Description

Technical Field

[0001] This utility model relates to the field of pressure detection equipment technology, and in particular to a pressure detection device for industrial gas filling. Background Technology

[0002] In industrial production, the filling of industrial gases is crucial, and pressure control during the filling process is a key factor in ensuring filling safety and quality. Excessive pressure can lead to serious safety accidents such as gas cylinder explosions; insufficient pressure will fail to meet production needs and affect subsequent use. Therefore, real-time monitoring and effective control of pressure are necessary during the industrial gas filling process.

[0003] Most existing industrial gas filling pressure detection devices can only detect and display pressure. When the pressure is abnormal, manual intervention is often required to shut down the filling pipeline. The response speed is slow and there are significant safety hazards. Therefore, we propose an industrial gas filling pressure detection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pressure detection device for industrial gas filling. It can detect the pressure in real time through a pressure gauge, automatically shut off the branch pipe and issue a warning light when there is an abnormality, and has good sealing performance, which greatly improves the safety and reliability of filling operations.

[0006] By adopting the above technical solution, the pressure can be detected in real time by a pressure gauge. In case of abnormality, the branch pipe will be automatically shut off and a warning light will be issued. The sealing performance is good, which greatly improves the safety and reliability of the filling operation.

[0007] A further feature of this invention is that a sealing seat is fixedly installed inside the branch pipe, a groove is provided on one side of the sealing seat, and two through holes communicating with the groove are provided on the other side of the sealing seat.

[0008] By adopting the above technical solution, a stable channel for gas flow is provided, and the groove design provides a spatial basis for the subsequent installation of the sealing structure, ensuring the rationality of the gas filling path.

[0009] A further feature of this invention is that two rotating shafts are rotatably mounted on the top and bottom inner walls of the groove, and a semi-circular sealing plate is fixedly sleeved on the rotating shaft, with the semi-circular sealing plate matching the corresponding through hole. A sealing groove is provided on the inner wall of the groove, and a sealing strip is installed in the sealing groove, with the semi-circular sealing plate matching the sealing strip.

[0010] By adopting the above technical solution, the semi-circular sealing plate can accurately control the opening and closing of the through hole, and when combined with the sealing strip, it can greatly improve the sealing effect and effectively prevent gas leakage.

[0011] A further feature of this invention is that the top of the rotating shaft extends into the housing, and a linkage mechanism is provided on the two rotating shafts. The linkage mechanism includes two rotating gears. The rotating shafts are fixedly mounted with rotating gears, and the two rotating gears mesh with each other. Both rotating gears are located inside the housing.

[0012] By adopting the above technical solution, the synchronous reverse rotation of the two rotating shafts is achieved, ensuring that the semi-circular sealing plates can work together, guaranteeing the simultaneous opening and closing of the through holes, and improving the coordination of the structural movements.

[0013] A further feature of this invention is that a motor is fixedly installed on one side of the housing, the output shaft of the motor extends into the housing and a drive shaft is fixedly installed thereon, and a drive mechanism is provided between the drive shaft and the corresponding rotating shaft. The drive mechanism includes a worm and a worm wheel. The worm is fixedly installed on the drive shaft, the worm wheel is fixedly installed on the corresponding rotating shaft, and the worm meshes with the corresponding worm wheel.

[0014] By adopting the above technical solution and utilizing the transmission characteristics of worm gears, stable power transmission and speed reduction with torque increase are achieved, ensuring the accuracy and stability of the rotating shaft.

[0015] A further feature of this invention is that the motor is electrically connected to the controller, and the top of the branch pipe has two rotating holes, with the rotating shaft rotatably and sealingly connected to the corresponding rotating holes.

[0016] By adopting the above technical solution, the controller can automatically control the motor's operation, realizing intelligent start-up and closing. At the same time, the rotating sealing connection prevents gas leakage from the connection between the rotating shaft and the branch pipe, ensuring the overall sealing of the device.

[0017] The beneficial effects of this utility model are:

[0018] (1) By setting a pressure gauge, the pressure during the industrial gas filling process can be detected in real time. When the pressure is abnormal, the pressure gauge will transmit the signal to the controller, and the controller will light up the warning light to remind the staff to deal with it in time, which improves the safety of the operation.

