VALVE
PROTECTION SYSTEM
General
Valve
bodies are made of brass alloy and can get damaged, if it is hit against any
object. This may develop leak of LPG
creating serious hazards. To prevent this, protection for the valve is provided
by means of valve protection ring assembly on the top of the cylinder.
Safety Cap
Valve
outlet is fitted with safety cap manufactured out of Delrin Dupont 500 material
to avoid damage to internals of the LPG valve and also to arrest the entry of
dust particles and dirt inside the valve assembly. Safety cap should
be put on to the valve at all times except for filling of the cylinder
at the plant and usage of the cylinder
at the customer’s premises. If the
safety cap is not fitted on to the valve, valve may get damaged due to entry of
dust particles or dirt into the valve and may cause leakage of LPG through the
valve. Hence, the safety cap is also
considered as a protection for the leakage of the valve. Safety cap can withstand a
maximum working pressure of 2.45 M Pa of LPG and as such safety cap is
very useful to stop the leakage from the valve, in case there is any leak
through the valve seat.
ULTRAS0NIC VALVE CLEANING
EQUIPMENT
Each and
every valve housing after machining are being cleaned by the valve
manufacturers with Utrasonic Cleaning Euipment to remove any oil,
grease, chips from the valve housing before assembly. The solution used in Ultrasonic Cleaning
Equipment is Trichloroethylene. In this
system, there are three chambers. The first
chamber contains liquid trichloroethylene which vibrates at ultrasonic
frequency. The second chamber is of liquid trichloroethylene without any
frequency and the third chamber is a vapour chamber.
