Description

Height-adjustable non-return valve

[0001] The present invention relates to a height-adjustable valve.

[0002] In detail, the present invention relates to a non-stop valve having a structure capable of adjusting the height of a bonnet that accommodates a valve disc. In order to overcome the inconvenience of having to tilt the structure when constructing a non-stop valve because a part of the structure protrudes outward from the ground when the depth of the conventional pipe is close to the ground, the present invention relates to a height-adjustable non-stop valve in which the height of the bonnet that accommodates the valve disc is improved to be lower than that of the conventional one.

[0003] Typically, sluice valves are installed at intervals of 1 to 3 km in water pipes, and when replacing a section of water pipe, the sluice valves before and after must be closed to block the flow of water.

[0004] However, since all the water valves before and after the water pipe replacement section are closed at a long distance, water will not flow from the section between the water valves before and after the water pipe to each household and other users, which will inevitably lead to a water cutoff, which will eventually lead to a wide water cutoff area, causing inconvenience to residents and damage to businesses.

[0005] In addition, there are problems such as increased water outage intervals due to poor water supply and malfunction caused by aging of the water valve, or excessively long time required for water pipe replacement work, which increases the water outage time and increases inconvenience to residents.

[0006] To solve these problems, a method of replacing pipes such as water pipes using a non-return valve construction method is being used.

[0007]

[0008] As an example of the above-described non-return valve construction method, refer to FIG. 4 and FIG. 5 of the attached drawings.

[0009] First, a valve body (110), which is a component of a non-return valve, is mounted on the outer diameter of a water pipe (100) for replacement. The valve body (110) is composed of a pair of hemispherical bodies capable of surrounding the outer diameter of the water pipe, and in particular, an opening (114) is formed on the upper surface of the upper hemispherical body (112), and an auxiliary valve (116) capable of opening and closing the opening is installed inside the upper hemispherical body.

[0010] Next, a rotating device (not shown) capable of rotating the valve body (110) is installed at the front and rear positions of the valve body (110) of the water pipe (100), and then a perforation device (not shown) is installed in the opening (114) of the upper hemispherical body (112) of the valve body (110) so as to maintain watertightness.

[0011] At this time, the auxiliary valve (116) in the upper hemispherical body (112) is operated to the open state so that the end mill cutter of the perforation device can be brought into close contact with the outer diameter surface of the water pipe (100).

[0012] Next, when the valve body (110) is rotated along the arc direction of the water pipe (100) using the above-mentioned rotating device, the perforation device assembled to the upper hemispherical body (112) of the valve body (110) also rotates at the same angle.

[0013] Accordingly, when the perforating device rotates, the end mill cutter of the perforating device operates to process a perforation hole (102) on the outer diameter surface of the water pipe (100), thereby forming an arc-shaped perforation hole (102) on the outer diameter surface of the water pipe (100).

[0014] Next, to prevent water leakage through the perforation hole (102) of the water pipe (100), the auxiliary valve (116) in the upper hemispherical body (112) is closed, and then the perforation device is removed.

[0015] Next, a bonnet (130) having a valve disc (400) movably built into the opening (114) of the upper hemispherical body (112) of the valve body (110) is assembled in a way that it can maintain watertightness, and then the auxiliary valve is operated to the open state again.

[0016] Next, by rotating the stem (132) exposed to the upper portion of the bonnet (130), the valve disc (400) connected to the stem and screws inside the bonnet (130) is lowered until it passes through the perforation hole (102) perforated on the outer surface of the water pipe (100) and is completely inserted into the inside of the water pipe (100).

[0017] Finally, by removing the auxiliary parts such as the above-mentioned rotating device, the assembly of the water valve for the water pipe for replacement is completed.

[0018] At this time, the rubber valve seat forming the outer body of the valve disc is pressed against the inner diameter surface of the water pipe, thereby creating an index that blocks the flow of water.

[0019] [Correction under Rule 91 17.10.2023] However, in the above-mentioned non-return valve, if the depth of the pipe is close to the ground, there is the inconvenience of having to incline during construction because the non-return valve protrudes into the ground during construction.

[0020] [Correction pursuant to Rule 91, October 17, 2023][Deleted]

[0021] This is because, looking at the conventional non-stop valve, an auxiliary valve is built into the upper plate for construction using a perforator and maintenance of the valve disc, and the valve disc is located above the auxiliary valve. Due to the limitations of this mechanical structure, there is a limit to lowering the height of the non-stop valve, and this is a problem that occurs when the height of the pipe is close to the ground.

[0022]

[0023] Accordingly, the applicant has conceived a non-return valve including a bonnet that accommodates a valve disc in an improved structure so as to overcome the above-described problems.

