Description

Technical Field

[0001] The invention relates to the technical field of two-position three-way valve group structures, and in particular to a novel two-position three-way valve group structure. Background Art

[0002] The two-position three-way valve group is a common fluid control device, which is mainly used to control the flow direction and flow rate of the fluid. It consists of a valve body and three connecting ports, and is usually used for the flow control of gas or liquid.

[0003] However, most traditional two-position three-way valves may not be designed with guide structures inside the exhaust pipe and the intake pipe, which may cause gas backflow inside the valve body, increasing the risk of failure and maintenance costs. In addition, traditional two-position three-way valves may require additional connectors to connect the valve body to external pipes, which increases the complexity of installation and reduces system efficiency.

[0004] Therefore, those skilled in the art provide a novel two-position three-way valve group structure to solve the problems raised in the above background technology. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose a new type of two-position three-way valve group structure. The air inlet and exhaust port of the two-position three-way valve adopt advanced injection molding technology and are directly formed into pagoda joints. This design allows the cannula to be directly connected to the valve without the need for additional installation of pagoda joints, thereby reducing potential sealing points and reducing the risk of leakage. At the same time, ultrasonic welding technology is used to connect the valve body to the upper and lower covers. This welding method not only reduces the number of required seals, but also significantly reduces leakage points, making the entire valve structure more reliable and safe. The application of these innovative manufacturing processes and technologies improves the overall performance of the valve and ensures stability and durability under various working conditions.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A novel two-position three-way valve group structure comprises a valve body, connecting rods are arranged at both ends of the inner wall of the valve body, an air inlet pipe is connected through the lower part of the rear end of the outer wall of the valve body, an exhaust pipe is connected through the upper part of the front end of the outer wall of the valve body, exhaust structures are arranged inside the air inlet pipe and the exhaust pipe, and the two exhaust structures comprise a sliding rod, and a fixing plate is fixedly connected to one end of the sliding rod away from the valve body;

This action pushes the sealing plate away from the valve body, ensuring that the exhaust pipe is only used for exhaust to avoid gas backflow. This design not only improves the functionality of the valve, but also enhances the safety and efficiency of the system. In this way, the valve can control the flow direction of gas and liquid, ensure that the gas flows along a predetermined path in the system, thereby optimizing the performance of the entire system.

[0015] Through the above technical solution, an upper sealing cover is provided at the upper end of the upper diaphragm, and a lower diaphragm sealing cover is provided at the lower end of the lower diaphragm. The use of these sealing covers further enhances the sealing effect of the valve, prevents leakage of gas or liquid, and ensures the reliability of the valve under various working conditions.

[0016] Furthermore, a process hole plug is provided at the lower end of the middle portion of one side of the inner wall of the valve body;

[0017] Through the above technical solution, a process hole plug is provided at the lower end of the middle part of one side of the inner wall of the valve body.

[0018] Furthermore, an A1 port is provided at the front end of the outer wall of one side of the valve body, and an A2 port is provided at the rear end of the outer wall of one side of the valve body;

[0019] Through the above technical solution, an A1 port is opened at the front end of the outer wall of one side of the valve body, and an A2 port is opened at the rear end of the outer wall of one side of the valve body.

[0022] The present invention has the following beneficial effects:

[0023] 1. The present invention proposes a novel two-position three-way valve group structure, in which exhaust structures are arranged inside the exhaust pipe and the intake pipe of the two-position three-way valve to ensure unidirectional flow of gas.

This action enables the gas to push the sealing plate into the interior of the valve body, thereby ensuring that the intake pipe is only used for air intake and backflow is prevented. Similarly, when exhaust or liquid is discharged, the gas enters the interior of the connecting pipe through the air permeable groove opened on the fixed plate inside the exhaust pipe. This action pushes the sealing plate away from the interior of the valve body, ensuring that the exhaust pipe is only used for exhaust and gas backflow is avoided.

These air permeable grooves 807 help to optimize gas flow, reduce gas flow resistance, and improve gas flow efficiency, while also helping to reduce noise and vibration.

[0041] Working principle: Connect the air inlet pipe 3 to the air source to ensure that the gas can flow smoothly into the valve body 1. At the same time, connect the exhaust pipe 2 to the exhaust part of the system or discharge it directly into the atmosphere so that the gas can be effectively discharged. The A1 port 14 and the A2 port 15 need to be connected to the corresponding actuators or devices, such as cylinders or other components that need to control the airflow. The connection of these ports will be determined according to specific needs and designs to ensure that the gas can flow along the predetermined path. At the upper end of the valve body 1, the upper cover 5 is fixed by bolts. A coil 4 is installed on one side of the upper cover 5. The coil 4 is responsible for the operation of the electromagnetic control valve. When the coil 4 is energized, the magnetic field generated will drive the connecting rod 10 and the diaphragm in the valve body 1, thereby changing the fluid. In order to ensure the sealing performance of the valve, an upper sealing cover 6 is installed on the upper end of the upper diaphragm 7, and a lower diaphragm sealing cover 12 is installed on the lower end of the lower diaphragm 11.

In terms of maintenance and testing, the process hole plug 9 provides access to the inside of the valve body 1 for necessary inspection and maintenance work. The entire valve body 1 and the upper cover 5 are connected by ultrasonic welding technology. This connection method not only reduces the use of seals, but also reduces potential leakage points, thereby improving the reliability and safety of the entire valve system. When operating the valve, current is supplied to the coil 4 as needed to control the flow of gas through the valve, thereby realizing fluid control.
