Abstract

The present invention relates to a drainage plug, which intermittently fits the fitting portion of the plug body and the outer cylinder to form a gap. It does not require multiple drainage outlets in the past, and does not require a sand-cutting cover. It has good drainage performance and water interception. The stopper is detachably fitted on the lower mandrel and has a drainage path, and integrates a water-cutting gasket covering the front end and a drainage gasket that is spaced and opposite to the water-cutting gasket, and the water-cutting gasket and drainage gasket are The gasket is easy to replace and there is no intermediate water leakage. The water-cutting gasket consists of a protruding part covering the central part of the front end and a peripheral part connected at right angles to the protruding part. The part of the peripheral part that is connected to the protruding part has a U-shaped cross-section. The outer surface of the protruding portion has a partially R-shaped groove, and the drain gasket has a groove with a U-shaped cross section at the peripheral portion that is in contact with the protruding portion.

Description

Technical field [0001] The present invention relates to a drain hydrant for a water channel system. Background technique [0002] In the waterway system in the cold zone, the drainage hydration such as antifreeze is connected to the water channel. An example of a conventional drain hydrant will be described with reference to Fig. 11. The figure is a front cross-sectional view of the drainage plug (hereinafter referred to as an unfroken water) described in Patent Document 1. The handle 110 of the upper and lower drive operating lever 112 is mounted on the upper portion of the drain. The handle 110 is connected to the operating lever 112 in the inner portion of the drain hydrant 107, and the operating rod 112 is interposed with a down-axis of the lower end shaft in which it is connected to the lower end. The drain suppression has the following characteristics, to prevent the intermediate drain at the time of the valve switching, and the drainage hole is performed after the entire p...
