具体实施方式:
下面结合附图对本发明作进一步说明:集输式分体控制阀包括阀体3、阀座11、阀套6及阀杆4,阀体3的内腔设有进液口22、控制口9及出液口18,进液口22端部固定安装有连接法兰A23,阀体3的控制口9内孔设有螺纹,阀体3的内腔中水平方向设有隔层19,隔层19将阀体3内腔划分为进液端和出液端,隔层19上设有液流通道c21,液流通道c21将进液端与出液端连通,隔层19的上端面与阀座11的下端面配合安装,隔层19的上端面与阀座11的下端面之间通过密封胶圈a1密封;阀座11的底部设有液流通道b20,阀座11的径向设有液流通道a2,控制口内孔、液流通道b20及液流通道c21保持同一轴线,以确保阀杆对液流通道的可靠密封,更换阀杆后不会影响阀门的密封效果,进液口22与阀座11内腔通过液流通道a2连通,阀座11内腔通过液流通道b20及液流通道c21与出液口18连通,液流通道a2、液流通道b21及液流通道c21成为进液口与出液口之间唯一的连通通道,阀座11的上端配合安装有阀套6,阀套6下端的外部通过螺纹配合安装在阀体3的控制口9内,旋转阀套6使其相对于阀体3下行,使得安装在阀套6下端的阀座11的下端面与隔层19上端面紧密配合 在一起,实现阀座11与隔层19之间的端面密封,阀体3的控制口9上端外部安装有备帽8,备帽8与阀体3控制口9外部通过螺纹连接,备紧备帽8,备帽8将阀套6锁定在阀体3内;避免旋转阀杆4或误操作造成阀座11与隔层19之间的密封失效或影响流量的控制,阀套6的内孔设有内凸台,内凸台上设有螺纹,阀杆4配合安装在阀套6内,阀杆4与阀套6通过螺纹连接,阀杆4的下部设有凸台,凸台上设有两道密封沟槽,密封沟槽内安装有密封胶圈b10,阀套6内凸台的下端面7对阀杆4的上行起到限位的作用,阀杆4的下端部设为密封端头12,阀杆4的上部伸出在阀套6外,阀杆4的上端安装有手轮5,通过搬动手轮5来调整阀杆4的密封端头12与液流通道c21之间的距离,从而实现对阀内液流流量的控制。
当阀门密封失效时,卸下手轮5及备帽8,旋转阀套6,阀套6就会带动阀杆4一起脱出阀体3,更换阀杆4后,再重新安装好就可以了,相比更换整个控制阀,操作简单,降低了维修成本,阀体3的右端出液口18外部配合安装有密封套14,密封套14的右端外部通过螺纹连接有连接法兰B17,出液口18的端部安装有固定挡环15,固定挡环15起到轴向限位的作用,进液口22与出液口18的外部均安装有测压阀24及压力表24,可以即时显示进液与出液的液流压力,
阀杆4的密封端头12设为圆锥体、采用硫化橡胶制成,硫化橡胶具有很好的密封性能,当密封端头12与液流通道c21紧密配合时,就隔断了阀体3内进液口22与出液口18的连通,阀门关闭,密封安全可靠。
密封套14与出液口18外部之间安装有密封胶圈c13,密封套14与连接法兰B17之间安装有密封垫16,连接法兰B17带动密封套14可以与阀体3即能相对伸缩又能确保安全密封,当整体集输分体式控制阀安装时,可以消除管线安装所产生的变形应力,拆卸时无需撬动管线,只需将连接法兰B17回缩,就可以顺利地完成操作,节省了人力,而连接管线也不会产生因维修造成的损伤,延长了连接管线的使用寿命,具有很好的经济效益和社会效益。
