Description

[0001] Cross Reference to Related Applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2024-0137128, filed on October 8, 2024, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference. TECHNICAL FIELD

[0003] The present application relates to a valve. BACKGROUND

[0004] A valve can be a device that adjusts fluid flow by opening or closing a flow path through which fluid flows. The valve can be classified into a butterfly valve that adjusts the flow of fluid by installing a rotating shaft of a disc-shaped valve disc and rotating the rotating shaft, and a solenoid valve that opens or closes the valve using magnetic force by winding a wire in a spiral shape and applying power.

[0005] The butterfly valve can be provided in an electrically driven manner, in which case, since a motor and a reducer should be provided together, manufacturing costs can increase. Also, in the solenoid valve, it is difficult to manufacture a valve having a relatively large diameter of a flow path.

[0006] In this regard, there is an increasing demand for a valve that can be manufactured such that the diameter of the flow path is relatively large and the manufacturing cost is relatively low.

[0007] The valve can include a valve body having a flow path formed therein, and a bobbin body including a solenoid, one side of which can be formed in an open shape in the process of forming the flow path in the valve body for manufacturing reasons.

[0008] Therefore, there is an increasing demand for a valve that improves the air tightness and the assemblability between a valve cover covering one side of a valve body and the valve body. SUMMARY

[0047] Referring to Figures 1 to 5 , the valve 100 can be a device for opening / closing a flow path 210 through which a fluid such as hydrogen flows.

[0048] The valve 100 can include a valve body 200 formed so that a fluid flows and forms the flow path 210 including a portion extending in a first direction (D1 or a direction opposite to D1), and a solenoid module 300 installed on the valve body 200 to surround the flow path 210 from the outside of the flow path 210.

[0049] A process of removing a mold from one side D1 of the valve body 200 in the first direction toward the inside of the valve body 200 can be used to form the flow path 210 inside the valve body 200.

[0050] When such a process is performed, one side D1 of the flow path 210 in the first direction can be formed to be open. In order to close one side D1 of the flow path 210 in the first direction, the valve 100 can further include a valve cover 400 installed on the valve body 200.

[0051] The valve body 200 can include an inlet 220 communicating with the flow path 210 to supply fluid to the flow path 210 and an outlet 230 discharging fluid from the flow path 210. The inlet 220 and the outlet 230 can be located at opposite ends of the flow path 210 with respect to the flow direction of the fluid.

[0052] The solenoid module 300 can include an electromagnetic coil 310 installed on the valve body 200 to surround the flow path 210 from the outside of the flow path 210 and a bobbin body 320 formed in a hollow cylindrical shape to surround the electromagnetic coil 310.

[0053] The bobbin body 320 can be disposed outside the valve body 200 and can be formed to surround the electromagnetic coil 310. The electromagnetic coil 310 disposed inside the bobbin body 320 can be sealed.

[0054] Although not separately shown in the drawings, the electromagnetic coil 310 can receive external power through a connector, and thus current can be applied thereto. The bobbin body 320 according to the embodiment of the present application can be integrally formed with the valve body 200.

[0055] The valve cover 400 can include a cover area 410 installed on the valve body 200 to cover one side D1 of the flow path 210 in the first direction and a disc holding area 420 supported by the cover area 410 and disposed inside the flow path 210.

[0056] The valve cover 400 can include a valve disc 500 formed of a magnetic material to open or close the flow path 210 by the electromagnetic coil 310 and rotatably disposed on the flow path 210.

[0057] The cover area 410 and the disc holding area 420 of the valve cover 400 according to the embodiment of the present application can be integrally formed.

[0058] The cover area 410 can be a portion installed on one surface of the valve body 200 on one side D1 in the first direction to cover the flow path 210.

[0059] The disc holding area 420 can be a portion inserted into the flow path 210 from the cover area 410. In other words, the disc holding area 420 can be inserted into the flow path 210 from one side D1 of the flow path 210 in the first direction. The disc holding area 420 can rotatably support the valve disc 500.

[0060] The disc retaining area 420 can be disposed between the cover area 410 and the valve body 200 in the first direction (D1 or a direction opposite to D1).

[0061] In more detail, the valve body 200 can include a first inner surface 211 defining the flow path 210 and disposed radially outside the valve cover 400, and a second inner surface 212 formed on the other side of the first inner surface 211 in the first direction (a direction opposite to D1) and protruding more toward the center of the flow path 210 than the first inner surface 211. In addition, the valve body 200 can include a fixed surface 213 connecting the first inner surface 211 and the second inner surface 212.

