The present invention relates to a branch valve used to provide a water supply line to a home appliance using water by branching the line in the raw water supply line. More specifically, all parts except the sealing materials used for airtight construction are made of plastic material, which simplifies the processing process to improve productivity, and provides economical, practical and eco-friendly opening and closing of the branch passage. It is to provide a branch valve with a valve function to enable flow control.

Products such as water purifiers and bidets, which are spreading in recent years, must use tap water for their functions, so it is essential to divert the pipes from indoor water pipes during installation. On the other hand, unlike the plumbing branch used to build a new building, water supply equipment applied to household equipment should be installed by separating the connection part of the existing pipe, and the leakage of the connecting part after construction should be ensured that no leakage occurs. Of course, it is desirable to have a structural requirement that the direction of the branch outlet can be easily adjusted so that the hose is not bent or twisted.

A general example of a conventional water supply device having such basic requirements is shown in FIG. 1, and its features are as follows.

Most parts of the conventional water supply equipment are made of a metal material, and the exterior is chrome plated to prevent corrosion. The thread 71 is machined on the upper outer circumferential surface of the body 70 so that the connection port 20 of the outer conduit is connected. The coupling nut is configured to rotate independently of the body, and a thread is provided on the inner circumferential surface of the coupling nut to be screwed to the thread at the end of the raw water pipe 10. A branch flow passage 72 protrudes and is provided at the center of the body, and a separate hose connector 74 is screwed to a thread processed in the branch flow passage.

However, since most of the parts constituting the water supply branch are manufactured by cutting metal materials such as brass, the price of the materials is expensive, and the processing must be performed at various stages, so there is a problem of productivity and the resulting cost burden. In order to prevent corrosion, it has to be accompanied by chromium plating which is regulated as environmentally harmful substances. In addition, if there is no function to selectively open and close the branch flow path, in case of a failure of the product supplied through the branch flow path, the valve in the raw water supply line must be locked. There was also the inconvenience of having to singularly.

The present invention has been conceived to solve the above problems, taking advantage of the advantages of the plastic material to maximize the formation of complex individual structures in one injection molding, to prevent bending or bending to compensate for the rigidity of the plastic material It is an object of the present invention to provide a branch valve with improved practicality by reinforcing the supporting structure and by incorporating a valve unit to individually open or close the branch flow path or control the flow rate.

Still another object of the present invention is to provide an environmentally friendly branch valve because the plastic itself is a corrosion resistant material and thus does not require a separate chrome plating process.

Another object of the present invention is to provide a branch valve which can be used by combining the branch valve of the present invention in any direction in parallel or in parallel when it is desired to expand the number of branch flow paths.

Branch valve of the present invention for achieving the above object,

In the lower part of the body formed of plastic material, it has a latching engagement means consisting of a latching coupling groove and a latching support jaw concentrically. At the same time it is characterized in that the coupling nut is coupled to the elastic coupling and independent of the body.

In addition, a second outlet passage connected to the second external passage is provided at the center of the body, and a valve unit coupling portion is integrally formed with the body at an opposite surface opposite to the second outlet passage. The insert is characterized in that the screw and the body.

In addition, the valve unit is composed of a piston, a cylinder, a valve cover, a valve handle, a piston sealing member and a flow path blocking member, and the outer peripheral surface of the piston is partially provided with a thread, and the piston engages with the thread of the cylinder lower portion to rotate the piston. The flow rate control unit provided at the end of the piston while changing the inside of the cylinder to change the flow path cross-sectional area of the inlet of the second outlet is characterized in that for controlling the flow rate supplied to the second external conduit through the second outlet.

In addition, the lower end of the body is provided with a sealing member support jaw and the sealing member detachment prevention jaw to prevent the separation of the sealing member generated in the process of assembly, packaging, transportation, construction, repair, and the like.

In addition, by integrally forming a pair of handles opposed to each other on the outer peripheral surface of the connection nut, it is characterized in that the operation is possible without using a separate tool when connecting to the external conduit.

Another feature of the present invention is to implement a component configuration excluding the chrome plating process, which is a representative process for discharging environmentally harmful substances by using the body, the connection nut and the valve unit as a corrosion-resistant plastic.

Another feature of the present invention is that the thread of the first outer conduit connection portion of the body, the thread of the second outer conduit connection portion and the thread of the valve unit coupling portion are male threads, and the thread of the connection nut is composed of female threads. In the same way, the branch valves can be connected and used in multiple directions in parallel or in parallel, so as to expand the required branch flow paths, and to control the opening and closing of individual branch flow paths. It is equipped with maximum expandability, such as a water outlet.

 Hereinafter, a branch valve formed of a plastic material having rigidity and elasticity according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
