Flange Diaphragm is a special form of cut-off valve , appeared in the 1920s . Its opening and closing pieces is a separator made ??of a soft material , the body cavity and the valve cover cavity and drive components are separated , it said diaphragm .
Flange Diaphragm is a special form of cut-off valve , appeared in the 1920s . Its opening and closing pieces is a diaphragm made ??of soft material ,
The body cavity and the cavity separated from the valve cover and drive components , it said diaphragm .
The most prominent feature is the lower part of the body cavity and diaphragm valve cover upper cavity separated , so that at the top of the diaphragm valve stem , the valve and other parts from corrosion, eliminating the packing structure, and no media leaks .
Manual Flange Diaphragm features:
1 , the use of soft rubber or plastic diaphragm seal making , sealing well . Since the diaphragm is wearing parts should be replaced periodically depending on the medium characteristics .
2 , is limited by the diaphragm material , diaphragm for low pressure and relatively high temperature applications.
3 , diaphragm structure can be divided into: house , DC type , cutoff type, straight-through, ram type and angled six kinds ; usually in the form of flanged connections ; press drive can be divided into manual, electric and pneumatic three, including pneumatic drive is divided into normally open , normally closed and reciprocating three.
4 generally not suitable for temperatures above 60 degrees and the organic solvent supply line and strong oxidizing medium, and it is not used in the high pressure line
Diaphragm is in a fluid system 1.3 × 10-5 ~ 2.5X106Pa used to turn on or off the flow valve.
Manually flange diaphragm parameters:
Leakage rate : ≤ 1.3 × 10-5Pa. L / S;
Material : 304,316 L;
Working medium: air , water, oil ;
Working temperature : Viton -30 ℃ ~ +150 ℃;
Powered by compressed air driven drive screw , the spool up and down movement , while pulling the diaphragm moves up and down to make it close and open . Features : Compact , simple, small , beautiful appearance ; switch has guided , smooth motion ; closing torque , long life , ≥ 30 million times ; diaphragm compression can automatically adjust compression uniform , reliable seal ; diaphragm mounted into the spool using push- easy replacement ;
Lined diaphragm advantages:
1 . The valve from the valve body , bonnet , stem , valve, diaphragm , other drivers parts and other components.
2 when the valve opening and closing means is connected to a drive shaft of motor stem nut , so that axial movement of the valve stem to drive the valve lift achieved .
(3) When the power supply is interrupted when a fault occurs , and the opening and closing of valves needed under emergency conditions, should first "hand - electric switch handle " Convert to manually tag engraved with the position, and then to make flash door opened by rotating the handwheel closed . When clockwise , the valve can be closed ; otherwise open .
4 When the need to restore electric operation must be " switched handle " Convert to mark engraved on the location of the electric , electric operation can be carried out .
