That is, in general, one side of the header is open to allow fluid to flow in, but the other side is blocked by the blind flange 6 so that the pressure of the header is increased when the flowed in fluid does not flow out.

The blind flange 6 is here coupled with a flange 5 coupled to the end of the header 2 and generally with a gasket 9 interposed therebetween, the coupling being effected by bolts 6 and nuts 5. Will be maintained.

On the other hand, the branch pipes 3 are connected to the side of the header 2, respectively. That is, the fluid may be distributed through the branch tubes or the fluid may flow into the header. In addition, the branch pipes are normally connected to the shut-off valve 4, through which it is possible to selectively distribute the fluid.

In addition, the header is usually installed larger than the diameter of the inlet pipe (1) and branch pipe (3) in order to ensure a smooth distribution.

However, in the conventional header structure 10, a header is formed, and in order to connect the branch pipes to the side surfaces of the headers, holes in the side surfaces of the headers 2 must be welded to the branch pipes 3 so that many processes are required. There was a problem, each branch pipe had to be installed separately because the isolation valve (4) there was a problem of excessive installation space.

2 is a cross-sectional view of a distribution valve according to an embodiment of the present invention, Figure 3 is a side cross-sectional view of the distribution valve according to an embodiment of the present invention.

As shown, the distribution valve 100 according to an embodiment of the present invention comprises a body 110, a valve disk assembly 120, the packing means 190 and the valve seat 130.

The main body 110 has a predetermined space 140 is formed therein, the openings 150, 160, 170, 180 are formed so that the four sides open to the outside so that the fluid can flow in and out.

The valve disc assembly 120 is detachably provided at the upper opening 160 of the main body so that fluid cannot flow in and out through the upper opening of the main body, and a valve seat 130 is provided at the lower side of the main body. . That is, it is possible to block or control the inflow and outflow of fluid to the lower opening 150 of the body by the valve disk assembly and the valve seat.

 Here, the valve seat 130 may be formed integrally with the main body 110, which is preferably manufactured integrally at the time of casting or injection of the main body. Of course, it will be possible to separately insert the valve seat 130 in the lower opening 150 of the body.

However, in consideration of the possibility of leakage, separate assembly process, etc., the valve seat 130 may be manufactured integrally with the main body 110, and the material of the main body may be a metal material. For convenience, the body may be made of a plastic material.

In addition, the valve seat 130 preferably protrudes a predetermined length into the body. Because when air collects in the header, it needs to be removed immediately. Since air collects in the upper part of the header, if the valve seat is protruded close to the upper part in the main body which functions as the header, the air in the header can be easily removed. Because you can.

In addition, the valve seat 130 is characterized in that it has an effect of reducing noise problems or vibration problems caused by the flow of the fluid by securing a certain distance to the straight pipe of the fluid flowing into or out of the lower opening 150 of the body. In addition, it is possible to minimize the length of the valve shaft to be described later to prevent damage to the valve shaft.

It is preferable that the lower opening 150 of the main body further includes a connection means (not shown) to which the branch pipe is connected. That is, when the branch pipe is connected to the lower opening of the main body, a connecting means may be provided to the main body from the beginning so that the branch pipe can be easily connected without additional processing or addition of a device.

The connecting means may be integrally provided with a flange portion on the outer periphery of the lower opening 150 of the main body, and a female or male thread may be formed in the lower opening of the main body so that the pipe may be screwed. In addition, grooves or grooves may be formed on the outer circumference of the lower opening 150 of the main body so as to be a Victorian coupling joint, for example.

A packing unit 190 may be provided around the side surface of the main body to prevent leakage when the main body 110 is connected to another main body. As the packing means 190, an O-ring groove 191 into which an O-ring 192 may be inserted is formed around one side of the main body, and one side of the other main body connected to the main body is processed to a predetermined surface roughness. Flat surfaces can be formed. That is, the flat surface is to prevent the leakage by pressing the O-ring.

In addition, a gasket seat may be formed around the side of the main body to prevent leakage by inserting a gasket into the gasket seat when the main body and the other main body are coupled.

