Specifically, the cleaning channel 122 is communicated with the gap between the valve core 11 and the valve core cavity 121, when positioning cleaning is needed, the lower end surface outlet part of the valve seat 12 is sealed, cleaning liquid can flow into the valve core cavity 121 from the cleaning channel 122 and flow out of the filling channel 112 from the throttling channel 111, so that the filling valve 1 is cleaned.
Illustratively, as shown in fig. 5, the throttle channel 111 includes a main flow channel 1112 and a diversion channel 1111, the cross-sectional area of the main flow channel 1112 is larger than the cross-sectional area of the diversion channel 1111, so that the liquid column flow of the main flow channel 1112 is larger than the liquid column flow of the diversion channel 1111, and the main flow channel 1112 and the throttle channel 111 are matched for use, so that the filling efficiency can be ensured, the filling liquid column can realize a plurality of diversion flows to ensure the uniformity and stability of the liquid column, and stable and smooth filling can be realized.
Specifically, in the present embodiment, the main flow channel 1112 is a circular hole, the center line of the main flow channel 1112 coincides with the axis of the valve element 11, the number of the shunt channels 1111 is plural, and the plurality of shunt channels 1111 are uniformly distributed along the circumferential direction of the main flow channel 1112. The center line of the main flow channel 1112 is coincident with the axis of the valve core 11, so that the liquid column with the largest flow is positioned in the middle of the valve core 11 of the filling valve 1, the filling efficiency is ensured, the liquid column is conveniently filled in the bottle body, and the liquid is prevented from leaking. The more the number of the diverting passages 1111 is, the better the diverting effect is in the limited cross-sectional area of the valve spool 11, but the preferred number of the present embodiment is 12 if considering various factors such as the difficulty of the processing process, the processing cost and the like.
As shown in fig. 6, in the present embodiment, the cross section of the diverting passage 1111 is trapezoidal, and the width of the diverting passage 1111 increases from inside to outside in the radial direction of the valve core 11, that is, the width of the diverting passage 1111 near the end of the main flow passage is smaller than the width of the diverting passage 1112 far from the end of the main flow passage, so that the flow rate of the liquid column flowing out of the diverting passage 1111 from the middle to the periphery of the valve core 11 is increased from small, the diverting effect is improved, and the smoothness of filling and the filling efficiency are ensured.
In other embodiments, the shape of the shunt channels 1111 may also be triangular, fan-shaped, etc.
In other embodiments, the shunt channels 1111 may also be round holes, diamond shaped, etc.
Preferably, as shown in fig. 7, in the present embodiment, the main flow channel 1112 is communicated with the shunt channel 1111, and the main flow channel 1112 is communicated with the shunt channel 1111, so that the stability of the filling liquid column can be ensured while the shunt effect is improved, the filling liquid column is collected into a single liquid column, so that the filling of the liquid column into the bottle body is facilitated, the liquid flow speed is improved, and the filling efficiency is ensured.
