16 the natural gas pressure reducing valve of Jetta gas-oil dual-purpose taxi is always broken, mainly due to internal leakage. It won't take long to replace it. Is it caused by other reasons?

The operation of the pressure reducing valve is controlled by the pressure behind the valve. When the pressure sensor detects that the valve pressure indicates an increase, the valve opening of the pressure reducing valve decreases; When the pressure drop after the pressure reducing valve is detected, the valve opening of the pressure reducing valve is increased to meet the control requirements. The pressure reduction ratio of steam pressure reducing valve must be higher than the system value to a certain extent; It should be able to respond to positive or negative control signals even at maximum or minimum flow. These valves should be selected according to the useful control range, that is, 20% to 80% of the maximum flow. Normal is proportional or has proportional characteristics. These types of valves have the best flow characteristics and flow range required for proportional control. Generally, this valve should be installed horizontally in the pipeline.
