Description

Technical Field

[0001] This utility model relates to the technical field of nitrogen booster equipment, and in particular to a nitrogen booster device. Background Technology

[0002] Currently, nitrogen's inert properties are commonly used in many industries and for various products to protect them from oxidation, moisture, or other harmful substances; this is also known as nitrogen purging. Some companies produce their own nitrogen, but this often has lower pressure, while products require higher purging pressures, and the purging process needs to maintain stable and uniform pressure to ensure product quality. Consequently, the pressure of company-produced nitrogen often cannot meet production needs. While purchasing bottled nitrogen can meet production requirements, it is more expensive and inconvenient to operate. Furthermore, when nitrogen is rapidly introduced into equipment, the high gas velocity can easily create instantaneous pressure fluctuations or impacts in the pipelines, known as the air hammer effect. These pressure impacts can not only accelerate wear on pipes, valves, or joints but also easily lead to leaks. Utility Model Content

[0003] The purpose of this invention is to address the problem that some companies cannot meet their production needs by using self-made nitrogen, while purchasing bottled nitrogen can meet production needs, but the cost of purchasing it is high and it is inconvenient to operate. Therefore, this invention proposes a nitrogen pressurization device.

[0005] Optionally, the alarm mechanism includes a controller mounted on the second L-shaped branch pipe, a pressure monitor fixedly connected to the second L-shaped branch pipe, an alarm fixedly connected to the top of the controller, an input terminal of the controller connected to the pressure monitor, and an output terminal of the controller connected to the alarm.

[0006] Optionally, the second L-shaped branch pipe is also equipped with a pressure regulating valve and a second shut-off valve.

[0007] Optionally, each of the branch pipes is provided with a first shut-off valve in the middle, and the ends of the plurality of first shut-off valves away from the first L-shaped branch pipe are fixedly connected to the air inlet pipe.

[0008] Optionally, a pair of support rods are fixedly connected to the top of the gas storage tank, and the top of the support rods is fixedly connected to the bottom of the pressure boosting valve.

[0009] Optionally, a connecting pipe is also fixedly connected to the top of the gas storage tank, and the end of the connecting pipe away from the gas storage tank is fixedly connected to the pressure boosting valve.

[0010] Optionally, a pressure gauge is fixedly connected to the upper surface of the end of the gas storage tank away from the second L-shaped branch pipe.

[0011] Optionally, a pair of support bases for supporting the gas storage tank are fixedly connected to the bottom of the gas storage tank.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes a combination of a pressure boosting valve, a first L-shaped branch pipe, a second L-shaped branch pipe, a diverter pipe, and an alarm mechanism to stabilize the output pressure of nitrogen gas through a pressure boosting device, thus avoiding production risks caused by pressure fluctuations. Simultaneously, it ensures that the required nitrogen quantity and pressure conditions are met at each production stage, reducing production stoppages or interruptions due to insufficient pressure.

[0014] Furthermore, when nitrogen enters the first L-shaped branch pipe through multiple split pipes, the design of multiple split pipes allows the airflow to be dispersed before entering the first L-shaped branch pipe, thus making the impact force of the airflow relatively small.

