Cable comes out from rack room in normal situation passes through after gantry is laid to scene again through zinc-plated penetration pipe, explosion-proof around property pipe and Glan
Head access electric meter terminal box.Gantry and galvanized pipe cannot achieve explosion-proof and waterproof want because of factors such as in-site installation arrangements
It asks, because of the factors such as weather and scene leakage, the media such as steam can enter explosion-proof flexible pipe along gantry, galvanized pipe, only pass through lattice
Blue head is high to in-site installation requirement to realize waterproof anti-explosion function, but can often destroy in installation, maintenance, maintenance and disassembly
Its waterproof anti-explosion function.
Therefore, it is necessary to design a kind of explosion-proof flexible pipe of automatic drain to solve the above problems.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of explosion-proof flexible pipes of automatic drain, can be realized
There is liquid to arrange in flexible pipe, the function of aneroid sealing.
The utility model is in order to solve the above technical problems, used technical solution is: a kind of explosion-proof flexibility of automatic drain
Pipe, including the flexible pipe that one end is connected with live electric meter terminal box, the flexible pipe other end is connected with penetration pipe, threads
Pipe is connected with cable testing bridge, drain pipe is additionally provided on flexible pipe, drain pipe upper and lower ends are equipped with sealing ring, in drain pipe
Equipped with sealed ball float.
Preferably, drain pipe is set to flexible pipe lowest part.
Preferably, the diameter of sealed ball float is less than the internal diameter of drain pipe, and is greater than the internal diameter of sealing ring.
Preferably, the density of sealed ball float is less than the density of water, and is greater than the density of air.
Preferably, it is connected by gland head between flexible pipe and live electric meter terminal box, penetration pipe.
Preferably, cover board is equipped on cable testing bridge.
The utility model has the beneficial effects that the utility model can not only realize in flexible pipe there is liquid to arrange, aneroid sealing,
And structure is simple, and it is low in cost, it is easy to accomplish and promote.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the explosion-proof flexible pipe of automatic drain；
Fig. 2 is a kind of structural schematic diagram of drain pipe；
In figure, flexible pipe 1, penetration pipe 2, cable testing bridge 3, drain pipe 4, sealing ring 5, sealed ball float 6, gland head 7, cover board

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As depicted in figs. 1 and 2, the explosion-proof flexible pipe of a kind of automatic drain, including one end and live electric meter terminal box phase
Flexible pipe 1 even, 1 other end of flexible pipe are connected with penetration pipe 2, and penetration pipe 2 is connected with cable testing bridge 3, on flexible pipe 1
It is additionally provided with drain pipe 4,4 upper and lower ends of drain pipe are equipped with sealing ring 5, and sealed ball float 6 is equipped in drain pipe 4.
Preferably, drain pipe 4 is set to 1 lowest part of flexible pipe, and such setting is flowed out convenient for the water in flexible pipe 1, and energy
Enough avoid ponding in flexible pipe 1.
Preferably, the diameter of sealed ball float 6 is less than the internal diameter of drain pipe 4, and is greater than the internal diameter of sealing ring 5.It is such to set
It sets and sealed ball float 6 is moved in drain pipe 4, and without departing from drain pipe 4.
Preferably, the density of sealed ball float 6 is less than the density of water, and it is greater than the density of air.Such setting realizes
When anhydrous in drain pipe 4, sealed ball float 6 reaches sealing effect with the mutual cooperation of the sealing ring 5 of lower end under the effect of gravity；Drain
When having ponding in pipe 4, sealed ball float 6 floats under the action of buoyancy, so that ponding is discharged.
Preferably, it is connected by built-in gland head 7 between flexible pipe 1 and live electric meter terminal box, penetration pipe 2,
Gland head 7 uses internal screw thread, and live electric meter terminal box connector, penetration pipe 2 are all made of external screw thread, gland head 7 and scene
Electric meter terminal box connector, penetration pipe 2 are mutually threadedly engaged connected.Such setting realizes waterproof to a certain extent
Explosion prevention function.
Preferably, cover board 8 is equipped on cable testing bridge 3, cover board 8 plays the role of water proof and dust proof.
Flexible pipe 1 specifically weaves flexible pipe using the external stainless steel of built-in rubber, and penetration pipe 2 specifically uses zinc-plated threading
Pipe, drain pipe 4 specifically use 304SS material, and sealing ring 5 specifically uses rubber material, and sealed ball float 6 specifically uses 304SS material
Matter, gland head 7 specifically use stainless steel material.
The present embodiment working principle is as follows: cable comes out from rack room or switchgear house, is sent by cable testing bridge 3 existing to device
, the cable in cable testing bridge 3 passes through 8 water proof and dust proof of cover board.Cable testing bridge 3 is connected with penetration pipe 2, and cable is using gland head
7 are connected with flexible pipe 1, finally access live electric meter terminal box by gland head 7.
4 top of drain pipe is connected with flexible pipe 1, penetrates into flexibility because of weather, environment and by cable testing bridge 3 for venting
The liquid mediums such as the steam in pipe 1.When the setting of 4 upper end sealing ring 5 of drain pipe ensure that ponding is excessive, sealed ball float 6 not by
It washes away.
It, can be by gravity drainage into drain pipe 4, when product in drain pipe 4 after steam or other liquid enter flexible pipe 1
When water buoyancy is greater than gravity suffered by sealed ball float 6, sealed ball float 6 floats, ponding discharge；When ponding buoyancy is less than sealed ball float 6
When suffered gravity, sealed ball float 6 is fallen, and is connected with the sealing ring 5 of 4 lower end of drain pipe, realizes sealed explosion-proof.
The utility model, which can not only be realized in flexible pipe, has liquid to arrange, aneroid sealing, and structure is simple, at low cost
It is honest and clean, it is easy to accomplish and promote.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the features in the embodiments and the embodiments of the present application in the absence of conflict, can mutual any combination.This is practical new
