How can the Gas Tank safety valve be adjusted?
       Adjustment of the Gas Tank safety valve: 1. Adjust the setting pressure: Within the specified working pressure range, the adjustment pressure can be adjusted by changing the spring preload compression by rotating the adjusting screw. Remove the safety valve bonnet, the nut will be loose, first increase the inlet pressure, so that the valve flap once, if the set pressure is low, then press the clockwise rotation adjustment screw sets; if the set pressure is high, Rotate the screw sleeve counterclockwise. 2. Adjust the discharge pressure and return seat pressure: adjust the adjustment ring by adjusting. Unscrew the adjustment ring fixing screw, insert the thin wire from the exposed screw hole, you can dial the adjustment ring, when the adjustment ring to the right toggle, adjust the circle position, Gas Tank discharge pressure and back seat pressure will be reduced, the contrary It rises. Each adjustment should not be too large, usually within 5 teeth. In order to prevent accidents, before the adjustment of the adjustment ring, the inlet pressure should be properly reduced, the gas cut off.
The main role of the tank: to reduce the piston air compressor discharge of the air pulse to improve the continuity of the output air flow and pressure stability, further precipitation of compressed air in the water and oil, to ensure the continuous supply of sufficient gas. Cans can be used in parallel, can also be used with a single; Gas Tank is a pressure vessel, sentinel factory by the pressure vessel, each with a container inspection and safety valves, valves and pressure gauges and other accessories. Moisture - the relative humidity in the atmosphere is generally as high as 65% or more, after compression condensation, it becomes wet saturated air, and entrain a large number of
Liquid water droplets, which are the root cause of equipment, pipes and valves, can also block the small holes in the pneumatic system. It is worth noting that even if the pure saturated air is separated from the net, as the temperature decreases, there will still be condensed water.
About 10 ℃ lower, the saturated water content will drop 50%, that is, half of the water vapor into liquid water droplets (see Table 1). So in the compressed air system using multi-stage separation filter or the compressed air pretreatment with a certain relative humidity in the dry gas is very
Necessary; compressed air is the role of the separation of water tank, the middle of the air tank is imported, the upper part of the outlet, the lower part of the drainage hole, due to the air compressor outlet pressure is increasing, the air moisture affected by pressure , Humidity changes, water vapor into water. Simply put it simply, for reference only. Essence is a physical and chemical problems.
The main load of the Gas Tank is the internal gas pressure, the wind load and the seismic action. Wind pressure should be considered in wind load. The wind load factor of high pressure spherical tank is generally 0.30 ~ 0.35. The horizontal seismic action of the wet tank includes the seismic force generated by the tank and the weight of each tower, and the hydrodynamic pressure caused by the vibration of the water in the tank. The horizontal seismic action of the dry tank includes the seismic force generated by the weight of the cylinder and the weight of the piston. Calculate the snow load to consider the eccentric moment caused by the local accumulation of snow in the top of the tank.
In the production of low-pressure Gas Tank, the tank is divided into several parts in the processing plant prefabricated, and then the total installation site, which can reduce the site to install the weld. From the parts lofting, production, Gas Tank to the overall installation of all stages must be strictly checked to ensure the final overall accuracy. Install the dry tank tank, the first laying the bottom plate, in the bottom of the assembly of the piston, and in the piston above the top truss, laying roof. At the same time, the lower part of the tank and the column. And then to the piston below the blast to rise, the use of the piston as a construction platform to install the upper sections of the wall. Step up the piston, step by step to install the column and the wall, to be designed after the height of the tank top truss and the top of the column fixed, and then put down the piston, all installed to complete. Large volume of high pressure Gas Tank can be used to suppress the block shell, welded in the field. After welding, all welds are required for quality inspection.
