Description

Horizontal tank pump pipe network superimposed water supply equipment

technical field

The utility model belongs to the field of water supply equipment, in particular to a pump pipe network superimposed water supply equipment in a horizontal tank.

Background technique

The traditional water supply method is inseparable from the reservoir. The pressure of the water under pressure in the tap water pipe network enters the reservoir and the pressure becomes zero, and then pressurizes from zero, resulting in a lot of waste of electric energy. Pipe network superimposed water supply equipment is an ideal energy-saving water supply equipment. It can be directly connected to the tap water pipe network without any side effects on the tap water pipe network. It can directly superimpose water supply on the basis of the pressure of the municipal pipe network to save energy. And it also has many advantages such as fully enclosed, pollution-free, small footprint, quick installation, reliable operation, and convenient maintenance. However, connecting the external stabilizing tank and the stabilizing tank with the water inlet and outlet pipelines and valves is complex and occupies a large area. Patent CN201538990U discloses a new type of pipe network superimposed water supply equipment for a horizontal pump in a tank. The top of the steady flow tank is connected with a bypass soft joint, a bypass butterfly valve, a bypass check valve, and a bypass pipeline. It is the water inlet pipe, which is connected to the flow direction display window and the water inlet gate valve. All the pumps are installed in the steady flow tank, and the water outlet valves are all above the steady flow tank. Bypass pipes and all-round anti-negative pressure controllers are set between the pumps. , its design is concentrated, symmetrical, compact, and occupies a small area, but the structure of its flow direction display window has the side effect of reducing water pressure, and it cannot intuitively display the pressure changes of the main water inlet pipe and the main water outlet pipe, which is not conducive to operation control.

The bypass pipeline, bypass check valve, bypass butterfly valve and bypass soft joint are connected in sequence. The pump in the tank and the water pump outlet check valve , the water pump outlet butterfly valve, and the water pump outlet soft joint are connected sequentially. The main water outlet pipe is connected with the bypass soft joint and the water pump water outlet soft joint. The remote pressure gauge A is connected to the main water outlet pipe, the tank support frame is arranged at the bottom of the steady flow tank, the built-in bucket of the water pump is connected to the bottom plate, and a sewage valve and a sewage pipe are arranged in the middle, and it is characterized in that: it also includes Remote pressure gauge B, the remote pressure gauge B is connected to the main water inlet pipe, the inner wall of the flow direction display window is provided with two opposite slideways, the center position of the flow direction display float is provided with a slide arm, and the slideway The arm head is located in the slideway.
