Abstract

The invention provides a self-heating control valve. A rotating mechanism is connected to the top end of a valve needle in a threaded mode, and a plurality of heating plates can be connected to the outer wall of the valve needle in an inserted mode. The self-heating control valve has the advantages that solar energy is used for heating the valve needle to prevent internal water from freezing in winter, the heating plate adopts an inserting-connecting mode, and the operation is simple.

Description

technical field [0001] The invention belongs to the field of control valves, in particular to a self-heating control valve. Background technique [0002] The existing drain valve cannot be used in a low-temperature environment. When the temperature is lower than 0°C, the water in the drain valve will freeze, so that the valve core in the drain valve cannot work normally. Insulation cotton or pipe fittings of insulation material are usually used, but the effect is limited. Contents of the invention [0003] In view of this, the present invention aims to propose a self-heating control valve, which can solve the above technical problems. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A self-heating control valve, including a bracket, a valve seat and a valve needle that cooperate with each other. The valve needle is provided with a water passage, and the position near the bottom of the valve needl...
