Problems solved by technology
[0002] At present, there are mainly two types of quantitative filling machines used in the field of liquid filling. One is the measuring cup mechanical valve filling machine, which mechanically controls the liquid level of the measuring cup to achieve quantitative filling; the other is Quantitative filling is achieved by controlling the liquid level difference between the upper and lower sides of the measuring cup with a liquid level sensor. Both models are filled with a fixed volume, which requires a measuring cup with accurate dimensions, which brings difficulties to the processing; and the capacity varies with temperature. The change cannot be eliminated, which also affects the filling accuracy; the filling valve cannot realize automatic cycle cleaning

Embodiment Construction
[0028] Examples such as figure 1 As shown, a liquid weighing filling valve includes a turntable 1, on which a liftable tray 51 is installed, a liquid cylinder 47 is installed above the tray 51, and a liquid connected to the liquid cylinder 47 is installed on the tray 51. As for the filling device, a flushing device that can cooperate with the liquid filling device is installed under the tray 51 .
[0029] The liquid filling device includes a valve cylinder 28, the upper end of the valve cylinder 28 is sealingly connected with a valve head 32 communicating with the liquid cylinder 47, the lower end is sealingly connected with a valve body 26, and the lower end of the valve body 26 is sealingly connected with an orifice 24, the lower end of the orifice 24 is equipped with a valve nozzle 16. A damping net 15 , a spacer 17 and a retaining ring 18 are installed in the valve mouth 16 .
[0030] A flushing interface 2 is installed on the flow port 24 , and the lower end surface of ...

A disclosed liquid weighing loading valve comprises a rotation table and a liftable pallet installed on the rotation table; a hydraulic cylinder is installed above the pallet; a liquid loading device communicated with the hydraulic cylinder is installed on the pallet; and a flushing device capable of making cooperative motion with the liquid loading device is installed below the pallet. By employing the above technical scheme, a liquid can be directly weighed and the loading precision is high and is not influenced by temperature variation; variable-velocity loading is realized, and when loading is coming to an end, the velocity changes from fast to slow, a liquid column injected into a bottle is mild, liquid choking and overflow cannot happen; automatic circulation cleaning is realized, cleaning is thorough, the valve is clean, no dead corners are left and sanitary requirements are satisfied; and the liquid weighing loading valve is reliable in safe protection.
Description
technical field [0001] The invention relates to a liquid weighing filling valve for injecting liquid into bottles, cups, barrels and other sub-packaging containers, belonging to the technical field of liquid filling.
