Liquefied petroleum gas is colorless and odorless gas, liquefied petroleum gas proportion due to weight than air, so often gather in the indoor floor, sewage etc., if mixed with air reaches the explosion limit, meet fire combustion explosion occurs, thus leakage is very big hidden trouble, timely detection of leakage to prevent accidents is crucial. In daily use which required in the relief valve with Gas LPG pressure gauge, Gas LPG Pressure Gauge can not only indicates the liquefied gas storage capacity, but also can discover whether the leak.

Domestic liquefied petroleum gas leakage for angle valve seat sealing or stem seal damage; reducing valve angle valve connection is not tight or seal damage; rubber tube aging, cracking or too loose; cooker rotating core sealing, such as the causes have been excluded, may be the cylinder leakage. Gas LPG Pressure Gauge now plays a very important role.
