Description

Technical Field

[0001] This utility model relates to the field of gas compressor technology, specifically a backflow prevention structure for the gas compressor intake valve. Background Technology

[0002] A gas compressor is a mechanical device that compresses and increases the pressure of gas. It converts mechanical energy into the pressure energy of gas. Gas compressors play a vital role in various industrial and civil fields. Specifically, the working principle of a gas compressor is to reduce the volume of gas by mechanical means, thereby increasing the gas pressure. Gas compressors are widely used in industries such as petrochemicals, drilling and mining, metallurgy, pharmaceuticals, food, and electronics, providing necessary gas power for various equipment and processes. With the development of technology and changes in market demand, the types and functions of gas compressors are constantly expanding and improving. The intake valve of a gas compressor is a key component. Its main function is to control the process of gas entering the compressor cylinder. The intake valve is usually located at the suction end of the compressor and is responsible for opening during the suction stroke of the compressor to allow gas to enter.

[0003] Based on existing gas compressor inlet valve technology, it has been found that the inlet valve relies on the valve seat seal for backflow prevention. The gas compressor inlet valve mainly relies on the precision seal of the valve seat to prevent gas backflow. However, in actual operation, when it is necessary to close the inlet valve to stop the gas flow, due to the characteristics of the mechanical structure and control system, the valve closing action is not completed instantaneously, but requires a certain time period. During this period, due to inertia and the existence of pressure difference, gas backflow is difficult to completely avoid. If an external anti-backflow structure is added, the overall sealing performance of the valve body will be reduced. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, an anti-backflow mechanism is provided. The anti-backflow mechanism adopts a double-sealing structure, which can respond quickly and seal, effectively preventing the backflow of gas during the valve closing process, thereby maintaining the stability and safety of the system. The first layer of the anti-backflow structure achieves unidirectional airflow and bidirectional anti-backflow through the cooperation of the first rubber plate and the second rubber plate, improving the sealing performance of the intake valve.

By converting the kinetic energy of the airflow into electrical energy, the energy storage mechanism improves the overall energy efficiency of the system. The design of the energy storage mechanism avoids the introduction of external power, thus ensuring the sealing performance of the entire system without damaging the air intake valve.

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.

[0026] Please see Figures 1-7In this embodiment of the present invention, a backflow prevention structure for a gas compressor intake valve includes a valve chamber 1. A first gas pipe 2 is fixedly connected to the left end of the valve chamber 1, and a second gas pipe 3 is fixedly connected to the right end of the valve chamber 1. A sealing valve seat 4 is installed inside the valve chamber 1. An energy storage mechanism 6 and a backflow prevention mechanism 5 are provided on the right side of the second gas pipe 3. The backflow prevention mechanism 5 includes a drive chamber 502, an electric push rod 503, and a rubber plug 504. The electric push rod 503 is fixedly installed inside the drive chamber 502. The transmission end of the electric push rod 503 is fixedly connected to a rubber plug 504. The anti-backflow mechanism 5 also includes an air supply pipe 501, a first slot 505, a first sealing gasket 506, a second sealing gasket 507, a second slot 508, a first rubber plate 509, and a second rubber plate 510. The right end of the second air pipe 3 is fixedly connected to the air supply pipe 501. The inner wall of the air supply pipe 501 is provided with a first slot 505 and a second slot 508. The second slot 508 is located in the first slot. On the right side of 505, a first sealing gasket 506 is fixedly installed at the left end of the first slot 505, and a second sealing gasket 507 is fixedly installed at the right end of the first slot 505. A first rubber plate 509 and a second rubber plate 510 are installed inside the second slot 508, and the first rubber plate 509 and the second rubber plate 510 are in contact with each other. The first rubber plate 509 and the second rubber plate 510 constitute the first layer of anti-backflow structure, which allows the rubber plates to unfold naturally when the airflow is flowing in the forward direction without obstructing the airflow, and to quickly flip and fit together when the airflow is flowing in the reverse direction, thereby achieving an effective anti-backflow function. The electric push rod 503 is a key component of the second layer of anti-backflow structure, which can quickly push the rubber plug 504 to seal the first slot 505, thereby preventing gas backflow when the valve is closed, ensuring the reliability and stability of the sealing performance. The rubber plug 504 has excellent sealing performance and can tightly fill the first slot 505, effectively preventing gas backflow.

[0027] The energy storage mechanism 6 includes a fan blade body 603 and a generator 604. The fan blade body 603 is fixedly installed on the transmission end of the generator 604. The energy storage mechanism 6 also includes an energy storage compartment 601, a wind duct 602, and an energy storage control compartment 605. The fan blade body 603 is located inside the wind duct 602. The energy storage compartment 601 is fixedly installed on the outside of the generator 604. The wind duct 602 is opened at the front end of the energy storage compartment 601, and the energy storage control compartment 605 is fixedly installed at the rear end of the energy storage compartment 601. The energy storage control compartment 605 is connected to the generator. 604 Electrical connection; the air duct 602 can effectively guide the airflow and increase the impact force of the airflow on the fan blade 603, thereby improving the power generation efficiency. The fan blade 603 can utilize the high-speed rotation generated by the airflow to effectively convert it into mechanical energy, which in turn drives the generator 604 to generate electricity, realize energy recovery, and improve the overall energy of the system. The generator 604 efficiently converts the mechanical energy of the fan blade 603 into electrical energy, stores it in the energy storage control compartment 605, and provides power to the electric push rod 503 to achieve self-powered operation.

[0028] The working principle of this utility model is as follows: The gas compressor inlet valve anti-backflow structure is equipped with an anti-backflow mechanism 5 and an energy storage mechanism 6. When using this gas compressor inlet valve anti-backflow structure, when the airflow passes through the energy storage mechanism 6, the airflow rushes into the air duct 602, causing the fan blade 603 to rotate at high speed, thereby cooperating with the generator 604 to generate electricity and storing the electrical energy in the energy storage control chamber 605. The energy storage control chamber 605 is used to supply power to the electric push rod 503 in the anti-backflow mechanism 5. When the airflow passes through the gas delivery pipe 501, the second slot 508, the first rubber plate 509, and the second rubber plate 510 form the first layer of anti-backflow structure. The first rubber plate 509 and the second rubber plate 510 are located on the far left of the second slot 508. When the airflow is delivered to the right, the first rubber plate 509 and the second rubber plate 510 unfold to the right without affecting the airflow delivery. When the airflow flows back, the first rubber plate 509 and the second rubber plate 510 flip to the left and are blocked by the second slot 508. When the second rubber plate 510 and 509 are bonded together, the airflow cannot flow back. The drive chamber 502, electric push rod 503, rubber plug 504, first slot 505, first sealing gasket 506, and second sealing gasket 507 form a second anti-backflow structure. The electric push rod 503 pushes the rubber plug 504 forward, so that the rubber plug 504 is stably inserted into the first slot 505, achieving the effect of sealing the first slot 505, thereby preventing the airflow from flowing back. In summary, the anti-backflow mechanism 5 adopts a double-sealing structure, which can quickly seal the pipeline and prevent gas from flowing back into the valve chamber 1, effectively improving the reliability and stability of the intake valve and reducing the probability of backflow. The energy storage mechanism 6 can achieve a micro wind power generation effect by utilizing the airflow in the intake valve. It can perform internal power supply operation without opening a slot to connect to the power from the outside, ensuring the sealing of the intake valve. Both the anti-backflow mechanism 5 and the energy storage mechanism 6 are installed on the pipeline and have no impact on the sealing of the intake valve.
