valve element is cased with flap 3, the flap 3 is contacted with 1 upper extreme point of threeway valve seat, in the flap 3
Bascule 4 being provided between side and 1 outside of the threeway valve seat, flexible graphite sealing ring 5 is cased with the valve element 2, the flexibility
5 lower end of carbon seal ring is provided with axle sleeve 6, is cased with spring 7 outside the axle sleeve 6, the spring 7 and 5 lower end of the flexible graphite sealing ring
Offset, 2 lower end of the valve element is provided with base 8,8 side of the base is cased with dust cover 9,8 side of the base is cased with graphite work
Plug ring 10, the bascule 4 is steel ball.
Operation principle brief description：
The lower surface contact of 1 upper port of threeway valve seat and flap 3 are to contact, and upper terminal contacts are not contacted, the sky for having 0.5mm
Gap.Three-way valve, 1 inside is equipped with bascule 4, has compensation space between small ball and flap 3, and flap 3 can be made to make to justify around valve element 2
Zhou Yundong (displacement very little).After threeway valve seat 1 is with the abrasion of 3 contact point of flap, because there is the compensation space of 0.5mm, connect
Contact will be shifted up, and because have compensation space, 2 perpendicular bisector of valve element and threeway valve seat 1 between 4 small ball of bascule and flap 3
Center of circle line overlap all the time, this ensures that the level all the time of flap 3.
Part hot environment work, sealing ring, piston ring all uses graphite material, soft graphite due to there is no elasticity, no
It is fixed easily.The fixed form axle sleeve of sealing ring is fixed, and is stepped up with the elastic force of spring 7.Piston ring set is in base 8, because piston ring
Set and dust cover are cased with step, after putting piston bush, with annular gasket pad, are putting dust cover 9, are putting cover-use screw
Fixing.
First pore 11 is ventilated, and flap 3 is moved down, and blocks P1, logical P2, P3.Second pore 12 is ventilated, and flap 3 is upwards
Mobile, P3 is blocked, P1, P2 ventilate.Under part, end spaces is exactly the effect of a cylinder.
Compared with prior art, it is an advantage of the current invention that：The present invention is by setting flap and the point of threeway valve seat upper end
Contact and the interaction of bascule, make stop valve have the effect of fine setting holding level；By arranging flexible graphite sealing
Circle can be high temperature resistant, and by setting axle sleeve and spring come fixing flexible carbon seal ring, the present invention is reasonable in design, can push away on a large scale
Extensively.
