The utility model relates to a stop valve is opened soon in pneumatic tee bend of high temperature, including the tee bend disk seat, be equipped with the case in the tee bend disk seat, the pot head has a valve clack on the case, this valve clack with the upper end point contact of tee bend disk seat, the valve clack inboard with be equipped with balancing unit between the tee bend disk seat outside, the cover has a flexible graphite sealing washer on the case, and this flexible graphite sealing washer lower extreme is equipped with the axle sleeve, and this axle sleeve overcoat has a spring, this spring with flexible graphite sealing washer lower extreme offsets, through setting up valve clack and the point contact of tee bend disk seat upper end and balancing unit's interact, makes the stop valve have the effect that the fine setting keeps the level, can be high temperature resistant through setting up the flexible graphite sealing washer, fix the flexible graphite sealing washer through setting up axle sleeve and spring, the utility model relates to a rationally, can promote on a large scale.
Description
Technical field
The utility model is related to stop valve technical field, more particularly to a kind of high temperature Pneumatic three-way to 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 to press to flap
Power, is not leaked with forced seal face.When medium enters valve by flap lower section, the resistance overcome required for operating physical force is valve
The frictional force of bar and filler and the thrust as produced by the pressure of medium, the power of closing valve are bigger than the power of valve opening door, so valve rod
Diameter it is big, the failure of valve rod bending can otherwise occur.
Utility model content
To the above-mentioned state of the art, technical problem to be solved in the utility model be provide a kind of point contact,
Remain that horizontal high temperature Pneumatic three-way opens stop valve soon.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of high temperature Pneumatic three-way opens cut-off soon
Valve, including threeway valve seat, are provided with valve element in the threeway valve seat, the valve element upper end is cased with flap, the flap and the threeway
Valve seat upper extreme point is contacted, and bascule is provided between the flap inner side and threeway valve seat outside, and the valve core upper sleeve has
Flexible graphite sealing ring, the flexible graphite sealing ring lower end is provided with axle sleeve, and spring is cased with outside the axle sleeve, the spring and the flexibility
Carbon seal 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, the utility model has the advantage of：The utility model is by setting flap and threeway valve seat
The point contact and the interaction of bascule of upper end, make stop valve have the effect of fine setting holding level；It is flexible by setting
Carbon seal ring can high temperature resistant, by setting axle sleeve and spring come fixing flexible carbon seal ring, the utility model is reasonable in design,
Can large-scale promotion.
Brief description of the drawings
Fig. 1 opens stop valve structure schematic diagram soon for a kind of high temperature Pneumatic three-way of the utility model；
Fig. 2 opens stop valve operating diagram one soon for a kind of high temperature Pneumatic three-way of the utility model；
Fig. 3 opens stop valve operating diagram two soon for a kind of high temperature Pneumatic three-way of the utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.
As Figure 1-3, a kind of high temperature Pneumatic three-way opens stop valve, including threeway valve seat 1 soon, in the threeway valve seat 1
Valve element 2 is provided with, the upper end of the valve element 2 is cased with flap 3, the flap 3 is contacted with the upper extreme point of threeway valve seat 1, in the flap 3
Bascule 4 is provided between side and the outside of the threeway valve seat 1, flexible graphite sealing ring 5 is cased with the valve element 2, the flexibility
The lower end of carbon seal ring 5 is provided with axle sleeve 6, is cased with spring 7 outside the axle sleeve 6, the spring 7 and the lower end of the flexible graphite sealing ring 5
Offset, the lower end of the valve element 2 is provided with base 8, the side of the base 8 is cased with dust cover 9, and the side of the base 8 is cased with graphite work
Plug ring 10, the bascule 4 is steel ball.
Operation principle is briefly explained：
The lower surface contact of the upper port of threeway valve seat 1 is that point is contacted with flap 3, and upper terminal contacts are not contacted, the sky for having 0.5mm
Gap.Triple valve, 1 inside is equipped with bascule 4, there is 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 and the contact point of flap 3 wear and tear, because there is the compensation space of 0.5mm, connect
Contact will be shifted up, and because there is compensation space between the small ball of bascule 4 and flap 3, the perpendicular bisector of valve element 2 and threeway valve seat 1
Center of circle line overlap all the time, this ensures that the level all the time of flap 3.
Part works in hot environment, sealing ring, and piston ring all uses graphite material, and soft graphite is elastic due to not having, 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 in base 8 because piston ring
Set and dust cover are cased with step, put after piston bush, with annular gasket pad, are putting dust cover 9, are putting cover-use screw
It is fixed.
First stomata 11 is ventilated, and flap 3 is moved down, and blocks P1, leads to P2, P3.Second stomata 12 is ventilated, and flap 3 is upward
It is mobile, block P3, P1, P2 ventilation.End spaces is exactly an effect for cylinder under part.
Compared with prior art, the utility model has the advantage of：The utility model is by setting flap and threeway valve seat
The point contact and the interaction of bascule of upper end, make stop valve have the effect of fine setting holding level；It is flexible by setting
Carbon seal ring can high temperature resistant, by setting axle sleeve and spring come fixing flexible carbon seal ring, the utility model is reasonable in design,
Can large-scale promotion.
