버터플라이밸브 충격압력 시험장치 개발

Generally valves has been used since a long time ago and controls the pressure that expressed as a characteristic of the physics in the fluid and the speed, which means the fluid flow. The ball and gate valve have been used in the case of power plant, chemical plant, shipbuilding area and so on. However a butterfly valve has been used as a large size valve, over 400 mm inside diameter, because of the installation area and weight problems. The valve test has been doing to have a reliability of products in domestic and abroad but many of the small-medium sized business have difficulties to do the durability test because of the man power and cost before coming out the products in the market. Therefore, they need to have the test equipment to be reproduced with the operating conditions in the laboratory same as a real operating conditions at the fields. Previous test equipment did the valve durability test applying impulse pressures about small-medium sized valves but there are limitations in the case of the large sized valves to supply the flow to the valves to apply the impulse pressure and to increase the pressure into the test system. So this study has been doing the development of test equipment to reproduce the impulse pressure using two storage tanks and two hydraulic pumps.
