Abstract
This patent relates to a liquid outlet diameter adjustable shower nozzle, its characteristic by: the sprayer comprises a sprayer body part, a sprayer joint part and the like, wherein two liquid outlet channels are formed in the sprayer body, a conical valve core is arranged in the sprayer body, a spring is arranged on the conical valve core, a straight rod of the conical valve core is connected with a piston, the piston is arranged in a piston cylinder in the sprayer body, a liquid inlet of the piston cylinder is connected with the liquid outlet channels, air holes are formed in the tail end of the piston cylinder, liquid medicine in the liquid outlet channels enters the piston cylinder through the liquid inlet of the piston cylinder, pressure acts on the piston, when the liquid pressure is high, the piston is pushed, the diameter of the liquid outlet is increased, when the liquid pressure is low, the elastic force of the spring is larger than the force of the liquid acting on the piston, and the diameter of the.
Description
Technical Field
The patent relates to a shower nozzle of liquid outlet diameter adjustable belongs to plant protection machinery technical field.
Background
China is a big agricultural country, the plantation area of various crops is large, the pesticide spraying amount is large every year, but plant protection machinery is relatively backward, most of modern nozzles are unsatisfactory in atomization effect, and the same atomization effect cannot be achieved under different pressures, so that the operation range is relatively fixed.
Disclosure of Invention
The purpose of this patent is to prior art not enough, provides a liquid outlet diameter adjustable shower nozzle, and this shower nozzle changes the liquid outlet diameter through adjusting the toper case, and then realizes realizing the same atomization effect under the liquid pressure of difference.
In order to achieve the purpose, the following technical scheme is adopted in the patent.
This patent relates to a liquid outlet diameter adjustable shower nozzle, its characteristic by: the sprayer comprises a sprayer body part, a sprayer joint part and the like, wherein the sprayer body part is provided with two liquid outlet channels, a conical valve core is arranged in the sprayer body, a spring is arranged on the conical valve core, a straight rod of the conical valve core is connected with a piston, the piston is arranged in a piston cylinder in the sprayer body, a liquid inlet of the piston cylinder is connected with the liquid outlet channels, the tail end of the piston cylinder is provided with an air vent, the sprayer joint part is provided with a liquid inlet hole, threads are processed on the surface of the sprayer joint part, and the sprayer body.
This patent is compared with the advantage of traditional shower nozzle.
1. The diameter of the liquid outlet can be adjusted according to the liquid pressure.
2. When no liquid exists in the liquid outlet channel or the pressure is zero, the conical valve core closes the liquid outlet channel opening under the action of the spring, so that foreign matters can be prevented from entering and blocking the spray head.
Drawings
Fig. 1 is a cross-sectional view of a spray head with an adjustable diameter of the liquid outlet.
In the figure 1, a conical valve core 1, a liquid outlet channel 2, a spray head body shell 3, a spring 4, a piston cylinder liquid inlet 5, a piston 6, a shaft end retainer 7, a piston cylinder 8, a connecting bolt 9, a set screw 10, a piston cylinder cover 11, a piston liquid inlet 12, a sealing washer 13 and an air vent 14 are arranged.
Detailed Description
The mechanism is further explained with reference to the attached drawings.
The patent shown in fig. 1 relates to a nozzle with an adjustable diameter of a liquid outlet, which is characterized in that: the sprayer body part and the sprayer joint part are composed, wherein the sprayer body is provided with two liquid outlet channels, a conical valve core is arranged in the sprayer body, a spring is arranged on the conical valve core, a certain pretightening force is generated when the spring is installed, the conical valve core is connected with a piston through a straight rod, the piston is arranged in a piston cylinder in the sprayer body, a liquid inlet of the piston cylinder is connected with the liquid outlet channels, the tail end of the piston cylinder is provided with an air vent, liquid medicine in the liquid outlet channels enters the piston cylinder through the liquid inlet of the piston cylinder, the rod end of the piston is pressurized by liquid, the pressure on the rod end of the piston is atmospheric pressure, when the liquid pressure is higher, the acting force on the piston is larger than the elastic force of the spring, the piston is pushed, the diameter of the liquid outlet is increased, when the liquid pressure is lower, the elastic force of the spring is, and then reach the atomizing effect of ideal, shower nozzle joint part passes through bolted connection with the shower nozzle body, and it has the inlet to open on shower nozzle joint part, and its surface machining has the screw thread, the installation of the shower nozzle of being convenient for.
