Technical Field

[0001] This utility model relates to the field of gas flow control technology, specifically a mixed gas flow control device. Background Technology

[0002] Gas flow control equipment is a device used to precisely adjust, monitor and control gas flow. It is widely used in many fields such as chemical, energy, medical, environmental protection and semiconductor. Its core objective is to ensure that the gas flow is stably delivered according to preset requirements to meet the needs of production processes, experimental research or safety protection.

[0003] Most existing mixed gas flow control devices use a lead screw to drive the movement of a pressure plate to activate the gas flow control device. However, the lead screw driving the pressure plate can only control the on / off switch for gas entry, and cannot control and adjust the flow rate of the gas as needed. This makes it inconvenient to use and affects work efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mixed gas flow control device to solve the problem mentioned in the background art. Most existing mixed gas flow control devices use a lead screw to drive the movement of a pressure plate to achieve the purpose of opening the gas flow control device. However, the lead screw driving the pressure plate can only control the opening and closing of the gas inlet, but cannot control and adjust the flow rate of the gas inlet as needed, which is inconvenient to use and affects work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixed gas flow control device, comprising a device body, an outlet pipe fixedly connected to the right end of the device body, an electronic gas flow meter disposed on the top right side of the device body, an inlet pipe one fixedly connected to the front left side of the device body, an inlet pipe two fixedly connected to the rear left side of the device body, a fixing ring fixedly connected to the inner middle side of the device body, a rubber ring fixedly connected to the inner side of the fixing ring, an electric push rod fixedly connected to the left end of the device body, an adjusting cylinder fixedly connected to the extension end of the electric push rod, a sealing ring fixedly connected to the left end of the adjusting cylinder, and an air inlet hole opened on the surface of the adjusting cylinder.

[0006] Preferably, there are several air inlets, which are arranged in a circular array on the surface of the regulating cylinder, and the spacing between the several air inlets is the same.

[0007] By adopting the above technical solution, and by setting up an air inlet, an adjusting cylinder, and other components in conjunction with a rubber ring, gas enters the interior of the adjusting cylinder through the air inlet and is then transported to the inner right side of the main body of the device. By moving the adjusting cylinder to the right side of the main body of the device, some of the air inlets can be moved to the inner right side, thereby reducing the number of air inlets, reducing the air intake efficiency, and realizing the adjustment of gas flow rate, which is convenient to use.

[0008] Preferably, the diameter of the air inlet is the same as the inner wall diameter of the rubber ring, and the surface of the air inlet is in contact with the inner wall of the rubber ring.

[0009] Preferably, it also includes a PLC controller, the electric push rod is electrically connected to the PLC controller, and the PLC controller is electrically connected to the electronic gas flow meter.

[0010] By adopting the above technical solution, and by setting up an electric push rod and a PLC controller, the PLC controller can control the electric push rod to extend and retract, thereby automatically adjusting the position of the regulating cylinder inside the rubber ring. This achieves the function of automatically adjusting the incoming gas flow rate, eliminating the need for manual control by the operator, reducing the labor intensity of the operator, and making it easier for the operator to use.

[0011] Preferably, the sealing ring is located on the outer surface of the adjusting cylinder, and the diameter of the sealing ring is larger than the diameter of the rubber ring.

[0012] By adopting the above technical solution, and by setting a sealing ring and adjusting cylinder in conjunction, the sealing ring can be moved to the right and tightly fitted with the rubber ring by sliding the adjusting cylinder inside the rubber ring. This prevents gas from escaping from the adjusting cylinder, realizes the opening and closing of the airflow, and is convenient to use. Preferably, the extension end of the electric push rod passes through the left wall of the device body and extends to the inner left side of the device body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This mixed gas flow control device, through the use of an air inlet, regulating cylinder, and rubber ring, allows gas to enter the regulating cylinder through the air inlet and be transported to the inner right side of the main body of the device. By moving the regulating cylinder to the right side of the main body of the device, some of the air inlets can be moved to the inner right side, thereby reducing the number of air inlets, reducing the air intake efficiency, and realizing the regulation of gas flow, making it convenient to use.

[0014] 2. This mixed gas flow control device, through the use of an electric push rod and a PLC controller, allows the electric push rod to extend and retract, thereby automatically adjusting the position of the regulating cylinder inside the rubber ring. This achieves the function of automatically adjusting the incoming gas flow, eliminating the need for manual control by operators, reducing the labor intensity of operators, and making it convenient for operators to use.

[0017] 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.