[0024] The purpose of the present invention is to provide a structure for lowering the height of a non-return valve, and to overcome the inconvenience of having to tilt the structure when constructing a non-return valve because a part of the structure protrudes outward from the ground when the depth of the pipe is close to the ground, thereby providing a height-adjustable non-return valve in which the height of the bonnet that accommodates the valve disc is improved to be lower than that of the conventional one.

[0025] In order to achieve the above-described purpose, the height-adjustable non-stop valve according to the present invention is a height-adjustable non-stop valve including a bonnet structure that is maintained in a lowered state by pressurization at a construction site.

[0026] As an example, it is characterized by including a bonnet structure that is maintained in a lowered state by pressing a low-height insert (30) at a construction site and closing it with a fixed cover (70).

[0027]

[0030] A bonnet (20) that accommodates the above valve discs (10) and is coupled to the housing to extract the valve disc (10);

[0031] A low-height insert (30) configured to be inserted into the upper side of the bonnet (20) so as to allow the height of the bonnet to be adjusted;

[0032] An intermediate cover (40) that finishes the upper side of the bonnet (20) in which the above low-height insert (30) is inserted, and has a hole having a predetermined diameter formed on one side;

[0033] A stem cover (60) that is inserted and installed into the above low-height insert (30);

[0034] A stem (50) that is connected to one side of the above stem cover (60) and penetrates downward through the middle cover (40), low-height insert (30) and bonnet (20) to be connected to the valve disc (10);

[0035] It is characterized by including a fixed cover (70) configured to cover the lower structure up to the stem cover (60) by being connected to the upper side of the intermediate cover (40), but configured to include a hole on one side so that one end of the stem is exposed.

[0036]

[0037] At this time, the low-height insert (30)

[0038] It is configured by bending the lower end to expand,

[0039] It includes a through hole (32) extending in the height direction of the low-height insert (30),

[0040] It is characterized in that a concave mounting groove (31) is formed on one side of the upper surface of the above low-height insert (30).

[0041]

[0042] In addition, the above bonnet (20)

[0043] Its upper surface has a circular, extended structure,

[0044] It is characterized in that a hole (21) having a diameter corresponding to the expanded area of ​​the low-height insert (30) is formed on the other side of the upper surface.

[0045]

[0046] In addition, the above bonnet (20)

[0047] It further includes a mounting portion (22) that allows a low-height insert (30) to be mounted in a position inserted into the hole (21) of the above bonnet (20).

[0048] The above-mentioned fixing part (22) is,

[0049] When the stem (50) penetrating the low-height insert (30) extends downward and is coupled to the valve disc (10), the valve disc (10) is characterized in that it includes a crescent-shaped plate structure so as not to impede the movement of the valve disc (10), and a side wall is erected from the plate structure and is configured to be integrally coupled to the inside of the extended upper surface of the bonnet (20).

[0050]

[0051] In addition, the above intermediate cover (40) includes a through hole on one side,

[0052] The through hole of the above intermediate cover (40) is characterized by having a size corresponding to the unexpanded diameter of the low-height insert (30).

[0053]

[0054] In addition, it is characterized in that an O-ring is positioned between the through hole of the intermediate cover (40) and the low-height insert (30).

[0055]

[0056] In the bonnet structure described above,

[0057] When the above intermediate cover (40) is connected to the bonnet (20), the low-height insert (30) is fixed by the intermediate cover (40) and the expanded end is positioned in the hole (21) of the bonnet (20).

[0058] Afterwards, by pressing and inserting a low-height insert (30) at the construction site,

[0059] It is characterized by being able to prevent the upper part of the valve from being exposed above the ground during construction.

[0061] As another example, the bonnet (20) is configured in a double configuration so that the length can be adjusted in the form of an antenna, and is configured as a height-adjustable bonnet (201) and a fixed bonnet (202).

[0062] It is characterized in that the height is adjusted by inserting the above height-adjustable bonnet (201) into the fixed bonnet (202).

[0063]

[0064] In addition, it is characterized by further including a bolt fixing structure so that the height-adjustable bonnet (201) is fixed with a bolt after being inserted into the fixed bonnet (202).

[0065]

[0066] In addition, a number of sealing means are provided on one side of the fixed bonnet (202), which seals the space between it and the height-adjustable bonnet (201).

[0067]

[0068] In addition, the bonnet (20) is characterized by having one shape selected from among a square, a cylinder, and a polygon.

[0069] According to the height-adjustable non-return valve according to the present invention described above, when constructing a non-return valve in a case where the depth of the existing pipe is close to the ground, it has the advantage of overcoming the inconvenience of having to construct the structure by tilting it, because a part of the structure protrudes outward from the ground.

