Explosion-proof accessories for use in explosion-proof areas

1. Explosion-proof junction box

It is a special power distribution equipment used in various high-risk places, and a power distribution box with explosion-proof function. It is made of aluminum alloy die-casting, and the surface is electrostatically sprayed; there are two types: increased safety type and explosion-proof type. Built-in wiring terminals, fixedly connect the incoming wires. There are many sizes to choose from. The direction of the inlet can be determined according to the requirements of the user. The specification of the inlet of the junction box is usually an inch pipe thread, and it is equipped with an engineering plastic compression nut, which is used to connect various electrical equipment and instruments in the voltage 220V/380V line. Used for branching and wiring of instruments.

2. Explosion-proof junction box

Cast aluminum alloy shell, surface spraying, beautiful appearance, there are many ways and specifications for the inlet and outlet, there are 4 terminals inside, when opening the cover, just loosen 1/3 of the bolt, and then turn the cover clockwise 10° It can be opened immediately, and the bolts are not lost, and the effect of quickly opening the cover can be achieved. There are two types of explosion-proof grades, ExdIIBT4 and ExdIICT6. The appearance is one-way, two-way, three-way, four-way, corner-way, hanging cover-way, etc.

3. Explosion-proof threading box

Explosion-proof threading box is an explosion-proof accessory used in dangerous places, with an increased safety structure; the shell is made of cast aluminum alloy, using advanced high-temperature one-time die-casting molding process, the surface is smooth, and the appearance is exquisite and beautiful. The shell has good explosion-proof performance, and the explosion-proof mark is directly pressed on it; the joint surface between the product body and the cover is sealed with rubber, which has good sealing performance, and there are eight options for appearance, straight, three-way, four-way, left-handed, right-handed, bottom Back bend, bottom back tee, ingot bend.

4. Explosion-proof isolation sealed box

The shell is made of aluminum alloy die-casting, with high-voltage electrostatic spraying on the surface; it is connected by pipe threads; it has good sealing performance and is suitable for explosive gas environments of IIA, IIB, and IIC; we routinely use y-type, and the specifications are G1/2 "-G4" etc.

5. Explosion-proof flexible pipe

Explosion-proof flexible connecting pipes are suitable for combustible dust environments in areas 20, 21, 22, and IIBIIC-level T1-T6 groups of explosive mixtures. They are used as connections for incoming and outgoing lines of explosion-proof electrical equipment or for connections in places where it is difficult to bend steel pipe wiring. . Explosion-proof flexible pipe structure The two ends of the hose are metal threaded joints, and the pipe body is composed of three forms: metal hose, outer layer of high-quality rubber and reinforced nylon hose sheath, and interlayer steel wire braided network pipe. This product has the advantages of flame resistance, oil resistance, corrosion resistance, water resistance, wear resistance, aging resistance, good flexibility, firm structure, and reliable operation. Generally, it has 500, 700, 1000 lengths. Length and thread size can be specially processed according to user needs. Such as NPT thread, metric thread, etc.

6. Explosion-proof joints

1) Explosion-proof union

Made of high-quality carbon steel or stainless steel, it is suitable for explosive and dangerous environments such as petroleum refining, storage, chemical industry, medicine, military industry and military facilities; multiple specifications and types are available, the thread specification is generally pipe thread, and there are double internal Thread, one inner and one outer thread, double outer thread is optional, the thread type at both ends of the standard product is pipe thread, and it is the same specification.

2) Explosion-proof pipe joints

Explosion-proof pipe joint is an explosion-proof product made of high-quality carbon steel. It is mainly installed in dangerous places.

3) Explosion-proof cable clamping and sealing joint

Widely used in many industries such as shipbuilding manufacturing, power distribution cabinet production plants, rolling stock, bridges, electric power and communications. It is used for clamping and sealing of electrical equipment cables.

It is used to lock or match the cable on the electric control cabinet box and seal it with epoxy glue. It has the advantages of simple structure, low cost, various forms, firm installation, convenient use, and good sealing effect. It can be made of carbon steel, brass, stainless steel and other materials, and the diameter of the cable that can be matched according to different joint forms ranges from 5-57mm.
