Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings of the specification.

[0033] A sterile sampling integrated valve, which is composed of a valve body 1 and two valve cores. The valve body 1 is a valve cavity composed of multiple passages, a tank body outlet 7 and a two-way steam interface 3 , Three-way sampling port 6, the two spools are composed of A spool 2 and B spool 5. The A spool 2 is a spool valve type main spool, the B spool 5 is a sampling port spool, and the A spool 2 moves in three positions: left position, middle position, and right position. The valve spool controls the valve ports on the valve body 1 to be disconnected. When the A spool 2 is moved to the left position, the inlet ring groove set on the A spool 2 conducts the steam interface 3 and the valve cavity passage. At this time, the valve cavity and the tank Body discharge port 7 is blocked, open sampling valve 5 to perform pre-sampling sterilization,...

Abstract

The invention relates to a sterilizing and sampling integrated valve. The sterilizing and sampling integrated valve is characterized by being composed of a valve body and two valve cores, the valve body is composed of a valve cavity formed by multiple passages, a one-way tank discharging port, a two-way steam port and a three-way sampling port, the valve cores include a valve core A and a valve core B, the valve core A is a slide-valve-type main valve core, the valve core B is a sampling port valve core, and the valve core A is provided with three moving positions including a left position, a middle position and a right position. By the sterilizing and sampling integrated valve, control on the sterilizing and sampling process of a conventional bioreactor fermentation tank is simplified; various valves are integrated into a valve and can be controlled in a centralized manner.

Description

Technical field [0001] The invention belongs to the field of bioreactor fermentation tanks, and particularly relates to a sterilization sampling integrated valve. Background technique [0002] In the fermentation process of various fermentation tanks (mechanical stirring type, air lift type, strong magnetic type), it is necessary to check the fermentation status in the tank on-line, take samples and evaluate the microbial culture condition in order to determine the various control parameters in the tank (PH , DO, etc.) adjustment. Therefore, the accuracy of sampling is particularly important. The common practice in the industry is to disinfect and sterilize the sampling path through the cooperation of multiple valves, and then take samples. Although a qualified sample solution can be obtained by doing this, it has the following disadvantages: [0003] 1. It is easy to operate by mistake and is restricted by the professional level of the operators; [0004] 2. The time and quality ...
