Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline transportation technology, and specifically relates to a pipeline pressure tapping pipe structure with pressurized unblocking function. Background Technology
[0002] Due to the long transport distances and high system pressures of slurry pipelines in salt chemical enterprises, pressure tapping pipes are prone to salt buildup and blockage, leading to frequent malfunctions of pressure monitoring instruments (pressure transmitters or local pressure gauges) used in the slurry pipelines at the docks. To address this, manual unblocking / dredging of the pressure tapping pipes is required periodically. However, since the pressure tapping pipes of the pressure monitoring instruments used in this system have a conventional structure, manual unblocking / dredging can only be performed when the pipeline is depressurized. This situation passively reduces the stable operation rate of the pipeline transport system, compromises the long-term accuracy and stability of pressure measuring instruments, and increases the daily workload of maintenance personnel. To address these issues, a special research project is proposed to design a pipeline pressure tapping pipe structure with pressurized unblocking capabilities suitable for the salt chemical industry. This structure will enable unblocking of the internal pressure tapping pipes while ensuring the normal operation of equipment and pipelines, reducing the workload of personnel and improving the stable operation rate of pressure monitoring instruments and the pipeline transport system.

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.
[0022] This utility model provides a pipeline pressure tapping pipe structure with pressurized unblocking function, thereby improving the dredging efficiency.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] refer to Figures 1 to 2 A pipeline pressure tapping pipe structure with pressurized unblocking function includes a pressure-bearing flexible connector for connecting to a pipeline and an electric force-applying clamp assembly for applying pressure to the pressure-bearing flexible connector. The electric force-applying clamp assembly includes a clamp body disposed on the outer wall of the pressure-bearing flexible connector, two connecting rods connected to the clamp body, an internally threaded sliding body disposed on the connecting rods and having a hollow slide rail, a drive motor, a bidirectional lead screw disposed at the output end of the drive motor, and a torque guide rod disposed in the hollow slide rail. The internally threaded sliding body is respectively connected to two parts of the bidirectional lead screw with opposite threads. The drive motor is used to drive the bidirectional lead screw to rotate forward or in reverse. This utility model, through the electric force-applying clamp assembly and other structures, can complete the unblocking and dredging operation inside the pressure tapping pipe of the pressure monitoring sensor under pressurized pipeline conditions without investing too much work.
[0025] refer to Figures 1 to 2 The drive motor is a servo motor, and a speed reducer is provided at the servo motor.
[0026] Reference image Figure 2 The clamp body includes a first circular arc clamp and a second circular arc clamp that are hinged to each other, and the first circular arc clamp and the second circular arc clamp are respectively connected to the connecting rod.
[0027] Reference image Figure 2 The connecting rod includes a slanted segment and a straight segment, the straight segment being perpendicular to the bidirectional threaded screw, and the sliding body of the internal threaded sleeve being disposed on the straight segment.
[0028] refer to Figures 1 to 2 It also includes a fixing device, which includes an upper connecting flange disposed on the top of the pressure-bearing flexible connector and a lower connecting flange disposed on the bottom of the pressure-bearing flexible connector.
[0029] refer to Figures 1 to 2 It also includes a fixed connecting rod disposed between the upper connecting flange and the lower connecting flange.
[0030] refer to Figures 1 to 2 At least two fixed connecting rods are provided, and they are evenly spaced along the circumference of the upper connecting flange.
[0031] refer to Figures 1 to 2 The oblique line segment is slidably connected to one of the fixed connecting rods.
[0032] refer to Figure 2 Both the upper and lower connecting flanges are equipped with bolt holes.
[0033] Furthermore, the bolt holes are evenly spaced along the circumference of the upper or lower connecting flange.
[0034] The embodiments of this utility model are as follows:
[0035] The servo motor rotates in the forward direction. During this rotation, the sliding body of the internal threaded sleeve fitted with the bidirectional threaded screw moves synchronously towards the center of the bidirectional threaded screw. During this movement, the torque guide rod moves relative to the hollow slide rail. Since the torque guide rod can only move axially along the bidirectional threaded screw, the clamping body on the hollow slide rail side undergoes an inward angular displacement along the clamping body's central axis, thereby driving the clamping body structure on the other side to compress inward. During this compression process, the clamping body comes into contact with the pressure-bearing flexible connector, causing the pressure-bearing flexible connector to deform. During the deformation of the pressure-bearing flexible connector, it breaks down the internal salt deposits / blockages, thus achieving a clearing / unblocking effect.
[0036] Once the servo motor has rotated to its forward position, the clamping structure is pressed into place, and the pressure-bearing flexible connector deforms into place.
[0037] After clearing the blockage, the device is reset:
[0038] The servo motor rotates in the opposite direction. During this rotation, the sliding body of the internal threaded sleeve fitted with the bidirectional threaded screw moves synchronously to both ends of the bidirectional threaded screw. During this movement, the torque guide rod moves relative to the hollow slide rail. Since the torque guide rod can only move axially along the bidirectional threaded screw, the clamping body on the hollow slide rail side undergoes an outward angular displacement along the clamping body's central axis, thereby causing the clamping body structure on the other side to open outward. During this opening process, the clamping body and the pressure-bearing flexible connector tend to move away from each other. The pressure-bearing flexible connector, under internal pressure, undergoes a reset deformation. During the reset deformation of the pressure-bearing flexible connector, it further breaks down the internal salt deposits / blockages, thus achieving a second clearing / unblocking effect.
[0039] Once the servo motor has rotated in the reverse direction to its final position, the entire device resets.
[0040] At the same time, due to the inherent characteristics of the pressure-bearing flexible connector, online unblocking / dredging can be achieved during pressurized processes.
[0041] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
[0042] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the utility model.
