Method, controller, valve arrangement and portioning device for portioning a flowable, optionally pressurized mass

Номер: US20120132284A1
Автор: Leo Bühler
Принадлежит: Individual

A method is provided for portioning a flowable, optionally pressurized mass. In a first step a first pinch valve is opened and a second pinch valve located thereafter in a principal flow direction of the mass (m) is slightly closed. As soon as a desired quantity of the mass has passed the pinch valves the first pinch valve is closed. The second pinch valve is then opened. The opening, the slight closing and the closing of the first pinch valve and of the second pinch valve is accomplished by a pressure medium. A controller, a valve arrangement and a portioning device are also provided for executing the method.

The invention relates to a manual control part of a suction device with a valve, which manual control part can be adjoined downstream by a suction line and upstream by a pipette or pipette tip. The manual control part consists of a cylindrical, elastically deformable jacket, which defines a receiving space for a valve body, and of a valve body, which is received in the jacket and which defines, within the receiving space, a first space located in the upstream direction and a second space located in the downstream direction. In the valve body a flow connection between the first space and the second space is provided by at least one radially outwardly directed valve seat with a valve opening. The valve seat bears on the inner wall of the jacket, wherein the jacket can be compressed laterally of the valve seat in order to open the valve. In this way, the inner wall is moved away from the at least one valve seat.

The system utilizes one or more segments of unreinforced conduit that are encapsulated at various points along a length of the segment with one or more rigid encapsulating members. The unreinforced conduit may be made a disposable element while the rigid encapsulating members may be re-used. In one aspect, the encapsulating member may include a two-part valve body that surrounds and encapsulates a portion of the unreinforced conduit. In another aspect, the encapsulating member may include a two-part jacket that surrounds and encapsulates a portion of the unreinforced conduit. The two-part valve bodies and two-part jackets may be joined at various points within the system as part of the overall flow system.

The front plate may be transparent. The control valves operate by simply pressing on the tubing in the support channels to block flow, without invasion of the flow path. The tubing sets can be easily replaced, cleaned or sterilized. The invention is useful in a range of controlled-flow processes e.g. chromatography and filtration. 1.
