Basic structure of pneumatic ball valve
The pneumatic ball valve is a kind of curved capsule made of and wire, commonly known as pneumatic tube, corrugated pneumatic tube, pneumatic ball valve, leather tiger, etc. Both ends of the capsule shall be connected with two steel plates to form a compressed air chamber. The cable itself does not provide the load bearing capacity, but is completed by the compressed air filled into the capsule.
The number of curved sacs is usually 1~3, but it can also be designed and manufactured into 4 or more than 5 curved sacs according to needs, and two pneumatic ball valves can also be used together under certain conditions.
Pneumatic ball valve is also called air stroke regulator and air vibration isolator according to its performance and point. The end structure of the existing curved bladder pneumatic ball valve can be divided into three categories according to the connection mode: one is the fixed flange connection type. The size of the edges at both ends of the pneumatic ball valve is equal to or slightly smaller than the curved bladder. The large outer diameter is equal to or slightly smaller than the large outer diameter. After drilling several holes, the flange ring and end plate are used for fastening connection; The other is the looper flange connection type. The size of the edges at both ends of the pneumatic ball valve is much smaller than that of the large outer diameter of the curved capsule. There is no need to drill holes, and a flange ring and an ordinary end plate are used to fasten the connection The third type is self sealing type, without flange connection, it is pressed into the end plate, and self sealing when filled with compressed air.
The flange sealing forms of the end and connecting plate of the pneumatic ball valve are mainly JBF, GF and HF.
Main purpose of pneumatic ball valve
Pneumatic ball valves are mainly used in the paper machine industry for stroke adjustment and tension control of correctors, calenders, presses, scrapers, nets and other parts. In addition, they are also used in all parts requiring valves, shock isolation and stroke control in automobile, train, construction, chemical, mechanism, installation and military industries. At present, the main field of pneumatic ball valve is vehicle suspension system, which can realize automatic adjustment of body height and keep the body height unchanged; The application of pneumatic ball valve on lifting equipment. As the lifting element of lifting equipment, the pneumatic ball valve overcomes the traditional shortcomings of lifting equipment, requires no maintenance, has a long service life, and is easy to operate and replace.
