Title (EN) NON-CONTACT FLOW RATE CONTROL SYSTEM HAVING FULLY-ENCLOSED CAVITY
(FR) SYSTÈME DE COMMANDE DE DÉBIT SANS CONTACT COMPRENANT UNE CAVITÉ COMPLÈTEMENT FERMÉE
(ZH) 腔体全封闭非接触式流量控制系统
Abstract:
(EN) A non-contact flow rate control system having a fully-enclosed cavity, comprising: a housing, a flow rate control unit and an operating unit; the housing is provided with a fluid inlet (111), a fluid outlet (131), and a fluid passage that extends between the fluid inlet and the fluid outlet; the flow rate control unit is disposed in the fluid passage, and the operating unit is disposed at an outer side of the housing; the operating unit comprises an operating element and an outer magnet (22) that is fixed on the operating element; the flow rate control unit comprises a flow rate control element and an inner magnet (42) that is fixed on the flow rate control element; the flow rate control element may move under the action of the magnetic force between the outer magnet (22) and the inner magnet (42) when the operating element moves relative to the housing, thereby changing the flow rate of a system. The system achieves non-contact control by means of utilizing magnetic field characteristics, thus ensuring that a cavity of the housing is fully enclosed, thereby improving the reliability of the system in terms of leakage prevention.
(FR) L'invention concerne un système de commande de débit sans contact comprenant une cavité complètement fermée comprenant : un boîtier, une unité de commande de débit et une unité de fonctionnement ; le boîtier est doté d'une admission de fluide (111), d'une évacuation de fluide (131) et d'un passage de fluide qui s'étend entre l'admission de fluide et l'évacuation de fluide ; l'unité de commande de débit est disposée dans le passage de fluide et l'unité de fonctionnement est disposée au niveau d'un côté externe du boîtier ; l'unité de fonctionnement comprend un élément de fonctionnement et un aimant externe (22) qui est fixé sur l'élément de fonctionnement ; l'unité de commande de débit comprend un élément de commande de débit et un aimant interne (42) qui est fixé sur l'élément de commande de débit ; l'élément de commande de débit peut se déplacer sous l'action de la force magnétique entre l'aimant externe (22) et l'aimant interne (42) lorsque l'élément de fonctionnement se déplace par rapport au boîtier, ce qui permet de modifier le débit d'un système. Le système réalise une commande sans contact au moyen de caractéristiques de champ magnétique, ce qui permet de garantir qu'une cavité du boîtier est complètement fermée, ce qui permet d'améliorer la fiabilité du système en termes de prévention de fuites.
(ZH) 一种腔体全封闭非接触式流量控制系统,包括壳体、流量控制单元和操作单元,壳体具有流体进口(111)、流体出口(131)以及在流体进口和流体出口之间延伸的流体通道,流量控制单元设置在流体通道中,操作单元设置在壳体的外侧,其中,操作单元包括操作元件和固定在该操作元件上的外磁体(22),流量控制单元包括流量控制元件和固定在该流量控制元件上的内磁体(42),当操作元件相对于壳体运动时,流量控制元件能够在外磁体(22)和内磁体(42)之间的磁力的作用下运动,从而改变系统的流量。该系统通过利用磁场特性实现非接触式控制,由此确保壳体腔体的全封闭性,从而在防泄漏方面提高了系统的可靠性。
