Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, specifically a pipeline-type breather valve. Background Technology

[0002] Pipeline breather valves are critical safety protection devices widely used in the vapor phase pipelines on top of storage tanks in the petroleum, chemical, and pharmaceutical industries. Their core function is to automatically maintain a dynamic balance between the internal pressure of the storage tank and the external atmospheric pressure, thereby ensuring the safety of the tank when storing or transporting volatile liquids. During operation, when the internal pressure of the storage tank exceeds the set value due to material feeding or an increase in ambient temperature, the breather valve's exhalation valve disc automatically opens, releasing excess oil-gas mixture and preventing the tank from bursting due to overpressure—this is the "exhalation" process. Conversely, when the storage tank experiences negative pressure due to material discharge or a drop in temperature, the suction valve disc opens, drawing in outside air to balance the internal and external pressures, avoiding the risk of the tank collapsing—this is the "suction" process. Through this automatic "breathing" regulation, pipeline breather valves not only effectively ensure the structural safety of the storage tank but also significantly reduce material evaporation losses caused by direct discharge, combining safety, environmental protection, and economic value. Their design typically includes flame arresters to prevent external flames from propagating back into the tank, making them an indispensable safety accessory in modern industrial storage and transportation systems.

[0003] However, existing technologies still have significant shortcomings, such as:

[0004] The fundamental function of a breather valve in an acid production pipeline is to maintain pressure balance. However, during the acid discharge process, impurities may remain in the breather valve. If these impurities become blocked, the breather channel is cut off. When the internal pressure of the pipeline or related equipment increases due to temperature rise or process fluctuations, it cannot properly discharge air and relieve pressure, which may lead to a sharp increase in pressure, exceeding the design pressure limit of the equipment, and posing a risk of equipment cracking or even explosion. Conversely, when cooling or pumping out materials, a negative pressure is formed inside, and the breather valve cannot draw in air to compensate. The equipment may be crushed by atmospheric pressure, resulting in collapse and deformation. Therefore, we propose a pipeline-type breather valve. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline-type breather valve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pipeline-type breather valve includes: a valve tank, a vacuum valve disposed on the top of the inner wall of the valve tank, a top flange fixedly connected to the top of the vacuum valve, a pressure relief valve for venting is disposed on one side of the top flange, an anti-clogging component for preventing clogging is disposed on the inner wall of the valve tank, and a movable component for cleaning is disposed on the surface of the anti-clogging component.

[0008] Preferably, the anti-clogging component includes a motor stabilizing plate fixed to the top of the top flange, a drive motor fixedly connected to one side of the motor stabilizing plate, a connecting shaft provided at the bottom of the drive motor, and a floating ball slidably connected to the surface of the connecting shaft.

[0009] Preferably, mounting brackets are fixedly connected to both sides of the bottom of the inner wall of the valve tank, and a limiting frame is fixedly connected between multiple mounting brackets, with the connecting shaft disposed on the inner wall of the limiting frame.

[0010] Preferably, an acid production pipeline connecting pipe is fixedly connected to the bottom of the valve tank, and multiple anti-clogging scrapers are fixedly connected to the bottom surface of the connecting shaft, the anti-clogging scrapers being disposed on the inner wall of the acid production pipeline connecting pipe.

[0011] Preferably, the movable component includes a connecting rotating block fixed to the surface of the connecting rotating shaft, and a spiral rotating plate is fixedly connected to the surface of the connecting rotating block.

[0012] Preferably, connecting rotating plates are fixedly connected to both sides of the surface of the spiral rotating plate, and an inner wall scraper is fixedly connected between the multiple connecting rotating plates.

[0013] Preferably, a manual drain outlet is fixedly connected to one side of the acid production pipeline connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The anti-clogging component structure helps prevent blockage during the use of the entire device. The floating ball floats under the pressure of the acid-producing raw material water transported in the pipeline during the overall depressurization of the device. When it floats to the vacuum valve, it can block it. At this time, the pressure relief valve is activated to release the internal air, completing the basic depressurization function. During this process, impurities may remain in the acid-producing raw material water. At this time, the drive motor starts and drives the connecting shaft to rotate. This causes the anti-clogging scraper at the bottom of the connecting shaft to continuously rotate on the inner wall of the acid-producing pipeline connecting pipe, preventing impurities in the acid raw material from accumulating and adhering, which can cause blockage after long-term use. This further improves the functionality and safety of the device.

