Design and manufacture: GB122239
Structure length: GB12221, JB1688
Flange joint dimensions: GB4216, JB78
Application of G45J direct current rubber lined diaphragm valve
The valve is specially designed to control non-corrosive or general corrosive media. There is no lining on the inner surface of the valve body or covered with a variety of optional rubber. It is suitable for different working temperatures and fluid pipelines.
Applicable temperature: less than 85 degrees, less than 100 degrees, or less than 120 degrees (according to lining and diaphragm material).
Pressure level: PN0.6, 1, 1.6
Material Science
Body: cast iron, ductile iron, carbon steel, stainless steel.
Bonnet: cast iron, ductile iron, carbon steel, stainless steel.
Lining: no lining, rubber.
Diaphragm: Rubber
Disc: cast iron and carbon steel.
Stem: carbon steel, stainless steel handwheel: cast iron.
test
Lining layer: EDM test
Test and inspection according to GB/T13297 standard
Nominal pressure: PN (Mpa)
Valve body: PN * 1.5
Sealing: PN x 1.1
Structural characteristics
Diaphragm valve is a special stop valve.
1. The opening and closing parts of the elastic seal ensure that there is no internal leakage.
2, streamlined flow path makes the pressure loss small.
3, there is no stuffing box, so there is no leakage.
4. The valve body and cover are separated by the middle diaphragm so that the valve cover above the diaphragm and the valve stem parts are not eroded by the medium.
5, the diaphragm can be replaced and the maintenance cost is low.
6. The variety of lining materials can be applied to all kinds of media and has good corrosion resistance.
Parts list: 1, body 2, valve body lining 3, diaphragm 4, disc 5, stem 6, valve cap 7, handwheel.
