Technical field
The present invention relates to a kind of superconduction from open-close type pressure-relief explosion-proof door, belong to field of explosion.
Background technique
At present as being all provided with explosion proof door in colliery, thermal power plant, chemical plant, ordnance factory, totally enclosed type air cooling cooling tower system.And this place's temperature is high, sealing difficulty large, open quick-fried rear return weak effect, and storage inflammable and explosive in numerous material and speciality is the most special, if deal with Ignition Phenomena of very easily blasting improperly.The safety problem of these sealed storage equipment will cause the extensive attention of professional person, and superconduction is that a visual plant can escort for safe operation from open-close type safety relief flameproof apparatus.
Mainly there is sealing effect difference in the safety relief flameproof apparatus that current colliery, thermal power plant, chemical plant use, frequent misoperation, opens detonation pressure power and can not regulate the great knotty problems such as accurate, had a strong impact on production.201220233966.6 it is a kind of from open-close type safety relief flameproof apparatus that a number patent of invention carries arch.The shortcoming of this device is: guiding difference causes return normally not complete, and causes opening quick-fried rear generation screens phenomenon, causes on-the-spot paralysis, even parking accident occurs; Three seals is difficult to work simultaneously, and sealing effect is poor, frequent wrong report, leakage, has a strong impact on and produces and not environmentally, bring sizable harm to production and attendant; Suction cup carrier is level, easily assembles coal dust, more easily forms blast area.
Summary of the invention
The present invention seeks to solve that the guiding difference that exists in existing invention causes that return can not normally complete, sealing effect is poor, Initiation Pressure accurately can not regulate and cause reporting by mistake and the problem of inflammable and explosive medium leakage, the present invention discloses a kind of superconduction from open-close type pressure-relief explosion-proof door.
The object of the invention is to be achieved through the following technical solutions.
The present invention discloses a kind of superconduction from open-close type pressure-relief explosion-proof door, comprises link, delivering pipe, return spring, middle guide rod, valve gap, permanent magnet, main sucker, accessory sucker, force adjustment nut, guide cylinder, suction cup carrier and Stamping Steel Ribbon.
Link is the cylindrical structure of hollow, is inverted cone-shaped structure inside upper end; Link lower end is communicated with delivering pipe;
Valve gap is hollow disc shape structure, and lower end outside is taper, is connected with the upper end of link, and joint forms taper exhaust passage; Exhaust passage is distributed with Stamping Steel Ribbon in taper;
Middle guide rod is elongate column metallic rod structure; Return spring is fixedly connected with valve gap through middle guide rod, and the other end is fixedly connected with suction cup carrier; Middle guide rod upper end is successively through suction cup carrier, main sucker, accessory sucker, force adjustment nut; Permanent magnet is fixedly mounted on main sucker;
Guide cylinder is the barrel-like structure of hollow, and upper end is flexibly connected with suction cup carrier; Guide cylinder lower end inside is connected with valve gap, and outside and link utilize bolt to be connected;
Suction cup carrier is frustum structure; Frustum top has groove, places permanent magnet, main sucker, accessory sucker and force adjustment nut in groove;
When pressure release is detonated, accessory sucker is along with valve gap, the pressure release and return spring detonates of middle guide rod pressure, and carry out return pretension by the magnetic force of return spring elastic force and permanent magnet during return, whole machine is integrally constituted.
Working procedure:
When container inner pressure reaches magnetic pretightening force, guide rod, accessory sucker upwards action in the middle of valve gap drives, thorough venting of dust explosion, in the process compression retracteding position spring, and permanent magnet is separated; When after the earth pressure release in delivering pipe to setting value, under the elastic force of return spring and the magnetic force of permanent magnet, realize the return of valve gap; When arriving return position, under permanent magnet magnetic effect, the pretightening force of explosion proof door finally gets back to initial value.
Beneficial effect:
1, superconduction of the present invention is from open-close type pressure-relief explosion-proof door, and adopt the cylindric guide cylinder by face structure to make accurate positioning, lead smooth and easy, can not get stuck phenomenon, prevents the generation of on-the-spot paralysis and parking accident;
2, superconduction of the present invention is from open-close type pressure-relief explosion-proof door, and adopt the design of twice inclined-plane sealing to interfere less each other, sealing can be made more stable, and effect is more obvious;
3, superconduction of the present invention is from open-close type pressure-relief explosion-proof door, and suction cup carrier adopts the design of cone structure, makes structure firmer on the one hand, also makes explosion-proof effect more stable on the other hand, not easily assembles coal dust, make product more reliable.
