Description
Technical Field
[0001] This utility model relates to the field of ball valve technology, specifically to a heat-insulating ball valve assembly. Background Technology
[0002] A ball valve is a type of rotary valve. Its core component is a ball with a circular through-hole, which is installed inside the valve body. By rotating the valve stem, the ball rotates within the valve body. When the through-hole of the ball is aligned with the direction of the pipeline, the valve is open, and fluid can pass through smoothly. When the through-hole of the ball is perpendicular to the direction of the pipeline, the valve is closed, and the fluid is cut off. Ball valves have advantages such as compact structure, good sealing performance, convenient operation, rapid opening and closing, and low fluid resistance. They are widely used in various industrial and civil pipeline systems and are suitable for various media such as water, gas, and oil. Ball valves require insulation primarily to prevent the internal medium from solidifying, crystallizing, or increasing in viscosity at low temperatures, which could affect the valve's normal operation and sealing performance. Insulation maintains the flow state of the medium, ensuring that the valve can still open and close flexibly under low-temperature conditions, while reducing heat loss and improving energy efficiency. This is especially important for pipeline systems that transport media that are prone to solidification, crystallization, or are temperature-sensitive. To achieve heat preservation of ball valves, existing technologies often involve wrapping an electromagnetic heating coil around the outside of the ball valve to prevent the medium between the valve disc and seat from solidifying, crystallizing, or increasing in viscosity at low temperatures. However, during later use, the frequent operation of the ball valve causes mechanical vibration, which can lead to the electromagnetic heating coil gradually loosening. This loosening can cause the heating coil to shift, resulting in uneven heat distribution, affecting the heat preservation effect, and may even damage the heating coil itself, reducing its service life and reliability. Therefore, a heat-insulating ball valve assembly is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A heat-insulating ball valve assembly includes a ball valve body 1. A first heat-insulating component 2 and a second heat-insulating component 5 are sleeved on the outside of the ball valve body 1. The first heat-insulating component 2 and the second heat-insulating component 5 are fixed together by bolts 4. A heating component 3 is fixedly connected inside the first heat-insulating component 2. The first heat-insulating component 2 includes a heat-insulating shell 21. An insertion hole 23 is opened on the inner side of the heat-insulating shell 21. A rubber pad 26 is fixedly connected to the front end of the heat-insulating shell 21. A wiring channel 27 and an adhesive hole 28 are opened on the inner side of the rubber pad 26. The heating component 3 includes an integrated controller 31. A wire 32 is fixedly connected to the top of the integrated controller 31. The wire 32 is fixedly connected to a heating wire 33. Electrical terminals 34 are fixedly connected to both ends of the heating wire 33. The heating wire 33 is inserted into the insertion hole 23. The electrical terminals 34 are fixedly connected to the adhesive hole 28 opened in the rubber pad 26 by adhesive.
