Description

一种适用于高低温环境的隔膜阀
技术领域
本发明涉及阀门技术领域，尤其涉及一种隔膜阀。
背景技术
传统的隔膜阀，隔膜与阀体之间通过密封材料进行密封，密封材料大都使用工业密封胶和氟胶等，密封可靠性差，并且耐高温、低温性能差。
发明内容
为了克服传统隔膜阀存在的上述问题，本发明提供了一种适用于高低温环境下的隔膜阀。
本发明为实现上述目的所采用的技术方案是：一种适用于高低温环境的隔膜阀，包括上阀体3和下阀体5，上阀体3内设有阀杆1，下阀体5下部设有流体进口6和流体出口7，阀板2焊接于下阀体5上。
本发明的适用于高低温环境的隔膜阀，隔膜与阀体之间采用金属材料钎焊密封，改善了阀的构造，提高了阀的密封性能和耐高、低温性能。
附图说明
图1是本发明适用于高低温环境的隔膜阀主视剖面图。
图中：1、阀杆，2、阀板，3、上阀体，4、焊接部位，5、下阀体，6、流体进口，7、流体出口。
具体实施方式
本发明的适用于高低温环境的隔膜阀结构如图1所示，包括上阀体3和下阀体5，上阀体3内设有阀杆1，下阀体5下部设有流体进口6和流体出口7，阀板2（隔膜）焊接于下阀体5上。
本发明将隔膜与阀体焊接在一起，采用特殊金属材料钎焊密封，使阀的密封型、可靠性显著提高，对使用环境温度范围也可大幅提升。
本发明是通过实施例进行描述的，本领域技术人员知悉，在不脱离本发明的精神和范围的情况下，可以对这些特征和实施例进行各种改变或等效替换。另外，在本发明的教导下，可以对这些特征和实施例进行修改以适应具体的情况及材料而不会脱离本发明的精神和范围。因此，本发明不受此处所公开的具体实施例的限制，所有落入本申请的权利要求范围内的实施例都属于本发明的保护范围。
