Background technology
At present, original pressure that no-negative-pressure water supply equipment can utilize tap water pipe network because of it, and is able in water supply pump station
Popularization and application, but the no-negative-pressure water supply equipment of prior art turns into a closed system because eliminating pond with pipe network, and equipment is dashed forward
During right termination of pumping, backwater water hammer in equipment water side be present, water water hammer be present in arrival end, two water hammers from opposite direction simultaneously
It is applied on no-negative-pressure water supply equipment, harm is larger.
The content of the invention
Technical problem to be solved in the utility model is：New waterproof hammer functional device is provided, it solves existing
The problem of water hammering is in equipment during no-negative-pressure water supply equipment unexpected termination of pumping.
Technical problem to be solved in the utility model takes following technical scheme to realize：
New waterproof hammers functional device into shape, is arranged between tap water pipe network and user's pipe network, including flow regulator, current stabilization
Compensator, bidirectional compensator, variable frequency pump and Intelligent control cabinet, the tap water pipe network are connected with flow regulator, the stream
Amount adjuster is connected with steady flow compensator, and the steady flow compensator bottom sets two delivery ports, and two delivery ports pass through two-way
Compensator is connected, and the bidirectional compensator is connected by the water inlet end of pipeline and variable frequency pump, the water side of the variable frequency pump
Be connected with user's pipe network, the end of variable frequency pump is provided with pressure sensor PS, the Intelligent control cabinet respectively with pressure sensing
Device PJ, steady flow compensator, variable frequency pump, pressure sensor PS and the electrical connection of user's pipe network.
As preferred embodiment, be disposed between the tap water pipe network and flow regulator main valve, y-type filter,
Backflow preventer and pressure sensor PJ.
As preferred embodiment, the Intelligent control cabinet is PLC control cabinet.
The beneficial effects of the utility model are：By setting pressure sensor PS, Intelligent control cabinet and variable frequency pump, normally
During water supply, after variable frequency pump soft start, pump rotary speed is stepped up, and constant pressure is maintained after reaching setting pressure, is switched to power frequency fortune
After turning, restart second water pump, when system pressure is more than setting pressure, frequency converter is reduced to lower-frequency limit, and water pump is by work
Frequency pump is switched to variable frequency pump, and webmaster pressure continues to keep stable, and for system after delay, water pump enters resting state, until shut down,
Pressure moment be effectively prevent up to big or too small, equipment water inlet end is eliminated and water side forms water hammering to equipment, danger
Evil equipment.

Embodiment
In order to be easy to understand to technological means of the present utility model, creation characteristic, reached purpose and effect, tie below
Conjunction is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, new waterproof hammers functional device into shape, it is arranged between tap water pipe network 1 and user's pipe network 2, including stream
Adjuster 3, steady flow compensator 4, bidirectional compensator 5, variable frequency pump 6 and Intelligent control cabinet 7 are measured, tap water pipe network 1 is adjusted with flow
Section device 3 is connected, and flow regulator 3 is connected with steady flow compensator 4, and the bottom of steady flow compensator 4 sets two delivery ports 41, and two go out
The mouth of a river 41 is connected by bidirectional compensator 5, and bidirectional compensator 5 is connected by pipeline with the water inlet end of variable frequency pump 6, variable frequency pump
6 water side is connected with user's pipe network 2, and the end of variable frequency pump 6 is provided with pressure sensor PS8, Intelligent control cabinet 7 respectively with
Steady flow compensator 4, variable frequency pump 6, pressure sensor PS8 and user's pipe network 2 electrically connect.
Main valve 9, y-type filter 10, backflow preventer 11 are disposed between tap water pipe network 1 and flow regulator 3
With pressure sensor PJ12, Intelligent control cabinet 7 is PLC control cabinet.
Water hammer-resistant functional device is made up of pressure sensor PS8, Intelligent control cabinet 7 and variable frequency pump 6, and variable frequency pump 6 wraps
Include water pump and frequency converter, during normal water supply, after the soft start of variable frequency pump 6, pump rotary speed steps up, and water yield increase, reaches
Maintain constant pressure after setting pressure, when frequency reaches 50Hz, do not reach setting pressure also, frequency converter after being delayed after a while,
After being switched to power frequency operating, be delayed second water pump of variable frequency starting, and constant pressure is maintained after reaching pressure, when system pressure is more than setting
During pressure, frequency converter is reduced to lower-frequency limit, and after delay determines, system cuts off the general pump being currently running successively, now net
When pipe pressure can also keep stablizing, variable frequency pump is switched to, such webmaster pressure continues to keep stable, and system is after delay, water pump
Into resting state, until shutting down, whole system carries out Isobarically Control to water outlet pipe network, and avoiding pressure from occurring, moment is excessive and mistake
Small situation.
