Description

Technical Field

[0001] The utility model belongs to the technical field of corrosion prevention of stainless steel joints, in particular to an anti-corrosion device for stainless steel joints. Background Art

[0002] Stainless steel joints are a type of connector made of corrosion-resistant alloy steel. They are mainly used in pipeline systems, mechanical equipment and other applications that require corrosion-resistant connections to achieve safe transmission of fluids or gases or stable connections between mechanical parts. Stainless steel joints have excellent corrosion resistance, high strength, good processability and long service life. They have been widely used in chemical, petroleum, pharmaceutical, food processing and other industries. They can not only withstand high pressure and high temperature environments, but also resist the erosion of various chemical media to ensure the reliability and safety of the system. Through different forms, such as threaded, welded, ferrule, etc., stainless steel joints can meet diverse connection needs and become one of the indispensable components in modern industry.

[0003] Due to the lack of corrosion-resistant devices for existing stainless steel joints, the problem with the above technology is that although existing stainless steel joints are widely used in many industrial fields due to the corrosion resistance of the material itself, they still face potential corrosion risks over time due to the lack of special corrosion-resistant devices. Especially in some extreme environments, such as high humidity, salt spray or the presence of strong acid and alkali substances, even stainless steel joints may gradually be corroded, resulting in performance degradation or even failure. This corrosion not only affects the appearance of the joint, but more importantly, it weakens its structural strength, increases the risk of leakage, and may eventually lead to operational failure of the entire system, causing economic losses and even safety hazards. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a stainless steel joint anti-corrosion device that can overcome the above problems or at least partially solve the above problems.

[0005] The utility model is realized as follows: a stainless steel joint anti-corrosion device comprises a valve, a pipe and a main body, wherein one end of the valve contacts the pipe, the inner wall of the main body contacts the surface of the pipe, a fixing device is provided at the front end of the main body, and an auxiliary mechanism is provided at the front end of the fixing device;

[0006] The fixing device is used to fix the main body;

[0007] The auxiliary mechanism is used to protect the fixing device.

[0008] The cam is secured to the bottom of the body with a spring that is secured to the bottom of the body and has a spring that allows the cam to slide against the bottom of the body to move relative to the top of the body.

[0009] In order to further improve the protection effect, preferably, the auxiliary mechanism includes a movable groove, a protective box and a limit plate. The two movable grooves are respectively opened on the upper and lower sides of the main body. The inner wall of one end of the movable groove is fixedly connected to the surface of the limit plate. The surface of the limit plate contacts the surface of one side of the protective box. The setting of the limit plate is the end point of the sliding stroke of the protective box to ensure that the protective box can be accurately positioned in the correct position. By pushing the protective box along the movable groove until it contacts the limit plate at one end of the movable groove, effective covering of the fixed block and the mating block can be achieved, which not only provides an extra layer of physical protection for the stainless steel joint, reduces the influence of external environmental factors on the joint part, thereby enhancing the anti-corrosion effect. At the same time, this sliding installation method also makes the installation and disassembly of the protective box easier, which is convenient for daily maintenance and inspection.

[0010] In order to improve the convenience of operation, preferably, two auxiliary rods are respectively provided on the surfaces of the two limit rods, and the surfaces of the auxiliary rods are slidably connected to the surfaces of the mounting blocks through sliding grooves. The surfaces of the two limit rods are fixedly connected to the inner walls of the two auxiliary rods. The sliding connection between the auxiliary rods and the mounting blocks allows the user to manually operate the auxiliary rods to make the auxiliary rods translate along the sliding grooves on the mounting blocks. In this way, the user can more conveniently control the movement of the limit rods, that is, when it is necessary to release the fixing effect of the limit rods on the joints, it is only necessary to simply push the auxiliary rods to achieve the movement of the limit rods, thereby releasing their restriction on the connecting rods.

[0011] In order to improve the stability of the fixation, preferably, the lower end surfaces of the two fixing blocks are in contact with the upper end surfaces of the two matching blocks, the surface of the connecting rod is slidably connected to the inner wall of the matching block, the surface of the limiting rod is slidably connected to the surface of the connecting rod, the two ends of the spring are fixedly connected to the opposite side surfaces of the two limiting rods, and the surface of the connecting rod is slidably connected to the inner wall of the matching block, so that the connecting rod can slide freely in the matching block, so that when the device is closed, the connecting rod can be smoothly inserted into the matching block to achieve rapid assembly, and when disassembly is required, the connecting rod can be easily withdrawn from the matching block, realizing rapid disassembly of the device, and the limiting rod The surface is slidingly connected to the surface of the connecting rod, further ensuring the stable position of the connecting rod in the matching block. At the same time, the limit rod can move along with the connecting rod during the insertion of the connecting rod into the matching block, and finally stay in the appropriate position to prevent the connecting rod from being displaced or loosened due to vibration or other external forces during use. The two ends of the spring are fixedly connected to the opposite side surfaces of the two limit rods, so that the limit rod can be maintained in the preset initial position when there is no external force. When the locking state of the connecting rod needs to be released, the position of the limit rod can be temporarily changed by applying external force to compress the spring, thereby releasing the connecting rod, which is convenient for disassembly and maintenance of the device.

