Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and in particular relates to a stopcock valve and a gas stove. Background Technology

[0002] Gas stoves are widely used. Most household gas stoves are regulated by mechanical stopcock valves. By rotating the stopcock valve, the channel on the valve core can be connected or separated from the channel on the valve body, thus opening or closing the stove.

[0003] The rotation of the valve core is achieved by the user operating the valve stem. Existing plug valves have poor positioning stability when rotating to multiple fire positions, resulting in inaccurate gas flow and difficulty in obtaining precise flame control. Users cannot achieve the ideal fire level when adjusting, resulting in a poor user experience. In addition, the user has a poor feel when controlling the plug valve to switch between different fire levels, and the overall structure of the plug valve is relatively complex, with high manufacturing costs and difficult assembly and maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a stopcock valve and a gas stove to solve the problems of poor positioning of existing stopcock valves at different fire positions and inability to accurately control the flame size.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In one aspect, this utility model provides a plug valve, which includes: A valve body having a valve cavity thereon, and at least one gear positioning member being provided on the valve body along the circumference of the valve cavity. The gear positioning member includes an elastic part and a limiting part connected to the elastic part. The limiting part moves radially along the valve cavity under the action of the elastic part. A valve stem is rotatably connected in the valve cavity. The valve stem is provided with a gear adjustment part corresponding to the position of the gear positioning member. An adjustment section is provided on the periphery of the gear adjustment part, and the adjustment section includes at least two gear recesses.

[0006] In some embodiments of this application, the gear position recess is a groove structure formed on the outer wall of the gear position adjustment part and extending toward the central axis of the valve stem, and a transition slope is formed on the side wall of the gear position recess.

[0007] The transition slope on the side wall of the gear position recess makes it easier for the user to shift gears, and the positioning part moves more smoothly into or out of the gear position recess.

[0008] In some embodiments of this application, the gear positioning component further includes a positioning part, the elastic part is connected to the positioning part, and a mounting part is provided in the valve body along the radial direction of the valve cavity, and the positioning part is movably connected in the mounting part.

[0009] When the positioning part moves along the mounting part toward the valve cavity, the amount of deformation of the elastic part increases, and the switching force when adjusting the gear increases. When the positioning part moves away from the valve cavity along the mounting part, the amount of deformation of the elastic part is reduced, and the switching force when adjusting the gear is reduced.

[0010] In some embodiments of this application, an internal thread is formed in the mounting portion, and an external thread adapted to the internal thread is formed on the outer wall of the positioning portion, and the positioning portion is threadedly connected to the mounting portion.

[0011] The positioning part is movably connected to the mounting part by a threaded connection, and its position within the mounting part can be changed by rotating the positioning part.

[0012] In some embodiments of this application, the positioning part is provided with a connecting groove at the first end near the valve cavity, one end of the elastic member is fixed in the connecting groove, and the other end of the elastic member is connected to a limiting part, which is spherical.

[0013] The spherical limiting part moves more smoothly into and out of the gear position recess, which helps to reduce resistance.

[0014] In some embodiments of this application, the second end of the positioning part away from the valve cavity is provided with an operating groove, and the cross-sectional shape of the operating groove is non-circular.

[0015] Users can insert tools such as screwdrivers into the operating slot to easily rotate the positioning part and move it back and forth within the mounting part.

[0016] In some embodiments of this application, the valve body includes a valve seat and a valve cover, the valve cover being detachably connected to the valve seat, and the gear positioning element being disposed on the valve seat or the valve cover.

[0017] In some embodiments of this application, the valve seat has a mounting surface that is perpendicular to the axial direction of the valve cavity, the mounting surface has a fixing hole, and the valve cover has mating holes that correspond one-to-one with the fixing holes. Fasteners achieve a detachable connection between the valve cover and the valve seat through the fixing holes and the mating holes.

[0018] In some embodiments of this application, the valve stem is provided with a stop portion, and the valve seat is provided with an arc-shaped stop groove on the inner wall of the valve cavity. The stop portion is configured to be movably connected in the stop groove as the valve stem rotates.

[0019] The stop moves within the stop groove, limiting the rotation range of the valve stem, ensuring high operational safety and reliability.

[0020] In another aspect, this utility model also proposes a gas stove that includes the stopcock valve mentioned in any of the above claims.

[0031] refer to Figures 1-3 In one aspect, this utility model proposes a plug valve, which includes a valve body 100 and a valve stem 200. The valve body 100 is provided with a valve cavity, and the valve stem 200 is rotatably connected in the valve cavity. By rotating the valve stem 200, the size of the gas supply channel can be changed, thereby controlling the gas stove to turn on or off or adjusting the flame.

