G6B41J normally closed pneumatic rubber lined diaphragm valve uses and main performance specifications
1. This series of diaphragm valves can be applied to different fluid medium pipelines at different temperatures according to different visual wrapping materials, as a control medium flow opening and closing mechanism.
2.G6B41J normally closed pneumatic rubber lined diaphragm valve, the recommended range of use of various visual wrap materials:
Visual wrap material (code)Applicable temperatureApplicable medium
Hard rubber (NR)-10 o C ~ 85 o CIn addition to strong oxidants (such as sales acid, chromic acid, concentrated sulfuric acid and hydrogen peroxide and other organic solvents), hydrochloric acid, fluorosilicic acid, formic acid and phenolic acid, hydrochloric acid, 30% sulfuric acid, 50% hy-drofluoric acid, 80% phosphoric acid, alkali, salt, gold-plated solution, sodium hydroxide, potassium hydroxide, neutral salt solution, 10% sodium hypochlorite, wet chlorine gas, ammonia water, most alcohols, Organic acids and aldehydes, etc.
Soft rubber (BR)-10 o C ~ 85 o C]Has good wear resistance. Mainly used for less than 50% of sulfuric acid, sodium hydroxide, potassium hydroxide, neutral salt bath solution and ammonia solution, cement, clay, cinder ash, granular fertilizer and wear strong solid fluid, thick mucus of various concentrations.
Butyl adhesive (IIR)-10 o C ~ 120 o CResistant to corrosion and wear. Capable of most organic acids, alkali and hydroxide compounds, inorganic salts and inorganic acid elemental gases, alcohols, aldehydes, ethers, ketones, esters and so on.
Neoprene adhesive(CR) -10 o C ~ 120 o CAnimal oils, vegetable oils and inorganic lubricants and corrosive mud with a wide range of pH values, good wear resistance.
Cast iron is not coated-40 o C to 100 o CNon-corrosive media
Recommended range of diaphragm materials:
Diaphragm material (code)Suitable temperatureSuitable medium
Butyl glue (Grade B)-40 o C ~ 100 o CGood acid and alkaline resistance. 85% sulfuric acid, hydrochloric acid, hydroflu-oric acid, phosphoric acid, loaded base and a variety of esters.
Natural glue (Grade Q)-50 o C to 100 o CFor purifying water, inorganic salts, and diluting inorganic acids.

G6B41J normally closed pneumatic rubber lined diaphragm valve structure characteristics and principle of action
2. The big difference between diaphragm valve and other valves is that: the structure of no stuffing box is used; Rubber diaphragm can make the corrosive medium in the flow channel and all the driving components in a completely isolated state, so as to eliminate the usual valve "running, taking, dripping, leakage" and other drawbacks.
3. Because the diaphragm valve's flow path is smooth and the flow resistance is small, a larger flow rate can be obtained.
4. The surface of the valve body cavity of the diaphragm valve appears to have a variety of rubber for choice. Therefore, it has superior corrosion resistance characteristics.
5. Because the seal is elastic rubber diaphragm. Therefore, it also has good sealing and small closing force.
6. The valve is composed of body, valve cover, disc, stem, diaphragm and other driving parts.
7. The opening and closing of the valve is achieved by rotating the hand wheel. The diaphragm valve is marked on the upper end of the valve cover with the display color of the opening or closing position of the valve to indicate the opening and closing stroke of the valve. When the handwheel is placed clockwise, the handwheel is moved down, and the valve disc then drives the diaphragm down to cut off the path; On the contrary, the valve is opened, and the color is revealed.
8. The diaphragm valve adopts the standard: in accordance with the provisions of GB12239, and meets the requirements of BS5156.