[0012] In order to improve the anti-corrosion effect, preferably, one side surface of the protective box is slidably connected to the inner wall of the movable groove. By slidably connecting the one side surface of the protective box to the inner wall of the movable groove, the protective box can be effectively prevented from being offset or falling off due to external factors in the working state, ensuring that the protective box is always in the correct position during use, ensuring its effective protection of the fixed block and the mating block, thereby enhancing the anti-corrosion effect.

[0013] In order to improve the stability of the device, preferably, the limit rod surface is slidably connected to the lower end surface of the main body through a slide groove, and the two ends of the mounting block are fixedly connected to the two mating block surfaces, and the two ends of the mounting block are fixedly connected to the two mating block surfaces, ensuring a firm connection between the mounting block and the mating block, and ensuring that during use, even if subjected to external vibration or other external forces, the connection between the mounting block and the mating block will not loosen or dislocate, thereby ensuring the stability of the entire device.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model is provided with a fixing device, an auxiliary mechanism, a limit rod, a connecting rod, a mounting block and a protective box. The fixing device is used to fix the main body, and the auxiliary mechanism is used to protect the fixing device. The surface of the movable rod is slidably connected with the inner surface of the spring, so that in the closed state, the spring can give the limit rod a certain elastic force to make it close to the connecting rod, further strengthening the fixing effect of the device and preventing loosening due to vibration or external impact, thereby effectively avoiding the risk of corrosion of the joint due to long-term exposure to the outside. The mounting block is set at the lower end of the main body and ensures the tightness of the device in the closed state through the interaction between the limit rod and the connecting rod. The setting of the limit plate is the end point of the sliding stroke of the protective box to ensure that the protective box can be accurately positioned in the correct position. By pushing the protective box along the movable groove until it contacts the limit plate at one end of the movable groove, effective covering of the fixing block and the matching block can be achieved. It not only provides an extra layer of physical protection for the stainless steel joints, reducing the impact of external environmental factors on the joints, thereby enhancing the anti-corrosion effect, but also this sliding installation method makes the installation and disassembly of the protective box easier, facilitating daily maintenance and inspection work, and solves the problem that although existing stainless steel joints are widely used in many industrial fields due to the corrosion resistance of the material itself, they still face potential corrosion risks over time due to the lack of special anti-corrosion devices. Especially in some extreme environments, such as high humidity, salt spray or the presence of strong acid and alkali substances, even stainless steel joints may gradually be corroded, resulting in their performance degradation or even failure. This corrosion will not only affect the appearance of the joint, but more importantly, it will weaken its structural strength, increase the risk of leakage, and ultimately may lead to operational failure of the entire system, causing economic losses and even safety hazards.

[0022] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown, an anti-corrosion device for a stainless steel joint provided by an embodiment of the present invention includes a valve 4, a pipe 5 and a main body 6.

The fixing device 1 is used to fix the main body 6, and the auxiliary mechanism 2 is used to protect the fixing device 1. The fixing device 1 includes a fixing block 101, a limiting rod 102, a connecting rod 103, a matching block 104, a mounting block 105, a movable rod 106 and a spring 107. The two fixing blocks 101 are respectively arranged on both sides of the upper end of the main body 6, and the two matching blocks 104 are respectively arranged on both sides of the lower end of the main body 6.

