Valve with anti-freezing function

Abstract

The invention discloses a valve with an anti-freezing function. The valve with the anti-freezing function comprises a valve main body and a first cylinder body; the first cylinder body is connected with one side of the valve main body in a through manner; a first open groove is formed in one side of the top end of the first cylinder body; a connecting cylinder is arranged on one side of the firstcylinder body; an annular heat conducting block is embedded in the internal side of the first cylinder body and the internal side of the connecting cylinder; and a second open groove is formed in oneside of the top end of the connecting cylinder. According to the valve with the anti-freezing function, by using an annular tube and an electric heating wire, the second cylinder body can be heated sothat one part, in the second cylinder body, of the valve main body can be heated; through the adoptions of a limiting column and a limiting hole, the heat on the annular tube can be transmitted intothe connecting cylinder and the first cylinder body; under the coordination of the annular heat conducting block, parts, in the first cylinder body and the connecting cylinder, of the valve main bodycan be heated so as to prevent the valve main body from being unable to work properly due to being frozen at a lower temperature.

Description

technical field [0001] The invention relates to a valve, in particular to a valve with antifreeze function. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex There are various types and specifications of valves used in the automatic control system. [0003] At present, the existing valves generally do not have the antifreeze function. When the temperature is low, the valves are frozen and cannot ...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing valves generally do not have antifreeze function. When the temperature is low, the valve is frozen and cannot be used normally, causing inconvenience to users and low practicability.