[0032] Along the circumference of the valve cavity, at least one gear positioning member 300 is provided on the valve body 100. The gear positioning member 300 includes an elastic part 320 and a limiting part 330 connected to the elastic part 320. The limiting part 330 moves radially along the valve cavity under the action of the elastic part 320.

[0033] The valve stem 200 is provided with a gear adjustment part 210 corresponding to the position of the gear positioning part 300. The gear adjustment part 210 is provided with an adjustment section on its periphery, and the adjustment section includes at least two gear recesses 211.

[0034] Combination Figure 6The valve stem 200 is rotatably connected to the valve cavity of the valve body 100, and the valve stem 200 is provided with a gear adjustment part 210. The gear adjustment part 210 is provided with at least two gear recesses 211. The valve body 100 is provided with a gear positioning member 300. The limiting part 330 on the gear positioning member 300 moves back and forth towards the gear recesses 211 under the action of the elastic part 320. The limiting part 330 is engaged in different gear recesses 211 to realize the adjustment of different fire positions of the gas stove, so as to make the gas flow accurate and the positioning stability good. The entire plug valve has a simple structure, low manufacturing cost, and is convenient for installation and maintenance.

[0035] Specifically, the gear adjustment part 210 is an annular protrusion formed on the valve stem 200, and the radial dimension of the gear adjustment part 210 is larger than the radial dimension of the valve stem 200.

[0036] The adjustment section is formed on the outer wall of the gear adjustment part 210. Since the adjustment range of a gas stove is generally within 180 degrees, the adjustment section is designed to be formed on part of the outer wall of the gear adjustment part 210.

[0037] The adjustment section includes at least two level recesses 211. In order to increase the number of levels of gas stove firepower adjustment, multiple level recesses 211 are provided on the adjustment section. In addition to the gas stove switch, multiple firepower levels can be adjusted, such as, but not limited to, high, medium and low levels.

[0038] In some embodiments of this application, the gear position recess 211 is a groove structure formed on the outer wall of the gear position adjustment portion 210 and extending toward the central axis of the valve stem 200.

[0039] Under the action of the elastic part 320, the limiting part 330 is engaged in the gear position recess 211. The gear position recess 211 provides a limit for the limiting part 330. When the user adjusts to the gear position recess 211 corresponding to the target firepower, the limiting part 330 is engaged in the corresponding gear position recess 211. This can avoid the problems of poor positioning stability when the plug valve is rotated to multiple firepower positions, resulting in inaccurate gas flow and difficulty in obtaining precise flame control.

[0040] A transition slope is formed on the side wall of the gear position recess 211. The transition slope on the side wall of the gear position recess 211 makes it easier for the user to shift gears, and the positioning part 310 can move into or out of the gear position recess 211 more smoothly.

[0041] In other words, the adjustment section includes multiple adjustment teeth, and a gear position recess 211 is formed between the adjustment teeth. During rotation, the gear position recess 211 between the adjustment teeth provides positioning for the positioning part 310. During the rotation of the valve stem 200, a resistance is formed between the limiting part 330 at the top of the elastic part 320 and the adjustment teeth. Unless this resistance is overcome, the valve stem 200 will always be in this gap, thus achieving the function of gear position positioning.

[0042] When a gear shift is required, the user applies a rotational force to the valve stem 200, causing the limiting part 330 to overcome the resistance and move out of the gear position recess 211 to another gear position recess 211.

[0043] refer to Figure 4 , Figure 5 In some embodiments of this application, the gear positioning member 300 further includes a positioning part 310, an elastic part 320 is connected to the positioning part 310, and a mounting part 112 is provided in the valve body 100 along the radial direction of the valve cavity, and the positioning part 310 is movably connected in the mounting part 112.

[0044] When the positioning part 310 moves along the mounting part 112 toward the valve chamber, the amount of deformation of the elastic part 320 increases, and the switching force when adjusting the gear increases.

[0045] When the positioning part 310 moves along the mounting part 112 in a direction away from the valve cavity, the amount of deformation of the elastic part 320 is reduced, and the switching force when adjusting the gear is reduced.

[0046] In some embodiments of this application, an internal thread is formed in the mounting portion 112, and an external thread adapted to the internal thread is formed on the outer wall of the positioning portion 310, and the positioning portion 310 is threadedly connected to the mounting portion 112.

[0047] The positioning part 310 is movably connected to the mounting part 112 by means of a threaded connection. By rotating the positioning part 310, its position within the mounting part 112 can be changed.

