Description

Technical Field

[0001] This utility model belongs to the field of pressure detection technology, specifically relating to a safe pressure measurement and explosion-proof device. Background Technology

[0002] Petroleum is a natural mixture containing gaseous, liquid, and solid hydrocarbon components. It is mainly collected and transported through oil and gas pipeline systems. These pipelines are generally equipped with pressure monitoring devices to monitor the pressure inside the pipeline in real time, so as to ensure the safety of the transportation process and prevent explosion accidents.

[0003] Patent CN203443730U discloses an oilfield safety pressure detection device. When used to measure the pressure of a pipeline, this device first prevents leakage of the measured medium (such as oil) during installation by closing a solenoid valve. When pressure measurement is required, the solenoid valve opens, allowing the measured medium to flow into a second pipeline. In this system, the measured medium pushes a piston, which then transmits pressure to a pressure gauge via the liquid medium, enabling operators to accurately read the pressure value within the pipeline. However, in actual operation, because the pressure tapping pipeline is directly connected to the measured pipeline, a strong impact force is generated when the measured medium rushes in at high speed. This impact force may damage the internal components of the pressure tapping device, thereby shortening its service life and reducing its reliability and convenience in practical applications. Utility Model Content

[0004] The purpose of this invention is to provide a pipeline safety pressure testing and explosion-proof device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline safety pressure testing and explosion-proof device, comprising a pipeline body, a relief valve installed on the pipeline body, a pressure gauge installed on the right side of the pipeline body via a medium pipeline, a mounting bracket provided on the left side of the pipeline body, multiple sliding grooves opened on the left side of the mounting bracket, sliding plates slidably connected to each of the sliding grooves by springs, buffer plates connected between the sliding plates, multiple buffer holes opened on the buffer plates, and a backflush assembly provided on the right side inside the pipeline body, the backflush assembly including an extension frame, a hinge block, a threaded assembly, a screw, and a fan.

[0006] Preferably, the extension frame extends inward from the inner wall of the main pipe body, the extension frame is connected to the hinge block, the screw is movably connected to the hinge block through the threaded assembly, and the fan is provided on the right side of the screw.

[0007] Preferably, the screw has a rotating seat on its left side.

[0008] Preferably, a gas collecting cylinder is fixedly installed inside the main body of the pipeline. The gas collecting cylinder has an air inlet on the left side and an air outlet on the right side. The rotating seat is located behind the air outlet.

[0009] Preferably, a sliding hole is provided in the middle of the buffer plate, and the air inlet extends to protrude from the left side of the sliding hole.

[0010] Preferably, the inner wall of the mounting bracket is provided with multiple balancing baffles.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By using a buffer plate with multiple buffer holes, the gas entering the main body of the pipeline is dispersed into multiple small airflows through the buffer holes on the buffer plate. The impact force of each airflow is less than that of the original high-pressure gas, thereby reducing the impact force and the possibility of damage to the internal components of the pipeline. A backflush component is also provided. When the gas blows towards the medium pipeline, it drives the fan to rotate and blow out a left-flowing airflow. That is, the fan airflow and the high-pressure gas present forces in two directions, which are called backflow forces. These forces interact with the original impact force of the "high-pressure gas". The interaction force between the two generates an interaction force. The force of the fan can offset part of the original impact force brought by the high-pressure gas, ultimately achieving the effect of mitigating the impact force. This further reduces the possibility of damage to the internal components of the pipeline caused by excessive impact force, ensures the normal service life of the device, and enhances its reliability and convenience in practical applications.

Detailed Implementation

[0018] 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.

