Description

Three-way valve for sampling Technical Field The utility model relates to the technical field of three-way valves, in particular to a three-way valve for sampling. Background The three-way valve is a fluid control device with three interfaces, and controls fluid to flow from one interface to any one of the other two interfaces or to flow to the two interfaces at the same time by changing the position of an internal valve core, so that on-off or flow direction switching of the fluid among the three interfaces is realized. The traditional three-way valve generally does not have a sampling opening, is difficult to sample fluid in the three-way valve body, is relatively complicated to operate, is low in efficiency and inconvenient to detect, and based on the traditional three-way valve, the three-way valve for sampling is specially improved. Disclosure of utility model The utility model is provided in view of the problems that the prior three-way valve is difficult to sample fluid in the valve body, the operation is relatively complicated, the efficiency is low and the detection is inconvenient.
