Description

Cold and hot water multi-branch connection means and cold and hot water piping system using the same {HOT AND COLD WATER MULTIDROP CONNECTING DEVICE AND WATER PIPING SYSTEM THEREBY}

The present invention relates to a cold and hot water multi-branch connecting means and a cold and hot water piping system using the same. More specifically, the connection socket on one side of the connection pipe is drawn out of the soft pipe to the outside and bent and inserted into the cold and hot water multi-branch connector. By inserting the grip pin in front and inserting the grip pin, it provides a rotatable and firmly fixed cold and hot water multi-connector means to improve the work efficiency by reducing the process and difficulty of the work and at the same time as the rotatable connector. Due to this, it prevents the side grip of the grip ring that is caused by the coupling of the soft pipe with the connection socket, and the grip ring is pushed back when disassembly after reassembly for repair due to the fitting pipe and the grip pin. It is possible to prevent ring retraction, and to fit the cold and hot water multi-connector connector by pushing the connector to the end. If the grip ring is not inserted, the operator can visually check the fastening state of the connector as well as the grip pin can be easily removed by a driver or a hand. The cold / hot water multi-branch connector has guide holes formed at both sides. As the projections formed on the back are guided along the guide grooves of the wall-mounted faucet, they can be slidably moved to enable the worker to easily work through the narrow opening in which the inner cover is installed. Reduced quantity improves the vertical compressive strength of the wall, reduces cost by reducing the total number of parts and reduces the working time, and simplifies the pipe connection in the wall-mounted faucet, which provides high space utilization and two or more faucets in the household. Multi-branch to compensate for sudden changes in flow rate and absorb water hammer during simultaneous use It relates to a cold and hot water piping system to be piped.

In general, when building or expanding a residential space such as a house, apartment, officetel, or hotel, cold and hot water soft pipes introduced from the outside are led to a distributor installed in a sink, a built-in cabinet, a dressing room, and the like. It is sent to each user's demand such as bathroom, boiler room, utility room, laundry room, and auxiliary kitchen to use cold and hot water.

Here, looking at the cold and hot water pipes transferred from the distributor to each demand destination, the outer surface is a double pipe structure in which the soft pipes for the hot and cold water flow paths are inserted into the inside of the curved protective corrugated pipe (Java tube-shaped soft pipe, Corrugated duct), floor, living room, kitchen floor Passing through to the toilet, bathroom, laundry room, and utility room, the connection pipe is bound from each faucet installed at each user's demand, and the hot and cold water pipes are installed in bathtubs, sinks and toilets to supply cold and hot water.

As shown in FIG. 1 disclosed by the present applicant, the cold and hot water pipes introduced to one side using a wall-mounted faucet having a hollow in the center and open to the front side of the faucet are supplied to the receiving place in front of the faucet and branched to the other side. Piping schemes for delivering cold and hot water are now widely used.

In addition, as disclosed by the applicant, in the wall-mounted faucet configured by adding a loop pipe (LOOP PIPE) to compensate for the sudden flow shortage that can occur when using at the same time in two or more faucet and to prevent water hammer phenomenon The pipe connection state is as shown in FIG.

As shown in FIG. 1 to FIG. 2, the conventional pipe connection method is widely used pipe connector 100 of synthetic resin material (PB, PPR, PPC, PE-RT, etc.), the pipe connector 100 The male bracket is formed at both ends and is connected to the female bracket, but the O-ring 232, the washer 233, and the grip ring 234 are sequentially inserted into the male bracket, and the soft tube 4 is strongly inserted from the outside. When the ring 234 opens and stops, the grip ring 234 bites and the O-ring 232 is firmly coupled to prevent leakage.

However, the size of the conventional synthetic resin material pipe connector 100 is a structure in which the contractor is screwed and detached by turning the outer peripheral surface of the arm bracket 235 by hand, if the size of the arm bracket 235 is too small, manual operation is impossible. Since the size of the wall-mounted faucet should be larger than a predetermined size, there was a problem that the size larger than a certain size.

In addition, when the loop pipe (6) is connected, as shown in Figure 2, the pipe connection state is arranged in a complex front and rear double pipe structure has a problem that all the front pipe should be separated for the maintenance of the rear pipe.

In addition, during maintenance after installation, the opening 7a of the inner cover 7 attached before the retaining wall installation is narrower than the opening 2a of the wall recessed faucet 2 so that the space where the user can work by hand is narrower. The repair in the pipe connection state as shown in Figure 1 and Figure 2 has been a problem that is very cumbersome work that takes a lot of effort and time.

In addition, the pipe connector 100 of the synthetic resin material is pushed to push the flexible pipe (4) from the left and right, a considerable length must be inserted into the pipe connector 100 does not cause leakage, but by holding the left and right sides by pushing both hands in a narrow space coupled Not only is it very difficult to make it, it is not possible to check whether the water is properly combined before seeing the inflow of water was a problem that occurs very frequently.

In addition, the pipe connector 100 of the synthetic resin material is separated from the female bracket 235 and the O-ring 232, the washer 233 and the grip ring 234 by the end of the male bracket 231 when the recombination When the retraction occurs once, the retraction occurs once the grip ring 234 makes a scratch mark that penetrates the outer circumferential surface of the soft pipe 4 as much as the retraction length, so that fine leakage occurs, it cannot be advanced again. The male and female brackets are combined to prevent leakage when the end of the soft pipe is cut as much as the retraction occurs.If there is a possibility that the contractor does not detect the retreat, there is a possibility of leaks, and frequent cutting Due to the shortening of the length of the flexible pipe is also frequently occurs when the entire occurrence of the need for improvement.

In addition, when the flexible pipe introduced into the inside of the wall-mounted faucet box is coupled with the connection socket, the coupling angle is different, and when the soft tube is coupled at a predetermined angle, the grip ring 234 in the connection socket is folded and bent. One-grip phenomenon, which presses only one side of the flexible pipe 4, is the cause of water leakage, and there is no sufficient grip, so that the connection socket and the soft pipe are damaged due to water pressure and water hammering during long time use. There was a problem that the phenomenon of separation occurs.

The present invention is to be solved to solve the conventional problems as described above, the connection socket on one side of the connecting pipe is pulled out after the soft pipe to the outside and the other side of the bent insertion portion is fitted in front of the cold and hot water multi-branch connector It provides a rotatable and firmly fixed hot and cold water multi-branch connection means by inserting the grip pin, which reduces the process and difficulty of the work, improving work efficiency, and at the same time, the flexible pipe is connected by the rotatably connected connector. Prevents the grip grip of the grip ring caused by the coupling with the socket and prevents the grip ring retraction caused by the grip ring being pushed backward when disassembly after disassembly for repair due to the fitting pipe and the grip pin. The grip ring cannot be inserted unless the fitting is pushed all the way into the cold and hot water diverter end. Oh, the operator can visually check the fastening state of the connector as well as the grip pin can be easily removed by a driver or a hand. The cold / hot water multi-branch connector has guide holes formed on both sides and a protrusion formed on the back wall. As it is guided along the guide groove of the buried faucet, it is slidable and can be easily operated by the worker through the narrow opening with the inner cover, thereby reducing the size and quantity of the wall buried faucet required for generations.
