G45J DC rubber-lined diaphragm valve

Parts list: 1. Valve body 2, valve body lining 3, diaphragm 4, valve disc 5, valve stem 6, valve cover 7, handwheel design and manufacturing: GB122239
Structure length: GB12221, JB1688
Flange connection size: GB4216, JB78
 

 

First, G45J DC rubber-lined diaphragm valve uses:
专用于控制非腐蚀性或一般腐蚀性介质,阀体内腔表面无衬里或覆有可供选择的各种橡胶,适用于不同工作温度和流体管路。 G45J DC rubber-lined diaphragm valve is specially used to control non-corrosive or general corrosive media. The inner surface of the valve body is not lined or covered with a variety of rubbers, which is suitable for different operating temperatures and fluid pipelines.
Applicable temperature: ≤85 ℃, ≤100 ℃, ≤120 ℃ (according to the lining and diaphragm material)
Pressure level: PN0.6, 1.0, 1.6

 

2. G45J DC rubber-lined diaphragm valve material:

Body: cast iron, ductile iron, carbon steel, stainless steel
Valve cover: cast iron, ductile iron, carbon steel, stainless steel
Lining: unlined, rubber
Diaphragm: Rubber
Disc: cast iron, carbon steel
Stem: Carbon steel, Stainless steel Handwheel: Cast iron

Third, G45J DC rubber lined diaphragm valve test:

Lining layer: electric spark detection
Test and inspection according to GB / T13297 standard
Nominal pressure: PN (Mpa)
Body: PN 1.5
Seal: PN 1.1

Structural features of G45J DC rubber-lined diaphragm valve:

是一种特殊形式的截止阀; Weir enamel diaphragm valve is a special form of globe valve;
1. Elastically sealed opening and closing parts to ensure no internal leakage;
2. Streamlined flow channel makes pressure loss small;
3. There is no stuffing box, so there is no leakage;
4. The valve body and the cover are separated by an intermediate diaphragm, so that the valve cover and valve stem parts above the diaphragm are not affected by the medium;
5. The diaphragm can be replaced, and the maintenance cost is low;
6. The diversity of lining materials can be applied to various media and has good corrosion resistance.
