The valve sealing requirements
Valve
sealing performance refers to the sealing parts of valve's ability to
prevent leakage of medium, it is the most important technical
performance index of the valve.There are three sealing parts of the
valve : open-close part and seat the contact point between the two
sealing surface;Packing cooperate with stem and packing gland;The joint
of the body and bonnet.One former place called internal leakage of
leakage, known as the closed lax, it will affect the valve truncation
medium capacity.For block valves class, the internal leakage is not
allowed.After the two called the outside leakage, the medium from
leaking to the outside of the valve from the valve.Leakage would cause
material loss, environmental pollution, serious when still can cause
accidents.For flammable and explosive, toxic or radioactive medium,
leakage is not allowed, so the valve must have a reliable sealing
performance.

Camlock couplings use notes
Camlock couplings use has many notes,today Shanghai K&G machinery Co.,Ltd will tell you as follows:
1. Please don't used to apply fluid outside of the fluid.
2. When using don't exceed the maximum working pressure limit.
3. Do not use outside the operating temperature range, causing the sealing material to prevent wear or leaks.
4.Don't punch, bending, stretching, prevent breakage.
5. Do not mix the metal powder or sand and dust and other places, to prevent adverse or leak job.
6. Screw type of installation, the installation do not exceed the maximum tightening torque to prevent damage it.
7. Do not use a hose with a crack, to prevent leakage or loss caused.
8. Such as for there is vibration, shock machines will cause a decrease in durability.
9. Using the fluid must be filtered through the filter clean fluid.
10. Do not disassemble
