Sluice valve rod protection structure

一种闸阀阀杆保护结构

Abstract

The invention provides a sluice valve rod protection structure which comprises a valve rod. The valve rod is provided with a hand wheel. The end, on the upper portion of the hand wheel, of the valve rod is provided with a sleeve with the sealed upper end in a sleeving mode. The length of the sleeve is the length of the portion, on the upper portion of the hand wheel, of the valve rod when a valve is completely opened. One side of the sleeve is provided with an oiling hole. The oiling hole is a long hole formed in the axial direction of the valve rod. The sleeve is provided with an internal thread. According to the sluice valve rod protection structure, the end, on the upper portion of the hand wheel, of the valve rod is provided with the sleeve with the sealed upper end in the sleeving mode, rainwater and dust can be prevented from entering the valve rod effectively, and thus lubricating oil (grease) in the valve rod is prevented from being lost.
本发明所述一种闸阀阀杆保护结构,包括阀杆,所述阀杆设有手轮,所述阀杆在手轮的上部一端套有上端封闭的套管,而且套管的长度为阀门全启时阀杆在手轮上部的长度,套管一侧开有加油孔,加油孔为沿所述阀杆轴向设置的长孔,套管开有内螺纹。本发明所述一种闸阀阀杆保护结构,阀杆在手轮的上部一端套有上端封闭的套管,可有效防止雨水及灰尘进入,从而防止阀杆内润滑油(脂)流失。
