Description

Technical Field

[0001] This utility model belongs to the field of plug valve technology, specifically relating to a synchronous electrically controlled two-stage regulating plug valve. Background Technology

[0002] A plug valve is a type of gas valve commonly used in civil gas appliances. This valve is used for manual operation to control the switching of gas supply and to adjust the flame intensity by rotating the gear controller.

[0003] Current stopcock valves often have multiple gas outlet channels, but they cannot achieve precise firepower control of multiple gas outlet channels through a single control knob. Their adjustability is poor and cannot meet users' needs for more precise firepower when cooking with a gas stove. Summary of the Invention

[0004] This invention addresses the aforementioned problems in the existing technology by proposing a synchronous, electrically controlled, two-stage regulating plug valve that enables precise fire control of multiple fire channels.

[0005] This utility model can be achieved through the following technical solutions:

[0006] A synchronous electrically controlled two-stage regulating plug valve, comprising:

[0007] The valve body has an air intake chamber, a main ignition channel and a secondary ignition channel. A valve core cavity is provided between the air intake chamber, the main ignition channel and the secondary ignition channel. The air intake chamber is connected to the valve core cavity. The main ignition channel and the secondary ignition channel are arranged in parallel and are connected to the valve core cavity.

[0008] A valve core is rotatably mounted in the valve core cavity, and the communication area between the intake cavity and the valve core cavity is adjusted by rotating the valve core.

[0009] A flow regulating plate is connected to the valve core and rotates synchronously with the rotation of the valve core. The flow regulating plate has a flow regulating hole. The gas entering the intake chamber flows into the valve core cavity through the flow regulating hole and is then distributed to the main ignition channel and the secondary ignition channel.

[0010] The motor is linked to the valve core and drives the valve core to rotate, thereby synchronously adjusting the flame output of the main fire channel and the secondary fire channel.

[0011] As a further improvement of this utility model, it also includes a valve core coupling, which is connected to the valve core, and the motor is connected to the valve core coupling via a gear set.

[0012] As a further improvement of this utility model, the gear set includes a transmission gear assembly and a drive gear, the front and rear sides of the valve core coupling are respectively connected to the valve core and the drive gear, and the transmission gear assembly meshes with the drive gear.

[0013] As a further improvement of this utility model, a Hall sensor is also provided between the drive gear and the valve core coupling. The Hall sensor and the valve core coupling have three position sensing points, namely the flame-off sensing point, the maximum flame sensing point, and the flame-keeping sensing point.

[0014] As a further improvement of this utility model, it also includes a rear cover, which is installed on the back of the valve body, and a space is reserved between the rear cover and the valve body to form a rear cover cavity.

[0015] As a further improvement of this utility model, the valve body also has an electromagnetic valve cavity, on which an electromagnetic valve is installed and has an air inlet and an air outlet. The electromagnetic valve cavity and the rear cover cavity form the air inlet cavity. The connection between the air inlet and the air outlet of the electromagnetic valve cavity is opened or closed by energizing or de-energizing the electromagnetic valve.

[0016] As a further improvement of this utility model, the valve body has a first valve body air inlet and a second valve body air inlet, wherein,

[0017] The first valve body air inlet, the rear cover cavity, the solenoid valve cavity air inlet, the solenoid valve cavity air outlet, the second valve body air inlet, and the valve core cavity are connected in sequence.

[0018] As a further improvement of this utility model, a sealing gasket is provided between the flow regulating plate and the valve body. The sealing gasket has a through hole for the flow regulating hole to communicate with the air inlet of the second valve body. As the flow regulating plate rotates, the conduction area between the flow regulating hole and the air inlet of the second valve body is changed, thereby changing the amount of air entering the valve core cavity.

[0019] As a further improvement of this utility model, a first spring is provided between the flow regulating plate and the rear cover, and the flow regulating plate and the sealing gasket are pressed tightly onto the valve body by the first spring.

