[0002] Valves are control components in fluid delivery systems and have functions such as locking, regulating, guiding, preventing backflow, stabilizing pressure, diverting or overflowing pressure relief. In winter when the temperature is below zero degrees Celsius, the water accumulated in the valve pipeline will condense into ice, which will not only make the valve unusable, but also cause frostbite and damage to the valve. Therefore, the valve needs to be insulated.

[0003] When insulating the valve, multiple layers of insulation material are wrapped around the outside of the valve. However, in order to ensure the normal operation of the valve, the valve needs to be inspected and maintained regularly. When the valve is inspected, all the insulation materials on the outside of the valve need to be removed. After the valve inspection is completed, the insulation material is re-wrapped on the outside of the valve, which is time-consuming, labor-intensive, and costly. In addition, the existing structure for insulating the valve is relatively simple, and the effect of insulating the valve is low. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution for a valve heat preservation structure: a valve heat preservation structure, including a valve 1, a heat preservation mechanism 2 is arranged outside the valve 1, and the heat preservation mechanism 2 is used for heat preservation of the valve 1;

[0026] The heat preservation mechanism 2 includes a housing assembly, a docking assembly and a heating assembly;

[0028] The housing assembly in the installed state is used to wrap the valve 1;

[0029] The heating assembly is used to provide heat energy to the valve 1.

[0030] Please pay special attention to Figure 4 , the housing assembly includes a first housing 201, a second housing 202, a groove 208, a connection seat 209, a connection shaft 2010 and a torsion spring 2011;

[0031] The first housing 201 and the second housing 202 are detachably connected to the valve 1, the groove 208 is opened inside the first housing 201, the connection seat 209 is fixedly connected to the surface of the second housing 202, the connection shafts 2010 are formed at both ends of the connection seat 209, and the connection shafts 2010 are rotatably connected to the groove 208. Both ends of the torsion spring 2011 are respectively engaged with the connection seat 209 and the groove 208, and the torsion spring 2011 in the twisted state is used to drive the first housing 201 and the second housing 202 to rotate and reset.

[0032] In this embodiment: Rotate the first housing 201 and the second housing 202 away from each other around the connecting shaft 2010. Then, the first housing 201 and the second housing 202 in the state of rotating away from each other squeeze the torsion spring 2011, and the torsion spring 2011 is distorted under force. Then, the first housing 201 and the second housing 202 in the state of rotating away from each other are sleeved outside the valve 1, and then the first housing 201 and the second housing 202 are loosened, so that the torsion spring 2011 in the reset state drives the first housing 201 and the second housing 202 to rotate inward and reset, and the first housing 201 and the second housing 202 in the state of rotating closer to each other are in a closed state.

[0033] Please refer specifically to Figure 2 , the docking assembly includes a bolt seat 203 and a bolt 204;

[0034] The surfaces of the first housing 201 and the second housing 202 are both fixedly connected with bolt seats 203, and the bolt 204 is threadedly connected with the bolt seats 203.

[0035] In this embodiment: Threadedly connect the bolt 204 with the two bolt seats 203 on the surfaces of the first housing 201 and the second housing 202. The bolt 204 in the tightened state docks and installs the first housing 201 and the second housing 202. Then, the first housing 201 and the second housing 202 in the installed state are sleeved outside the valve 1, and the first housing 201 and the second housing 202 in the installed state insulate the valve 1.

[0036] Please refer specifically to Figure 2 , the bolt 204 in the tightened state is used to dock and install the first housing 201 and the second housing 202, and the first housing 201 and the second housing 202 in the installed state are sleeved outside the valve 1.

[0037] In this embodiment: Dock and install the first housing 201 and the second housing 202 through the bolt 204 in the tightened state. Then, the first housing 201 and the second housing 202 in the installed state are sleeved outside the valve 1.

[0038] Please refer specifically to Figure 4 , the heating assembly includes a temperature sensor 207, two rock wool pads 205 and an electric heating wire 206;

[0039] The two rock wool pads 205 are respectively arranged on the inner walls of the first housing 201 and the second housing 202, the two electric heating wires 206 are respectively arranged inside the first housing 201 and the second housing 202, the temperature sensor 207 is fixedly installed on the inner wall of the first housing 201, and the temperature sensor 207 is electrically connected to the two electric heating wires 206 through a controller.

[0040] In this embodiment: When the receiving end of the temperature sensor 207 detects that the surrounding environment temperature is low, the transmitting end of the temperature sensor 207 transmits a signal to the controller, and the controller controls the two electric heating wires 206 to operate. The two electric heating wires 206 in the operating state provide heat energy inside the first housing 201 and the second housing 202 in the closed state, thereby heating and raising the temperature of the surface of the valve 1. And because the heat conduction coefficient of the rock wool pad 205 is low, the rock wool pad 205 can keep warm the inside of the first housing 201 and the second housing 202 in the closed state, thus effectively improving the heat preservation effect of the valve 1.

[0041] Please refer specifically to Figure 3 , seals 3 are provided at the docking joints of the first housing 201 and the second housing 202, and the seals 3 are used to improve the sealing performance of the first housing 201 and the second housing 202 in the installed state.

[0042] In this embodiment: When the first housing 201 and the second housing 202 are docked and installed, the two seals 3 provided at the docking joint of the first housing 201 and the second housing 202 are closely attached, so that the seals 3 can improve the sealing performance of the first housing 201 and the second housing 202 in the installed state.

[0043] Working principle: First, rotate the first housing 201 and the second housing 202 away from each other with the connecting shaft 2010 as the center. Then, the first housing 201 and the second housing 202 in the state of rotating away from each other squeeze the torsion spring 2011, and the torsion spring 2011 is distorted by the force. Then, sleeve the first housing 201 and the second housing 202 in the state of rotating away from each other outside the valve 1. Then loosen the first housing 201 and the second housing 202, so that the torsion spring 2011 in the reset state drives the first housing 201 and the second housing 202 to rotate inward and reset. The first housing 201 and the second housing 202 in the state of rotating closer to each other are in a closed state. At this time, use the bolt 204 to be threadedly connected with the two bolt seats 203 on the surfaces of the first housing 201 and the second housing 202. The bolt 204 in the tightened state docks and installs the first housing 201 and the second housing 202. Then, the first housing 201 and the second housing 202 in the installed state are sleeved outside the valve 1. The first housing 201 and the second housing 202 in the installed state keep the valve 1 warm and are convenient for disassembling and installing the first housing 201 and the second housing 202;

[0044] When the receiving end of the temperature sensor 207 detects that the ambient temperature is relatively low, the transmitting end of the temperature sensor 207 transmits a signal to the controller, and the controller controls the two electric heating wires 206 to operate. The two electric heating wires 206 in the operating state provide heat energy inside the closed first housing 201 and the second housing 202, thereby heating and raising the temperature of the surface of the valve 1. Moreover, since the heat conduction coefficient of the rock wool pad 205 is low, the rock wool pad 205 can keep the inside of the closed first housing 201 and the second housing 202 warm, thus effectively improving the heat preservation effect of the valve 1.
