Abstract

The invention discloses direct-connected non-negative pressure water supply equipment. The equipment comprises an inlet sluice valve, an inlet butterfly valve, an anti-backflow apparatus, an inlet pressure transmitter, a diaphragm three-way exhaust valve and other components, wherein the inlet pressure transmitter is connected between the inlet sluice valve and the inlet butterfly valve; a filter is connected between the inlet butterfly valve and the anti-backflow apparatus; a flow metering device is connected between the anti-backflow apparatus and a soft joint; a control valve is connected between the soft joint and a flow stabilizing tank; the diaphragm three-way exhaust valve and a sluice valve are connected with the flow stabilizing tank; a water intake pressure transmitter is connected between the sluice valve and a first butterfly valve; the first butterfly valve, a water pump, a check valve, a flexible joint and a second butterfly valve are connected in sequence; an air pressure tank is connected with the second butterfly valve; and an outlet sluice valve and an outlet butterfly valve are connected with the second butterfly valve. The equipment also comprises a pressure stabilizing pump which is connected with the air pressure tank. The equipment has the positive effects of reducing the starting frequency of the water pump and more effectively saving the energy.

Description
