[0002] The performance and working condition of instruments directly affect the operation of process media and equipment, and thus the safe operation and economic benefits of process media and equipment.

[0003] Industrial facilities typically connect exposed water pipes to instrument lines. For ease of observation, these instrument lines are often routed from elevated locations to the ground for convenient operation. However, the medium inside these instrument lines often freezes and expands at 0°C and atmospheric pressure, causing blockages, abnormal readings, or even malfunctions in the instruments. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an energy-saving insulation device for outdoor instrument pipelines.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An energy-saving insulation device for outdoor instrument pipelines includes a pipeline body and a fitting sleeved on the pipeline body for insulation. The fitting has an inlet pipe at its head for inputting exhaust steam and an outlet at its tail for outputting condensate vapor. The fitting also includes a spiral baffle sleeved on the pipeline body for heat exchange of the exhaust steam.

[0007] The assembly structure is used to assemble the pipe fittings to provide a lateral clamping and wrapping for the pipe body;

[0008] The splicing structure is used to splice the pipe fittings and to vertically and continuously wrap the pipe body while assembling the pipe fittings.

[0009] An adjustment mechanism is used to adjust the pressure inside the pipe fitting.

[0010] Preferably, the pipe fitting includes two symmetrically arranged half-pipe fittings that wrap around the pipe body;

[0011] The semi-pipe fitting includes a semi-head connector located at the head of the pipe body, a semi-tail connector located at the tail of the pipe body, and a semi-middle connector located in the middle of the pipe body.

[0012] Preferably, the assembly structure includes:

[0013] Connecting lugs are attached to the outer walls of the two half-pipes;

[0014] A push plate is slidably mounted on one of the transverse connecting ears;

[0015] An assembly assembly is provided on another transverse connecting lug for the push plate to insert into in order to assemble two transversely arranged half-pipes.

[0016] Preferably, the assembly components include:

[0017] Multiple plug rods are vertically slidably inserted into the push plate, and the push plate is provided with plug slots for the plug rods to be inserted into. The bottom end of each plug rod is connected to a circular plate.

[0018] A plug-in post is connected to the upper end of the circular plate. Side plates are provided on both sides of the plug-in post, and a partition is provided in the middle of the side plates for the plug-in post to slide through.

[0019] A clearance member is provided above the plug-in post and is used to drive the plug-in post to slide downward so that the push plate can slide past the upper end of the plug-in post.

[0020] A third spring, sleeved on the plug post and connected between the partition and the circular plate, is used to reset the plug rod so that the plug rod can be inserted into the plug slot.

[0021] Preferably, the clearance member includes:

[0022] A push rod is slidably disposed above the plug-in post and pushes the plug-in post downward when it slides to contact the opposite surface of the plug-in post. The top of the side plate is provided with a top plate for the push rod to pass through, and the push plate is provided with a through groove for the push rod to pass through.

[0023] A limiting plate is connected to the upper end of the push rod;

[0024] A second spring is sleeved on the push rod and connected between the limiting plate and the top plate to reset the push rod to move upward.

[0025] Preferably, the splicing structure includes:

[0026] A screw is rotatably mounted on one of the vertical connecting lugs and threadedly connected to the other vertical connecting lug, for splicing two vertically arranged semi-pipe fittings;

[0027] A knob, connected to the upper end of the screw, is used to rotate the screw;

[0028] A reset element for resetting the screw to unscrew it from another vertical connecting lug.

[0029] Preferably, the reset element includes:

[0030] A steel wire rope is wound around the screw.

[0031] A slider is connected to the steel wire rope. A fixing block is provided at the upper end of the connecting lug. The fixing block is provided with a guide groove for the slider to slide. A guide rod is connected in the guide groove for the slider to pass through and guide the slider.

[0032] A first spring is sleeved on the guide rod and connected between the slider and the guide groove wall. When the first spring resets, it pulls the wire rope to disengage from the screw, thereby causing the screw to rotate in the opposite direction.

[0033] Preferably, a gear is sleeved on the screw, and a toothed plate is meshed on the gear;

[0034] The lower end of the toothed plate is connected to a guide plate that is slidably disposed on the upper end of the connecting lug. The guide plate is connected to the push plate. When the gear rotates, it drives the toothed plate to move linearly to push the push plate to move.

[0035] Preferably, the regulating mechanism includes a pressure transmitter disposed on the steam inlet pipe for measuring the pressure inside the pipe and a steam inlet regulating valve for adjusting the size of the steam inlet pipe opening according to the value of the pressure transmitter.

