Simply understand the advantages and disadvantages of pneumatic stop valve?

Pneumatic stop valve this type of valve is mainly for the purpose of reversing or stopping the medium Because of its superior sealing type and cleanness, it is widely used in various fields of health industry Advantages of pneumatic stop valve: 1 Usually there is only one sealing surface, good manufacturing process, easy to maintain 2 The structure of the valve body of pneumatic stop valve includes straight through type, direct current type and right angle type Straight through is a common structure of Zui, but its fluid resistance Zui is large Direct flow fluid has less resistance, and is mostly used for fluid with solid particles or high viscosity The right angle valve body is mostly forged, which is suitable for the stop valve with small diameter and high pressure 3 Good sealing performance, small friction between sealing surfaces and long service life 4 Small working stroke and short opening and closing time 5 In the process of opening and closing, the friction of the sealing surface is smaller than that of the gate valve, which is wear-resistant 6 Simple structure, convenient manufacture and maintenance Disadvantages of pneumatic stop valve: 1 The design of bellows seal completely eliminates the disadvantages of aging and quick leakage of common valve stem packing seal It not only improves the energy efficiency, increases the safety of production equipment, reduces the maintenance cost and frequent maintenance, but also provides a clean and safe working environment 2 Poor regulation performance 3 It is not suitable for medium with particles, high viscosity and easy coking 4 The fluid resistance is large, and the force required for opening and closing is large Through the above content, I hope to help you understand the pneumatic stop valve
