Abstract
The utility model relates to an air valve pressure regulating tower structure. The utility model aims at providing a construction convenience, simple structure's air valve pressure regulating tower structure improves water delivery system water hammer protecting effect and practices thrift the construction investment. The utility model provides a: an air valve pressure regulating tower structure, has long distance conduit, its characterized in that: be equipped with top seal's pressure regulating tower in conduit's local bump position, the air valve is equipped with in pressure regulating top of the tower portion, and pressure regulating tower bottom meets with conduit through the connecting pipe. The utility model is suitable for a reduce vacuum and extreme water hammer pressure in the pipeline in the long distance pump station water lift engineering.
Description
Technical field
This utility model is related to Hydraulic and Hydro-Power Engineering, and more particularly, to a kind of air cock pressure regulation tower structure is it is adaptable to distance
Reduce vacuum and the extreme water hammer pressure in pipeline in pumping plant water lift engineering.
Background technology
Air cock is widely used in waterline, is primarily due to air cock and has cheap, installation
A large amount of drainings, pipeline micro aerofluxuss when normally running when changing convenience, pipeline water-filling, and during accident, a large amount of air inlets prevent from bearing
Pressure, slow aerofluxuss formation air cushion prevent the feature of excessive water hammer pressure；But air cock equally has due to air inlet, supply water weight
Time-consuming longer shortcoming during new recovery.
Air cock is generally arranged at pipeline raised points position, and in order to give full play to its function, (overpressure is reduced to air
Just work during pressure).If but when water delivery line is relatively gentle or the indivedual raised points of pipeline are high, its protecting water hammer effect will
Limited by larger；In order to meet the normal dual requirementses running with protecting water hammer of pipeline, satisfaction need to arranged on pipeline just
When often running, the air cock of intake and exhaust functions, there is provision of the Other Engineering measure dedicated for protecting water hammer simultaneously.
In addition, being provided with surge tower in built engineering, if desired improve water supply capacity, then may lead to surge tower overflow and
Protecting water hammer effect cannot meet the situation of requirement, needs surge tower is increased or discarded surge tower in a conventional manner, choosing
Take other protecting water hammer means.
Content of the invention
The technical problems to be solved in the utility model is：For above-mentioned problem, provide a kind of easy construction, structure
Simple air cock pressure regulation tower structure, improves water-carriage system protecting water hammer effect and saves construction investment.
This utility model be employed technical scheme comprise that：A kind of air cock pressure regulation tower structure, has the water-supply-pipe of distance
Road it is characterised in that：It is provided with the surge tower of top sealing in the local bump location of aqueduct, pressure regulation top of tower is equipped with air
Valve, pressure regulation tower bottom is connected with aqueduct through connecting tube.
Installation and repairing valve in the middle part of described connecting tube.
The beneficial effects of the utility model are：This utility model is provided with pressure regulation in the local bump location of aqueduct
Tower, this surge tower is equivalent to artificial setting salient point in the duct, to improve the protecting water hammer effect of air cock, simultaneously because adjusting
The presence of pressure tower avoids the situation that the air occurring under ordinary accident operating mode enters pipeline, improves water supply resume speed；That is,
Effectively solve route gentle when or setting surge tower enlarging water pump water lift engineering protecting water hammer effect, reduce length
Vacuum in pumping plant water lift engineering pipeline and extreme water hammer pressure, reduce construction investment.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, the present embodiment is applied to distance pumping plant water lift engineering, in particular for water line relatively gentle or
It is provided with the extension project of surge tower.This example is a kind of vacuum that can reduce in distance pumping plant water lift engineering pipeline and
The air cock pressure regulation tower structure of big water hammer pressure, this structure has the aqueduct 1 of distance, in the Local Convex of aqueduct 1
Point position is provided with surge tower 4, and is connected with aqueduct 1 by being located at surge tower 4 bottom connecting tube 2, in the middle part of connecting tube 2
Equipped with maintenance valve 3 on appropriate location, it is easy to maintenance or the maintenance of surge tower 4.Air cock 5 is installed at described surge tower 4 top
And so that pressure regulation top of tower is sealed, this surge tower is equivalent to artificial setting salient point in the duct, is prevented with the water hammer improving air cock 5
Shield effect.Because set location is high, has during accident and can play protecting water hammer effect as early as possible, strengthen pipe protection effect.
The operation principle of the present embodiment：When actual water delivery line is shallower, the protecting water hammer for improving air cock 5 is made
With arranging artificial salient point, i.e. the surge tower 4 of top sealing；Air cock 5 is set at surge tower 4 top, forms air cock surge tower
Structure.When waterline water-filling, maintenance emptying, gas passes in and out still from air cock 5, and when normally running, surge tower 4 is full of
Water body, air cock 5 is closed.When normal termination of pumping or pumping accident, because air cock 5 position is high, surge tower 5 top
Hydraulic pressure when dropping to subatmospheric, air cock 5 starts a large amount of air inlets, and (ordinary accident operating mode is preferably able to ensure that gas exists
In surge tower, to improve water supply resume speed), prevent from when manifold pressure is too low, exceeding the negative pressure limit that pipeline bears；Work as tune
After pressure chamber 4 is gone up with pipeline junction pressure, water level lifting in surge-chamber 4, gas compression, by air cock slow discharge in case
Excessive water hammer pressure only occurs.
If the surge tower 4 in this utility model is changed to a vertical short tube, air cock 5 is set at short tube top and also can play
The more preferable protecting water hammer effect than the air cock of general setting.
