Technical Field

[0001] The utility model relates to the technical field of filling valves, in particular to a filling valve with a damping net. Background Art

[0002] The filling valve is an important component used in filling machinery and equipment. It is mainly used to control the flow of liquid or gas and ensure accurate control of flow and filling volume during the filling process. The filling valve is usually composed of a valve body, a valve core, a seal, a transmission device, etc. Its design and working principle vary according to different filling requirements and liquid properties.

[0003] In the prior art, a filling valve with a damping net (Announcement No.: CN207313096U) is provided with a plurality of damping nets which are cross-stacked at the outlet end of the filling valve, so that the speed at which the liquid flows from the valve cavity into the container can be gradually slowed down, thereby buffering the filling flow rate of the liquid and making the liquid output softly in the form of a liquid column. The liquid is filtered by the damping of the damping net, which facilitates the elimination of bubbles in the liquid. However, when the device is used to fill liquids of different viscosities, it is necessary to replace the damping net with the corresponding aperture size, which is not convenient enough after a series of disassembly and assembly operations. Therefore, it is urgent to design a filling valve with a damping net which is more convenient to use. Utility Model Content

[0023] When in use, the second damping net 8 is rotated and sleeved on the surface of the first damping net 7, and the adjusting member 3 is rotated to drive the transmission shaft 4 to rotate. The transmission shaft 4 drives the second damping net 8 to rotate on the surface of the first damping net 7, thereby adjusting the flow aperture of the liquid, avoiding disassembly of the valve body 1 to replace the damping net, and improving the convenience of the filling valve during use.

[0024] In this embodiment, two limit grooves are symmetrically provided on the surface of the transmission shaft 4, the elastic limit assembly 10 includes two baffles 1001 and multiple reset springs 1002, the multiple reset springs 1002 are fixedly installed between the two baffles 1001, and the center of one side of the two baffles 1001 is provided with a circular hole that is compatible with the outer diameter of the transmission shaft 4, the adjusting member 3 includes a knob cover 301, an inner thread 303 is provided on the inner wall of one side of the knob cover 301, a protrusion 304 is provided on one side of the knob cover 301, and a limit hole 305 that is compatible with the transmission shaft 4 is provided on the adjusting member 3. The knob cover 301 is threadedly sleeved on one side of the valve body 1, and the arc surface of the knob cover 301 is circumferentially provided with multiple scale lines 302.

[0025] When in use, the second damping net 8 is inserted into the valve body 1 from one end of the second equipment cavity 102 and is sleeved on the surface of the first damping net 7. Then the elastic limiting assembly 10 is sleeved on the surface of the transmission shaft 4, and the baffle 1001 at one end thereof is pressed against one end of the second damping net 8. Then the adjusting member 3 is slidably sleeved on the surface of the transmission shaft 4, and the knob cover 301 is turned to be threadedly connected to one side of the valve body 1 until the protrusion 304 is pressed against the baffle 1001 at the other end of the elastic limiting assembly 10 and the reset spring 1002 is compressed, thereby limiting the second damping net 8 and making the disassembly and assembly of the second damping net 8 more convenient.

[0026] In this embodiment, a micro hot air blower 5 is fixedly installed in the first equipment cavity 101, an air hole is opened on one side of the first damping net 7, a one-way valve 6 is fixedly installed in the air hole, the air outlet of the micro hot air blower 5 is connected through the air pipe one-way valve 6, and a dust cover 2 is detachably installed near the outlet of the first equipment cavity 101.