[0083] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0084]

[0085] Hereinafter, before explaining with reference to the drawings, it is to be noted that matters that are not necessary to reveal the gist of the present invention, that is, known configurations that can be obviously added by a person skilled in the art with ordinary knowledge, are not illustrated or specifically described.

[0086]

[0087] The present invention relates to a height-adjustable valve.

[0088] In detail, the present invention relates to a non-stop valve having a structure capable of adjusting the height of a bonnet that accommodates a valve disc. In order to overcome the inconvenience of having to tilt the structure when constructing a non-stop valve because a part of the structure protrudes outward from the ground when the depth of the conventional pipe is close to the ground, the present invention relates to a height-adjustable non-stop valve in which the height of the bonnet that accommodates the valve disc is improved to be lower than that of the conventional one.

[0089]

[0090] The height-adjustable valve according to the present invention will be described with reference to the attached drawings.

[0091] Fig. 1 shows a bonnet for accommodating a valve disc of a height-adjustable non-return valve according to the present invention before and after insertion, Fig. 2 shows an example of installing a height-adjustable non-return valve according to the present invention before and after insertion, and Fig. 3 shows an exploded view of the bonnet of a height-adjustable non-return valve according to the present invention.

[0092]

[0093] The height-adjustable valve according to the present invention includes all structures of conventional valves. However, only the structure of the bonnet housing the valve disc is improved.

[0094] For all structures of these non-return valves, please refer to, for example, the 'Method for forming perforations in a pipeline through efficient rotary perforation' described in the applicant's registered patent No. 10-1906108.

[0095]

[0096] The bonnet structure of the height-adjustable valve according to the present invention according to FIGS. 3 and 4 of the attached drawings comprises: a valve disc (10); a bonnet (20) that accommodates the valve disc (10) and is coupled to a housing to withdraw the valve disc (10); a low-height insert (30) configured to be inserted into the upper side of the bonnet (20) to enable the height of the bonnet to be adjusted; an intermediate cover (40) that closes the upper side of the bonnet (20) into which the low-height insert (30) is inserted and has a hole having a predetermined diameter formed on one side; a stem cover (60) that is inserted into and seated in the low-height insert (30); a stem (50) that is coupled to one side of the stem cover (60) and penetrates downward through the intermediate cover (40), the low-height insert (30), and the bonnet (20) to be coupled to the valve disc (10); It is configured to include a fixed cover (70) that is connected to the upper side of the above intermediate cover (40) and is configured to cover the lower structure up to the stem cover (60), but is configured to include a hole on one side so that one end of the stem is exposed.

[0097]

[0098] In addition, the bonnet (20) has a structure in which one side of its upper surface is expanded in a circular shape, and a hole (21) having a diameter at least larger than that of the low-height insert (30) is formed on the other side of the upper surface so that the low-height insert (30) can be inserted.

[0099] In addition, the bonnet (20) further includes a mounting portion (22) that allows a low-height insert (30) to be mounted in an inserted state inside the hole (21).

[0100] At this time, the above-mentioned fixing member (22) is configured to be integrally connected to the inner side of the extended upper surface of the bonnet (20) by erecting a side wall from a crescent-shaped plate structure.

[0101] Here, the reason why the lower surface of the above-mentioned mounting portion (22) is configured in a crescent shape is to allow the stem (50) penetrating the mounted low-height insert (30) to extend downward and be coupled to the valve disc (10), while not impeding the movement of the valve disc (10).

[0102]

[0103] At this time, the above crescent-shaped plate structure is composed of at least two pieces to ensure the stable placement of the low-height insert (30).

[0104]

[0105] In addition, the low-height insert (30) includes a through hole (32) extending in the height direction, and a concave mounting groove (31) is formed on one side of the upper surface of the low-height insert (30).

[0106] A stem cover (60) is installed in this installation groove (31) and connected with a bolt or the like.

[0107]

[0108] In further detail to the above-described structure, the lower part of the low-height insert (30) is configured to be folded and expanded, and the hole (21) of the bonnet (20) is formed to correspond to the diameter of the lower part of the expanded low-height insert (30).

[0109] The diameter of the through hole of the intermediate cover (40) is formed to correspond to the diameter of the non-expanded area of ​​the low-height insert (30).

[0110] In addition, a plurality of grooves are formed along the circumferential direction on the inner wall surface of the through hole of the intermediate cover (40), and a double-row O-ring is combined to improve the airtightness between the intermediate cover (40) and the low-height insert (30), thereby improving the watertightness.

