Description

Technical Field

[0001] This utility model relates to the technical field of pipeline water hammer eliminators, and in particular to a pipeline water hammer eliminator for liquid feeding. Background Technology

[0002] A water hammer eliminator is a device used to eliminate water hammer and surge phenomena in fluid transmission systems. Inside the eliminator is a sealed gas chamber with a piston at the bottom. When a shock wave enters the eliminator, the water hammer wave acts on the piston, causing it to move towards the gas chamber. The piston's stroke depends on the gas pressure within the chamber and the size of the water hammer wave. Under the combined action of a certain pressure of gas and irregular water hammer, the piston moves up and down, forming a dynamic balance. This effectively eliminates irregular water hammer wave oscillations. Water hammer eliminators are also used to assist in the feeding and transport of liquid feed.

[0003] In the prior art, according to announcement number CN220770491U, a water hammer eliminator for irrigation pipelines is disclosed, including a water hammer eliminator body. The water hammer eliminator body is a variable diameter structure composed of a 219mm diameter cavity and a 168mm diameter cavity. The 219mm diameter cavity is provided with a cavity elastic frame inside, and a cavity baffle is provided at the junction of the 219mm diameter cavity and the 168mm diameter cavity. The top of the 168mm diameter cavity is provided with a 2.5-inch welded pipe clamp, and an exhaust valve is connected to the top of the 2.5-inch welded pipe clamp. This water hammer eliminator for irrigation pipelines can protect components such as water pumps and check valves, improve the service life of water pumps, and reduce the failure rate of sprinkler irrigation machines.

[0004] However, while existing pipeline water hammer eliminators can effectively transport liquid feed, they are not very effective at depressurizing and transporting liquid feed within the pipeline. Furthermore, they are ineffective at securing and fixing the pipeline during transport, and the horizontal spacing of the clamping blocks is not highly adjustable. This can easily reduce the pipeline's impact resistance and buffering effect when subjected to impact forces, thus affecting the stability of the pipeline's continuous transport of liquid feed. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline-type water hammer eliminator for liquid feeding, which can solve the problems mentioned in the background art, such as poor auxiliary clamping and fixing effect of the pipeline when liquid feed is transported through the pipeline, low adjustability of the horizontal spacing of the clamping blocks, and easy reduction of the pipeline's impact resistance and buffering effect when impact forces occur in the pipeline.

[0007] By adopting the above technical solution, in order to improve the buffering effect against water hammer in the pipeline during the transportation of liquid feed, the pressure relief hole is set to allow the liquid in the delivery pipe to be depressurized. The liquid in the delivery pipe is sealed and transported through the connection of the sealing pipe to prevent excessive pressure in the liquid in the delivery pipe from causing pipeline damage. At the same time, the buffer chamber is set to buffer the impact force. Rotating the knob causes the threaded rod to rotate, which drives the positioning block to slide along the inner wall of the slide groove, so that the buffer pad fits the pipeline and reduces the vibration of the pipeline, thus reducing the impact on the stability of the pipeline during long-term use of liquid feed transportation.

[0008] A further feature of this invention is that the outer contours of both the positioning block and the buffer pad are arc-shaped, and the overall material of the buffer pad is soft silicone.

[0012] A further feature of this invention is that a sliding groove is provided at the connection between the outer wall of the sliding box and the positioning block, and the sliding groove and the positioning block are configured in a one-to-one correspondence.

[0013] By adopting the above technical solution, the effect of limiting the sliding of the positioning block is achieved.

[0014] A further feature of this invention is that the surface of the infusion tube is provided with pressure relief holes distributed in a grid pattern, and a buffer cavity is provided at the connection between the protective tube and the sealing tube.

[0017] By adopting the above technical solution, the rotating rod can be easily rotated.

[0018] A further feature of this invention is that one end of the rotating rod is rotatably connected to a rotating rod that is rotatably connected to the outer wall of the sliding box.

[0019] By adopting the above technical solution, the effect of relative sliding of the sliding box in its usage position can be achieved.

[0020] A further feature of this invention is that the rotating rod is provided in two sets, and the positions of the two sets of rotating rods are equidistant from the rotation center of the rotating rod, and the rotating rods and the sliding box are arranged in a one-to-one correspondence.

[0021] By adopting the above technical solution, the horizontal spacing of the positioning blocks can be conveniently adjusted.

[0022] A further feature of this invention is that a fixing groove is provided at the connection between the outer wall of the support base and the sliding box.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, by setting pressure relief holes and positioning blocks, improves the buffering effect against water hammer in the pipeline during the transportation of liquid feed. The pressure relief holes allow for pressure relief of the liquid in the delivery pipe, and the sealing pipe connection ensures a sealed delivery of the liquid, preventing excessive pressure in the delivery pipe and potential pipeline damage. Simultaneously, the buffer chamber buffers the impact force, and rotating the knob causes the threaded rod to rotate, which in turn drives the positioning block to slide along the inner wall of the groove, making the buffer pad fit against the pipeline and reducing pipeline shaking, thus reducing the impact on the stability of the pipeline during long-term transportation of liquid feed.