[0062] When the disc retaining area 420 is in contact with the fixed surface 213, the position in which the valve cover 400 is inserted into the valve body 200 can be guided. In other words, the disc retaining area 420 can be inserted from one side D1 of the flow path 210 in the first direction to the other side (a direction opposite to D1) in the first direction, and then can be in contact with the fixed surface 213, whereby insertion to the other side (a direction opposite to D1) in the first direction can be prevented.

[0063] The disc retaining area 420 can be disposed between the cover area 410 and the fixed surface 213 of the valve body 200 in the first direction (D1 or a direction opposite to D1), and the disc retaining area 420 can be supported by the cover area 410.

[0064] Due to this structure, the position in which the valve cover 400 is inserted into the valve body 200 can be guided. Thereby, when only the cover area 410 and the valve body 200 are coupled, even without a separate structure, the disc retaining area 420 and the valve disc 500 can be stably supported inside the flow path 210. Accordingly, the structure of the valve 100 can be simplified, thereby reducing the cost and weight of the valve 100.

[0065] The disc retaining area 420 can rotatably support the valve disc 500. The disc retaining area 420 can include a support area 430, a rotation shaft 440, an opening stopper member 450, and a closing stopper area 460.

[0066] The support area 430 can support opposite ends of the rotation shaft 440, and can be in contact with the first inner surface 211 of the valve body 200. The first inner surface 211 can be in contact with the support area 430 outside the flow path 210 in the radial direction to support the support area 430.

[0067] The support area 430 can include a first support area 431 supporting one end of the rotation shaft 440, and a second support area 432 supporting the other end of the rotation shaft 440 and disposed in parallel with the first support area 431.

[0068] The first support area 431 and the second support area 432 can be supported by the first inner surface 211 of the valve body 200 in a radially outward direction. An end of the first support area 431 and the second support area 432 on the other side in the first direction (a direction opposite to D1) can be in contact with the fixed surface 213, and its position can be fixed by the fixed surface 213.

[0069] The rotation shaft 440 can extend in a second direction (D2 or a direction opposite to D2) intersecting the first direction (D1 or a direction opposite to D1), and its opposite end can be supported by the first support area 431 and the second support area 432. The rotation shaft 440 can support the valve disc 500 rotatably.

[0070] The opening stop member 450 can be disposed on the side D1 further than the rotation shaft 440 in the first direction, and can extend in parallel with the rotation shaft 440. That is, the opening stop member 450 can extend in the second direction (D2 or a direction opposite to D2). Opposite ends of the opening stop member 450 can be supported by the first support area 431 and the second support area 432.

[0071] The closing stop area 460 can be connected to the cover area 410, and can be spaced apart from the rotation shaft 440 in a third direction (D3 or a direction opposite to D3). Here, the third direction (D3 or a direction opposite to D3) can be a direction intersecting the first direction (D1 or a direction opposite to D1) and the second direction (D2 or a direction opposite to D2).

[0072] The closing stop area 460 can extend in the first direction (D1 or a direction opposite to D1). An outer peripheral surface of the closing stop area 460 can be in contact with the first inner surface 211 of the valve body 200 from the radially outer side of the flow path 210. An end of the closing stop area 460 in the first direction (D1 or a direction opposite to D1) can be in contact with the fixed surface 213 to prevent the closing stop area 460 from being further inserted to the other side in the first direction (D1 and a direction opposite to D1).

[0073] The closing stop area 460, the first support area 431, and the second support area 432 can be formed to be spaced apart from each other in a circumferential direction when viewed from the side D1 in the first direction. In other words, the closing stop area 460, the first support area 431, and the second support area 432 can extend to the other side in the first direction (a direction opposite to D1) while being spaced apart from each other in the circumferential direction from the cover area 410.

[0074] In this example, the valve cover 400 can include a support connection area 470 connecting the cover area 410 and the support area 430, and a stop connection area 480 connecting the cover area 410 and the closing stop area 460.

[0075] The support connection area 470 can include a first support connection area 471 connecting the cover area 410 and the first support area 431, and a second support connection area 472 connecting the cover area 410 and the second support area 432.

[0076] At least two of the cover area 410, the support connection area 470, and the support area 430 can be integrally formed. According to an embodiment of the present application, the cover area 410, the support connection area 470, and the support area 430 can all be integrally formed.

[0077] At least two of the cover area 410, the stop connection area 480, and the closing stop area 460 can be integrally formed. According to an embodiment of the present application, the cover area 410, the stop connection area 480, and the closing stop area 460 can all be integrally formed.