[0017] As a further implementation of this solution, the insulation shell 21 and the second insulation component 5 are both sleeved on the outside of the ball valve body 1. There are gaps between the inner side of the insulation shell 21 and the inner side of the second insulation component 5 and the outer side of the ball valve body 1. Through the above arrangement, this structural design allows the insulation shell 21 and the second insulation component 5 to better adapt to the shape of the ball valve. As a further implementation of this solution, the upper and lower ends of the insulation shell 21 are fixedly connected with fixing seats 22. The structure of the insulation shell 21 is the same as that of the second insulation component 5. The fixing seats 22 of the second insulation component 5 and the fixing seats 22 of the insulation shell 21 are fixed by bolts 4. Through the above arrangement, the connection between the insulation shell 21 and the second insulation component 5 can be made more secure, avoiding the loosening of components due to mechanical vibration, thereby ensuring the stability and reliability of the insulation device. As a further implementation of this solution, the heating wire 33 and the electrical terminal 34 are fixed inside the second insulation component 5. The electrical terminal 34 inside the second insulation component 5 is in contact with the electrical terminal 34 inside the first insulation component 2. Through the above arrangement, this design allows the heating element heating wire 33 and the electrical terminal 34 to fit better with the insulation component, ensuring that heat can be evenly transferred to the interior of the insulation component, further improving the insulation effect, while reducing heat waste and improving energy utilization efficiency. As a further implementation of this solution, a first rubber sealing ring 24 is fixedly connected to the inner side of the insulation shell 21, and a second rubber sealing ring 25 is fixedly connected to the upper part of the insulation shell 21. The insulation shell 21 is attached to the outer side of the ball valve body 1 through the first rubber sealing ring 24 and the second rubber sealing ring 25. The rubber pad 26 fixed to the insulation shell 21 is attached to the rubber pad 26 fixed to the second insulation component 5, and the two second rubber sealing rings 25 are attached to each other. Through the above settings, a good sealing effect is formed to prevent external cold air from entering, further improve the insulation performance, maintain the flow state of the medium, and ensure that the valve can still be opened and closed flexibly under low temperature conditions. As a further implementation of this solution, the integrated controller 31, wire 32, heating wire 33 and electrical terminal 34 are electrically connected. The heating wire 33 has an arc-shaped structure. Through the above settings, the electrical connection design ensures that the heating element can work stably. The arc-shaped structure of the heating wire 33 can better fit the shape of the ball valve, so that the generated heat can be distributed more evenly, further improving the heat preservation effect and reducing energy waste. At the same time, the arc-shaped structure also helps to improve the service life and reliability of the heating element.
[0018] Workflow: During installation, both the insulation shell 21 and the second insulation component 5 are made of polystyrene foam. The insulation shell 21 and the second insulation component 5 are lightweight, have good thermal insulation properties, and are manufactured using 3D printing technology. They require insertion holes 23 for inserting the heating wire 33. The insulation shell 21 is then fitted onto the outside of the ball valve body 1, ensuring that both the second rubber sealing ring 25 and the first rubber sealing ring 24 are in close contact with the outside of the ball valve body 1. Then, the second insulation component 5 is sleeved on the outside of the ball valve body 1, so that the rubber pad 26 fixed at the rear end of the second insulation component 5 and the rubber pad 26 fixedly connected at the front end of the insulation shell 21 are aligned and fit together. At the same time, the through holes of the fixing seat 22 fixed to the second insulation component 5 and the fixing seat 22 fixed to the insulation shell 21 are aligned with each other. The insulation shell 21 and the second insulation component 5 are fixedly installed by bolts 4. At this time, the electrical terminal 34 on the second insulation component 5 and the electrical terminal 34 on the insulation shell 21 are electrically connected. When insulating the ball valve body 1, the first rubber sealing ring 24 on the second insulation component 5 and the first rubber sealing ring 24 on the insulation shell 21 are bonded together, and at the same time bonded to the outside of the ball valve body 1. In addition, the two second rubber sealing rings 25 are bonded to the ball valve body 1, and the multiple rubber pads 26 at the upper end are bonded to each other. In this way, the space between the insulation shell 21 and the second insulation component 5 and the ball valve body 1 is sealed to prevent external cold air from entering. In addition, the insulation shell 21 is used to achieve the function of insulating and protecting the ball valve body 1. In order to ensure the constant temperature performance of the insulation shell 21 and the second insulation component 5, it is necessary to periodically energize the wire 32 and the heating wire 33 through the integrated controller 31 to achieve the purpose of heating the inside of the insulation shell 21 and the second insulation component 5. The embedded design of the heating wire 33 can keep most of the heat generated inside the second insulation component 5 and the first insulation component 2, reducing energy waste. Based on the above principles, the device changes the traditional method of heating and heat preservation by wrapping an electromagnetic heating coil around the outside of the ball valve body 1. It can keep the position of the electromagnetic heating coil from shifting due to mechanical vibration even when the ball valve body 1 is frequently operated, thus ensuring the stability and reliability of heating the ball valve body 1.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
