Abstract
The invention provides a venting explosion valve which comprises a valve body, a valve plate, a guide column, a spring and a sealing ring, wherein one end of the guide column is fixed on the valve body after passing through the valve plate and the other end is provided with a nut and a gasket, the spring is arranged between the gasket and the valve plate, the valve plate is provided with a step, the step is provided with a groove, a distance is arranged between the groove and the bottom plane of the valve plate, and the groove is internally provided with the sealing ring which is sealed with the inner wall of the valve body. The end part of the step of the valve plate is provided with a guide angle, and a bearing is arranged between the valve plate and the guide column. The invention can be used repeatedly without a venting explosion film, needs not to be maintained after the venting explosion, and has low cost and convenient use.
Description
Technical field
The present invention relates to a kind of valve, particularly relate to a kind of explosion-released valve.
Background technique
The explosion-released valve of smelter use at present, by valve body, valve plate, pressing plate, sealing gasket, the venting of dust explosion film, the venting of dust explosion film is housed between valve body and the pressing plate, directional post one end passes valve plate and is fixed on the valve body, the other end is equipped with nut and pad, between pad and the valve plate spring is housed, seal by the seal ring that is loaded on the valve plate bottom plane between valve plate and the valve body, when system pressure during greater than the bursting pressure of venting of dust explosion film, the explosion of venting of dust explosion film, valve plate is replied under the spring force effect behind the venting of dust explosion, prevent that more multimedium leaks, but before new venting of dust explosion film is changed, when needing only system pressure, just there is medium to leak, in addition because the material of venting of dust explosion film greater than valve plate gravity and spring force, thickness deviation brings the inconsistent risk of venting of dust explosion pressure.
Summary of the invention
After overcoming existing explosion-released valve venting of dust explosion, need to change the venting of dust explosion film, and, the invention provides a kind of explosion-released valve that does not need the venting of dust explosion film because material, the thickness deviation of venting of dust explosion film bring the deficiency of the inconsistent risk of venting of dust explosion pressure.
The technical solution adopted for the present invention to solve the technical problems is a kind of explosion-released valve, comprise valve body, valve plate, directional post, spring, seal ring, directional post one end passes valve plate and is fixed on the valve body, the other end is equipped with nut and pad, between pad and valve plate spring is housed, and valve plate has a step, have groove on the step, there is a distance groove and valve plate bottom plane, and seal ring is housed in the groove, with the inner wall sealing of valve body.
There is an angle of deflection end of valve plate step, and bearing also is housed between valve plate and the directional post.
The invention has the beneficial effects as follows does not need the venting of dust explosion film, but the repeatable countless times use, Maintenance free behind the venting of dust explosion, cost is low, and is easy to use.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment;
Fig. 2 is the tectonic maps of prior art
Among the figure: 1. valve body; 2. pad; 3. spring; 4. directional post; 5. valve plate; 6. bearing; 7. seal ring; 8. angle of deflection; 9. pressing plate; 10. sealing gasket; 11. venting of dust explosion film.
Embodiment
As shown in Figure 1, a kind of explosion-released valve, comprise valve body 1, valve plate 5, directional post 4, spring 3, seal ring 7, directional post 4 one ends pass valve plate 5 and are fixed on the valve body 1, and the other end is equipped with nut and pad 2, between pad 2 and valve plate 5, spring 3 is housed, valve plate 5 has a step, has groove on the step, and there is a distance groove and valve plate 5 bottom planes, seal ring 7 is housed, with the inner wall sealing of valve body 1 in the groove.There is an angle of deflection 8 end of valve plate 5 steps, between valve plate 5 and the directional post 4 bearing 6 is housed also.During use, under the system pressure effect, valve plate 5 is along the step segment distance that moves up, when system pressure is elevated to a certain degree, when the active force that spring is produced equates with venting of dust explosion pressure, produce pressure release, after when system pressure is lower than the venting of dust explosion value, valve plate 5 automatically replies under the effect of spring.
Fig. 2 is the prior art tectonic maps, and pressing plate 9 is housed on the valve plate 1, and sealing gasket 10 and venting of dust explosion film 11 are equipped with in the centre, seal ring 7 sealings by being loaded on valve plate 5 bottom planes between valve plate 5 and the valve body 1.When system pressure during greater than the bursting pressure of venting of dust explosion .11,11 explosions of venting of dust explosion film, valve plate 5 is replied under spring 3 active forces behind the venting of dust explosion, prevent that more multimedium leaks, but before new venting of dust explosion film 11 is changed, when needing only system pressure, just there is medium to leak, in addition because material, the thickness deviation of venting of dust explosion film bring the inconsistent risk of venting of dust explosion pressure greater than valve plate 5 gravity and spring force.
Claims (3)
1, a kind of explosion-released valve, comprise valve body, valve plate, directional post, spring, seal ring, directional post one end passes valve plate and is fixed on the valve body, the other end is equipped with nut and pad, between pad and valve plate spring is housed, it is characterized in that: described valve plate has a step, has groove on the step, there is a distance groove and valve plate bottom plane, and seal ring is housed in the groove.
