Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, and in particular to a gas valve with adjustable gas supply. Background Technology

[0002] The gas valve is the core control component of a gas stove. It is usually equipped with an inlet channel and an outlet channel. The inlet channel introduces gas, and the outlet channel is connected to the gas stove. The valve core and valve stem of the gas valve control the flow of gas.

[0003] In order to facilitate the adjustment of the gas intake volume through the gas valve according to the different firepower required when using the gas stove, the gas intake volume is usually adjusted by rotating the valve stem, which drives the valve core to switch different gas intake volumes.

[0004] In actual use, the fuel can be either natural gas or liquefied petroleum gas (LPG). Natural gas and LPG have different pressures during operation; LPG operates at a higher pressure. Therefore, under the same thermal power, the corresponding air intake of each adjustment port on the valve core can maintain normal operating power under the pressure of LPG. However, when using natural gas, because its pressure is lower, adjusting the heat output requires increasing the number of channels to achieve the same thermal power.

[0005] For a separate air supply structure, the valve body in related technologies is constructed by setting up an additional air supply channel, which complicates the valve body structure. Utility Model Content

[0006] In order to overcome at least one of the defects of the prior art, the present invention provides a gas valve with adjustable gas supply, which can guide the gas in the first chamber to supply gas when adjusting the firepower through the adjustment hole by setting a gas supply hole on the valve core and communicating with the gas supply groove.

[0007] The technical solution adopted by this utility model to solve its problem is: A gas valve with adjustable gas supply includes, The valve body is provided with an air inlet channel, an air outlet channel, a through hole, and a through cavity; the air inlet channel communicates with the through cavity, and the through hole is disposed on the side wall of the through cavity and communicates with the air outlet channel; A valve core assembly includes a valve core and an adjusting component. The valve core is rotatably mounted in the conduction cavity. The adjusting component drives the valve core to rotate. The valve core is provided with a flow guide cavity, a partition plate, an air outlet, an air inlet, an air inlet groove, and multiple adjusting holes. The partition plate is disposed in the flow guide cavity and divides the flow guide cavity into a first cavity segment and a second cavity segment, the second cavity segment being connected to the conduction cavity. The partition plate is provided with a flow guide hole. One end of the air inlet is connected to the first cavity segment, and the other end of the air inlet is connected to the air inlet groove. The air inlet groove extends circumferentially along the valve core. Multiple adjusting holes are spaced apart in the circumferential direction of the valve core and are connected to the second cavity segment. The air inlet groove and multiple adjusting holes are distributed axially along the valve core. One of the adjusting holes is used to connect with the conduction hole after the valve core rotates, and the air inlet groove is used to partially correspond to the conduction hole when the adjusting hole corresponds to the conduction hole. The air outlet is connected to the second cavity segment. A plugging head is movably installed in the first cavity section and is used to move closer to or away from the partition plate. The plugging head is used to block the guide hole after moving closer to the partition plate.

[0008] As an optional implementation, the plugging head includes a plugging section and an adjusting section. The outer diameter of the plugging section gradually decreases from the end away from the guide hole to the end close to the guide hole. The adjusting section rotates with the inner wall of the first cavity section and guides the plugging head to move closer to or away from the guide hole during rotation.

[0009] As an optional implementation, the outer wall of the adjustment section is provided with a first threaded structure, and the inner wall of the first cavity section is provided with a second threaded structure, wherein the second threaded structure is threadedly engaged with the first threaded structure.

[0010] As an optional implementation, a sealing ring is provided between the top end of the adjustment section and the top end of the first cavity section.

[0011] As an optional implementation, the adjusting member includes an adjusting rod, an adjusting cavity is provided at the top of the valve core, and the bottom end of the adjusting rod is rotatably inserted through the adjusting cavity; a first positioning part is provided on the adjusting rod, and a second positioning part is provided on the side wall of the adjusting cavity, the second positioning part being positioned and abutting against the first positioning part; an adjusting channel is provided inside the adjusting rod, one end of the adjusting channel extending to the top surface of the adjusting rod, and the other end of the adjusting channel extending to the top of the adjusting section.

[0012] As an optional implementation, the adjusting member further includes an elastic component; the top end of the elastic component is connected to the bottom end of the adjusting rod, and one end of the elastic component abuts against the adjusting section.

[0013] As an optional implementation, the first positioning part includes a positioning block, and the second positioning part includes a positioning notch, wherein the positioning block is fitted into the positioning notch.

[0014] As an optional implementation, the top end of the adjustment section is provided with an adjustment groove.

[0015] As an optional implementation, a plurality of the adjustment holes are disposed below the adjustment groove.

