A kind of device for long range water supplying pump system protecting water hammer, there is local high spot in aqueduct, the device of protecting water hammer is connected by service valve on the local high spot, the device of the protecting water hammer includes compressed air cylinder, pressure-reducing valve, air valve, gas pipeline, magnetic valve, the device of the protecting water hammer is set and the tank connected venting channels of compressed air, venting channels are pressure-reducing valve, gas pipeline, magnetic valve A and are linked in sequence, and pass through magnetic valve B connection air valves.The utility model is in Calculations of Hydraulic Transient, injecting compressed air, timely and effectively suppression water hammer harm into pipeline when pressure is less than decompression valve outlet setting pressure in aqueduct, and compared with surge tower and air tank, the installation cost is low；Compared with air valve, the minimum pressure of device installation site is improved, protecting water hammer effect is good；Long range water supplying pump system water hammer is protected in gas injection, it is ensured that rate is high, more safe and efficient.
Description
Technical field
The utility model is related to the technical field of water conveying, more particularly to one kind in long distance water transmission pipeline system is used for
The device of long range water supplying pump system protecting water hammer.
Background technology
Long range water supplying pump system often due to pumping accident and occur water hammer accident, cause pressure pipeline, water pump, valve
Etc. wrecking, supply water and interrupt, cause heavy losses.The pump-stopping water hammer of water supplying pump system is to have barotropic wave after first having step-down ripple
Transient process, if can prevent that pressure from reducing in time, just can effectively reduce pressure rise.
At present, prevent that the method that pressure is reduced in Calculations of Hydraulic Transient from there are two kinds：One kind is the water filling into pipeline, another
It is the gas injection into pipeline.The protecting water hammer measure of the water filling into pipeline is mainly surge tower (case) and air tank；Noted into pipeline
The protecting water hammer measure of gas is mainly air valve.Surge tower (case) and air tank high cost, operational management inconvenience；Air valve only has
When the pressure in pipeline is less than atmospheric pressure could gas injection, therefore its protecting water hammer effect is limited.
Utility model content
For above-mentioned problem of the prior art, the utility model, which provides a kind of long range water supplying pump system water hammer that is used for, to be prevented
The device of shield, in Calculations of Hydraulic Transient, can timely and effectively suppress water hammer harm.
The technical scheme that the utility model is provided：
, there is local high spot in aqueduct, in institute in a kind of device for long range water supplying pump system protecting water hammer
The device for connecting protecting water hammer on local high spot by service valve is stated, the device of the protecting water hammer includes compressed air cylinder, subtracted
Pressure valve, air valve, gas pipeline, magnetic valve, the device of the protecting water hammer are set and the tank connected venting channels of compressed air,
Venting channels are pressure-reducing valve, gas pipeline, magnetic valve A and are linked in sequence, and pass through magnetic valve B connection air valves.
It is preferred that technical scheme, it is twice that the device of the protecting water hammer, which sets venting channels,.
The beneficial effects of the utility model are：The utility model is in Calculations of Hydraulic Transient, when pressure is small in aqueduct
In depressurize valve outlet setting pressure when into pipeline injecting compressed air, timely and effectively suppress water hammer harm, with surge tower and
Air tank is compared, and the installation cost is low；Compared with air valve, the minimum pressure of device installation site, protecting water hammer effect are improved
It is really good；Long range water supplying pump system water hammer is protected in gas injection, can more timely and effectively prevent the pressure drop of gas injection cross-section pressure pipeline
It is low, so as to suppress water hammer boosting, it is ensured that rate is high, more safe and efficient.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the arrangement of the utility model embodiment 1.
The structural representation of the device of the protecting water hammer of Fig. 2 embodiments 1.
The structural representation of the device of the protecting water hammer of Fig. 3 embodiments 2.
Wherein:1st, compressed air cylinder；2nd, pressure-reducing valve；3rd, gas pipeline；4th, magnetic valve A；5th, air valve；6th, magnetic valve B；7、
Service valve；8th, gas；9th, aqueduct；10th, water pump；11st, intake pool；12nd, discharge bay；13rd, air valve.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Based on this practicality
Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, the scope of the utility model protection is belonged to.
According to Fig. 1, in long range water supplying pump system, intake pool connects water pump by aqueduct, and water pump is with going out
Connected between pond by aqueduct, water pump draws water from intake pool and deliver to discharge bay along aqueduct, due to the difference of physical features,
There are multiple local high spots in aqueduct, each local high spot is respectively mounted service valve before setting air valve, air valve, selects it
In a local high spot, on the local high spot pass through service valve connect protecting water hammer device.
According to Fig. 2, as embodiment 1 protecting water hammer device include compressed air cylinder, pressure-reducing valve, air valve,
Gas pipeline, magnetic valve, the device of protecting water hammer is set is decompression with the tank connected venting channels of compressed air, venting channels
Valve, gas pipeline, magnetic valve A are linked in sequence, and pass through magnetic valve B connection air valves.
According to Fig. 3, in order to further improve security performance of the present utility model, to the further optimization of apparatus structure,
As the device of the protecting water hammer of embodiment 2, it is twice that the device of protecting water hammer, which sets venting channels, increases the number of pressure-reducing valve
Amount, as standby.
Operation principle of the present utility model：Service valve is only closed in overhaul of the equipments, in system during normal operation, maintenance
Valve is opened, and magnetic valve A is closed, and magnetic valve B is opened, and air valve can normal work；During pumping accident, service valve is opened, and is arranged on
Magnetic valve B before air valve is closed, and the magnetic valve A after pressure-reducing valve is opened；Set when pipeline pressure is less than decompression valve outlet
During constant-pressure P, pressure-reducing valve is opened to pipeline gas injection, and when pipeline pressure is more than decompression valve outlet setting pressure P, pressure-reducing valve is closed
Close, stop to pipeline gas injection；After Calculations of Hydraulic Transient terminates, magnetic valve A is closed, and magnetic valve B is opened, gas in aqueduct
Body is discharged by air valve.
The above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model is disclosed
Or replace, it should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with the power
The protection domain that profit is required is defined.