[0048] That is, the gear positioning component 300 is movably connected to the mounting part 112 through the positioning part 310, and the tightness of the connection between the limiting part 330 and the gear adjustment part 210 can be adjusted to adjust the gear shifting force, making it more operable.

[0049] In some embodiments of this application, the first end of the positioning part 310 near the valve cavity is provided with a connecting groove 311, one end of the elastic member is fixed in the connecting groove 311, and the other end of the elastic member is connected to the limiting part 330, which is spherical.

[0050] The elastic element is always in a compressed state. When the valve stem 200 rotates to the position where the limit part 330 corresponds to the position of the gear recess 211, the elastic element pushes the positioning part 310 forward into the gear recess 211 under its own restoring force.

[0051] As the valve stem 200 rotates and the limiting part 330 moves out of the position recess 211, the elastic element is gradually compressed.

[0052] The spherical limiting part 330 moves more smoothly into and out of the gear recess 211, which helps to reduce resistance.

[0053] In some embodiments of this application, the second end of the positioning part 310 away from the valve cavity is provided with an operation groove 312, and the cross-sectional shape of the operation groove 312 is non-circular.

[0054] Users can insert tools such as screwdrivers into the operating slot 312 to facilitate the rotation of the positioning part 310, thereby enabling it to move back and forth within the mounting part 112.

[0055] The connecting groove 311 and the operating groove 312 are located at both ends of the positioning part 310, and both are blind hole structures. The connecting groove 311 is used to provide a connection base for the elastic element and to provide a limit during the compression and elongation of the elastic element to prevent deformation of the elastic element. The operating groove 312 allows the user to adjust the installation depth of the positioning part 310 in the mounting part 112, thereby adjusting the force when shifting gears.

[0056] refer to Figures 6-8 In order to improve the safety of the plug valve when rotating and shifting gears, the rotation range of the plug valve is limited. In some embodiments of this application, a stop portion 220 is provided on the valve stem 200, and an arc-shaped stop groove portion 122 is provided on the inner wall of the valve cavity corresponding to the valve seat 120. The stop portion 220 is configured to be movably connected in the stop groove portion 122 as the valve stem 200 rotates.

[0057] The stop groove 122 is a groove structure with an opening at the top. The valve stem 200 is installed in the valve cavity from top to bottom. When the valve stem 200 is installed, the stop part 220 moves into the stop groove 122.

[0058] As the valve stem 200 rotates, the stop part 220 moves within the stop groove part 122, limiting the rotation range of the valve stem 200, thus ensuring high operational safety and reliability.

[0059] Refer again Figure 2 In some embodiments of this application, the valve body 100 includes a valve seat 120 and a valve cover 110, the valve cover 110 being detachably connected to the valve seat 120, and the gear positioning member 300 being disposed on the valve seat 120 or the valve cover 110.

[0060] The valve cavity includes a first valve cavity 101 formed on the valve cover 110 and a second valve cavity 102 formed on the valve seat 120, with a stop groove 122 formed on the inner wall of the second valve cavity 102.

[0061] The aforementioned detachable structure of the valve body 100 facilitates processing and assembly. The valve cover 110 is placed on top of the valve seat 120, which helps to limit the axial movement of the valve stem 200. The stop portion 220 is confined within the stop groove portion 122 by the valve cover 110, preventing the valve stem 200 from coming off upward.

[0062] In some embodiments of this application, the valve seat 120 has a mounting surface that is perpendicular to the axial direction of the valve cavity, and a fixing hole 121 is provided on the mounting surface. The valve cover 110 has mating holes 111 that correspond one-to-one with the fixing holes 121. Fasteners achieve a detachable connection between the valve cover 110 and the valve seat 120 through the fixing holes 121 and the mating holes 111.

[0063] The position and number of fixing holes 121 and mating holes 111 are determined according to the actual assembly requirements. That is, multiple fixing holes 121 can be provided at intervals on the valve seat 120, and the number of mating holes 111 corresponds to the number of fixing holes 121.

[0064] In some embodiments, the fixing hole 121 and the mating hole 111 are both through holes, and the fastener is a bolt. The bolt passes through the fixing hole 121 and the mating hole 111 and is fixed by a nut.

[0065] In other embodiments, the fixing hole 121 is a threaded hole, the mating hole 111 is a through hole structure, and the fastener is a bolt. The front end of the fastener passes through the mating hole 111 and is threaded into the fixing hole 121, which can also achieve the connection and fixation of the valve cover 110 and the valve seat 120.

[0066] In another aspect, this utility model also proposes a gas stove that includes the stopcock valve mentioned in any of the above claims.
