Side wall be equipped with elastic spacing pin 82, and elastic spacing pin 82 towards 5 side of valve deck be inclined-plane, backwards to 5 side of valve deck and locked groove
81 side walls are vertical.After venting of dust explosion, valve deck 5 falls reset under the effect of gravity, when convex block 7 is moved at locked groove 81 with elastic spacing pin
82 downthrusts, and pushed back in 81 side wall of locked groove, convex block 7 is able to pass through and be embedded in locked groove 81, at this time elastic spacing
Pin 82 pops up again, and convex block 7 is lockked, so that valve deck 5 and lower gripper 3(is referring to Fig. 1) end face fit closely.
As shown in Fig. 2, being equipped with buffer spring 84,84 one end of buffer spring and locked groove 81 between 81 bottom of locked groove and convex block 7
Bottom is affixed, and the other end offsets with convex block 7.Convex block 7 elastic spacing pin 82 is pushed back in 81 side wall of locked groove during with buffering
Spring 84 touches, and kinetic energy is converted into the elastic potential energy of buffer spring 84, reduces when valve deck 5 resets and 3 end face of lower gripper
Between impact, avoid valve deck 5 acutely rebound cause convex block 7 to be deviate from out of locked groove 81.
As shown in Fig. 2, 81 bottom of locked groove is embedded with magnet 83, convex block 7 is made of ferrimagnet.The insertion lock of convex block 7
It is adsorbed after slot 81 by magnet 83, so that valve deck 5 is collided convex block 7 when springing back with 3 end face of lower gripper and be not easy to deviate from out of locked groove 81.
As shown in figure 3, unlocking mechanism 9 includes the cylindrical drive rod 91 being arranged in below venting of dust explosion valve body 1, drive rod 91
It is arranged along 1 length direction of venting of dust explosion valve body, including sleeve 911 and slide bar 912, sleeve 911 and upper clamper 2 are hinged, slide bar 912
One end is slidably arranged in sleeve 911, and the other end passes through closing piece 8 and elastic spacing pin 82(referring to fig. 2) it is affixed, it is opened on closing piece 8
Equipped with the sliding slot 85 that can hold the sliding of drive rod 91.Drive rod 91 rotates under outer power drive around hinged end, and moves backwards to locked groove 81
When dynamic, referring to fig. 2 towards elastic spacing pin 82() one end is slided in sliding slot 85, and drives elastic spacing pin 82(referring to figure
2) retract 81 side wall of locked groove, make convex block 7(referring to fig. 2) be able to be detached from out of locked groove 81, valve deck 5 can be with smooth opening.
As shown in figure 4, upper 2 inner wall bottom of clamper opens up fluted 92, flexible sheet 93 is equipped at the top of groove 92,
Bottom offers through-hole 94, and pressure ram 95 is equipped in through-hole 94, and 95 one end of pressure ram is connected with flexible sheet 93, and the other end is set
It is set to taper, is offseted positioned at sleeve 911 towards 81 side of locked groove and with sleeve 911.When gas filtering system 10(is referring to Fig. 1) in
Explosion time occurs, air pressure increases in upper clamper 2, and flexible sheet 93 is pressed towards 92 bottom of groove, thus by pressure ram 95 from logical
Release in hole 94, pressure ram 95 then squeezes sleeve 911, and then with moving slide-bar 912(referring to Fig. 3) backwards to locked groove 81(referring to Fig. 3)
Rotation.
As shown in figure 4, flexible sheet 93 is equipped with slow pressing plate 96 towards 95 side of pressure ram, it is solid with pressure ram 95 to delay pressing plate 96
Connect, avoid flexible sheet 93 by pressure ram 95 release when, because the two contact area is too small, stress concentration cause flexible sheet 93 by
Damage.
Specific implementation process:
After exploding in gas filtering system 10, air pressure is increased in upper clamper 2, and flexible sheet 93 is pressed towards groove 92
Pressure ram 95 is released in bottom, and then squeezes drive rod 91, rotates it backwards to locked groove 81, and elastic spacing pin 82 is driven to contract
81 inner wall of locked groove is returned, so that convex block 7 is no longer limited by closing piece 8, rupture disk 4 ruptures at this time, and valve deck 5 is opened, moment pressure release.Venting of dust explosion
Valve deck 5 is fallen naturally by gravity afterwards, and convex block 7 collides with elastic spacing pin 82, is pushed back in 81 side wall of locked groove, suitable
Benefit insertion locked groove 81, then elastic spacing pin 82 stretches out again, and convex block 7 is lockked, and valve deck 5 is closely pasted with 3 end face of lower gripper
It closes, venting of dust explosion valve body 1 is sealed.
Embodiment 2: a kind of explosion venting valve of self-sealing, difference from example 1 is that, as shown in figure 5, elastic spacing
Pin 82 is also configured as inclined-plane backwards to 5 side of valve deck, and tilt angle is less than the other side.Valve deck 5 is because in venting of dust explosion valve body 1 when venting of dust explosion
Portion's pressure is excessive and mobile backwards to lower gripper 3, and convex block 7 is driven to squeeze elastic spacing pin 82, is pushed back 81 side wall of locked groove
It is interior, so that convex block 7 is detached from out of locked groove 81.
The above embodiments are only the explanation to the utility model, are not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
