Intelligent control filling valve

Abstract

The invention discloses an intelligent control filling valve which comprises a close cup. A filling nozzle is mounted at the lower end of the cup, a spool used for controlling filling flow of the nozzle is mounted in the cup, the upper end of the spool is connected with a control device used for controlling movement of the spool, and precision of filling flow based on time control is improved greatly. Since liquid level difference is under control to the utmost extent and influences caused by interference factors such as switch valves and flow passages are also controlled, the problem of poor precision of filling flow based on time control in the prior art is solved completely and splashing during switch off of the filling valve is reduced.

Description

technical field [0001] The invention relates to a filling valve, in particular to an occasion suitable for liquid hot filling. It can be used for the filling of liquor and condiments, and it can also be used as an intelligent control filling valve for filling non-gas liquids such as rice wine, beverages, and liquid medicines. Background technique [0002] The filling valve is one of the main components of the filling machine. It is required that the filling valve can be opened and closed freely, the filling process is smooth and smooth, the filling level is accurate and consistent, and the filling level can be adjusted conveniently; the liquid is required to be sterilized at high temperature. There is no contact between the filling bottle mouth and no overflow of the filling liquid; the residual liquid in the filling valve is required to be easy to clean and empty, so as to avoid the mixing of the filling liquid and the residual liquid in the filling valve to produce odor, s...

Problems solved by technology

[0008] Solution 1: The liquid level in the wine vat is stabilized by the filling valve stabilization cup and the wine supply stabilization cover, but it still cannot achieve a certain accuracy

The reason is that when filling multiple bottles, the amount of wine consumed in filling is different, and the speed of filling wine in the wine inlet pipe is different, which will inevitably cause fluctuations and impacts of the liquid level in the wine tank;

[0009] Another reason is that while filling, the wine in the wine tank is also replenished into the liquid stabilization cup. During this period, although the liquid level is stable, the flow of the liquid is driven by a pressure difference. A funnel negative pressure area is formed above, and the negative pressure area of ​​the valve and the valve interferes with each other, resulting in more complex instability

The negative pressure area directly affects the flow rate. If the flow rate is unstable, the filling volume will not be accurate even if the time control is accurate.

[0010] Solution 2: Although in this case, the wine tank is disconnected from the quantitative cup during filling, which eliminates the influence of the valve and the valve, and also eliminates the influence of the fluctuation of the liquid level in the tank, but the disadvantage is that two cylinders are required, and the electrical control is complicated. , and the pipeline is long, the response time is long, and the cost is high

[0011] Plan 3: Although this case has been simplified and improved in terms of electrical control and structure, the first disadvantage is that when the valve is closed at the end of filling, the connecting rod moves down, causing splashing of wine at the filling port, and the filling is caused by the splashing of wine. Inaccurate installation and noise due to impact;

[0012] The second is that when the valve is opened, the wine tank is required to be disconnected from the quantitative cup, but in fact, if the chrome-plated valve core is used to cooperate with the quantitative cup to disconnect, because there is a gap, it cannot be completely disconnected, which will cause quantitative Quantitative deviation of the liquid in the cup, resulting in inaccurate filling volume

And if the seal is moved up to disconnect, but because the valve is opened and filled at the same time, it will interfere with each other, and the filling volume will still be inaccurate.

[0013] Other filling valves that control the filling volume by quantitative or weight or vacuum (not by time), such as electronic quantitative filling valves with magnetic rulers (magnetic displacement sensors) in the quantitative cups, and scales Heavy filling valve, complicated structure and high cost

Negative pressure equipotential filling valves require a cushion to seal the bottle mouth during filling, which may contaminate the bottle mouth, and the bottle holder needs to move up and down along the track, resulting in relatively high cost and energy consumption
