Description

Technical Field

[0001] This invention relates to the field of valve heater technology, and more specifically to a flexible electric heater. Background Technology

[0002] Valve heaters are valve devices that integrate heating functions. They are mainly used for temperature control of fluids in pipelines and are commonly found in industrial systems that require maintaining or regulating fluid temperature. The core function of valve heaters is to heat or keep the fluid flowing through the valve at a specific temperature using built-in or external heating elements, preventing the fluid from cooling, increasing viscosity, or solidifying, thus ensuring stable system operation.

[0003] A flexible, stretchable electric heating device based on paper-aluminum-plastic packaging material is disclosed in authorization announcement number CN113079598A. The electric heater comprises four parts: a conductor, a conductor-supporting structure, electrodes, and a power supply. The conductor, conductor-supporting structure, and electrodes constitute the main body of the flexible electric heater, all made of Tetra Pak packaging. The aluminum foil layer of the Tetra Pak packaging serves as the conductor, utilizing its Joule heating effect. In use, heating is initiated by connecting a DC or AC power supply to the two ends of the electrodes. The Tetra Pak packaging can be cut into stretchable structures using paper-cutting techniques to achieve a wearable electric heater. This invention enables the simple processing of waste Tetra Pak packaging into an environmentally friendly flexible electric heater, increasing the added value of waste Tetra Pak packaging. This flexible electric heater can be applied in fields such as thermal information display and wearable thermal diagnostics.

[0004] The existing technology has the following shortcomings: During the installation and use of existing valve heaters, the side of the valve is usually heated by a common patch silicone heater, which cannot fully heat the bottom of the valve. In addition, after a long period of use, the fit may deteriorate due to aging and other reasons, affecting the heating effect. Furthermore, the heating temperature of conventional patch heaters is generally less than 100℃, and it is difficult to apply higher temperatures. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible electric heater. By placing the heater body at the bottom of the valve, the heating effect of the heater can be improved. The first fixing plate, two second fixing plates, and two sealing plates can seal the connection between the heater body and the valve, thereby preventing the heater body from shifting and solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flexible electric heater, comprising a heater body, and further comprising:

[0007] The fixing mechanism located on the outside of the heater body is used to seal the connection between the heater body and the valve and to fix the heater body.

[0008] The fixing mechanism includes a first fixing plate and two second fixing plates. The first fixing plate is disposed on one side of the heater body, and a first fixing bolt is threaded between the first fixing plate and the heater body. The two second fixing plates are respectively disposed at both ends of the other side of the heater body, and a second fixing bolt is threaded between the second fixing plate and the heater body. Both ends of the first fixing plate are provided with sealing plates that are connected to the second fixing plates at the same end. Rotating plates are rotatably installed on the outer walls of both ends of the first fixing plate and one end of the two second fixing plates. Two fastening bolts are threaded between the two rotating plates at the same end and the sealing plates at the same end.

[0009] Preferably, the heater body includes a support plate, a heating wire is laid on the top of the support plate, a cover plate is laid on the top of the heating wire, and connecting wires are fixedly installed at both ends of the heating wire, with connecting plugs fixedly installed at the ends of the two connecting wires away from the heating wire.

[0010] Preferably, a first fixing plate is fixedly installed on one side of the support plate where it connects with the cover plate, and a plurality of first fixing holes are equally spaced on the inner side of the first fixing plate. Two second fixing plates are fixedly installed on the other side of the support plate where it connects with the cover plate, and a plurality of second fixing holes are equally spaced on the inner side of the two second fixing plates.

[0011] Preferably, the first fixing plate has a first insertion slot, which is movably sleeved on the outside of the first fixing piece. A plurality of first fixing bolts are threaded into the top of the first fixing plate and pass through adjacent first fixing holes and are threadedly connected to the bottom of the first fixing plate.

[0012] Preferably, both second fixing plates are provided with second insertion slots, and the two second insertion slots are respectively movably sleeved on the outside of the two second fixing plates. Multiple second fixing bolts at the same end are threaded into the top of the adjacent second fixing plates and pass through the adjacent second fixing holes and are threadedly connected to the bottom of the second fixing plates.

[0013] Preferably, the first fixing plate has storage grooves at both ends and one end of the two second fixing plates. The sealing plate has sliders fixedly installed on both sides. The two sliders at the same end are respectively movably inserted into the adjacent storage grooves. The sealing plate has two mounting holes on both sides.

[0014] Preferably, each of the two rotating plates at the same end has a movable groove on its opposite side, the movable groove is connected to the adjacent storage groove, the inner wall of the rotating plate has two connecting holes, the inner wall of the connecting holes is threaded to the adjacent fastening bolt, and the end of the fastening bolt away from the connecting hole is threaded to the adjacent mounting hole.