[0111]

[0112] In this structure, when the intermediate cover (40) is connected to the bonnet (20), the low-height insert (30) is fixed by the intermediate cover (40) and the expanded end is positioned in the hole (21) of the bonnet (20).

[0113] Afterwards, by pressing and inserting a low-height insert (30) at the construction site, the upper part of the valve can be prevented from being exposed from the ground as shown in Fig. 2.

[0114] Therefore, it is possible to improve work efficiency by eliminating the need to perform unnecessary tilting work.

[0115]

[0116] As described above, an example of construction of a height-adjustable valve according to the present invention will be described through Fig. 6 and the following of the attached drawings.

[0117]

[0118] First, as shown in Figure 6 of the attached drawing, the upper and lower plates of the non-return valve are installed as before.

[0119] Next, as shown in Fig. 7 of the attached drawing, a perforation work is performed on the pipe by installing a non-perforating valve perforator and an end ring guide, and as shown in Fig. 8, after perforation, the auxiliary valve is closed and the end ring guide and the perforator are separated.

[0120]

[0121] Afterwards, the height-adjustable bonnet according to the present invention is installed in the housing (upper and lower plates) (Fig. 9), the auxiliary valve is opened to pressurize the bonnet, the low-height insert (30) is pressed down, and the fixed cover (70) is combined to fix it (Fig. 10).

[0122] Afterwards, as shown in Fig. 11 of the attached drawing, the valve disc (10) is lowered after the fixed cover is combined to perform the non-removable construction, and as shown in Figs. 12 and 13, the valve disc (10) is raised to complete the construction.

[0123]

[0124] Meanwhile, in order to achieve the height-adjustable valve of the present invention as another embodiment, the bonnet may be designed to be height-adjustable.

[0125] This may be to achieve the purpose of height adjustment through the interpolation of the low-height insert (30) described above, or may be to achieve the purpose through height adjustment of the bonnet (20) as described later, which is shown in FIGS. 14 to 19 of the attached drawings.

[0126]

[0127] First, FIGS. 14 to 16 of the attached drawings illustrate an embodiment according to a square-shaped bonnet. In addition, FIGS. 17 to 19 described below illustrate an embodiment according to a cylindrical-shaped bonnet.

[0128] However, the shape of the bonnet is not limited to a square or cylinder, and may have various shapes as long as it has a configuration within the scope of the present invention.

[0129]

[0130] Fig. 14 illustrates a height-adjustable valve according to another embodiment of the present invention.

[0131] In addition, Fig. 15 shows the external configuration before / after interpolation of the height-adjustable non-return valve according to Fig. 14, and Fig. 16 shows the internal configuration before / after interpolation of the height-adjustable non-return valve according to Fig. 14.

[0132]

[0133] The bonnet according to the embodiment is configured by being cut in an antenna form, one of which is a fixed bonnet (202) that forms the lower side and is fixedly connected to the housing, and the other one has a size and shape that is inserted into the exterior of the fixed bonnet (202), and includes a height-adjustable bonnet (201) having a bolt-joining structure for bolt-joining with the fixed bonnet (202) on one side.

[0134] At this time, the outer surface of the fixed bonnet (202) includes a number of sealing materials (O-rings, packing, etc.), so that the height-adjustable bonnet (201) is inserted into the fixed bonnet (202) and pushed in by applying pressure, thereby finally having the height after insertion as shown in FIGS. 15 and 16.

[0135] Afterwards, the fixed bonnet (202) and the height-adjustable bonnet (201) are combined and fixed using bolts.

[0136]

[0137] Such a bonnet may have a square shape as in the example described above, but may also have a cylindrical shape as in Fig. 17 of the attached drawing.

[0138]

[0139] Fig. 17 illustrates a height-adjustable valve according to another embodiment of the present invention.

[0140] In addition, Fig. 18 shows the external configuration before / after interpolation of the height-adjustable non-return valve according to Fig. 17, and Fig. 19 shows the internal configuration before / after interpolation of the height-adjustable non-return valve according to Fig. 17.

[0141]

[0142] However, in the case of the embodiment in which the bonnet is cylindrical, the shape of the valve disc (10) may also be changed somewhat. For example, the upper valve disc (101) may be configured in a cylindrical shape below the area where the stem (50) is coupled, but may have a shape that slopes downward and converges at one point, and the lower valve disc (102) may be configured to be integrally extended to one side of the lower portion so as to perform the role of a conventional valve disc.

[0143]

[0144] The description using the drawings above only describes the main aspects of the present invention, and it is obvious that the present invention is not limited to the configuration of the drawings, as various designs are possible within the technical scope.
