Abstract

The invention discloses a pressure tank, which relates to the technical field of high-pressure storage equipment, and includes: a pressure tank body and a pressure adding / relieving device. The pressure tank body includes a tank body, an inner barrel body and a cover body, and both the tank body and the inner barrel body are open at one end. The tank is sleeved outside the inner barrel and the openings of the tank and the inner barrel are set in the same direction. The cover is detachably connected to the tank and can seal the inner barrel and the tank. The pressure adding / relieving end of the pressure adding / relieving device can Pressurize or release pressure into the inner barrel and / or tank; the pressure tank body is also provided with a liquid inlet and a liquid outlet, the inner barrel is made of corrosion-resistant materials, and the tank is made of high-pressure resistant materials. The invention provides Improve the cleanliness of the stored chemicals and prolong the service life of the pressure tank.

Description

technical field [0001] The invention relates to the technical field of high-pressure storage equipment, in particular to a pressure tank. Background technique [0002] Acidic or alkaline agents are used in the wet cleaning process, and the storage and cleaning output of these agents are carried out in pressure tanks; especially in the wet process in the semiconductor field, the cleanliness requirements of pressure tanks Higher, the existing pressure tank directly stores the medicament in the tank coated with anti-corrosion material on the inner wall, and the anti-corrosion material is easy to fall off, causing the tank to be easily corroded by the medicament, and impurities are mixed in the medicament, and the cleanliness is not high. Therefore, need badly a kind of novel pressure tank.