[0020] As a further improvement of this utility model, the valve core also has a spring cavity, in which a second spring is installed, and the two ends of the second spring abut against the valve core and the valve core coupling, respectively.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Gas enters the valve core cavity through the flow regulation hole of the flow regulation plate, and is then distributed to the main fire channel and the secondary fire channel, thereby realizing synchronous flow regulation of the two channels;

[0023] 2. The electronic control adjustment method, combined with the setting of the flow adjustment plate, enables precise control of the flame size of the two channels, thereby meeting the needs for more precise heat in the cooking process;

[0024] 3. The Hall sensor and valve core coupling have three position sensing points, namely the flame-off sensing point, the maximum flame sensing point, and the flame-keeping sensing point. Through the setting of the Hall sensor, the motor can accurately adjust the valve core to the flame-off position, the maximum flame position, and the flame-keeping position.

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0042] Example 1

[0043] like Figure 1-6 As shown, this utility model provides a synchronous electrically controlled two-stage regulating plug valve, comprising:

[0044] The valve body 100 has an air intake chamber, a main fire channel 110 and a secondary fire channel 120. A valve core chamber is provided between the air intake chamber and the main fire channel 110 and the secondary fire channel 120. The air intake chamber is connected to the valve core chamber. The main fire channel 110 and the secondary fire channel 120 are arranged in parallel and are connected to the valve core chamber.

[0045] The valve core 130 is rotatably mounted in the valve core cavity, and the communication area between the intake cavity and the valve core cavity is adjusted by the rotation of the valve core 130.

[0046] The flow regulating plate 140 is connected to the valve core 130 and rotates synchronously with the rotation of the valve core 130. The flow regulating plate 140 has flow regulating holes 141 with different apertures. The gas entering the intake chamber flows into the valve core chamber through the flow regulating holes 141 and is then distributed to the main fire channel 110 and the secondary fire channel 120.

[0047] The motor 150 is linked to the valve core 130. The motor 150 drives the valve core 130 to rotate, and synchronously adjusts the flame output of the main flame channel 110 and the secondary flame channel 120.

[0048] In other words, the gas needs to enter the valve core cavity through the flow regulation hole 141 of the flow regulation plate 140, and then be distributed to the main fire channel 110 and the secondary fire channel 120, thereby realizing the synchronous flow regulation of the two channels. The electronic control regulation method, combined with the setting of the flow regulation plate 140, enables the flame size of the two channels to be precisely controlled, thereby satisfying the need for more precise firepower during cooking.

[0049] Preferably, the system also includes a valve core coupling 160, which is connected to the valve core 130 via a pin. The motor 150 is connected to the valve core coupling 160 via a gear set. Specifically, the gear set includes a transmission gear assembly 151 and a drive gear 152. The front and rear sides of the valve core coupling 160 are connected to the valve core 130 and the drive gear 152, respectively. The transmission gear assembly 151 and the drive gear 152 mesh, meaning that the motor 150 drives the transmission gear assembly 151 to rotate, thereby driving the drive gear 152 to rotate. The rotation of the drive gear 152 then sequentially drives the valve core coupling 160, the valve core 130, and the flow regulating plate 140 to rotate, thereby achieving the purpose of synchronously regulating the flame output of the main fire channel 110 and the secondary fire channel 120.

[0050] Preferably, a Hall sensor 170 is also provided between the drive gear 152 and the valve core coupling 160. The Hall sensor 170 and the valve core coupling 160 have three position sensing points 171, namely the flame-off sensing point, the maximum flame sensing point, and the flame-keeping sensing point. It is through the setting of the Hall sensor 170 that the motor 150 can accurately adjust the valve core 130 to the flame-off position, the maximum flame position, and the flame-keeping position.

[0051] Preferably, it also includes a rear cover 180, which is installed on the back of the valve body 100. A space is reserved between the rear cover 180 and the valve body 100 to form a rear cover cavity 181. A rear cover sealing ring 182 is provided between the rear cover 180 and the valve body 100 to ensure the sealing of the rear cover cavity 181.

