Description

Technical Field

[0001] The utility model relates to the technical field of air valve heat preservation equipment, in particular to an air valve actuator heat preservation device. Background Art

[0002] At present, during the construction process, the air valve will be equipped with a corresponding actuator. In the system that needs to be insulated, the insulation of the protruding actuator on the air valve body is generally simply covered with insulation cotton. It is easy to cause the actuator to interfere with the insulation cotton, resulting in the mechanism being unable to rotate flexibly, affecting the subsequent use function.

[0003] During duct construction, damper actuators on systems requiring insulation also require insulation. Centrifugal glass wool and rubber-plastic wool are commonly used to simply cover these. However, this covering method can cause the damper's rotating handle to become stuck in the insulation, making it difficult to rotate and affecting its usability. Typically, the insulation is cut and placed around the outside of the actuator, creating a space to accommodate it. This method makes the actuator inconvenient to use, requiring the insulation to be removed before use. Furthermore, the insulation cannot be effectively secured to the actuator by gluing or welding steel nails, which can lead to insecure insulation at the actuator.

[0004] How to solve the above technical problems is the subject faced by this utility model. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to clearly illustrate the technical features of this solution, the solution is described below through specific implementation methods.

[0033] See also Figures 1 to 6 As shown, this embodiment is a heat preservation device for an air valve actuator, comprising an upper shell 1, a lower shell 2 and a handle shell 3. The upper shell 1 and the lower shell 2 have the same shape, both are rectangular bodies, and respectively include an upper back plate 101 and a lower back plate 201. Side plates are provided on both sides of the upper back plate 101 and the lower back plate 201. The upper back plate 101 is connected to upper side plates 102 perpendicular to it on both sides, and the lower back plate 201 is connected to lower side plates 202 perpendicular to it on both sides. The top of the upper back plate 101 is connected to a top plate 103 perpendicular to it, and the bottom of the lower back plate 201 is connected to a bottom plate 203 perpendicular to it. The upper shell 1 and the lower shell 2 are fitted with the air valve actuator and are located on the outside of the air valve actuator. Axial holes 5 are provided at the opposite edges of the upper back plate 101 and the lower back plate 201. The two axis holes 5 are semicircular and form a full circle relative to each other. The handle shaft 7 of the air valve actuator passes through the two axis holes 5. Circular fixing grooves 6 are provided on the upper back plate 101, the top plate 103, the lower back plate 201 and the bottom plate 203. The fixing grooves 6 are connected with insulation nails. The upper shell 1 and the lower shell 2 are provided with fixing holes 4. Fixing screws pass through the fixing holes 4 to connect the air valve body. The two upper side plates 102 and the two lower side plates 202 are respectively fixedly connected with fixing plates 401. Several fixing holes 4 are provided on the fixing plate 401. The fixing plate 401 is parallel to the upper back plate 101. Several threading holes 204 are provided on the bottom plate 203 of the lower shell 2.

[0034] The handle shell 3 is connected to the handle of the air valve actuator. The handle shell 3 includes two symmetrical shells. The two handle shells 3 are connected by adhesive. Roller holes 301 are opened on the opposite sides of the two handle shells 3. The two roller holes 301 are both semicircular. When the two shells are connected, they form a full circle. The handle roller 701 of the air valve actuator passes through the roller hole 301.

[0035] The upper shell 1 , the lower shell 2 and the handle shell 3 are all made of galvanized steel plates, and thermal insulation cotton is pasted on the outside of the upper shell 1 , the lower shell 2 and the handle shell 3 .

[0036] During actual use of the present invention, the upper and lower housings 1 and 2 completely enclose the damper actuator body. The shaft holes 5 of the upper and lower housings 1 and 2 mate with the handle shaft 7. Fixing screws are then inserted through the fixing holes 4 of the upper and lower housings 1 and 2 to secure the damper body. At this point, the upper and lower housings are completely secured. The two shells of the handle housing 3 are then assembled with the handle, with the handle roller 701 inserted through the roller hole 301 of the housing. The two shells are clamped together at the handle roller 701 and glued together. The assembled handle housing 3 now allows the handle to rotate about the handle shaft 7, ensuring proper operation of the valve body. Once the housings are installed, insulation can begin. Cut the insulation foam into appropriate shapes, tailored to the shapes of the damper actuator body and handle housing, and secure them to the housing and handle housing. Align the insulation pins with the housing insulation fixing points, i.e., the fixing slots 6. This completes the damper actuator insulation.