[0016] As an optional implementation, the diameters of the plurality of adjustment holes may increase or decrease sequentially in the rotation direction of the valve core.

[0017] In summary, this utility model has the following technical effects: 1. Gas replenishment is required. By moving the sealing head away from the partition plate, the guide hole on the partition plate is opened. After the gas in the guide cavity enters the second chamber, some gas enters the first chamber through the guide hole. It is then guided to the gas replenishment hole through the first chamber and then enters the gas replenishment groove through the gas replenishment hole. The gas replenishment groove is used to replenish gas in the part corresponding to the guide hole, in order to supplement the gas discharged from the regulating hole and ensure normal combustion power.

[0018] 2. Because the air replenishment groove extends circumferentially from the valve core, it corresponds to different adjustment holes with corresponding air replenishment groove segments when the valve core rotates. Regardless of which adjustment hole is connected to the guide hole, there is a corresponding air replenishment groove segment, achieving continuous air replenishment. During processing, the circumferentially extending air replenishment groove ensures continuous air replenishment positions. Compared to a single air replenishment hole, it allows for continuous air replenishment during rotation without the need for alignment operations, resulting in higher air replenishment efficiency.

[0027] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0028] See Figures 1-8 This utility model discloses a gas valve with adjustable gas supply, including a valve body 10, a valve core assembly, and a sealing head 40. The valve body 10 is provided with an inlet channel 11, an outlet channel 12, a through hole 14, and a through cavity 13. The inlet channel 11 communicates with the through cavity 13, and the through hole 14 is located on the side wall of the through cavity 13, communicating with the outlet channel 12. The valve core assembly includes a valve core 30 and an adjusting component. The valve core 30 is rotatably mounted in the through cavity 13, and the adjusting component can drive the valve core 30 to rotate.

[0029] Specifically, the valve core 30 is provided with a flow guide cavity, a partition plate 33, an air outlet 34, an air replenishment hole 37, an air replenishment groove 36, and multiple adjustment holes 35. The partition plate 33 is disposed in the flow guide cavity, dividing the flow guide cavity into a first cavity segment 31 and a second cavity segment 32. The second cavity segment 32 is connected to the flow guide cavity 13. The partition plate 33 is provided with a flow guide hole 331. One end of the air replenishment hole 37 is connected to the first cavity segment 31, and the other end of the air replenishment hole 37 is connected to the air replenishment groove 36. The air replenishment groove 36 extends along the valve core 30. Extending circumferentially, multiple adjustment holes 35 are spaced apart in the circumferential direction of the valve core 30, and the multiple adjustment holes 35 are connected to the second cavity section 32; the air supply groove 36 and the multiple adjustment holes 35 are distributed in the axial direction of the valve core 30; one of the adjustment holes 35 is used to connect with the corresponding through hole 14 after the valve core 30 rotates, and the air supply groove 36 is used to partially correspond with the through hole 14 when the adjustment hole 35 corresponds with the through hole 14, the air outlet 34 is connected to the second cavity section 32, and is connected with the corresponding through hole 14 when the valve core 30 rotates.

[0030] In addition, the aforementioned plugging head 40 is movably installed in the first cavity section 31. The plugging head 40 can move closer to or further away from the partition plate 33. When the plugging head 40 moves closer to the partition plate 33, it blocks the guide hole 331. When the plugging head 40 moves further away from the partition plate 33, it opens the guide hole 331.

[0031] Based on the above structure, when using the gas valve with adjustable gas supply of this utility model, the gas pipeline can be connected to the gas inlet channel 11, and the gas outlet channel 12 can be connected to the gas stove. When using gas, the valve on the gas pipeline is opened, and the gas in the gas pipeline can be introduced into the guiding cavity 13 through the gas inlet channel 11. The gas in the guiding cavity 13 can enter the second cavity section 32.

[0032] When using gas normally, the valve core 30 is rotated by the adjusting component to align the gas outlet 34 with the guide hole 14. At this time, the gas can be guided to the gas stove through the second chamber 32, the gas outlet 34, the guide hole 14, and the gas outlet channel 12 for combustion.

[0033] When the firepower needs to be adjusted, the adjusting element can be rotated to one of the adjusting holes 35 and the through hole 14. At this time, the gas in the second chamber 32 can be guided to the gas stove through the adjusting hole 35, the through hole 14 and the gas outlet channel 12. When the valve core 30 is rotated to different adjusting holes 35 and through holes 14, the firepower can be adjusted.