[0019] Example 1

[0020] like Figures 1 to 5 The pipeline safety pressure testing and explosion-proof device shown includes a pipeline body 1, a relief valve 2 installed on the pipeline body 1, a pressure gauge 4 installed on the right side of the pipeline body 1 via a medium pipeline 3, a mounting bracket 5 on the left side of the pipeline body 1, multiple sliding grooves 6 on the left side of the mounting bracket 5, each sliding groove 6 being slidably connected to a slide plate 8 by a spring 7, buffer plates 9 connecting the slide plates 8, and multiple buffer holes 10 on the buffer plates 9, and a backflush assembly 11 on the right side inside the pipeline body 1, the backflush assembly 11 including an extension frame 111, a hinge block 112, a threaded assembly 113, a screw 114, and a fan 115; inside the pipeline body 1... The walls are all provided with extension frames 111 extending inward, and the extension frames 111 are connected by hinge blocks 112. The hinge blocks 112 are movably connected to screws 114 through threaded components 113. A fan 115 is provided on the right side of the screws 114. A rotating seat 12 is provided on the left side of the screws 114. An air collecting cylinder 13 is fixedly provided inside the main pipe body 1. An air inlet 14 is provided on the left side of the air collecting cylinder 13, and an air outlet 15 is provided on the right side of the air collecting cylinder 13. The rotating seat 12 is located behind the air outlet 15. A sliding hole 16 is opened in the middle of the buffer plate 9, and the air inlet 14 extends to protrude from the left side of the sliding hole 16. Multiple balance baffles 17 are provided on the inner wall of the mounting bracket 5.

[0021] This invention utilizes a buffer plate 9 with multiple buffer holes 10. This allows gas entering the main pipe 1 to be dispersed into multiple small streams of air as it passes through the buffer holes 10. The impact force of each stream is less than that of the original high-pressure gas, thus reducing the impact force and minimizing damage to internal pipe components. Furthermore, a backflush component 11 is included. When gas blows towards the medium pipe 3, it drives a fan 115 to rotate and blow out a leftward-flowing airflow. This airflow from the fan 115 creates a counterforce with the high-pressure gas, interacting with the original impact force. The force of the fan 115 can offset part of the original impact force from the high-pressure gas, ultimately reducing the impact force and further minimizing damage to internal pipe components caused by excessive impact. This ensures the normal service life of the device and enhances its reliability and convenience in practical applications.

[0022] Example 2

[0023] like Figures 1 to 5 The illustrated pipeline safety pressure testing and explosion-proof device includes a pipeline body 1 for connecting to the pipeline under test. The pipeline body 1 is also equipped with a relief valve 2, which can be used to intercept or release high-pressure gas in the pipeline under test, providing simple control over the gas and preventing direct overflow that could lead to safety accidents. When the pipeline body 1 is connected to the pipeline under test, the relief valve 2 is in a closed mode to prevent gas overflow during installation. When testing is required, the relief valve 2 opens the pipeline body 1, allowing the high-pressure gas in the pipeline under test to automatically flow to the right, and then further to the right through the pipeline body 1 for testing. Furthermore, a pressure gauge 4 is installed on the right side of the pipeline body 1 via a medium pipeline 3. The pressure gauge 4 is an auxiliary tool for detecting the pressure status of oil pipelines or related equipment. Regular testing and pressure measurement of the oil pipeline using the pressure gauge 4 can promptly detect and prevent production failures caused by abnormal pipeline and equipment pressure, improving production efficiency and safety.

[0024] It should be noted that the pressure test of an oil pipeline needs to simulate the pipeline's operating condition to a certain extent, i.e., when high-pressure gas rushes into the oil pipeline. Because the high-pressure gas will generate a large impact force after rushing into the pipeline body 1, if the pressure gauge 4 is placed too close to the vent, it will be damaged by the impact force, thus affecting the service life of the entire device. Therefore, a medium pipeline 3 is also connected between the pipeline body 1 and the pressure gauge 4. By setting a liquid medium in the medium pipeline 3, the distance between the gas and the pressure gauge 4 after the gas is released is extended, and the pressure value is indirectly read through the pressure received by the liquid medium, effectively reducing the impact force on the pressure gauge 4.

