Stainless steel flanged gate valve

タイトルまたは説明

Theopening and closing part of stainless steel flanged gate valve Z*1W is wedge disc, the movement direction ofwedge disc isperpendicular to the fluid direction, the gate valve can only be fully open and fully closed, can t be adjustedorthrottled.Wedge disc has two sealing surfaces, the two sealing surfaces ofmost common mode of gate valve form wedge, the wedge anglevarywith the valve parameters,Usually the angle is *0 , and it is2 °*2 when medium temperature is not high. The wedge disc of wedge gate valve can be made into one piece,which iscalled the rigid wedge disc; It can also be made into wedge disc which produces small quantities of deformation in order to improve its manufacturability, to make up the deviations of sealing surface angle arising during processing, this wedgeisdisc called the flexible wedge disc.

 

Stainless steel flanged gate valve is widely used asopening and closing devices to connect orblock the medium ofoil, steam pipeline in petrochemical, power plants, etc.

Stainless steel flanged gate valve has the following advantages:

1,Compact structure, reasonable design, good rigidity, smooth channel,lowflow coefficient

2,Sealing surfaceis madeof stainless steel andhard alloy,it haslong service life.

3,Flexible graphite is used as packing, sealing is reliable,and operation isflexible.

4,The drivingmodes are manual, pneumatic, electric, gear drive

5,The construction are flexiblesinglewedge disc, rigid single wedge disc and double wedge disc type
