Abstract

The present invention relates to a height-adjustable, non-stop water valve. Specifically, it relates to a non-stop water valve with a lowered bonnet that houses the valve disc. When a conventional non-stop water valve is installed close to the ground, part of the structure protrudes outside the ground, which is a hassle that requires tilting the structure during installation. This height-adjustable, non-stop water valve has an improved bonnet that houses the valve disc that is lower than conventional valves.

Description

Technical Field

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

[0002] Furthermore, it relates to a non-stop water valve having a structure capable of adjusting the height in a bonnet for accommodating a valve disk. Conventionally, when constructing a non-stop water valve when the depth on the pipe is close to the ground, since a part of the structure protrudes outside the ground, in order to overcome the trouble such as constructing with the structure tilted, it relates to a height-adjustable non-stop water valve in which the height of the bonnet for accommodating the valve disk has been improved to a lower height than conventional.

Background Art

[0003] Normally, water control valves are installed at intervals of 1 km to 3 km in the water supply pipe. When replacing a part of the water supply pipe, it is necessary to close the front and rear water control valves to block the water flow for water stoppage.

[0004] However, even though the replacement section of the water supply pipe is a partial section, since all the front and rear water control valves with a long distance interval are closed, water stoppage must be performed so that water does not flow into a plurality of water supply pipes branched from the section between the front and rear water control valves to the usage destinations such as each household. Eventually, a wide water stoppage area is formed, and inconvenience to residents' lives and damage to livelihoods are inevitable.

[0005] In addition, due to problems such as poor water blocking and malfunction due to aging of the water control valve, the water stoppage section increases, and the replacement work of the water supply pipe takes a long time, there is a problem that the increase in water stoppage time and the inconvenience of residents' lives are aggravated.

[0006] In order to solve such problems, a method of replacing a pipe such as a water supply pipe using a non-stop water valve construction method is used.

[0007] As an example of the above-described non-stop water valve construction method, refer to the attached FIGS. 4 and 5.

[0008] First, a valve body 110, which is a component of a non-stop water supply valve, is attached to the outer circumference of the water supply pipe 100 to be replaced. The valve body 110 is composed of a pair of hemispherical bodies that can surround the outer circumference of the water supply pipe, and in particular, an opening 114 is formed on the upper surface of the upper hemispherical body 112, and an auxiliary valve 116 that can open and close the opening is installed inside the upper hemispherical body.

[0009] Next, a rotating device (not shown) for rotating the valve body 110 is attached to the front and rear positions of the valve body 110 of the water supply pipe 100. Then, a drilling device (not shown) is attached to the opening 114 of the upper hemispherical body 112 of the valve body 110 in a way that keeps it watertight.

[0010] At this time, the auxiliary valve 116 inside the upper hemispherical body 112 is operated to open it, allowing the end mill cutter of the drilling device to be in close contact with the outer surface of the water supply pipe 100.

[0011] Next, when the valve body 110 is rotated angularly along the arc direction of the water supply pipe 100 using the rotating device, the drilling device assembled on the upper hemispherical body 112 of the valve body 110 also rotates angularly by the same angle.

[0012] Therefore, when the drilling device rotates at an angle, the end mill cutter of the drilling device operates to process a drilled hole 102 on the outer surface of the water supply pipe 100, thereby forming an arc-shaped drilled hole 102 on the outer surface of the water supply pipe 100.

[0013] Next, to prevent water leakage from the perforated hole 102 of the water supply pipe 100, the auxiliary valve 116 inside the upper hemispherical body 112 is operated to the closed position, and then the perforating device is removed.

[0014] Next, a bonnet 130, in which the valve disc 400 is housed so as to be vertically movable, is assembled in a watertight manner into the opening 114 of the upper hemispherical body 112 of the valve body 110, and then the auxiliary valve is operated to the open position again.

[0015] Next, the stem 132 exposed on the upper part of the bonnet 130 is rotated to lower the valve disc 400, which is screw-connected to the stem inside the bonnet 130, until it is completely inserted into the water supply pipe 100 through the perforated hole 102 drilled in the outer surface of the water supply pipe 100.

[0016] Finally, by removing the aforementioned rotating device and other ancillary components, the assembly and installation of the non-stop water supply valve for replacement into the water supply pipe is completed.

[0017] At this time, the rubber valve seat forming the outer body of the valve disc comes into close contact with the inner surface of the water supply pipe, thereby blocking the flow of water and preventing water from entering.

[0018] However, in the case of the aforementioned non-stop water supply valve, if the depth of the pipe is adjacent to the ground, it protrudes from the ground during installation, which necessitates the troublesome process of tilting the pipe during installation.

[0019] This is a problem that arises when the height of the pipe is adjacent to the ground, because, in conventional non-stop water valves, an auxiliary valve is built into the top plate for installation using a drilling machine and for maintenance of the valve disc, and the valve disc is located above the auxiliary valve. However, due to the limitations of this mechanical structure, there is a limit to how low the height of the non-stop water valve can be lowered.

