Abstract
The utility model relates to a high pressure accurate filling valve which comprises a valve core and a valve housing. A valve nozzle housing is connected with the valve housing through a valve housing nut. The valve core in a liquid cavity is suit with a liquid outlet on the valve nozzle housing. The valve core is connected with an electromagnetic solenoid in the valve housing. The end of the electromagnetic solenoid is provided with pressed springs. The utility model controls the current or the voltage of the electromagnetic solenoid and the balance between the pressed springs, thereby realizing the make and break of the filling valve, the control of the opening size, and the controlling state of random selecting and setting. The filling valve with fast reaction, high filling speed, and little influence of the vibration of the filling pressure, high filling accuracy and convenient control fulfills the requirements of the high pressure filling. The utility model is arranged on the filling nozzle and applies to the non PVC film soft bag large scale liquid transporting filling devices and other liquid production filling devices.
Description
Technical field
The utility model relates to a kind of accurate filling valve in high pressure, is mainly used on the filling apparatus of non-PVC film soft-bag large-infusion.
Background technology
The bulking system of transfusion similar drug, generally adopt an elevated tank storage buffering liquid medicine, the pressure when stablizing liquid medicine filling, adopt Programmable Logic 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 elevated 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 is inconsistent, and the filling valve of closing earlier can cause the fluctuation of pressure 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 compressed 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 purpose of this utility model is to provide a kind of accurate filling valve in high pressure, break-make and the control arbitrarily of aperture size, and the filling accuracy height, control is convenient, satisfies the requirement of high-pressure filling.
Accurate filling valve in high pressure described in the utility model, 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 fluid chamber 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 condition o no power, 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.
In the utility model:
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 packing seal and O-ring seals, strengthen sealing property.
Equipped sealing valve nozzle on the liquid outlet of valve nozzle cover, the outside of sealing valve nozzle is provided with the can contact surface, and the can contact surface is provided with seal boss, is beneficial to the fast sealing fill operations.
Correspondence is provided with the fluid hole that is connected with fluid chamber on valve pocket and valve pocket nut, in case filling liquid flows in the valve pocket by the sealing valve nozzle, liquid also can flow to the valve body outside from fluid hole, prevents that the liquid that flows into from causing damage to the in-to-in element.
The utility model accurate filling valve in high pressure, 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 type product.
