Description

Technical fields:

[0001] This invention relates to the field of thermal insulation technology for valves, equipment, etc., and particularly to a foldable and detachable thermal insulation layer frame and its assembly method. Background technology:

[0002] For insulation projects on pipelines operating between 50℃ and 800℃, the currently mature construction process for valves and small equipment involves: purchasing insulation raw materials directly to the site, wrapping the valves and other equipment on-site, and securing the insulation material to the equipment using wire or steel strips; then fabricating a metal insulation outer layer to cover the insulation layer on-site. This construction process has the following disadvantages:

[0003] On-site wrapping results in varying waste from individual workers, a lack of overall design and planning, and significant material waste. Construction efficiency is difficult to control, and insulation performance is often unsatisfactory. After on-site construction, insulation products cannot be disassembled, requiring subsequent maintenance and repairs to be performed by directly removing the old insulation. Insulation materials cannot be reused, which is not environmentally friendly. Summary of the Invention:

[0004] To address the limitation of existing technologies that only allow for on-site application of insulation layers, this invention provides a foldable and detachable insulation layer frame and its assembly method. The insulation layer frame is composed of a left half-frame and a right half-frame. Both the left half-frame and the right half-frame consist of a main board located in the middle, two side plates located on the front and rear sides of the main board, and a top plate located on the top of the main board. When the insulation layer frame is not assembled, the side plates and the top plate are folded onto the inner side of the main board via a pivot connector to form a single flat surface, facilitating storage and transportation.

[0005] The assembly method is as follows:

[0006] Step 1: Open the side panel and the top panel to the predetermined position:

[0007] The side plate and the top plate are opened from the main board via the pivot connector, so that the angle between the side plate and the main board and the angle between the top plate and the main board are both 90°. At this time, the front and rear sides of the top plate are connected to the top sides of the two side plates.

[0008] Step 2: Assemble the left half frame and the right half frame respectively:

[0009] The front and rear sides of the top plate and the top sides of the two side plates are fixedly connected using locking connectors. The bottom edge of the side plate and the bottom edge of the main plate are fixedly connected using locking connectors to form the left half frame and the right half frame.

[0010] Step 3: Fill with insulation material:

[0011] Insulation material is filled into the left and right halves of the frame to form an insulation layer.

[0012] Step 4: Fix the left half frame and the right half frame together to complete the assembly.

[0013] The left and right halves of the frame are nested onto the pipe to be insulated and fixed together with fasteners to form an integral insulation layer frame. On the two side plates of the left and right halves of the frame, there are corresponding semi-circular pipe grooves. After the left and right halves of the frame are spliced ​​together, the two semi-circular pipe grooves can be spliced ​​together to form a circular pipe hole, which is used to nest the insulation layer frame on the insulation layer on both sides of the pipe to be insulated.

[0014] In step 2, when the bottom edge of the side plate is an arc-shaped bottom edge, the main board is a flat plate. The upper part of the two sides of the main board is connected to the side plate through a pivot connector. The lower part of the two sides of the main board can be bent inward to form an arc surface and is fixedly connected to the arc-shaped bottom edges of the front and rear side plates using locking connectors.

[0015] In step 2, when the bottom edge of the side panel is a straight bottom edge, the main board includes two parts: a vertical panel and a bottom panel. The bottom edge of the vertical panel is connected to the bottom panel through a pivot connector. The bottom panel can be folded inward and attached to the vertical panel. The front and rear sides of the vertical panel are connected to the side panel through pivot connectors. The front and rear sides of the bottom panel are fixedly connected to the straight bottom edge of the side panel using locking connectors.

[0016] In step 4, corresponding semi-circular tee grooves are also provided on the two top plates of the left half frame and the right half frame that are opposite each other. After the left half frame and the right half frame are spliced ​​together, the two semi-circular tee grooves that are opposite each other can be spliced ​​into a circular tee hole, which is used to nest the insulation layer frame on the upper part of the pipe to be insulated.

[0017] The top plate and the main plate are both provided with reinforcing ribs on their outer sides to reinforce them and prevent deformation.

