Description

Technical Field

[0001] The utility model relates to the technical field of metal welded bellows, in particular to a high-pressure-resistant metal welded bellows. Background Art

[0002] A metal welded bellows is a tubular component formed by stamping a metal thin plate into a waveform and then welding it, having good flexibility and bendability. It is widely used in fields such as instruments, aerospace, and the electronics industry, as sensitive components, sealing components, isolating media, pipeline connections, and temperature compensators, etc.

[0003] Metal welded bellows are very widely used in daily life. Metal welded bellows have good flexibility and bendability. When metal welded bellows are in use, they often get damaged due to extrusion, thus causing certain losses to users. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a high-pressure-resistant metal welded bellows.

[0005] The utility model is implemented by the following technical solutions: A high-pressure-resistant metal welded bellows includes a compression-resistant mechanism, a fixing mechanism, and a main body mechanism. The compression-resistant mechanism is located inside the main body mechanism, and the fixing mechanism is located on the outer wall of the compression-resistant mechanism.

[0006] The compression-resistant mechanism includes a bellows main body. A wave valley is provided on the outer wall of the bellows main body, and a clamping ring is fixedly connected to the outer wall of the wave valley.

[0007] Through the above technical solutions, a wave valley is provided on the outer wall of the bellows main body. By setting the wave valley on the outer wall of the bellows main body, when the bellows main body is twisted and folded, the overall shape and bending angle of the bellows main body can be changed by stretching and squeezing the wave valley, thereby increasing the flexibility and plasticity of the overall device. By setting a large number of wave valleys, the density of the wave peaks is increased, thus increasing the force-bearing area of the overall device. A clamping ring is fixedly connected to the wave valley. By fixedly connecting the clamping ring to the inner wall of the wave valley, the supporting area for the overall device to bear force is increased. When the outer wall of the device is deformed due to being squeezed by a heavy object, the clamping ring is fixedly connected to the bellows main body through the outer wall, thereby increasing the stability of the overall mechanical device.

[0008] As a further improvement of the above solution, a support rod is fixedly connected to the outer wall of the clamping ring. A movable baffle is slidably connected to the outer wall of the support rod, and a compression spring is fixedly connected to the outer wall of the movable baffle.

[0009] Through the above technical solution, the snap ring is fixedly connected to the support rod, and the support rod is slidably connected to the movable baffle. By fixedly connecting the support rod to the outer wall of the snap ring and slidably connecting the support rod to the movable baffle, the overall support area is increased. By fixedly connecting a compression spring to the outer wall of the movable baffle, when the corrugated pipe body is folded and twisted, the compression spring contracts and stretches following the outer wall shape of the corrugated pipe body, so as to increase the folding angle of the device as much as possible and prevent the movable baffle from affecting the folding range of the corrugated pipe body. When the mechanical equipment is subjected to a lateral squeezing force, the movable baffle squeezes the compression spring inward, thereby slowing down the pressure on the equipment and increasing the compressive resistance of the equipment.

[0010] As a further improvement of the above solution, a rubber extrusion block is fixedly connected to the outer wall of the movable baffle.

[0011] Through the above technical solution, the movable baffle is fixedly connected to the rubber extrusion block. By arranging the rubber extrusion block to be fixedly connected to the outer wall of the corrugated pipe body, and by arranging the movable baffle and the rubber extrusion block to be symmetrically distributed and both closely attached to the outer wall of the corrugated pipe body, it is prevented that the wave crest collapses due to extrusion, thereby increasing the overall support and stability of the equipment.

[0012] As a further improvement of the above solution, the fixing mechanism includes a connecting housing. A threaded port is arranged inside the connecting housing. The outer wall of the connecting housing is slidably connected to the corrugated pipe body, and a fixing flange is fixedly connected to the outer wall of the corrugated pipe body.

[0013] Through the above technical solution, the two ends of the corrugated pipe body are respectively fixedly connected to the connecting housing and the fixing flange. By arranging the connecting housing and the fixing flange to connect the equipment to the outer wall water pipe, and by arranging a threaded port on the inner wall of the connecting housing, the connecting housing is conveniently connected to the outer wall of the water pipe through the threaded port, thereby increasing the convenience of the overall equipment.

[0014] As a further improvement of the above solution, a sealing ring is fixedly connected to the inner wall of the connecting housing.

[0015] Through the above technical solution, the connecting housing is fixedly connected to the sealing ring. When the water pipe is connected, the sealing ring closely fits the outer walls of the corrugated pipe body and the connecting housing, thereby increasing the sealing performance of the overall mechanical equipment.

[0016] As a further improvement of the above solution, the main body mechanism includes a first elastic net layer. A decompression spring is fixedly connected to the lower surface of the first elastic net layer, and a second elastic net layer is fixedly connected to the inner wall of the decompression spring.

[0017] Through the above technical solution, a decompression spring is arranged on the lower surface of the first elastic net layer. The second elastic net layer is fixedly connected to the inner wall of the decompression spring. By arranging two elastic net layers, the wear resistance of the outer wall of the mechanical equipment is improved. By arranging a decompression spring between the first elastic net layer and the second elastic net layer, when the outside of the mechanical equipment is squeezed, the decompression spring is squeezed, thereby increasing the pressure resistance of the overall equipment.

