Embodiment 1

[0025] Such as figure 1 As mentioned above, the pressure tank includes a tank body 1 and a tank cover 2 fixed at the opening of the tank body 1. The tank body 1 is provided with an air bag 3, and the edge of the opening of the air bag 3 is clamped between the tank body 1 and the tank cover 2. between. The tank cover 2 is provided with a water inlet 2a that communicates the inner cavity of the air bag 3 with the outside world, and forms a closed air cavity-4 between the air bag 3 and the tank body 1, and the tank body 1 is provided with an air inlet 1a, and enters The air port 1a communicates with the air chamber one 4 .

[0026] Specifically, as figure 1 and figure 2 As shown, a barrel body 5 is fixedly connected to the outside of the tank body 1 , and the barrel mouth of the barrel body 5 faces the tank body 1 . In this embodiment, it is preferable that the tank body 1 and the barrel body 5 are sealed and fixedly connected by welding. At this time, an air cavity two 6 is...

Embodiment 2

[0033] The structure and principle of the second embodiment are basically the same as those of the first embodiment, except that the one-way valve includes a valve body, and the valve body is threadedly connected with the intake pipe 9 .

Abstract

The invention provides a pressure tank and belongs to the field of pressure vessels. The pressure tank comprises a tank body and a tank cover fixedly arranged at an opening of the tank body, an air bag is arranged in the tank body, the edge of an opening of the air bag is clamped between the tank body and the tank cover, a water inlet is arranged on the tank cover, an air cavity I is formed between the air bag and the tank body, an air inlet is arranged on the tank body, a barrel body is fixedly connected outside the tank body, an air cavity II is formed between the barrel body and the tank body, and the air cavity I and the air cavity II communicate with each other through the air inlet; an exhaust pipe is fixed in the air inlet, an air inlet pipe is screwed outside the outer end of the exhaust pipe, a through hole is formed in the barrel body, the outer end of the air inlet pipe penetrates through the through hole and is positioned outside the barrel body, and a seal is formed between the air inlet pipe and the barrel body through a sealing ring. By rotating the air inlet pipe, the inner end of the air inlet pipe can press against the edge of the air inlet of the tank body and partition the air cavity I and the air cavity II, a one-way mechanism enabling the air cavity I and the air cavity II to be communicated in a one-way mode is arranged in the air inlet pipe, and the exhaust pipe is positioned between the one-way mechanism and the air bag. The pressure tank is good in practicability.

Description

technical field [0001] The invention belongs to the field of pressure vessels and relates to a pressure vessel. Background technique [0002] The pressure tank is used in the closed water circulation system to balance the water volume and pressure, avoid frequent opening of the safety valve and frequent replenishment of the automatic water replenishment valve. [0003] Existing pressure tanks generally include a tank body and a tank cover fixed at the opening of the tank body. An air bag is arranged in the tank body, and the edge of the opening of the air bag is clamped between the tank body and the tank cover. The inner chamber communicates with the outside world, and a closed air chamber 1 is formed between the air bag and the tank body. The tank body is provided with an air inlet, and the air inlet communicates with the air chamber 1. [0004] The volume of the existing pressure tanks is fixed, which is only applicable to certain specific working conditions, and the prac...
