Abstract:
본 발명은 고압용 유체이송관 부품 조립장치에 관한 것이다. 본 발명에 따른 고압용 유체이소관 부품 조립장치는 유체가 흐르는 유체이송관에 장착된 밸브에 결합되는 중공형의 하우징, 하우징의 내부에 왕복이동 가능하게 삽입되며, 하단부에 유체이송관에 조립될 부품이 분리가능하게 결합되는 로드, 로드의 외주면과 하우징의 내주면 사이에 개재되어, 하우징 내부의 공간을 상호 밀폐되어 있는 제1공간부 및 제2공간부의 2개의 공간으로 분리하는 제1실링부재, 부품을 로드로부터 분리가능하게 하는 결합시키는 착탈수단 및 유체이송관으로부터 배출되는 유체에 의하여 로드에 상방향으로 가해지는 압력에 대응하여, 제1공간부에 유체를 주입하여 로드에 대하여 하방향으로 압력을 인가하는 가압수단을 구비하는데 특징이 있다.
Abstract:
PURPOSE: Reflecting unit and pipe for measuring flow velocity/flow rate and an ultrasonic flowmeter having the same are provided to accurately measure the flow velocity of fluid by preventing the distribution or flow of the fluid from becoming distorted. CONSTITUTION: A reflecting unit and pipe for measuring flow velocity/flow rate comprises a flow pipe, a flow hole and a reflective surface. The flow hole is formed in the length direction of the flow pipe. The flow hole moves fluid and is a through hole. The reflective surface is formed to slope to the length direction of the slow pipe. The reflective surface reflects ultrasonic wave. The reflective surface is formed to slope at an angle of 45° with respect to the length direction of the flow pipe.
Abstract:
PURPOSE: A protective case for a watertight pressure transmitter for protecting surge and a watertight pressure transmitter module for protecting the surge comprising the same are provided to prevent the surge from becoming transferred to a pressure transmitter from a water pipe and to enable the pressure to be accurately measured. CONSTITUTION: A protective case for a watertight pressure transmitter for protecting surge comprises a first housing(10), an isolating bushing(20) and a second housing(30). The first housing is connected to a target of which pressure is measured. The first housing comprises an inlet hole into which the fluid flows. The isolating bushing is connected to the first housing. The isolating bushing comprises a penetration hole communicated with the inlet hole. To the isolating bushing, the connection part(201) of a pressure transmitter(200) is connected. The second housing is connected to the first housing so that the pressure transmitter is arranged between the first housing and the second housing.
