Diaphragm gas pressure tank with gas compensation device

Abstract

The invention relates to the technical field of gas pressure tanks, and discloses a diaphragm gas pressure tank with a gas compensation device. The diaphragm gas pressure tank comprises a tank body and a gas supplement valve, and also comprises an external gas supplement unit connected with the gas supplement valve; the gas supplement valve comprises a gas supplement tube and a valve core; the external gas supplement unit comprises a gas supplement cylinder and a gas supplement bag that are in butt-joint with the gas supplement tube; the gas supplement bag is arranged in the gas supplement cylinder, and is filled with gas; and when gas pressure in the tank body is lower than the standard gas pressure, the valve core is opened, and gas in the gas supplement air enters the tank body throughthe valve core. The external gas supplement unit is in butt-joint with the gas supplement valve to supplement gas in the tank body automatically to stabilize gas pressure..

Description

technical field [0001] The invention relates to the technical field of pressure tanks, in particular to a diaphragm pressure tank with a gas compensation device. Background technique [0002] Such as figure 1 , the existing air pressure tank is mainly composed of a tank body 1 and an inner tank 2. High-pressure gas is stored between the tank body 1 and the inner tank 2, and the inner tank 2 is used to store water. During the water supply process, when the water pressure in the system decreases , the high-pressure gas squeezes the water in the liner 2 to make up the system, thereby reducing the change of the water pressure in the system and improving the stability of the water pressure in the system. [0003] There are following defects in the above-mentioned prior art scheme: [0004] During long-term use, the high-pressure gas between the tank body and the air bag will leak, which makes it difficult to compensate the water pressure in the system normally. Currently, a mea...

Problems solved by technology

[0004] During long-term use, the high-pressure gas between the tank body and the air bag will leak, which makes it difficult to compensate the water pressure in the system normally. Currently, a measuring gauge for measuring air pressure and a compensating pressure gauge are used on the tank body. The trachea is continuously inspected manually. When the air pressure is lower than the standard air pressure, the tank is inflated through the air supply pipe. However, the above process requires manual inspection every day, which is troublesome.
