Abstract

The invention discloses an anti-freezing control valve comprising a valve body, electric heating tubes and a non-return structure, and the valve body is provided with an input end and an output end; containing cavities are formed in the pipe walls of the input end and the output end, and a drainage through hole is formed in the bottom of the valve body; a valve seat is connected between the input end and the output end, and the drainage through hole is located below a vertical through hole; a first sealing plug used for opening and closing the valve seat is installed in the valve body, and a magnetic block is installed on the side, facing the drainage through hole, of the first sealing plug; the electric heating tubes are arranged in the containing cavities in a penetrating manner; the non-return structure comprises a second sealing plug embedded in the drainage through hole, a limiting plate supported at the bottom of the second sealing plug, and a supporting rod installed at the exterior of the valve body; the limiting plate is detachably installed on the supporting rod, and the second sealing plug is provided with an electromagnet arranged oppositely to the magnetic block; and the limiting plate is provided with a power source, and the power source is connected with the electromagnet. According to the anti-freezing control valve, the problem that the interior of the valve is prone to freezing at lower temperature, and consequently normal use of a pipeline passage is affected is solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an antifreeze control valve. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. [0003] Some valves are used outdoors. When the outdoor temperature is low, it may cause the valve to freeze and affect the normal use of the pipeline. Contents of the invention [0004] In order to overcome the defects in the prior art, an antifreeze control valve is provided to solve the problem that the inside of the valve is easy to freeze when the temperature is low, which affects the normal use of the pipeline passage. [0005] In order to achieve the above purpose, an antifreeze control valve is provided, including: [0006] The valve body, the valve body has an input end and an output end, and...
