Problems solved by technology

[0002] The sampling valve traditionally used in the pharmaceutical industry and biological cell culture uses a threaded connection between the valve core and the valve body, resulting in dead angles at the connection part. During sampling, it is easy to cause cell fluid or liquid medium to remain in these dead angles, which not only affects sampling The valve is used normally, and it brings difficulties to the cleaning of the sampling valve

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings.

[0021] The reference signs are explained as follows:

[0022] 1——Sterile tube socket 2——Half gland

[0023] 3——Steam inlet pipe interface 4——Sampling valve body

[0024] 5——Adjusting nut 6——Clip spring for shaft

[0025] 7——sampling valve spool 9——spool cap

[0026] 8, 10, 14——O-ring 11——locating pin

[0027] 12——Pendant 13——Hexagon screw

[0028] Such as figure 1 , 2 As shown, the sanitary cell sampling valve is mainly composed of a sterile pipe connection seat 1, a sampling valve body 4 and other parts. The ones are distributed symmetrically on both sides of the sampling valve body, with an included angle of 128 degrees. The steam inlet pipe interface 3 is a one-way steam inlet device, with a built-in one-way valve or valve core, so that the steam will only enter and not return from this interface. To return, the pendant 12 is a fake...

Abstract

The invention discloses a sanitary cell sampling valve, which comprises a sterile tube connecting base and a sampling valve body; the lateral of the lower end of the sampling valve body is provided with an air inlet pipe interface and a pendant; the sampling valve body is internally provided with a sampling valve core; the valve core is provided with a sampling cavity capable of being communicated with an air inlet pipe; and the sampling valve is connected with a pipe through the air inlet pipe interface at the lower end of the valve body to carry out sterilization and cleaning without hygienic dead angles, is convenient and efficient, and can be used for the sampling of a cell culturing tank, the feed supplement of the fermentation and the liquor relief extract in the process of cell continuous culture.

Description

technical field [0001] The present invention relates to a cell culture sampling device, specifically a cell sampling valve. Background technique [0002] The traditional sampling valve used in the pharmaceutical industry and biological cell culture uses a threaded connection between the valve core and the valve body, resulting in dead angles at the connection part. When sampling, it is easy to cause cell fluid or liquid medium to remain in these dead angles, which not only affects sampling The normal use of the valve has brought difficulties to the cleaning of the sampling valve. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the present invention aims to provide a hygienic cell sampling valve that has no hygienic dead ends, is easy to clean, and is convenient and efficient to use. [0004] The technical scheme adopted in the present invention is: [0005] A sanitary-grade cell sampling valve, comprising a sterile pipe socket...