[0020] Therefore, in order to overcome the aforementioned problems, the applicant has focused on a non-stop water valve that includes a bonnet that houses the valve disc in an improved structure. [Overview of the project] [Problems that the invention aims to solve]

[0021] The object of the present invention relates to a structure for reducing the height of a non-stop valve.

[0039] Furthermore, the bonnet (20) is

[0040] The bonnet (20) further includes a mounting section (22) in which a low-height insert (30) is placed inside a hole (21),

[0041] The mounting portion (22) is

[0042] The low-height insert (30) includes a crescent-shaped plate structure to prevent obstruction of the movement of the valve disc (10) when the stem (50) that penetrates the low-height insert (30) extends downward and connects to the valve disc (10), and the side walls are raised from the plate structure to be integrally connected to the inside of the extended upper surface of the bonnet (20).

[0043] Furthermore, the intermediate cover (40) includes a through hole on one side.

[0057] The terms and words used in this specification and in the claims should not be interpreted in a manner limited to their ordinary or encyclopedic meanings, but rather in a manner and concept consistent with the technical idea of ​​the present invention, based on the principle that an inventor may appropriately define the concept of a term in order to best describe his own invention.

[0058] Therefore, the embodiments and configurations shown in the drawings described herein are merely the most preferred embodiments of the present invention and do not represent the entire technical concept of the present invention. Thus, it should be understood that various equivalents and modifications may exist at the time of filing.

[0059] Before proceeding with the following explanation with reference to the drawings, matters unnecessary for illustrating the gist of the present invention, namely known configurations that can be clearly added by a person skilled in the art, will not be shown or specifically described.

[0060] This invention relates to a height-adjustable, non-stop water supply valve.

[0061] Furthermore, regarding a continuous water supply valve having a height-adjustable structure for the bonnet housing the valve disc, conventionally, when installing a continuous water supply valve when the depth of the pipe is close to the ground, a part of the structure protrudes outside the ground, making it troublesome to install the structure by tilting it. To overcome this, the height of the bonnet housing the valve disc has been improved to a lower height compared to conventional designs, thus relating to a height-adjustable continuous water supply valve.

[0062] The height-adjustable, non-stop water supply valve according to the present invention will be explained with reference to the attached drawings.

[0063] Figure 1 shows the bonnet housing the valve disc of the height-adjustable non-stop water supply valve according to the present invention, before and after insertion; Figure 2 shows an example of the installation of the height-adjustable non-stop water supply valve according to the present invention, before and after insertion; and Figure 3 shows the bonnet of the height-adjustable non-stop water supply valve according to the present invention disassembled.

[0064] The height-adjustable non-stop water supply valve according to the present invention includes all the structures of a conventional non-stop water supply valve. However, only the structure of the bonnet housing the valve disc is improved.

[0065] The standards for all structures of such non-stop water valves shall refer, for example, to the "Method for forming perforations in pipelines by efficient rotary drilling" described in the applicant's Korean Registered Patent No. 10-1906108.

[0066] The bonnet structure of the height-adjustable non-stop water valve according to the present invention, as shown in the attached Figures 3 and 4, comprises: a valve disc 10; a bonnet 20 that houses the valve disc 10 and is coupled to a housing to allow the valve disc 10 to be pulled out; a low-height insert 30 configured to be inserted into the bonnet 20 from above to allow the height of the bonnet to be adjusted; an intermediate cover 40 that finishes the upper side of the bonnet 20 into which the low-height insert 30 is inserted and has a hole of a predetermined diameter formed on one side; a stem cover 60 that is inserted into and placed on the low-height insert 30; a stem 50 coupled to one side of the stem cover 60 and passing through the intermediate cover 40, the low-height insert 30 and the bonnet 20 downwards to connect to the valve disc 10; and a fixed cover 70 coupled to the upper side of the intermediate cover 40 and configured to cover the lower structure up to the stem cover 60, but having a hole on one side so that one end of the stem is exposed.

[0067] Furthermore, 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 the low-height insert 30 is formed on the other side of this upper surface so that the low-height insert 30 can be inserted into it.

[0068] Furthermore, the bonnet 20 includes a mounting section 22 inside the hole 21 for mounting the low-height insert 30 in an inserted state.

[0069] At this time, the mounting portion 22 described above is configured to have its side walls raised from a crescent-shaped plate structure and to be integrally connected to the inside of the expanded upper surface of the bonnet 20.

[0070] The reason why the lower surface of the mounting portion 22 described above is configured in a semi-circular shape is to allow the stem 50, which penetrates the mounted low-height insert 30, to extend downward and connect to the valve disc 10, while not obstructing the movement of the valve disc 10.

[0071] In this case, the crescent-shaped plate configuration consists of at least two pieces, enabling the secure placement of the low-height insert 30.

[0072] Furthermore, the low-height insert 30 includes a through-hole 32 that penetrates in the height direction, and a recessed mounting groove 31 is formed on one side of the upper surface of the low-height insert 30.

