Description

Technical Field

[0001] This utility model belongs to the field of industrial pipeline technology, specifically a purging and guiding device. Background Technology

[0002] Pipeline purging is an essential part of pipeline operations. Purging has two purposes. The first purpose is to blow out impurities generated during the handling, welding, and connection of the pipeline using high-pressure fluid to achieve the goal of cleaning the inside of the pipeline and then conduct pressure testing. The second purpose is to dry the water vapor generated during the pressure test after the test is completed to ensure cleanliness.

[0003] High-pressure gas is generally used during purging, but high-pressure mixed solutions may be used in special circumstances. Large industrial pipelines may also be purged using explosive shock waves.

[0004] During the purging process of some small pipelines, due to the complex pipeline layout and confined space, the high-pressure gas generated during purging carries particulate impurities from inside the pipeline and ejects them at high speed, impacting walls, workers, or already installed pipelines. Therefore, it is necessary to guide the airflow ejected from the end of the pipeline during purging to achieve the purpose of protection. Existing protective facilities simply use temporary structures made of boards to perform some airflow guidance operations, or require workers to stay away from the direction of the airflow during purging operations. These measures are not safe enough and are not convenient for on-site use and adjustment.

[0005] Based on this, a device was designed that is easy to connect to pipelines and allows for convenient adjustment of the airflow direction angle and inclination, thereby guiding the blown airflow and improving safe production. Utility Model Content

[0006] The purpose of this utility model is to provide a purging guide device in order to solve the above-mentioned problems.

[0007] The technical solution adopted by this utility model is as follows: a purging guide device includes a positioning ring, a guide ring is integrally provided on the side edge of the positioning ring, and a flow guiding component that can be adjusted according to needs is provided on the guide ring; a connecting component for clamping the pipeline is provided inside the positioning ring.

[0008] The flow guiding assembly includes: annular slide, connecting ear A, slider, sliding sleeve, square steel, adjustable telescopic rod, connecting ear B, bearing shaft, flow guiding groove, and traction cable;

[0009] A connecting lug A is welded to the side edge of the guide ring. An annular groove is embedded in the outer ring of the guide ring. A slider is slidably connected inside the annular groove.

[0010] A flow guide groove is rotatably connected to one side of the square steel via a bearing shaft. An adjustable telescopic rod is rotatably connected to the back of the flow guide groove. Connecting ears B are symmetrically arranged on both sides of the square steel. A traction cable is connected between the connecting ears B and the connecting ears A.

[0011] The connecting components include: positioning block, guide post, and lead screw;

[0012] The positioning ring has a positioning block inside, and the back of the positioning block is integrally provided with guide posts, and there are two guide posts. A lead screw is rotatably connected between the guide posts on the back of the positioning block.

[0013] The guide post and the lead screw both extend into a positioning ring, and the lead screw and the positioning ring are threaded together. The connecting components are in three groups, evenly distributed on the positioning ring, and the guide post surface is provided with scale lines.

[0026] 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.

[0027] In this utility model:

[0028] Reference Figure 1-4 A purging guide device includes a positioning ring 1, a guide ring 2 integrally provided on the side edge of the positioning ring 1, and a flow guiding component that can be adjusted according to needs on the guide ring 2; a connecting component for clamping the pipeline is provided inside the positioning ring 1.

[0029] The flow guiding assembly includes: annular slide 201, connecting ear A202, slider 3, sliding sleeve 301, square steel 4, adjustable telescopic rod 401, connecting ear B402, bearing shaft 403, flow guiding groove 5, and traction cable 7;

[0030] The guide ring 2 has several connecting ears A202 welded along its side. The outer ring of the guide ring 2 has an annular groove 201 embedded in it. A slider 3 is slidably connected inside the annular groove 201. A sliding sleeve 301 is connected above the slider 3. A square steel 4 is slidably connected inside the sliding sleeve 301. Threaded holes are provided on both sides of the slider 3. By screwing bolts into the threaded holes on both sides of the slider 3, the slider 3 can be positioned to prevent it from sliding. This allows for angle adjustment of the guide channel 5, guiding the direction of the blowing airflow and improving flexibility. Threaded holes are provided above both the sliding sleeve 301 and the square steel 4. By locking the sliding sleeve 301 and the square steel 4 with bolts, the position of the square steel 4 can be fixed, thereby adjusting the guiding impact force.

