1, see fit and use rubber or molecular compound plastic soft tightly closed manufacturing diaphragm, tight sealing ability is better. Because the diaphragm for wearing parts, should be periodically change depending on the nature and the medium of special. 。 Diaphragm valve temperature generally used by the diaphragm and body lining material limit, its temperature range is about - 50～175℃。 Q: the diaphragm valve is that some unique place? A: one of the most picturesque place MaoJian unique local diaphragm valve is put in the lower body inner cavity and the upper cover cavity is separated, the located above the diaphragm of the stem and disc parts from corrosion medium, such as eliminating the packing tightly closed structure, and do not initiation media leakage. 2, the diaphragm material limit, the diaphragm Industrial Valves is suitable for use in the occasion of relatively low pressure and temperature is not high. This, the valve stem don't have to see fit and use no matter what is the mode of separate tightly closed, unless as a safety equipment used in the curb harmful medium. Common diaphragm valve has a rubber diaphragm valve, diaphragm valve lining fluorine, no lining plastic diaphragm valve diaphragm valve, molecular compounds. Diaphragm valve has simple structure, only by the body, diaphragm and valve head is a combination of three major components. 4. General is not suitable for temperature is higher than 60 degrees and organic solvent and strong oxygen medium pipeline, also not suitable for make in high pressure pipeline. Diaphragm valve structure of the way large mixed with normal valve, Marine valve is a new type of valve, the cut-off valve is a special way, it's opening and closing is a diaphragm, made with soft materials within the valve body cavity with the valve cover cavity and drive components separated, is now widely used in various fields. The valve to facilitate rapid disassembly and maintenance, change the diaphragm can be finished inside presence and instant. Pneumatic diaphragm valve is within the body and cover is equipped with a flexible diaphragm or combination of diaphragm, the thing is its are shut and diaphragm articulation of a compression device. Diaphragm valve's strengths is its driving mechanism and media channel is separated, pay security office medium of pure, and also to prevent pipeline medium quality impact drive mechanism office device possible. 3, according to the structure pattern can be divided into: the diaphragm valve house type, straight flow, by type, straight through, ram and six 90 - degree Angle type; Generally for flange petition petition mode; According to the driving form can be divided into manual, electric and pneumatic three, there is divided into pneumatic drive often open, often closed and reciprocating three. Seat can be weir shape, also can be straight flow tube wall. Diaphragm valve, because the office media contact only the diaphragm and the valve body, both can see fit and use a variety of different materials, because the medium of the Industrial Valves can ideally contain a variety of office, especially for medium with chemical corrosive or suspended particles. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