[0015] Preferably, the height of the first fixing plate and the height of the second fixing plate are the same, the height of the first fixing plate is the same as the height of the sealing plate, and the height of the sealing plate is the same as the height of the rotating plate.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] 1. By placing the heater body between the valve and the base, the heating range of the heater can be increased, thereby improving the heating effect. This avoids problems such as poor fit after long-term use of ordinary heaters. At the same time, the first fixing plate and two second fixing plates can fix the positions on both sides of the heater body, so that the first fixing plate and the second fixing plate can seal both sides of the connection between the valve and the base. Pushing the sealing plate allows it to move along the movable groove to the adjacent storage groove via the slider. Then, the rotation of the rotating plate can fix the moved sealing plate. The sealing plate and the rotating plate can be fixed with fastening bolts. The two sealing plates can seal both ends of the connection between the valve and the base, thereby limiting the position of the heater body and preventing it from shifting. This allows it to heat stably and ensures the heating effect of the heater body.

[0018] 2. The connection between the support plate and the cover plate can be sealed and fixed by the first fixing plate and the two second fixing plates, so that the heating wire can remain stable between the support plate and the cover plate. At the same time, it can prevent the heating wire from loosening during long-term operation of the heater body. The first fixing plate is inserted into the first insertion slot, the second fixing plate is inserted into the second insertion slot, the first fixing bolt is threaded into the first fixing plate and the first fixing plate, and the second fixing bolt is threaded into the second fixing plate and the second fixing plate. This allows the first fixing plate and the second fixing plate to fix the first fixing plate and the second fixing plate, so that the fixing mechanism can stably reinforce both sides of the heater body.

[0029] This invention provides, for example Figure 1 The flexible electric heater shown includes a heater body 1, and further includes:

[0030] The fixing mechanism 2, located on the outside of the heater body 1, is used to seal the connection between the heater body 1 and the valve and to fix the heater body 1.

[0031] In order to keep the heater body 1 stable during the heating process, such as Figure 1-6As shown, the fixing mechanism 2 includes a first fixing plate 201 and two second fixing plates 204. The first fixing plate 201 is disposed on one side of the heater body 1, and a first fixing bolt 203 is threadedly inserted between the first fixing plate 201 and the heater body 1. The two second fixing plates 204 are respectively disposed at both ends of the other side of the heater body 1, and a second fixing bolt 206 is threadedly inserted between the second fixing plates 204 and the heater body 1. Both ends of the first fixing plate 201 are provided with sealing plates 211 that connect to the second fixing plates 204 at the same end. Rotating plates 208 are rotatably mounted on the outer walls of both ends of the first fixing plate 201 and one end of the two second fixing plates 204. The two rotating plates 208 at the same end and the sealing plates 211 at the same end are connected to each other. Two fastening bolts 214 are threadedly inserted between the heater body 1 and the first fixing bolt 203 and the second fixing bolt 206. The first fixing plate 201 and the two second fixing plates 204 can be connected and fixed to the heater body 1, so that the first fixing plate 201 and the two second fixing plates 204 can reinforce both sides of the heater body 1 and seal both sides of the connection between the valve and the base. At the same time, the sealing plate 211 can be limited by the rotating plate 208. The fastening bolts 214 pass through the rotating plate 208 and are threadedly connected to the sealing plate 211, which can fix the rotating plate 208 and the sealing plate 211, so that the two sealing plates 211 can seal both ends of the connection between the valve and the base.

[0032] In order to ensure that the heater body 1 can heat stably, such as Figure 1-2 and Figure 4 , Figure 6 As shown, the heater body 1 includes a support plate 101, a heating wire 102 is laid on the top of the support plate 101, a cover plate 103 is laid on the top of the heating wire 102, and connecting wires 104 are fixedly installed at both ends of the heating wire 102. Connecting plugs 105 are fixedly installed at the ends of the two connecting wires 104 away from the heating wire 102. The heating wire 102 can be installed and fixed through the support plate 101 and the cover plate 103. The connecting plugs 105 can be connected and fixed to the heating wire 102 through the connecting wires 104. Then, the heating wire 102 can heat the valve through the connection of the connecting plugs 105 to the power supply.

[0033] In order to ensure that the fixing mechanism 2 can stably reinforce both sides of the heater body 1, such as Figure 2-5As shown, a first fixing plate 106 is fixedly installed on one side of the support plate 101 where it connects with the cover plate 103. Multiple first fixing holes 107 are evenly spaced on the inner side of the first fixing plate 106. Two second fixing plates 108 are fixedly installed on the other side of the support plate 101 where it connects with the cover plate 103. Multiple second fixing holes 109 are evenly spaced on the inner side of each of the two second fixing plates 108. A first fixing plate 201 has a first insertion groove 202, which is movably fitted onto the outer side of the first fixing plate 106. Multiple first fixing bolts 203 are threaded into the top of the first fixing plate 201, pass through adjacent first fixing holes 107, and are threadedly connected to the bottom of the first fixing plate 201. Both second fixing plates 204 have second insertion grooves 205. The insertion slots 205 are respectively movably sleeved on the outside of the two second fixing plates 108. Multiple second fixing bolts 206 at the same end are threaded into the top of the adjacent second fixing plates 204 and pass through the adjacent second fixing holes 109 and are threadedly connected to the bottom of the second fixing plates 204. The first fixing plate 106 and the two second fixing plates 108 can reinforce the connection position between the support plate 101 and the cover plate 103. The first fixing plate 106 is inserted into the first insertion slot 202 and fixed by the first fixing bolt 203. The second fixing plate 108 is inserted into the second insertion slot 205 and fixed by the second fixing bolt 206, so that the first fixing plate 201 and the second fixing plate 204 can further reinforce the first fixing plate 106 and the second fixing plate 108.

