Claims

[Claims for Utility Model Registration] 1. A mantle pipe having a main body, an inlet, a water supply inlet, and a drain, and a device installed in the main body of the mantle to control the water flow state, water stoppage, and drainage. and a valve piece that can be switched between the two states, the inlet is formed in a substantially cylindrical shape, and a valve seat is formed in a communicating portion with the main body, and the inlet is capable of contacting the valve seat. In an antifreeze drain valve that receives a movable valve body, a cylindrical socket for connecting upstream piping to the inlet is attached to the inlet, and the valve body can come into contact with the socket. An antifreeze drain valve characterized by forming a valve seat. 2. The antifreeze drain plug according to claim 1, wherein the valve body has a sliding part and a valve seat abutting part formed on both sides of the sliding part, and the inflow port includes: An antifreeze drain plug characterized in that a guide portion is formed to guide the sliding portion. 3. The antifreeze water drain plug according to claim 2, wherein the valve body includes a first and a second member separated at the sliding portion, and the first and second members are connected to the valve body. An antifreeze drain plug characterized in that the first and second members are assembled to each other so as to be movable relative to each other in the axial direction, and further include a biasing member that urges the first and second members apart from each other. 4. The antifreeze drain plug according to claim 3, wherein a recess is formed in a surface of at least one of the first and second members relative to the other member, and the first and second members are assembled to each other. The antifreeze water drain plug is characterized in that the recess forms a cavity within the valve body in the closed state, and the biasing member is housed in the cavity.
