Description

Technical Field

[0001] This utility model relates to the field of pumping device technology, specifically an emergency pumping pipeline structure. Background Technology

[0002] In applications such as industrial pipeline systems, chemical production environments, and power plant transmission pipelines, the internal pressure of pipelines may rise instantaneously to a dangerous threshold due to process fluctuations, media blockage, or equipment failure.

[0003] In existing technologies, pressure relief valves are often used for pipeline overpressure protection, but this approach has certain limitations:

[0004] The pressure relief valve has a delayed response, and existing emergency pumping devices mostly use independent power sources or complex control systems, which pose a risk of not being able to start quickly in the event of a sudden power outage or control system failure, thus reducing reliability in emergency situations. Utility Model Content

[0005] The purpose of this invention is to provide an emergency pumping pipeline structure to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An emergency pumping pipeline structure includes a pumping pipeline, wherein a pressure relief mechanism is fixedly connected to the periphery of the pumping pipeline.

[0008] The pressure relief mechanism includes a bypass pipe that is fixedly connected to the pumping pipeline. The end of the bypass pipe away from the pumping pipeline is a closed structure, and a sealed linear bearing is embedded in the center of the end of the bypass pipe away from the pumping pipeline.

[0009] A guiding mechanism is fixedly connected to the periphery of the bypass pipe near the pumping pipe.

[0010] A switch assembly for controlling the opening and closing of the inlet end of the conveying mechanism is slidably installed in the bypass pipe.

[0011] Furthermore, the switch assembly includes a plunger and a limiting groove. The plunger is slidably installed in the bypass pipe, and the end of the plunger near the pumping pipe is a curved surface that cooperates with the pumping pipe.

[0012] The plunger is fixedly connected to a guide rod coaxial with the plunger at one end away from the pumping pipe. The guide rod at one end away from the plunger slides through the sealed linear bearing to the outside of the bypass pipe at one end away from the pumping pipe. A baffle is fixedly installed at one end of the guide rod outside the bypass pipe. An elastic force-applying component is provided on the periphery of the guide rod near the baffle and between the guide rod and the end of the bypass pipe away from the pumping pipe.

[0013] The inner wall of the bypass pipe has two symmetrically arranged limiting grooves, and two limiting rods are fixedly connected to the outer periphery. The ends of the two limiting rods away from the guide rod are respectively slidably locked in the two limiting grooves.

[0014] Under the action of the elastic force application component, the end of the plunger near the pumping pipe is aligned with the inner wall of the pumping pipe. At this time, the plunger closes the guiding mechanism, and the end of the limiting rod away from the guide rod is in the limiting groove near the end of the pumping pipe. The end of the limiting rod away from the guide rod and the end of the limiting groove near the pumping pipe are in compressive contact.

[0015] Furthermore, the elastic force application component includes a thread disposed on the periphery of the guide rod and an adjustment component installed on the periphery of the guide rod through the thread. The adjustment component is fixedly connected to the end of the bypass pipe away from the pumping pipe, and a spring sleeved on the periphery of the guide rod is provided. The spring is in a stretched state.

[0016] Furthermore, the adjustment assembly includes a threaded ring mounted on the periphery of the guide rod via the threaded through-thread, and a plurality of handles are fixedly connected to the periphery of the threaded ring;

[0017] The threaded ring is rotatably connected to a mounting plate sleeved around the guide rod on the side near the bypass pipe, and the spring is fixedly connected between the side of the mounting plate away from the threaded ring and the end of the bypass pipe away from the pumping pipeline.

[0018] Furthermore, the guiding mechanism includes a pipe joint one and a pipe joint two that are fixedly connected to the periphery of the bypass pipe, with the pipe joint one located between the pipe joint two and the pumping pipe.

[0019] The ends of the first and second pipe joints away from the bypass pipe are fixedly connected to conduits, and the ends of the conduits away from the second pipe joint extend to the upstream of the buffer tank or the pumping system.

[0020] The beneficial effects of this utility model are:

[0021] 1. In this utility model, through the coordinated arrangement of bypass pipe, switch assembly, spring, adjustment assembly and guide assembly, pressure relief can be automatically performed when the pressure in the pumping pipeline exceeds the threshold. No electrical control signal is required, the response speed is fast, and the problem of pressure relief valve in the pumping system being unable to start quickly in the event of a sudden power outage or control system failure is solved, thereby improving the stability of the pumping process.

[0022] 2. In the adjustment component of this utility model, rotating the threaded ring with the handle can drive the mounting plate to move on the periphery of the guide rod, thereby changing the initial tension of the spring. Different initial tensions of the spring correspond to different pipe pressures, thus making this utility model applicable to pumping pipelines with different pipe pressure requirements within a certain range, providing the utility model with practicality.

[0030] 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.

[0031] Example 1: Please refer to Figures 1-4 In this embodiment of the utility model, an emergency pumping pipeline structure includes a pumping pipeline 1, and a pressure relief mechanism is fixedly connected to the periphery of the pumping pipeline 1.

[0032] The pressure relief mechanism includes a bypass pipe 2 that is fixedly connected to the pumping pipeline 1. The end of the bypass pipe 2 away from the pumping pipeline 1 is a closed structure, and a sealed linear bearing 14 is embedded in the center of the end of the bypass pipe 2 away from the pumping pipeline 1.

