Non-return valve 7 is arranged in the downstream of force (forcing) pump 1 in pumping plant communicating pipe 2, and the non-return valve 7 is located at moisturizing communicating pipe 8 and pump
It stands the upstream of 2 junction of communicating pipe, the circulating direction of non-return valve 7 is force (forcing) pump 1 to pumping plant communicating pipe 2 to connect the one of main pipeline 3
End.
The diameter of moisturizing communicating pipe 8 is more than or equal to the diameter of pumping plant communicating pipe 2.
Reservoir storage when 10 normal pool level of conditioning tank is able to satisfy after the power-off of force (forcing) pump 1, and water supplements in conditioning tank 10
Into pumping plant communicating pipe 2, conditioning tank 10 does not occur hollow within maintenance 30s~60s time.
The embodiment of the present invention provides a kind of and flow by gravity function water hammer-resistant arragement construction progress control method, institute simultaneously
The method of stating includes:
As shown in Fig. 2, pressure reducing valve 6 is automatically closed, and is supplied by main pipeline 3 when 3 upstream water level of main pipeline is higher
Water realizes that flow by gravity supplies water.
As shown in figure 3, can not be supplied water using flow by gravity, non-return valve 4 closes automatically when 3 upstream water level of main pipeline is lower
It closes, pressure reducing valve 6 is opened, and to 10 moisturizing of conditioning tank, force (forcing) pump 1 is opened, supplied water by pumping plant communicating pipe 2.
As shown in figure 4, hydraulic control disc valve 9 receives signal and opens immediately when 1 power loss of force (forcing) pump causes serious water hammer, adjust
Alleviate the negative pressure in pumping plant communicating pipe 2 by carrying out moisturizing moisturizing communicating pipe 8 into pumping plant communicating pipe 2 in section pond 10；Non-return valve 7
It by the control of hydraulics, voluntarily opens, protects force (forcing) pump 1.
As shown in figure 5, water flow flows into conditioning tank 10 by hydraulic control disc valve 9 and carries out pressure release, check when water flow is flow backwards
Valve 4 is since hydraulic action is voluntarily closed, if flowing into main pipeline 3, drop by pressure reducing valve 6 when 10 water level of conditioning tank reaches preset water level
Low extreme water hammer pressure.
Water hammer-resistant arragement construction designed by the present invention is higher constantly using gravity flow water supply in water intaking reservoir head, is taking
It is supplied water when water reservoir head is lower using water pump pressurization, effective solution water system takes into account flow by gravity and water pump pressurization supplies
Two kinds of methods of operation of water, and can be switched between two kinds of methods of operation according to upper pond water level, operation energy consumption is reduced, is dropped
Low operating cost.
The main reason for 1 power loss of force (forcing) pump causes serious water hammer is: 1 power loss of force (forcing) pump causes pumping plant communicating pipe 2 after stopping
The high vibration caused by great change of pressure pole dissolves now larger negative pressure after force (forcing) pump 1 can add the structures such as press pump 1 and cause brokenly
Bad property influences.Therefore it is provided with moisturizing communicating pipe 8 and hydraulic butterfly valve 9, can be when 1 power loss of force (forcing) pump cause serious water hammer, liquid
Control dish valve 9 receives signal and opens immediately, and conditioning tank 10 is alleviated by carrying out moisturizing moisturizing communicating pipe 8 into pumping plant communicating pipe 2
Negative pressure in pumping plant communicating pipe 2, to mitigate water hammering.Non-return valve 7 will receive the control of hydraulics at this time simultaneously, voluntarily
It opens, protects force (forcing) pump 1.
And when water flow flow backwards when, water flow by hydraulic control disc valve 9 flow into conditioning tank 10 carry out pressure release, non-return valve 4 due to
Hydraulic action is voluntarily closed, if flowing into main pipeline 3 by pressure reducing valve 6 when 10 water level of conditioning tank reaches preset water level, is reduced maximum
Water hammer pressure, to further decrease the influence of water hammer.
