Explosion-proof accessory multifunctional protection test auxiliary apparatus

Abstract

The invention discloses an explosion-proof accessory multifunctional protection test auxiliary apparatus. The apparatus takes a test casing as a main body, at least one surface of the test casing is outwardly provided with adapters with different dimensions layer by layer in a matched mode, the dimensions of an upper port and a lower port of an intermediate-layer adapter are different, the dimension of one end matches the dimension of an inner-layer adapter or the port of the test casing, the dimension of the other end matches the dimension of an outer-layer adapter, an outermost-layer adapter is connected with a plug, and sealing members are arranged at a connection position between the corresponding adapter and the test casing, between two adapters and between the corresponding adapter and the plug. The explosion-proof accessory multifunctional protection test auxiliary apparatus, as a simulation test box for a protection test, through connection of the casing, the adapters and the sealing members, can be applied to performing the protection test on explosion-proof accessories with different dimensions and different structures, can solve the problems of waste of resources, long test period and the like existing in conventional explosion-proof accessory protection test examination work, and can also be applied to an IPX8 protection diving test of a miniaturized electrical product.

Description

technical field [0001] The invention belongs to the field of explosion-proof equipment, and in particular relates to an auxiliary device for protection tests of explosion-proof accessories. Background technique [0002] At present, explosion-proof stuffing boxes, flexible pipes, threading boxes, isolation sealing boxes, plugs and other explosion-proof accessories are widely used in explosive hazardous places (explosive gas environment or dust environment). site requirements. Explosion-proof accessories are explosion-proof products. According to the requirements of on-site use, the manufacturer designs and manufactures a large number of different sizes and structures, which leads to a difficult problem in the protection inspection of this type of explosion-proof products-it needs to be equipped with explosion-proof accessories according to different sizes and structures. Install protective test auxiliary devices of different sizes (ie simulated protective boxes). Usually th...
