Definitions

  • the present invention relates to a nozzle assembly for a sprinkler, especially to a nozzle assembly for a sprinkler that can provide on-off control of water and regulate the amount of water output.
  • a nozzle assembly for conventional underground sprinklers is revealed.
  • Refer to US Pat. No. 5086977 "SPRINKLER DEVICE”, underground sprinklers in which water pressure causes a pop-up riser means being moved to its extend or retracted position are disclosed.
  • a nozzle assembly is mounted in an axially movable nozzle housing assembly that is received in a cylindrical housing.
  • An opening is formed in the outer surface of the nozzle housing and a nozzle is inserted through the opening into the nozzle housing assembly.
  • the top of a cylindrical member of the riser means has an adjusting slot for setting the desired oscillating angle for the sprinkler. After water flowing through, the nozzle assembly is popped up slowly to a preset position and then water is ejected from the nozzle.
  • the amount of water output though the above nozzle assembly is unable to be adjusted.
  • the water flow ejected out from the nozzle assembly is delivered to a certain range.
  • the water flow is unable to be modified according to terrain and users' requirements.
  • a nozzle assembly with adjustable water output has been developed and invented based on the structure of the above underground sprinklers.
  • a pivotable arc valve body is arranged on a vertical water channel, located in a riser just below the nozzle.
  • the arc valve is pivotable between two positions by manually turning a drive member with a hand tool. When the valve body pivots to its first (vertical) position, the water flow path is substantially open while the valve body substantially obstructs the water flow path when it pivots to a second (horizontal) position.
  • a nozzle assembly For non-underground sprinklers a nozzle assembly is known from US 2,873,083 , wherein a water flow through a flow channel is controlled with a rod with a conical head by moving the rod via a threaded structure engaged with a threaded plug, which in turn is threaded into the main body of the nozzle assembly. While the structure allows controlling the flow it is unsuitable for underground sprinklers due to plug and rod extending from the main body. From US 4,184,239 a similar design is known.
  • a nozzle assembly is known wherein a water flow through the flow channel is controlled by the conical end of externally threaded valve members threaded into internally threaded holes. While this is suitable for underground sprinklers the valve members are directly thread into the holes from the outside and therefore the sealing is not very good and the valve members can be removed from the nozzle and be lost. From US 2006/0011742 A1 a similar design is known.
  • a nozzle assembly of a sprinkler according to claim 1 is disposed on a top of an inner tube of a sprinkler.
  • a vertical main channel is arranged along an axis of the nozzle assembly.
  • a water inlet connected with a water source for water supply is arranged at the bottom of the main channel while a water outlet is set on one side of the other end of the main channel.
  • An adjustment member for control of water flow is disposed on the main channel, located between the water inlet and the water outlet.
  • a side hole set on the main channel is connected with a ring while an inner threaded section is arranged near an outer end of an inner bore of the ring.
  • the adjustment member is a cylinder in which one end is a conical frustum having maximum outside diameter larger than the outside diameter of the cylinder and the other end is a slot.
  • the conical frustum is for closing the water outlet while the slot is used to assemble with driving devices.
  • An outer threaded section and a ring groove are respectively arranged on a surface of one end of the adjustment member having the slot. The outer threaded section is threaded with the inner threaded section of the ring while the ring groove is for receiving a sealing ring whose outer part is closely attached to the inner bore of the ring.
  • the diameter of a flow path opened from the main channel to the water outlet is controlled by the displacement of the adjustment member so as to regulate output water flow.
  • a nozzle assembly 10 for a sprinkler is connected on a top of an inner tube 101 of a sprinkler 100 shown in Fig. 6 and Fig. 7 .
  • the above mentioned inner tube 101 is mounted in an outer tube 102 of the sprinkler 100.
  • the inner tube 101 is moved up and down automatically by water pressure. After water being turned off, the inner tube 101 is retracted into the outer tube 102.
  • a water outlet 112 arranged at one side of the nozzle assembly 10 on top of the inner tube 101 is also hidden inside the outer tube 102, not exposed.
  • the connection between the sprinkler 100 and the nozzle assembly 10 is similar to that in prior arts.
  • the nozzle assembly 10 of the present invention features on that: a vertical main channel 11 is disposed along an axis of the nozzle assembly 10.
  • a water inlet 111 connected with a water source for water supply is arranged at the bottom of the main channel 11 while the water outlet 112 is disposed on one side of the other end of the main channel 11.
  • a nozzle 20 is disposed on a front end of the water outlet 112.
  • An adjustment member 30 that controls water flow is arranged at the main channel 11, between the water inlet 111 and the water outlet 112.
  • the water outlet 112 is closed or opened by displacement of the adjustment member 30.
  • the flow path diameter opened is also controlled by the adjustment member 30.
  • connection between the nozzle assembly 10 and the adjustment member 30 is as following.
  • a side hole 12 is disposed on the main channel 11 of the nozzle assembly 10 and is connected with a ring 13.
  • An inner threaded section 132 is set near an outer end of an inner bore 131 of the ring 13.
  • the ring 13 is integrated with the side hole 12 by high frequency induction heating.
  • the adjustment member 30 is a cylinder in which one end is a conical frustum 31 whose maximum outside diameter is larger than the outside diameter of the cylinder while the other end is a slot 32.
  • the conical frustum 31 is used to close the water outlet 112 while the slot 32 is for mounting driving devices (not shown in the figures).
  • An outer threaded section 33 and a ring groove 34 are respectively arranged around the surface of one end of the adjustment member 30 with the slot 32.
  • the outer threaded section 33 is threaded with the inner threaded section 132 of the ring 13.
  • a sealing ring 341 is mounted in the ring groove 34 and an outer part of the sealing ring 341 is closely attached to the inner bore 131 of the ring 13.
  • the ring 13 is connected to the side hole 12 on the main channel 11 of the nozzle assembly 10. Then the adjustment member 30 is threaded into the ring 13 and the conical frustum 31 whose maximum outside diameter is larger than the outside diameter of the adjustment member 30 is arranged at one end of the adjustment member 30. Thus a side end surface 311 of the conical frustum 31 beside the adjustment member 30 is against an inside end surface 133 of the ring 13 correspondingly. Thereby the adjustment member 30 will not be released from the ring 13 during the displacement process.
  • FIG. 8 another embodiment of a nozzle assembly not covered by the present invention is revealed.
  • An inner threaded hole 121 is disposed near an outer end of the side hole 12.
  • the adjustment member 30 with the outer threaded section 33 can be threaded with the inner threaded hole 121 directly.
  • a curved surface 35 is arranged at one end of the adjustment member 30 that faces the water outlet 112 for closing the water outlet 112. Thereby the output water flow can also be adjusted and controlled.
  • a further embodiment is disclosed.
  • the difference between this embodiment and above is in that: the structure of the nozzle assembly 10 is assembled with the adjustment member 30. That means differences in designs of parts for connection in an upper open end of the nozzle assembly 10.
  • the direction of displacement of the adjustment member and the direction of the water flow in the main channel of the nozzle assembly are crossed.
  • the directions are perpendicular to each other. Or there is a certain angle between the two directions.
  • the adjustment member is connected and assembled around the nozzle assembly. Thereby after the nozzle assembly being hidden in the outer tube of the sprinkler, the outlet water flow is unable to be changed by others purposely.