The mounting block 105 is arranged at the lower end of the main body 6, and the surface of the movable rod 106 is slidably connected to the inner surface of the spring 107, so that in the closed state, the spring 107 can give the limit rod 102 a certain elastic force, so that it is close to the connecting rod 103, further strengthening the fixing effect of the device and preventing loosening due to vibration or external impact, thereby effectively avoiding the risk of corrosion of the joint due to long-term exposure to the outside. The mounting block 105 is arranged at the lower end of the main body 6, and through the mutual engagement of the limit rod 102 and the connecting rod 103 The function is to ensure the tightness of the device in the closed state. The auxiliary mechanism 2 includes a movable groove 201, a protective box 202 and a limit plate 203. The two movable grooves 201 are respectively opened on the upper and lower sides of the main body 6. The inner wall of one end of the movable groove 201 is fixedly connected to the surface of the limit plate 203. The surface of the limit plate 203 contacts the surface of one side of the protective box 202. The setting of the limit plate 203 is the end point of the sliding stroke of the protective box 202, ensuring that the protective box 202 can be accurately positioned in the correct position. By pushing the protective box 202 along the movable groove 201 until it contacts the limit plate 203 at one end of the movable groove 201, effective coverage of the fixed block 101 and the matching block 104 can be achieved, which not only provides an additional layer of physical protection for the stainless steel joint, The influence of external environmental factors on the joint parts is reduced, thereby enhancing the anti-corrosion effect. At the same time, this sliding installation method also makes the installation and disassembly of the protective box 202 easier, and is convenient for daily maintenance and inspection work. Two auxiliary rods 3 are respectively provided on the surfaces of the two limit rods 102. The surfaces of the auxiliary rods 3 are slidably connected to the surfaces of the mounting blocks 105 through sliding grooves. The surfaces of the two limit rods 102 are fixedly connected to the inner walls of the two auxiliary rods 3. The sliding connection between the auxiliary rods 3 and the mounting blocks 105 allows the user to manually operate the auxiliary rod 3 so that the auxiliary rod 3 moves horizontally along the sliding groove on the mounting blocks 105. In this way, the user can more conveniently control the movement of the limit rod 102, that is, when it is necessary to release the fixing effect of the limit rod 102 on the joint,Simply push the auxiliary rod 3 to achieve the movement of the limiting rod 102, thereby releasing its restriction on the connecting rod 103. The lower end surfaces of the two fixed blocks 101 are in contact with the upper end surfaces of the two matching blocks 104. The surface of the connecting rod 103 is slidably connected to the inner wall of the matching block 104. The surface of the limiting rod 102 is slidably connected to the surface of the connecting rod 103. The two ends of the spring 107 are fixedly connected to the opposite side surfaces of the two limiting rods 102. The surface of the connecting rod 103 is slidably connected to the inner wall of the matching block 104, so that the connecting rod 103 can slide freely in the matching block 104, so that when the device is closed, the connecting rod 103 can be smoothly inserted The connection rod 103 is fastened to the mating block 104 to achieve quick assembly. When disassembly is required, the connecting rod 103 can be easily withdrawn from the mating block 104, thereby achieving quick disassembly of the device. The surface of the limiting rod 102 is slidably connected to the surface of the connecting rod 103, further ensuring the stability of the position of the connecting rod 103 in the mating block 104. At the same time, the limiting rod 102 can move along with the process of the connecting rod 103 being inserted into the mating block 104, and finally stay in the appropriate position to prevent the connecting rod 103 from being displaced or loosened due to vibration or other external forces during use. The two ends of the spring 107 are fixedly connected to the opposite side surfaces of the two limiting rods 102 When the locking state of the connecting rod 103 needs to be released, the position of the limiting rod 102 can be temporarily changed by applying external force to compress the spring 107, thereby releasing the connecting rod 103, which is convenient for disassembly and maintenance of the device. The surface of one side of the protective box 202 is slidably connected to the inner wall of the movable groove 201. By slidingly connecting the surface of one side of the protective box 202 to the inner wall of the movable groove 201, the protective box 202 can be effectively prevented from being deflected or falling off due to external factors in the working state, ensuring that the protective box 202 is always in a locked state during use. The correct position ensures effective protection for the fixing block 101 and the mating block 104, thereby enhancing the anti-corrosion effect. The surface of the limiting rod 102 is slidably connected to the lower end surface of the main body 6 through a sliding groove. The two ends of the mounting block 105 are fixedly connected to the surfaces of the two mating blocks 104. The two ends of the mounting block 105 are fixedly connected to the surfaces of the two mating blocks 104, ensuring a stable connection between the mounting block 105 and the mating blocks 104. Even if they are subjected to external vibration or other external forces during use, the connection between the mounting block 105 and the mating block 104 will not loosen or dislocate, thereby ensuring the stability of the entire device.

[0024] The working principle of this utility model:

[0025] When in use, first, since the rear end of the main body 6 is tightly connected by the rotating shaft, the main body 6 can rotate freely, thereby realizing flexible operation. Then, the main body 6 is closed, and the connecting rod 103 in the inner wall of the fixed block 101 will be inserted into the matching block 104. At the same time, since the limiting rod 102 is pre-set in the matching block 104, when the connecting rod 103 enters the matching block 104, it will be squeezed synchronously by the connecting rods 103 on both sides, so that the two limiting rods 102 in the mounting block 105 move toward the middle of the mounting block 105. In this way, the limiting rod 102 will contact the connecting rod 103, thereby achieving a fixing effect. In this state, the limiting rod 102 can effectively prevent the connecting rod 103 from loosening when fixed under the action of the spring 107 and the movable rod 106, thereby avoiding loosening of the device. This causes the joint to be corroded. After the fixing block 101 contacts the mating block 104 and completes the initial fixation, the next step is to push the protective box 202 along the movable groove 201 until it contacts the limit plate 203 at one end of the movable groove 201. In this way, the fixing block 101 and the mating block 104 can be effectively protected, further enhancing the anti-corrosion effect. When the joint needs to be inspected and maintained, it is only necessary to remove the protective box 202, and then pinch the auxiliary rod 3 so that the auxiliary rod 3 drives the limit rod 102, and at the same time squeeze the spring 107 and retract it into the installation box. In this way, the connecting rod 103 can be pulled out from the mating block 104, so that the main body 6 can be opened, which is convenient for subsequent inspection and maintenance work. In this way, the operation of the entire device becomes very convenient, and the stability and reliability of the device are greatly improved.
