Abstract
The utility model provides a triple sealing corrugated pipe stop valve, comprising an upper valve body, a lower valve body, a valve clack disposed in the internal of the lower valve body, a valve rod penetrating the upper valve body and fixedly connected with the valve clack, and a corrugated pipe disposed in the upper valve body and sleeved on the valve rod, the triple sealing corrugated pipe stop valve is characterized in that, the contact part of the valve rod and the upper end of the upper valve body is provided with an upper stuffing box, the upper end of the corrugated pipe is welded on the upper stuffing box; the lower end of the corrugated pipe and the valve rod are welded together; and the contact part of the valve rod and the lower end of the upper valve body is also provided with a lower stuffing box. The triple sealing corrugated pipe stop valve in the utility model can bear work condition of dust and impurities in a medium, improve use work condition of the corrugated pipe, effectively prolong service lifetime of the corrugated pipe, and reach purpose of prolonging service lifetime of the valve.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of triple seal bellows stop valve.
Background technique
Existing bellows stop valve, in use, especially for impurity in the medium and the more operating mode of dust; Existing bellows stop valve; Because bellows is exposed in the medium fully, impurity and dust are easy to get into the fold the inside of bellows, and attached to bellows surface; Finally cause bellows to follow the string and lost efficacy, whole deck valve door also just can not use.
The model utility content
In view of above-mentioned deficiency, the object of the present invention is to provide a kind of bellows stop valve with triple seal, it can effectively improve the working life of bellows in the operating mode that contains dust and impurity medium, prolong the working life of valve.
In order to achieve the above object; The utility model has adopted following technological scheme: a kind of triple seal bellows stop valve; Comprise upper valve body, following valve body places down the flap in the valve body; The valve rod that runs through upper valve body and be fixedly connected with flap with place the bellows that is sleeved in the upper valve body on the valve rod, it is characterized in that: the contact position is provided with stuffing box on valve rod and upper valve body; And the upper end of bellows is welded on the stuffing box; And the lower end of bellows and valve rod weld together; Said valve rod and contact position, upper valve body lower end also are provided with stuffing box.
Above-mentioned go up stuffing box also be provided with one with upper valve body between adopt bolt to cooperate last stuffing box gland.
Above-mentioned stuffing box down comprises and the lower cover of integrated packing cavity in upper valve body lower end and shutoff packing cavity, is provided with dish spring, dish spring abutment, filler seat and filler in the said packing cavity.
Lock through the tightening backing-up screw between said lower cover and the upper valve body.
Set gradually the triple seal structure in the utility model upper valve body from top to bottom:
The first resealing structure promptly is provided with stuffing box, auxiliary seal at valve rod and contact position, upper valve body upper end; Main effect is after bellows uses destruction for a long time, as the compensation of emergent sealing of short time, in case after bellows damages; Can compress packing seal temporarily, avoid medium to leak.
The second resealing structure; Be provided with one sylphon seal in mid-stent; The upper end that is bellows is welded on the stuffing box; The lower end and the valve rod of bellows weld together, and form a space that isolates fully with the external world, reach valve lumen medium and can not leak into the valve outside. guaranteed the safe handling of valve
The triple seal structure; Promptly stuffing box once is set at valve rod and contact position, upper valve body lower end; Can effectively prevent particulate matter in the medium from getting in the bellows cavity and damage the problem of bellows, thereby effectively prolong and increase the normal working life of bellows.
The advantage of the utility model is: the triple seal bellows stop valve that the utility model provided can bear the operating mode that dust, impurity are arranged in the medium.Can improve the applying working condition of bellows, effectively prolong the working life of bellows, and reach the prolongation valve purpose in working life.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the utility model triple seal structure.
Among the figure: 1. upper valve body; 2. descend valve body; 3. flap; 4. valve rod; 5. bellows; 6. go up stuffing box; 7. descend stuffing box; 8. bolt; 9. go up stuffing box gland; 10. packing cavity; 11. lower cover; 12. dish spring; 13. dish spring abutment; 14. filler seat; 15. filler; 16. tightening backing-up screw.
Embodiment
Below we will combine accompanying drawing that the utility model is further described.
As shown in Figure 1, a kind of triple seal bellows stop valve comprises upper valve body 1; Following valve body 2 places down the flap 3 in the valve body 2, runs through upper valve body 1 and the valve rod 4 that is fixedly connected with flap 3 and place the bellows 5 that is sleeved in the upper valve body 1 on the valve rod 4; Be provided with stuffing box 6 in valve rod 4 and contact position, upper valve body 1 upper end, last stuffing box 6 also be provided with one with upper valve body 1 between the last stuffing box gland 9 that cooperates of employing bolt 8, can regulate stuffing box gland 9 through this bolt 8; Make it press filler at any time; Purpose is to prevent to damage after bellows 5 long-term the uses, in case the provisional measures of setting up. leak, can compress filler and avoid dielectric leakage.The upper end of bellows 5 is welded on the stuffing box 6; And the lower end of bellows 5 and valve rod 4 weld together, and form a space that isolates fully with the external world, reach valve lumen medium and can not leak into the valve outside, have guaranteed the safe handling of valve.Valve, 4 with contact position, upper valve body 1 lower end also be provided with stuffing box 7.As shown in Figure 2, following stuffing box 7 comprises and the lower cover 11 of integrated packing cavity 10 in upper valve body 1 lower end and shutoff packing cavity 10, is provided with dish spring 12, dish spring abutment 13, filler seat 14 and filler 15 in the packing cavity 10; Through 16 lockings of tightening backing-up screw, compress filler 15 to be used for regulating between lower cover 11 and the upper valve body 1, filler 15 can produce distortion under the effect of lower cover 11; It holds valve rod 4 tightly tightly; Realize sealing, prevent that effectively dust and impurity from entering in bellows 5 cavitys, thereby protection bellows 5 exempts from damage; Because in design, added dish spring 12; So after filler 15 wearing and tearing, can compensate automatically through the elastic force of dish spring 12 and compress filler 15, need not manual work and compress filler again.
