Description

정압기의 차단밸브 분해 및 조립용 리프터{lifter for disjointing and assemblage cutoff valve of constant pressure apparatus}Lifter for disjointing and assemblage cutoff valve of constant pressure apparatus}

본 고안은 정압기의 차단밸브 분해 및 조립용 리프터에 관한 것으로서, 특히 이동이 간편하고 중량의 차단밸브를 간편하게 분해 및 조립시킬 수 있도록 한 정압기의 차단밸브 분해 및 조립용 리프터에 관한 것이다.The present invention relates to a lifter for disassembling and assembling a shutoff valve of a pressure regulator, and more particularly, to a lifter for disassembling and assembling a shutoff valve of a constant pressure regulator, which allows easy movement and easy disassembly and assembly of a heavy shutoff valve.

정압기는 가스의 공급압력을 고압에서 중압으로, 또한 중압에서 저압으로 용도에 맞추어 감압하여 공급하는 기능을 갖는다.The constant pressure regulator has a function of reducing and supplying a gas supply pressure from a high pressure to a medium pressure and from a medium pressure to a low pressure according to the application.

정압기의 종들 중 파이롯트(pilot) 제어방식의 정압기는 2차측의 미세한 압력을 감지하여 다이어프램에 구동압력을 증폭시켜서 공급시키는 특징으로 가지고 있다. Among the types of constant pressure regulators, the pilot control type constant pressure regulator is characterized by sensing the minute pressure on the secondary side and amplifying the driving pressure to supply the diaphragm.

이 파이롯트식 정압기는 출구압력이 비교적 안정된 형태로 공급되는 우수한 특징이 있으며, 대량 수용처 및 지구 정압기 등에 주로 사용된다. 또한, 비슷한 크기의 직동식 정압기보다 대용량이 요구되는 유량제어 범위가 양호한 정압기이다.This pilot type pressure regulator has the excellent characteristic that the outlet pressure is supplied in a relatively stable form, and is mainly used for mass storage and earth pressure regulator. In addition, it is a constant pressure regulator having a good flow control range in which a larger capacity is required than a similarly sized direct pressure regulator.

이러한 정압기에는 긴급차단장치(Slam Shut Off Valve)가 설치되어 있다.Such a pressure regulator is provided with a Slam Shut Off Valve.

정압기의 고장(밸브 씨이트의 파손, 이물질의 밸브 씨이트 부착 등)에 의하 여 1차측의 가스가 2차측에 유입하여 2차측의 압력이 상승하면 연소불량, 가스메타의 파손 등 후단기기들의 파손으로 이어질 뿐만 아니라 후단의 저압배관에 중압이 가해질 경우 상당한 위험을 초래할 수가 있기 때문에 이들의 사고를 미연에 방지하기 위하여 긴급차단밸브(SSV)가 설치되며, 조정기 후단의 압력을 항상 감시하여 허용압력 이상이 되면 가스의 흐름을 차단하는 장치이다. If the gas on the primary side flows into the secondary side due to the failure of the constant pressure valve (damage of the valve sheet, adhesion of the foreign matter valve sheet, etc.) and the pressure on the secondary side rises, damage to the downstream equipment such as combustion failure, gas meter breakage, etc. In addition to this, a low pressure pipe at the rear end can cause considerable risk, so an emergency shut-off valve (SSV) is installed to prevent these accidents in advance. If this is the device to block the flow of gas.

이러한 긴급차단밸브의 정비시에는 정압기 본체로부터 분해하여야 하는데, 통상은 두 개의 파이프를 긴급차단밸브의 플랜지에 걸치고, 4명의 작업자가 파이프의 양단부를 파지하여 긴급차단밸브를 정압기본체로부터 분리시키고 있다.In the maintenance of such an emergency shutoff valve, it is necessary to disassemble it from the constant pressure main body. Usually, two pipes are mounted on the flange of the emergency shutoff valve, and four workers separate the emergency shutoff valve from the static pressure main body by holding both ends of the pipe.

그러나 이와 같은 작업은 작업인력을 많이 필요로 할 뿐만 아니라 안전사고의 위험이 있고, 작업시간의 과다소요로 분해 및 조립의 작업성이 저하되는 문제점이 있다.However, such a work requires not only a large number of workers but also a risk of a safety accident, and the workability of disassembly and assembly is degraded due to excessive demand for working time.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 종래의 긴급차단밸브를 간편하게 정압기 본체로부터 분리 또는 조립할 수 있도록 한 정압기의 차단밸브 분해조립용 리프터를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a lift valve for disassembling and assembly of the shutoff valve of the pressure regulator so that the conventional emergency shutoff valve can be easily separated or assembled from the regulator body.

상기 목적을 달성하는 본 고안은 정압기본체의 긴급차단밸브를 분해 또는 조립시에 긴급차단밸브를 지지할 수 있도록 한 정압기의 차단밸브 분해조립용 리프터에 있어서,The present invention to achieve the above object is in the lift valve disassembly assembly lifter of the pressure regulator to be able to support the emergency shut-off valve when disassembling or assembling the emergency shut-off valve of the constant pressure main body,

저면에 복수의 캐스터가 마련된 베이스와, 상기 베이스에 고정되는 리프트잭과, 상기 리프트잭의 상단에 고정되어 리프트잭의 작동에 따라 승강되는 하부판과, 상기 하부판에 하단이 고정되는 복수의 받침지지대와, 상기 받침지지대의 상단에 고정되며 상기 긴급차단밸브의 플랜지가 안착되는 상부판을 구비하며, 상기 상부판은 상기 차단밸브의 몸체가 진입되는 진입구가 형성된 것을 특징으로 한다.A base provided with a plurality of casters on a bottom surface, a lift jack fixed to the base, a lower plate fixed to an upper end of the lift jack and being elevated in accordance with the operation of the lift jack, a plurality of support supports having a lower end fixed to the lower plate, and And an upper plate fixed to an upper end of the supporting support and on which a flange of the emergency shutoff valve is seated, wherein the upper plate is formed with an entry port through which the body of the shutoff valve enters.
