Intelligent flow controller

Abstract

The invention provides an intelligent flow controller. The intelligent flow controller includes a ball valve body and a valve stem, a first flange is welded to the left end of the ball valve body, a second flange is welded to the right end of the ball valve body, a flow accumulator is mounted on the upper side of the outer surface of the left end of the ball valve body, a cylinder is mounted in the middle of the upper side of the outer surface of the ball valve body, and a cover plate is mounted on the upper end face of the cylinder through bolts; and a servo motor is mounted on the lower sideof the interior of the cylinder, the output end of the servo motor is fixedly connected with the valve stem through a coupling, a programmable logic controller is mounted on the upper side of the interior of the cylinder, a water storing cover is welded to the annular side face of the cylinder, a water adding opening is formed in the right side of the upper end face of the water storing cover, asmall stop valve is mounted on the right side of the outer surface of the lower end of the water storing cover, and an asbestos board is pasted in the middle of the upper end face of the cover plate through glue. Compared with the prior art, the intelligent flow controller has the following beneficial effect of achieving the purpose of thermal insulation failure rate reducing.

Description

technical field [0001] The invention is an intelligent flow controller, which belongs to the technical field of flow control. Background technique [0002] It is known that in pipeline laying, it is often necessary to install a flow control valve in the pipeline. With the development of intelligent technology, the method of using a programmable logic controller to control the servo motor to open or close the flow control valve is more and more widely used, and storage The cylinders of servo motors and other components often fail due to high temperature due to the lack of heat insulation structure in high temperature weather. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent flow controller to solve the problems raised in the above-mentioned background technology. The present invention has a heat insulation structure, low failure rate and high reliability. [0004] In order to a...
