Description

Technical Field

[0001] The utility model relates to the technical field of electric ball valves, in particular to a regulating type on-off electric ball valve. Background Technique

[0002] An electric ball valve is a valve that rotates around the axis of the valve stem in this form of movement of the valve flap. The change of the seat port is in direct proportion to the stroke of the valve flap. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of fluids.

[0003] The publication number CN219198197U discloses an electric ball valve, which includes a valve body and a box body. The box body is located above the valve body. A valve core is rotatably clamped in the valve body. The valve core is used to control the on-off of the flow. One side of the valve core close to the box body is fixedly provided with a connecting column. The connecting column rotates to drive the valve core to rotate in the valve body, so as to control the on-off. One end of the connecting column away from the valve core is fixedly provided with a first fixing plate. A first rotating rod is rotatably inserted in the box body. The end of the first rotating rod away from the box body is fixedly provided with a second fixing plate. The second fixing plate is inserted with screws distributed in an array. The first fixing plate and the second fixing plate are fixed by screws and nuts, so that the box body and the valve body are fixedly connected, avoiding the trouble of disassembly when the device fails or needs maintenance, so as to achieve the purpose of convenient disassembly and maintenance. However, in a low-temperature environment, the water flow inside the valve body of the existing electric ball valve is prone to freezing. This phenomenon is mainly due to the rapid decrease in the temperature of the water flow at low temperature. When it reaches the freezing point, the water flow will gradually condense into ice, resulting in difficult or ineffective valve operation. Due to icing, the valve core cannot rotate smoothly, thus unable to effectively control the on-off of the flow. This not only affects the basic function of the electric ball valve, but also may cause the stagnation or failure of the entire industrial automation control system. Therefore, improvement is needed.

[0029] Working principle: The rotation of the sphere 5 can be controlled by the actuator 4, thereby adjusting the opening and closing of the valve body 1. When used in low-temperature weather, the micro motor 6 can drive the worm 7 to rotate. Subsequently, the worm 7 can drive the worm wheel 9 meshing with it to rotate. Then, the worm wheel 9 can drive the rotating rod 8 to rotate. Next, the rotating rod 8 can drive the stirring shaft 10 to rotate. Then, the stirring shaft 10 can drive the stirring blades 11 to rotate. At this time, the water flow at the sphere 5 can be stirred by the stirring blades 11, which can reduce the probability of water flow freezing and achieve the anti-freezing effect. Through the design of the stirring blades 11 in the present utility model, the water flow at the sphere 5 can be effectively stirred, reducing the probability of water flow freezing. Especially when used in low-temperature weather, the water flow inside the valve body 1 can be significantly prevented from freezing. By using the micro motor 6 to drive the worm 7 and the worm wheel 9 to rotate, the automatic stirring function is realized without manual intervention, improving the operation convenience and efficiency. Through the introduction of the stirring mechanism, the continuous and stable operation of the valve body 1 can be maintained under low-temperature conditions, avoiding valve blockage or damage caused by icing and ensuring reliability. During the rotation of the worm 7, the friction column 17 can be driven to rotate synchronously. At this time, the friction column 17 can rub against the friction plate 16, and heat can be generated during the rubbing process, thereby heating the heat conduction plate 18. At this time, the heat conduction plate 18 can heat the water in the valve body 1, which can further reduce the probability of water flow freezing and further protect the valve body 1. At the same time, under the pulling force of the tension spring 15, the tension spring 15 can pull the round block 14 to move. Then, the round block 14 can drive the long rod 13 to move. Next, the long rod 13 can drive the friction plate 16 to move, which can make the friction plate 16 fit more closely with the friction column 17, thereby improving the heat generation effect. In the present utility model, heat is generated by the friction between the friction column 17 and the friction plate 16 to heat the heat conduction plate 18, thereby heating the water in the valve body 1, further reducing the probability of water flow freezing, effectively preventing the water inside the valve body 1 from freezing under low-temperature conditions. At the same time, during the rotation of the worm 7, the friction column 17 synchronously drives the friction plate 16 to generate heat, without the need for additional electric heating devices or manual operations, realizing the automatic heating function, avoiding the leakage problem, improving the safety. At the same time, it can not only prevent the water flow from freezing, but also protect the valve body 1, extend its service life, and reduce valve blockage or damage caused by icing. And the pulling force of the tension spring 15 drives the friction plate 16 to fit more closely with the friction column 17, further improving the friction heat generation effect and ensuring that the heating efficiency and effect are more significant.