[0025] Example

[0026] like Figures 1 to 3As shown, this utility model proposes a nitrogen booster device, including a gas storage tank 1 and a booster valve 2 fixedly installed on the top of the gas storage tank 1. The booster valve 2 is a device used to regulate the pressure in a gas or liquid system. Its main function is to increase the pressure in the system to the required value through a booster device. Its working principle is to control the flow rate and pressure of the fluid to ensure that the output pressure reaches a certain standard. It is commonly used in systems that require stable and precise air or hydraulic pressure. A pair of support seats 11 are fixedly connected to the bottom of the gas storage tank 1, and a pair of support rods 22 are fixedly connected to the top of the gas storage tank 1. The top of the support rods 22 is fixedly connected to the bottom of the pressure boosting valve 2. A connecting pipe 21 is also fixedly connected to the top of the gas storage tank 1. The end of the connecting pipe 21 away from the gas storage tank 1 is fixedly connected to the pressure boosting valve 2. A first L-shaped branch pipe 3 is fixedly connected to the upper surface of one end of the pressure boosting valve 2, and a second L-shaped branch pipe 4 is fixedly connected to the upper surface of one end of the gas storage tank 1. A pressure gauge 12 is fixedly connected to the upper surface of the end of the gas storage tank 1 away from the second L-shaped branch pipe 4. The pressure gauge 12 is an instrument used to measure the pressure of gas or liquid in a closed system and is widely used in industry, machinery, chemical industry, energy and other fields. It can display the pressure value in real time to help monitor the operating status of the system and ensure the normal operation and safety of the equipment. A pressure regulating valve 41 and a second shut-off valve 42 are also provided on the second L-shaped branch pipe 4. The pressure regulating valve 41 is a device used to regulate and control the pressure in a fluid (liquid or gas) system. It can automatically adjust the flow of fluid according to the set pressure range to ensure that the pressure in the system is maintained at a safe and stable level; a diversion pipe 31 is set on the first L-shaped branch pipe 3 to divert the nitrogen entering the first L-shaped branch pipe 3. Each diversion pipe 31 is equipped with a first shut-off valve 32 in the middle. The first shut-off valve 32 and the second shut-off valve 42 are also called shut-off valves. They are valves used to control the flow of fluid in pipelines. Their main function is to open, close or regulate the flow of fluid. Its structure usually includes valve body, valve seat, valve disc, valve stem and other components. It can control the flow of fluid by raising and lowering the valve disc. The ends of multiple first shut-off valves 32 away from the first L-shaped branch pipe 3 are fixedly connected to the air inlet pipe 33; an alarm mechanism is installed on the second L-shaped branch pipe 4 to monitor the pressure of nitrogen passing through the second L-shaped branch pipe 4 in real time.

[0027] Furthermore, such as Figure 2As shown, the alarm mechanism includes a controller 44 mounted on the second L-shaped branch pipe 4. The controller 44 is a device or apparatus for regulating and managing system behavior. It controls the output device based on input signals or environmental changes, thereby achieving automated management and regulation of the system. The basic function of the controller is to adjust the system state to achieve the expected effect according to the set target or instructions. A pressure monitor 43 is also fixedly connected to the second L-shaped branch pipe 4. The pressure monitor 43 is an instrument used to measure the pressure of gas or liquid. It helps monitor and control the pressure in the system to ensure the normal operation of equipment or processes. An alarm 45 is fixedly connected to the top of the controller 44. The alarm 45 is a device used to issue alarm signals. It can detect abnormal situations or danger signals under specific conditions and alert users or relevant personnel through sound, light signals, or other means. Alarms are commonly used to improve safety, prevent accidents, or respond to emergencies. The input terminal of the controller 44 is connected to the pressure monitor 43, and the output terminal of the controller 44 is connected to the alarm 45.

[0028] In this embodiment, when a nitrogen pressurization device is required, such as Figure 1 As shown, nitrogen gas is first transported through the inlet pipe 33 to multiple branch pipes 31. When the nitrogen gas enters the first L-shaped branch pipe 3 through the multiple branch pipes 31, the design of the multiple branch pipes 31 disperses the airflow before it enters the first L-shaped branch pipe 3, reducing the airflow velocity in each branch pipe 31 and thus reducing the impact force of the airflow. At the same time, the multiple branch pipes 31 help to evenly distribute the pressure of the nitrogen gas, and the flow of nitrogen gas in multiple branch pipes 31 also avoids the first L-shaped branch pipe 3 from bearing excessive pressure, thereby reducing the severity of pressure fluctuations. Then, the nitrogen gas enters the gas storage tank 1 through the first L-shaped branch pipe 3 on the pressure boosting valve 2, and then is transported elsewhere through the second L-shaped branch pipe 4. When nitrogen passes through the second L-shaped branch pipe 4, the pressure monitor 43 will measure the pressure of the gas inside the second L-shaped branch pipe 4 in real time. When the gas pressure inside the second L-shaped branch pipe 4 is too high or too low, the pressure monitor 43 will send a signal to the controller 44. After receiving the signal, the controller 44 will send a command to the alarm 45. The alarm 45 will sound an alarm to alert the technicians so that they can take appropriate measures.

[0029] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
