Embodiment Construction

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Such as figure 1 , figure 2 As shown, this embodiment provides a positive pressure explosion-proof box, including:

[0032] The box frame 10 is formed by connecting several skeleton rectangular tubes 101, and at least one movable cover installation opening 102 surrounded by the skeleton rectangular tubes 101 is formed on the box frame 10;

[0033] The rubber strip frame 20 has elasticity and is arranged at the installation opening 102 of the movable cover. The rubber strip frame 20 includes a main body part 201...

Abstract

The invention provides a positive pressure explosion-proof box body and a positive pressure explosion-proof unit, and the box body comprises a box body frame which is provided with a movable cover plate installation port; the rubber strip frame is elastic and is arranged at the movable cover plate mounting opening, and the rubber strip frame comprises a main body part forming the frame, and an outer edge and an inner edge which are arranged on the main body part; the sealing rubber strips are arranged on the outer edge and the inner edge; the number of the movable cover plates is at least one, the movable cover plates are detachably installed outside the movable cover plate installation openings, and after the movable cover plates are installed, the movable cover plates apply pressing force towards the inner side of the box body frame to the rubber strip frame by pressing the inner edges so that the outer edges can be tightly attached to the outer surfaces of the framework rectangular pipes. A first seal is formed between the outer edge and the framework rectangular tube, and a second seal is formed between the movable cover plate and the inner edge.

Description

technical field [0001] The invention relates to the technical field of environmental test chambers, in particular to a positive pressure explosion-proof box and a positive pressure explosion-proof unit. Background technique [0002] Environmental test chambers are necessary testing equipment for aviation, automobiles, home appliances, hydrogen energy, scientific research and other fields. At present, the test chambers used in hydrogen fuel cell tests involving hydrogen energy and aero-engine tests need to use explosion-proof devices, but not all devices in a test equipment can reach the required explosion-proof level, so it is urgent to solve the explosion-proof problems of some devices. need. [0003] At present, there are two conventional explosion-proof methods: explosion-proof and positive-pressure explosion-proof. Explosion-proof is mainly used in air-tight electrical equipment. The casing is sealed by melting, extrusion, and gluing methods to prevent external flammab...
