Gemo Fa (diaphragm valve) is a special form of cut-off valve, appeared in the 1920s. It is one of the hoist with soft materials made of divide, the inner cavity with the valve and valve cover intracavity drive parts separated, it said Ge Mofa.
Ge Mofa the characteristics are as follows:
The most prominent feature is to divide the lower and upper Valve intracavity intracavity valve cover off, so that the divide at the top of the stem, the valve and other parts from corrosion media, save the packing seal structure, and will not produce medium leakage .
1, using rubber or plastic sealing produced by the soft diaphragm, sealing better. As for the lack of wearing parts, depending on the medium of regular replacement.
2, the divide material constraints, Ge Mofa apply to low pressure and relatively high temperature of occasions.
3, Ge Mofa the structure can be divided into:-style housing, DC-The deadline for style, straight-through processing, ram-and-six right-angle; forms are usually connected to flange connection; way can be divided into the driver manual, electric and gas Three dynamic, pneumatic drive is divided into open-type, and often closed and three reciprocating.
4. Should not be used for general temperature above 60 degrees and transmission of organic solvents and strong medium of the pipeline, we should not at the higher pressure of the use of the pipeline |
