Abstract

本实用新型涉及一种手动泵,具体地说是一种手动真空吸泵,主要由进气盖(1)、气囊(2)、阀门(3)、阀门(4)、(5)组成,其特点是只要用手连续按动气囊几下,就可以把液体从一个容器吸入另一个容器内,需要停止时,只要把进气盖松开即可。

Description

手动真空吸泵
本实用新型涉及一种手动泵,具体地说是一种手动真空吸泵。
现有手动泵种类很多,比如手动水压机井泵,它采用活塞上有一个单向阀、连杆操纵机构,活塞上移单向阀关闭,水在大气压的作用下上升,活塞下移单向阀打开,管内空气排出,往复运动多次把水抽出,就是利用真空原理,但此种泵体积大、结构较复杂、操作不方便。目前手动泵最大缺点是不能连续工作。
本实用新型的目的,提供一种体积小、重量轻、使用方便且能连续工作的手动真空吸泵。
本实用新型的要点是:把二个单向阀装入一个泵体内,按动气囊时,一个单向阀打开另一个单向阀关闭,使泵体内形成真空,在大气压作用下,把液体从容器中吸出。为减轻重量,泵体采用塑料制成。
本实用新型手动真空吸泵主要由进气盖、气囊、泵体,二个单向阀门组成(参看附图1),把阀门(4)、阀门(5)装入泵体(3)内,气囊(2)通过螺纹扭紧在泵体上,不允许漏气,进气盖(1)通过螺纹扭在气囊上,需要工作时,把进盖扭紧,按动气囊时,阀门(4)关闭,阀门(5)打开,气囊和泵体内的空气排出,连续按动几下气囊,气囊和泵体内形成真空,这时停止按动气囊,液体在大气压的作用下,就从阀门(4)进入泵体,从阀门(5)流出,需要停止工作时,只要把进气盖松开,空气进入气囊中即可。
本实用新型的优点是:体积小、结构简单、重量轻、使用方便,最大优点是可以连续工作,适用范围广。
