Q: the diaphragm valve using the unique place a: the diaphragm valve is one of the earliest regulator, described it as the unique place: ( 1) Soft rubber diaphragm valve can truncate the media do not leak. Because fluorine molecular compound plastic rubber corrosion resistance, heat resistance, and the ball core ball valve is far better than the stiffness of diaphragm valve diaphragm ten times, one hundred times, so the proposal in corrosion medium truncated and regulating occasions, try to choose diaphragm valve, selection of corrosion resistant lining fluorine ball valve, butterfly Industrial Valves, and all four fluorine single-seat valves. 。 ( 5) Like a tired trying to piece, forcing it fold up and down, easy to damage, because the diaphragm is a treacherous parts, valve caused by fixed number of year of the survival of a shorter, it is fatal. ( 7) Special requirements are: corrosion resistant material more and more, especially at the end of the age of 80 molecular compound lining fluorine plastics processing, rubber fluorine ball valve. ( 2) Because of a certain corrosion resistance of the rubber, before the age of 60, also no better corrosion resistant material, it has been commonly as a corrosion resistant material to popularization and application, even has also extended down to this day. After choose after we introduce water disposal of special ball valve, the problem was solved by beautifully, the survival of the fixed number of year for 7 ~ 8 years, ordinary can also be used to 3 ~ 5 years. ( 3) Simple flow, a self-cleaning 'utility', can be used in the medium of untidy. ( 6) Closing, medium utility to the diaphragm upwards crest, injustice, balance force is bigger, demand greater thrust actuator, because of this, be sure to choose especially large and bulky, heavy actuator, the valve weight very heavy, is 2 times the size of ball valve, is a fully functional ultra light valve 3 - 4 times. Not prevent an example explained: in a water treatment system, water desalination device using the valve, at the beginning of 10, whether it's still overseas domestic device, chooses the molecular compound lining fluorine plastic diaphragm valve, the use of the survival of the fixed number of year is a year or so long, short, 3 ~ 6 months, because of this, constantly change the diaphragm. Marine valve ( 4) Open special properties, but as a corrosion resistant regulator is unavailable, have to use the nature of the quick opening special local before, the short work schedule, adjust the quality is poor. Because of this, the author in recent years are put forward: should eliminate the diaphragm Industrial Valves, ball valve, fully functional ultra light Industrial Valves instead. 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.
