Abstract
The utility model provides a glasses valve for a vertical pipeline, which comprises a left valve body, a valve plate, a valve seat, sealing rings and a guide rail. The guide rail is fixed at the outer side of the valve plate, the sealing rings which are sealed with the valve seat are arranged at the two sides of the valve plate, and three top rod mechanisms are arranged at the position on the left valve body corresponding to the guide rail; each top rod mechanism is composed of a fixed sleeve, a top rod, a rolling wheel and a pin shaft; the fixed sleeve is fixedly arranged on the left valve body, a thread is arranged at the left end of the top rod, the top rod is arranged in the fixed sleeve, a nut is fixed at the left end of the top rod, and the rolling wheel which is arranged at the head part of the top rod is fixed on the top rod by the pin shaft. The distance between the rolling wheel and the guide rail is half of the separating distance of the valve plate. The glasses valve has the following beneficial effects: the adoption of the top rod mechanisms can make sure that the clearance of the valve plate separating from the valve seat is the same when the valve plate is loosened, and abrasion cannot occur between the sealing rings of the valve plate and the valve seat when the valve plate is in walking, thereby prolonging the service life of the glasses valve.
Description
Technical field
The utility model relates to a kind of valving, especially a kind of vertical pipe glasses valve at iron and steel enterprise's coal gas system.
Background technique
At present the metallurgy industry gas pipe line all is that glasses valve is installed on horizontal pipe, drives the valve plate walking by feathering axis, with reach valve switch from.Under general condition, this structure can reach the needed technological requirement of gas pipe line.But,, glasses valve need be installed on vertical pipe along with the automaticity application is more and more higher.The valve plate of the glasses valve that level is installed is because can only rotate perpendicular to horizontal plane, if do to horizontally rotate,, influence seal ring working life not only because the direct friction between valve plate and the valve seat, cause the leakage of valve, cause environmental pollution and harm personnel's safety.
Summary of the invention
For the glasses valve that overcomes existing structure can not use deficiency on vertical pipe, the utility model provides a kind of vertical pipe glasses valve.
The technological scheme that its technical problem that solves the utility model adopts is a kind of vertical pipe glasses valve, comprise left valve barrel, valve plate, valve seat, seal ring, guide rail, guide rail is fixed on the outside of valve plate, seal ring is equipped with in the both sides of valve plate, with valve base sealing, with the guide rail corresponding section three post rod mechanisms are housed also on the left valve barrel, this post rod mechanism is by fixed cover, push rod, roller, bearing pin is formed, fixed cover is fixedly mounted on the left valve barrel, push rod has screw thread at left end, push rod is packed in the fixed cover, left end at push rod is fixed with nut, head at push rod is equipped with roller, and roller is fixed on the push rod by bearing pin, and the distance of roller and guide rail is half of valve plate throw-off distances.
The beneficial effects of the utility model are to adopt post rod mechanism, and when guaranteeing that valve plate unclamps, it is identical that valve plate is thrown off the gap of valve seat, and the seal ring of valve plate can not produce wearing and tearing with valve seat when valve plate is walked, the working life of raising valve.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment;
Among the figure: 1. left valve barrel; 2. nut; 3. fixed cover; 4. push rod; 5. valve plate; 6. seal ring; 7. valve seat; 8. guide rail; 9. roller; 10. bearing pin.
Embodiment
As shown in Figure 1, a kind of vertical pipe glasses valve, comprise left valve barrel 1, valve plate 5, valve seat 7, seal ring 6, guide rail 8, guide rail 8 is fixed on the outside of valve plate 5, seal ring 6 is equipped with in the both sides of valve plate 5, with valve seat 7 sealings, with guide rail 8 corresponding sections three post rod mechanisms are housed also on the left valve barrel 1, this post rod mechanism is by fixed cover 3, push rod 4, roller 9, bearing pin 10 is formed, fixed cover 3 is fixedly mounted on the left valve barrel 1, push rod 4 has screw thread at left end, push rod 4 is packed in the fixed cover 3, is fixed with nut 2 at the left end of push rod 4, at the head of push rod 4 roller 9 is housed, roller 9 is fixed on the push rod 4 by bearing pin 10, and the distance of roller 9 and guide rail 8 is half of valve plate 5 throw-off distances. can regulate distance between roller 9 and the guide rail 8 by nut 2.