[0036] Preferably, the parts of the spiral baffle that contact the pipe body and the parts of the two half-pipe fittings that contact each other are provided with sealing rubber.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] 1. This invention, by setting up pipe fittings, steam inlet pipes, steam outlets and spiral baffles, allows the exhaust steam discharged from the deaerator installed near the pipeline body to enter the pipe fittings through the steam inlet pipe, exchange heat through the spiral baffles to form condensed water vapor, and then be discharged from the steam outlet. The condensed water vapor then re-enters the deaerator for recycling, thus achieving both heat preservation of the pipeline body and recycling of exhaust steam.

[0039] 2. This invention, through its assembly and splicing structures, achieves connection between two vertical half-pipe fittings and two horizontal half-pipe fittings simultaneously. Furthermore, the insertion of the plug rod into the plug slot limits both the push plate and the screw's rotation, ensuring the stability of the connection between the two vertical and two horizontal half-pipe fittings. Additionally, the cooperation of the reset component and the downward-pushing limiting plate causes the screw to rotate in the opposite direction, separating the push plate and the plug rod, thus achieving separation between the two vertical and two horizontal half-pipe fittings simultaneously. This operation is time-saving and labor-saving, facilitating the installation and removal of pipe fittings on the pipeline body.

[0040] 3. This invention uses an adjustment mechanism, a pressure transmitter to measure the pressure inside the pipe fitting, and a steam inlet regulating valve to adjust the size of the steam inlet pipe opening based on the pressure transmitter value, thereby preventing excessive pressure inside the pipe fitting.

[0041] 4. By incorporating sealing rubber, this invention improves heat exchange within the pipe fittings and prevents temperature loss. Attached Figure Description

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Please see Figure 1-11 An energy-saving insulation device for outdoor instrument pipelines includes a pipeline body 1 and a fitting sleeved on the pipeline body 1 for insulation. The fitting has an inlet pipe 21 for inputting exhaust steam at its head and an outlet port 9 for outputting condensate vapor at its tail. The fitting also includes a spiral baffle 5 sleeved on the pipeline body 1 for heat exchange of exhaust steam.

[0062] The assembly structure is used to assemble pipe fittings to provide a lateral clamping and wrapping for the pipe body 1;

[0063] The splicing structure is used to splice pipe fittings, and to vertically and continuously wrap the pipe body 1 while assembling the pipe fittings.

[0064] The regulating mechanism is used to regulate the pressure inside the pipe fitting.

[0065] This design allows the pipe fittings to be fitted onto the pipe body 1. The pipe fittings are assembled horizontally through the assembly structure and vertically through the splicing structure, achieving the connection between the pipe fittings and ensuring that the pipe fittings are stably fitted onto the pipe body 1. The exhaust steam discharged from the deaerator installed near the pipe body 1 enters the pipe fitting through the steam inlet pipe 21, undergoes heat exchange through the spiral baffle 5 to form condensed water vapor, and then exits from the steam outlet 9. The condensed water vapor re-enters the deaerator for recycling, thus achieving both heat preservation of the pipe body 1 and recycling of exhaust steam.

[0066] In one embodiment, the fitting includes two symmetrically arranged half-pipe fittings that wrap around the pipe body 1;

[0067] The semi-pipe fittings include a semi-head connector 2 located at the head of the pipe body 1, a semi-tail connector 4 located at the tail of the pipe body 1, and a semi-middle connector 3 located in the middle of the pipe body 1.

[0068] In one embodiment, the assembly structure includes:

[0069] Connecting lug 6 is attached to the outer wall of the two half-pipe fittings;

[0070] Push plate 712 is slidably mounted on one of the transverse connecting ears 6;

[0071] The assembly component is located on another transverse connecting lug 6, through which the push plate 712 is inserted to assemble two transversely arranged half-pipes.

[0072] With this design, the connecting lug 6 located on the head pipe 2 and near the steam inlet pipe 21 is equipped with bolts 8 and is connected and installed by bolts 8. The connecting lug 6 located on the tail pipe 4 and near the steam outlet 9 is equipped with bolts 8 and is connected and installed by bolts 8. The remaining connecting lugs 6 are connected and installed by assembly and splicing structures, which helps to save time and effort.

