Description
Technical field
The utility model relates to a kind of explosion venting valve, specifically a kind of weighting heart self-closing secondary seal with warning function
Explosion venting valve.
Background technique
In flammable explosive gas or combustible dust purification system, needed when designing deduster, process equipment or pipeline
Consider setting explosion venting valve.When generation explosion time, venting of dust explosion film off-load damaged first, so that important equipment be protected to be not subjected to damage.Often
With occasion include coal-gas recovering, coal powder collection, coal removing dirt, cement plant kiln tail dedusting, aluminium powder magnesium powder is gathered dust, coke-stove gas removes
Dirt, dedusting of blast furnace gas, mineral hot furnace flue gas cleaning etc. are related to multiple industries such as electric power, building materials, steel, chemical industry.
Conventional explosion venting valve mainly has simple type, Weight type and spring.Simple type valve body is rounded or rectangular, and one end has
Flange, venting of dust explosion film are fixed on flange by pressing plate, no door closure, and venting of dust explosion film is damaged after venting of dust explosion, are leaked out serious.Weight type valve body
Lower part is identical as simple type, increases adapter tube and door closure above venting of dust explosion film, a weight is configured on door closure, can be extensive after venting of dust explosion
It is multiple, it is compressed by weight, since only one weight is pressed among door closure, with the increase of number of use, door closure can be because of stress not
It uniformly deforms, sealing effect is bad, and furthermore structure is complicated, weight is heavy.The lower part of spring valve body also with simple type
It is identical, a door closure is increased above venting of dust explosion film, by spring compression between door closure and lower valve body, explosion time venting of dust explosion film is damaged,
Air-flow, which is gone out, jacks up off-load for spring.Spring explosion venting valve is not easy to replacement venting of dust explosion film, and practical operation is possible to that venting of dust explosion is not achieved
Effect, if be more than spring yield limit when can not restore, be easy to cause leakage.Under normal circumstances, explosion venting valve alarm free fills
Set, venting of dust explosion film is damaged after venting of dust explosion, only manually inspection just it can be found that repairing not in time.
Therefore, it is necessary to design a kind of novel explosion venting valve, function was sounded an alarm when both can satisfy venting of dust explosion, to work
Personnel come to repair in time, and can be with self reset and fast sealing after venting of dust explosion.
Utility model content
The purpose of this utility model be exactly in order to can not alarm when solving existing explosion venting valve venting of dust explosion and self reset after seal
Not tight problem provides a kind of weighting heart self-closing secondary seal explosion venting valve with warning function, venting of dust explosion both may be implemented
When sound an alarm, to repair venting of dust explosion film in time, and can be resetted with self after venting of dust explosion, be sealed simultaneously, to carry out secondary close
Envelope, prevents from revealing.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of weighting heart self-closing secondary seal explosion venting valve with warning function, including upper valve body and lower valve body, lower valve
Body upper end and upper valve body lower end are equipped with flange, are equipped with venting of dust explosion film between flange；Upper and lower valve body is connected by the bolt on flange
It connects.The top of upper valve body is equipped with valve deck, it is characterised in that:
Upper valve body outer wall is equipped with support frame, and valve deck is equipped with cursor, is equipped with pin shaft in the middle part of cursor, pin shaft with it is described
The middle and upper part of support frame is connected, and cursor can be formed with support frame and is rotatably assorted.
Support frame upper end is equipped with limited block, and limited block can form limit cooperation with the top of cursor；
A travel switch is equipped with below support frame, travel switch can form opening and closing cooperation with the lower end of cursor.
Travel switch is connected by conducting wire with alarm.
Protective net is equipped in upper valve body above venting of dust explosion film, to prevent flying out after the quick-fried film breakage of stopping leak.
Valve deck inner face is equipped with magnetic sealing strip.
In the technical solution of the utility model, valve deck is flicked when venting of dust explosion, since the cursor on valve deck is by limited block
Blocking, valve deck can under the action of center of gravity self reset, and magnetic sealing strip design but also reset after explosion venting valve can
To carry out secondary seal；In addition, be connected using travel switch with alarm, when valve deck is flicked, cursor lower end touching row
Cheng Kaiguan imparts warning function of the explosion venting valve in venting of dust explosion, convenient for discovery venting of dust explosion situation, replaces venting of dust explosion film in time, ensure that
The normal use of subsequent explosion venting valve.
Detailed description of the invention
Fig. 1 is state when a kind of weighting heart self-closing secondary seal explosion venting valve with warning function of the utility model works
Figure；
State when Fig. 2 is a kind of weighting heart self-closing secondary seal explosion venting valve venting of dust explosion with warning function of the utility model
Figure.
Specific embodiment
In order to which the utility model is more clearly understood, there is alarm function to one kind of the utility model with reference to the accompanying drawing
The weighting heart self-closing secondary seal explosion venting valve of energy further illustrates that specific embodiment described herein is only used to explain this
Utility model is not used to limit the utility model.
A kind of weighting heart self-closing secondary seal explosion venting valve with warning function, including upper valve body 2 and lower valve body 1, under
1 upper end of valve body and 2 lower end of upper valve body are equipped with flange 5, are equipped with venting of dust explosion film 4 between flange 5, upper valve body 2 and lower valve body 1 pass through method
Bolt 6 on orchid 5 connects.The top of upper valve body 2 is equipped with valve deck 3, it is characterised in that:
2 outer wall of upper valve body is equipped with the support frame 14 of a L-type.
3 one end of valve deck is equipped with cursor 8, is equipped with pin shaft 11, the middle and upper part phase of pin shaft 11 and support frame 14 in the middle part of cursor 8
Even, cursor 8 is rotatably assorted with the composition of support frame 14.
14 upper end of support frame is equipped with limited block 10, and the top formation limit cooperation of limited block 10 and cursor 8 is let out with limitation
The valve deck 3 bounced when quick-fried only center of gravity.
A travel switch 9, the lower end formation opening and closing cooperation of travel switch 9 and cursor 8, row are equipped with below support frame 14
Cheng Kaiguan 9 is connected by conducting wire with alarm 13.
It is equipped with protective net 7 in the upper valve body 2 of 4 top of venting of dust explosion film, to prevent flying out after the quick-fried film breakage of stopping leak.
3 inner face of valve deck is equipped with magnetic sealing strip 12, plays the role of secondary seal, anti-leak.
When venting of dust explosion, venting of dust explosion film 4 ruptures, and valve deck 3 is bounced, and the cursor 8 on valve deck 3 is rotated centered on pin shaft 11, when
When reaching certain position, 8 lower end crush stroke switch 9 of cursor, so that the alarm 13 being connected with travel switch 9 starts to report
It is alert.Further, since restriction effect of the top of cursor 8 by limited block 10, valve deck 3 is fallen by self gravity, by valve body
It covers.Magnetic sealing strip 12 is equipped in valve deck 3 under the double action of 3 gravity of magnetic force and valve deck, to reach after valve deck 3 is fallen
The purpose of secondary seal avoids pollution to effectively prevent coal gas or pernicious gas largely leaks after venting of dust explosion.
