Description
Technical field
The present invention relates to a kind of water plug of automatic water filling exhaust, belong to agricultural water conservancy field.
Background technology
Most of existing centrifugal pump water plug is all using the centrifugal pump water plug of assembling bottom valve, and bottom valve is installation
In a kind of one-way cock of pump water inlet entrance, water pump installation bottom valve adds the resistance of water pump, reduces the effect of water pump
Rate, power attenuation is increased, reduce the suction of water pump, and bottom valve easily phenomena such as not closing, rubber cushion is rotten occurs and caused leak
Water, virtually add maintenance capacity, therefore, remove bottom valve be reduce centrifugal pump draw water work when pipeline local head loss side
One of method.
If there is gas to enter wherein during pump work is centrifuged, the efficiency of centrifugal pump will be reduced, so that shadow
Ring and draw water efficiency, be that elbow more than impeller is added using water inlet pipe in the past, or water inlet pipe mouth is upwarped, but exist elbow or
Pipe upturned portion must have a manual exhaust valve, during each turn on pump or need manual exhaust during work, waste time and energy, and
And if exhaust is not clean or will influence the normal work that centrifugal pump draws water not in time.
Therefore, a kind of water plug of automatic water filling exhaust is suggested.

Preferably, the angle of the bend pipe (3) is 50 °~60 °.
Further, the 1/10~1/7 of a diameter of outlet pipe (8) diameter of the return pipe.
Further, it is in funnelform water filling port (11) that the free end of the water injection pipe (1), which is preferably provided one,.
During actual use, directly water pipe can be connected on water injection pipe (1), funnelform water filling port (11) can also be passed through
Water filling work is carried out, opens ball valve (2), makes water clean full of in water inlet pipe B (7) and pump case, air is excluded, is then shut off ball
Valve (2), centrifugal pump (9) is opened, centrifugal force is produced under the rotary action of centrifugal pump (9) impeller, will be implanted into water inlet pipe B (7)
Discharged with the diversion in pump case from outlet pipe (8), negative pressure is now produced in the centrifugal pump (9) so as to by the water at water inlet (5) place
Suck in, then open back-water valve (BWV) (10), in centrifugal pump (9) normal pumping operation process, flow to the small portion at outlet pipe (8) place
Divide water to be returned to again in water inlet pipe B (7) from return pipe (6), reach the purpose of automatic water filling, as long as having recirculation water always, with regard to energy
Enough realize self-bleeding purpose, after the end of job of drawing water, due to the tilting action of water inlet pipe B (7), make water inlet pipe B (7) and from
Still diversion during next draw water can be used as with the presence of water in heart pump (9), it is not necessary to again plus water, significantly mitigate
Labor intensity, easily realizes automatic management.
Further, it is in horn-like water inlet (5) that the lower end of the water inlet pipe A (4), which is provided with,.
Further, the return pipe (6) is provided with back-water valve (BWV) (10).
Compared with prior art, the present invention realizes centrifugal pump on the premise of removing bottom valve and reducing local head loss
The purpose that automatic water filling is vented when drawing water, the present apparatus is simple in construction, and in addition to needing manually to add water before the first task, centrifugal pump exists
During normal work can automatic watering reach the effect of exhaust, improve operating efficiency, reduce labor intensity.
