Description

A line explosion-proof device

technical field

The utility model relates to a circuit explosion-proof device.

Background technique

In daily production, due to short circuit in some lines or overload of electrical appliances, wires and lines are prone to fire and explosion. Existing wires and circuits are all exposed or set up plastic wire boxes or plastic pipes outside the wires. These plastic wire boxes or plastic pipes are easy to be ignited in the event of a circuit accident, thereby causing a fire in the factory and causing damage to the factory. The production and workers' lives and properties bring hidden dangers.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a line explosion-proof device with simple structure, which can limitly prevent the wire line from igniting other items and causing explosion in the event of an accident.

In order to achieve the above object, the utility model adopts the following scheme:

A line explosion-proof device, characterized in that: an explosion-proof tube coated outside the wire circuit, the explosion-proof tube includes a steel inner tube, and an insulating outer tube is provided outside the inner tube. There is an explosion-proof splitter on it.

A line explosion-proof device as described above is characterized in that the explosion-proof splitter includes an explosion-proof three-way seat, and the explosion-proof pipe is fixedly connected to the two connection ports of the explosion-proof three-way seat. A branching tee joint is connected to the outlet of the explosion-proof three-way seat, and a two-way branching seat is connected to the three-way joint, and an outlet is provided on the two-way branching seat.

A line explosion-proof device as described above is characterized in that the insulating outer pipe is a PVC pipe.

In summary, the utility model has the beneficial effects relative to the prior art as follows:

The explosion-proof device in the utility model includes an explosion-proof tube, and the explosion-proof tube includes a steel inner tube and an insulating outer tube. The wires are arranged in the steel inner tube, which effectively prevents explosion or ignition of other items when the circuit is short-circuited. The inner tube is sleeved with an insulating outer tube to effectively prevent accidents caused by electrical leakage.
