The structural characteristics of a bladder type accumulator are as follows: the main function of a bladder type accumulator is to store capacity and replenish isolation fluid for the system. Its structure mainly consists of a steel shell, an air valve, a capsule, and a liquid interface of a one-way valve. 1. Accumulator shell: It is a pressure vessel forged or welded from chromium molybdenum steel or carbon steel, and its design and manufacturing comply with relevant international standards. For special-purpose accumulators, the accumulator housing can be nickel plated or made of stainless steel. 2. Capsule: It is an important component of a capsule accumulator. Capsules come in several different formulations to adapt to different working media and temperature requirements, and are specifically labeled for special purposes. 3. Oil valve: The standard oil used for hydraulic oil is made of high-strength alloy steel, while for chemical and aqueous media, it is made of stainless steel to ensure the longest service life and corrosion resistance. 4. Bacterial valve: can prevent the capsule from squeezing out the liquid interface, while allowing the liquid to flow automatically. In high-pressure systems, mushroom shaped discs are used, while in low-pressure series, a perforated disc is used. 5. Air valve: All bladder type accumulators have an air valve for inflating the accumulator.
