Description

Technical Field

[0001] This utility model belongs to the field of pneumatic valve technology, and particularly relates to a pneumatic two-way angle valve. Background Technology

[0002] As a conveying control component, the pneumatic angle valve's main function is to control the conveying medium inside a fixed gas or liquid conveying pipe. When it is necessary to control the conveying medium inside the conveying pipe, gas can be delivered to the cylinder via an external gas conveying component, driving the valve plug to move and controlling the opening and closing of the conveying pipe, thereby controlling the conveying medium. However, existing two-way angle valves lack installation and adjustment components, making it impossible to adjust the installation position of the two-way angle valve according to usage needs during installation. Furthermore, traditional two-way angle valves often use a sealing ring for the valve stem, which can easily reduce the sealing performance after frequent opening and closing, making them unsuitable for applications requiring high sealing performance. Utility Model Content

[0003] To achieve the above objectives, the present invention adopts the following technical solution:

[0004] A pneumatic two-way angle valve includes a valve body and an input end. The input end is provided at the lower end of the valve body, and the output end is provided on the side of the valve body. A valve core is sealed and rotated inside the valve body. A valve stem is connected to the top of the valve core. An actuator is fixedly connected to the top of the valve stem, and the actuator is sealed to the valve body.

[0005] Preferably, the output end is threadedly connected to a valve cover, the valve cover is provided with a gasket on the side away from the valve body, the gasket is provided with a connecting pipe on the side away from the valve cover, and a hexagonal cap is fitted on the outside of the connecting pipe, the hexagonal cap being threadedly connected to the end of the valve cover.

[0006] Preferably, an annular limiting groove is provided on the circumferential side wall of the valve stem, and an O-ring is provided in the annular limiting groove.

[0007] Preferably, a triangular connector is fixedly connected to the upper end of the valve body, and the triangular connector is provided with three connection holes.

[0008] Preferably, the actuator uses either an electric actuator or a pneumatic actuator as the power source to drive the valve stem rotation.

[0009] Preferably, one end of the connector is provided with an outwardly extending annular flange, and one end of the hexagonal cap is provided with an inwardly extending annular protrusion. The annular flange and the annular protrusion abut against each other to seal the connector, gasket and valve cover tightly.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This utility model adds a triangular connector and a connecting hole. When it is necessary to adjust the fixed position of the two-way angle valve, the external bolt can be inserted into different connecting holes by external force. The fixed position of the two-way angle valve can be adjusted by the triangular shape of the fixing plate. By setting two annular limiting grooves on the valve stem and setting O-rings in the annular limiting grooves, the sealing performance of the angle valve can be improved, making the device suitable for vacuum systems with higher sealing requirements.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Reference Figures 1-6A pneumatic two-way angle valve includes a valve body 1 and an input end 2. The input end 2 is located at the lower end of the valve body 1. The valve body 1 provides a fixing point for the input end 2, output end 3, valve core 4, and actuator 6 connected to its outer surface and internally. The input end 2 is connected to an external input pipeline. When gas or liquid is delivered to the inside of the input end 2, the input end 2 delivers the gas or liquid into the inside of the valve body 1. The output end 3 is located on the side of the valve body 1. The output end 3 extends to the side of the valve body 1 and provides a fixing point for the valve cover 7, which is threaded to its inner side. The valve core 4 is sealed and rotated inside the valve body 1. The valve core 4 is fitted into the inside of the valve body 1. When external force is transmitted to the inside of the valve core 4 through the valve stem 5, the valve core 4 rotates, driving the inside of the valve body 1 to connect or block. A valve stem 5 is connected to the top of the valve core 4. When external force is transmitted to the inside of the valve stem 5 via the actuator 6, the valve stem 5 transmits the external force to the inside of the valve core 4. The actuator 6 is fixedly connected to the top of the valve stem 5, and the actuator 6 is sealed to the valve body 1. The actuator 6 is composed of a motor or a cylinder. When it is necessary to drive the internal connection or blockage of the valve body 1, gas can be delivered to the cylinder or electrical energy can be delivered to the inside of the motor via an external control component to transmit the external force to the inside of the valve stem 5. A valve cover 7 is threaded to the output end 3. The valve cover 7 is threaded to the inside of the output end 3 to provide a connection point for the gasket 8 set on one side of the valve body 1. The gasket 8 is set on the side of the valve cover 7 away from the valve body 1. On one side of the valve stem 8, a connection point is provided for the connecting pipe 9. The gasket 8 is located on the side away from the valve cover 7, and the connecting pipe 9 connects to an external output pipe to complete the output of gas or liquid. A hexagonal cap 10 is fitted on the outside of the connecting pipe 9, and the hexagonal cap 10 is threaded to the end of the valve cover 7. The hexagonal cap 10 is fixed via the valve cover 7 and the annular protrusion 16, facilitating subsequent disassembly of the connecting pipe 9. Two annular limiting grooves 11 are provided on the circumferential sidewall of the valve stem 5. The annular limiting grooves 11 are located on the outer surface of the valve stem 5, providing fixing points for the O-ring seals 12 located on their inner sides. O-ring seals 12 are installed inside the annular limiting grooves 11, and are fixedly connected to the inner side of the annular limiting grooves 11, improving the sealing effect when the valve stem 5 moves. (Actuator) 6. One of the electric actuators and pneumatic actuators is used as the power source to drive the valve stem 5 to rotate. One end of the connecting pipe 9 is provided with an outwardly extending annular flange 15. The annular flange 15 is provided at one end of the connecting pipe 9 and cooperates with the annular protrusion 16 to complete the connection between the hexagonal cap 10 and the connecting pipe 9. One end of the hexagonal cap 10 is provided with an inwardly extending annular protrusion 16. The annular protrusion 16 is provided at one end of the hexagonal cap 10 and cooperates with the annular flange 15 to complete the connection between the hexagonal cap 10 and the connecting pipe 9. The annular flange 15 and the annular protrusion 16 abut against each other to seal the connecting pipe 9, the gasket 8 and the valve cover 7 tightly. This design can avoid the shaking of the connecting pipe 9 during transportation or use from affecting the sealing performance of the connection. It also makes it easier to replace the gasket 8 and makes the angle valve easier to maintain.

[0022] Reference Figure 1 , Figure 2 and Figure 7 A triangular connector 13 is fixedly connected to the upper end of the valve body 1. The triangular connector 13 provides a fixing point for the connection hole 14 set on its top. The triangular connector 13 is provided with three connection holes 14. The connection holes 14 are connected to the external bolts and the external bolts are connected to the external fixing plane to complete the fixing of the two-way angle valve. When it is necessary to adjust the fixing position of the two-way angle valve, the external bolts can be inserted into different connection holes 14 by external force to adjust the fixing position of the two-way angle valve.

[0023] The functional principle of this utility model can be explained through the following operation: First, connect the inside of the input end 2 of the connecting pipe, and then insert the external output pipe into the inside of the connecting pipe 9. When gas or liquid is delivered to the inside of the input end 2, the input end 2 delivers the gas or liquid to the inside of the valve body 1. The valve body 1 delivers the gas or liquid through the valve cover 7 and the connecting pipe 9 to the inside of the external output pipe, completing the output of gas or liquid. When it is necessary to block the gas or liquid, gas or electrical energy can be delivered to the inside of the actuator 6 through the external control component. At this time, the actuator 6 transmits the external force to the inside of the valve stem 5. At this time, the valve stem 5 transmits the external force to the inside of the valve core 4, driving the valve core 4 to rotate, blocking the inside of the valve body 1, and completing the blocking of gas or liquid.