[0052] Preferably, the valve body 100 also has a solenoid valve cavity, on which a solenoid valve 190 is installed and has a solenoid valve cavity air inlet 191 and a solenoid valve cavity air outlet 192. The solenoid valve cavity and the rear cover cavity 181 form the aforementioned air inlet cavity. The connection between the solenoid valve cavity air inlet 191 and the solenoid valve cavity air outlet 192 is opened or closed by energizing or de-energizing the solenoid valve 190.

[0053] That is, the gas outlet 192 of the solenoid valve cavity will only open when the solenoid valve 190 is energized, so that the gas can smoothly enter the rear cover cavity 181.

[0054] Preferably, the valve body 100 has a first valve body air inlet 101 and a second valve body air inlet 102, wherein the first valve body air inlet 101, the solenoid valve cavity air inlet 191, the solenoid valve cavity air outlet 192, the rear cover cavity 181, the second valve body air inlet 102, and the valve core cavity are connected in sequence.

[0055] Specifically, the gas flow path is as follows:

[0056] After the gas enters through the first valve body inlet 101, it enters the solenoid valve cavity through the solenoid valve inlet 191, and then enters the rear cover cavity 181 through the solenoid valve cavity outlet 192. When the valve core 130 drives the flow regulating plate 140 to rotate at different angles, the flow regulating hole 141 of the corresponding diameter is connected to the second valve body inlet 102. The gas enters the valve core guide groove 131 through the second valve body inlet 102, and finally flows into the main flame channel 110 and the secondary flame channel 120, realizing precise control of the flame size of the dual channels.

[0057] In addition, a sealing angle is formed between the second valve body air inlet 102 and the valve core air guide groove 131. Only when the valve core 130 is rotated to a certain angle will the second valve body air inlet 102 and the valve core air guide groove 131 be connected, which plays the role of connecting and closing the main air intake.

[0058] Preferably, a sealing gasket 200 is provided between the flow regulating plate 140 and the valve body 100. The sealing gasket 200 has a through hole for the flow regulating hole 141 to communicate with the air inlet hole 102 of the second valve body. As the flow regulating plate 140 rotates, the conduction area between the flow regulating hole 141 and the air inlet of the second valve body 100 is changed, so as to change the amount of air entering the valve core cavity.

[0059] Furthermore, a first spring 210 is provided between the flow regulating plate 140 and the rear cover 180. The first spring 210 presses the flow regulating plate 140 and the sealing gasket 200 onto the valve body 100. The sealing gasket 200 makes the valve body 100 and the flow regulating plate 140 seal each other to prevent flow exchange and ensure that the gas can only enter through the flow regulating hole 141 and then along the second valve body air inlet hole 102.

[0060] Preferably, the valve core 130 also has a spring cavity 132, in which a second spring 133 is installed, and the two ends of the second spring 133 abut against the valve core 130 and the valve core coupling 160, respectively.

[0061] The second spring 133 positions the valve core 130 within the valve core cavity and automatically eliminates the gap between the conical plug and the valve body 100 caused by damage. It also ensures that the spring force applied to the valve core 130 will not cause the valve core 130 to lift off the valve core cavity or move to a position that could lead to gas leakage.

[0062] In addition, the flow regulating holes 141 on the flow regulating plate 140 can be configured as multiple independent air holes, or fan-shaped holes, or other shapes.

[0063] Example 2

[0064] like Figure 7 As shown, the difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 integrates dampers 220 at the outlets of the main fire channel 110 and the fire outlet channel 120. By integrating the dampers 220 onto the valve body, they can be directly connected to the burner head without the need for additional accessories, making installation simpler and more convenient, and saving costs.

The above are specific embodiments of this utility model. 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.

[0066] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0067] Furthermore, in this utility model, descriptions involving "", "a", "one", etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "" or "a" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0068] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0069] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
