Plunger type sealing anti-theft sampling valve

Abstract

The invention discloses a plunger type sealing anti-theft sampling valve which comprises a valve body, a valve clack, a valve rod and an operation mechanism, wherein the valve body is provided with aliquid inlet, a steam inlet and a sampling outlet; the liquid inlet is arranged on the front part of the valve body; the inner side of the valve body, opposite to the liquid inlet, is provided with aflow cavity, and the front end of the flow cavity is provided with a valve seat; the head part of the valve clack is of a T shape, and the head of the valve clack can be slidably arranged in the flowcavity; the tail part of the valve clack is in slidable sealing fit with the valve body so as to form the on-off fits of the valve clack and the valve seat; the steam inlet and the sampling outlet arerespectively arranged on both sides of the valve body, opposite to the flow cavity; the front end of the valve clack is fixedly provided with a sealing valve pad which is matched with the valve seatin a sealing mode; and the head end of the valve rod is connected to the root part of the valve clack and is in coaxial linking fit with the valve clack. The invention has the advantages of good sealing property, sterilization, no dead angle, and the like.

Description

technical field [0001] The invention relates to a valve, in particular to a plunger-type sealed anti-theft sampling valve applicable to biological fermentation tanks or test tanks. Background technique [0002] Existing sampling valves applied to biological fermenters or test tanks include valves connected with fermentors or test tanks, steam valves connected with high-temperature steam for sterilization, and sampling valves for sampling. Many, poor sealing, and there are sterilization dead angles at each interface of the overall sampling valve, making the sampling valve susceptible to bacterial contamination, causing serious losses. In addition, the traditional sampling valve has no anti-theft function, making the fermentation tank or test The precious strains in the tank were stolen and lost. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a plunger-type sealed anti-th...
