Problems solved by technology

Because the water is pressed out by the compressed gas from the highest working pressure to the lowest working pressure when the equipment is running, the water supply pressure fluctuates greatly.
There is also a full-displacement top-pressure pressure tank, which uses...

Embodiment Construction

[0006] The figure includes an air supply port 1, a safety valve 2, a liquid level gauge 3, a water level detector 4, a top pressure port 5, an inlet / outlet port 6, and an air pressure tank 7. It is characterized in that: the top pressure port 5 of the air pressure tank 7 is formed by The air pipe 8 is connected to the pressure-sustaining valve 9, and the pressure-sustaining valve 9 is connected to the medium-pressure cylinder 10 by the air pipe 8.

[0007] The air pressure tank 8 is connected with the external air supply pump; the water inlet / outlet 6 is connected with the water supply pump and the fire-fighting pipe network to form a full displacement gas top pressure water supply equipment.

[0008] When the equipment is put into operation, the water supply pump supplies water to the air pressure tank 7. When the liquid level reaches the set water level, the system pressure does not meet the set requirements at this time, and the air supply pump supplies air to the air pressu...

Abstract

The invention relates to a new all-replacement jacking pressing tank, comprising air supply opening, safety valve, liquid level gauge, water level detector, jacking pressing port, water inlet/outlet and pressure tank. It is characterized in that the jacking pressing port is connected with pressure holding valve by air pipes and the pressure holding valve is connected with medium-pressure air bottle. The merit of invention is that air chamber is moved away from the air pressure tank to carry compression out so that the volume of air pressure tank and after compressed air is decompressed by pressure holding to realize water supply in constant pressure. After medium-pressure air bottle is used, air bottle can adopt welding air bottle. The maximum volume can achieve to 1000L and the decompression performance of jacking pressing air is stable and safe from medium pressure to low pressure.

Description

technical field [0001] The invention relates to a constant-pressure water supply equipment for gas replacement, in particular to a new full-displacement top-pressure air tank. Background technique [0002] At present, the air pressure tank structure in the air pressure water supply equipment has an air chamber and a water chamber inside, and the volume of the air chamber usually accounts for 2 / 3~4 / 5 of the total volume, and the air pressure tank occupies most of the space in the pump room during use. Because the water is pressed out by the compressed gas from the highest working pressure to the lowest working pressure when the equipment is running, the water supply pressure fluctuates greatly. There is also a full-displacement top-pressure pressure tank, which uses a high-pressure gas cylinder. Since the high-pressure gas cylinder is a steel seamless gas cylinder with a maximum volume of 80L, a full-displacement gas top-pressure pressure tank usually needs to be equipped wit...