[0028] 2. By setting a rotating rod, this utility model can turn on the servo motor and drive the rotating rod to rotate when the horizontal spacing of the sliding box needs to be adjusted. The rotation of the rotating rod causes the sliding box to slide relative to the inner wall of the fixed groove, thereby achieving the effect of convenient adjustment of the horizontal spacing of the positioning block and improving the seismic stability of the pipeline in daily use.

[0036] Reference Figure 1-4A pipe-type water hammer eliminator for liquid feeding includes a support base 1, a sliding box 2 slidably connected to the outer wall of the support base 1, a positioning block 11 slidably connected to the outer wall of the sliding box 2, a buffer pad 12 fixedly connected to the inner side wall of the positioning block 11, a protective tube 7 attached to the inner side wall of the buffer pad 12, a sealing tube 6 disposed inside the protective tube 7, an infusion tube 4 attached to the inner wall of the sealing tube 6, a connecting flange 3 fixedly connected to the outer wall of the infusion tube 4, and a threaded rod 9 rotatably connected to the inner wall of the sliding box 2, which is threaded to the outer wall of the positioning block 11. A knob 10 is fixedly connected to one end of the threaded rod 9. When conveying liquid feed... To improve the buffering effect against water hammer in the pipeline, the pressure relief hole 5 is set to release the pressure of the liquid in the infusion pipe 4. The liquid in the infusion pipe 4 is sealed and transported through the connection of the sealing pipe 6 to prevent excessive pressure in the liquid in the infusion pipe 4 from causing pipeline damage. At the same time, the buffer chamber 8 is set to buffer the impact force. Rotating the knob 10 causes the threaded rod 9 to rotate, which drives the positioning block 11 to slide along the inner wall of the slide groove 13, so that the buffer pad 12 fits against the pipeline, reducing the vibration of the pipeline and affecting the stability of the pipeline during long-term use of liquid feed.

[0037] The outer contours of both the positioning block 11 and the buffer pad 12 are arc-shaped, and the overall material of the buffer pad 12 is soft silicone. This design, with the outer contours of both the positioning block 11 and the buffer pad 12 being arc-shaped, helps to improve the compatibility between the positioning block 11 and the pipe.

[0038] The threaded rod 9 is provided in two sets, and the two sets of threaded rod 9 rotate in opposite directions. This is beneficial to achieve the effect of driving the positioning block 11 to slide relative to each other by setting two sets of threaded rod 9 with opposite rotation directions.

[0039] Among them, the outer wall of the sliding box 2 is provided with a sliding groove 13 at the connection between it and the positioning block 11. The sliding groove 13 and the positioning block 11 are set in a one-to-one correspondence, which is conducive to achieving the effect of sliding and limiting the positioning block 11 through the setting of the sliding groove 13.

[0040] The infusion tube 4 has pressure relief holes 5 arranged in a grid pattern on its surface, and a buffer cavity 8 is provided at the connection between the protective tube 7 and the sealing tube 6. This facilitates the pressure relief of the liquid feed through the pressure relief holes 5 arranged in a grid pattern.

[0041] The bottom of the support base 1 is equipped with a servo motor 14, and the output end of the servo motor 14 is fixedly connected to a rotating rod 15 that is rotatably connected to the inner wall of the support base 1. This facilitates the rotation of the rotating rod 16 by means of the rotating rod 15.

[0042] One end of the rotating rod 15 is rotatably connected to a rotating rod 16 that is rotatably connected to the outer wall of the sliding box 2. This facilitates the sliding of the sliding box 2 by using the rotating rod 16.

[0043] The rotating rod 16 is provided in two sets. The positions of the two sets of rotating rods 16 are equidistant from the rotation center of the rotating rod 15. The rotating rods 16 and the sliding box 2 are set in a one-to-one correspondence. This arrangement is beneficial for achieving the effect of relative sliding of the sliding box 2.

[0044] The outer wall of the support base 1 is provided with a fixing groove 17 at the connection between it and the sliding box 2. This groove 17 helps to limit the sliding of the sliding box 2.

[0045] The length of the sealing tube 6 is matched with the length of the infusion tube 4, which helps to achieve a full-range sealing effect on the infusion tube 4.

[0046] In this invention, firstly, when conveying liquid feed, in order to improve the buffering effect against water hammer in the pipeline, the pressure relief hole 5 is set to allow the liquid in the delivery pipe 4 to be depressurized, and the liquid in the delivery pipe 4 is sealed and transported through the connection of the sealing pipe 6 to prevent the liquid from being under excessive pressure in the delivery pipe 4 and causing damage to the pipeline. At the same time, the buffer chamber 8 is set to buffer the impact force, and rotating the knob 10 causes the threaded rod 9 to rotate, which drives the positioning block 11 to slide along the inner wall of the slide groove 13, so that the buffer pad 12 fits against the pipeline, reducing the shaking of the pipeline and affecting the stability of the pipeline during long-term use of liquid feed.

[0047] Finally, when it is necessary to adjust the horizontal spacing of the sliding box 2, the servo motor 14 is turned on and connected to the rotating rod 15 to drive the rotating rod 16 to rotate. The rotation of the rotating rod 16 causes the sliding box 2 to slide relative to the inner wall of the fixed groove 17, thereby achieving the effect of convenient adjustment of the horizontal spacing of the positioning block 11 and improving the seismic stability of the pipeline during daily use.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
