Description

一种新型片阀型隔膜泵 技术领域
本发明涉及到隔膜泵的技术领域，尤其涉及到一种新型片阀型隔膜泵。
背景技术
隔膜泵是一种新型液态物料输送设备，可部分替代潜水泵、排污泵、离心泵等设备的使用。该泵具备体积小、重量轻、安装使用方便灵活等特点。因其可输送含固体颗粒的液体，不存在防爆方面的问题等优点，在石化、涂料、船舶、水处理、食品、市政、矿山、电站等越来越多的行业中普遍使用。
现有的片形单向阀采用在泵体内用螺栓固定单向阀来解决，这种方案如果遇到输送腐蚀性的液体时，则会因为螺栓的腐蚀而无法使用。且采用现有的结构不仅零件多，维护不便，且泵体与球形单向阀的泵体不能通用，造成生产及使用成本很高，同时，因在泵体上另外还有两个密封接入位置，不方便加工，且液体流道复杂，影响设备的工作效率。
发明内容
本发明的目的在于提供一种新型片阀型隔膜泵，用于解决上述技术问题。
本发明采用的技术方案如下：

进一步，作为一种较佳的实施方式，每一弯头5的水平段的一端均开设有第一阀瓣座孔10，每一阀瓣座4的一侧分别设于一第一阀瓣座孔10内，每一三通接管2的一端分别与一弯头5的水平段的一端通过螺栓连接，且每一三通接管2的水平段的两端均开设有第二阀瓣座孔11，用于固定阀瓣座4的另一侧，阀瓣3设于阀瓣座4内并与第一限位套9相抵。第一限位套9的另一端的表面与水平段的一端表面齐平。三通接管2的进出口采用螺纹与法兰的叠加设计，可应用在更多的使用现场，满足不同用户的需求。三通接管 2旋转45°时，法兰的接口方向也可以转变成斜向的，安装方向更加灵活。
进一步，作为一种较佳的实施方式，第一阀瓣座孔10内设有第一定位凸台，第二阀座孔11内设有第二定位凸台，第一定位凸台与第二定位凸台相对应，阀瓣座4的两侧均开设有定位凹槽，定位凹槽与第一定位凸台和第二定位凸台正对。阀瓣座4的两侧外缘均设有密封垫12。将阀瓣3放置于阀瓣座4内，将阀瓣座4的一侧的定位凹槽与弯头5上的第一定位凸台相连接，连接后再将三通接管2的一侧第二定位凸台与阀瓣座4的另一侧连接，将阀瓣座4固定。
进一步，作为一种较佳的实施方式，还包括阀瓣轴，阀瓣3的一端设有阀瓣轴，阀瓣座4的密封面一侧上端开设有阀瓣轴槽，阀瓣轴设置于阀瓣轴槽内。阀瓣座4的密封面与阀瓣3的垂直面之间以阀瓣轴的圆心为原点设有夹角。夹角可使的阀瓣3在密封时，有一个横向的分力，保证密封可靠。阀瓣3座的内部位于阀瓣3的下侧设有一向下倾斜的坡度，坡度的设计可加快液体内颗粒物的流动，以防因颗粒物的停滞，造成单向阀关闭不严。阀瓣3座的下侧内壁开设有斜面加工孔。斜面加工孔可减少液体输送时的流阻，提高流通能力。阀瓣3的厚度增加后，强度增强，不会发生变形或破裂的现象，密封性更好，还可堆焊硬质合金以适应更多的使用场合。阀瓣3可两面使用，方便安装维护。
进一步，作为一种较佳的实施方式，还包括吊环13，每一弯头5上分别设有一吊环13，每一吊环13上分别开设有圆弧形孔14，圆弧形孔14供吊钩穿设，吊环13通过螺栓与弯头5连接。采用特殊设计的吊环13，下端用螺栓固定在弯头5上，上端开有半圆弧形孔14，吊装时挂钩可横向伸进，在 起吊时挂钩可始终保持在顶端，保证平稳起吊隔膜泵。当三通接管2接口在水平位置时，吊环13竖直安装，而当三通接管2不在水平位置时，可旋转吊环13，挂钩起吊时又处于圆弧与直线的顶端，确保隔膜泵方便吊装。吊装完成后，如不再需要吊环13，可将吊环13拆下保存。
进一步，作为一种较佳的实施方式，还包括安装底座7，泵体1的下端两侧设有安装底座7。安装底座7可以将新型片阀型隔膜泵支撑立于地面之上，放置更加稳定。
以上所述仅为本发明较佳的实施例，并非因此限制本发明的实施方式及保护范围，对于本领域技术人员而言，应当能够意识到凡运用本发明说明书及图示内容所作出的等同替换和显而易见的变化所得到的方案，均应当包含在本发明的保护范围内。
