一种适于气力输送系统的预关闭阀门
技术领域
本发明涉及一种阀门，特别是涉及一种适于气力输送系统的预关闭阀门。
背景技术
气力输送系统包括进料装置、仓泵、输送管道、进气装置、储库及储库设备、动力气源、PLC/DCS控制系统等。
气力输送系统用的进料阀在使用过程中，当仓泵料满关闭进料阀时，由于落料还在进行，容易使进料阀椎体与密封圈间夹颗粒物料，导致进料阀关闭不严。一旦进料阀关闭不严，压缩空气夹带颗粒物料将磨损进料阀椎体，直至进料阀不能正常工作，影响气力输送系统安全稳定的运行。
现有气力输送系统在进料阀上方无预关闭阀。因此，致进料阀关闭不严造成进料阀椎体与密封圈间夹颗粒物料而磨损，使系统维护工作量大和运行费用高。
发明内容
本发明的目的在于提供一种适于气力输送系统的预关闭阀门，本发明预关闭阀安装在系统进料阀上方，解决了进料阀椎体与密封圈间夹颗粒物料而磨损。使系统运行可靠，提高自动化程度，送气比高，流速低，维护工作量小和运行费用低。
本发明的目的是通过以下技术方案实现的：
一种适于气力输送系统的预关闭阀门，所述预关闭阀包括两个半圆阀体 通过螺栓连接一体，圆阀体与阀座通过螺栓相连，圆阀体与阀座相连接处、安装有轴承和密封圈，转轴穿过阀座、轴承、密封圈装入圆阀体中，不锈钢材质转轴的底部设有不锈钢材质得翻转阀板，转轴的顶部固定连接有气动执行机构；气动执行机构通过螺栓固定到阀座上；转轴的顶部固定连接气动执行机构，气动执行机构通过转轴的转动连接翻转阀板，气动执行机构外侧设有位置检测开关，位置检测开关通过电路控制连接着阀门。
所述的一种适于气力输送系统的预关闭阀门，所述预关闭阀完全关闭后翻转阀板与圆阀体内壁留有0.2~0.5mm的间隙。
所述的一种适于气力输送系统的预关闭阀门，所述转轴与圆阀体连接处设有轴承和二道密封圈。
所述的一种适于气力输送系统的预关闭阀门，所述预关闭阀安装在气力输送系统进料阀的上端。
本发明的优点与效果是：
本发明设计的预关闭阀安装在进料阀上方，解决了进料阀椎体与密封圈间夹颗粒物料而磨损。使系统运行可靠，提高自动化程度，送气比高，流速低，维护工作量小和运行费用低。
