Abstract

The invention provides an aseptic filling valve, which includes a valve body and a valve stem with a valve core. It is provided with a lever to drive the valve stem up and down. Extending into the valve body, the aseptic filling valve is also provided with a flexible diaphragm sleeved on the lever, and the flexible diaphragm is tightly matched with the lever and closes the valve body where the lever extends. The invention can realize the permanent aseptic barrier under the working condition of frequent switching for a long time, thereby improving the safety of aseptic filling production; moreover, with the difference of the distance from the fulcrum of the lever, the rotation range of the lever is different, so that the manufacturer has more advantages. There are many choices, and the aseptic partition implementation plan that is economical, reliable and easy to implement can be flexibly adopted according to the actual situation.

Description

Aseptic filling valve

Technical field

The present invention relates to a kind of aseptic filling valve.

Background technology

Present aseptic filling valve is CN2711133 such as publication number, and open day is the Chinese utility model patent in July 20 in 2005; Mostly adopt and straight up and down drive stem movement and the mode of switch filling valve; That is: drive valve rod mechanical mechanism and valve rod and dispose up and down, drive the axis of operation of valve rod mechanical mechanism and the up-down coaxial line of valve rod, like this; The up-down displacement that drives the valve rod mechanical mechanism is big; And need more greatly or the more complicated aseptic partition of area between the aseptic area and handle, not only difficult realized but also uneconomical, and hide some dangers for easily.

Summary of the invention

Technical matters to be solved by this invention provides a kind of aseptic filling valve, and it can make the mechanism and the obstruct between the aseptic area that drive stem movement become easier, thereby can improve the safety that sterile filling is produced.For this reason; The present invention adopts following structure: it comprises valve body and the valve rod that has spool; It is provided with and drives the lever that valve rod goes up and down, and said side of valve body has lever and stretches into mouth, and said lever stretches into valve body from the valve body side; Said aseptic filling valve also is provided with the flexible partition that is enclosed within on the lever, and said flexible partition and lever are sealed and matched and seal the valve body that lever stretches into the place.Owing to adopt technical scheme of the present invention; The present invention adopts the rotation of the lever that is in the side to drive valve rod, realizes the switch of valve, can make the valve arrangement that is in the aseptic area extremely simple; Simultaneously; The present invention is employed in the mode that barrier film is set between lever and the valve body and carries out aseptic partition, because near the lever rotation amplitude the balance pivot is minimum, compares with traditional mode straight up and down; More can realize the permanent aseptic obstruct under the long-time frequent switch operating mode, thereby can improve the safety that sterile filling is produced; And along with the difference apart from the balance pivot distance, the rotation amplitude of lever is different, makes producer that more choice arranged, and adopts flexibly according to actual conditions to have economy, reliability aseptic partition embodiment high, that realize easily concurrently.

Description of drawings

Fig. 1 is a cutaway view of the present invention.

The specific embodiment

With reference to accompanying drawing.The present invention includes valve body 1, have the valve rod 2 of spool 20, drawing reference numeral 22 is the guide vane on the valve rod.

The valve body upper end connects the liquid storage container that needs filling liquid; Be convenient installation manufacturing, aseptic control and sterilization; Said valve body comprises the upper valve body and following valve body of split; Upper valve body and following valve body are installed on the support 100 respectively and seal, mounting screw can pass from upper valve body support and with the blind threaded connection of being connected of following valve body, to help aseptic control and sterilization.The lower end of following valve body is a valve nozzle 13, and spool 20 cooperates with valve nozzle 13, realizes the switch of filling valve.

The present invention is provided with and drives the lever that valve rod goes up and down, and lever comprises power arm 31 and resistance arm 32, and power arm 31 i.e. the lever segment in balance pivot left side in the drawings, the lever segment on balance pivot right side during resistance arm 32 is promptly schemed.

Said lever stretches into valve body from the valve body side; Side of valve body has holds the passage 14 that lever stretches into part; Passage 14 has lever and stretches into mouthfuls 13, said aseptic filling valve be provided be enclosed within the outer and closed channel 14 of lever flexible partition 4, said barrier film is sealed and matched with lever simultaneously.The position of said diaphragm case on lever, the closer to balance pivot, when lever rotated, its deflection was more little, and simultaneously, barrier film preferably is enclosed within outside the resistance arm, like this, can reduce the physical construction that is in the aseptic area.According to condition of different, following situation also can be selected to adopt: 1, resistance arm partly or entirely is in the valve body; Even 2 power arms 31, also have the part or all be arranged in the passage 14.Through suitable passage 14 and lever length is provided, above dual mode can both be realized.

In the present embodiment, power arm 31 is not in the passage 14.Have lever Connection Block 5 to be installed outside stretching into mouthful said, power arm is in the Connection Block 5, and the driver train of said lever is installed on the Connection Block and in Connection Block, is connected with the power arm 31 of lever.Said driver train 5 adopts cylinder 6 in the present embodiment, is connected with power arm 31 through ball and socket joint 61.

The present invention is provided with the oscillating bearing bearing 71 as balance pivot, and oscillating bearing bearing 71 is arranged on the said Connection Block 5, the outer oscillating bearing 72 that cooperates with oscillating bearing bearing 71 that is provided with of said lever.

The said lever resistance arm 32 outer support sleeves 34 that also are with barrier film; Support sleeve 34 is other near oscillating bearing 33; Said barrier film is adjacent to and outside support sleeve, is bowl-type; Its periphery is clipped between valve body and the Connection Block and is fixed and seals lever and stretch into mouthfuls 13, also is provided with the positioning step 33 of barrier film on the lever resistance arm 32.

Said valve rod has and is used for and lever bonded assembly slide opening 21, being in the slide opening slidably with valve rod bonded assembly coupling end 35 of said lever.

The arrow direction is the liquid feedstock direction among the figure.Drawing reference numeral 200 is for needing the container of can.