[0034] When the gas pressure is insufficient, such as when using natural gas as fuel, or when the gas supply pressure is low, the gas pressure is insufficient when the gas is directly discharged from the regulating hole 35 to the guide hole 14 and guided to the gas outlet channel 12. Under the same gas supply speed, insufficient gas supply will result in lower gas thermal power. In this case, a gas replenishment operation is required. By moving the sealing head 40 away from the partition plate 33, the guide hole 331 on the partition plate 33 is opened. After the gas in the guide cavity 13 enters the second cavity section 32, some gas enters the first cavity section 31 through the guide hole 331. It is then guided to the gas replenishment hole 37 through the first cavity section 31, and then enters the gas replenishment groove 36 through the gas replenishment hole 37. The gas replenishment groove 36 is used to replenish the gas corresponding to the part of the guide hole 14, in order to supplement the gas discharged from the regulating hole 35 and make the combustion power normal.

[0035] It should be noted that since the air replenishment groove 36 extends circumferentially from the valve core 30, when the valve core 30 rotates, it corresponds to different adjustment holes 35 with segments of the air replenishment groove 36. Regardless of which adjustment hole 35 is connected to the through hole 14, there is a corresponding segment of the air replenishment groove 36, achieving continuous air replenishment. During processing, the circumferentially extending air replenishment groove 36 provides continuous air replenishment positions. Compared to a single air replenishment hole 37, it allows for continuous air replenishment during rotation without the need for alignment of the air replenishment positions, resulting in higher air replenishment efficiency.

[0036] Of course, when the gas pressure is normal and no gas replenishment is required, the guide hole 331 can be blocked by moving the sealing head 40 toward the partition plate 33. At this time, the gas introduced into the guide cavity 13 will not enter the first cavity 31, but will be concentrated in the second cavity 32 and discharged through the gas outlet 34 or the regulating hole 35 of the second cavity 32, so that the gas utilization rate is higher.

[0037] As an optional implementation, the sealing head 40 in this embodiment includes a sealing section 41 and an adjusting section 42. The outer diameter of the sealing section 41 gradually decreases from the end away from the guide hole 331 to the end closer to the guide hole 331. The adjusting section 42 rotates with the inner wall of the first cavity section 31 and guides the sealing head 40 to move closer to or away from the guide hole 331 during rotation. Based on this structure, when adjusting the position of the sealing head 40, since the outer diameter of the sealing section 41 gradually decreases from the end away from the guide hole 331 to the end closer to the guide hole 331... As one end of the guide hole 331 gradually decreases in size, the outer wall of the sealing section 41 can cooperate with the inner wall of the bottom end of the first cavity section 31 to form a certain flow guiding interval. When the guide hole 331 is opened, the adjusting section 42 is rotated to move away from the partition plate 33. When the guide hole 331 is opened, the gas in the second cavity section 32 can enter the first cavity section 31 through the guide hole 331. The flow guiding interval between the outer wall of the sealing section 41 and the inner wall of the first cavity section 31 can guide the gas to flow to the gas replenishment hole 37, thus achieving gas replenishment.

[0038] Of course, when the blocking section 41 is driven to move toward the partition plate 33, the adjusting section 42 can be rotated in the opposite direction to drive the blocking section 41 to move closer to the partition plate 33 and block the guide hole 331, so that the second cavity section 32 is separated from the first cavity section 31.

[0039] It should be noted that in the relevant implementation structure, the outer wall of the adjusting section 42 is provided with a first threaded structure 421, and the inner wall of the first cavity section 31 is provided with a second threaded structure. The second threaded structure is threadedly engaged with the first threaded structure 421. Thus, by rotating the adjusting section 42, the first threaded structure 421 is threadedly engaged with the second threaded structure on the inner wall of the first cavity section 31, thereby enabling the adjusting section 42 to move closer to or further away from the partition plate 33.

[0040] In other implementation structures, a spiral groove or inclined groove can be provided on the outer peripheral wall of the adjustment section 42, and a guide post can be provided on the inner wall of the first cavity section 31. The guide post can be slidably assembled in the spiral groove or inclined groove structure. When the adjustment section 42 rotates, the guide post slides in the spiral groove or inclined groove, which can guide the adjustment section 42 to move up and down, so as to move the blocking section 41 closer to or away from the partition plate 33.

[0041] As an optional implementation, a sealing ring can be provided between the top end of the adjusting section 42 and the top end of the first cavity section 31. This sealing ring can be provided to avoid the first threaded structure 421 on the adjusting section 42, specifically above the first threaded structure 421. Since there may be gas leakage in the gap of the threaded fit, a sealing ring can be provided at the top end of the adjusting section 42. Even if the gas flows upward and overflows through the gap of the threaded structure, the sealing ring above will seal and block it, preventing gas leakage.

