ABSTRACT:
A three member longitudinally slidable irrigation pipe gate for opening and closing an outlet port in a cylindrical irrigation pipe. The gate includes a base member slidingly abutting the inside wall surface of the irrigation pipe, a cover member slidingly abutting the outside wall surface of the pipe, and a U-shaped resilient spring disjointed from the base and cover members and securing them together to form an integral pipe gate structure. The spring is constructed from a resilient glass fiber filled acetal plastic to facilitate disassembly and repair of the pipe gate.
