The invention discloses a three-way valve for sampling. The three-way valve comprises a valve body, a sealing pipe is arranged on the lower portion of the valve body, through pipes are arranged on thetwo sides of the valve body, and conveying grooves are formed in the axial positions of the through pipes; a positioning pipe is arranged at the upper part of the valve body; a fixing pipe is arranged at the lower end of the positioning pipe; the fixing pipe is fixed at the upper part of the valve body; a rotating shaft is arranged in the valve body; a sealing stud is arranged in the positioningpipe and connected with the positioning pipe through threads; a pressing plate is arranged at the lower end of the sealing stud, and the upper end of the rotating shaft is installed on the lower portion of the pressing plate; a rotating cap is arranged at the upper end of the sealing stud; the outer peripheral surface of the sealing stud is sleeved with a protective spring, and the protective spring is mounted on the pressing plate; and a fixing ring is arranged at the inner bottom of the valve body and installed on the outer circumferential face of the pressing plate. Through the rotating shaft, the rotating stability of the sealing stud can be better; and fluid in a water pipe connector can be conveniently sampled through the positioning pipe.
Description
technical field [0001] The invention relates to a three-way valve, in particular to a three-way valve for sampling. Background technique [0002] The body of the three-way valve has three ports, one in and two out. The difference with ordinary valves is that there is an outlet at the bottom. When the internal spool is in different positions, the outlets are different. For example, when the spool is at the bottom, the left and right are connected. When the right exit is blocked, the left and lower exits are connected. The existing three-way valve body is not convenient for conduction, and the three-way valve body does not have a sampling opening, so the efficiency of sampling the fluid in the three-way valve body is low, and the detection is inconvenient. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a kind of convenient conduction to the inside of the positioning tube through the ...
