Description

Technical Field

[0001] This utility model relates to the field of pneumatic tool valve seat technology, and in particular to a novel pneumatic tool valve seat. Background Technology

[0002] A pneumatic tool valve seat is a core functional component used in pneumatic tool systems to achieve gas transmission, pressure control, and component connection and fixation. From a functional perspective, its primary role is to act as a hub for gas flow, guiding compressed gas from the gas source into the system through a specially designed channel, and then outputting it to the actuator of the pneumatic tool after passing through the internal flow path, providing power for the tool's operation.

[0003] Existing valve seat gas transmission channel sealing structures mostly employ simple sealing ring structures. These simple sealing rings only need to be embedded in corresponding slots, requiring minimal skill from installers and facilitating quick assembly and disassembly. This benefits routine equipment maintenance and replacement of sealing components. Maintenance only requires disassembling the component to replace the failed sealing ring, resulting in low maintenance costs and suitability for scenarios requiring frequent maintenance.

[0004] While simple sealing ring structures are easy to install and maintain, they are easily deformed under high-pressure gas impact, and may even be squeezed into gaps, causing tearing and gas leakage, which cannot meet the requirements of industrial-grade high-pressure pneumatic systems. Moreover, in scenarios requiring precise air pressure control, such as pneumatic servo systems and precision pneumatic instruments, even minor leaks in the sealing ring can lead to pressure fluctuations, affecting tool accuracy and machining quality. Therefore, a novel pneumatic tool valve seat is proposed to address these issues. Utility Model Content

[0028] 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.

[0029] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a novel pneumatic tool valve seat, comprising a valve body 1, with an inlet pipe 4 and an outlet pipe 8 respectively disposed on both sides of the valve body 1. A fixed platform 7 is disposed at the bottom of the valve body 1, and a connecting flange 11 is disposed at the top of the valve body 1. An inlet sealing thread 5 is disposed on the outer side of the inlet pipe 4, and an inlet port 6 is disposed on the inner side of the inlet pipe 4, serving as a channel for gas entry. An external air source is connected and fixed through the inlet sealing thread 5 on the outer side of the inlet pipe 4, and gas enters the valve body 1 from the inlet port 6 on the inner side of the inlet pipe. Two fixing threads 13 are disposed on the inner side of the fixed platform 7, used to securely fix the valve seat to a bracket. The fixing threads 13 on the inner side of the fixed platform 7 are used to bolt the valve seat to the bracket, ensuring the valve seat is stable in its working position and preventing displacement due to vibration or impact. An outlet sealing thread 9 is disposed on the outer side of the outlet pipe 8, and an outlet port 10 is disposed on the inner side of the outlet pipe 8, serving as a channel for gas outflow. Gas flows out from the outlet 10 inside the outlet pipe 8 and connects to the pneumatic tool through the outlet sealing thread 9 on the outside of the outlet pipe, driving the tool to work. Multiple connection holes 12 are provided on the plane of the connecting flange 11 for installation and fixing. The connecting flange 11 is bolted to other components, such as cylinders and control elements, through the connection holes 12 on the plane, achieving integration of the valve seat and the pneumatic system, ensuring the stability and sealing of the overall structure.

[0030] Reference Figure 1 and Figure 2The valve body 1 is located in the middle of the valve seat. The valve body 1 is rectangular in shape and has a mounting hole 2 in its center. The inner surface of the mounting hole 2 has a high degree of smoothness to meet assembly requirements and improve sealing performance. Gas flows through the mounting hole 2 in the middle of the valve body to the outlet end. Due to the high smoothness of the inner surface of the mounting hole, airflow resistance is reduced and sealing performance is improved, preventing gas leakage. An exhaust port 3 is located on one side of the valve body 1. The exhaust port 3 is used to regulate gas pressure. When the gas pressure in the system exceeds a set threshold, excess gas is discharged through the exhaust port 3 on one side of the valve body, automatically regulating the gas pressure to prevent damage to the equipment due to excessive pressure and ensuring stable system operation.

[0031] Working principle: The external air source is connected through the air inlet sealing thread 5 on the outside of the air inlet pipe 4, and enters the valve body 1 through the air inlet port 6 on the inside of the air inlet pipe 4. It then flows to the outlet end through the central mounting hole 2. When the system air pressure is too high, the gas is discharged through the exhaust port 3 to regulate the air pressure. Finally, the gas flows out from the outlet port 10 on the inside of the outlet pipe 8, and is connected to a pneumatic tool through the outlet sealing thread 9 on the outside of the outlet pipe 8 to drive its operation. The fixing thread 13 on the inside of the fixed platform 7 fixes the valve seat to the bracket, and the top connecting flange 11 is bolted to other components through the connecting hole 12 to ensure structural stability and system integration.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
