The utility model relates to a special packing gland for a water pump, which comprises a ring-shaped cover plate and a baffle plate. The cover plate is provided with a number of first installation holes, a number of second connection holes are provided on the sleeve, the end of each second connection hole is provided with a ring-shaped baffle ring, the side of the baffle plate is provided with a fixed rod, and a number of barbs are installed on the fixed rod. After the packing is in place, the utility model places the sleeve between the stuffing box and the pump shaft and compresses the packing. After the cover plate is fastened by bolts, the baffle plate is pushed to drive the fixed rod to move towards the packing, so that the fixed rod and several barbs are inserted into the packing, and the packing is connected with the retaining ring through the fixed rod and several barbs. When the packing is replaced, the cover plate is disassembled, and the sleeve is pulled out during the extraction process The sleeve pulls out the packing through the retaining ring, the fixed rod and several barbs. The packing takes out for a short time, and the inner wall of the valve rod and the stuffing box will not be scratched in the process of taking out. The fixed rod and several barbs also play the role of compressing the packing evenly, so as to prevent the packing close to the gland from being pressed too tightly.
【技术实现步骤摘要】
一种水泵专用填料压盖
本技术涉及水泵配件领域,具体地说是一种水泵专用填料压盖。
技术介绍
为了封闭泵壳与泵轴之间的空隙,不让泵内的水流流到外面来也不让外面的空气进入到泵内,需要在泵壳与泵轴之间的空隙内放置填料,并通过填料压盖将填料压紧。由于水泵工作时,填料与泵轴会产生摩擦,磨损较大,隔一段时间就需要更换。而目前填料一般采用人工通过铁丝钩取出,钩取填料时很容易划伤阀杆及填料函内壁。
技术实现思路
为解决上述问题,本技术提供一种水泵专用填料压盖,其能够便于取出填料,避免取出过程中划伤阀杆及填料函内壁。本技术为实现上述目的,通过以下技术方案实现:一种水泵专用填料压盖,包括环形的盖板和挡板,盖板侧部开设环形的凹槽,凹槽内设置套筒的一端,盖板上开设数个第一安装孔,套筒上开设数个第二连接孔,第一安装孔与对应的第二连接孔孔径相同且中心线重合,每个第二连接孔端部设置环形的挡环,挡板位于第二连接孔内,挡板能够沿第一安装孔和第二连接孔滑动,挡环能够阻挡挡板,挡板侧部安装固定杆,固定杆上安装数个倒刺,固定杆和数个倒刺能够穿 ...
