Abstract

一种隔膜泵，由泵体、泵盖和进水阀、排水阀所组成，在泵盖与泵体之间安装碗形的橡胶隔膜，橡胶隔膜与泵体组成泵腔，橡胶隔膜上连接动力机构。当动力机构带动橡胶隔膜向上运行时，泵腔容积扩大，进水阀打开进水，而橡胶隔膜向下运行时，泵腔容积缩小，排水阀打开排水。整个泵的构造简单，加工省力，使用方便，特别适用于船底吸水和水井抽水等。

Description

隔膜泵
                        技术领域
本实用新型涉及泵，特别是涉及水泵，主要适用于船底吸水或井水抽水等，可采用手动或者机动。
                        背景技术
泵是一种通用机械，种类很多。但已有泵的壳体与运动部件相分离，又有进、出阀门等各个组件，因此构造比较复杂，重量重，加工另件多，生产成本高，而且固定安装又麻烦。
                        发明内容
本实用新型提供一种隔膜泵，结构十分简单，操作也方便。该泵的技术方案是：由泵体、泵盖和进水阀、排水阀所组成，在泵盖与泵体之间安装碗形的橡胶隔膜，橡胶隔膜与泵体组成泵腔，橡胶隔膜上连接动力机构。工作时当动力机构带动橡胶隔膜向上运动，泵腔容积扩大，排水阀关闭，进水阀打开进水，当橡胶隔膜向下运动，泵腔容积缩小，进水阀关闭，排水阀打开排水。整个泵的构造十分简单，橡胶配件不需金加工，并且隔膜和阀片与泵体相固定，生产、安装费用省，移动和使用非常方便。
                       附图说明
图1是本实用新型隔膜泵结构示意图。
1、泵体；2、排水阀；3、泵盖；4、橡胶隔膜；4′橡胶隔膜在上止点；5、动力机构；6、进水阀；7、泵腔。
                     具体实施方式
本实用新型涉及一种隔膜泵，基本结构是泵体、泵盖和进水阀、排水阀等所组成，在泵体1的俯视方向其内腔是略呈圆桶形，泵盖3是呈环形，主要特点是一个碗形体的橡胶隔膜4，橡胶隔膜4的边缘向外伸展，被泵盖3和泵体1相固定安装，橡胶隔膜4与泵体1组成密封的泵腔7，橡胶隔膜4上连接动力机构5，动力机构5可以是手动，也可以是机动。所述阀门是单向性开闭的橡胶阀片构成进水阀6和排水阀2。如图1所示，当动力机构带动橡胶隔膜4′在上止点时，泵腔7容积最大，这个过程进水阀6打开进水，而当橡胶隔膜4向下到下止点过程中，进水阀关闭，而排水阀2打开排水。该泵还可以由两组或多组结构组合，达到连续进水和连续排水。
