Abstract
The utility model discloses a kind of cable direct introducing device of flameproof valve electric device, including plinth, flame proof cylinder, transition body, spin-ended pad, sealing ring, locking body and the explosion-proof clay being filled between flame proof cylinder and cable.Superiority：(1) cable is introduced directly into main box by the present apparatus, and without increasing the parts such as extra terminal box, explosion-proof type terminal board, its connection, wiring, installation are simple and convenient, save manpower, and reliability also greatly improves；(2) separate unit product uses the introducing device, greatly reducing Master Cost；(3) small volume, installing space is saved.
Description
(1) technical field：
Flameproof valve electric device field is the utility model is related to, particularly a kind of electricity of flameproof valve electric device
Cable direct introducing device.
(2) background technology：
It is commonly used for being provided with cable entry in the explosion-proof type electric device for valve of explosive gas atmosphere.Press
According to standard GB/T 3836.2-2000《Electric Equipment in Explosive Gas Atmosphere part 2：Flame-proof type " d "》Regulation, cable
There are two kinds of connected modes：First, introduce indirectly, the mode connected with terminal box or plug assembly；Second, it is introduced directly into, with connecing
Enter the connected mode in main shell.Two conditions must be met using the mode of being introduced directly into：1. spark, electricity are not produced during normal operation
Arc or dangerous temperature；2. rated power≤250W of electrical equipment, but electric current is not more than 5A.
In known known technology, the general indirect incorporation way for using terminal box.Its specific practice is：Terminal box is pacified
On flameproof valve electric device main box, explosion-proof type terminal board is installed in inside, and being provided with cable in terminal box draws
Enter and pressed sealing device, connector cover are arranged on the explosion-proof chamber that sealing is formed in terminal box.This indirect introducing device of cable
When on motor rated power≤250W flameproof valve electric device, its structure, volume are excessively huge, are unfavorable for pacifying
Dress, wiring, debugging；Terminal box, connector cover, explosion-proof type terminal board are introduced plus cable and the entirety of pressing device composition
Production cost is higher, and economy is bad.
(3) utility model content：
The purpose of this utility model is to provide a kind of cable direct introducing device of flameproof valve electric device, and it is tied
Structure is simple, reliable and better economy easy to install.
The technical solution of the utility model is：A kind of cable direct introducing device of flameproof valve electric device, it is special
Sign is to include plinth, flame proof cylinder, transition body, spin-ended pad, sealing ring, locking body and is filled between flame proof cylinder and cable
Explosion-proof clay, one end of the plinth are connected on casing by flame proof thread, and the flame proof jacket casing is in plinth, institute
State one end of transition body and the other end of plinth connected by flame proof thread, sealing ring and spin-ended pad are housed inside transition body,
The other end of the locking body and transition body is connected by flame proof thread, and sealing ring and spin-ended pad are housed inside locking body.
The utility model has the advantages and positive effects of：Technical scheme is used because this is new, with prior art phase
Than having the advantages that：(1) cable is introduced directly into main box by the present apparatus, without increasing extra connect
The parts such as line box, explosion-proof type terminal board, its connection, wiring, installation are simple and convenient, save manpower, and reliability also greatly improves；
(2) separate unit product uses the introducing device, greatly reducing Master Cost；(3) small volume, installing space is saved.
(4) illustrate：
Fig. 1 is the structural representation of the utility model cable direct introducing device.
Wherein 1 is plinth；2 be flame proof cylinder；3 be transition body；4 be spin-ended pad；5 be sealing ring；6 be locking body；7 be electricity
Cable；8 be casing；9 be explosion-proof clay.
(5) embodiment：
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Embodiment：A kind of cable direct introducing device of flameproof valve electric device, it is characterised in that including plinth
1st, flame proof cylinder 2, transition body 3, spin-ended pad 4, sealing ring 5, locking body 6 and the explosion-proof clay being filled between flame proof cylinder 2 and cable 8
9, one end of the plinth 1 is connected on casing 7 by flame proof thread, and the flame proof cylinder 2 is sleeved in plinth 1, described
One end of transition body 3 is connected with the other end of plinth 1 by flame proof thread, and the inside of transition body 3 is equipped with sealing ring 5 and spin-ended pad
4, the locking body 6 is connected with the other end of transition body 3 by flame proof thread, and the inside of locking body 6 is equipped with sealing ring 5 and spin-ended pad
4。
In use, cable is successively from locking body 6, spin-ended pad 4, sealing ring 5, transition body 3, sealing ring 5, spin-ended pad 4, flame proof
Casing 8 is introduced in the endoporus of 2 grade parts of cylinder, explosion-proof clay 9 is then filled between flame proof cylinder 2 and cable 7.
Claims (1)
1. a kind of cable direct introducing device of flameproof valve electric device, it is characterised in that including plinth, flame proof cylinder, mistake
Cross body, spin-ended pad, sealing ring, locking body and the explosion-proof clay being filled between flame proof cylinder and cable, one end of the plinth
Be connected to by flame proof thread on casing, the flame proof jacket casing in the plinth, one end of the transition body and plinth
The other end is connected by flame proof thread, and sealing ring and spin-ended pad are housed inside transition body；The locking body and transition body it is another