On the other hand, the main body 110 is preferably made of a symmetrical shape. That is, when the main body is side-connected with the other main body and the main bodies are in communication with each other through the side openings 170 and 180, the main body is to be connected to each other even when the other main body rotates a predetermined angle. For example, if the side of the main body is made of a square, it will be possible to connect even when the main body is rotated by an angle of 90 degrees, even in this case, the leakage by the packing means will be prevented.

In other words, when connecting the plurality of distribution valves it is possible to easily change the direction of the lower opening 150 of the distribution valve in the up, down, left and right directions. Therefore, the advantage that can be changed by adjusting only the connection angle of the distribution valve direction of the branch pipe to be branched through this.

The valve disc assembly 120 may include a valve disc 115, a valve shaft 116, a packing gland 118, and an o-ring 117.

Here, the valve disc 115 is provided to block the flow of fluid through the valve seat 130, or to adjust the flow cross-sectional area. In addition, the shape of the valve disk 115 can be changed according to the purpose of the valve.

One end of the valve shaft 116 is connected to an upper portion of the valve disc 115, and the other end of the valve shaft 116 protrudes out of the upper opening 160 of the main body 110. Accordingly, when the valve shaft 116 is moved up and down, the valve disk 115 is moved up and down inside the body.

On the other hand, the upper opening 160 of the main body is blocked by the packing gland 118 to prevent the flow of fluid, the center of the packing gland is provided with a through hole so that the valve shaft 116 can pass through. . In addition, an O-ring groove in which the O-ring 117 is inserted is formed at a predetermined position of the through-hole, and the O-ring is prevented from leaking through the through-hole.

In addition, a packing gland cover (not shown) may be further included to cover the upper opening of the main body so that the packing gland does not fall out of the main body.

As described above, the above-described valve disk assembly 120 may be detachably provided at the upper opening 160 of the main body 110. Accordingly, the configuration of the valve disk assembly may be changed to a valve disk assembly of a general globe valve or a control valve and coupled to the upper opening 160 of the main body according to the present invention.

That is, in addition to the function of the shutoff valve, in some cases, the function of adjusting the pressure of the fluid flowing into the branch pipe or controlling the flow rate of the fluid flowing into the branch pipe may be performed.

Hereinafter, a header structure 200 constructed using a distribution valve 100 according to an embodiment of the present invention will be described with reference to FIG. 4, and the function of the header structure will be described.

Figure 4 is a schematic diagram showing a header structure configured using a distribution valve according to an embodiment of the present invention.

As shown in Figure 4, the header structure 200 of the present invention is composed of a distribution valve 100, the coupling means.

As described above, the distribution valve 100 is a valve through which fluid is introduced through both side openings 170 and 180, and fluid may be branched through the lower opening 150. In addition, the upper opening 160 of the valve is detachably provided with a valve disc assembly 120 that can block the inflow of fluid into the branch pipe or adjust the pressure or flow rate.

On the other hand, in order to configure the header structure 200, the distribution valve must be at least two side coupling. 4 illustrates an example in which four distribution valves are connected. The distribution valve coupling may be connected to prevent leakage by packing means, for example, a gasket 190.

As an example of coupling means necessary to maintain coupling of the distribution valve 100 in the header structure 200, flanges 220 and 230, stud bolts 230, nuts 235, and the like are illustrated in FIG. 4.

Referring to the coupling means in detail, first the inlet pipe 210 and the flange 220 of the left side is coupled. In addition, the distribution valve 100 is sequentially coupled from the right side of the flange, and the blind flange 250 is coupled to the right side of the last distribution valve.

That is, the distribution valves 100 coupled between the two flanges 220 and 250 are inserted. When the stud bolts 230 are inserted into the two flanges, and the nut 235 is tightened from the outside of the flanges, the distribution valve 100 is inserted. ) And the flanges are maintained to form a header structure 200.

Of course, a packing means for preventing leakage should also be provided between the flange and the distribution valve.

Then, the branch 240 pipe is connected to the lower opening of each of the distribution valves coupled. As described above, since the distribution valves are symmetrical shapes that may be coupled to each other even when rotated at a predetermined angle, the direction of the branch pipe may be directed upward or downward as shown, and may also be directed toward the front or the rear.

On the other hand, the coupling means is not limited to those using a flange and stud bolts, as shown. For example, connecting means may be further provided on both sides of the distribution valve so as to be combined with pipes or other distribution valves, respectively, to form the coupling means. Such connecting means may be a screw joint or a victorious coupling joint. This will be possible.

