Abstract

PURPOSE: A flow control system is provided to prevent noise or chattering, to regulate the opening degree by covering an opening unit by a valve body with sliding along a partition, and to change a flow control pattern by changing the shape of the opening unit, instead of the shape of a valve. CONSTITUTION: A flow control system(1) embeds a partition(4) for dividing a fluid passage, a valve for regulating the opening degree of an opening unit(5) formed on the partition, and a valve driving device(3) for operating the valve in a case. The valve driving device comprises a motor(30) supplied as a driving source and a transmission mechanism(7) for transmitting the output of the motor to a valve body(6) and rotating and moving the valve within a predetermined range. The valve body rotatively moves with sliding for the partition to regulate the opening degree of the opening unit.

Description

Technical field

[0001] The present invention relates to a flow control device for controlling the flow of various fluids, and more particularly to a valve mechanism of the flow control device. Background technique

[0002] The valve mechanism used in flow control devices that control the flow of LP gas, city gas, refrigerant, or liquid in refrigerators and air conditioners usually uses an electromagnet to drive the valve body.

[0003] However, since the electromagnet repeatedly performs on and off valve opening and closing control, frequent on and off operations are required for high-precision flow control. As a result, there is a problem of noise. In addition, as an inherent problem of the electromagnet itself, vibration may sometimes occur. If it is in this state, it is impossible to perform high-precision control. Summary of the invention

[0004] In view of the above problems, the subject of the present invention is to provide a flow control device that can achieve high-pre...
