一种组合式分体内衬闸阀
本技术涉及闸阀设备领域,尤其涉及一种组合式分体内衬闸阀体。
技术介绍
目前,闸阀应用比较广泛,种类繁多,用途在于通过闸阀来控制阀体管道中介质的流量。现有的陶瓷闸阀是在其阀体内设有一整体陶瓷件来使其具有良好的耐磨性,但是其整体陶瓷件安装较困难,制造成本高,并且安装有偏差后使用过程中受力不平衡容易破碎,造成闸阀使用寿命缩短,并且由于现有的阀体内均为整体,一旦出现损坏时,阀体即需要整体更换。
技术实现思路
本技术的目的在于,克服现有技术的不足之处,提供一种可根据不同工况调整内部工件的组合式分体内衬闸阀,且在内部工件出现损坏时,可由用户自行更换内部工件,降低了使用成本。一种组合式分体内衬闸阀,包括闸板和阀体,在阀体上设置有闸板,所述闸板与驱动机构连接,由驱动机构控制闸板的运动,所述阀体上设有闸板入口,其特征在于,所述阀体内腔的内壁上设有与阀体内壁相契合的固定夹层,所述固定夹层的内壁上设有至少一个挡块,固定夹层内套设有一套芯,所述套芯的外壁上设有与挡块相对应的挡块凹槽,所述阀体与固定夹层及套芯分别为空心管道状,所述固定夹层及套芯上设有与阀体上闸板入口对应的插 ...
