Problems solved by technology

However, slow inflation is a common problem of current expansion tanks, especially when gas needs to be replenished, the air valve intake is slow, and the rapid change of air temperature and pressure will lead to unstable performance of the air bag, leakage and other accidents, and the space in the bag is fixed. It is difficult to meet the working environment with various space requirements

Embodiment 1

[0019] Such as figure 1 As shown, a split-type fast-filling bladder type expansion tank is composed of a tank body 2, a bag 3, and an air bag. The bag 3 is inside the tank body 2, and the air bag is a main air bag 12 and a sub-air bag 13; The main airbag 12 is connected with the main airbag inflation valve; the sub-airbag 13 is connected with the split inflation valve 11; the bottom of the tank body 2 is provided with a flange 5 .

[0020] Furthermore, the main airbag inflation valve is divided into a top inflation valve 1 and a side inflation valve 8 .

[0021] Furthermore, the top inflation valve 1 is located at the top of the tank body 2; the side inflation valve 8 is located at the side of the tank body 2.

[0022] Furthermore, a protective cover 4 is provided on the inflation valve.

[0023] Furthermore, the tank body 2 is provided with a pressure sensor 10 .

[0024] Furthermore, a reinforcement plate 6 is provided on the flange.

[0025] Furthermore, the flange and ...

Abstract

The invention belong to the field of pressure vessel equipment, in particular to a split-type fast-inflating bladder-type expansion tank. The split-type fast-inflating bladder-type expansion tank is characterized by consisting of a tank body, a bladder and air bags, wherein the bladder is arranged inside the tank body; the air bags comprise a main air bag and a sub air bag; the main air bag is connected with main air bag inflation valves; the sub air bag is connected with sub inflation valves; and a flange is arranged at the bottom part of the tank body. The split-type fast-inflating bladder-type expansion tank disclosed by the invention has the characteristics that the size is small; partitions are divided; the expansion tank is flexible and varied, is capable of inflating fast, and cannot be easily damaged; meanwhile, the expansion tank has a protection function.

Description

technical field [0001] The invention belongs to the field of pressure vessel equipment, and in particular relates to a split type fast-filling bladder type expansion tank. Background technique [0002] Expansion tanks are used in thermal systems (boilers, air conditioners, heat pumps, water heaters, etc.), mainly to absorb the volume of the working medium due to temperature changes; The water hammer impact caused by such opening and closing, as well as a small amount of water replenishment at night, make the main pump of the water supply system dormant, thereby reducing power consumption and prolonging the service life of the pump. When the expansion tank is used in the system, because the system pressure is higher than the pressure of the pre-charged gas, part of the working medium will enter the air bag (for the diaphragm type, it will enter the tank) until a new balance is reached. When the system pressure is restored When the pressure rises, the system pressure is great...
