Flanged Plunger globe valve made by valve, valve cap, stem, plunger, guide, sealing ring, composed of parts such as hand wheel (Figure). When the hand wheel rotation, the plunger driven through the stem in the direction set in the upper and lower reciprocating motion, so that the plunger tip cone oblique cone with the completion of the valve seat to open and close the function.
Plunger in the valve between the used and the sealing ring fit, by adjusting the preload bolt in the flange, so that seal ring by compression of the lateral force generated in the hole with the valve plunger cylindrical sealing surface, thereby ensuring the valve door seal. Put an end to the internal leakage.
Since the seal ring used strong elasticity, high wear resistance of the new non-toxic sealing material, so sealing reliable, durable, thereby increasing the life of the valve.
Combination of the valve plunger valve leakage-free gate valve advantages and characteristics of fast, as a novel structure, use of a wide range of new products. Its advantages are far better than the ordinary cut-off valve.
Plunger globe valve installation and maintenance
The company's factory cut-off valve plunger are conducted in strict test pressure, acceptance. Simply use the outside and the hole cleaned cavity without strip and clean and replacement.
The valve can be installed in any location, medium body on the flow direction, see arrow.
After a period of use, seal ring wear, if there is leakage of the valve must be closed, and then in the flange bolts evenly tightened up a little leakage as well as to the next,
Bolt should not blindly be too restrictive. At the same time, the replacement should be sealed to prevent the plunger and the newly installed ring cracks and bumps.
