Description

Technical Field

[0001] This utility model relates to the field of steam transportation technology, and in particular to a high-pressure steam overpressure early warning and high-stability gas supply device. Background Technology

[0002] Steam generators are used to produce high-pressure steam and deliver it to equipment that needs heating or uses steam. Pressure regulating valves are a common type of steam supply device that ensures high-pressure steam operates at the appropriate pressure in pipelines and prevents overpressure by regulating the pressure of the fluid.

[0003] Some gas supply systems use manual valves for venting control. In emergencies, these valves cannot be automatically opened via interlocking, easily leading to pipeline overpressure. This poses a significant safety hazard to the safe operation of high-pressure pipelines, causing substantial damage to equipment and potentially resulting in serious equipment and personal injury. Therefore, we propose a high-pressure steam overpressure early warning and high-stability gas supply device to address these problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a high-pressure steam overpressure early warning and high-stability gas supply device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure steam overpressure early warning and high-stability gas supply device, comprising a conveying pipe, a motor, an vent pipe, a force-bearing block, and a second guide rod. The upper end of the conveying pipe is connected to the vent pipe, and a hydraulic rod is installed inside the vent pipe. A closing seat is installed at the lower end of the hydraulic rod. A pressure sensor is installed inside one end of the conveying pipe. A sliding seat is installed on the inner wall of the lower end of the conveying pipe. A first guide rod is slidably installed inside the sliding seat. A force-bearing block and a cone plate are respectively installed at both ends of the first guide rod. A sliding sleeve is embedded inside the upper end of the conveying pipe. A second guide rod is slidably installed inside the sliding sleeve. A second limit ring is sleeved on the outer wall of the second guide rod. A second spring connected to the inner wall of the upper end of the second limit ring is installed at the upper end of the second limit ring. A contact sensor corresponding to the second guide rod is installed at the upper end of the conveying pipe.

[0006] When using the high-pressure steam overpressure early warning and high-stability gas supply device in this solution, the delivery pipe transports high-temperature and high-pressure steam. The steam is detected by a pressure sensor. When the pressure sensor detects a value that reaches a set threshold, it issues an alarm to the controller. Simultaneously, during the high-temperature and high-pressure steam transport process, it impacts a force block elastically supported on one side of the sliding sleeve by a spring. The force block compresses the spring, causing the guide rod to move. This movement then compresses the cone plate onto the guide rod. The guide rod then applies pressure to the spring through a limit ring, causing it to rise. When the contact head rises with the guide rod and contacts the contact sensor, the sensor alarms the controller. The controller, through its internal processing and control module, controls the operation of the motor and hydraulic rod. The motor drives the valve core to rotate, adjusting the opening of the delivery pipe. The hydraulic rod drives the closing seat to descend, entering the delivery pipe and connecting it to the vent pipe, thus allowing the high-temperature steam to release pressure through the vent pipe.

[0007] Preferably, the upper end of the second guide rod is provided with a contact head. The contact head prevents the guide rod from directly contacting the contact sensor, and avoids damage to the sensing end of the contact sensor due to excessive impact force.

[0008] Preferably, a limiting ring is sleeved on the outer wall of one end of the guide rod, and a spring is sleeved on the outer wall of the guide rod, with its two ends connected to the limiting ring and the slide block respectively. The spring moves within the slide block via the guide rod, thereby guiding the spring, while the elastic force of the spring acts on the guide rod through the limiting ring.

[0009] Preferably, the upper end of the cone plate is provided with a cone surface whose height gradually increases from right to left. When the cone surface with gradually increasing height from right to left presses the guide rod two, as the guide rod one moves laterally, it gradually applies a pressing force to the guide rod two, causing the guide rod two to gradually rise.

[0010] Preferably, a rotating bead that rotatably fits against the conical surface is rotatably installed inside the lower end of the second guide rod. When the conical surface presses against the second guide rod, the rotating bead adjusts its rotation, causing it to slide on the conical surface, thereby reducing the resistance of the upper conical surface of the conical plate.

[0011] Preferably, a controller is provided at one end of the vent pipe, the controller is electrically connected to a contact sensor, and an alarm is provided at the upper end of the controller. The controller receives signals from the pressure sensor and the contact sensor, and controls the operation of the alarm, hydraulic rod, and motor.

[0012] Preferably, a motor is installed on one side of the upper end of the conveying pipe, a valve seat is installed on the inner wall of the conveying pipe, and a valve core is rotatably installed inside the valve seat at the lower output end of the motor. The valve core is rotatably supported inside the valve seat, and the opening of the conveying pipe is adjusted by the motor driving the valve core to rotate inside the valve seat.

[0013] Preferably, sliders are provided on both sides of the upper end of the closing seat, and guide rails are provided on both inner walls of the vent pipe. The sliders are slidably mounted on the outer walls of the guide rails. The closing seat is guided longitudinally by the sliders sliding on the outer walls of the guide rails.

