Abstract
The present invention relates to a high pressure precision filling valve. The present invention comprises a valve core and a valve sleeve, wherein a valve nozzle sleeve is connected with the valve sleeve through a valve sleeve nut, the valve core arranged in a liquid cavity is adapted to a liquid outlet arranged on the valve nozzle sleeve, the valve core is connected with an electromagnetic solenoid arranged in the valve sleeve, and a pressure spring is assembled at the tail end of the electromagnetic solenoid. The present invention controls the balance between the current or the voltage of electromagnetic solenoid and the pressure spring so as to realize controlling the on-off and the opening degree of the filling valve, and control situations can be arbitrarily selected and set; the filling valve has the advantages of quick reaction, high filling speed, high filling precision, convenient control and satisfaction of high pressure filling requirements. The present invention is influenced by the fluctuation of filling pressure at a low degree. The present invention is assembled on a filling nozzle for application. The present invention is mainly applied to filling equipment of non-PVC film soft bag infusion solutions and can also be used in filling equipment of other liquid type products.
Description
Technical field
The present invention relates to a kind of accurate filling valve in high pressure, be mainly used on the filling apparatus of non-PVC film soft-bag large-infusion.
Background technique
The bulking system of transfusion similar drug, generally adopt a high position tank storage buffering liquid medicine, the pressure when stablizing liquid medicine filling, adopt programmable controller again, the switch of controlling pinch valve or pneumatic diaphragm valve according to the mobile time of can medicine reaches the purpose of controlling medicine can amount; This kind system high position tank need be placed on the height of 5-15 rice, and fluid pressure can only be controlled at below the 1bar, and single filling valve filling speed is extremely slow.Owing to influenced by filling pressure, when pressure transient or pressure were high, filling accuracy can be very low, because bulking system adopts many filling valves, each filling valve shut-in time is inconsistent, and the filling valve of closing earlier can cause the pressure surge of liquid in the can pipeline, has strengthened the error of other filling valve; If the employing pneumatic diaphragm valve because every pneumatic diaphragm valve is repeated inconsistent, is controlled break-make by pressurized gas simultaneously, the reaction time of pneumatic diaphragm valve is slow, thereby filling accuracy is subjected to certain restriction, can't improve again.
Summary of the invention
The object of the present invention is to provide a kind of accurate filling valve in high pressure, break-make and the control arbitrarily of aperture size, the filling accuracy height, control is convenient, satisfies the requirement of high-pressure filling.
High pressure precision filling valve of the present invention, comprise spool and valve pocket, the valve nozzle cover is connected on the valve pocket by the valve pocket nut, and the liquid outlet that spool in the liquid container and valve nozzle put adapts, its spool is connected on the interior o of valve pocket, and the end of o is fitted with stage clip.
According to electromagnetic principle, normal state o no electric circuit, spool is not subjected to electromagnetic force, and only under the effect of stage clip, spool is closed filling valve.When o was switched on, spool was issued to balance in the effect of electromagnetic force and stage clip, and filling valve is opened certain aperture, and o is made with different curtages, and filling valve can be opened different apertures, break-make and the control arbitrarily of aperture size.In the pouring process, can earlier filling valve be opened fully, filling valve is can fast under the high pressure effect; When filling liquid turns down appropriate location can at a slow speed with the filling valve aperture during near the can amount, when reaching the can amount, filling valve is closed fully.The filling accuracy height, control is convenient.
Among the present invention:
Equipped guide holder is established the end face bearing between spool and guide holder outside spool, guarantees the straight line motion of spool, improves the application performance of filling valve.
Front end at spool connects the guiding last item, and the liquid outlet that allows guiding last item and valve nozzle put adapts more reliable performance.
Between spool and valve pocket, establish sealing gasket and O-ring seals, strengthen sealability.
Equipped sealing valve nozzle on the liquid outlet of valve nozzle cover, the outside of sealing valve nozzle is provided with the can surface of contact, and the can surface of contact is provided with seal boss, is beneficial to the quick-sealing fill operations.
Correspondingly on valve pocket and valve pocket nut be provided with the liquid outlet opening that is connected with liquid container, in case filling liquid flows in the valve pocket by the sealing valve nozzle, liquid also can flow to the valve body outside from liquid outlet opening, prevents that the liquid that flows into from causing damage to the element of inside.
Accurate filling valve in high pressure of the present invention, by the curtage of control o and the balance between stage clip, realize the control of filling valve break-make and aperture size, the control situation can be selected arbitrarily and set, filling valve is swift in response, and filling speed is fast, be subjected to the filling pressure influence of fluctuations little, the filling accuracy height, control is convenient, has satisfied the requirement of high-pressure filling.Be fitted on the can mouth and use, be mainly used on the filling apparatus of non-PVC film soft-bag large-infusion, also can be used on the filling apparatus of other liquid kind product.
