如图所示,无需拆卸即可在线更新的纵向旋转阀瓣屏蔽阀,包括阀体1及阀杆12;在所述阀杆12底部固定设有压板组件6;所述压板组件6内侧区域设有阀瓣组件;所述阀瓣组件与压板组件6横向活动相接;在所述阀瓣组件一侧设有旋转步进控制机构,以控制阀瓣组件绕其轴心实现旋转。
本发明所述阀瓣组件包括阀瓣5及横向固定于阀瓣5中部的活动轴2;所述活动轴2两端分别穿过压板组件6两侧长腰孔601;所述阀瓣5底部工作面与阀体1流道内的阀口101相对应;所述旋转步进控制机构设于活动轴2一端。
本发明所述旋转步进控制机构包括棘轮3、摇杆4、驱动棘爪15、制动棘爪16;所述棘轮3与摇杆4位于活动轴2同侧;所述棘轮3与活动轴2一端固定套接;所述摇杆4一端与活动轴2活动轴接;所述驱动棘爪15一端与摇杆4活动轴接;所述驱动棘爪15另一端与棘轮3的齿槽活动插接;所述制动棘爪16一端滑动设于棘轮3的齿背上;在所述制动棘爪16上设有弹性回复件17;在所述阀体1内对应摇杆4端部转动行程区域部位设有限位块7。
本发明在所述活动轴2另一端固定设有导向块14;在所述阀体1腔体内壁对应导向块14位置固定设有导向槽13;所述导向块14置于导向槽13内,且可沿导向槽13纵向上下移动。
本发明所述阀瓣5采用柱状多面体、球体或柱状圆盘型结构。阀瓣5的结构选择具有多样性,只要满足在旋转步进控制机构带动阀瓣5转动一定角度后,阀瓣5对应阀口101的新工作面能与阀口101达到充分密封程度即可。阀瓣内部设置了腹板或实心结构。本发明所述柱状多面体正对阀口101的工作面采用球面结构。本发明在所述阀杆12与阀盖8之间设有弹性屏蔽套11。在具体设计时,本发明所述导向块14可采用轴承结构。
参见图1及图2所示,本发明在具体设计时,其整体结构包括阀体1、活动轴2、棘轮3、摇杆4、阀瓣5、压板组件6、限位块7、阀盖8、手轮9、铜螺母10、屏蔽套11、阀杆12、导向槽13及导向块14等。当阀门的阀口101需要关闭时,通过手轮9转动阀杆12,阀杆12与阀盖8上方铜螺母10配合产生向下的推力作用在压板组件6上,压板组件6下方设置阀瓣5,阀瓣5选择采用柱状多面体结构,参见图1、图6所示,压板组件6压紧
阀瓣5一工作面的同时,对称的阀瓣5另一工作面与阀体的阀口101处组成静密封。当阀门的阀口101开启时,逆向旋转手轮9,阀杆12升起,压板组件6带动阀瓣5升起,参见图2、图7所示,当阀瓣5升起一定高度时,摇杆4触碰到限位块7后倾斜,驱动棘爪15抬起并卡住棘轮3下一个齿,制动棘爪16也同时制止棘轮3转动,从而实现了阀瓣的一面更换。参见图6、图7所示,旋转步进控制机构的具体动作过程:驱动棘爪15拨动棘轮3做间歇运动。驱动棘爪15由摇杆4带动做往复运动,从而带动棘轮3做单向运动。制动棘爪16用以卡住棘轮3,逆向锁死棘轮3,使棘轮3进行单向运动。当摇杆4触碰限位块7后进行逆时针方向摆动时,驱动棘爪15便***棘轮3的齿槽中,使棘轮3跟着转过一定角度,此时,制动棘爪16在弹性回复件17作用下绕其下端固定轴转动,制动棘爪16上端在棘轮3的齿背上滑动。弹性回复件17可采用片簧或牵拉簧结构。当摇杆4顺时针方向转动时,制动棘爪16阻止棘轮3发生顺时针方向转动,而驱动棘爪15却能够在棘轮3齿背上滑过。在具体设计时,限位块7可选择活动销等形式,当发现阀门内漏或者需要更换阀瓣工作面时,限位块7转到设定触碰位置固定,阀瓣转动更换一次工作面,当不需要更换阀瓣工作面时,限位块7移开,棘轮3不转动,阀瓣5也跟着不转动。