Production standards: GB 27790-2020 City Gas Pressure Regulators.
The pressure regulator is a direct-acting type, and the main pressure regulator is a soft-sealed closing form of the lever force transmission system. It can be repaired and maintained online. The product is easy to manage and replace.
It has few accessories and reliable operation, saving maintenance man-hours and costs. The voltage stabilization accuracy is AC10/15, and the closing accuracy reaches SG20,The cut-off valve adopts the fourth generation cut-off mechanism; this mechanism is in the form of steel ball brake release.
The main design is that the cutting film and the sliding mechanism are split. The sliding mechanism places the steel balls into the locking groove of the trip valve stem. When the sliding mechanism Under the thrust of the film, the locking sleeve generates a displacement that causes the steel ball to escape from the tight groove of the valve stem.
The valve stem is driven by the cut-off spring to complete the cut-off overpressure release function. This structure combines high response sensitivity and the most reasonable overall design structure to cut off the total process.
