Description

Technical Field

[0001] This invention relates to the field of industrial pipeline technology, and more specifically to a multifunctional detachable stainless steel valve insulation sleeve. Background Technology

[0002] Existing pipeline protection devices mostly employ a single spring-type pressure relief structure. When the pressure exceeds the limit, pressure is relieved by spring compression. However, this method suffers from problems such as unreliable reset and slow response speed. Especially under continuous high-pressure conditions, the spring is prone to fatigue deformation, causing the pressure relief port to fail to close completely, posing a risk of media leakage. In addition, traditional devices usually require manual reset, making them unsuitable for unattended or high-risk environments.

[0003] Industrial piping systems employ a variety of flange specifications, and traditional fixing devices often use rigid bolt connections. This necessitates custom-designed installation components for different specifications, resulting in high replacement costs and low operational efficiency. Some adjustable clamps utilize screw and nut drives, which have drawbacks such as limited adjustment range and rapid mechanical wear, failing to meet the demands of frequent replacements.

[0004] Existing pneumatic transmission devices mostly employ direct mechanical linkages or gear drives, which are prone to corrosion and jamming in corrosive environments. Furthermore, the structure of directly driving the piston with high-pressure gas suffers from low energy conversion efficiency and high noise levels, and requires an additional lubrication system, increasing maintenance complexity. Traditional transmission methods cannot achieve non-contact power transmission, limiting the application of these devices in special environments such as explosion-proof and cleanroom settings. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a multifunctional detachable stainless steel valve insulation sleeve with small or no feeding deviation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] As a further improvement of the present invention, it includes a protective sleeve and a fixing seat arranged symmetrically, and a positioning bolt for fixing the protective sleeve through the fixing seat. The protective sleeve is provided with a venting cylinder and includes a protective component. The protective component includes a venting component disposed on the inner wall of the venting cylinder. The venting component includes an abutment rod.

The support member includes a support plate threaded onto the outer walls of the two protective sleeves. A sliding groove is provided on one side of the support plate in a circumferentially evenly distributed manner along the axis of the support plate.

[0015] The support member is rotatably provided with a sliding opening and closing member, which can control the opening and closing of the opening when the support member rotates in the forward and reverse directions.

[0016] As a further improvement of the present invention, the sliding opening and closing component includes a turntable rotatably disposed on one side of the bearing plate, the turntable having an opening and a limiting groove, a plurality of positioning posts being slidably disposed in the limiting groove, the plurality of positioning posts being evenly distributed circumferentially along the axis of the turntable, a slider being fixedly disposed on each positioning post, a plate being fixedly disposed on each slider, and each plate being slidably installed in each sliding groove, the turntables symmetrically disposed on both sides of the protective sleeve being fixedly connected by connecting rods and rotating synchronously.

[0017] As a further improvement of the present invention, the transmission mechanism includes a mounting plate fixedly disposed on the outer wall of the venting cylinder, a connecting rod fixedly disposed on the top outer wall, a pressure rod fixedly disposed at the bottom end of the other end of the connecting rod, and the lower end of the pressure rod penetrating the mounting plate;

[0018] The mounting plate is provided with a pneumatic valve assembly that converts gas pressure into rotational power after the gas flows out of the protective sleeve. The mounting plate is also provided with a transmission assembly for converting the rotational power of the pneumatic valve assembly into a driving force for opening the mounting assembly.

[0019] As a further improvement of the present invention, the pneumatic valve assembly includes a mounting ring fixedly disposed on the inner wall of the mounting plate, an air collecting cylinder fixedly disposed within the mounting ring, an air pressure channel opened on the air collecting cylinder, a spring fixedly disposed within the air pressure channel, a flow-blocking ball fixedly disposed on the spring, a protrusion also disposed within the air pressure channel, the flow-blocking ball normally tightly fitting against the protrusion to form a seal, a sliding seat also slidably disposed within the air channel, a transmission rod rotatably disposed inside the sliding seat, an abutment post fixedly disposed at the bottom end of the sliding seat, a diaphragm fixedly disposed on the outer wall of the sliding seat, the periphery of the diaphragm sealingly connecting to the upper surface of the air collecting cylinder, an exhaust plate also disposed within the air collecting cylinder, the exhaust plate having a port for discharging gas.

