Description

气动进排料阀
技术领域
本实用新型涉及一种阀门，尤其是一种气动进排料阀。
背景技术
气动进排料阀是用于物料在高压状态下迅速混流经发送器进入管道的开启物、气两相流阀。它也是气力输送关键设备之一。但是现在所使用的气动进排料阀的密封效果差，端盖与阀芯之间的摩擦力大，使用寿命短，容易损坏。目前，还未有好的解决方案。
实用新型内容
本实用新型的技术任务是针对上述现有技术中的不足提供一种气动进排料阀，该气动进排料阀具有密封效果好，端盖与阀芯之间的摩擦力小，使用寿命长，不易损坏，使用方便等特点。
本实用新型解决其技术问题所采用的技术方案是：它包括壳体、端盖、气缸和阀芯，所述的端盖设置在壳体两侧，所述的气缸设置在壳体的上部，所述的壳体与气缸和端盖之间分别通过螺栓连接，所述的阀芯通过拉杆与气缸相连，所述的壳体与拉杆之间设置有V型密封圈，所述的端盖与阀芯的接触面之间分别设置有圆环型密封件，所述的两端盖的内侧分别设置有条型密封件，所述的条型密封件凸出端盖端面。
所述的阀芯包括阀板、拐臂、顶头和弹簧，所述的拐臂设置在两侧阀板的中部，拐臂顶部与拉杆相连，所述的拐臂中部设置有弹簧，弹簧的两端分别设置有顶头。
所述的圆环型密封件和条型密封件的材质分别为氧化锆。
本实用新型的气动进排料阀和现有技术相比，具有以下突出的有益效果：端盖与阀芯的接触面之间分别设置有圆环型密封件，端盖的内侧分别设置有条型密封件，密封效果好，端盖与阀芯之间的摩擦力减小，使用寿命增长，耐磨性能更优良，不易损坏，造价低，使用方便等特点。

具体实施方式
参照说明书附图1至附图6对本实用新型的气动进排料阀作以下详细地说明。
本实用新型的气动进排料阀，其结构包括壳体3、端盖4、气缸1和阀芯，所述的端盖4设置在壳体3两侧，所述的气缸1设置在壳体3的上部，所述的壳体3与气缸1和端盖4之间分别通过螺栓11连接，所述的阀芯通过拉杆5与气缸1相连，所述的壳体3与拉杆5之间设置有V型密封圈2，所述的端盖4与阀芯的接触面之间分别设置有圆环型密封件6，所述的两端盖4的内侧分别设置有条型密封件12，所述的条型密封件12嵌入端盖内侧的凹槽内，条型密封件12外表面凸出端盖4端面。
所述的阀芯包括阀板7、拐臂8、顶头9和弹簧10，所述的拐臂8设置在两侧阀板7的中部，拐臂8顶部与拉杆5相连，所述的拐臂8中部设置有弹簧10，弹簧10的两端分别设置有顶头9。弹簧10将两端的顶头9紧密压在阀板7上，使阀板7与端盖4之间配合紧密。
所述的圆环型密封件6和条型密封件12的材质分别为氧化锆，磨削精度较高，阀板7沿端盖4上下移动时，大大减小端盖4与阀板7之间的摩擦力，从而有效提高密封效果，寿命长，耐磨性能更优良，不易损坏，造价低。
除说明书所述的技术特征外，均为本专业技术人员的已知技术。