[0078] The valve disc 500 can be formed in a shape covering the flow path 210. When viewed from the other side of the first direction (a direction opposite to D1), a cross section of the valve disc 500 can cover a cross sectional area of the flow path 210 defined by the first inner surface 211 to close the flow path 210.

[0079] The valve disc 500 can include a disc area 510 and a rotation guide area 520. The disc area 510 can be made of a magnetic material and be supported by the rotation guide area 520. The rotation guide area 520 can be connected to the rotation shaft 440 while surrounding the disc area 510.

[0080] The valve disc 500 can rotate around the rotation shaft 440 between a closing position CP in which the flow path 210 is closed and an opening position OP in which the flow path 210 is opened. The valve disc 500 can rotate from the closing position CP to the opening position OP or from the opening position OP to the closing position CP.

[0081] A direction in which the valve disc 500 rotates from the closing position CP to the opening position OP can be referred to as a first rotation direction, and a direction in which the valve disc 500 rotates from the opening position OP to the closing position CP can be referred to as a second rotation direction.

[0082] The first rotation direction and the second rotation direction can be opposite to each other. The closing position CP of the valve disc 500 can be a position in which the valve disc 500 is disposed in a direction perpendicular to a direction of fluid flow, as shown in Figure 4 .

[0083] The open position OP of the valve disc 500 can be a position in which the valve disc 500 is arranged in a direction parallel to the fluid flow direction, as Figure 5 indicated.

[0084] For the structure of the embodiment, the disc region 510 can be formed of a magnetic material to be rotated by the electromagnetic coil 310, and the rotation guide region 520 can rotatably support the disc region 510.

[0085] The disc region 510 can have magnetic fields formed at opposite magnetic poles to each other, and can be provided in a cylindrical disc shape. The disc region 510 can include a first surface facing an upstream side with respect to the fluid flow direction at the closed position CP and a second surface which is a rear surface of the first surface facing a downstream side with respect to the fluid flow direction at the closed position CP.

[0086] As Figure 4 indicated, the valve disc 500 can be divided by the first support region 431 and the second support region 432 when viewed from the direction of the rotation shaft 440 in the closed position CP, and include a first magnetic pole portion facing the other side (a direction opposite to D3) of the third direction and a second magnetic pole portion facing the one side D3 of the third direction.

[0087] The first magnetic pole portion provided as a first magnetic pole (for example, N pole) and the second magnetic pole (portion) provided as a second magnetic pole opposite to the first magnetic pole (for example, S pole) can be arranged in opposite directions. The first magnetic pole and the second magnetic pole can be one and the other of N pole and S pole.

[0088] When the first magnetic pole portion is N pole and the second magnetic pole portion is S pole, the position of the valve disc 500 can be fixed to the closed position CP, or the valve disc 500 can be rotated toward the open position OP according to the direction of the current flowing into the electromagnetic coil 310.

[0089] When the valve disc 500 is positioned at the closed position CP, the first magnetic pole portion can be supported by the closed stop region 460. When viewed from the other side of the first direction (a direction opposite to D1), the magnetic field of the second magnetic pole (for example, S pole) can be induced at the upstream side with respect to the fluid flow direction and the magnetic field of the first magnetic pole (for example, N pole) can be induced at the downstream side with respect to the fluid flow direction when the current is applied through the electromagnetic coil 310 in a clockwise direction.

[0090] In this example, the region positioned at the upstream side of the fluid flow direction further than the first magnetic pole portion of the valve disc 500 can be offset by the magnetic field induced by the electromagnetic coil 310 to form a sparse magnetic field area.

[0091] The area located on the downstream side of the fluid flow direction from the first magnetic pole portion of the valve disc 500 can be reinforced by the magnetic field induced by the electromagnetic coil 310 to form a dense magnetic field area.

[0092] The area located on the upstream side of the fluid flow direction further from the second magnetic pole portion of the valve disc 500 can be reinforced by the magnetic field induced by the electromagnetic coil 310 to form a dense magnetic field area.

[0093] The area located on the downstream side of the fluid flow direction further from the second magnetic pole portion of the valve disc 500 can be cancelled by the magnetic field induced by the electromagnetic coil 310 to form a sparse magnetic field area.

[0094] Thus, when viewed in the spaced-apart state in the second direction (D2 or the direction opposite D2), the first magnetic pole can be spaced apart from the closing stop area 460 and rotated counterclockwise, and the second magnetic pole can also be rotated counterclockwise toward the opening stop member 450. In this example, the direction of rotation of the valve disc 500 can be a first direction of rotation.

