Abstract
The utility model relates to an explosion venting valve comprising an air pipe, screws, fixed plates and a cover plate. Reinforcing ribs are welded to the periphery of the air pipe uniformly, the screws are installed on the reinforcing ribs; round plates are welded to the upper ends of the screws; the fixed plates are mounted on the screws in a sleeving manner; springs are mounted between the fixed plates and the round plates; the cover plate is fixed above the air pipe through the fixed plates. The explosion venting valve is simple in structure, good in sealing performance and highly practical.
Description
Technical field
The utility model relates to coating equipment field, relates in particular to a kind of explosion-released valve.
Background technique
Under abnormal condition, combustion barrel internal pressure is too high, easily causes blast, so venting of dust explosion mouth need be set in combustion barrel, former venting of dust explosion mouth is in hot blast stove inner side, and sealing is poor, there is the insufficient gas of a small amount of burning in drying room, be placed on outside, do not have leakage problem.
Model utility content
The utility model provides a kind of and solves that sealing is poor, the explosion-released valve of easy leakage problem.
The technological scheme that the utility model addresses the above problem is:
A kind of explosion-released valve, comprise airduct, screw rod, fixed plate and cover plate, outside described airduct surrounding, uniform welding has stiffening rib, described screw rod is arranged on stiffening rib, and screw rod upper end is welded with plectane, and described fixed plate is sleeved on screw rod, between described fixed plate and plectane, be provided with spring, described cover plate is fixed on airduct top by fixed plate, and when cylinder pressure is normal, cover plate plays seal action; When cylinder pressure is excessive, cover plate can be by pressure jack-up, and when pressure recovers normal, cover plate can be kept in the center.
On the basis of technique scheme, the utility model can also be done following improvement,
Further, described airduct upper end is provided with seal groove, between described seal groove and cover plate, is provided with stuffing box packing;
Further, described stuffing box packing is ceramic fiber.
The beneficial effects of the utility model are:
1. air pressure that can control combustion cylinder inside by spring and fixed plate;
2. utilize seal groove and stuffing box packing can effectively increase the sealing of device;
3. this utility structure is simple, easy to operate, practicability is high.
Accompanying drawing explanation
Fig. 1 is the plan view of a kind of explosion-released valve described in the utility model specific embodiment 1;
Fig. 2 is the plan view of a kind of explosion-released valve described in the utility model specific embodiment 1;
In accompanying drawing, the list of parts of each label representative is as follows:
1, airduct, 2, cover plate, 3, stiffening rib, 4, screw rod, 5, plectane, 6, fixed plate, 7, spring, 8, seal groove, 9, stuffing box packing.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of explosion-released valve, comprise airduct 1, screw rod 4, fixed plate 6 and cover plate 2, described airduct 1 surrounding uniform welding has stiffening rib 3, described screw rod 4 is arranged on stiffening rib 3, and screw rod 4 upper ends are welded with plectane 5, described fixed plate 6 is sleeved on screw rod 4, between described fixed plate 6 and plectane 5, be provided with spring 7, described cover plate logical 2 is crossed fixed plate 6 and is fixed on airduct 1 top, described airduct 1 upper end is provided with seal groove 8, between described seal groove 8 and cover plate 2, be provided with stuffing box packing 9, described stuffing box packing 9 is ceramic fiber;
When cylinder pressure is normal, cover plate 2 plays seal action; When cylinder pressure is excessive, cover plate 2 can be by pressure jack-up, when pressure recovers normal, cover plate 2 can be kept in the center, can utilize like this pressure in spring control combustion cylinder, because airduct 1 surrounding is evenly provided with screw rod 4, can guarantee that like this cover plate 2 can deviation position.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. an explosion-released valve, it is characterized in that, comprise airduct, screw rod, fixed plate and cover plate, outside described airduct surrounding, uniform welding has stiffening rib, described screw rod is arranged on stiffening rib, and screw rod upper end is welded with plectane, and described fixed plate is sleeved on screw rod, between described fixed plate and plectane, be provided with spring, described cover plate is fixed on airduct top by fixed plate.
2. a kind of explosion-released valve according to claim 1, is characterized in that, described airduct upper end is provided with seal groove, between described seal groove and cover plate, is provided with stuffing box packing.
