Abstract
The invention relates to the field of gas transmission and distribution protection boxes, in particular to an explosion-proof pressure regulating box which comprises a box, a box cover and connecting rods. Limiting stoppers are arranged on the inner wall of the box, through holes are formed in the limiting stoppers, the connecting rods penetrate the through holes to be connected with the box cover, limiting components are arranged at the ends of the connecting rods, and elastic components which can be compressed by the limiting components and the limiting stoppers are arranged between the limiting components and the limiting stoppers. The explosion-proof pressure regulating box has the advantages that the explosion-proof pressure regulating box is provided with the connecting rods, so that the box can be connected with the box cover in a semi-movement manner, the box cover can face upwardly under the effect of impact force of gas when explosion occurs in the box, springs can be compressed, gaps between the box and the box cover can be enlarged, and the gas can be exhausted from the gaps between the box cover and the box; the gas further can be exhausted from a plurality of exhaust holes which are formed in the upper portions of two sides of the box, and accordingly the impact force which is exerted on the box by the gas can be cushioned.
Description
Technical field
The present invention relates to gas transmission and distribution protection cabinet field, particularly the explosion-proof pressure regulation casing of one.
Background technique
The regulator that is conducted through of combustion gas carries out pressure adjustment, and this regulator needs a kind of casing and protects it, because rock gas has inflammable, explosive, needs pressure regulation casing to have the ability of quick pressure releasing.The casing of existing pressure-regulating box comprises box-like body and case lid, and case lid is fixedly connected with box-like body by bolt.If blasted, gas impacts casing and case lid, cannot in time, quick drain goes out, even case lid can overall flying out, and causes the loss of the aspect such as the person, property.
Summary of the invention
The object of this invention is to provide a kind of explosion-proof pressure regulation casing, when box house is blasted, energy quick pressure releasing, and certain buffer function is played to gas impact.
Technological scheme of the present invention is as follows: explosion-proof pressure regulation casing, comprise casing and case lid, the inwall of described casing is provided with limiting stopper, described limiting stopper is provided with through hole, also comprise connecting rod, described connecting rod is connected with described case lid through described through hole, and the end of described connecting rod is provided with limit position part, is provided with the elastic component compressed by described limit position part and described limiting stopper between described limit position part and described limiting stopper.
Described casing two upper lateral part is provided with multiple exhaust port.Described case lid can be reverse V-shaped, ramp type, horizontal type etc.The both sides of described case lid are provided with bending part, and described bending part and described casing outer upper are that face contacts.Described limit position part is cotter pin.Described elastic component is spring.
The present invention is by arranging connecting rod, casing and case lid half are flexibly connected, if blasted in casing, the impact force of gas makes case lid upwards, spring-compressed, and the gap between casing and case lid becomes large, gas emits from the gap between case lid and casing, multiple exhaust port discharges that can also be arranged by casing two upper lateral part, like this, gas will be cushioned the impact force of casing.When the pressure releasing of inside is to after rational pressure, case lid, under the elastic force acting in conjunction of self gravitation and spring, returns to origin-location, plays original protective action.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is stereogram of the present invention;
Fig. 4 is the partial enlarged drawing in the A portion in Fig. 3.
Embodiment
As depicted in figs. 1 and 2, explosion-proof pressure regulation casing of the present invention, comprises casing 1 and case lid 2, case lid 2 is reversed V-shape, the inwall of casing 1 is provided with limiting stopper 3, and limiting stopper 3 is fixedly connected with casing 1 by bolt, and limiting stopper 3 is provided with through hole, also comprise connecting rod 4, connecting rod 3 is connected with case lid 2 through through hole, and the end of connecting rod 3 is provided with pin-and-hole, is provided with cotter pin 8 in pin-and-hole, between the upper surface of cotter pin and casing 1, be provided with spring 4, cotter pin is used for preventing spring 5 from dropping.The both sides of case lid 2 are provided with bending part 6, and bending part 6 and casing 1 outer upper are that face contacts, and which reduce the area of contact of case lid and casing, are convenient to case lid and move up, increase displacement distance.Casing 1 liang of upper lateral part is provided with multiple exhaust port 7.
When blasting in casing 1 inside, produce a large amount of gas, gas impacts casing 1, and connecting rod 4 upwards pushes up, spring 5 compresses, case lid 2 is upwards lifted, and the gap between casing 1 and case lid 2 becomes large, and most of gas emits between the gap between casing 1 and case lid 2, the both sides of casing 1 also have multiple exhaust port 7, after case lid 2 is up lifted, the kink 6 of case lid 2 upwards moves, and gas can also be discharged casing 1 from exhaust port 7.Casing 1 of the present invention and case lid 2 are half flexible connection, and when blasting in casing 1 inside, casing 1 can play certain buffer function to the impact of gas.
When casing 1 internal pressure is released to rational safety pressure, case lid 2, under the acting in conjunction of the gravity of self and the elastic force of spring 5, returns to original position, plays original protective action.