[0095] When the valve disc 500 begins to rotate in the first direction of rotation, fluid can begin to flow through the flow path 210. When the first direction of rotation of the valve disc 500 continues, the valve disc 500 can interfere with the opening stop member 450, as shown in Figure 3 or Figure 5 .

[0096] In other words, the opening stop member 450 can prevent the valve disc 500 located at the open position OP from rotating in the first direction of rotation. When viewed in the spaced-apart state in the second direction (D2 or the direction opposite D2), the opening stop member 450 can be in contact with the second surface of the valve disc 500 located at the open position OP.

[0097] In this example, when viewed from the spaced-apart state in the second direction (D2 or the direction opposite D2), the rotation axis 440 can be disposed through the center of the flow path 210 with respect to the third direction (D3 or the direction opposite D3). Thus, when the valve disc 500 is located at the open position OP, the disc area 510 can be arranged off-center with respect to the third direction (D3 or the direction opposite D3) within the flow path 210.

[0098] Conversely, when viewed from the other side of the first direction (the opposite direction of D1), when a current is applied counterclockwise through the electromagnetic coil 310, the magnetic field of the first magnetic pole (e.g., N pole) can be induced on the upstream side with respect to the fluid flow direction, and the magnetic field of the second magnetic pole (e.g., S pole) can be induced on the downstream side with respect to the fluid flow direction.

[0099] In this example, the area located on the other side (the direction opposite to D3) of the third direction further than the first magnetic pole portion of the valve disc 500 can be relatively strongly canceled by the magnetic field induced by the electromagnetic coil 310 to form a dense magnetic field area.

[0100] The area located on the one side D3 of the third direction further than the first magnetic pole portion of the valve disc 500 can be relatively weakly canceled by the magnetic field induced by the electromagnetic coil 310 to form a dense magnetic field area.

[0101] The area located on the other side (the direction opposite to D3) of the third direction further than the second magnetic pole portion of the valve disc 500 can be relatively strongly reinforced by the magnetic field induced by the electromagnetic coil 310 to form a dense magnetic field area.

[0102] The area located on the one side D3 of the third direction further than the second magnetic pole portion of the valve disc 500 can be canceled by the magnetic field induced by the electromagnetic coil 310 to form a sparse magnetic field area.

[0103] Therefore, when viewed from a state spaced apart in the second direction from the one side D2, the second magnetic pole portion can be spaced apart from the opening stop member 450 and rotated clockwise, and the first magnetic pole portion can also be rotated clockwise toward the closing stop area 460. In this case, the direction of rotation of the valve disc 500 can be a second direction of rotation.

[0104] When the valve disc 500 starts to rotate in the second direction of rotation, the flow of fluid through the flow path 210 can be delayed. When the second direction of rotation of the valve disc 500 continues, the valve disc 500 can interfere with the closing stop area 460, as Figure 4 shown.

[0105] In other words, the closing stop area 460 can prevent the valve disc 500 located in the closing position CP from rotating in the second direction of rotation. The closing stop area 460 can be in contact with the second surface of the valve disc 500 located in the closing position CP when viewed in a state spaced apart in the second direction (D2 or the direction opposite to D2).

[0106] According to the above-described structure, within the flow path 210, the rotation of the valve disc 500 can be guided between the closing position CP in which the flow path 210 is closed and the opening position OP in which the flow path 210 is opened.

[0107] The portions of the first magnetic pole portion and the second magnetic pole portion of the disc area 510 are not limited thereto, and based on Figure 4 , the disc area 510 can be divided into the first magnetic pole portion facing the first surface of the valve disc 500 and the second magnetic pole portion facing the second surface thereof.

[0108] The positions of the valve disc 500 in the closed position CP and the open position OP can be fixed without a separate structure, and thus can smoothly allow or prevent the flow of fluid.

[0109] When the valve disc 500 is positioned in the closed position CP, the flow of fluid through the flow path 210 can be prevented, and in this example, the fluid can be stalled and frozen in a portion adjacent to the valve disc 500. In this example, when a high voltage is applied to the electromagnetic coil 310, the fluid flowing through the flow path 210 can be thawed.

[0110] Even to thaw the fluid, the valve body 200 and the bobbin body 320 can be integrally formed, rather than a structure in which the valve body 200 and the bobbin body 320 are separately disposed.

[0111] According to the structure of the embodiment, a high voltage can be applied to the electromagnetic coil 310 so that the fluid frozen at a portion adjacent to the valve disc 500 can be thawed by using heat generated by the electromagnetic coil 310 without a separate heater or the like.
