The utility model discloses a non-retaining full-package three-piece manual valve, which comprises a valve body, a valve spool, a valve cover and a valve seat. The two ends of the valve body are fixedly connected with the valve cover by bolts, and a direct medium flow channel is formed inside the valve body. A sealing ring is arranged between the valve body and the valve cover, and two valve seats are arranged in the flow channel. A sealing ring is arranged between the valve seat and the valve body. A sealing ring is arranged between the valve seat and the valve cover. The valve core is located between two valve seats. A flat groove is arranged on the valve core. The flat groove is connected and fixed to one end of the valve stem. The other end of the valve stem is penetrated through the valve body and is connected with a manual flow control wrench. A valve stem sealing ring is arranged between the valve stem and the valve body. The utility model changes the whole structure, the structure is three-piece, and adopts a full-enclosed valve seat, and a sealing ring is arranged between each piece and the valve seat, which not only facilitates installation and disassembly, but also ensures the sealing performance.
【技术实现步骤摘要】
无滞留全包三片式手动阀
本技术属于机械阀门领域,尤其涉及无滞留全包三片式手动阀。
技术介绍
目前在医疗器械领域多使用二片式的球阀,这种球阀用于医药行业中使用中容易造成卫生死角,介质残留在球阀中。阀门内腔无法清洗,密封件损耗后整个阀门不方便或无法维修,造成系统维护成本增加,同时,阀门整体在管路中的安装拆卸不便。
技术实现思路
本技术的目的在于提供无滞留全包三片式手动阀,其改变了整体的结构,结构呈三片式,并且采用全包式阀座,各片与阀座之间均设置密封圈,不仅方便安装拆卸,还保证密封性能。本技术为解决以上技术问题,采用如下技术方案:无滞留全包三片式手动阀,包括阀体、阀芯、阀盖和阀座,所述阀体两端通过螺栓与所述阀盖固定连接,其内部形成直通的介质流通通道,所述阀体与所述阀盖之间设有密封圈,所述流通通道内设有二片阀座,所述阀座与所述阀体之间设有密封圈,所述阀座与所述阀盖之间设有密封圈,所述阀芯位于二片阀座之间,所述阀芯上设有扁槽口,所述扁槽口连接固定连接至阀杆一端,所述阀杆另一端穿出所述阀体后与手动流量控制扳手连接,所述阀杆与所述阀体之间设有阀杆密封圈。采用以上技术方案,本技术具有以下优点:本技术改变了整体的结构,结构呈三片式,并且采用全包式阀座,各片与阀座之间均设置密封圈,阀体与阀盖之间设置密封圈,阀体与阀杆之间设置多个阀杆密封圈,使得阀门内部不会形成空区,介质不会滞留在阀门内,形成无滞留密封,保证阀门整体密封性能,而且各片之间采用螺栓固定,方便安装拆卸。作为本技术的进一步优化,所述阀体顶端固定连接有固定支架,所述固定支架上连接有回信器。采用以上技术方案,本技术采用回信器作为 ...
