Claims

[Claims for Utility Model Registration] 1. A drain faucet body having a valve piece inside, and a mantle tube connected to a cylindrical connecting part of the main body at the lower end and having a valve piece operating device mounted at the upper end, In an antifreeze water drain valve that operates a valve piece via a spindle inserted into a mantle pipe to allow water to flow to a branch pipe, stop water, and drain water from the branch pipe, at least the main body and the mantle pipe are connected to each other. A cylindrical cover body that fits over the mantle tube from the cylindrical joint part of the main body at the connection part with the mantle pipe, and a cylindrical cover body disposed between the cover body and the mantle pipe and/or the cylindrical joint part. An antifreeze drain plug characterized by having a sealing member. . 2. The antifreeze water drain plug according to claim 1, wherein the cover body is an integral heat-shrinkable body that extends from the mantle tube to the cylindrical connecting portion of the main body and is coated and heat-shrinked on the outer periphery thereof. An antifreeze drain plug characterized by comprising a sex tube. 3. The antifreeze drain plug according to claim 2, wherein the sealing member is disposed on the cylindrical connecting portion of the main body and/or on the outer tube, and the sealing member is disposed on the cylindrical connecting portion and the heat-shrinkable tube. and/or between the mantle tube and the heat-shrinkable tube, the elastic member being compressed by the contraction force of the heat-shrinkable tube. Antifreeze water drain valve. 4. The antifreeze drain plug according to claim 2, wherein the heat-shrinkable tube has a hot melt type material on its inner periphery at least in a portion extending over the connecting portion and onto the mantle tube and the cylindrical connecting portion. An antifreeze drain plug characterized by being coated with adhesive. 5. In the antifreeze drain plug according to claim 1, the cover body is made of a plastic molded product, and the cover body, the mantle tube, and the cylindrical connecting portion are bonded using an adhesive. Features an antifreeze drain plug. 6. In the antifreeze water drain plug according to claim 4 or 5, a heat-shrinkable tube extending from near the upper end of the mantle tube beyond the connecting portion to cover the cylindrical connecting portion is covered, and the heat-shrinkable tube is An antifreeze water drain plug, characterized in that the cover body is placed on top of the cover body, and the cover body, the heat shrinkable tube, and the cylindrical connecting portion are adhered by the adhesive.