[0018] As a further improvement of the above solution, a welding joint is fixedly connected to the outer wall of the first elastic net layer.

[0019] Through the above technical solution, the first elastic net layer is fixedly connected to the welding joint, thereby increasing the stability of the overall mechanical equipment.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] In the present utility model, by arranging troughs on the outer wall of the corrugated pipe body, when the corrugated pipe body is twisted and folded, the overall shape and bending angle of the corrugated pipe body can be changed by stretching and squeezing the troughs, thereby increasing the flexibility and plasticity of the overall equipment. The troughs are fixedly connected to clamping rings. By fixedly connecting clamping rings to the inner walls of the troughs, the supporting area of the overall equipment under stress is increased. The clamping rings are fixedly connected to the corrugated pipe body through the outer wall, thereby increasing the stability of the overall mechanical equipment. By fixedly connecting a compression spring to the outer wall of the movable baffle, when the mechanical equipment is subjected to a lateral squeezing force, the movable baffle squeezes the compression spring inward, thereby reducing the pressure on the equipment and increasing the pressure resistance of the equipment. By arranging rubber extrusion blocks fixedly connected to the outer wall of the corrugated pipe body, and by arranging the movable baffle and the rubber extrusion blocks symmetrically and both closely attached to the outer wall of the corrugated pipe body, the prevention of the collapse of the wave crest due to extrusion is achieved, thereby increasing the overall support and stability of the equipment.

[0022] The inner wall of the connection housing of the present utility model is provided with a threaded port, which can quickly and stably achieve threaded connection with the outer wall of the water pipe, greatly improving the convenience of equipment installation and disassembly. A sealing ring is arranged at the contact part between the connection housing and the corrugated pipe body. By closely fitting the outer walls of both, the leakage of liquid or gas is effectively prevented, ensuring the sealing performance of the overall mechanical equipment during the working process.

[0030] Next, in combination with the attached drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0031] Embodiment:

[0032] Please combine Figures 1-5 , A high-pressure-resistant metal welded bellows of this embodiment includes a compression resistance mechanism 1, a fixing mechanism 2 and a main body mechanism 3. The compression resistance mechanism 1 is located inside the main body mechanism 3, and the fixing mechanism 2 is located on the outer wall of the compression resistance mechanism 1;

[0033] The compression resistance mechanism 1 includes a bellows main body 101. Wave troughs 102 are arranged on the outer wall of the bellows main body 101, and a snap ring 103 is fixedly connected to the outer wall of the wave trough 102.

[0034] A support rod 105 is fixedly connected to the outer wall of the snap ring 103. A moving baffle 106 is slidably connected to the outer wall of the support rod 105, and a compression spring 104 is fixedly connected to the outer wall of the moving baffle 106.

[0035] A rubber extrusion block 107 is fixedly connected to the outer wall of the moving baffle 106.

[0036] The fixing mechanism 2 includes a connection housing 201. A threaded port 203 is arranged inside the connection housing 201. The bellows main body 101 is slidably connected to the outer wall of the connection housing 201, and a fixed flange 202 is fixedly connected to the outer wall of the bellows main body 101.

[0037] A sealing ring 204 is fixedly connected to the inner wall of the connection housing 201.

[0038] The main body mechanism 3 includes a first elastic mesh layer 301. A decompression spring 302 is fixedly connected to the lower surface of the first elastic mesh layer 301. A second elastic mesh layer 303 is fixedly connected to the inner wall of the decompression spring 302.

[0039] A welding joint 304 is fixedly connected to the outer wall of the first elastic mesh layer 301.

[0040] The implementation principle of a high-pressure-resistant metal welded bellows in the embodiment of the present application is as follows: The outer wall of the bellows main body 101 is provided with wave valleys 102, so that when the bellows main body 101 is twisted and folded, it can change its shape and bending angle by stretching and squeezing the wave valleys 102, increasing the flexibility and plasticity of the bellows 102. The clamping rings 103 fixedly connected to the inner walls of the wave valleys 102 increase the support area when the bellows 102 is stressed, improving the stability of the overall structure. The clamping rings 103 are fixedly connected to the brackets 105. The brackets 105 are slidably connected to the moving baffles 106. Compression springs 104 are fixedly connected to the outer walls of the moving baffles 106. When the bellows main body 101 is subjected to a lateral extrusion force, through the inward extrusion of the moving baffles 106, the pressure received by the equipment is reduced, thereby enhancing the compressive resistance of the bellows main body 101. Through the symmetrically distributed moving baffles 106 and rubber extrusion blocks 107 on the outer wall of the bellows main body 101, it can effectively prevent the wave crests from collapsing due to extrusion, enhancing the overall support and stability of the equipment. Threaded ports 203 are provided on the inner wall of the connecting housing 201. By using the threaded ports 203 to threadedly connect with the threaded parts on the outer wall of the water pipe, the rapid and convenient connection between the equipment and the water pipe is realized, greatly improving the installation and disassembly efficiency. The sealing rings 203 are fixedly connected to the connecting housing 201. When the equipment is connected to the water pipe, the sealing rings 203 can closely fit the outer walls of the bellows main body 101 and the connecting housing 201 to form a sealing layer, thus ensuring the sealing performance of the overall mechanical equipment during the working process.

[0041] The above implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the protection scope of the present utility model.
