Description

A stabilized water supply equipment

technical field

The utility model relates to a water supply equipment for stabilizing pressure.

Background technique

Traditional fire regulated water supply equipment generally uses cast iron water pumps and is placed outside the water tank. When the pump is used for the first time or restarted after the water is cut off, there must be a self-priming method to clear the air in the pump. However, when water is supplied, the water supply pressure is often unstable, which cannot ensure a stable water pressure in the water pipe network, resulting in discontinuous and stable water supply, high noise, and cumbersome installation.

Contents of the invention

The technical problem to be solved by the utility model is to provide a water supply equipment for stabilizing the pressure to ensure the stability of the fire-fighting water supply pressure of the water pipe network.

In order to solve the above technical problems, the utility model takes the following technical solutions:

A stabilized water supply equipment, including a pressure tank, a No. 1 water pump, a No. 2 water pump, an electric control cabinet, a pool, a check valve and a gate valve. The electric control cabinet is connected to the No. 1 water pump and the No. 2 water pump. The pipelines are connected with the gate valve, No. 1 water pump, gate valve, check valve, and air pressure tank in turn. The pool is also connected with the gate valve, No. 2 water pump, gate valve, check valve, and air pressure tank through the No. 2 pipeline in turn. The air pressure tank is connected with the water supply pipeline. connected.

A safety valve, a pressure gauge and a water flow indicator are arranged on the pipeline communicating between the air pressure tank and the water supply pipeline.

The air pressure tank is a diaphragm type air pressure water tank.

The utility model has the advantages of compact structure, small occupied area, convenient installation and maintenance, safety and reliability, and is widely applicable to the stabilized water supply of fire hydrants, fire sprinkler water supply systems, domestic and production water supply systems.

Description of drawings

Accompanying drawing 1 is the schematic diagram of pipeline connection of the utility model.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a stabilized water supply equipment includes a pressure tank 1, No. 1 water pump 2, No. 2 water pump 3, electric control cabinet 4, pool 5, check valve 6 and gate valve 7, electric control cabinet 4 and The No. 1 water pump 2 and the No. 2 water pump 3 are connected, and the pool 5 is connected with the gate valve 7, the No. 1 water pump 2, the gate valve 7, the check valve 6, and the air pressure tank 1 through the No. 1 pipeline 11, and the pool 5 is also connected through the No. 2 pipeline. The pipeline 12 is sequentially connected with the gate valve 7, the No. 2 water pump 3, the gate valve 7, the check valve 6, and the air pressure tank 1, and the air pressure tank 1 communicates with the water supply pipeline. A safety valve 8 , a pressure gauge 9 and a water flow indicator 10 are arranged on the pipeline communicating between the air pressure tank 1 and the water supply pipeline. In addition, the air pressure tank is a diaphragm type air pressure water tank, which can be used for a long time after being inflated once, and has good airtight performance.

The utility model can also be provided with more water pumps, not limited to two water pumps. When working, when the water pump supplies water to the water pipe network, when the water consumption of the water network is less than the water supply of the water pump, the water pressure in the air pressure tank gradually increases. When the pressure on the pressure gauge reaches the set maximum working pressure, the electric control cabinet Send a signal to make one of the water pumps stop working. With the reduction of the water stored in the air tank, when the pressure of the water pipe network drops to the set minimum pressure, the electric control cabinet sends out a signal to make the other pump work, so as to achieve Set the purpose of automatic rotation and continuous water supply within the working pressure range to achieve stable pressure supply.
