[0002] During the development of airguns, various types of airgun valve body designs have emerged. Some of these designs generate sound pulses through a secondary valve control cavity, have a large flow area and a main valve core with a specific structure. Due to the design of the split welding structure, the existing integrated multifunctional valve body of airguns has certain deficiencies in integration. The split welding structure means that the valve body is welded from multiple parts. This design method increases the size and weight of the equipment and reduces its portability and flexibility. At the same time, the split structure also increases the complexity of the internal structure of the valve body, making it difficult to achieve the optimal overall performance of the equipment. The cavity of the split welding structure is the main reason for the high difficulty of assembling the equipment structure. During the assembly process, it is necessary to ensure precise docking and sealing between the various parts to ensure the overall performance and reliability of the valve body.