[0042] As an optional implementation, the adjusting member in this embodiment includes an adjusting rod 20, and an adjusting cavity 39 is provided at the top of the valve core 30. The bottom end of the adjusting rod 20 is rotatably inserted into the adjusting cavity 39. A first positioning part is provided on the adjusting rod 20, and a second positioning part is provided on the side wall of the adjusting cavity 39. The second positioning part and the first positioning part are positioned and abut against each other.

[0043] When the valve core 30 is rotated, the adjusting rod 20 is rotated. When the adjusting rod 20 rotates, the first positioning part and the second positioning part are positioned and abutted together. Therefore, when the adjusting rod 20 rotates, the first positioning part can push the second positioning part to rotate, thereby driving the valve core 30 to rotate.

[0044] Since the plugging head 40 is located inside the valve core 30, and the adjusting rod 20 is assembled in the adjusting cavity 39 of the valve core 30, which is located above the first cavity section 31, an adjusting channel 22 can be provided inside the adjusting rod 20 to facilitate the adjustment of the plugging head 40. One end of the adjusting channel 22 extends to the top surface of the adjusting rod 20, and the other end extends to the top of the adjusting section 42. When performing the air replenishment operation, the user can use a tool to insert through the adjusting channel 22 and guide it to the top of the adjusting section 42 to adjust the plugging head 40.

[0045] Specifically, a magnetic structure can be set in the sealing head 40, and a corresponding magnetic structure can also be set in the gas replenishment adjustment tool, such as a screwdriver. The screwdriver can be inserted into the adjustment channel 22 and attached to the adjustment section 42 of the sealing head 40, thereby driving the adjustment section 42 to rotate.

[0046] Of course, an adjustment groove can also be provided at the top of the adjustment section 42. When the screwdriver operates the adjustment section 42 of the sealing head 40, the screwdriver can be inserted into the adjustment groove and make contact with the adjustment groove, thereby driving the adjustment section 42 to rotate.

[0047] As an optional implementation, the adjusting member in this embodiment also includes an elastic member 23. The top end of the elastic member 23 is connected to the bottom end of the adjusting rod 20, and one end of the elastic member 23 abuts against the adjusting section 42. In this way, the elastic stress provided by the elastic member 23 can press the adjusting rod 20 and the adjusting section 42 of the sealing head 40 tightly, and the sealing head 40 can remain in a downward state under the action of elastic stress, thereby reducing the possibility of gas leakage caused by the sealing head 40 becoming loose.

[0048] Based on this structure, the first and second positioning parts can be assembled in a sliding state. When the valve core 30 does not need to be rotated, the elastic stress provided by the elastic component 23 can drive the adjusting rod 20 to move upward. At this time, the first positioning part on the adjusting rod 20 slides to a state of disengagement from the first positioning part. When the valve core 30 needs to be rotated, the adjusting rod 20 can be pressed down, causing the adjusting rod 20 to move downward, and the first positioning part slides to a state of mutual abutment with the second positioning part, thereby realizing the rotation adjustment of the valve core 30. In this way, when the valve core 30 does not need to be rotated, the first and second positioning parts of the adjusting rod 20 are disengaged under the action of the elastic component 23, preventing accidental rotation of the valve core 30 in case of accidental contact.

[0049] More specifically, the first positioning part includes a positioning block 21, and the second positioning part includes a positioning notch 38. The positioning block 21 is fitted into the positioning notch 38, and the positioning block 21 can slide with the positioning notch 38. Under the action of the elastic member 23, the top end of the adjusting rod 20 can remain extended out of the valve body 10. When adjusting the air supply, the elastic member 23 can be compressed by pressing the adjusting rod 20. The bottom end of the adjusting channel 22 can remain relatively close to the adjusting section 42, which facilitates the insertion and adjustment of the screwdriver.

[0050] As an optional implementation, multiple adjustment holes 35 are disposed below the adjustment groove, so that the gas replenishment position is above the gas guide position of the adjustment hole 35. Therefore, the gas introduced by the adjustment hole 35 can be normally connected with the guide hole 14, while a small amount of gas replenishment can be replenished above the guide hole 14.

[0051] As an optional implementation, the diameters of the multiple adjustment holes 35 increase or decrease sequentially in the rotation direction of the valve core 30. In this way, when the valve core 30 rotates, the diameters of the adjustment holes 35 on the valve core 30 change gradually, and thus the firepower also changes gradually during the rotation process, making operation more convenient.

[0052] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
