Referring to fig. 1-5, the present invention provides an embodiment: the utility model provides a high security is let out and is exploded valve, including valve body 1, fixedly connected with fan 2 in the through-hole of 1 top of valve body, the bottom fixedly connected with master gear 11 of the inside drive shaft of

fan

2, 1 top inner wall medial position of valve body rotates at the rear of master gear 11 and is connected with

bull stick

10, 10 outside middle side fixedly connected with pinion 7 of bull stick, 7 outside front end meshing of pinion is connected at the outside rear end of

master gear

11, 10 bottom fixedly connected with first sprocket 13 of bull stick, 1 inside upside fixedly connected with of valve body is explosion-proof net 9, fixedly connected with bearing 12 in the through-hole at 9 top centers of explosion-proof net, the inside fixedly connected with pivot 15 of

bearing

12, 15 top fixedly connected with second sprocket 14 of pivot, a plurality of explosion-proof boards 8 of leaking of a week of the outside downside of pivot, first sprocket 13 is connected with second sprocket 14 chains.

After dust and sparks enter the valve body 1, the fan 2 is started to blow the dust inside the valve body 1 downwards and drive the air inside the valve body 1 to flow, the main gear 11 is driven to be meshed with the pinion 7 to rotate, the pinion 7 drives the rotating rod 10 to rotate, the rotating rod 10 drives the rotating shaft 15 to rotate through a chain between the first chain wheel 13 and the second chain wheel 14, the fan 2 drives the explosion venting plate 8 which rotates outside when blowing the air inside the valve body 1 to rotate at the uniform speed inside the valve body 1, so that the explosion venting plate 8 can rapidly contact and collide with the sparks, the sparks can rapidly explode inside the valve body 1, the explosion venting purpose is achieved, and the energy consumption of the explosion venting valve is reduced by improving the working efficiency of the explosion venting valve.

Fixedly connected with inlet pipe 3 in the through-hole of the outside left end of valve body 1 for insert dust and mars and get into 1 inside work of exploding of letting out of valve body, main gear 11 diameter is less than pinion 7, drives pinion 7 through the spur gear and rotates and slow down to make inside pivot 15 can drive let explode board 8 and carry out the effect at the uniform velocity pivoted, the ash discharge mouth has been seted up at 1 bottom center of valve body, is used for discharging the dust of 1 inside of valve body.

Fixedly connected with explosion venting pipe 4 in the through-hole of the outside right-hand member of valve body 1, explosion venting pipe 4 inside inboard fixedly connected with spacing ring 16, 16 left end fixedly connected with springs 17 of spacing ring, 17 left end fixedly connected with does not have

flame board

18, 18 outside sliding connection of no flame board is in explosion venting pipe 4's inside left side, explosion venting pipe 4 outside is located a plurality of exhaust holes 5 have all been seted up to spacing ring 16's right side a week, explosion venting pipe 4 right-hand member upside rotates and is connected with

guard plate

6, 6 similar semi-circles of guard plate, guard plate 6 is the same with explosion venting pipe 4 diameters.

When explosion venting is carried out inside the valve body 1, impact force during explosion applies pushing acting force to the flameless plate 18, the stressed flameless plate 18 is decelerated through the limiting ring 16 in cooperation with the spring 17, damage to the joint of the explosion venting pipe 4 and the valve body 1 caused by the impact force during explosion is reduced, and the purpose of cracking or loosening is prevented, flame generated during explosion is converted into gas by the flameless plate 18 and is exhausted through the exhaust holes 5, wherein the working principle of the flameless plate 18 is similar to that of a flameless inclined plate in the prior art, the flameless inclined plate has the function of rapidly converting the flame into smoke and has a good protection effect, when the impact force of the gas is overlarge, the gas can impact the protection plate 6, the gas circularly flows in the explosion venting pipe 4 through the radian inside of the protection plate 6 and is exhausted through the exhaust holes 5, and therefore the high safety of the explosion venting valve is improved by prolonging the service life of the explosion venting pipe 4.

The working principle is as follows: when dust and sparks enter the valve body 1, the fan 2 is started to blow the dust inside the valve body 1 downwards and drive air inside the valve body 1 to flow, the main gear 11 is driven to be meshed with the pinion 7 to rotate, the pinion 7 drives the rotating rod 10 to rotate, the rotating rod 10 drives the rotating shaft 15 to rotate through a chain between the first chain wheel 13 and the second chain wheel 14, the fan 2 blows air inside the valve body 1 and drives the explosion venting plate 8 rotating outside to rotate at a constant speed inside the valve body 1, so that the explosion venting plate 8 can quickly contact and collide with the sparks, the sparks can quickly explode inside the valve body 1, the explosion venting purpose is completed, the work efficiency of the explosion venting valve is improved, the energy consumption of the explosion venting valve is reduced, when explosion venting is performed inside the valve body 1, the impact force during explosion exerts pushing force on the flameless plate 18, the stressed flameless plate 18 is decelerated through the limiting ring 16 and the spring exhaust hole, the impact force generated when the explosion venting valve is used for reducing the damage of the impact force on the joint of the explosion venting pipe 4 and the vent pipe 4 and the valve body 1, preventing cracks or generating loose gas, the gas generated when the explosion venting through the explosion venting hole 6, the explosion venting pipe, the explosion venting hole can be used for prolonging the life of the explosion protection plate, and the gas generated by the explosion protection plate, and the gas can be discharged through the explosion.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
