Salvage-free adjustable water nozzle

The utility model discloses a salvage-free adjustable water nozzle which is designed for solving the problems that the traditional water nozzle has the defects of poor sealing effect, large leakage amount, discontinuous flow regulation and the like, and mainly comprises a regulation rod, a rotation block, a joint, a screw rod, a piston rod and a conical surface plunger which are sequentially connected and rotated, a protective sleeve, upper and lower connection cylinders, a lower nozzle cap and an upper nozzle cap with radial trilateral water holes, which are used for supporting a whole rotating mechanism and sequentially connected, a spring protecting sleeve for supporting each spring, a screw rod jacket, a spring base and the like. Along with the up-and-down reciprocating of the conical surface plunger, the opening sizes of the trilateral water holes of the upper nozzle cap present a gradual change process, so that the continuous regulation of the water nozzle flow can be realized by regulating the opening areas of the water holes; the contact surface between the conical surface plunger and the tail end of the sleeve is in conical surface valve base cooperation, so that the sliding wear is reduced; when the regulating valve is completely closed, the plunger conical surface and the valve body surface are sealed, and the sealing effect is better when the pressure is larger; and at the same time, the salvage-free adjustable type water nozzle can realize reverse movement, so that the flow regulation is realized by regulating the flow area.