[0025] Furthermore, a mounting bracket 5 is provided on the left side of the main pipe body 1. The mounting bracket 5 is a ring-shaped mounting base and is set parallel to the main pipe body 1. A buffer plate 9 is slidably installed inside the mounting bracket 5 to buffer the impact force brought by the gas. Multiple sliding grooves 6 are opened on the left side of the mounting bracket 5. Slide plates 8 are connected to the sliding grooves 6 by springs 7. That is, the slide plates 8 will move left and right in the sliding grooves 6, thereby driving the buffer plates 9 connected between the slide plates 8 to move to the right.

[0026] It should be noted that the buffer plate 9 does not reduce the impact force of the high-pressure gas by the buffer plate 9 itself, but by the multiple buffer holes 10 on the buffer plate 9. The spring 7 connecting the buffer plate 9 and the mounting bracket 5, and the fact that the buffer plate 9 is made to be slidable, is only to prevent the buffer plate 9 from breaking when the impact force directly resists it. When the gas continues to flow into the main body of the pipe 1 through the buffer holes 10 on the buffer plate 9, energy loss will occur due to the friction and collision between the gas and the hole wall. This energy loss will directly reduce the impact force of the gas. The main manifestation is that when the gas passes through the buffer holes 10 on the buffer plate 9, it will be dispersed into multiple small airflows through the buffer holes 10. The impact force of each airflow will be less than the impact force of the original high-pressure gas, thereby reducing the impact force.

[0027] Example 3

[0028] like Figures 1 to 5 The pipeline safety pressure testing and explosion-proof device shown further includes multiple sliding grooves 6 on the left side of the mounting bracket 5. Slide plates 8 are connected to the sliding grooves 6 by springs 7, and buffer plates 9 are connected between the slide plates 8. Buffer plates 9 have multiple buffer holes 10. When gas flows from the left side of the pipeline body 1 to the right, it will be dispersed into multiple small streams of air through the buffer holes 10 on the buffer plate 9. The impact force of each stream of air will be less than the impact force of the original high-pressure gas, thereby reducing the impact force. During this period, the buffer plate 9 will also be forced to move to the right, reducing the direct impact force on the buffer plate 9 and preventing the buffer plate 9 from breaking or being damaged. When the buffer plate 9 is not under force, it will move to the left under the restoring force of the spring 7 to complete the reset.

[0029] However, when the impact force exceeds the threshold, after the buffer plate 9 is driven to move to the rightmost end of the chute 6 and continues to be stressed and tends to break away from the chute 6, it is very easy to cause the buffer plate 9 and the sliding plate 8 to break and rupture, affecting the service life of the device. Therefore, a plurality of balance baffles 17 are provided on the inner wall of the mounting seat 5. The balance baffles 17 are L-shaped and are arranged at intervals with the sliding plate 8. Their "|" is embedded in the inner wall of the mounting seat 5, and the "-" extends inward into the mounting seat 5 and is located at the position on the right side of the buffer plate 9. Then, when the buffer plate 9 moves to the right and contacts the balance baffle 17, the resistance generated by the balance baffle 17 can reduce the impact force received by the buffer plate 9, enhance the protection and stability of the buffer plate 9, and ensure the service life of the buffer plate 9 and the entire device.

[0030] Embodiment 4

[0031] As Figures 1 to 5 Shown is a pipeline safety pressure measurement and explosion-proof device. To further buffer high-pressure gas, a backwashing component 11 is also provided at the position on the right side of the inner wall of the pipeline main body 1. That is, in the case of a large amount of gas, by introducing a reverse air flow, that is, backwashing, a counter-force opposite to the direction of the original impact force can be generated. When the backwashing gas interacts with the original impact force, the two will generate a mutual force, offsetting part of the original impact force and slowing down the effect of the original impact force to a certain extent. The specific setting is as follows: On the right side of the inner wall of the pipeline main body 1, extension frames 111 extend inward. The extension frames 111 are in a state of spreading out in three legs, and a hinge block 112 is connected between the extension frames 111. The hinge block 112 is in a hollow state and is movably connected with a screw rod 114 through a threaded component 113. That is, the inner wall of the hollow part of the hinge block 112 has threads, and the screw rod 114 can rotate while moving left and right in the hinge block 112. Then, when a fan 115 is connected to the right side of the screw rod 114, the fan 115 can be driven to rotate by driving the screw rod 114 to move left and right.

