Glass lining feeding use pneumatic valve maintenance and installation of the note

glass lining feeding pneumatic valve overview
glass lining feeding pneumatic valve equipment is high silicon content in the vitreous glaze. Through about ℃ high temperature coating on metal bond. It has good mechanical properties and corrosion resistance, and can prevent the medium and the metal ions affect pollution products instead of role, and the surface is bright and clean, wear-resisting, there is a certain thermal stability. In chemical, petroleum, metallurgy, food processing, pharmaceutical, pesticide, fuel and other industries widely used.

glass lining feeding pneumatic valve main equipment
(1) performance, corrosion resistance,
general inorganic acid, organic acid, weak alkali ( Ph值P≤℃≤) And agent of organic medium.
, the strength of hydrochloric acid, nitric acid, water and other corrosive medium is better than stainless steel.
, it is forbidden to use fluoride ion liquid ( Such as HF) Also can't use strong alkali and phosphate ( > temperature > ℃, the concentration ﹪)
(2), heat resistance, allowing the in - Using (between ℃ to + ℃ Heat-resistant radically less than ℃)
(3), and has a smooth surface. Difficult to binding material, easy to clean.
(4), good insulation, glass material has good insulation, mm thick glass under the volts breakdown and won't be conductive.
(5), impact resistance, impact resistance performance for g/cm smaller, and therefore should be avoided when using hard objects.
6, compression:. MPa

glass lining feeding use pneumatic valve maintenance and installation of the note
and all contact with the porcelain face when decorate place must use asbestos or four fluorine soft mat, etc. Use tools cannot with porcelain face impact or friction, more can't use metal tools shovel.
tightening up and around the lock screw is in force, to prevent the crack porcelain porcelain face stress unevenness. Feeding pneumatic valve screw should often maintain lubrication, prevent rust.
is a liquid, flows through the medium only, ranging from hard particles into liquid, prevent the enamel surface fuzz or congestion, etc.
and open failure and ministries should be paid attention to during the installation of screw force balance, lift ( Activities) Whether or not flexible.
and in various parts of the enamel surface seal center position shall be maintained. Uniform pressure, to prevent leakage.
, if found to have leaks, when using, should immediately check whether the sealing device is relevant, not the handwheel made with iron bars, stick tightly, so as not to damage parts.
to be blocked, discharging, banning the use of metal rod or hard tools.
alternately, should try to avoid acid-base medium make ( In addition to the neutralization reaction medium) To avoid shorten life.
, according to the dielectric performance and life, should be regularly check the top four fluorine pneumatic valve body sealing ring and orifice of four fluorine chips. If found damaged should be replaced in a timely manner to use again.
pneumatic valve, slurry, if found damaged should immediately stop using porcelain face. Can use special coating repair the affected or entrust relevant enamel production units to do first.
