Description

Technical Field

[0001] The utility model relates to the technical field of boring tools for valve seat holes, in particular to a special boring tool for valve seat holes. Background Art

[0002] The valve seat is the core component of the mud pump, usually made of high-strength, high-hardness alloy steel. It undertakes the important tasks of supporting the valve body and ensuring sealing performance and wear resistance. When the mud pump is working, the valve seat fits tightly with the valve body through its precise matching structure to prevent mud leakage and ensure the normal operation of the pump. The design of the valve seat takes into account the working environment and pressure requirements of the mud pump. After the heat treatment process, it has excellent surface hardness and core toughness. In addition, the valve seat also has good interchangeability and versatility, and is suitable for mud pumps of various specifications and models. Therefore, the performance and quality of the valve seat have an important impact on the working efficiency and service life of the mud pump.

[0003] Existing special boring tools for valve seats are usually designed and manufactured according to valve seats of specific sizes, so their scope of application is relatively limited. When valve seats of different sizes need to be processed, boring tools of different specifications may need to be replaced, which not only increases the complexity of operation, but also may lead to an increase in production costs: Since special boring tools are highly targeted and relatively flexible, when faced with valve seats of different sizes or shapes, special boring tools may not be able to process them effectively, thereby limiting their scope of application. At the same time, it is necessary to pay attention to the collection of iron chips generated during processing to avoid waste of resources. Utility Model Content
