Abstract

The invention discloses a valve with an anti-freezing function, and relates to the technical field of valves, the valve comprises a valve body, a water inlet pipe and a water outlet pipe are respectively arranged at two ends of the valve body, an anti-backflow mechanism and an anti-freezing mechanism are arranged on the inner side of the valve body, and the anti-backflow mechanism comprises an anti-backflow movable plate. Through cooperation of the backflow-preventing movable plate, the water guiding plate, the sealing clamping groove, the soft connecting push rod, the sliding groove and the elastic backflow-preventing assembly, water flow pushes the backflow-preventing movable plate to rotate towards one side along the inner wall of the valve body, and the sealing performance of the connecting position of the backflow-preventing movable plate and the inner wall of the valve body is enhanced through the arrangement of the water guiding plate; meanwhile, one end of the anti-backflow movable plate drives the soft connecting push rod to slide towards one side along the inner wall of the sliding groove, and through the elastic reset effect of the elastic anti-backflow assembly, when the water pressure is higher than the elastic acting force of the elastic anti-backflow assembly, the end of the anti-backflow movable plate can be separated from the sealing clamping groove to form a proper gap.

Description

technical field [0001] The invention relates to an antifreeze valve, and relates to the technical field of valves, in particular to a valve with antifreeze function. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. Valves used in fluid control systems, from the simplest shut-off valve to various valves used in extremely complex automatic control systems, have a wide variety and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. When the temperature is too low, the valve may be frozen, thus affecting the user's control of the valve. [0003] The following problems exist for the prior art: [0004] 1. The existing valve with antifreeze function does not have the anti-backflow set...
