Embodiment Construction

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

[0033] An integrated valve for sterilization and sampling, 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 outlet 7, and a 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 type main spool, the B spool 5 is the sampling port spool, and the A spool 2 moves with three positions: the left position, the middle position and the right position. The spool controls the valve ports on the valve body 1. When the A spool 2 moves to the left position, the intake ring groove set on the A spool 2 conducts the steam port 3 and the valve cavity. At this time, the valve cavity and the tank If the body discharge port 7 is blocked, the sampling valve 5 can be opened to carry out sterilization, disinfection, and sewage discharge b...

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, in particular to an integrated valve for sterilization and sampling. Background technique [0002] During the fermentation process of various fermentation tanks (mechanical stirring type, air lift type, strong magnetic type), it is necessary to detect the fermentation state in the tank online, and take samples to test and evaluate the microbial culture status, so as 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 sterilize the sampling channel through the cooperative operation of multiple valves, and then take samples. Although qualified sample liquid can be obtained in this way, it has the following disadvantages: [0003] 1. It is easy to operate by mistake and is limited by the professional level of the operator; [0004] 2. The time and qu...
