Abstract

The invention discloses a pipeline control valve and particularly discloses a labyrinth adjusting valve, comprising a valve body, a valve seat, a spool, a labyrinth sleeve assembly, a bonnet and a valve stem. The valve body is provided with a medium inlet and a medium outlet, the labyrinth sleeve assembly comprises one or more labyrinth plates, one or more guide plates, an upper plate and a lower plate, and the labyrinth plates and the guide plates are located between the upper plate and the lower plate; each labyrinth plate has a flow passage, and/or each guide plate has a flow passage. In conclusion, the labyrinth adjusting valve provided herein can reduce medium flow speed in a medium flowing process, thus reducing the adjusting valve outlet flow speed under high temperature, great pressure difference and high flow speed and solving the problem that cavitation, high noise and severe vibration are caused when a medium passes through the adjusting valve.

Description

technical field [0001] The invention relates to a pipeline control valve, in particular to a labyrinth regulating valve used to control fluid with high pressure difference. Background technique [0002] Regulating valve is a commonly used valve, the main function is to adjust the pressure, flow, temperature and other parameters of the medium. The main structure of the regulating valve is composed of valve body, valve seat, valve core and valve cover. The valve seat is installed in the valve body. The valve seat is a hollow cylindrical structure. The valve core is located in the valve seat. Opening or closing of media channels. [0003] Ordinary regulating valve, when the medium flows to the valve core, due to the throttling effect of the valve core and the valve seat, a necking phenomenon occurs, so the speed will increase rapidly, and the pressure will decrease rapidly. In this case, the medium vaporizes , forming bubbles. When the medium flows through the constriction f...
