Abstract

본 발명은 밸브의 편접촉시의 밸브에 걸리는 응력 측정법에 관한 것이다.The present invention relates to a stress measuring method applied to the valve at the time of single contact of the valve.

일반적으로 밸브는 1m/s이하의 속도로 밸브 시트에 시팅하게 되는데 이때 실린더 헤드 또는 밸브 시트의 뒤틀림이 발생할 수도 있는데 이때에 밸브의 결함이 발생할 수 있기 때문에 새로운 밸브를 설계 제작함에 있어서는 편접촉시의 응력 분포를 면밀히 측정하여 최적의 밸브를 제작할 수 있도록 간단한 밸브의 응력 측정법을 제공하려는 것이다.In general, the valve is seated on the valve seat at a speed of 1 m / s or less. At this time, the cylinder head or the valve seat may be distorted. In this case, the valve may be defective. The aim is to provide a simple method for measuring stresses in valves so that the stress distribution can be measured closely to create the optimum valve.

그 측정법에 있어서 본문에 상술한 바와같이 양 도로게(1)(2)를 고정설치하여 피아노선(3)을 걸은우단에는 가속도계가 부착된 매스(7)를 달고 좌단에는 스트레인 게이지(8)가 부착된 밸브(6)를 달아 매고 밸브 시트(4) 일측에 볼(9)을 박은 다음 매스(7)을 오렸다가 낙하시켜 시팅 속도와 스트레인 값을 측정함을 특징으로 하는 밸브 시팅(Seating)시(時)에 편접촉이 발생할때 밸브에 걸리는 응력 측정법.In the measuring method, as described above in the main text, both road cradles (1) and (2) are fixed to the right end of the piano wire (3), and a mass gauge (7) with an accelerometer is attached to the left end. A valve seating characterized in that the valve 6 is attached, the ball 9 is driven to one side of the valve seat 4, and the mass 7 is raised and dropped to measure the seating speed and the strain value. A method of measuring the stress on a valve when one-sided contact occurs at time.