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

[0015] 1. This utility model transports high-temperature and high-pressure steam through a conveying pipe. During this process, a pressure sensor detects the pressure inside the conveying pipe to understand the internal pressure situation. At the same time, the conveying pipe is equipped with an elastic support block and a guide rod II. Under the linkage of the cone plate, the extrusion force is applied to the cone plate through the support block, and the extrusion guide rod II is raised. It contacts the contact sensor through the contact head, which can also send an alarm signal, thereby controlling the connection between the vent pipe and the conveying pipe to achieve the depressurization of the high-temperature steam. This avoids the slow emergency response and high safety risks of manual valve closing by the staff. Attached Figure Description

[0022] 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.

[0023] like Figures 1-5 As shown, the present invention proposes a high-pressure steam overpressure early warning and high-stability gas supply device, which includes a conveying pipe 3, a motor 4, an vent pipe 7, a force-bearing block 14 and a guide rod 21. The upper end of the conveying pipe 3 is connected to the vent pipe 7, and a hydraulic rod 11 is installed inside the vent pipe 7. A closing seat 8 is installed at the lower end of the hydraulic rod 11, and a pressure sensor 1 is installed inside one end of the conveying pipe 3.

[0024] A controller 5 is installed at one end of the vent pipe 7, and an alarm 6 is installed at the upper end of the controller 5;

[0025] A motor 4 is installed on one side of the upper end of the conveying pipe 3, a valve seat 10 is installed on the inner wall of the conveying pipe 3, and a valve core 9 is rotatably installed inside the valve seat 10 at the lower output end of the motor 4.

[0026] Based on the implementation steps of Example 1: The conveying pipe 3 transports high-temperature, high-pressure steam. A pressure sensor 1 is installed on the conveying pipe 3 and connected to the controller 5. The pressure sensor 1 monitors the pressure inside the conveying pipe 3 and transmits the signal to the controller 5. The controller 5 needs to set a suitable alarm threshold. When the pressure sensor 1 detects that the internal pressure exceeds this threshold, the controller 5 triggers the corresponding alarm program. Once the controller 5 receives a signal from the pressure sensor 1 indicating that the pressure exceeds the preset threshold, the controller 5 activates the alarm 6 to notify the operator of an abnormal pressure situation. If the pressure exceeds the allowable range and is in a dangerous state, the controller 5 can control the hydraulic rod 11 to descend, causing the closing seat 8 to descend, connecting the vent pipe 7 to the conveying pipe 3, controlling the motor 4 to operate, and driving the valve core 9 to rotate to adjust the flow rate and provide pressure relief protection. This avoids the need for personnel to manually close the valve. During this process, the high pressure inside the conveying pipe 3 can cause significant damage to the equipment, potentially leading to serious equipment and personal injury. Automated pressure relief reduces equipment wear and eliminates the need for manual operation, making it safer.

[0027] like Figures 1-5As shown, compared with Embodiment 1, the high-pressure steam overpressure early warning and high-stability gas supply device proposed in this utility model further includes: a slide block 18 is provided on the inner wall of the lower end of the conveying pipe 3, a guide rod 17 is slidably installed inside the slide block 18, a force-bearing block 14 and a cone plate 19 are respectively provided at both ends of the guide rod 17, a sliding sleeve 24 is embedded inside the upper end of the conveying pipe 3, a guide rod 21 is slidably installed inside the sliding sleeve 24, a limit ring 22 is sleeved on the outer wall of the guide rod 21, a spring 23 connected to the inner wall of the upper end of the limit ring 22 is provided on the upper end of the limit ring 22, and a contact sensor 2 corresponding to the guide rod 21 is provided on the upper end of the conveying pipe 3;

[0028] A contact head 25 is provided at the upper end of the guide rod 21;

[0029] A limit ring 15 is sleeved on the outer wall of one end of the guide rod 17, and a spring 16 is sleeved on the outer wall of the guide rod 17, with its two ends connected to the limit ring 15 and the slide block 18 respectively.

[0030] The upper end of the cone plate 19 is provided with a cone surface whose height gradually increases from right to left;

[0031] The lower end of the guide rod 21 is rotatably fitted with a rotating ball 20 that fits against the conical surface;

[0032] Controller 5 is electrically connected to contact sensor 2;

[0033] Slider 12 is provided on both sides of the upper end of the closing seat 8, and guide rails 13 are provided on both sides of the inner wall of the vent pipe 7. The slider 12 is slidably installed on the outer wall of the guide rail 13.

[0034] In this embodiment, the internal mechanical structure of the conveying pipe 3 includes a compensation design for the pressure sensor 1. When the pressure sensor 1 is damaged, an alarm can also be triggered by the contact sensor 2, ensuring the stable operation of the system under high temperature and high pressure conditions. Even if either the pressure sensor 1 or the contact sensor 2 fails, the high pressure inside the conveying pipe 3 can be effectively alarmed, effectively reducing the probability of accidents. Once the pressure sensor 1 or the contact sensor 2 detects an abnormal signal, the controller 5 can react quickly by adjusting the opening of the valve core 9 through the motor 4 and operating the hydraulically driven closing seat 8 to quickly release the pressure of the high temperature and high pressure steam in the conveying pipe 3, thus avoiding equipment damage or safety accidents.

[0035] The above specific embodiments are merely several preferred embodiments of this utility model.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

No reference numerals in the claims should be construed as limiting the scope of the claims.
