PF 정압기 SSV 설치 및 분해용 지그{DISASSEMBLING AND ASSEMBLING JIG FOR PE SSV GAS PRESSURE REGULATOR}PF pressure regulator SSV installation and disassembly jig {DISASSEMBLING AND ASSEMBLING JIG FOR PE SSV GAS PRESSURE REGULATOR}

본 고안은 PE(Pietro Forentine) 정압기 SSV(Slam Shut Valve)를 정비하기 위해 유압으로 상하 이송시킬 수 있도록 하는 PF 정압기 SSV 설치 및 분해용 지그에 관한 것이다.The present invention relates to a jig for installing and disassembling a Pietro Forentine (PE) static pressure SSV (Slam Shut Valve) that allows hydraulic pressure to move it up and down for maintenance.

천연가스 공급시설에서 수요자측(발전소 또는 도시가스회사)으로 공급되기 전 설치되어 있는 정압기는 가스의 공급압력을 고압에서 중압으로, 또한 중압에서 저압으로 용도에 맞추어 감압하여 공급하는 기능을 갖는다.The pressure regulator installed in the natural gas supply facility before supplying it to the consumer (power plant or city gas company) has the function of supplying the gas by reducing the supply pressure from high pressure to medium pressure and from medium pressure to low pressure according to the purpose.

현재 공급관리소에 설치 운영되는 정압기는 주배관의 고압가스를 발전소 및 도시가스사의 요구압력에 맞게 일정하게 공급하기 위해 설치된 설비이며, 정기점검 주기는 2년에 1회 이상이다.The pressure regulator currently installed and operated in the supply management office is a facility installed to constantly supply high-pressure gas from the main pipe according to the required pressure of power plants and city gas companies, and the regular inspection period is more than once every two years.

일반적으로 정압기 본체의 정비해야 될 부분이 높은 위치에 있어서, 부품을 분해 조립하기 위해서는 발판과 호이스트를 이용하여 부품을 하나하나 옮겨야 하는 불편함과, 그로 인한 정비시간 지연, 부품 낙하에 의한 부품 파손 및 신체 손상 등 위험성과 조립 후 조립상태 점검을 위한 동작상태 점검의 어려움, 정비 시 부품의 중량물로 인한 세척의 불편함이 있어왔다.In general, the parts to be maintained in the main body of the pressure regulator are located at a high position, and in order to disassemble and assemble the parts, it is inconvenient to move the parts one by one using a footrest and a hoist, and the resulting delay in maintenance time, damage to parts due to falling parts, and There have been risks such as damage to the body, difficulty in checking the operation state to check the assembly state after assembly, and inconvenience in cleaning due to the heavy weight of parts during maintenance.

정압기라는 것은 가스를 일정하게 고정된 압력으로 바꾸어 내보내는 장치를 말하는 것이다.A constant pressure device refers to a device that converts gas into a constant fixed pressure and discharges it.
