Abstract
The utility model relates to a pressure plugging device used during maintenance of urban gas building pipes, in particular to a micro-pressure scavenging port plugging device. The scavenging port plugging device comprises a seal box, wherein the seal box is connected with a connector of a pipeline to be maintained, holes are formed in side walls of the seal box, latex gloves are arranged on the holes and are connected with the seal box in a sealing mode, an air inflation bag is arranged in the seal box, one end of an air guide pipe stretches into the seal box to be connected with the air inflation bag, the other end of the air guide pipe is connected with an air guide hose, the other end of the air guide hose is connected with a plugging air bag, and a guide rod is also arranged in the seal box. The scavenging port plugging device has the advantages that all processes are carried out in a controllable state, and therefore the pressure plugging device has high operation safety; the pressure plugging device further has high pertinence; only faulted gas transmission pipes are plugged in the operation process, and other units are not affected; two-inch pipes are plugged through sextant ports.
Description
Technical field
Sealer under pressure when the utility model relates to a kind of gas and enters the maintenance of building pipeline, relates in particular to a kind of minute-pressure blow valve port plugging device with pressure of gas.
Background technique
The mode of taking while entering now the maintenance of corridor natural gas line has two kinds: 1, entire building is died and overhauled; 2, directly maintenance under gas leakage state.First kind of way can have influence on entire building the inside user's the gas of using, and affects resident's life, easily causes bad impact; There are a lot of potential safety hazards in the second, easily accidents caused generation.
Summary of the invention
Blow valve port blocking device with pressure when the purpose of this utility model is just to provide the maintenance of a kind of simple in structure, easy to operate natural gas line, need stop the supple of gas or steam or brave dangers when it has solved natural gas line maintenance in the past and carry out the problem of upkeep operation.
The technological scheme that the utility model provides is:
Blow valve port plugging device, comprise sealed case, sealed case is connected with needing the pipe joint of maintenance, and sealed case sidewall arranges porose, and place, hole is provided with emgloves, emgloves and sealed case are tightly connected, in sealed case, have gas-filling bag, air pipe one end is stretched in sealed case and is connected with gas-filling bag, and the air pipe the other end is connected with soft air-guide pipe, the other end of soft air-guide pipe connects shutoff air bag, is also placed with guide rod in sealed case.
Concrete, in described sealed case, be placed with working tool.
Concrete, described sealed case is connected with needing the reducer union of six minutes jointings of pipeline of maintenance.
Concrete, on described air pipe, cover has choke ring.
The utility model directly needs six minutes jointings of service conduits to carry out shutoff from blow valve port, shutoff air bag is entered in gas transmission line, by gas-filling bag to the voltage supply of shutoff air bag, thereby make shutoff air bag expansion shutoff gas transmission line, stop main line to be continuously into corridor branch line air feed, to facilitate the gas pipeline maintenance of whole unit.Use the utility model without entire building, stop the supple of gas or steam or just can carry out maintenance operation under leak condition when gas enters the maintenance of corridor branch line.The beneficial effects of the utility model have: 1, all processes all under controllable state Job Operations safe; 2, with strong points; 3, the in-problem gas transmission branch line of shutoff during operation, does not affect other unit.

Embodiment
Be illustrated in figure 1 blow valve port plugging device, comprise sealed case.Sealed case sidewall arranges porose, and place, hole is provided with emgloves, and emgloves and sealed case are tightly connected, and have gas-filling bag in sealed case.Air pipe one end is stretched in sealed case and is connected with gas-filling bag, and the air pipe the other end is connected with soft air-guide pipe, and on air pipe, cover has choke ring.The other end of soft air-guide pipe connects shutoff air bag, is also placed with the instruments such as spanner that guide rod and operation need to be used, screw-driver in sealed case.
While using the utility model, sealed case is fixed.Blow valve port place needs six minutes jointings of service conduits to be provided with two cun of reducer unions that become six minutes, and reducer union has plug to stop up.Sealed case is connected with the outer wall of reducer union, then by people's handling spanner, installation and the plug in reducer union is unloaded, plug is placed in sealed case.With guide rod, through air pipe, shutoff air bag is pushed in the pipeline that needs shutoff afterwards, the pipeline that makes choke ring be positioned at six minutes jointings of service conduits will be managed inside and outside space sealing and be separated.After utilize guide rod that shutoff gasbag plug is released guide rod to design attitude again, connect afterwards air pipe and gas-filling bag and push gas-filling bag to shutoff airbag aeration, make shutoff air bag shutoff gas transmission line, stop to corridor user gas transmission, carry out maintenance operation.Gas after operation completes in discharge shutoff air bag is also taken out, and plug is installed, and removes sealed case.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characteristics is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
