Description

Technical Field

[0001] This utility model relates to the technical field of chlorine and hydrogen production equipment, and particularly to a hydraulic sensing pipeline structure for a liquid chlorine low-pressure unit. Background Technology

[0002] The liquid chlorine low-pressure unit plays a crucial role in the production process of the chlorine plant, and its stable operation is of paramount importance. The oil pressure obtained through the oil pressure sensor pipeline is one of the key parameters reflecting the unit's operating status. Accurate monitoring of oil pressure is of great significance for ensuring the normal operation of the unit and preventing malfunctions.

[0003] Traditional hydraulic pressure sensing pipelines are usually straight pipes, which do not have a buffering effect. As a result, the hydraulic pressure pulses are directly transmitted to the hydraulic pressure sensor, causing fluctuations in the sensor data. When the hydraulic pressure fluctuations are too large, it will cause the equipment to stop and affect the production schedule.

[0004] Therefore, there is an urgent need for a pipeline that can buffer oil pressure pulses and reduce the number of equipment shutdowns caused by abnormal oil pressure. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a hydraulic pressure sensing pipeline structure for liquid chlorine low-pressure units that is not easily loosened or shifted, can suppress the interference of oil pressure fluctuations on the sensor, and reduce the number of trips caused by abnormal oil pressure.

[0007] Preferably, each end of the positioning post is provided with multiple extension plates, and the extension plates at both ends of the positioning post correspond one-to-one; a positioning pressure rod is provided between every two upper and lower extension plates.

[0008] Preferably, the surface of the extension plate is provided with a waist hole, the positioning pressure rod is provided in the waist hole, and the outer end face of the extension plate is provided with a fastening bolt, which abuts against the circumference of the positioning pressure rod after being tightened.

[0009] Preferably, when the fastening bolt abuts against the circumference of the positioning rod, the positioning rod comes into contact with the hydraulic pipeline.

[0010] Preferably, the hydraulic pipeline is further provided with an inner tube, and the surface of the inner tube is uniformly provided with a plurality of through holes, and the inner cavity of the hydraulic pipeline and the inner cavity of the inner tube are connected through the through holes.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please refer to Figure 1-6A hydraulic sensing pipeline structure for a liquid chlorine low-pressure unit includes a hydraulic pipeline 1 and a positioning column 2. The hydraulic pipeline 1 is in the shape of a spiral spring, and both ends of the hydraulic pipeline 1 are provided with connecting flanges 11. The entire structure is connected to other oil pipelines through the connecting flanges 11. The outer wall of the positioning column 2 is provided with a positioning groove 21 that is the same as the spiral trajectory of the hydraulic pipeline 1. The hydraulic pipeline 1 is coiled in the positioning groove 21 on the outer wall of the positioning column 2.

[0021] In other words, the dimensions and pitch of the positioning groove 21 are the same as those of the spring-shaped hydraulic pipe 1, so that the hydraulic pipe 1 is coiled in the positioning groove 21, preventing the hydraulic pipe 1 from loosening or shifting during use and affecting pressure stability.

[0022] Furthermore, because the hydraulic pipe 1 is in the shape of a spiral spring, it optimizes the stability of the hydraulic signal during use and suppresses the interference of hydraulic pressure fluctuations on the sensor; specifically:

[0023] When the unit is running, the meshing of the oil pump gears and the rotation of the bearings will generate periodic oil pressure pulses (similar to water flow impact). Since traditional straight pipes have no buffer structure, the pulses will be directly transmitted to the oil pressure sensor, causing fluctuations in the sensor data.

[0024] The spiral spring-shaped hydraulic pipe 1 can consume fluctuation energy due to multiple reflections from the pipe wall and continuous changes in the flow direction. This makes the hydraulic pulse smoother, so that the hydraulic pressure signal received by the sensor is closer to the real steady-state hydraulic pressure, avoiding shutdowns caused by hydraulic pressure fluctuations and ensuring stable production.

[0025] In this embodiment, multiple extension plates 22 are provided at both ends of the positioning post 2, and the extension plates 22 at both ends of the positioning post 2 correspond one-to-one; a positioning pressure rod 24 is provided between every two upper and lower extension plates 22.

[0026] Furthermore, the surface of the extension plate 22 is provided with a waist hole 23, the positioning pressure rod 24 is provided in the waist hole 23, and the outer end face of the extension plate 22 is provided with a fastening bolt 25, which abuts against the circumference of the positioning pressure rod 24 after being tightened.

[0027] In this embodiment, a baffle plate is also provided at the top of the positioning rod 24 to prevent it from sliding out of the waist hole 23. When in use, the positioning rod 24 is first placed into the waist hole 23, and then the bolt 25 is tightened so that the positioning bolt 25 extends inward and abuts against the circumference of the positioning rod 24.

[0028] When the fastening bolt 25 abuts against the circumference of the positioning rod 24, the positioning rod 24 comes into contact with the hydraulic pipeline 1. After contact, it can further limit the hydraulic pipeline 1 and ensure its stability in use.

[0029] Of course, when the fastening bolt 25 abuts against the circumference of the positioning rod 24, a gap can still be left between the positioning rod 24 and the hydraulic pipe 1. The gap setting can not only achieve further limiting, but also prevent the positioning rod 24 from squeezing the hydraulic pipe 1, ensuring the smooth flow of internal oil circuit.

[0030] As a preferred embodiment, the hydraulic pipeline 1 is further provided with an inner tube 12, and the surface of the inner tube 12 is uniformly provided with a plurality of through holes 13. The inner cavity of the hydraulic pipeline 1 and the inner cavity of the inner tube 12 are connected through the through holes 13. While ensuring the smooth flow of the internal oil circuit, the inner tube 12 and the through holes 13 can further consume the energy of oil circuit fluctuations, reduce oil pressure fluctuations, and make the oil pressure signal received by the sensor more stable, which can further reduce the number of trips.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
