Technical Problem

[0003]然而现有的PVC材质的摆动式底阀通常螺栓将球笼安装于阀座顶部，阀芯设置在球笼内部，球笼在使用时能够避免大体积杂质进入阀体内部，一定程度上起到防堵塞阀瓣的效果，但是小颗粒杂质淤积也会使得阀瓣闭合不到位，影响密封，因此需要定期拆卸清洁，然而阀芯、球笼和阀座之间存在多个密封件，而螺栓安装方式拆卸麻烦，多次拆装不仅会损坏安装部，也会损坏密封部，为此特提供一种改良型摆动式底阀

Benefits of technology

[0016] By inserting the plug-in sealing part at the bottom of the mounting base into the support ring inside the valve cavity, and making the support part abut against the top of the support ring, and then threading the mesh cage into the internal threaded connection part, and making the bottom end of the external threaded connection part abut against the top of the support part, while the top of the mounting base abuts against the retaining ring, a soft seal is achieved between the valve seat, mesh cage and valve core, which facilitates quick sealing and allows for quick removal and cleaning of the valve core when it becomes blocked.