[0073] In one embodiment, the assembly component includes:

[0074] Multiple plug rods 720 are vertically slidably plugged into a push plate 712. The push plate 712 is provided with plug slots for the plug rods 720 to be plugged into. The bottom end of the plug rod 720 is connected to a circular plate 719.

[0075] The plug-in post 718 is connected to the upper end of the circular plate 719. Side plates 713 are provided on both sides of the plug-in post 718, and a partition 722 is provided in the middle of the side plate 713 for the plug-in post 718 to slide through.

[0076] A clearance member is provided above the plug-in post 718 and is used to drive the plug-in post 718 to slide downward so that the push plate 712 can slide past the upper end of the plug-in post 718.

[0077] The third spring 721 is sleeved on the plug post 718 and connected between the partition plate 722 and the circular plate 719. It is used to reset the plug rod 720 so that the plug rod 720 can be inserted into the plug groove.

[0078] With this design, the side plate 713 is fixedly installed on the connecting ear 6; the partition plate 722 is fixedly connected to the side plate 713; the plug rod 720 and the plug post 718 both pass through the partition plate 722 and slide on the partition plate 722, and the bottom ends of the plug rod 720 and the plug post 718 are fixedly connected to the circular plate 719; one end of the third spring 721 is fixedly connected to the partition plate 722, and the other end is fixedly connected to the circular plate 719.

[0079] In one embodiment, the clearance member includes:

[0080] Push rod 715 is slidably disposed above plug post 718 and pushes plug post 718 downward when it slides to contact the opposite surface of plug post 718. The top of side plate 713 is provided with top plate 714 for push rod 715 to pass through, and push plate 712 is provided with through groove 723 for push rod 715 to pass through.

[0081] Limit plate 717 is connected to the upper end of push rod 715;

[0082] The second spring 716 is sleeved on the push rod 715 and connected between the limiting plate 717 and the top plate 714 to reset the push rod 715 to move upward.

[0083] With this design, the side plate 713 is fixedly connected to the top plate 714; the push rod 715 passes through the top plate 714 and slides on the top plate 714; one end of the second spring 716 is fixedly connected to the limiting plate 717, and the other end is fixedly connected to the top plate 714; the push rod 715 and the limiting plate 717 are fixedly connected.

[0084] This design involves pressing the limiting plate 717, causing the push rod 715 to move downwards, compressing the second spring 716, and positioning the push rod 715 and the insertion post 718 directly opposite each other. The push rod 715 pushes the insertion post 718 downwards, causing the insertion rod 720 to move downwards, and stretching the third spring 721. Next, the push plate 712 slides through the side plate 713 to above the insertion post 718. The downward movement of the insertion rod 720 does not interfere with the lateral movement of the push plate 712. The coordinated use of the through slot 723, the push rod 715, and the insertion post 718 also does not interfere with the lateral movement of the push plate 712. After releasing the limiting plate 717, the push rod 715 moves upwards under the action of the second spring 716, and the insertion post 718 moves upwards without the pressure of the push rod 715, causing the insertion rod 720 to insert into the insertion slot, limiting the push plate 712 and achieving the connection between the two lateral half-pipes.

[0085] In one embodiment, the splicing structure includes:

[0086] The screw 702 is rotatably mounted on one of the vertical connecting lugs 6 and threadedly connected to the other vertical connecting lug 6, and is used to splice two vertically arranged half-pipes;

[0087] Knob 701 is connected to the upper end of screw 702 and is used to rotate screw 702;

[0088] A reset element is used to reset the screw 702 so that it can be unscrewed from another vertical connecting lug 6.

[0089] With this design, the screw 702 is fixedly connected to the knob 701.

[0090] In one embodiment, the reset element includes:

[0091] Wire rope 704 is wound around screw 702;

[0092] The slider 708 is connected to the wire rope 704. The upper end of the connecting ear 6 is provided with a fixing block 705. The fixing block 705 is provided with a guide groove 706 for the slider 708 to slide. A guide rod 707 is connected in the guide groove 706 for the slider 708 to pass through and guide the slider 708.

[0093] The first spring 709 is sleeved on the guide rod 707 and connected between the slider 708 and the groove wall of the guide groove 706. When the first spring 709 is reset, it pulls the wire rope 704 to disengage from the screw 702, thereby causing the screw 702 to rotate in the opposite direction.

[0094] With this design, the fixing block 705 is fixedly connected to the upper end of the connecting ear 6; the guide rod 707 is fixedly connected to the guide groove 706; one end of the wire rope 704 is fixedly connected to the screw 702, and the other end is fixedly connected to the slider 708; one end of the first spring 709 is fixedly connected to the groove wall of the guide groove 706, and the other end is fixedly connected to the slider 708.

