The present invention relates to a sprinkler system, and more specifically, to a sprinkler system which can be assembled without welding. To this end, the sprinkler system according to the present invention comprises: a main pipe through which fluid is supplied from an externa source; a first branch pipe for branching the fluid supplied through the main pipe; a second branch pipe for branching the fluid supplied through the first branch pipe so that said fluid is supplied to a sprinkler; and a detachable first coupler for interconnecting the main pipe, the first branch pipe, and the second branch pipe.

Sprinkler system

The present invention relates to a coupling assembly for branching a pipe, and more specifically to a coupling assembly for branching a pipe, which can reduce assembly man-hours, has a simplified configuration, thus enabling a reduction in construction costs, and can effectively prevent the leakage of branched fluid even when the diameter of a branch hole formed in an inlet pipe is increased in order to increase a flow rate inside a branch pipe for supplying fluid to a sprinkler.

Coupling assembly for branching pipe

Disclosed is a coupling assembly for pipe connection, which, even when connecting pipes having different diameters to each other, can reduce the resistance against a fluid flowing inside the pipes, can be installed in a state where couplers are temporarily assembled using fastening members, and is not deformed during the fastening process and thus can also be stably fixed after the fastening process.

Coupling assembly for pipe connection

A coupling assembly for connecting pipes includes two or more couplers which are arranged facing each other in order to connect pipes continuously disposed in the axial direction, and the pipes are connected to each other in a state in which coupling members are temporarily assembled to the plurality of couplers. The couplers have catch parts which are inserted into coupling grooves formed in the pipes and have inner diameters corresponding to the outer diameters of the coupling grooves. Interference preventing grooves are formed in both sides of the catch parts and prevent interference between the pipes and the catch parts to allow the outer circumferential surfaces of the pipes to pass through between the temporarily assembled couplers.

Coupling assembly for connecting pipes, and manufacturing method therefor

The present invention relates to a coupling assembly for pipe branching and, more specifically, to a coupling assembly for pipe branching, which: can reduce assembly man-hours; has a simplified structure and thus can reduce construction costs; and can effectively prevent leakage of a branch fluid even when the diameter of a branch hole formed through an inflow pipe is increased in order to enable the increase in the internal flow rate of a branch pipe through which a fluid is supplied to a sprinkler.

Coupling assembly for pipe branching

A coupling assembly for pipe connection and a method of manufacturing the same are disclosed. The coupling assembly for pipe connection is installable while a coupler is preassembled using a fastening member and is not deformed even in a fastening process so as to be stably fixed even after fastening. The coupling assembly is configured so that two or more couplers are disposed to face each other to connect pipes consecutively disposed in an axial direction and the pipes are connected while a fastening member is preassembled to the plurality of couplers, each of the couplers includes a locking part that is inserted into a fastening groove formed in the pipe, a portion of the locking part is inserted into the fastening groove, and the remaining portion of the locking part is disposed outside the fastening groove.

Coupling assembly for pipe connection and method of manufacturing the same

A check valve having a reverse-direction fluid supply function capable of supplying a fluid in a reverse direction by opening a fluid passage formed in a central shaft of a disk configured to open or close a flow path. The valve includes a valve main body into which a fluid is introduced, a shaft installed in the valve main body and configured to move forward toward an inside of the valve main body or backward toward an outside of the valve main body, a disk disposed in the valve main body and configured to open or close the valve main body, and a spring interposed between the disk and an inner surface of the valve main body. The disk opens the valve main body due to fluid pressure and blocks the same when fluid pressure is removed by movement of the shaft or by an elastic reaction force of the spring.