本发明的优点在于,当需要更换阀瓣工作面时,将限位块7调到设定触碰位置固定,即可通过开启阀门进行更换,即使某一面出现磨损,只需开一次阀门再关一次就可以继续使用,具有一台阀门多个阀瓣的特点。参见图8、图9所示,本发明在所述活动轴2另一端固定设有导向块14;在所述阀体1腔体内壁对应导向块14位置固定设有导向槽13;所述导向块14置于导向槽13内,且可沿导向槽13纵向上下移动。当阀瓣5上下移动时,固定在活动轴2另一端的导向块14沿导向槽13上下滑动或滚动,通过上述结构设计即可确保阀瓣5在上下移动时不至于偏离方向,从而达到阀口101精准密封的目的。
本发明阀杆12外圆周设置有屏蔽套11,屏蔽套11本身具有弹性,随阀杆12升降可以自由伸缩并隔绝介质向外泄露。在阀板组件6的每一面由硬度高的金属制作或表面堆焊耐磨超硬金属,然后再加工成光滑的平面。当需要更换阀瓣工作面时,将限位块7调到设定触碰位置固定,开启阀门,阀瓣5即可通过棘轮3更换一个工作面,即使某一面出现磨损,只需开一次阀门再关一次就可以继续使用,完成一台阀门工作寿命的延长。
参见图10及图11所示,当本发明采用侧面操控阀瓣组件旋转结构时,本发明所述旋转步进控制机构包括侧面控制机构;所述侧面控制机构包括侧杆18;所述侧杆18与阀体1之间设有第二弹性屏蔽套19;所述侧杆18的端部与阀瓣组件中部区域对应;在所述阀瓣组件另一侧设有卡盘20;在所述卡盘20上设有等分机构。
本发明所述侧杆18端部活动轴接撑杆组合件;所述撑杆组合件包括平行四连杆机构22及与其活动轴接的顶部工作端221;在所述平行四连杆机构22的上下端部分别活动轴接卡块222;所述平行四连杆机构22压缩幅度足以确保卡块222到达顶推阀瓣组件内孔壁的位置;所述平行四连杆机构22固定设有弹簧223。
本发明所述等分机构包括拨片24及卡槽23;所述卡槽23均布于卡盘20的圆周边缘处且与拨片24相对应;所述阀瓣组件的两侧经轴承7与压板组件6活动轴接。当然,根据设计需要,等分机构也可采用滚珠弹簧扣的设计思路。
当阀门关闭时,通过手轮9转动阀杆12,阀杆12与阀盖8上方铜螺母10配合产生向下的推力作用在压板组件6上,压板组件6下方设置阀瓣组件,阀瓣组件中的阀瓣5可采用立方多面体结构,压板组件6压紧阀瓣5一面的同时,对称的另一面与阀体的阀口101处组成静密封。当阀门开启时,逆向旋转手轮9,阀杆12升起,压板组件6带动阀瓣组件升起,当需要更换阀瓣的密封面时,提升到特定的高度,转动侧面手轮25,侧杆18带动撑杆组合件卡进多面体阀瓣一侧的凹槽26内,克服拨片24的阻力转动多面体阀瓣至某一角度,更新密封阀瓣的密封面。侧面手轮25下方可设置刻度盘,可以及时查看阀瓣5在阀腔的位置及角度,拨片24固定在压板组件6一侧并且具有弹性,前端卡入卡盘20内的卡槽23内其阻力大于介质的压力,只有当撑杆组合件上的卡块222卡入到阀瓣的凹槽26内且施加给阀瓣足够的力时才能转动。当转动完成后,侧杆18缩回原来位置,弹簧223顶着平行四连杆机构22向内靠近,离开凹槽26的位置。固定多面体阀瓣的压板组件6是上下对分结构,两侧设置轴承方便转动,上沿高度大于多面体的旋转半径。本发明的目的和优点在于需要更新阀瓣时,不需要从管线上拆解,只需要转动一侧的手轮至某一角度就可以完成,具有一台阀门多个阀瓣的特点。
