To an explosion-proof cable gland structure for preventing gas leakage.
Description
The present invention relates to an explosion-proof cable gland structure for preventing gas leakage, and in particular, a three-layer hermetically sealed structure can prevent the leakage of gas through a power supply and a signal cable of the apparatus and protect the apparatus from accidents such as explosion and fire. To an explosion-proof cable gland structure for preventing gas leakage.
1, a conventional explosion-proof cable gland includes a
In the conventional 'Korean Patent No. 10-0929931', a method of manufacturing a cable gland for an explosion-proof electric wire bundle is proposed in which a heavy metal such as a conventional cast iron is replaced with aluminum and an anodizing treatment is performed on the surface thereof. Such a patent has a problem in that it does not have a great effect in carrying out the waterproof function.
The present invention has been devised to solve the above problems, and it is possible to prevent leakage of gas through a power supply and a signal cable of a device by using a three-layer hermetic structure, and to protect the equipment from an accident such as an explosion or a fire And an object of the present invention is to provide an explosion-proof cable gland structure for preventing gas leakage whose structure is improved.
The present invention for achieving the above object is an explosion-proof cable gland structure for gas leakage shielding,
A top flange connected to the device and formed with a through hole through which a plurality of cables pass,
A hollow reducer, one end of which is coupled to the through-hole and through which the cable passes,
A first packing coupled to the reducer and having a plurality of through holes through which respective cables passing through the reducer are individually passed,
A hollow body having a first coupling portion formed on one side thereof and a second coupling portion formed on the other side thereof,
A hollow second packing coupled to the body,
A ground screw coupled to the body to urge the second packing against the cable,
A third hollow packing threaded on the top surface of the gland,
And a cover coupled to the second coupling portion of the body to receive the third packing therein so that the third packing closely contacts the cable main surface.
Also, the present invention is characterized in that a pair of O-rings are coupled to the top flange, which is connected to the device, concentrically spaced apart from each other by a predetermined distance.
A first washer is interposed between the lower end of the first engaging portion and the first packing, and a second washer is interposed between the lower end of the gland and the second packing.
This design has a triple hermetic structure and has an improved structure to prevent leakage of gas through the power supply and signal cable of the equipment and to protect the equipment from accidents such as explosion and fire.
