Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, an embodiment of the present utility model is provided: the sagging type sprinkler with good sealing performance comprises a sprinkler body 1, a lower valve body 2 and a nozzle 3, wherein an external thread butt joint 101 is arranged at the top end of the sprinkler body 1, and a worker takes out the sagging type sprinkler, so that the sprinkler is connected to the end part of a water spraying pipe in a sprinkler irrigation system through the external thread butt joint 101;

a connector 4 is arranged on the outer wall of one side of the spray head body 1 in a threaded sealing manner, and a rotation control structure for controlling the conductivity of the spray head body 1 is arranged in the connector 4;

the lower valve body 2 and the spray head body 1 are internally provided with a conical cavity 201 communicated with the spray nozzle 3, the rotation control structure comprises a short shaft 401 rotatably arranged in the connector 4, one end of the short shaft 401 extends to the inside of the spray head body 1, one end of the short shaft 401 is fixedly provided with a long shaft 402, two sides of the surface of the long shaft 402 are symmetrically fixedly provided with valve plates 403, the long shaft 402 and the valve plates 403 are made of alloy steel members, and the long shaft 402 and the valve plates 403 made of alloy steel are high in density and heavy in weight, so that the rotation stability of the long shaft 402 and the valve plates 403 can be ensured;

the short shaft 401 can be manually rotated in advance by a worker, so that the short shaft 401 drives the long shaft 402 and the valve plate 403 to rotate, the valve plate 403 is utilized to control the conductivity of the spray head body 1, and when the valve plate 403 is in a parallel state, the conductivity of the spray head body 1 is the lowest, so that the liquid outlet pressure of the spray head is controlled;

an inner column 5 is fixed at one end inside the conical cavity 201, a valve core 6 is arranged on the inner thread of the inner column 5, an inner thread head 7 is arranged on the inner thread of the valve core 6, through holes 601 through which a water supply source passes are formed in two sides inside the valve core 6, a valve rod 8 is slidably arranged at the inner center position of the valve core 6, and a valve body unidirectional sealing structure is arranged between the valve rod 8 and the valve core 6;

the water source in the spray irrigation system is flushed into the conical cavity 201 through the external thread butt joint 101, and in the process, the conical cavity 201 can increase the flow rate of the water source due to the fact that the pressure of the water source is high, namely, the whole spray head is in a conducting state, so that the spray irrigation system works normally;

the one-way sealing structure of the valve body comprises a ring cover 9 fixed at one end of the surface of a valve rod 8, two sides of the top end of the ring cover 9 are provided with ejector rods 901 corresponding to the positions of the through holes 601, the top ends of the ejector rods 901 extend to the inside of the through holes 601, the outer diameter of the ejector rods 901 is equal to the inner diameter of the through holes 601, a reset spring 10 is fixed at the bottom end of a valve core 6, the bottom end of the reset spring 10 is fixedly connected with the bottom of the ring cover 9, one end of the surface of the valve rod 8 is fixedly provided with a baffle 801, and the upper surface of the baffle 801 is in contact with the lower surface of the ring cover 9;

when the switch valve controlling the group of spray pipes and the spray heads is in a fault state, part of water source enters the spray head body 1. At this time, because the water source pressure is lower, the water source is insufficient to overcome the elasticity of the reset spring 10, and the ejector rod 901 is always abutted in the through hole 601, namely the valve core 6 is in a closed state, so that the water source is prevented from leaking from the nozzle 3.

When the embodiment of the application is used, firstly, the worker takes out the sagging sprinkler head, make the sprinkler head be connected to the sprinkler pipe tip in the sprinkler irrigation system through external screw thread butt joint 101, when the ooff valve of this sprinkler pipe of control is in normally open state, the water source in the sprinkler irrigation system is surging into toper chamber 201 department through external screw thread butt joint 101, this in-process is because water source pressure is great, then water source passes through hole 601 department impact ejector pin 901, then the water source forces ejector pin 901 to withdraw from to the outside of through hole 601, and reset spring 10 is tensile state, the velocity of flow of water source through hole 601, toper chamber 201 and nozzle 3 blowout promptly, the whole sprinkler head is in the state of switching on promptly, make the system work normally, when the ooff valve of this group of sprinkler pipes of control, the shower head is in fault state, partial water source enters into in the sprinkler head body 1. At this time, because the water source pressure is lower, then the water source is insufficient to overcome reset spring 10's elasticity, then ejector pin 901 is in the through-hole 601 all the time, and case 6 is in the closed state promptly, and then avoids the water source to spill from nozzle 3 departments to through the effect of the one-way seal structure of valve body, improve the sealing performance of shower nozzle when the oozing valve breaks down, reduce the leakage quantity of water source, reduce sprinkler irrigation system's water wasting of resources and use cost.
