Description
Technical field
The utility model relates to explosion-protection equipments, and in particular to the anti-explosion cable introducing device entered for cable.
Background technique
In the petrochemical industry of Chinese national economy pillar industry, production scene 60~80% belongs to explosion risk field
Institute, electrical equipment use antiknock device, and anti-explosion cable introducing device is component of the cable into and out of antiknock device, and cable introduces
The anti-explosion safety of the whether reliable direct relation antiknock device of device.
In recent years, national and each supervision department finds in the safety inspection with antiknock device anti-in explosion hazard place
The cable intake safety problem of quick-fried equipment is especially prominent one of problem, is mainly manifested in multi-cable and sets into and out of explosion-proof
It is standby, cause intake fine and close cannot block, once generating explosion inside antiknock device, flame will be spread out of from intake, be ignited anti-
Explosive gas around quick-fried equipment, leads to safety accident.
Therefore, a kind of novel anti-explosion cable introducing device is developed, antiknock device multi-cable is solved and enters an intake
The problem of have a very important significance.
Utility model content
Technical problem to be solved in the utility model is, in view of the deficiencies of the prior art, provide a kind of multi-cable into
Enter the explosion-proof introducing device an of intake, convenient for installing and using in explosion hazard area.
In order to achieve the above objectives, the utility model adopts the following technical solution:
The utility model is a kind of novel anti-explosion cable introducing device, including shell, into cable port and out cable port, and
Seal Plastic-sheathed Cable inlet wire into the sealing element of cable port and the protection O-ring of dustproof and waterproof sealing, into cable port and go out
Flame proof thread is equipped in cable port, wherein described is 2-5 into cable port, preferably 2-3, cable port is 1 out；It should be into
Cable port is Plastic-sheathed Cable into cable port, armouring jacketed cable into cable port, spare into one of cable port or a variety of, rubber set
Cable is made of into cable mouthful seal ageing-resistant rubber sealing ring, gasket, closeouts and clamp nut, rubber seal internal diameter
It is matched according to outside diameter of cable size, Plastic-sheathed Cable passes through rubber seal, gasket and clamp nut, passes through clamp nut clamping pad
Piece squeezes rubber seal plastic deformation, reaches the fine and close closure between cable, sealing ring and shell, meets explosion-proof sealing ring electricity
The requirement of cable incoming line structure；Armouring jacketed cable is set into the pressure armouring that cable port is equipped with compression armor, the armouring sheath electricity
Cable into cable port and pressure armouring set between cross the explosion-proof solidification clay of filling at line；The sealing element of cable in stock mouth is by ageing-resistant rubber
Sealing ring, gasket, explosion-proof silk plug and closeouts composition.Flame proof thread on flame proof thread (external screw thread) and antiknock device on shell
(internal screw thread) connects and composes the cable entry of antiknock device, guarantees dustproof and waterproof by protection O-ring between the two.
In the above-mentioned novel anti-explosion cable introducing device of the utility model, it is described into cable port be Plastic-sheathed Cable into cable port
With armouring jacketed cable into cable port.
Further preferably, in the above-mentioned novel anti-explosion cable introducing device of the utility model, the shell is equipped with electrical
The ground connections of protection.
The utility model has the advantages and positive effects of:
In the structure design of the explosion-proof introducing device of the utility model, anti-explosion cable introducing device is designed to that goes out a cable
Mouthful, more enter cable intake, can enter rubber sheathed cable and armouring jacketed cable.Plastic-sheathed Cable passes through rubber seal
Circle, gasket and clamp nut squeeze rubber seal plastic deformation by clamp nut compress gasket, reach cable, sealing ring
And the fine and close closure between shell；Armouring jacketed cable presses armouring to set compression armor by armouring jacketed cable, is crossing at line
It fills explosion-proof solidification clay and reaches explosiveproof isolation sealing；The wire leading method of two ways solves multi-cable and enters an intake
Problem；Meanwhile external earth connection is set on shell, grounding body is connected to by the external ground wire in scene, prevents equipment live from making
It gets an electric shock at personnel.
Detailed description of the invention
Fig. 1 is the transverse sectional view of the utility model anti-explosion cable introducing device.
1 is shell in Fig. 1, and 2 be rubber seal, and 3 be closeouts, and 4 be gasket, and 5 be protection O-ring, and 6 be compression spiral shell
Mother, 7 are explosion-proof silk plug, and 8 set for pressure armouring, and 9 be ground connections.
Specific embodiment
It is practical new to this with reference to the accompanying drawing for the invention, features and effects for being better understood on the utility model
The technology of type is further described.
As shown in Figure 1, a kind of above-mentioned novel anti-explosion cable introducing device of the utility model, including shell 1, rubber seal
2, closeouts 3, gasket 4 protects O-ring 5, clamp nut 6, and explosion-proof silk plug 7 presses armouring to set 8, ground connections 9；Anti-explosion cable
Introducing device is designed to that goes out a cable port, it is multiple for introduce cable into cable port, rubber sheath electricity can not only be installed
Cable, and armouring jacketed cable can also be installed, solve the problems, such as that the multi-cable of different types enters a cable entry
In the structure design of the utility model, the quantity of the incoming line is 2-5, as shown in Figure 1, being into cable port
3, wherein 1 into cable port be used for Plastic-sheathed Cable inlet wire, Plastic-sheathed Cable into cable port mainly by rubber seal 2, gasket 4,
Closeouts 3 and clamp nut 6 form, and rubber seal 2 is ageing-resistant sealing ring, and internal diameter of the seal ring is according to outside diameter of cable size
Apolegamy, when installation cable is that closeouts 3 are removed, Plastic-sheathed Cable passes through rubber seal 2, gasket 4 and clamp nut 6, passes through pressure
Tight 6 compress gasket 4 of nut squeezes rubber seal 2 and is plastically deformed, and reaches the fine and close envelope between cable, sealing ring 2 and shell 1
It is stifled, meet explosion-proof sealing ring long cable section of ingoing line structural requirement；Another 1 therein is used for armouring jacketed cable inlet wire, armour into cable port
Dress jacketed cable sets 8 into the pressure armouring that cable port is equipped with compression armor, and armouring jacketed cable is by pressing armouring to set 8 compression armourings
After layer, sets in armouring jacketed cable into cable port and pressure armouring and cross the explosion-proof solidification clay of filling at line between 8 and reach explosiveproof isolation
Sealing, meets explosion-proof encapsulation string-passing structure requirement.
In the structure design of the utility model, if the cable into cable port not into cable when, using explosion-proof 7 envelope of silk plug
Stifled, screw thread is flame proof thread between shell 1 and explosion-proof silk plug 7, and screw tip has a protection O-shaped rubber ring 5, structure meet it is explosion-proof,
Dust and water protection requirement.
The device of the utility model is installed and is used, and only replacement does not meet the cable of the antiknock device of standard criterion requirement