[0019] (2) At the same time, the controller will start the motor after receiving the abnormal signal. The motor drives the rotating shaft to rotate through the drive mechanism. Under the action of the linkage mechanism, the two rotating shafts rotate synchronously in opposite directions, so that the semi-circular sealing plate rotates and closes the through hole, thereby realizing the closure of the branch pipe. This can quickly cut off the gas filling and avoid more serious consequences caused by abnormal pressure.

[0020] (3) The sealing groove and sealing strip on the sealing seat cooperate with the semi-circular sealing plate to improve the sealing performance of the semi-circular sealing plate when the through hole is closed, prevent gas leakage, and further ensure the safety and reliability of the device.

[0033] Specifically, two rotating shafts 401 are rotatably installed on the top and bottom inner walls of the groove 302. A semi-circular sealing plate 402 is fixedly sleeved on the rotating shaft 401, and the semi-circular sealing plate 402 is adapted to the corresponding through hole 303.

[0034] Specifically, a sealing groove is provided on the inner wall of the groove 302, a sealing strip is installed in the sealing groove, and the semi-circular sealing plate 402 is adapted to the sealing strip.

[0035] Specifically, the top of the rotating shaft 401 extends into the housing 501, and a linkage mechanism is provided on the two rotating shafts 401. The linkage mechanism includes two rotating gears 403. The rotating gears 403 are fixedly installed on the rotating shaft 401, and the two rotating gears 403 mesh with each other. Both rotating gears 403 are located inside the housing 501.

[0036] Specifically, a motor 505 is fixedly installed on one side of the housing 501. The output shaft of the motor 505 extends into the housing 501 and a drive shaft 503 is fixedly installed thereon. A drive mechanism is provided between the drive shaft 503 and the corresponding rotating shaft 401.

[0037] Specifically, the drive mechanism includes a worm 504 and a worm wheel 502. The worm 504 is fixedly mounted on the drive shaft 503, and the worm wheel 502 is fixedly mounted on the corresponding rotating shaft 401. The worm 504 meshes with the corresponding worm wheel 502.

[0039] Specifically, the top of the branch pipe 102 has two rotating holes, and the rotating shaft 401 is rotatably and sealingly connected to the corresponding rotating holes.

[0040] Working principle: When the pressure detection device for industrial gas filling is working, the industrial gas flows from the main filling pipe 101 into the branch pipe 102, then passes through the connecting sleeve 103 and the connecting pipe 104 in sequence, and finally fills the gas cylinder through the filling head 105.

[0041] During the filling process, the pressure gauge 201 on the top of the connecting sleeve 103 detects the filling pressure in real time and continuously transmits the detected pressure signal to the controller 202. When the pressure is within the normal range, the two semi-circular sealing plates 402 are in the open state, and the gas can pass smoothly through the two through holes 303 on the sealing seat 301 to ensure that the filling operation is carried out normally.

[0042] When pressure gauge 201 detects an abnormally high pressure, it transmits the abnormal signal to controller 202. Upon receiving the signal, controller 202 illuminates its warning light 203 to visually alert staff to the pressure abnormality. Simultaneously, controller 202 activates motor 505 on one side of housing 501. The output shaft of motor 505 drives drive shaft 503 to rotate, causing worm gear 504 on drive shaft 503 to rotate accordingly. Since worm gear 504 meshes with corresponding worm wheel 502, worm wheel 502 will... The corresponding rotating shaft 401 is driven to rotate. Under the action of the linkage mechanism, the rotating gears 403 on the two rotating shafts 401 mesh with each other, so that the two rotating shafts 401 rotate synchronously in opposite directions, thereby driving the two semi-circular sealing plates 402 to rotate. As the semi-circular sealing plates 402 rotate, they gradually come into close contact with the sealing strip in the groove 302 of the sealing seat 301, and close the corresponding through hole 303, thereby blocking the gas flow in the branch pipe 102, realizing the closure of the branch pipe 102, and avoiding the safety risks caused by continuing to fill under abnormal pressure.
