Abstract

The invention relates to a dewatering stopper, which makes the stopper body and interlocking part of the outer tube perform discontinuous interlocking to form clearance, without bygone many dewatering ports and cutting sand cap to obtain good drainability. The water cutoff top which freely fits into a lower spindle and has a drainage ditch and a damming gasket for covering the front end of it andan opposite draining gasket with a distance from the said damming gasket are formed in one body. The replacement of damming gasket and draining gasket is easy and without middle leakage. The said damming gasket is composed of projection for covering the center of the front end and perimeter right angle jointed with the projection. A slot with section of n-shape is at the conterminous part of projection and perimeter. The outer side of the projection is partly with R section and the draining gasket has a slot with section of n-shape at the perimeter adjacent to the projection.

Description

technical field [0001] This invention relates to drain cocks for waterway systems. Background technique [0002] In waterway systems in cold regions, drain cocks, etc. for anti-freezing are connected to waterway pipes. An example of a conventional drain cock will be described with reference to FIG. 11 . The figure is a front cross-sectional view of a drain cock (herein referred to as a non-freezing water cut-off cock) described in Patent Document 1. FIG. A handle 110 for driving an operating rod 112 up and down is mounted on the upper portion of the drain cock. The handle 110 is connected to the operating rod 112 inside the drain cock via the upper spindle 107, and the operating rod 112 operates the drain cock main body through the lower spindle connected to the lower end thereof. The drain plug has the following characteristics. In order to prevent intermediate drainage when the valve is switched, the difference in the elastic force of the stopper spring 103 and the coil...
