Description

[0001] APPARATUS FOR RELEASING JOINT OF FLUID PIPE [0002]

The present invention relates to a fluid pipe connection device, and more particularly, to a fluid pipe connection device capable of reliably releasing an insertion installation such as a valve or a flow meter connected to a fluid pipe.

Generally, city gas or constant water is supplied through a fluid pipe. This fluid pipe facility cuts and arranges the fluid pipe to the required length from the supply site to the demand site, and is equipped with a reducer, a tee Tee, and an elbow to connect the pipe. If necessary, connect the valve or the flow meter on the fluid pipe.

The rubber packing 400 is inserted between the flange 120 and the connecting flange 120 of the fluid pipe 200 before the fitting 100 is coupled with the bolt nut.

However, between the flanges 120 and 220, the flanges 120 and 220, which are strongly tightened to prevent fluid leakage when bolted to the bolt nut, are tightened together more tightly by the packing 400. [ .

When the flanges 120 and 220 are tightly bonded to each other, if the bolt nut 300 joining the flanges 120 and 220 is loosened for maintenance or replacement of the insertion fitting 100, Or the insertion fitting 100, such as a valve, is not separated by the fitting by the packing. Accordingly, an extension such as the flat head screwdriver 500 must be pushed in between the flanges 120 and 220 to perform additional work such as twisting or forcing it to be forced.

However, in such an additional operation, it is difficult to insert the elongated portion between the narrow flanges. Even if the elongated portion is inserted, when the flange is forcibly forced or twisted, the flange may be bent due to the strong force, In the process, it can damage old steel pipes. If the flange is bent or scratched, there is a problem such that sealing between the flanges is not performed properly at the subsequent reassembly, and if the steel pipe is damaged, it causes a bigger problem.
