Technical field
The utility model relates to, drainage pipe constructing device, especially relates to a kind of pipeline fast plugging device.
Background technique
At present, various types of pipeline all uses conventional welding operation technique basically when upkeep operation, on-line maintenance, replacing valve, installation offtake.Close not dead situation owing to by the maintenance pipeline upper level valve is often taken place, the swelling that causes having certain pressure in the pipeline goes out, if welding, electric welding field not only produce problems of welded quality by force, also can cause a hidden trouble to the operating personnel is safe (get an electric shock, scald, drown etc.).If run into this situation, can only enlarge the scope of cutting off the water, upper level to be closed dead valve replacing or stops production install blind plate additional, this operating process is not only loaded down with trivial details, and consuming time very long, has a strong impact on the upkeep operation process.As follows through the existing plugging technology of retrieval and inquiry data: pipeline water flow stop CN200920000667.6 and novel pipeline plugging pig CN200820162274.0 are mainly used in pressure testings such as domestic water pipeline, fire-fighting water pipeline, drainage pipeline, sewage conduct, block current when closing water experiment, maintenance or dredging operation, realize interim blocking pipe; Also can be used for coal gas, use such as shutoff airflow line when heat distribution pipeline is speedily carried out rescue work operation.This principle mainly is to utilize ball inflation principle, inflating air to the caulking gum body makes its distending in pipeline, produce frictional force sealing obstruction operation pipeline after relying on the caulking gum volumetric expansion, but above-mentioned technology has insurmountable technical problem, namely have under the situation that the swelling of certain pressure goes out at the operation pipeline, if it is then very difficult that above-mentioned type of tamper evidence is filled in the band pressure piping by force, rubber body is stopped up also not sufficient gas spreading situation and is just gone out by water often, band presses the obstruction effect undesirable, and must ceaselessly rely on professional inflatable tool to charge into air in these two kinds of technology operations, this process length consuming time influences the operation process of speedily carrying out rescue work.
The model utility content
For overcoming above-mentioned defective, the purpose of this utility model is, a kind of pipeline fast plugging device is provided, and described pipeline fast plugging device can carry out shutoff to domestic water pipeline, fire-fighting water pipeline, drainage pipeline, sewage conduct, gas pipe line and the heat distribution pipeline operation airflow line of speedily carrying out rescue work.Special solution must not thoroughly cut off the water, when stopping the supple of gas or steam, the shutoff problem that have certain flow in the operation pipeline, still has certain overbottom pressure to gush out.
The technical solution of the utility model is as follows:
This pipeline fast plugging device comprises annular rubber pocket, pipe plug toroidal frame and closes water valve, it is characterized in that:
Described pipeline fast plugging device also has one-way valve and Air filling and discharging valves, an end that closes water valve links to each other with waste pipe, the described the other end that closes water valve links to each other with described pipe plug toroidal frame, the both sides of pipe plug toroidal frame link to each other with annular rubber pocket respectively, annular rubber pocket is fixing with pipe plug toroidal frame symmetry respectively up and down, the pipe plug toroidal frame closes water valve relatively for filling in direction, water (flow) direction arranges one-way valve with direction one side of filling in of filling in the opposite described annular rubber pocket of direction level, and water (flow) direction one side of annular rubber pocket connects Air filling and discharging valves.
According to a kind of pipeline fast plugging device of the present utility model, it is characterized in that: described pipe plug toroidal frame is hollow circular cylinder.
According to a kind of pipeline fast plugging device of the present utility model, it is characterized in that: described annular rubber pocket is drum type, sphere, each position rounding off.
According to a kind of pipeline fast plugging device of the present utility model, it is characterized in that: described one-way valve is the spring Pilot operated check valve.
According to a kind of pipeline fast plugging device of the present utility model, it is characterized in that: described angle of swing of closing the Joystick of water valve is the right angle.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
The utility model owing to utilize ducted current to be full of air bag inside voluntarily earlier, need not a large amount of labor intensive air bag is inflated on volume when the shutoff operation, shortened the obstruction activity duration, and has pressure release, decompression to fill in function.Can not only carry out quick blocking and plugging effect is good to pipeline, and the simple easy operating of principle, be particularly suitable for pipe pressurized power repairing shutoff operation in emergency circumstances.

Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Fig. 1～3, pipeline fast plugging device of the present utility model comprises annular rubber pocket 1, one-way valve 2, Air filling and discharging valves 3, pipe plug toroidal frame 4 and closes water valve 5, an end that closes water valve 5 links to each other with waste pipe, the other end that closes water valve 5 links to each other with pipe plug toroidal frame 4, the both sides of pipe plug toroidal frame 4 link to each other with annular rubber pocket 1 respectively, annular rubber pocket 1 is that axisymmetric is fixed with pipe plug toroidal frame 4 respectively up and down, direction one side of filling in of annular rubber pocket 1 is equipped with one-way valve 2, and water (flow) direction one side of annular rubber pocket 1 is connected with Air filling and discharging valves 3.
See also shown in Fig. 4 ~ 5, the working principle of pipeline fast plugging device of the present utility model is as follows: at upkeep operation, more in the water-changing tube operation process, if the upper level valve of pipeline is not closed fully, just having a large amount of water band pressures in the pipeline gushes out, cause the welding operation to implement, to close water valve 5 and be in open mode this moment, and under passive state, integral body is filled in the pipeline that needs shutoff in the annular rubber pocket 1.In filling in process because one-way valve 2 is in the obstruction front end, and meets water and enter pipeline, the part water of gushing out can be entered in the annular inflatable capsule 1 by one-way valve 2 in the pipeline, all the other than big water quantity then by flowing out through closing water valve 5 external water pipe pressure releases in the middle of the pipe plug toroidal frame 4.When the pipe interior branch water of gushing out is entered by one-way valve 2 in the annular rubber pocket 1 and with annular rubber pocket 1 spreading and is close to inner-walls of duct, when internal pressure equals in the pipeline water burst pressure in the annular rubber pocket 1, one-way valve 2 resets and closes automatically, charged into little air this moment by Air filling and discharging valves 3, annular rubber pocket 1 internal pressure is further increased, make the capsule ancient piece of jade, round, flat and with a hole in its centre of annular rubber pocket 1 be close to inner-walls of duct generation frictional force.After confirming that annular rubber cyst wall and inner-walls of duct are fastening, to close and close water valve 5, shutoff finishes.Just can conveniently carry out the welding operation this moment, finishes the maintenance task.
