Design Proposal for Hydraulic Valve: Causes and Countermeasures for Seat Leaks from the Design Stage

Leak issues in hydraulic valve relief valves, along with examples of successful countermeasures from the design stage.

Our company, Nakaniwa Seisakusho (Aichi Prefecture), is a parts manufacturer specializing in precision machining, primarily focusing on hydraulic equipment. Here, we introduce a customer case based on an order placed with us. < Nakaniwa Seisakusho - Hydraulic Valve Leak Improvement Case > ■ Background of Proposal: There were no issues during the prototype phase, but when it moved to mass production, problems such as pressure drops occurred, leading to losses due to parts reassembly during assembly. ■ Proposal Points: The main cause of the pressure drop is leakage at the seat area, but significant improvements can be made through design changes. 1. Roundness and Roughness of the Seat Area └ By changing the position of the sleeve's seat area to remain within about twice the inner diameter of the sleeve from the entrance, the difficulty of machining is reduced, and accuracy is improved. └ Indications for "pin angle" and "perpendicularity" are not very meaningful, as they only increase difficulty and costs. 2. Implementation of the Fitting Process └ When heat treating the poppet, the sleeve should be left in its raw state, and the "fitting" process will be illustrated. ■ Customer Feedback The pass rate has significantly improved, allowing for production according to plan. With the reduction in machining difficulty, the number of capable vendors has increased, contributing to cost reduction. *Please feel free to consult us.
