The utility model discloses reform transform current boiler explosion vent, reduce boiler equipment accident, avoid boiler brickwork and equipment to damage, extension equipment life.
Description
Technical Field
The utility model belongs to the technical field of the boiler, specifically a boiler explosion vent.
Background
The inclined explosion-proof door is opened when the boiler has combustion failure, so that equipment accidents are avoided. Because of explosion vent weight and angle reason, the explosion vent can not effectively be opened in actual operation, reforms transform boiler explosion vent now, reduces boiler equipment accident, avoids boiler furnace wall and equipment to damage, extension equipment life. The weight of the original explosion door cover reaches 25kg, the opening sensitivity is seriously influenced, and the boiler is often damaged due to the combustion accident of the boiler.
Disclosure of Invention
In order to solve the problem, the utility model discloses an open sensitivity height, and open the boiler explosion vent that pressure energy adjusted.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
the utility model provides a boiler explosion vent, includes door frame, door closure, door-hinge, two counter weights and fixing bolt, the door-hinge rotates to be fixed in on two connecting pieces on the door frame, the door closure is fixed in through connecting portion above that the door-hinge is last, the both ends of door-hinge are equipped with the external screw thread of certain length, every one is installed to the one end of door-hinge the counter weight, every the counter weight is through two fixing bolt is fixed in on the door-hinge.
Preferably, the counterweight is of a water-drop-shaped structure, a connecting through hole is formed in the upper portion of the counterweight, and the connecting through hole is connected with the door spindle.
Preferably, the counterweight is composed of a plurality of drop-shaped counterweight units, and the number of the drop-shaped counterweight units can be increased or decreased according to production needs.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. the utility model reforms the existing boiler explosion door, reduces the boiler equipment accident, avoids the boiler wall and the equipment damage, prolongs the equipment service life;
2. the utility model discloses alleviateed the weight of door, then at the epaxial installation counter weight of door, can be according to actual pressure release demand increase and decrease drop shape counter weight unit, ensured the rationality of pressure release.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. In the drawings:
FIG. 1 is a front view of the present invention;