[0016] 2. The structure of the movable components helps the anti-clogging components operate, cleaning the inside of the valve tank. The connecting rotating block, in conjunction with the rotating shaft, drives the spiral plate to rotate. This rotation, combined with the centrifugal force of the water rushing up from inside the valve tank due to pressure, facilitates the outflow of subsequent water and prevents residual impurities from remaining inside the valve tank. Simultaneously, the rotating connecting block drives the connecting rotating plates on both sides to rotate, thereby causing the inner wall scraper to continuously scrape impurities from the bottom of the valve tank's inner wall. The centrifugal vortex generated by the rotating spiral plate prevents secondary adhesion and accumulation of impurities, thus further improving the functionality and safety of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A pipeline-type breather valve includes: a valve tank 1, a vacuum valve 2 disposed on the top of the inner wall of the valve tank 1, a top flange 3 fixedly connected to the top of the vacuum valve 2, a pressure relief valve 4 for venting is disposed on one side of the top flange 3, an anti-clogging component 5 for preventing clogging is disposed on the inner wall of the valve tank 1, and a movable component 6 for cleaning is disposed on the surface of the anti-clogging component 5.

[0026] In this embodiment, the valve tank 1, vacuum valve 2, and pressure relief valve 4 can be combined to release pressure in the acid production pipeline connected to the anti-clogging component 5, thereby completing the basic breathing valve function. The top flange 3 helps to stabilize the entire device from the top. The anti-clogging component 5 can clean impurities in the raw water that is drained during the depressurization of the acid production pipeline and prevent impurities in the water from adhering to its interior and causing blockage. Together with the movable component 6, it cleans the inside of the valve tank 1 to prevent impurities from adhering to its interior and causing blockage, thereby further improving the functionality and safety of the device.

[0027] The anti-clogging component 5 includes a motor stabilizing plate 501 fixed to the top of the top flange 3. A drive motor 502 is fixedly connected to one side of the motor stabilizing plate 501. A connecting shaft 503 is provided at the bottom of the drive motor 502. A floating ball 504 is slidably connected to the surface of the connecting shaft 503.

[0028] In this embodiment, the anti-clogging component 5 can use the motor stabilizing plate 501 to fix the drive motor 502 to the top of the top flange 3, providing lateral installation stability for the use of the drive motor 502. At the same time, the floating ball 504 can use its internal hollow structure to float up and block the vacuum valve 2 when it encounters the buoyancy of water, thus providing a trigger point for the use of the vacuum valve 2 and the pressure relief valve 4. The drive motor 502 can provide a basis for the rotation of the connecting shaft 503, while the floating ball 504 limits its internal position through the connecting shaft 503.

[0029] Mounting brackets 505 are fixedly connected to both sides of the bottom of the inner wall of valve tank 1. Limiting frames 506 are fixedly connected between multiple mounting brackets 505, and the connecting shaft 503 is set on the inner wall of the limiting frame 506.

[0030] In this embodiment, the mounting bracket 505, together with the limiting frame 506, limits the position of the connecting shaft 503 while preventing it from shifting due to the buoyancy of water entering during use, thereby further improving the overall functionality of the device.

[0031] The bottom of the valve tank 1 is fixedly connected to an acid production pipeline connecting pipe 507, and the bottom surface of the connecting shaft 503 is fixedly connected to multiple anti-clogging scrapers 508, which are disposed on the inner wall of the acid production pipeline connecting pipe 507.

