Agricultural Irrigation UPVC Valves: Installation Methods and Advantages

I. Core Installation Methods (Taking Common Flange Connection and Socket Connection as Examples)

1. Pre-installation Preparation
   • Check if the valve model matches the pressure of the irrigation system (the common pressure rating for agricultural irrigation is 0.6-1.0MPa) and if the caliber is consistent with the pipeline.
   • Clean the pipeline interfaces and the valve sealing surfaces to remove impurities and burrs (which may affect sealing performance). Meanwhile, prepare special UPVC glue (for socket connection) or flange gaskets and bolts (for flange connection).
2. Pipeline Positioning and Cutting
   • Cut the UPVC pipeline according to the valve installation position. Ensure the cut is vertical and flat, and reserve the connection length at both ends of the valve (for socket connection, the depth of the pipeline inserted into the valve socket should be reserved, usually 1/2-2/3 of the socket length).
3. Connection and Installation
   • Socket Connection (for small and medium calibers, e.g., DN20-DN110): Evenly apply special UPVC glue to the insertion end of the pipeline and the inner side of the valve socket. Quickly insert the pipeline into the socket until it reaches the bottom, hold it in place for 10-15 seconds to fix, and let it stand for 24 hours until the glue cures before allowing water to pass through.
   • Flange Connection (for large calibers, e.g., DN125 and above): Align the valve flange with the pipeline flange, place a suitable rubber gasket (water-resistant and anti-aging type) in between, and tighten the bolts evenly in a diagonal order to avoid water leakage caused by uneven local stress.
4. Post-installation Inspection and Commissioning
   • After installation, manually open and close the valve to check if the operation is smooth without jamming.
   • Conduct a low-pressure water test (about 0.2MPa) to check sealing performance. Observe if there is water leakage at the interfaces, and put the valve into normal irrigation use only after confirming no issues.