[0018] The motherboard, the side plate, and the top plate are all elastic metal plates.

[0019] The present invention also provides a foldable and detachable insulation layer frame assembled according to the above method, wherein the insulation layer frame is composed of a left half frame and a right half frame spliced ​​together. Both the left half frame and the right half frame are composed of a main board disposed in the middle, two side plates disposed on the front and rear sides of the main board, and a top plate disposed on the top of the main board.

[0020] The side panels and the top panel can be folded onto the inner side of the main board via a pivot connector. The front and rear sides of the top panel and the top sides of the two side panels are fixedly connected by a locking connector. The bottom edge of the side panel and the bottom edge of the main board are fixedly connected by a locking connector to form the left half frame and the right half frame.

[0021] The left half-frame and the right half-frame are fixed together by fastening connectors to form an integral insulation layer frame.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The foldable and detachable insulation layer outer frame allows for optimized product structure and dimensions design, improving material utilization.

[0024] 2. It allows for quick installation of the insulation layer and ensures standardized construction quality, thereby improving the insulation effect.

[0025] 3. The outer frame is foldable, reducing transportation volume.

[0026] 4. It is a fully detachable product that can be disassembled multiple times, reducing maintenance and construction time.

[0027] 5. The foldable and detachable insulation layer outer frame can be reused repeatedly. When the inner insulation layer fails due to pollution or age, the inner insulation layer can be replaced separately, while the outer frame can continue to be reused.

[0028] 6. The soft insulation layer is combined with the outer frame, and the overall structure of the outer frame is solid, which can prevent the insulation layer from collapsing. Attached image description:

[0042] like Figures 1 to 5 As shown, this invention provides a method for assembling a foldable and detachable insulation layer frame. The insulation layer frame is characterized by being composed of a left half-frame and a right half-frame joined together. Both the left and right half-frames consist of a main board 1 located in the center, two side plates 2 located on the front and rear sides of the main board 1, and a top plate 3 located on the top of the main board 1. When the insulation layer frame is not assembled, the side plates 2 and the top plate 3 are folded onto the inner surface of the main board 1 via a pivot connector 4, forming a single flat surface for easy storage and transportation. The assembly method is as follows:

[0043] Step 1: Open the side panel 2 and the top panel 3 to the predetermined positions:

[0044] The side plate 2 and the top plate 3 are opened from the main board 1 through the pivot connector 4, so that the included angle between the side plate 2 and the main board 3 and the included angle between the top plate 3 and the main board are both 90°. At this time, the front and rear sides of the top plate 3 are connected to the top sides of the two side plates 2.

[0045] Step 2: Assemble the left half frame and the right half frame respectively:

[0046] The front and rear sides of the top plate 3 and the top sides of the two side plates 2 are fixedly connected using locking connectors 5. The bottom edge of the side plate 2 and the bottom edge of the main plate 1 are fixedly connected using locking connectors 5 to form the left half frame and the right half frame.

[0047] Step 3: Fill with insulation material:

[0048] Insulation material is filled into the left and right halves of the frame to form an insulation layer.

[0049] Step 4: Fix the left half frame and the right half frame together to complete the assembly.

[0050] The left and right halves of the frame are nested onto the pipe to be insulated and fixed together with fasteners 6 to form an integral insulation layer frame. On the two side plates 2 that are opposite to each other on the left and right halves of the frame, there are corresponding semi-circular pipe grooves 7. After the left and right halves of the frame are spliced ​​together, the two semi-circular pipe grooves 7 that are opposite to each other can be spliced ​​into circular pipe holes 8, which are used to nest the insulation layer frame on the insulation layer on both sides of the pipe to be insulated.

[0051] In step 2, when the bottom edge of the side plate 2 is an arc-shaped bottom edge, the main plate 1 is a flat plate. The upper part of the two sides of the main plate 1 is connected to the side plate 2 through the pivot connector 4. The lower part of the two sides of the main plate 1 can be bent inward to form an arc surface and is fixedly connected to the arc-shaped bottom edges of the two side plates 2 at the front and rear using locking connectors 5.

