Abstract
The utility model belongs to the technical field of explosion-proof chamber construction, and relates to a cable explosion-proof pipe installation structure in an explosion-proof chamber. A galvanized seamless steel pipe is sleeved on a cable in the explosion-proof chamber, wherein the galvanized seamless steel pipe is connected with explosion-proof equipment in the explosion-proof chamber through a threaded connecting piece. A sleeve is additionally arranged at the position where the galvanized steel pipe penetrates through the explosion-proof chamber. One end, which is outside the explosion-proof chamber, of a cable pipe is provided with a stuffing box which is sealed by sealing filler. When a plurality of galvanized seamless steel pipes are used in pipe threading, the galvanized seamless steel pipes are mutually connected by adopting cutting sleeve type straight-through pipe joints. The cable explosion-proof pipe installation structure provided by the utility model optimizes construction of cable pipe threading in the explosion-proof chamber, is simple in construction and convenient to disassemble, reduces the construction difficulty, saves the cost, and shortens the construction period.
Description
Technical field
The utility model belongs to explosion-proof technical field of construction, is specifically related to a kind of explosion-proof cable explosion-proof pipe mounting structure.
Background technology
Much depositing the place that explosive substance might occur, must build explosion-proof according to requirement of explosion proof, generally speaking, should avoid at explosion-proof cabling as far as possible.But because a lot of explosion-proof have the requirements such as illumination, ventilation, fire detector, unavoidably want cabling.For avoiding temperature rise and electric spark to cause the danger of explosion-proof blast, need to adopt the method for laying the metal explosion stack to carry out the poling protection to the cable that enters explosion-proof.According to GB3836.14-2000 " explosive gas atmosphere power consumption equipment the 14th part: hazardous area classification " and GB50058-92 " code for design of electric installations within explosion and fire hazard atmospheres " regulation, the frequency and the lasting time that occur according to explosion environment are divided into different zones to the hazardous area, the gas place is divided into Three regions: 0 district, 1 district, 2 districts, the dust place is divided into Three regions: 20 districts, 21 districts, 22 districts.When carrying out the construction of anti-explosion cable pipe poling, the general zinc-plated seamless steel pipe that meets the GB/T8162-1999 standard that adopts is as explosion stack, and the installation immobilization material of explosion stack adopts the serial pipe clamp that meets the CB/T3780-1997 standard.Length according to every explosion stack prepares the threaded articulation of pipe clamp and two or joint sleeve, and articulation and joint sleeve are configured to guarantee that according to the quantity of cable tube elbow, the length of explosion stack it is principle that drawing of cable applied convenient usually.Explosion stack bend the elbow that should not occur more than two and two.In the above-mentioned explosion stack mounting structure, zinc-plated seamless steel pipe directly welds between zinc-plated seamless steel pipe and the zinc-plated seamless steel pipe after bending, and cost is high, long construction period and construction, difficult in maintenance.
The utility model content
Technical problem to be solved in the utility model provides a kind of easy construction, efficient is high, cost is low explosion-proof cable explosion-proof pipe mounting structure.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of explosion-proof cable explosion-proof pipe mounting structure, explosion-proof inner cable worn zinc-plated seamless steel pipe, described zinc-plated seamless steel pipe is threaded connection part with described explosion-proof interior antiknock device and is connected, pass explosion-proof partition place at described zinc-plated seamless steel pipe and add tubing, the end of cable tube outside described explosion-proof joined stuffing box, and described stuffing box seals with airtight and watertight padding.
Preferably, for described explosion-proof cable pipe, when having used many zinc-plated seamless steel pipes when poling, described zinc-plated seamless steel pipe adopts holding sleeve joint of straight-through pipe to connect each other.
The utility model is optimized explosion-proof cable pipe cable laying operation, and construction is simple, and convenient disassembly has not only reduced difficulty of construction and can save cost, shortened construction period, is conducive to safeguard in the future.
Description of drawings
Fig. 1 is explosion-proof cable explosion-proof pipe mounting structure of the utility model embodiment schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
The dangerous material cabin 3 in the explosion-proof cabin of 2500T cargo ship, main explosive is explosive solid particle, explosion hazard is larger.According to GB3836.14-2000 " explosive gas atmosphere power consumption equipment the 14th part: hazardous area classification " and GB50058-92 " code for design of electric installations within explosion and fire hazard atmospheres ", dangerous material cabin 3 is 20 districts.
As shown in Figure 1, the 3 li installation fire-proof motors 4 in dangerous material cabin, explosion-proof cable explosion-proof pipe mounting structure is: cabin inner cable 5 lays by wearing zinc-plated seamless steel pipe 6, zinc-plated seamless steel pipe 6 is threaded connection part 7 with fire-proof motor 4 and is connected, 3 bulkhead places add tubing 8 to zinc-plated seamless steel pipe 6 in the dangerous material cabin, the end of zinc-plated seamless steel pipe 6 outside dangerous material cabin 3 joined stuffing box 9, and stuffing box 9 usefulness airtight and watertight paddings sealing has guaranteed that cable and explosion-proof cabin are fully isolated.Because cable is longer, used altogether 6, three zinc-plated seamless steel pipes 6 of three zinc-plated seamless steel pipes to adopt each other holding sleeve joint of straight-through pipe 10 to connect during poling, both convenient construction guaranteed again isolated.
Explosion-proof cable explosion-proof pipe mounting structure of the utility model embodiment is optimized explosion-proof cable pipe cable laying operation, and construction is simple, and convenient disassembly has not only reduced difficulty of construction and can save cost, shortened construction period, is conducive to safeguard in the future.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
