When stifled valve is moved up, water inlet pipe water inlet can be blocked, so, when being poured water into water pump, be unlikely to Water is set to be flowed into along pump water inlet by water inlet pipe water inlet in intake pool;After water pump normally starts, then by stifled valve to Lower movement, until being in contact with intake pool bottom of pond, now, the crossbeam of truss bottom just moves to the truss groove of intake pool bottom of pond It is interior, meanwhile, now block up valve and play a part of eliminating bottom of pond whirlpool, stable intake pool streamflow regime;Described truss groove is arranged in water In intake pool bottom of pond below pump water inlet pipe, its length and width is advisable with the crossbeam that can put truss bottom into;So, water is worked as During pump normal work, the crossbeam of truss bottom is placed in it always;Described truss is the member structure for fixed stifled valve.
When water pump needs work, the gate valve on pumping line is first shut off, restarts Electric nut or manual nut, Move up screw rod, screw rod drives stifled valve to move up by truss, until pump water inlet water inlet is all blocked.So, it can lead to The water irrigating hole for crossing water pump top is poured water into water pump, under gravity, is poured into the water of water pump and can be flowed into pump water inlet, Due to blocking up the plugging action of valve, into the water of pump water inlet, would not be flowed into intake pool, but be stored in water always In pump water inlet pipe, meanwhile, the gas in water inlet pipe is discharged into air by water pump water irrigating hole, when pouring into the certain water of water pump, water Will be gradually filled with one section of pumping line before pump water inlet, water pump inner chamber and gate valve, water inlet pipe, water pump inner chamber and The gas in one section of pumping line before gate valve is all discharged into air, completes the requirement of water pump water-filling.When water pump water-filling is complete Cheng Hou, blocks water pump water irrigating hole, can normally start water pump;After water pump normally starts, restart electric or hand nut, make Screw rod is moved down, until making truss bottom enter in the truss groove at intake pool bottom.Now, water inlet pipe directly with the water in intake pool Source is communicated, then, and slowly can enter to open water in gate valve, intake pool can enter water inlet pipe by water inlet pipe water inlet, then by Water pump is transported to pumping line, and water can just be transported to required place, water pump is carried out normal work.
When stifled valve drops to minimum point, because stifled valve is just in immediately below water inlet pipe water inlet, it can disappear well The generation in whirlpool (attached bottom whirlpool) in water removal, plays a part of stable intake pool streamflow regime.So, stifled valve has two your writings herein With.
When next water pump is restarted, said process is repeated, the requirement of water pump water-filling is completed.
, then, can be in outlet pipe after the completion of the first task if being provided with non-return valve or gate valve on pumping line A certain amount of water is stored, then later water pump water-filling, first stifled valve can be moved up, water inlet pipe water inlet is blocked, then Water in outlet pipe is poured in down a chimney in intake pump inner chamber and water inlet pipe, so, the requirement of water pump water-filling can also be completed;Later water Pump priming, can be completed by above-mentioned steps.