[0032] In this embodiment, it is defined that when the screw rod 114 moves to the right, it will drive the wind of the fan 115 to blow to the left. That is, when the screw rod 114 moves to the right, it will drive the fan 115 to rotate, and the blown wind is on the left side, backwashing the incoming high-pressure gas and slowing down the impact force of this part of the high-pressure gas. It can be understood that the high-pressure gas will blow from the pipeline main body 1 to the right to the medium pipeline 3 and then to the pressure detection table 4 to complete pressure measurement. Before blowing to the medium pipeline 3, when the screw rod 114 moves to the right, it will drive the fan 115 to rotate, blowing out the wind flowing to the left. That is, the wind of the fan 115 and the high-pressure gas present two-directional forces, called the counter-force, and interact with the original impact force "high-pressure gas". The two generate a mutual force, and the force of the fan 115 can offset part of the original impact force brought by the high-pressure gas, ultimately achieving the effect of slowing down the impact force.

[0033] To achieve the movement of the screw 114, the initial impact force from the high-pressure gas is used as the power source. A gas collecting cylinder 13 is fixedly installed inside the main pipe body 1, with the cylinder at the center, i.e., on the same horizontal line as the screw 114. An air inlet 14 is located on the left side of the cylinder 13, and an air outlet 15 is located on the right side. As the high-pressure gas enters the main pipe body 1 through the buffer hole 10 and continues to flow to the right, the impact force in the center enters the gas collecting cylinder 13 through the air inlet 14, and then directly impacts to the right through the air outlet 15, driving the screw 114 to the right. Ultimately, this achieves the effect of using the fan 115 to reverse the impact force of the high-pressure gas.

[0034] However, the cross-section of the screw 114 is too small. It is foreseeable that the gas in the main body of the pipe 1 cannot push the screw 114. Therefore, a rotating seat 12 is provided at the outlet 15 on the right side of the gas collecting cylinder 13. The rotating seat 12 can be elastically slidably engaged with the gas collecting cylinder 13. Furthermore, the size of the rotating seat 12 can just cover the outlet 15. Thus, under normal conditions, the rotating seat 12 will block the gas collecting cylinder 13. When gas flows into the gas collecting cylinder 13 and an impact force is applied, the impact force will impact the rotating seat 12 to the right, causing it to move to the right. Furthermore, by simply connecting the left side of the screw 114 to the rotating seat 12 and allowing the connecting end of the screw 114 to rotate within the rotating seat 12, the screw 114 can be moved when the rotating seat 12 moves to the right. This movement of the screw 114 is unaffected by the rotation of the screw, which drives the fan 115 to operate and back-blow, reducing some of the impact force. This prevents the large impact force generated when too much gas rushes into the main body of the pipeline 1, thus avoiding damage to the pressure gauge 4 inside the pipeline 1 and ensuring the service life of the device. Understandably, a sliding hole 16 is also provided at the center of the buffer plate 9. The inner diameter of the sliding hole 16 is the same as the outer diameter of the gas collecting cylinder 13. The air inlet 14 of the gas collecting cylinder 13 extends to the left until it protrudes beyond the left side of the sliding hole 16. Therefore, when the gas collecting cylinder 13 guides the impact force in the center, it does not affect the rightward movement of the buffer plate 9. The buffer plate 9 can move on the gas collecting cylinder 13, buffering the impact force it bears.