[0020] As a further improvement of the present invention, the transmission mechanism includes a first bevel gear rotatably mounted on the upper surface of the mounting ring via a fixed plate, the other end of the transmission rod being eccentrically rotatably connected to the first bevel gear, a second bevel gear rotatably mounted on the mounting ring via a fixed plate and perpendicularly distributed to the first bevel gear, the first bevel gear meshing with the second bevel gear, a third magnet fixedly mounted on the other end of the second bevel gear, a fourth magnet rotatably mounted on the mounting plate via a fixed plate, one end of the fourth magnet magnetically coupling the third magnet, and a drive disk fixedly mounted on the other end of the fourth magnet.

[0022] As a further improvement of the present invention, it includes a valve body, and a wastewater inlet and a wastewater outlet respectively disposed on the valve body;

[0023] The valve body includes a valve seat, a valve body disposed on the valve seat, and a gate valve disposed at one end of the valve seat.

[0024] The beneficial effects of this invention are:

[0025] 1. This invention utilizes a dual pressure relief mechanism through the coordinated repulsive force of the valve disc and the magnet. When the gas pressure inside the pipeline exceeds a preset threshold, the high-pressure gas pushes the valve disc upward to overcome the spring preload. At the same time, magnet one (N / S poles facing upward) and magnet two (N / S poles facing upward) form a repulsive force field with the same poles, which keeps the valve stem stably in the open state, ensuring continuous release of high-pressure gas and effectively preventing the pressure vessel from overpressure explosion.

[0026] 2. This invention utilizes a rotatable and adjustable sliding block structure to quickly adapt to the fixed outer diameter of flanges of different specifications. Eight sets of evenly distributed sliding grooves on the circumference of the bearing plate, together with the slider, form a planetary transmission mechanism. When the turntable rotates, the plate drives the slider to move radially along the sliding grooves via limiting grooves, achieving both the maximum expansion diameter and the minimum contraction diameter. A symmetrically arranged linkage synchronous transmission structure ensures synchronized adjustment of the openings on both sides. Combined with the quick-release design of the positioning bolts, it can adapt to flange replacement needs under different working conditions.

[0027] 3. This invention uses a pneumatic valve assembly to convert high-pressure gas pressure into rotational power, and uses magnetic coupling to drive the non-contact opening and closing of the mounting components. When the gas pressure inside the venting cylinder reaches a certain level, the diaphragm moves the sliding seat up and down, squeezing the flow-blocking ball and compressing the spring, which in turn drives the transmission rod to eccentrically drive the bevel gear set, converting linear motion into rotational power. The drive disc rotates the turntable via belt drive, achieving automated control of the opening adjustment and reducing human error. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown herein can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0038] Example 1

[0039] refer to Figures 1-8The figure shows a specific embodiment of the multifunctional detachable stainless steel valve insulation sleeve of the present invention, which includes a protective sleeve 101 and a fixing seat 102 arranged symmetrically, and a positioning bolt 104 for fixing the protective sleeve 101 through the fixing seat 102. The protective sleeve 101 is provided with a venting cylinder, including a protective component 100. The protective component 100 includes a venting component 103 disposed on the inner wall of the venting cylinder. The venting component 103 includes an abutment rod 1039. The venting component 103 is used to push out the abutment rod 1039 after being subjected to a gas pressure exceeding a threshold and to maintain the pushed-out state.

[0040] The venting assembly 103 includes a valve stop assembly, which includes a baffle plate 1032 symmetrically fixedly installed on the inner wall of the venting cylinder. A valve seat 1034 is fixedly installed on the baffle plate 1032. A through hole is also provided on the baffle plate 1032. A valve stem 1036 is slidably provided on the valve seat 1034. A valve disc 1033 is fixedly provided at the bottom end of the valve stem 1036. Under normal conditions, the valve disc 1033 is tightly fitted to the through hole of the baffle plate 1032. A cover 1031 is also provided at the upper end of the baffle plate 1032. The top of the cover 1031 is threadedly connected to the top of the venting cylinder.

[0041] The venting assembly 103 also includes a control assembly, which is used to drive the valve stem 1036 to push upward and maintain the pushed-out state when the valve disc 1033 receives gas pressure, so that the valve disc 1033 does not fit with the through hole of the baffle plate 1032.

