Open-closed self-release anti-freezing stop valve

Abstract

The invention discloses an open-closed self-release anti-freezing stop valve. The open-closed self-release anti-freezing stop valve comprises a pipe main body, wherein a water outlet, a water discharge opening and a water inlet which communicate with a passage in the pipe main body are formed in the pipe main body, the water discharge opening and the water inlet are located below the ground, the water outlet is located above the ground, and the water discharge opening is located above the water inlet. The open-closed self-release anti-freezing stop valve further comprises a water discharge valve blocking piece used for blocking the water discharge opening, an upper water blocking piece used for blocking the water inlet and an adjusting piece used for controlling the water discharge valve blocking piece and the upper water blocking piece, wherein when the adjusting piece rotates in the first direction, the water discharge valve blocking piece is away from the water discharge opening, the water discharge opening is opened, and the upper water blocking piece seals the water inlet; and when the adjusting piece rotates in the second direction, the water discharge valve blocking piece seals the water discharge opening, and the upper water blocking piece opens the water inlet. Water or fluid in the passage of the pipe main body can be discharged through the water discharge opening, and the pipe main body cannot be frozen in winter; and due to the fact that no water exists in the pipe main body, the pipe main body cannot be blocked and is not easy to be frozen and cracked.

Description

technical field [0001] The present application relates to the field of antifreeze technology for water pipes, and more specifically, relates to an open and close self-releasing antifreeze gate. Background technique [0002] In the northern part of my country, after entering winter, the temperature drops below 0°C, and when the end of the water supply system is connected to the user, the phenomenon of freezing and cracking of the water pipes still occurs from time to time, especially the water pipes or solar pipes distributed outdoors often freeze. It brings inconvenience to the production and life of the masses; especially when carrying out fire-fighting water supply, due to the low temperature environment in winter, the water source cannot be used urgently in time, resulting in the failure of effective control of the primary fire source and causing serious losses to human beings. And in rural areas and in the wild, people mainly rely on water pipes for water supply. The wate...
