Abstract

一种用于粉体物料输送系统的正压密相气力输送单向阀，它包括有进气嘴和阀座，与进气嘴相连接有阀芯，该阀芯的上部设置有与进气嘴的进气孔相连通的中心盲孔，在阀芯的圆柱面上设置有与中心盲孔相连通的径向出气口，套装在阀芯的圆柱上有出气口封闭胶套；一阀体的上端连接阀芯，下端连接阀座，其阀体与阀芯之间形成一进气阀腔，该进气阀腔与阀座的进气孔相连通。本实用新型结构简单，工作稳定可靠，并且具有密封面积大、动作迅速、密封件更换方便的特点，能够满足正压密相气力输送粉体物料系统的工作要求。

Description

正压密相气力输送单向阀
技术领域
本实用新型涉及单向阀，具体涉及一种正压密相气力输送单向阀。
背景技术
在正压密相气力输送粉体物料的系统中，由于其系统内输送的是气体和粉体组成的两相流体，在对发送仓及输送管道的各加压点进行加压时，需要使用单向阀，以防止气固两相流体外溢，造成污染，堵塞气路等问题发生。现有技术的单向阀，主要应用于气动系统和液压系统，不仅结构相对复杂，而且应用于正压密相气力输送粉体物料系统中也不能满足系统工作要求。
发明内容
本实用新型的目的在于提供一种能够满足正压密相气力输送粉体物料系统工作要求的正压密相气力输送单向阀。
实现上述目的的技术方案是：一种正压密相气力输送单向阀，它包括有进气嘴和阀座，与所述的进气嘴相连接有一阀芯，该阀芯的上部设置有与进气嘴的进气孔相连通的中心盲孔，在阀芯的圆柱面上设置有与中心盲孔相连通的径向出气口，套装在阀芯的圆柱面上有出气口封闭胶套；一阀体的上端与阀芯相连接，下端与阀座相连接，其阀体与阀芯之间形成一进气阀腔，该进气阀腔与阀座的进气孔相连通。
本实用新型的技术方案还包括：在所述阀芯上设置有与封闭胶套相配合的环形凸台。
本实用新型结构简单，工作稳定可靠，并且具有密封面积大、动作迅速、密封件更换方便的特点，能够满足正压密相气力输送粉体物料系统的工作要求。
附图说明
附图是本正压密相气力输送单向阀结构主剖视图。
具体实施方式
结合附图对本实用新型的具体实施方式进行说明。
如附图，本正压密相气力输送单向阀包括有与高压气管相连接的进气嘴1和固定在输送管道或发送仓上的阀座6，与进气嘴1相连接有阀芯2，其阀芯2的上部设置有与进气嘴1的进气孔相连通的中心盲孔，在阀芯的圆柱面上设置有与中心盲孔相连通的径向出气口4，其出气口沿阀芯柱面圆周均匀分布2-4个，且连通中心盲孔与出气口的孔向下倾斜设置。套装在阀芯2的圆柱面上有出气口封闭胶套5。阀体3的上端经螺纹连接阀芯2，下端经螺纹连接阀座6，其阀体3与阀芯2之间形成一环形进气腔，该进气腔的下端与阀座6的进气孔相连通。
本实用新型在阀芯2上设置有与封闭胶套5相配合的环形凸台7，用于加强封闭胶套与阀芯相对位置的稳定性。
如附图实施例，本实用新型在阀体3与阀芯2的连接端面上及阀体3与阀座6的连接端面上分别设置有用于连接密封的密封圈。
