Description
Technical field
The present invention relates to pressure water pipe, especially a kind of pressure water pipe with negative pressure compensating bag.
Background technique
Currently, cities and towns high speed development causes water requirement to increase suddenly, original weight force flow water conveying tunnel water supply capacity is insufficient, bright to reduce
Dig, reduce expropriation of land and removal expense, mostly use in wear after pressure water pipe reconstructs former water conveying tunnel, water delivery of pressurizeing is to improve confession
Water.But pressure water pipe run when be difficult to avoid that generation negative pressure, when negative pressure is excessively high, can damage in wear pressurized water transmission
Pipeline seriously threatens water supply security.
Summary of the invention
The technical problem to be solved by the invention is to provide kind with a kind of pressure water pipe with negative pressure compensating bag,
When negative pressure operating condition occurs for pressure water pipe, negative pressure protective conduit safety is cleared up in time.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that: a kind of pressure with negative pressure compensating bag
Aqueduct, it is alongst above spaced apart at the top of pressure water pipe to be provided with through hole, in through hole
It is inserted with overcurrent short tube, the top of overcurrent short tube and the outer wall of pressure water pipe are equal, and the bottom of overcurrent short tube protrudes from pressure
Aqueduct inner wall, overcurrent short tube outer wall and through hole seal, and in pressure water pipe, overcurrent short tube base opening is fixed with bullet
Property negative pressure compensating bag, communicate and pressure water pipe inner seal on the outside of negative pressure compensating bag and pressure water pipe.
The negative pressure compensating bag is curled in overcurrent short tube in non-pressurising.
The negative pressure compensating bag is made of rubber.
The beneficial effects of the present invention are: being not necessarily to peripheral voltage regulation device or building, compensation gas or liquid will not pollute water supply,
Pressure water pipe is worn in can making to dissipate in time negative pressure, ensures water delivery safety.
Detailed description of the invention
Fig. 1 is the pressure water pipe schematic diagram with negative pressure compensating bag of the invention.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the pressure water pipe with negative pressure compensating bag of the invention, on 2 top edge of pressure water pipe
It is spaced apart on length direction be provided with through hole, overcurrent short tube 4, the top of overcurrent short tube 4 are inserted in through hole
Equal with the outer wall of pressure water pipe 2, the bottom of overcurrent short tube 4 protrudes from 2 inner wall of pressure water pipe, outside overcurrent short tube 4
Wall and through hole seal, and in pressure water pipe 2,4 base opening of overcurrent short tube is fixed with elastic negative pressure compensation bag 3, and negative pressure is mended
It repays and is communicated and 2 inner seal of pressure water pipe on the outside of bag 4 and pressure water pipe 2.
The negative pressure compensating bag 3 is curled in overcurrent short tube 4 in non-pressurising.
The negative pressure compensating bag 3 is made of rubber.
The present invention wears pressurized water transmission when interior for wearing transformation in old pipeline with the pressure water pipe of negative pressure compensating bag
When pipeline 2 is in negative pressure operating condition, former aqueduct 1 and the interior water or air worn in 2 gap of pressure water pipe, through overcurrent short tube
4 enter negative pressure compensating bag 3, wear the negative pressure that pressure water pipe 2 is born in dissipation；When interior pressure water pipe 2 of wearing restores just
When pressing operating condition, water or air return in negative pressure compensating bag 3 are worn in 2 gap of pressure water pipe to former aqueduct 1 with interior.
Steel production can be used in the overcurrent short tube 4, not only intensity height but also linear expansion coefficient and cast iron or concrete
It is close.
It is described to cross negative pressure compensating bag 3, rubber production can be used, not only there is preferable watertightness and air-tightness, also have
Certain elasticity, when pipe negative pressure is excessively high, negative pressure compensating bag 3 can wear pressure water pipe 2 by way of self-destruction, in protection
Structure safety.
It is preferred that pipe collar can be added outside negative pressure compensating bag 3, to ensure that it is securely set with 4 sealing of overcurrent short tube.
Using the interior former water conveying tunnel for wearing pressure water pipe reconstruction, the position needed inside pressure water pipe is worn inside
It sets, suitable negative pressure compensating bag is installed, when pipeline is in negative pressure operating condition, former aqueduct wears pressure water pipe gap with interior
In water or air the negative pressure that pressure water pipe is born is worn in dissipation into negative pressure compensating bag.The present invention is not necessarily to peripheral hardware tune
Pressure device or building, compensation gas or liquid will not pollute water supply, can make in wear pressure water pipe and dissipate in time negative pressure, work as pipe
When road negative pressure is excessively high, negative pressure compensating bag can ensure waterline structure safety by self-destruction mode.
Embodiment described above is merely to illustrate technical idea and feature of the invention, in the art its object is to make
Technical staff it will be appreciated that the contents of the present invention and implement accordingly, patent model of the invention only cannot be limited with the present embodiment
It encloses, i.e., same changes or modifications made by all disclosed spirit are still fallen in the scope of the patents of the invention.
