Title (EN) EFFICIENT EVACUATION APPARATUS
(FR) APPAREIL D’ÉVACUATION EFFICACE
(ZH) 一种高效抽真空装置
Abstract:
(EN) An efficient evacuation apparatus, comprising a sealed can (1), a first piston (2), telescopic rods (3), a vacuum pump (4), a driving device, one-way valves (21), a pressure sensor, and an electric control device (8). An air pipe (5) is communicated with an external apparatus to be evacuated by means of an air valve (6). Under the reciprocating driving action of the telescopic rods (3), the first piston (2) can continuously squeeze the air in the sealed can (1) to a position above the sealed can (1) in cooperation with the one-way valves (21) disposed on the first piston (2), and then evacuates the air by means of the vacuum pump (4), so that the sealed can (1) always maintains a certain degree of vacuum, and thus an evacuation operation of the external apparatus to be evacuated can be instantly completed by means of the air pipe (5) when evacuation is required.
(FR) L'invention concerne un appareil d'évacuation efficace comprenant une boîte étanche (1), un premier piston (2), des tiges télescopiques (3), une pompe à vide (4), un dispositif d'entraînement, des soupapes unidirectionnelles (21), un capteur de pression et un dispositif de commande électrique (8). Un tuyau d'air (5) est en communication avec un appareil externe devant être évacué au moyen d'une soupape pneumatique (6). Sous l'action d'entraînement selon un mouvement de va-et-vient des tiges télescopiques (3), le premier piston (2) peut presser en continu l'air dans la boîte étanche (1) jusqu'à une position au-dessus de la boîte étanche (1) en coopération avec les soupapes unidirectionnelles (21) disposées sur le premier piston (2), puis évacue l'air au moyen de la pompe à vide (4), de sorte que la boîte étanche (1) conserve toujours un certain degré de vide, et une opération d'évacuation de l'appareil externe devant être évacué peut ainsi être instantanément réalisée au moyen du tuyau d'air (5) lorsqu'une évacuation est nécessaire.
(ZH) 一种高效抽真空装置,包括密封罐(1)、第一活塞(2)、伸缩杆(3)、真空泵(4)、驱动装置、单向阀(21)、压力传感器以及电控装置(8),气管(5)通过气阀(6)与外部待抽真空装置贯通设置。第一活塞(2)在伸缩杆(3)的往返驱动作用下,配合设置在第一活塞(2)上的单向阀(21),可将密封罐(1)内的空气不断挤压至密封罐(1)的上方,之后通过真空泵(4)的作用将其排空,以此使得密封罐(1)始终保持一定的真空度,之后在需要抽真空时可通过气管(5)瞬间完成对外部待抽真空装置的抽真空作业。