[0042] Under normal conditions, when the gas pressure inside the venting cylinder is within a safe threshold range, the valve disc 1033, under its own weight, is tightly pressed against the through hole of the baffle plate 1032. At this time, the valve stem 1036 is in a relatively low position, and the magnet 1 inside the valve stem 1036 maintains a certain initial distance from the magnet 1037 on the mounting base 1035. The spring sleeved on the outer wall of the abutment rod 1039 is in a naturally extended state, and the abutment rod 1039 is located in its initial position within the mounting sleeve 1038 under the action of the spring. The entire device is in a sealed state, preventing gas from leaking out from the through hole of the baffle plate 1032.

[0043] Furthermore, as the gas pressure inside the venting cylinder gradually increases and exceeds a preset threshold, the upward pressure generated by the high-pressure gas acts on the valve disc 1033. This pressure begins to overcome the resistance, such as the weight of the valve disc 1033 and the friction between the valve stem 1036 and the valve seat 1034. As the pressure continues to increase, the valve disc 1033 begins to move upward. Since the valve disc 1033 and the valve stem 1036 are fixedly connected, the valve stem 1036 also moves upward along with the valve disc 1033. Simultaneously, the magnet inside the valve stem 1036 also rises synchronously with the valve stem 1036.

[0044] The control component includes a mounting base 1035 disposed on the inner wall of the cover 1031, a magnet 1037 disposed on the mounting base 1035, and a mounting sleeve 1038 coaxially distributed with the other end of the valve stem 1036 disposed on the cover 1031. The abutment rod 1039 is slidably disposed on the inner wall of the mounting sleeve 1038, and a spring is sleeved on the outer wall of the abutment rod 1039. The spring is used to reset the abutment rod 1039 when it is not compressed. A magnet is disposed inside the valve stem 1036.

[0045] The magnetic poles of magnet one are all in the direction of "N at the top and S at the bottom"; the magnetic poles of magnet two are also in the direction of "N at the top and S at the bottom".

[0046] As the valve stem 1036 rises, the distance between magnet one and magnet two 1037 gradually decreases. Since the magnetic poles of magnet one and magnet two 1037 are both "N at the top and S at the bottom," according to the principle of repulsion between like poles, the repulsive force between them increases rapidly as the distance decreases. When this repulsive force exceeds the sum of the weight of the valve disc 1033 and other possible resistances, the repulsive force between magnet one and magnet two 1037 will stably hold the valve stem 1036 in the extended position. At this time, the valve disc 1033 is completely separated from the through hole of the baffle plate 1032, forming a continuous leakage channel between them. High-pressure gas can then escape from the leakage cylinder through this channel, thereby reducing the gas pressure inside the leakage cylinder and the protective sleeve 101.

[0047] Furthermore, when the repulsive force between magnet one and magnet two 1037 keeps valve stem 1036 stably in the extended position, the continuous pressure of valve stem 1036 pushing outwards acts on abutting rod 1039. At this time, abutting rod 1039 begins to overcome the spring force and slides outwards within mounting sleeve 1038, gradually compressing the spring. The outward pushing action of abutting rod 1039 visually indicates that the gas pressure inside the venting cylinder has exceeded the threshold and that a venting operation is underway. As long as the gas pressure inside the venting cylinder is higher than the threshold, abutting rod 1039 will remain in the extended position, and valve stem 1036 will also remain in the extended position due to the repulsive force between magnet one and magnet two 1037, and the venting process will continue.

[0048] Furthermore, as the leakage process proceeds, if it is necessary to restore the device to its normal sealed state, the abutment rod 1039 needs to be pressed manually so that magnet one overcomes the upward repulsive force of magnet two 1037. When magnet one passes the equilibrium point of magnet two 1037, magnet two 1037 applies a downward repulsive force to magnet one, so that valve disc 1033 is tightly fitted with the through hole of baffle plate 1032, thus waiting for the next possible pressure change.

