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...
