Detailed implementation mode

[0023] In order to further understand the content, characteristics and efficacy of the present utility model, the following embodiments are cited and detailed as follows in conjunction with the accompanying drawings.

[0024] As Figures 1 to 6 shown, a liquid filling mechanism for a pilot solenoid valve provided by an embodiment of the present utility model includes a base 1. The base 1 is rectangular and made of stainless steel material. The main function of the base 1 is to support the entire device. An operating platform is also provided on the base 1 for controlling the operation of the entire device.

[0025] A support column 2 is fixedly connected to the base 1. The support column 2 is movably connected with a support platform 3. A slideway is opened on one side of the support column 2. The support platform 3 is slidably connected in the slideway. A threaded rod 10 is rotatably connected in the slideway. The threaded rod 10 penetrates through the support platform 3. One end of the threaded rod 10 is fixedly connected with an adjustment knob 11.

[0026] Rotating the adjustment knob 11 will drive the threaded rod 10 to rotate. After the threaded rod 10 rotates, the support platform 3 will slide in the slideway of the support column 2, thereby adjusting the position of the filling assembly 5.

[0027] An adjustment plate 4 is movably connected to the support platform 3. A hole is opened in the middle of the support platform 3. The adjustment plate 4 is arranged in the hole. A hydraulic rod 12 is fixedly connected in the support platform 3. The adjustment plate 4 is fixedly connected to the movable end of the hydraulic rod 12.

[0028] The hydraulic rod 12 is used to drive the adjustment plate 4 to move. When the hydraulic rod 12 contracts, the adjustment plate 4 moves, thereby driving the filling assembly 5 to move, facilitating the placement and removal of the coil assembly.

[0029] One end of the adjustment plate 4 is fixedly connected with a filling assembly 5. The filling assembly 5 includes a liquid filling valve 501. A through hole is opened at one end of the adjustment plate 4. The liquid filling valve 501 is fixedly connected to the inner wall of the through hole. An infusion tube 8 is fixedly connected to one side of the liquid filling valve 501. A liquid pumping pump 502 is fixedly connected to the upper end of the liquid filling valve 501.

[0030] The liquid filling valve 501 is used to control the flow and cut-off of the liquid to ensure the liquid flow rate during filling. The liquid extraction pump 502 fixed at the upper end of the liquid filling valve 501 is used to extract the sealing liquid, that is, the sealing liquid is extracted from the liquid storage barrel 7 into the liquid filling valve 501 through the liquid delivery pipe 8.

[0031] A support 6 is fixedly connected to the upper end of the base 1, and a liquid storage barrel 7 is fixedly connected to the support 6. The liquid storage barrel 7 is funnel-shaped and made of stainless steel. The main function of the liquid storage barrel 7 is to store the sealing liquid.

[0032] The lower end of the liquid storage barrel 7 is communicated with a liquid delivery pipe 8. The liquid delivery pipe 8 is fixedly connected to the filling assembly 5. A groove is provided at the upper end of the base 1, and a vibration assembly 9 is arranged in the groove. The vibration assembly 9 includes a vibrator 901. The vibrator 901 is fixedly connected to the inner wall of the groove of the base 1. A fixed platform 902 is fixedly connected to the upper end of the vibrator 901. A buffer column 903 is fixedly connected to the inner wall of the groove of the base 1. The upper end of the buffer column 903 is open, and a first spring 904 is fixedly connected to the inner wall of the buffer column 903. The first spring 904 is fixedly connected to the bottom end of the fixed platform 902.

[0033] After the sealing liquid is poured into the coil assembly, the vibrator 901 is started, causing the fixed platform 902 to vibrate, thereby causing the coil assembly on the fixed platform 902 to vibrate, making the sealing liquid evenly distributed in the coil assembly and avoiding voids inside after solidification.

[0034] A fixing groove is provided at the upper end of the fixed platform 902. A placing groove is provided on the inner wall of the fixing groove. A second spring 13 is fixedly connected to the inner wall of the placing groove. The second spring 13 is fixedly connected to a fixing block 14. When the coil assembly is placed in the placing groove, the fixing block 14 will fix the coil assembly due to the elastic force of the second spring 13.

[0035] The working principle of the present utility model is as follows:

[0036] When the present utility model fills the coil assembly with the sealing liquid, first fix the coil assembly in the placing groove, then extract the sealing liquid from the liquid storage barrel 7 through the liquid extraction pump 502, and then pour the sealing liquid into the coil assembly through the liquid filling valve 501. After the filling is completed, start the vibrator 901 to vibrate to make the sealing liquid in the coil assembly evenly distributed. Then take out the coil assembly and wait for the sealing liquid to solidify to carry out the subsequent solenoid valve assembly.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
