Description

A new type of gas top pressure water supply equipment

technical field

The utility model relates to a water supply equipment, in particular to a novel gas top pressure water supply equipment.

Background technique

At present, the emergency fire water supply generally adopts automatic air supply type air pressure water supply equipment. The air pressure water supply equipment has an air pressure tank, and the air pressure tank is divided into an air chamber and a water chamber. Generally, the volume of the air chamber accounts for 2/3~ of the total volume of the air pressure tank. 4/5, so in order to increase the water supply, the designed air pressure tank has a large volume, causing the air pressure tank to occupy most of the space in the pump room in actual use. Moreover, when the equipment is running, the compressed gas presses out the water during the process of dropping from the highest working pressure to the lowest working pressure, so the water supply pressure fluctuates greatly. There is also a gas top pressure water supply equipment, which consists of a pneumatic water tank, a stabilized pressure It consists of a pump unit, a stabilized air compressor, a control cabinet, an air stop device, an air supply air compressor, a top pressure device, and a high-pressure gas cylinder group. Although this kind of gas top pressure water supply equipment improves the shortcomings of the automatic air supply type air pressure water supply equipment, the air chamber in the air pressure tank is separated, and the air chamber is formed by the high pressure cylinder, but because the air chamber adopts the high pressure cylinder, The high-pressure gas cylinder is a steel seamless gas cylinder with a maximum volume of 80L. Usually, a set of gas top pressure water supply equipment needs to be equipped with a considerable number of gas cylinders, which is extremely inconvenient to maintain. And in the process of reducing the gas from high pressure to low pressure, the decompression performance requirements are stricter.

Contents of the invention

The purpose of this utility model is to solve the above-mentioned problems existing in the gas top pressure water supply equipment in the prior art, and provide a new type of gas top pressure water supply equipment. The utility model designs a new type of gas top-pressure water supply equipment, which includes a pneumatic water tank, a pressure-stabilizing pump unit, a pressure-stabilizing air compressor, a control cabinet, an air stop device, an air supply air compressor, and a top pressure device, and is characterized in that: The air pressure water tank is connected with a stabilized air compressor, and the air pressure water tank is also connected with a top pressure device. The air stop device is connected to the stabilized pump unit, and the stabilized pump unit is connected to the fire water supply pipe. The utility model has the advantage that the air chamber is independently set up with a medium-pressure gas cylinder, thereby reducing the volume of the pressure tank; after the compressed gas is pressure-maintained and decompressed, the gas pressure can be kept constant to realize constant-pressure water supply. After the gas cylinder adopts the welded gas cylinder, the maximum volume can be designed to 1000L, and the decompression performance is stable and safe when the top pressure gas is reduced from the medium pressure to the low pressure.

Detailed ways

The figure includes an air pressure water tank 1, a pressure stabilizing pump unit 2, a pressure stabilizing air compressor 3, a control cabinet 4, an air stop device 5, an air supply air compressor 6, and a top pressure device 7. It is characterized in that: the air pressure water tank 1 A stabilized air compressor 3 is connected to the top, and a top pressure device 7 is connected to the air pressure water tank 1. The top pressure device 7 is connected to a medium-pressure gas cylinder group 8, and the medium-pressure gas cylinder group 8 is also connected to a supplementary air compressor 6. , the air pressure water tank 1 is connected with the pressure-stabilizing pump unit 2 by the air-stopping device 5, and the pressure-stabilizing pump unit 2 is connected with the fire-fighting water supply pipe 9.

When the equipment is put into operation, the pressure-stabilizing pump unit 2 supplies water from the fire-fighting water supply pipe 9 to the air pressure water tank 1, and stops when the liquid level reaches the set water level. Add pressure to the air pressure water tank 1, and when the pressure reaches the set pressure upper limit, the stabilized pressure air compressor 3 stops running. If the system pressure drops to the lower limit of the set pressure due to pipe network leakage and other reasons, the pressure-stabilizing air compressor 3 will work repeatedly to maintain the system pressure. When a fire occurs, the top pressure device 7 is opened, and the compressed air of the medium pressure cylinder group 8 enters the air pressure water tank 1, and the water in the air pressure water tank 1 is pushed into the fire water supply pipe 9, so as to meet the certain requirements of fire water supply. Pressure, to ensure the normal use of fire hose and fire fighting equipment. The compressed air of the medium-pressure cylinder group 8 is provided by the supplementary air compressor 6 .