[0031] A guide channel 5 is rotatably connected to one side of the square steel 4 via a bearing shaft 403. An adjustable telescopic rod 401 is rotatably connected to the back of the guide channel 5. The inner and outer rods of the adjustable telescopic rod 401 are connected by bolts for positioning. The inner and outer rods of the adjustable telescopic rod 401 are rotatably connected to the guide channel 5 and the square steel 4, respectively. This setting allows for adjustment of the tilt of the guide channel 5 by adjusting the length of the adjustable telescopic rod 401, thereby adjusting the direction of the blowing airflow and improving practicality. Connecting ears B402 are symmetrically arranged on both sides of the square steel 4. A traction cable 7 is connected between the connecting ears B402 and the connecting ears A202. The traction cable 7 can indirectly connect the square steel 4 and the guide ring 2 to form a triangular structure, thereby improving the support strength of the square steel 4 when subjected to airflow impact. At the same time, the traction cable 7 is a flexible connection and can be tied to the connecting ears B402 and the connecting ears A202 according to the usage.

[0032] The connecting components include: positioning block 6, guide post 601, and lead screw 602;

[0033] The inner ring of the positioning ring 1 has a positioning block 6. Two guide posts 601 are integrally formed on the back of the positioning block 6. A lead screw 602 is rotatably connected between the guide posts 601 on the back of the positioning block 6. Both the guide posts 601 and the lead screw 602 extend out of the positioning ring 1, and the lead screw 602 is threadedly engaged with the positioning ring 1. By rotating the lead screw 602, the thread engagement, combined with the sliding guiding action of the guide posts 601, allows the positioning block 6 to move downwards, thereby clamping the pipe. Simultaneously, a rubber layer is attached to the surface of the positioning block 6 to increase friction. Three sets of connecting components are evenly distributed on the positioning ring 1. The guide posts 601 have scale lines on their surfaces. These three sets of connecting components ensure more even force distribution when clamping the pipe. Furthermore, the scale lines on the surface of the guide posts 601 help to monitor the position and height of the positioning block 6, ensuring consistency between the positioning block 6 and the pipe connection.

[0034] Furthermore, the guide channel 5 is U-shaped. The U-shape can concentrate the purging airflow, prevent the airflow from spreading, and prevent the impurities being purged from causing harm to the construction personnel.

[0035] Working principle: First, the positioning ring 1 is placed on the outside of the pipe. Simultaneously, by rotating the lead screw 602, the thread engagement, combined with the guiding action of the guide post 601, causes the positioning block 6 to move downwards, thus clamping the pipe. The surface of the positioning block 6 is coated with a rubber layer to increase friction. The scale lines on the surface of the guide post 601 help to check the position and height of the positioning block 6, ensuring consistency between the positioning block 6 and the pipe connection. Next, by rotating the slider 3, it moves within the annular groove 201, indirectly driving the guide groove 5 to move around the pipe, thereby determining the guide angle and improving the practicality of the device in confined spaces. After adjustment, bolts are screwed into the threaded holes on both sides of the slider 3 to achieve the purpose of positioning the slider 3 and preventing it from sliding. The sliding sleeve 301 and... Each square steel 4 has a corresponding threaded hole. The sliding sleeve 301 is locked to the square steel 4 with bolts, which can fix the position of the square steel 4 and adjust the flow impact force. The worker binds the connecting lug 7 between the connecting ear B402 and the connecting ear A202. The connecting lug 7 can indirectly connect the square steel 4 and the guide ring 2 to form a triangular structure, which improves the support strength of the square steel 4 when it is impacted by the airflow. Finally, by adjusting the length of the adjustable telescopic rod 401, the inclination of the flow channel 5 can be adjusted, thereby adjusting the direction of the blowing airflow and improving practicality. During blowing, the "U" shape can concentrate the blowing airflow more and prevent the airflow from spreading. At the same time, it can prevent the blowing impurities from causing injury to the construction personnel.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
