Description
Technical Field
The utility model relates to a pressure water pipe, especially a negative pressure compensation arrangement for pressure water pipe.
Background
At present, a pressure flow water conveying main line is usually provided with a peripheral pressure regulating well or an air compensating valve to reduce the damage of negative pressure working conditions to a pipeline structure, so that the occupied area and the construction cost are increased, and the action of the peripheral pressure regulating well or the air compensating valve is not ideal because the position of negative pressure generation is difficult to determine for a long-distance pressure flow water conveying main line pipeline with large size change.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a negative pressure compensation arrangement for pressure water pipeline is provided, when the negative pressure operating mode takes place for long distance pressure flow water transportation main line pipeline, in time clear up the negative pressure and protect pipeline safety.
In order to solve the technical problem, the utility model discloses a technical scheme is: the negative pressure compensation device comprises a negative pressure pipe with a pipe wall provided with a plurality of through holes, a negative pressure compensation bag and an isolation pipe hoop, wherein the negative pressure compensation bag is sleeved outside the negative pressure pipe, the isolation pipe hoop fastens the negative pressure compensation bag on the negative pressure pipe in a segmented sealing manner, one end of the negative pressure compensation device is sealed, and the other end of the negative pressure compensation device is paved outside the pressure flow water delivery main pipeline through the negative pressure pipe and is communicated with an external water source or air.
The through holes on the negative pressure pipe are uniformly arranged along the length direction of the negative pressure pipe.
The through holes on the negative pressure pipe are arranged in a quincunx shape along the length direction of the negative pressure pipe.
The negative pressure compensation bag is made of rubber.
The utility model has the advantages that: the compensation gas or liquid does not pollute the water supply, and the negative pressure randomly generated by the long-distance pressure flow water transmission main pipeline can be dissipated, so that the water transmission safety is guaranteed.
Drawings
Fig. 1 is a schematic view of the negative pressure compensating device for a pressure water pipe of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model discloses a negative pressure compensation arrangement for pressure conduit, negative pressure compensation arrangement lays in pressure flow water delivery main line pipeline 1, negative pressure compensation arrangement includes that the pipe wall has negative pressure pipe 2 of a plurality of perforating holes, negative pressure compensation bag 3 and isolation ferrule 4, negative pressure compensation bag 3 cover is in the negative pressure pipe 2 outside, isolation ferrule 4 fastens negative pressure compensation bag 3 segment seal on negative pressure pipe 2, negative pressure compensation arrangement is one end sealed, another is laid outside pressure flow water delivery main line pipeline 1 through negative pressure pipe 2, switch-on external water source or air, can dissipate the negative pressure that produces at random in the pipeline under pressure at any time, ensure pipeline under pressure's structural safety.
Preferably, the through holes of the negative pressure tube 2 are uniformly arranged along the longitudinal direction of the negative pressure tube.
Preferably, the through holes of the negative pressure tube 2 are arranged in a quincunx shape along the longitudinal direction of the negative pressure tube.
The negative pressure compensation bag 3 is made of rubber.
When the pressure flow water transmission main pipeline 1 is in a negative pressure working condition, external water source or air enters the negative pressure compensation bag 3 generating a negative pressure area through the negative pressure pipe 2 to dissipate negative pressure borne by the pressure flow water transmission main pipeline 1 in the negative pressure area; when the pressure flow water transmission main pipeline 1 recovers the positive pressure working condition, the water or air in the negative pressure compensation bag 3 is discharged in a backflow mode.
The negative pressure pipe 2 can be made of steel, has high strength, and can adjust the number of holes and the hole diameter of the holes as required.
The negative pressure compensation bag 3 can be made of rubber, has good water tightness and air tightness and certain elasticity, and can ensure the structural safety of the pressure flow water delivery main pipeline 1 in a self-explosion mode when the negative pressure of any section of pipeline is too high.
Preferably, the isolation pipe hoops 4 can be replaced by steel wire bands, and specific installation positions and number can be determined according to needs.
The utility model discloses need not peripheral hardware regulator or building, compensating gas or liquid can not pollute the water supply, can dissipate the negative pressure that long distance pressure flow water delivery main line pipeline produced at random, guarantee water delivery safety.
The above-mentioned embodiments are only used for illustrating the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, the scope of the present invention should not be limited by the embodiment, that is, all equivalent changes or modifications made by the spirit of the present invention should still fall within the scope of the present invention.
