The opening and closing part of the three-way diaphragm valve is a diaphragm made of soft material, which separates the inner cavity from the inner cavity of the valve cover and the driving parts. The diaphragm made of rubber or plastic soft seal has better sealing performance. Because the diaphragm is a fragile part, it should be replaced periodically according to the characteristics of the medium. The three-way diaphragm valve is used for medium containing hard suspended substance; since the medium of the three-way diaphragm valve only contacts the valve body and diaphragm, there is no need for packing box, no leakage of packing box, and no corrosion to the stem.
Design and manufacture: GB122239
Structure length: GB12221, JB1688
Flange joint dimensions: GB4216, JB78
G49W (non lining), G49J (lined rubber) three way diaphragm valve use
Usage: This valve is specially used 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, less than 120 degrees, or less than 150 degrees (according to lining and diaphragm material).
Pressure level: PN1.0
Three way diaphragm valve material
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
Stem: carbon steel, stainless steel
Hand wheel: 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, diaphragm 3, disc 4, stem 5, valve cap 6, handwheel.