[0018] Example 1: Please refer to the following: Figure 1-5A mixed gas flow control device includes a main body 1, an outlet pipe 2 fixedly connected to the right end of the main body 1, an electronic gas flow meter 3 installed on the top right side of the main body 1, an inlet pipe 4 fixedly connected to the front left side of the main body 1, an inlet pipe 5 fixedly connected to the rear left side of the main body 1, a fixing ring 8 fixedly connected to the inner side of the main body 1, a rubber ring 9 fixedly connected to the inner side of the fixing ring 8, and an electric push rod 7 fixedly connected to the left end of the main body 1. The extension end of the electric push rod 7 penetrates the left wall of the main body 1 and extends into the interior of the main body 1. On the left side, an adjusting cylinder 10 is fixedly connected to the extension end of the electric push rod 7. The diameter of the air inlet 12 is the same as the inner wall diameter of the rubber ring 9, and the surface of the air inlet 12 is in contact with the inner wall of the rubber ring 9. A sealing ring 11 is fixedly connected to the left end of the adjusting cylinder 10. The sealing ring 11 is located on the outer side of the surface of the adjusting cylinder 10, and the diameter of the sealing ring 11 is larger than the diameter of the rubber ring 9. An air inlet 12 is opened on the surface of the adjusting cylinder 10. There are several air inlets 12, and the several air inlets 12 are distributed in a ring array on the surface of the adjusting cylinder 10, and the spacing between the several air inlets 12 is the same.

[0019] Working principle: During use, the operator inputs the gases to be mixed into the main body 1 of the device through inlet pipe 4 and inlet pipe 5 respectively. The gases are mixed inside the main body 1 and enter the regulating cylinder 10 through inlet hole 12. The regulating cylinder 10 delivers the gases to the right side of the main body 1 and then discharges them through outlet pipe 2. The electronic gas flow meter 3 can detect the gas flow rate in real time. When the operator needs to adjust the gas flow rate, the electric push rod 7 extends from the inside to push the regulating cylinder 10 inside the rubber ring 9 to the right side of the main body 1. This moves some of the inlet holes 12 to the right side, thereby reducing the number of inlet holes 12 and reducing the intake efficiency. Conversely, moving them to the right will increase the intake efficiency. When the regulating cylinder 10 moves to the right inside the rubber ring 9, it will move the sealing ring 11 to the right and make it tightly fit the rubber ring 9, thus preventing the gas from escaping from the regulating cylinder 10. This realizes the opening and closing of the gas flow rate, thereby achieving the adjustment of the gas flow rate and making it convenient to use.

[0020] Compared with related technologies, the mixed gas flow control device provided by this utility model has the following beneficial effects: by setting an air inlet 12, an adjusting cylinder 10 and other components in conjunction with a rubber ring 9, gas enters the interior of the adjusting cylinder 10 through the air inlet 12 and is transported to the inner right side of the device body 1 through the adjusting cylinder 10. By moving the adjusting cylinder 10 to the right side of the device body 1, some of the air inlets 12 can be moved to the inner right side, thereby reducing the number of air inlets 12, reducing the air intake efficiency, realizing the adjustment of gas flow, and facilitating use.

[0021] Example 2: Please refer to the following: Figure 1-6The right end of the main body 1 is fixedly connected to the air outlet pipe 2. The top right side of the main body 1 is equipped with an electronic gas flow meter 3. The front left side of the main body 1 is fixedly connected to the air inlet pipe 4. The rear left side of the main body 1 is fixedly connected to the air inlet pipe 5. The inner middle side of the main body 1 is fixedly connected to the fixing ring 8. The inner side of the fixing ring 8 is fixedly connected to the rubber ring 9. The left end of the main body 1 is fixedly connected to the electric push rod 7. The electric push rod 7 is electrically connected to the PLC controller 6. The PLC controller 6 is electrically connected to the electronic gas flow meter 3. The extension end of the electric push rod 7 is fixedly connected to the regulating cylinder 10.

[0022] Working principle: When the operator needs to adjust the air flow, the operator can control the electric push rod 7 to extend and retract through the PLC controller 6, thereby automatically adjusting the position of the regulating cylinder 10 inside the rubber ring 9, realizing the function of automatically adjusting the incoming gas flow. No manual control is required, which reduces the labor intensity of the operator and makes it convenient for the operator to use.

[0023] Compared with related technologies, the mixed gas flow control device provided by this utility model has the following beneficial effects: by setting up an electric push rod 7 and a PLC controller 6 for use together, the PLC controller 6 can control the electric push rod 7 to extend and retract, thereby automatically adjusting the position of the regulating cylinder 10 inside the rubber ring 9, realizing the function of automatically adjusting the inlet gas flow, eliminating the need for manual control by the staff, reducing the labor intensity of the staff, and making it convenient for the staff to use.
