Three-way pipeline with flow control function

Abstract

The invention relates to the technical field of food chromatographic detection, and discloses a three-way pipeline with a flow control function. The three-way pipeline with the flow control function comprises a main pipe body, a long branch pipe body and a short branch pipe body, wherein an opening and closing mechanism is fixedly connected to the interior of a central pipe body; the opening and closing mechanism comprises a fixed disc; the right end of the fixed disc is fixedly connected onto the left end of the main pipe body; two through grooves are formed in the fixed disc; an annular groove is formed in the fixed disc; flow control mechanisms are arranged in the two through grooves; and a rotating mechanism is arranged at the end, away from the main pipe body, of the fixed disc. The rotating mechanism is arranged to be matched with the opening and closing mechanism and the two flow control mechanisms, meanwhile, when the rotating mechanism is controlled to rotate, the two flow control mechanisms can be driven to open the positions, communicated with the long branch pipe body and the short branch pipe body, in the main pipe body, and when the rotating mechanism rotates, two short columns drive two closing plates to be opened at equal ratio amplitude, so that the flow velocity of the fluid from the main pipe body to the long branch pipe body and the short branch pipe body can be controlled at equal ratio, and the use convenience of an operator is greatly improved.

Description

technical field [0001] The invention relates to the technical field of food chromatographic detection, in particular to a three-way pipeline with a flow control function. Background technique [0002] In the food and drug inspection, it is necessary to carry out chromatographic detection of the product, and the three-way pipe is mainly used to change the direction of the fluid flow, and to control the speed of the fluid flowing from the main pipe and the branch pipe. Most of the control is separate regulation, and the flow rate is controlled by adjusting the two branch pipes separately, but this operation increases the time for the user to adjust, and cannot accurately adjust the ratio of the flow rate of the two branch pipes. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a three-way pipe with a flow control function, which can control the flow rate of the fluid from th...