[0049] In summary, this device cleverly utilizes the principle of like poles repelling each other in magnets and the elastic properties of springs to achieve automatic control and regulation of gas pressure within the venting cylinder. When the gas pressure exceeds a threshold, the venting channel can be opened promptly to release the pressure, and the venting status is visually displayed through magnetic locking and the action of the abutment rod. After the pressure returns to normal, it can be manually reset to re-establish a seal, ensuring the safe and stable operation of the device, reducing manual intervention and maintenance costs, and improving the reliability and service life of the device.

[0050] Example 2

[0051] Please refer to Figures 1-8 This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0052] As a further technical solution of this embodiment, there are two mounting components 200. The two mounting components 200 are symmetrically and detachably disposed at both ends of the two protective sleeves 101. The mounting components 200 are used to fix flanges of different diameters by changing the size of the opening.

[0053] A transmission assembly 300 is fixedly disposed on the outer wall of the venting cylinder. The transmission assembly 300 includes a magnet 309, one end of which penetrates the outer wall of the venting cylinder and communicates with the interior of the venting assembly 103. The transmission assembly 300 converts the pressure of the high-pressure gas flowing out of the venting assembly 103 into rotational motion power through the magnet 309, and is used to control the opening and closing of the opening of the mounting assembly 200.

[0054] The mounting assembly 200 includes a support member 202 that can be detachably mounted on the outer wall of the protective sleeve 101. The support member 202 includes a support plate 2021 threadedly mounted on the outer walls of the two protective sleeves 101. A sliding groove is provided on one side of the support plate 2021 and is evenly distributed circumferentially along the axis of the support plate 2021.

[0055] The support member 202 is rotatably provided with a sliding opening and closing member 201, which can control the opening and closing of the opening when the support member 202 rotates forward and backward.

[0056] The sliding opening and closing component 201 includes a turntable 2011 rotatably disposed on one side of the bearing plate 2021. The turntable 2011 has an opening and a limiting groove 2012. Multiple positioning posts 2015 are slidably disposed in the limiting groove 2012. The multiple positioning posts 2015 are evenly distributed circumferentially along the axis of the turntable 2011. A slider 2013 is fixedly disposed on each positioning post 2015. A plate 2014 is fixedly disposed on each slider 2013. Each plate 2014 is slidably installed in each sliding groove 2022. The turntables 2011 symmetrically disposed on both sides of the protective sleeve 101 are fixedly connected by connecting rods and rotate synchronously.

[0057] When flanges of different diameters need to be fixed, the bearing plate 2021 is first installed at both ends of the protective sleeve 101 via threads. Rotating the turntable 2011 causes the limiting groove 2012 on the turntable 2011 to move the positioning pin 2015 circumferentially. The positioning pin 2015 is connected to the plate 2014 via a slider 2013, and the plate 2014 slides radially within the sliding groove 2022 of the bearing plate 2021. When the turntable 2011 rotates clockwise, the limiting groove 2012 forces the positioning pin 2015 to move towards the center, causing the plate 2014 to contract and the opening to decrease; when the turntable 2011 rotates counterclockwise, the positioning pin 2015 moves towards the edge, and the plate 2014 expands, increasing the opening. The symmetrically arranged turntables 2011 rotate synchronously via connecting rods, ensuring consistent opening adjustment on both sides and achieving clamping and fixing of flanges of different diameters.

[0058] The transmission assembly 300 includes a mounting plate 301 fixedly disposed on the outer wall of the effluent cylinder, a connecting rod 302 fixedly disposed on the top outer wall of the 1089, a pressure rod 303 fixedly disposed at the bottom of the other end of the connecting rod 302, and the lower end of the pressure rod 303 penetrating through the mounting plate 301.

[0059] The mounting plate 301 is provided with a pneumatic valve assembly 308 that converts gas pressure into rotational power after the gas flows out of the protective sleeve 101. The mounting plate 301 is also provided with a transmission assembly for converting the rotational power of the pneumatic valve assembly 308 into a driving force for opening the opening of the mounting assembly 200.

