Multivalve, a multi-purpose valve, is connected to an LPG tank. It controls the level and output of LPG to the tank ……
Multivalves can be broken down into A or B type. A type multivalves include 25 atmospheric relief valves. Type B multivalves do not have a relief valve. Multivalves have a mechanical structure which performs the following functions.
Filling
During fueling, LPG passes through the fuel pump and through the multivalft. To avoid long filling times, a good multivalve must not be too resistant to LPG passing through it.
Fill Limit
The tank should not exceed 80% capacity due to safety and current standards. LPG vapor is used to fill the remaining 20%. The tank’s liquid expands with temperature and doesn’t fill the entire volume. The multivalve has a float that can cut off LPG flow at the maximum level to stop the filling process.
level meter
Two magnets are used to measure the level of LPG in the tank. One of these magnets can be found inside the tank. It is connected to the devices that are connected to the floating. The second magnet is located outside the warehouse and connects to the indicator. The indicator dial is divided into four parts and can be found in one compartment as a reserve. You can connect the multivalve to appropriate electronic converters to make the LPG level visible in the driver’s seat. These converters provide information to the driver about the fuel level via analog or warning lights.
LPG Suction Process
Multivalve allows liquid LPG to be absorbed by a suction tube pointing towards the tank’s bottom. To ensure maximum fluid flow, the multivalve must have transition sections.
Cutting
Two valves are located on the multivalve that can block suction and filling pipe. They are usually in the open position, but can be closed during emergency situations or maintenance. These can be switched off. An electronic control system allows you to quickly close the suction pipeline when it is difficult to access the multivalve.
Current
The “overflow valve” placed inside the multivalve and on the LPG suction pipe serves to stop the flow when a certain calibration value is exceeded. The overcurrent valve prevents gas leakage when the LPG suction pipe connects to the engine has been damaged in an accident.