[0052] In step 2, when the bottom edge of the side panel 2 is a straight bottom edge, the main panel 1 includes two parts: a vertical panel and a bottom panel. The bottom edge of the vertical panel is connected to the bottom panel through a pivot connector 4. The bottom panel can be folded inward and attached to the vertical panel. The front and rear sides of the vertical panel are connected to the side panel 2 through the pivot connector 4. The front and rear sides of the bottom panel are fixedly connected to the straight bottom edge of the side panel 2 using a locking connector 5.

[0053] In step 4, corresponding semi-circular tee grooves 9 are also provided on the two top plates 3 that are opposite to each other on the left and right half-frames. After the left and right half-frames are spliced ​​together, the two semi-circular tee grooves 9 that are opposite to each other can be spliced ​​into a circular tee hole 10, which is used to nest the insulation layer frame on the upper part of the pipe to be insulated.

[0054] The top plate 3 and the main plate 1 are both provided with reinforcing ribs 11 on their outer sides to reinforce the top plate 3 and the main plate 1 and prevent deformation.

[0055] The main board 1, the side plate 2, and the top plate 3 are all elastic metal plates.

[0056] The present invention also provides a foldable and detachable insulation layer frame assembled according to the above method. The insulation layer frame is composed of a left half frame and a right half frame spliced ​​together. The left half frame and the right half frame are both composed of a main board 1 set in the middle, two side plates 2 set on the front and rear sides of the main board 1, and a top plate 3 set on the top of the main board 1.

[0057] The side plate 2 and the top plate 3 can be folded onto the inner side of the main plate 1 via the pivot connector 4.

[0058] The front and rear sides of the top plate 3 and the top sides of the two side plates 2 are fixedly connected by locking connectors 5. The bottom edge of the side plate 2 and the bottom edge of the main plate 1 are fixedly connected by locking connectors 5 to form the left half frame and the right half frame. The left half frame and the right half frame are fixed together by fastening connectors 6 to form an integral insulation layer frame.

[0059] On the two side plates 2 that are opposite each other on the left and right halves of the frame, there are corresponding semi-circular pipe grooves 7. After the left and right halves of the frame are spliced ​​together, the two semi-circular pipe grooves 7 that are opposite each other can be spliced ​​into circular pipe holes 8, which are used to nest the insulation layer frame on the insulation layer on both sides of the pipe to be insulated.

[0060] On the two top plates 3 that are opposite each other on the left and right half-frames, there are also corresponding semi-circular tee grooves 9. After the left and right half-frames are spliced ​​together, the two semi-circular tee grooves 9 that are opposite each other can be spliced ​​into a circular tee hole 10, which is used to nest the insulation layer frame on the upper part of the pipe to be insulated.

[0061] The foldable and detachable insulation layer outer frame of this invention can be used in common equipment such as valves, tees, and flanges. It enables foldable transportation of the outer frame, and the entire product is detachable, with the insulation layer replaceable separately.

[0062] The main board 1, side plate 2, and top plate 3 are all made of metal plates, such as galvanized iron plates, galvanized perforated iron plates, etc. Other types and materials of metal can also be used.

[0063] The reinforcing rib 11 is a metal square tube, but other types of pipe fittings can also be used.

[0064] The segmentation of the outer frame of the insulation layer can also be varied, that is, it can be a two-segment structure, or a three-segment or more-segment structure. Its shape can also be varied, it can be a frame with a round top and a round bottom, or a round tee or round cross, or a round or square shape, etc.

[0065] like Figure 6 , Figure 7 As shown, the insulation layer can be one layer, or it can be made into two or more layers. The insulation layer is further divided into the outer insulation layer 12 of the top plate, the inner insulation layer 13 of the top plate, the outer insulation layer 14 of the main plate, the inner insulation layer 15 of the main plate, the outer insulation layer 16 of the side plate, and the inner insulation layer 17 of the side plate, all of which are connected to the outer frame of the insulation layer through the insulation material fasteners 18.