[0073] The stem cover 60 is placed in such a mounting groove 31 and secured with bolts or the like.

[0074] In addition to the structure described above, the lower end of the low-height insert 30 is bent and expanded, and the hole 21 in the bonnet 20 is formed to correspond to the diameter of the expanded lower end of the low-height insert 30.

[0075] The diameter of the through-hole in the intermediate cover 40 is formed to correspond to the diameter of the unexpanded area of ​​the low-height insert 30.

[0076] Furthermore, multiple layers of grooves are formed along the circumferential direction on the inner wall surface of the through-hole in the intermediate cover 40, and double-row O-rings are bonded to them to improve the airtightness between the intermediate cover 40 and the low-height insert 30, thereby improving watertightness.

[0077] 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, with its expanded end positioned in the hole 21 of the bonnet 20.

[0078] Subsequently, by pushing and inserting the low-height insert 30 at the construction site, it is possible to prevent the upper part of the valve from being exposed above the ground, as shown in Figure 2.

[0079] Therefore, unnecessary slope work can be avoided, leading to improved work efficiency.

[0080] As described above, an example of the installation of the height-adjustable non-stop water supply valve according to the present invention will be explained using Figure 6 and subsequent figures.

[0081] First, install the upper and lower plates of the water-continuous valve as in the conventional manner, as shown in Figure 6 of the attached document.

[0082] Next, as shown in the attached Figure 7, the non-stop valve drilling machine and end ring guide are installed and the pipe is drilled. After drilling, the auxiliary valve is closed, and then the end ring guide and drilling machine are separated, as shown in Figure 8.

[0083] Subsequently, the height-adjustable bonnet according to the present invention is installed in the housing (upper plate and lower plate) (Figure 9), the auxiliary valve is opened to create dynamic pressure on the bonnet, the low-height insert 30 is pushed down, and the fixing cover 70 is attached and secured (Figure 10).

[0084] Subsequently, as shown in Figure 11, the valve disc 10 is lowered after the fixed cover is joined to perform the water supply work without interruption, and as shown in Figures 12 and 13, the valve disc 10 is raised to complete the work.

[0085] On the other hand, in another embodiment, the height of the bonnet can be designed to be adjustable in order to achieve the height-adjustable, non-stop water supply valve of the present invention.

[0086] This height adjustment may be achieved by inserting the low-height insert 30 described above, or by adjusting the height of the bonnet 20, as will be described later, as shown in Figures 14 to 19.

[0087] First, Figures 14 to 16 show one embodiment using a rectangular bonnet. Figures 17 to 19, which will be described later, show one embodiment using a cylindrical bonnet.

[0088] However, the shape of such a bonnet is not limited to a square or cylindrical shape, and may be in various forms having a configuration within the scope of the rights of the present invention.

[0089] Figure 14 shows a height-adjustable, non-stop water supply valve according to another embodiment of the present invention.

[0090] Furthermore, Figure 15 shows the external configuration of the height-adjustable non-stop water supply valve before and after insertion according to Figure 14, and Figure 16 shows the internal configuration of the height-adjustable non-stop water supply valve before and after insertion according to Figure 14.

[0091] The bonnet according to this embodiment is constructed by cutting in an antenna shape, with one being a fixed bonnet 202 that forms the lower side and is fixedly coupled to the housing, and the other being a height-adjustable bonnet 201 which has a size and shape that is inserted into the exterior of the fixed bonnet 202 and has a bolt coupling structure on one side for bolt coupling with the fixed bonnet 202.

[0092] At this time, the outer surface of the fixed bonnet 202 includes multiple airtight members (O-rings, packing, etc.) so that when the height-adjustable bonnet 201 is inserted into the fixed bonnet 202 and pressurized, it can ultimately have the height after insertion shown in Figures 15 and 16.

[0093] Afterward, the fixed bonnet 202 and the height-adjustable bonnet 201 are joined and secured using bolts.

[0094] Such a bonnet may have a rectangular shape as illustrated above, but it may also have a cylindrical shape as shown in attached Figure 17.

[0095] Figure 17 shows a height-adjustable, non-stop water supply valve according to yet another embodiment of the present invention.

[0096] Furthermore, Figure 18 shows the external configuration of the height-adjustable non-stop water supply valve before and after insertion according to Figure 17, and Figure 19 shows the internal configuration of the height-adjustable non-stop water supply valve before and after insertion according to Figure 17.

[0097] However, in this embodiment where the bonnet is cylindrical, the shape of the valve disc 10 may also be slightly modified. For example, the upper valve disc 101 is configured in a cylindrical shape on the lower side of the region where the stem 50 is attached, but it is made to be shaped so that it slopes downwards and converges to a single point. The lower valve disc 102 is then integrally extended to one side of this lower configuration, thereby enabling it to perform the role of a conventional valve disc.

[0098] The above explanation, using the drawings, describes only the main aspects of the present invention. Various designs are possible within its technical scope, and therefore, it is clear that the present invention is not limited to the configuration shown in the drawings.
