Description

Welcome to purchase discount source bellows seal valve from our company, which is one of the best China bellows seal valve manufacturers and suppliers.

Application of Bellows sealed valve

Bellows seal valves are mainly used in flammable, explosive and toxic conditions. The bellows seal valves achieved sealing by the double effect of packings and bellows, which achieve zero leakage.

 

Structure of the Bellows seal valve

Bellows seal valves are consists of the valve body, the valve stem, bellows, lower stem, pin and other components. There is a pair of spiral track grooves on both the upper and lower stem ( same spiral direction) . The two pins are fixed to the stem and the pin can have a free movement on the track groove between the lower stem and valve stem. The lower stem is connected with the ball to achieve valve opening and closing control operation.  

 

Characteristic of Bellows seal valve

Bellows seal valve is a relatively new structure. The bellow seal valves effectively solve the problem of bellows rotation action in ball valve sealing. By using the two spin in the same spiral groove, the bellows seal valve makes the external force three times transformation in the delivery process. The two spiral grooves in the same rotation structure of bellow seal valve makes easy processing. And there is no need to be formulated when assembly, which effectively meets the modern requirements of easy operation, simple assembly, reliability and safe operation.