[0034] In order to ensure that the sealing plate 211 stably seals both ends of the connection between the valve and the base, such as Figure 2-3 and Figure 5-6As shown, both ends of the first fixed plate 201 and one end of the two second fixed plates 204 are provided with storage grooves 207. Slider blocks 212 are fixedly installed on both sides of the sealing plate 211. Two sliders 212 at the same end are movably inserted into adjacent storage grooves 207. Two mounting holes 213 are provided on both sides of the sealing plate 211. Movable grooves 209 are provided on opposite sides of the two rotating plates 208 at the same end. The movable grooves 209 communicate with adjacent storage grooves 207. Two connecting holes 210 are provided on the inner wall of the rotating plate 208. The inner wall of the connecting hole 210 is threadedly connected to adjacent fastening bolts 214. The end of the fastening bolt 214 away from the connecting hole 210 is threadedly connected to the adjacent mounting hole 213. The height of the first fixed plate 201 and the second fixed plate 204 are... The height dimensions of the first fixed plate 201 and the sealing plate 211 are the same. The height dimensions of the sealing plate 211 and the rotating plate 208 are the same. The sealing plate 211 is moved to the receiving groove 207 at the same end by two sliders 212 along the inner wall of the adjacent movable groove 209. Then, the rotating plate 208 is rotated from the horizontal position to the vertical position, which can limit the moved sealing plate 211. Then, the fastening bolt 214 is threaded into the inner wall of the connecting hole 210 and threadedly connected to the adjacent mounting hole 213. The adjusted rotating plate 208 and the sealing plate 211 can be fixed, so that the two sealing plates 211 can stably seal the two ends of the connection position between the valve and the base.

[0035] The specific implementation method is as follows: When installing and using the heater body 1, the support plate 101 and the cover plate 103 are manufactured according to the shape of the valve and the base, so that the heating wire 102 can be installed between the support plate 101 and the cover plate 103. Then, a first fixing piece 106 and a second fixing piece 108 are respectively manufactured on both sides of the joint position of the support plate 101 and the cover plate 103 to reinforce the connection position between the support plate 101 and the cover plate 103. Then, the first fixing piece 106 is inserted into the first insertion groove 202 on the inner side of the first fixing plate 201, and then the first fixing bolt 203 is used. Fix it, and insert the two second fixing pieces 108 into the second insertion slots 205 on the inner side of the two second fixing plates 204 respectively. Then fix it with the second fixing bolts 206 so that the first fixing plate 201 and the two second fixing plates 204 can reinforce the first fixing piece 106 and the second fixing piece 108. Then install the heater body 1 into the gap between the valve and the base, so that the first fixing plate 201 and the two second fixing plates 204 can be respectively fitted on the outside of the connection position between the valve and the base so that they can seal both sides of the connection position between the valve and the base.

[0036] Then, by moving the sealing plate 211, it moves along the inner wall of the adjacent movable groove 209 to the adjacent receiving groove 207 via the slider 212, so that the two sealing plates 211 can seal both ends of the connection between the valve and the base. At the same time, the position of the rotating plate 208 is adjusted so that it rotates from a horizontal position to a vertical position, so that the two rotating plates 208 at the same end are on the outer walls of the adjacent sealing plates 211, so that the connecting hole 210 can be aligned with the adjacent mounting hole 213. Then, the fastening bolt 214 is threaded into the connecting hole 210 and threadedly connected to the inner wall of the adjacent mounting hole 213, which can seal the rotating plate 208 and the sealing plate 211. The valve is fixed in place, and the connection between the valve and the base is sealed by the fixing mechanism 2. Then, the two connecting plugs 105 are connected to the power supply, and the connecting wire 104 can supply energy to the heating wire 102, so that it can stably heat the valve. By placing the heater body 1 between the valve and the base, the heating range can be increased. At the same time, the setting of the fixing mechanism 2 can ensure the stability of the heater body 1, and can prevent it from shifting during long-term operation, thus ensuring the heating effect of the heater body 1. This embodiment specifically solves the problem of poor heating effect of valve heaters in the prior art.

[0037] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
