Description

Armored single-seal explosion-proof cable stuffing box

Technical Field

The utility model relates to a cable packing box technical field especially relates to a single sealed explosion-proof cable packing box of armor.

Background

The explosion-proof stuffing box is made of brass or stainless steel, if the requirement of stainless steel indicates that the explosion-proof stuffing box is made of brass or stainless steel. The cable is sealed with a filler. The protective performance is good. The explosion-proof device has the characteristics of convenience in use and installation, safe and reliable structure, excellent explosion-proof performance and the like.

The existing armored but sealed explosion-proof cable stuffing box has the problems of unreasonable structural design, long whole, fragile joint, easy fracture, deformation and the like in order to improve the protection performance.

Disclosure of Invention

The utility model aims at solving the current explosion-proof stuffing box structural design unreasonable whole length that leads to long, the fragile shortcoming that easily leads to fracture, deformation of junction, and the explosion-proof cable stuffing box that singly seals of armor that proposes.

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

the utility model provides an explosion-proof cable packing box of armor list seal, includes the connector body and with connector body matched with gland nut, the inside of connector body is provided with rubber seal, gland nut's inboard joint has the taper sleeve, and the joint has the centrum between taper sleeve and the rubber seal, be provided with metal packing ring between centrum and the rubber seal.

Preferably, the inner diameters of the rubber sealing ring, the metal gasket and the cone body are the same in size.

Preferably, the thickness of the taper sleeve increases progressively from bottom to top, and the taper sleeve is nested outside the bottom of the vertebral body.

Preferably, the joint end of the joint body is sleeved with a gasket.

Preferably, the surface of the compression nut is provided with threads, and the inner side of the bottom of the joint body is provided with a thread groove corresponding to the threads on the surface of the compression nut.

Preferably, the compression nut and the joint body are made of alloy materials of H62 and SS304 respectively, the metal gasket, the gasket and the taper sleeve are made of H62 brass, and the rubber sealing ring is made of N230 nitrile rubber.

The utility model has the advantages that:

the utility model discloses an armor single-seal explosion-proof cable packing box design structure is reasonable, and the compact structure of gland nut, the joint body, rubber seal, metal packing ring, centrum, the taper sleeve packing ring that cooperate to use when protective properties can ensure, whole length is short and short, and the junction state is stable, is difficult for resulting in fracture and deformation, and the suitability is stronger.

Drawings

Fig. 1 is a schematic structural view of an armored single-sealed explosion-proof cable stuffing box provided by the utility model;

fig. 2 is the utility model provides a sectional structure schematic diagram of single sealed explosion-proof cable stuffing box of armor.

In the figure: the sealing device comprises a gasket 1, a connector body 2, a rubber sealing ring 3, a metal gasket 4, a cone 5, a taper sleeve 6 and a compression nut 7.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, an armored single-seal explosion-proof cable stuffing box comprises a connector body 2 and a compression nut 7 matched with the connector body 2, wherein a rubber seal ring 3 is arranged inside the connector body 2, a taper sleeve 6 is clamped on the inner side of the compression nut 7, a cone 5 is clamped between the taper sleeve 6 and the rubber seal ring 3, and a metal gasket 4 is arranged between the cone 5 and the rubber seal ring 3;
