Self-balancing air supply type high level storage direct water supply equipment

Abstract

The invention provides self-balancing air supply type high level storage direct water supply equipment, which consists of a non-negative pressure flow stabilizing tank, an air supply tank, a control valve, a switching valve, a water pump, a control cabinet and an air pressure storage tank, wherein a clapboard is arranged in the non-negative pressure flow stabilizing tank, and divides the non-negative pressure flow stabilizing tank into two parts, namely a flow stabilizing chamber and an adjusting chamber; the flow stabilizing chamber is connected with a water inlet pipe; water output by the flow stabilizing chamber is connected to the water pump through a pipeline; the top of the adjusting chamber is provided with the air supply tank; the top of the air supply tank is provided with an air filter and an air stop device; a water outlet pipe is provided with an outlet pressure cage; a water outlet manifold is connected with a water utilization pipe network; and the air pressure storage tank is arranged at the lowest water utilization rate point of the water utilization pipe network. The equipment adopts self-balancing air supply, and the air pressure storage tank is arranged at the lowest water utilization rate point, so that the flow can be adjusted, the pressure of the pipe network can be stabilized, small-flow water supply can be realized, effects of supplying water stably and saving energy during operation are achieved, the adjustable volume of the system can be increased, and investment and materials are saved.

Description

1. Technical field [0001] The invention relates to a water supply device, in particular to a self-balancing air-supplementing high-level regulation and storage direct water supply device connected in series on a pipe network. 2. Background technology [0002] There are two types of water supply equipment in the prior art, one is the indirect water supply equipment, the water pump takes water from the pool and the water tank to pressurize it, so as to avoid the direct connection of the water pump to supply water and have the function of regulating and storing a certain amount of water. There are pools and water tanks so that it occupies a large area, requires high investment, cannot use the pressure of the pipe network, does not save energy in operation, and has problems such as water pollution; the other type is direct water supply equipment, which is based on the pressure of the water inlet pipe. The use of water pumps for superimposed water supply can make use of the origi...

Problems solved by technology

[0002] There are two types of water supply equipment in the prior art, one is the indirect water supply equipment, the water pump takes water from the pool and the water tank to pressurize it, so as to avoid the direct connection of the water pump to supply water and have the function of regulating and storing a certain amount of water. There are pools and water tanks so that it occupies a large area, requires high investment, cannot use the pressure of the pipe network, does not save energy in operation, and has problems such as water pollution; the other type is direct water supply equipment, which is based on the pressure of the water inlet pipe. The use of water pumps for superimposed water supply can make use of the original pressure of the pipe network, but when the pressure of the water inlet pipe is lower than the minimum set pressure, the pump will be stopped and the water will be cut off, and it cannot well adapt to the energy-saving operation of the system at small flow rates. When the number of water pumps In the process of increasing and decreasing, it will also cause fluctuations in the outlet water pressure, etc.