[0060] The pneumatic valve assembly 308 includes a mounting ring 3081 fixedly mounted on the inner wall of the mounting plate 301. An air collecting cylinder 3082 is fixedly mounted inside the mounting ring 3081. An air pressure channel is provided on the air collecting cylinder 3082. A spring 3083 is fixedly mounted inside the air pressure channel. A flow-blocking ball 3084 is fixedly mounted on the spring 3083. A protrusion is also provided inside the air pressure channel. The flow-blocking ball 3084 normally fits tightly against the protrusion to form a seal. A sliding seat 3086 is also slidably mounted inside the air channel. A transmission rod 3089 is rotatably mounted inside the sliding seat 3086. An abutment post 3088 is fixedly mounted at the bottom end of the sliding seat 3086. A diaphragm 3087 is fixedly mounted on the outer wall of the sliding seat 3086. The periphery of the diaphragm 3087 is sealed to the upper surface of the air collecting cylinder 3082. An exhaust plate 3085 is also provided inside the air collecting cylinder 3082. The exhaust plate 3085 has an opening for venting gas.

[0061] The transmission mechanism includes a bevel gear 304 rotatably mounted on the upper surface of the mounting ring 3081 via a fixed plate. The other end of the transmission rod 3089 is eccentrically rotatably connected to the bevel gear 304. A bevel gear 305, perpendicularly distributed to the bevel gear 304, is also rotatably mounted on the mounting ring 3081 via a fixed plate. The bevel gear 304 meshes with the bevel gear 305. A magnet 306 is fixedly mounted on the other end of the bevel gear 305. A magnet 309 is rotatably mounted on the mounting plate 301 via a fixed plate. One end of the magnet 309 is magnetically coupled to the magnet 306. A drive disk 307 is fixedly mounted on the other end of the magnet 309.

[0062] The drive disk 307 is connected to one of the turntables 2011 via belt drive.

[0063] When the venting assembly 103 begins to release high-pressure gas, the abutment rod 1039 is already extended. The extended abutment rod 1039, through the connecting rod 302, drives the pressure rod 303 to rise. The raised pressure rod 303 does not seal the hose connected to the body of 308, allowing gas to enter the pneumatic valve assembly 308 of the transmission assembly 300. The high-pressure gas first acts on the diaphragm 3087 inside the gas collecting cylinder 3082. Under the pressure of the gas, the diaphragm 3087 bulges upwards, and the gas is discharged through the exhaust hole on the exhaust plate 3085. At this time, the diaphragm drives the sliding seat 3086 to move downwards, compressing the flow-blocking ball 3084. The flow-blocking ball 3084 compresses the spring 3083, expelling the internal gas through the exhaust channel. When the sliding seat 3086 moves up and down, it can drive the transmission rod 3089 to perform eccentric circular motion, and the transmission rod 3089 drives the bevel gear 304 to rotate. Bevel gear 304 meshes with vertically distributed bevel gear 305, changing the rotation direction by 90 degrees before transmitting the rotation to magnet 306. Magnet 306 is magnetically coupled to magnet 409, driving magnet 409 to rotate synchronously. The drive disc 307 at the other end of magnet 409 drives turntable 2011 to rotate via belt drive, thereby controlling the automatic opening of the opening of the mounting assembly 200. When the gas pressure decreases, spring 3083 pushes sliding seat 3086 to reset, flow-blocking ball 3084 re-seals, and transmission assembly 300 stops operating.

[0064] When it is necessary to close the mounting components 200 on both sides, the drive disk 307 needs to be manually rotated in the reverse direction. The drive disk 307 drives 2011 to rotate in the reverse direction through the belt, thereby closing the mounting components 200 again.

[0065] It also includes a valve body, and a wastewater inlet and a wastewater outlet respectively provided on the valve body;

[0066] The valve body includes a valve seat, a valve body disposed on the valve seat, and a gate valve disposed at one end of the valve seat.

[0067] In summary, this device converts the linear pressure of high-pressure gas into rotational power through the pneumatic valve assembly 308. After speed change via bevel gear 304 and bevel gear 305, the non-contact coupling transmission of magnet 306 and magnet 409 drives the turntable 2011 of the mounting assembly 200 to automatically adjust and open the opening. The planetary transmission structure of the sliding opening and closing component 201 allows the plate 2014 to precisely adapt to flanges of different diameters, and the synchronous connecting rod design ensures uniform clamping force on both sides. The entire system achieves fully automatic flange fixing under pressure drive, avoiding the wear problems of traditional mechanical transmission and improving the reliability and adaptability of the device under complex working conditions.