[0032] In this embodiment, the acid production pipeline connecting pipe 507 is connected to the bottom of the valve tank 1, thereby connecting the entire device to the installation node of the acid production pipeline. During long-term use of the acid production pipeline, the air accumulated at the node will be discharged into the device through the acid production pipeline connecting pipe 507, thus providing a vent for depressurization inside the device. The anti-clogging scraper 508, under the action of the drive motor 502, scrapes the inner wall of the anti-clogging scraper 508 in real time, thereby preventing internal impurities from adhering to the inner wall of the acid production pipeline connecting pipe 507 and causing blockage when the acid water raw material transported by the acid production pipeline enters the device, further improving the overall safety of the device.

[0033] The active component 6 includes a connecting rotating block 601 fixed to the surface of the connecting rotating shaft 503, and a spiral rotating plate 602 is fixedly connected to the surface of the connecting rotating block 601.

[0034] In this embodiment, the connecting rotating block 601 can rotate under the action of the connecting rotating shaft 503, thereby driving the spiral rotating plate 602 to rotate continuously. This spiral rotation can maintain the internal vortex rotation of the acid water raw material, thereby maintaining the water flow while preventing impurities from adhering to the inner wall of the valve tank 1, further improving the functionality of the device.

[0035] Both sides of the spiral rotating plate 602 are fixedly connected to connecting rotating plates 603, and inner wall scrapers 604 are fixedly connected between multiple connecting rotating plates 603.

[0036] In this embodiment, the rotating connecting block 601 drives the connecting rotating plates 603 on both sides to rotate, thereby driving the inner wall scraper 604 to continuously scrape away impurities at the bottom of the inner wall of the valve tank 1. The centrifugal vortex generated by the rotation of the spiral rotating plate 602 can prevent impurities from adhering and accumulating again, thus preventing blockage and further improving the functionality and safety of the device.

[0037] A manual drain port 7 is fixedly connected to one side of the acid production pipeline connecting pipe 507.

[0038] In this embodiment, the manual drain port 7 can manually force the water inside the device to be discharged directly when needed, thereby helping staff to maintain the device and further improving the functionality and safety of the device.

[0039] Working principle: When the pressure inside the acid production pipeline increases due to temperature rise or process changes, the overpressured gas carries a small amount of acid raw material into the valve tank 1 through the acid production pipeline connecting pipe 507. Under pressure, the acid liquid level rises, and the resulting buoyancy pushes the floating ball 504 upward along the connecting shaft 503 until it closes the vacuum valve 2. At this time, the pressure relief valve 4 opens under pressure, releasing the overpressured gas, completing the exhalation process, and preventing overpressure in the pipeline.

[0040] When the temperature inside the pipeline drops or negative pressure is formed due to the output material, the external atmospheric pressure is higher than the internal pressure. The valve disc of vacuum valve 2 is sucked open, and external air enters the valve tank 1. The floating ball 504 falls under the action of gravity, completing the air intake process and balancing the pressure inside and outside the pipeline.

[0041] Throughout the operation, the drive motor 502 operates continuously or intermittently, with stable support provided by the motor stabilizing plate 501. The drive motor 502 drives the connecting shaft 503 to rotate, and the connecting shaft 503 is positioned by the mounting bracket 505 and the limiting frame 506 to ensure smooth rotation. The rotating connecting shaft 503 directly drives multiple anti-clogging scrapers 508 at its bottom to continuously scrape the inner wall of the acid production pipeline connecting pipe 507, preventing impurities in the acid from depositing and adhering, and fundamentally avoiding inlet blockage.

[0042] Simultaneously, the rotation of the connecting shaft 503 causes the connecting rotating block 601 fixed to its surface to rotate as well. The connecting rotating block 601 drives the spiral rotating plate 602 on it to rotate inside the valve tank 1, causing the acid entering the tank to swirl and using centrifugal force to prevent impurities from settling on the inner wall of the valve tank 1. The connecting rotating plates 603 fixed on both sides of the spiral rotating plate 602 rotate accordingly, driving the inner wall scraper 604 to rotate and scrape against the bottom of the inner wall of the valve tank 1, further removing any residue that may have accumulated. Periodically, a small amount of liquid that may have accumulated can be drained through the manual drain port 7 to complete maintenance.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