[0095] With this design, rotating the knob 701 in the forward direction drives the screw 702 to rotate. The screw 702 rotates on one of the vertical connecting lugs 6 and screws into the other vertical connecting lug 6, thus connecting the two vertical connecting lugs 6 to achieve the connection between the two vertical half-pipes. The wire rope 704 is wound around the screw 702. At this time, the wire rope 704 pulls the slider 708 to slide in the guide groove 706, and the first spring 709 is compressed. After releasing the knob 701, the first spring 709 returns to its original position, causing the slider 708 to slide away from the screw 702, thereby causing the wire rope 704 to disengage from the screw 702. This, in turn, causes the screw 702 to rotate in the reverse direction, rotating on one of the vertical connecting lugs 6 and screwing out of the other vertical connecting lug 6, thus achieving the disassembly of the two vertical half-pipes.

[0096] In one embodiment, a gear 703 is sleeved on the screw 702, and a toothed plate 710 is meshed on the gear 703;

[0097] The lower end of the toothed plate 710 is connected to a guide plate 711 that is slidably disposed on the upper end of the connecting ear 6. The guide plate 711 is connected to the push plate 712. When the gear 703 rotates, it drives the toothed plate 710 to move linearly to push the push plate 712 to move.

[0098] With this design, the upper end of the connecting ear 6 is provided with a limiting groove for the linear movement of the guide plate 711; the upper end of the guide plate 711 is fixedly connected to the toothed plate 710, and the side end is fixedly connected to the push plate 712.

[0099] This design allows the screw 702 to rotate in the forward direction, driving the gear 703 to rotate. This, in turn, moves the toothed plate 710 towards the insertion rod 720, causing the push plate 712 to move into the side plate 713 and above the insertion rod 720. This achieves connection between the two vertical half-pipe fittings and the two horizontal half-pipe fittings simultaneously. Furthermore, the insertion of the insertion rod 720 into the insertion slot limits the push plate 712 and also limits the rotation of the screw 702, ensuring the stability of the connection between the two vertical and two horizontal half-pipe fittings. Additionally, with the cooperation of the reset component and the downward-pushing limiting plate 717, the screw 702 rotates in the reverse direction, causing the push plate 712 and the insertion rod 720 to separate, achieving separation between the two vertical and two horizontal half-pipe fittings simultaneously. This operation is time-saving and labor-saving, facilitating the installation and removal of pipe fittings on the pipe body 1.

[0100] In one embodiment, the regulating mechanism includes a pressure transmitter 22 disposed on the steam inlet pipe 21 for measuring the pressure inside the pipe and a steam inlet regulating valve 23 for adjusting the size of the opening of the steam inlet pipe 21 according to the value of the pressure transmitter 22.

[0101] With this design, the pressure transmitter 22 and the steam inlet regulating valve 23 are electrically connected. The pressure transmitter 22 measures the pressure inside the pipe, and the steam inlet regulating valve 23 adjusts the size of the steam inlet pipe 21 according to the value of the pressure transmitter 22 to prevent the pressure inside the pipe from being too high.

[0102] Sealing rubber is provided at the contact points between the spiral baffle 5 and the pipe body 1, as well as at the contact points between the two half-pipe fittings.

[0103] This design ensures that the sealing rubber seals the connection between the two pipe halves, and similarly, it also seals the connection between the spiral baffle 5 and the pipe body 1, resulting in better heat exchange within the pipe and preventing heat loss.

[0104] Working principle: During use, the pipe fittings are fitted onto the pipe body 1. The pipe fittings are assembled horizontally through the assembly structure and vertically through the splicing structure to achieve the connection between the pipe fittings and to stably fit onto the pipe body 1. The exhaust steam discharged from the deaerator installed near the pipe body 1 enters the pipe fitting through the steam inlet pipe 21, passes through the spiral baffle 5 for heat exchange to form condensed water vapor, and then exits from the steam outlet 9. The condensed water vapor re-enters the deaerator for recycling, thus achieving heat preservation of the pipe body 1 while also recycling the exhaust steam.

[0105] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0106] Furthermore, if the embodiments of this invention involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention. It is obvious to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that this invention can be implemented in other specific forms without departing from the spirit or basic characteristics of this invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within the invention.
