Embodiment Construction
[0014] refer to figure 1 and figure 2 , a filling valve of the present invention, comprising a straight valve body 1 and a piston rod 2 movably installed in the valve body 1, the nozzle at the lower end of the valve body 1 is set as a filling port 11, and The valve body 1 is provided with an input hole 12, and there is a space between the valve body 1 and the piston rod 2 to communicate with the input hole 12 and the filling port 11. The plug 21 of the loading port 11, the inner wall of the filling port 11 corresponds to the outer wall of the plug 21, the top of the plug 21 is provided with a negative pressure vacuum anti-drip hole 211, and the piston rod 2 is provided with an anti-drip hole 211 that is compatible with the anti-drip hole. The hole 211 is connected to the ultra-vacuum hole.
[0015] As an improvement of the above embodiment, the plug 21 is screwed to the piston rod 2 , and the piston rod 2 is also screwed to an adjustment nut 22 that can be adjusted to abut ...

The invention discloses a filling valve. The filling valve comprises a valve pipe body and a piston rod movably installed in the valve pipe body; a pipe opening at the lower end of the valve pipe bodyis provided with a filling opening, an inlet hole is formed in the valve pipe body, and a space for communicating the inlet hole with the filling opening is reserved between the valve pipe body and the piston rod; and a plug capable of correspondingly blocking the filling opening is arranged at the lower end of the piston rod, and the inner wall of the filling opening corresponds to the outer side wall of the plug; and the plug is provided with a negative pressure vacuum anti-leakage hole, and a super-vacuum hole communicating with the anti-leakage hole is formed in the piston rod. Accordingto the filling valve, pressure impact is formed through symmetric structures of the piston rod and the filling opening, sudden flow is directly relieved, stability and oil non-splashing are kept in afilling working state, the filling valve is switched into a vacuum negative pressure state to keep anti-leakage after being closed, and the filling valve is suitable for a wide measuring range.
Description
technical field [0001] The invention relates to a filling valve. Background technique [0002] Conventional filling valves often have problems of oil splashing and dripping in the filling working state, especially the buffer drop type food-grade pneumatic valve, for the filling process of quantitative metering with different settings, the filling is not smooth, splashing Oil and dripping will significantly cause various inconveniences of filling, and filling valves need to be improved to solve these industry problems. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a filling valve capable of alleviating rapid flow and maintaining stable filling, and capable of closing the back vacuum to prevent dripping. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A filling valve, comprising a valve body and a piston rod that can be movably installed in the ...
