With-lock butt welding connection bellows globe valve
We adhere to customer-oriented principles and drive innovation through technology, providing comprehensive services from product selection to technical consultation, helping enterprises enhance steam system efficiency and create greater value.
Detailed Introduction
Structure and main features of bellows valves
1The double sealing of packing and bellows realizes zero leakage.
2.The body and bonnet are connected by studs with good technological performance.
3.The stem of the valve has the packing box of ordinary valves,and under this packing box,the moveable sealing part bellows is installed inside the bonnet,so that the medium is sealed in the valve cavity outside the stem and cannot enter the packing box.Therefore,the valve is more reliable than ordinary valves in the prevention of leakage,ensuring sealing between stem and bonnet
4.The bellows is designed to be located in the cavity of bonnet,avoiding direct erosion with media and enhancing service life of the bellows.
5.The bellows adopts 2-6 times overlapping,Ensure to use Pressure avoiding valve leakage due to single-layer damage of the bellows and prolonging service life of the valve.
6.As the bellows is designed to be relatively long,the valve is featured by high opening height,reduced fluid main resistance and low flow resistance coefficient.
