Outlet pipe, now container 3 use as the auto-pneumatic cylinder of the first water pump 4.Be equivalent to no adjusting means formula non-negative pressure method of water supply to set
Standby.
When water inlet manifold 11 hydraulic pressure be higher than with water pipe 5 need to pressure when, continuously open the first valve 7, the 3rd valve
9, the second water inlet pipe connects uses water pipe 5, is a kind of direct supply system.
Fig. 2 is water supply system of the present utility model, is a kind of basic water supply system form.Enter including first in Fig. 1
Water pipe 2, intake valve 1, container 3, the first water pump 4, use water pipe 5.Also include the auto-pneumatic cylinder 13 of the first water pump 4.
The effect of auto-pneumatic cylinder 13, first is pressurize, and the first water pump 4 can be made to stop when idle or flow are too small
Machine；Second is when the water consumption drastic change with water pipe 5, can supplement or balance the flow of drastic change, stablize the operation of the first water pump
State.The feature of described flow drastic change, when flow is big, relative amplitude is little, and impact is little；When flow is little relatively
Amplitude big, impact is big.In Fig. 1, when container 3 is connected to the suction hose of booster water pump 4 (or include the second water pump 10, afterwards with)
When, the water level of container 3 is low, below peak level, water inlet manifold 11 or big with the resistance of water pipe 5 is described, flow is big；Work as container
During the outlet pipe that 3 are connected to increase water pump 4, more than peak level, water inlet pipe 2 or little with the resistance of water pipe 5, flow are described
Little, just meet this feature.