[0033] A guiding mechanism is fixedly connected to the periphery of the bypass pipe 2 near the pumping pipe 1;

[0034] A switch assembly for controlling the opening and closing of the inlet end of the guide mechanism is slidably installed in the bypass pipe 2.

[0035] The switch assembly includes a plunger 13 and a limiting slide groove 16. The plunger 13 is slidably installed in the bypass pipe 2. The end of the plunger 13 near the pumping pipe 1 is a curved surface that cooperates with the pumping pipe 1.

[0036] A guide rod 6, coaxial with the plunger 13, is fixedly connected to the end of the plunger 13 away from the pumping pipe 1. The end of the guide rod 6 away from the plunger 13 slides through the end of the bypass pipe 2 away from the pumping pipe 1 via a sealed linear bearing 14 to the outside of the bypass pipe 2. A baffle 7 is fixedly installed at the end of the guide rod 6 located outside the bypass pipe 2. An elastic force-applying component is provided on the periphery of the guide rod 6 near the baffle 7 and between the end of the bypass pipe 2 away from the pumping pipe 1.

[0037] Two symmetrically arranged limiting grooves 16 are opened on the inner wall of the bypass pipe 2. Two limiting rods 15 are fixedly connected to the outer periphery of the guide rod 6. The ends of the two limiting rods 15 away from the guide rod 6 are respectively slidably locked in the two limiting grooves 16.

[0038] Under the action of the elastic force application component, the end of the plunger 13 near the pumping pipe 1 is aligned with the inner wall of the pumping pipe 1. At this time, the plunger 13 closes the guiding mechanism. Meanwhile, the end of the limiting rod 15 away from the guide rod 6 is in the limiting groove 16 near the end of the pumping pipe 1, and the end of the limiting rod 15 away from the guide rod 6 and the end of the limiting groove 16 near the pumping pipe 1 are in extrusion contact.

[0039] The elastic force application component includes a thread 8 set on the periphery of the guide rod 6 and an adjustment component installed on the periphery of the guide rod 6 through the thread 8. A spring 9 sleeved on the periphery of the guide rod 6 is fixedly connected between the adjustment component and the end of the bypass pipe 2 away from the pumping pipe 1. The spring 9 is in a stretched state.

[0040] The guiding mechanism includes a pipe joint 3 and a pipe joint 4 that are fixedly connected to the outside of the bypass pipe 2. The pipe joint 3 is located between the pipe joint 4 and the pumping pipe 1.

[0041] Pipe joint 3 and pipe joint 4 are fixedly connected to a conduit 5 at the end away from the bypass pipe 2. The end of the conduit 5 away from pipe joint 4 extends to the upstream of the buffer tank or pumping system.

[0042] When using this utility model:

[0043] During the overpressure process in pumping pipeline 1, plunger 13 slides away from pumping pipeline 1 in bypass pipe 2 according to the pressure. During the sliding of plunger 13, pipe joint 3 in the conveying mechanism gradually opens first, and the material in pumping pipeline 1 will enter the conduit 5 through bypass pipe 2 and pipe joint 3 and be conveyed to the buffer tank or upstream of the pumping system, thereby completing the depressurization purpose. During the movement of plunger 13, the degree of tension of spring 9 also increases. When the pressure in pumping pipeline 1 returns to normal, spring 9 drives guide rod 6 to reset, thereby driving plunger 13 to reset, so that the end of plunger 13 away from guide rod 6 is re-aligned with the inner wall of pumping pipeline 1, and the outer periphery of plunger 13 re-closes pipe joint 3.

[0044] Therefore, through the coordinated arrangement of the bypass pipe 2, the switch assembly, the spring 9, the adjustment assembly, and the guide assembly, this utility model can automatically release pressure when the pressure in the pumping pipeline 1 exceeds the threshold, without the need for an electrical control signal. It has a fast response speed, solves the problem that the pressure relief valve in the pumping system cannot start quickly when there is a sudden power outage or control system failure, and improves the stability of the pumping process.

[0045] In the guiding mechanism, when the pipe pressure is high, pressure can be released simultaneously through pipe joint 3 and pipe joint 4, thereby increasing the pressure release speed. That is, the setting of pipe joint 3 and pipe joint 4 realizes staged pressure release and improves the stability of pipe pressure.

[0046] Example 2: Please refer to Figures 1-3 Based on embodiment 1, the adjustment assembly includes a threaded ring 12 that is threaded through the guide rod 6 and installed on the periphery of the guide rod 6 by the thread 8. Multiple handles 11 are fixedly connected to the periphery of the threaded ring 12.

[0047] A mounting plate 10, which is sleeved around the guide rod 6, is rotatably connected to the side of the threaded ring 12 near the bypass pipe 2. A spring 9 is fixedly connected between the side of the mounting plate 10 away from the threaded ring 12 and the end of the bypass pipe 2 away from the pumping pipe 1.

[0048] In the adjustment assembly, rotating the threaded ring 12 by the handle 11 can drive the mounting plate 10 to move on the periphery of the guide rod 6, thereby changing the initial tension of the spring 9. Different initial tensions of the spring 9 correspond to different pipe pressures, thus making this utility model applicable to pumping pipelines 1 with different pipe pressure requirements within a certain range, providing the utility model with practicality.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