The function of the header structure 200 shown in FIG. 4 will be described below.

First, the fluid is introduced into each of the distribution valve 100 through the flange 220 from the inlet pipe 210. That is, since the blind flange 250 has no pipe connection hole, the fluid does not flow out through the blind flange, so that the whole of the flange 220 and the blind flange 250 functions as one header.

Meanwhile, the fluid introduced into the header flows out through branch pipes 240 connected to each distribution valve 100. Of course, fluid may be introduced through the branch pipe. Here, the valve disc assembly is operated to selectively block the flow of fluid through the branch pipes (240). Matters related to such a fluid inflow and shutoff and control of flow rate or pressure are as described above.

That is, the number of branch pipes 240 is determined according to the number of distribution valves 100, and when expansion of branch pipes is required, this purpose can be achieved by combining one more distribution valve in the structure.

Hereinafter, with reference to Figure 5 will be described in detail the configuration of the distribution valve according to another embodiment of the present invention.

5 is a side cross-sectional view of a distribution valve according to another embodiment of the present invention.

Since another embodiment of the present invention basically has the same configuration as the above-described embodiment of the present invention, only the differences in distribution valves according to another embodiment of the present invention will be described.

As shown in FIG. 5, the distribution valve 300 according to another embodiment of the present invention has a thickness portion of the main body different from one embodiment, and flesh is added to a predetermined portion, and a through hole through which a stud bolt passes through the portion ( The cavity 380 is formed with the air 370.

The through hole 370 is formed so as to pass through a thickness portion between the inner 340 and the outside of the main body 310 and penetrate through the other side edge of the main body 310.

Preferably, at least four through-holes 370 are provided on a side surface of the main body in a radially symmetrical form. Each of the through-holes has a rectangular cross-sectional side surface at a side portion of the main body, and into the main body. As it penetrates, it is preferable to have a circular cross section.

Because the stud bolt generally has a circular cross section, when the stud bolt is inserted into the through hole 370, the stud bolt has a rectangular cross section, and the first stud bolt is easily inserted. In addition, as the cross-section becomes circular, that is, the cross-section of the stud bolt toward the inside of the through-hole, each of the distribution valves that are automatically coupled are aligned with each other.

That is, it is easy to insert the stud bolt by the change in the cross-sectional shape of the through-hole 370, and also has the advantage that the alignment of the plurality of distribution valves are coupled automatically to achieve the header structure easily It becomes possible.

On the other hand, the cavity 380 may be formed on the part of the thickness of the thickness of the thickness between the outside and the inside of the main body, the cavity is to have air in the interior, such air performs a very good heat insulating material function do.

In general, when the pipe is installed, the heat insulating material is covered with the outside of the pipe for heat insulation or cold insulation, and the installation of the heat insulating material for heat insulation is not easy for valves such as headers other than general pipes. Therefore, it is possible to directly perform the insulation function of the distribution valve itself through the cavity.

On the other hand, through the cavity, it is possible to obtain an effect that can cope with a dimensional change during injection, casting, or cooling after molding to form the outer shape of the main body.

Finally, a header structure constructed using a distribution valve according to another embodiment of the present invention is as follows.

The header structure constructed using the distribution valve according to another embodiment of the present invention is basically the same as the header structure constructed using the distribution valve according to the embodiment according to the present invention as shown in FIG. 4.

However, the former allows the stud bolt to be coupled across the outside of the body, while the latter allows the stud bolt to be coupled across the side between the outside and the inside of the body. That is, in the latter case, the through hole through which the stud bolt penetrates is formed in the main body.

In addition, the function of the header structure configured using the distribution valve according to another embodiment of the present invention is the same as the function of the header structure of the distribution valve described above.

Embodiment of the present invention as described above is configured to help the understanding of the present invention is not limited only to the above-described embodiment, various modifications are possible within the scope without departing from the technical spirit of the present invention.

The following effects can be obtained through the distribution valve and the header structure using the same according to the present invention.

First, the header structure can be more easily installed because a work process such as drilling a hole or welding is not required.

Second, since the separate shutoff valve is not installed in the branch pipe, the installation space of the header structure can be reduced.

Third, the new branch pipe can be more easily installed in the existing header structure.
