Description

Joint pipe with opening and closing structure of branch pipe {THE PIPE JOINT WITH VALVE OF DIVERGENCE PIPE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint pipe applied to a water purifier, a softener, a bidet, and the like to change the direction of a fluid passage or branch into a plurality. More specifically, the branch pipe is configured to be perpendicular to a straight main pipe. This invention relates to a structure in which an on / off valve for controlling the flow of fluid is installed in a branch pipe of a T-shaped joint pipe so that ease of valve application, precision of fluid control operation, and convenience of handling can be provided.

Normally, a joint pipe is a device used to join a pipe, and there are various types according to the type and size of the pipe, and elbows connected at right angles to the joint fastened by using a screw ), Tee connected in T type, 90 ° Y connected in Y type, cross connected in cross shape, return bend connected in U type, etc. (socket and spigot joint) is used. Where the pipe diameter is large, flanged joints are used.

In addition, valves are installed in the pipelines or in containers to control the flow rate and pressure of fluids. This known cock, a kind of valve, is used to rapidly block or change the flow of fluid by the rotation of a sliding surface that prevents the flow of gas.

Meanwhile, in the water purifier or water softener, a joint pipe 10 having a branch pipe is used to transfer water treated by introducing raw water to a next process or a plurality of uses, and also among the connection pipes connected to the joint pipe 10. The connection pipe 11 of the line in which the selective fluid supply is required is provided with an on / off valve 12 to selectively control the fluid movement.

However, in order to install the on-off valve 12 in the connecting pipe 11, it is necessary to install a separate valve unit directly in the middle of the connecting pipe 11, so that it is cumbersome to purchase the joint pipe and the valve unit separately. In addition, a separate pre-processing process and an assembly process are required for the connection pipe for installation of the on-off valve, which requires a lot of time and manpower to install the valve, and precisely maintains the sealing of the joint portion. In many cases, leakage occurs due to difficulty, and when the connection pipe is made of a flexible material, the connection pipe is caused to flow when the valve is opened and closed, so that the joints of the joints are loosened. I'm doing it.

The present invention has been made in order to solve the problems caused by the existing configuration as described above, the object of the present invention is to ensure the ease of valve application and the precision of fluid control operation, and the convenience of handling,

In order to achieve the above object, the present invention is to install an on-off valve for controlling the flow of fluid on the branch pipe of the T-shaped joint pipe constituting the branch pipe perpendicular to the straight main pipe (main pipe),

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

※ Explanation of code about main part of drawing ※

1: T-shaped joint pipe 2: Host

2A: Inlet 2B: Outlet

3: branch pipe 3A: passage

4: Operation guide 5: On-off valve

5A: Block 5B: Connecting rod

5C: Knob

A passage 3A formed at right angles to a straight main pipe 2 having an inlet port 2A through which the fluid is introduced and an outlet port 2B through which the fluid is discharged, and interconnected with the inside of the main pipe 2 is formed. In the well-known T-shaped joint pipe 1 comprised by the branch pipe 3 provided;

An operation guideway 4 formed in the main pipe 2 in a state extending in a straight line from the passage 3A of the branch pipe 3 and crossing at a right angle with the passage of the inlet 2A and the outlet 2B; ;

A blocking body 5A which is slidably installed in the operation guide 4 to selectively open and close the passage 3A of the branch pipe 3, and the blocking body 5A through a connecting rod 5B. It is configured to include an on-off valve (5) consisting of a knob (5C) is formed integrally connected to and is exposed to linear movement to the outside of the main pipe (2) to control the operation of the blocking body (5A). .

Referring to the operation of the present invention configured as described above are as follows.

3 is a cross-sectional view showing a state of opening the passage of the branch pipe (3), the knob (5C) of the on-off valve (5) is pulled out and the blocking body (5A) is retracted so that the inlet (2A) and outlet ( The connection passage of 2B) is completely out of the passages of the main pipe 2 and the branch pipe 3 so that the connection path of the branch pipe 3 can be connected to the passage 3A of the branch pipe 3.

Therefore, the fluid flowing from the inlet 2A of the main pipe 2 can be transported and discharged to the outlet 2B as well as connected to the branch pipe 3 through the passage 3A of the open branch pipe 3. It can be transported to a predetermined destination through a connecting pipe.

On the other hand, Figure 4 is a cross-sectional view showing a state of closing the branch pipe (3) passage (3A),

The knob 5C of the on-off valve 5 is pressed so that the blocking body 5A enters the inside of the passage 3A of the branch pipe 3 through the connection passage between the inlet 2A and the outlet 2B. As the diameter of the connecting rod 5B is smaller than the inner diameter of the operation guide 4 as the closed state, the inlet port 2A and the outlet port 2B of the main pipe 2 are still open, but the branch pipe The passage 3A of (3) is in a state blocked with the passage of the main pipe 2 by the blocking body 5A.

Therefore, the fluid flowing from the inlet 2A of the main pipe 2 can be transported and discharged to the outlet 2B, but cannot pass through the passage 3A of the closed branch pipe 3 to the branch pipe 3. No fluid can be supplied to the line to which it is connected.

The blocking body 5A applied to the on-off valve 5 is preferably made of a material capable of maintaining excellent durability and sealing property in contact with the inner surface of the operation guide 4 and is not limited to a specific material.

On the other hand, the blocking body 5A is required to be tightly coupled in the operation guide 4 so that appropriate friction is applied, because the position of the blocking body 5A is not applied artificially by applying a force to the knob 5C from the outside. In order to maintain the stop state in the on-off valve (5) is to prevent the flow of the endless flow or impede the failure of the device flow.

The present invention is installed by applying the opening and closing valve (5) directly to the branch pipe (3) of the T-shaped joint pipe, as in the conventional work to solve the trouble of preparing and applying each member individually, easy to apply the valve And since the valve structure is applied to the fitting pipe itself having durability and rigidity, the precision of the opening and closing operation can be secured.

In the present invention as described above, since the valve structure and the fitting pipe are composed of a single body, separate pre-processing is required for the connection pipe for installation of the on-off valve, since the inconvenience of having to purchase the valve unit separately as in the conventional case is excluded. There is no workability is improved and it is easy to maintain the sealing of the joint joint precisely, there is an effect that can improve the reliability of the product through leakage prevention.
