Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Examples:

as shown in fig. 2 to 6, the valve assembly provided in this embodiment includes an air inlet pipe 4, a valve body 5, a valve core structure and an electric control structure 7; the air inlet pipe 4 is provided with an air outlet 40, an air channel 50 is formed in the valve body 5, and two ends of the air channel 50 are communicated to the side wall of the valve body 5 and respectively form an inlet 51 and an outlet 52; the valve body 5 is arranged on one side of the air inlet pipe 4, the inlet 51 is in butt joint communication with the air outlet 40, and the outlet 52 is used for being in butt joint communication with the air inlet 20 of the combustor 2; the valve core structure is arranged in the gas channel 50, the electric control structure 7 is connected with the valve core structure, and the electric control structure 7 is used for controlling the valve core structure to be opened and closed and adjusting the opening degree of the valve core structure.

In the valve assembly provided in this embodiment, the air inlet pipe 4 may also be provided with an air supply port, for example, one end pipe orifice of the air inlet pipe 4 is used as an air supply port, and the air supply port is used for being in butt joint communication with the end of the main air supply pipe of the gas stove. In the use process, after the air supply port is in butt joint communication with the tail end of the main air supply pipe of the gas stove in a plugging mode or a flange connection mode, the outlet 52 of the valve body 5 in the valve assembly can be in butt joint communication with the air inlet 20 of the burner 2 in the gas stove, the air inlet 20 of the burner 2 is the pipe orifice of the injection pipe of the burner 2, if the injection pipe is multiple, the number of the outlets 52 arranged on the valve body 5 can also be multiple, and the outlets 52 are in one-to-one butt joint communication with the injection pipes.

It can be seen that the valve body 5 in the valve assembly is mutually matched with the air inlet pipe 4 to realize the communication between the total air supply pipe of the gas stove and the injection pipe of the burner 2 in the gas stove, and the valve core structure in the air channel 50 in the valve body 5 and the electric control structure 7 are mutually matched to replace the electric control valve 1 adopted on the existing gas stove, so compared with the existing gas stove, the valve assembly provided by the embodiment can realize the sequential communication of the total air supply pipe of the gas stove, the electric control valve 1 and the injection pipe of the burner 2 by the butt joint communication of the air inlet pipe 4 and the total air supply pipe of the gas stove and the butt joint communication of the outlet 52 of the valve body 5 and the air inlet 20 (injection pipe) of the burner 2, thereby avoiding the additional arrangement of the aluminum pipe 3 between the electric control valve 1 and the injection pipe of the burner 2.

When the gas range is turned on, the gas can flow to the gas inlet pipe 4 in the valve assembly through the main gas supply pipe of the gas range, and as shown in fig. 3 and 4, the gas in the gas inlet pipe 4 can continue to flow to the gas channel 50 inside the valve body 5 due to the abutting communication between the inlet 51 of the valve body 5 and the gas outlet 40 of the gas inlet pipe 4. As shown in fig. 2, the outlet 52 of the valve body 5 is in abutting communication with the air inlet 20 (ejector pipe) of the burner 2, so that the fuel gas flowing into the gas channel 50 can further flow to the air inlet 20 (ejector pipe) of the burner 2.

It should be noted that, a valve core structure is disposed in the gas channel 50, and the valve core structure can realize on-off of the gas channel 50 and adjustment of the gas flow in the gas channel 50 under the control of the electric control structure 7. Specifically, when the gas needs to be supplied to the gas inlet 20 of the burner 2, a communication instruction can be sent to the electric control structure 7, and then the electric control structure 7 can control the valve core structure to be opened, so that the gas channel 50 is communicated; when it is necessary to prevent the supply of fuel gas to the inlet 20 of the burner 2, a blocking command may be sent to the electronic control structure 7, and then the electronic control structure 7 controls the valve core structure to be closed, so that the gas channel 50 is blocked. In addition, when the gas flow at the gas inlet 20 of the burner 2 needs to be adjusted, a gas adjustment command may be sent to the electronic control structure 7, and then the electronic control structure 7 may adjust the opening of the valve core structure to adjust the flow area of the gas channel 50, thereby realizing the gas flow adjustment at the gas inlet 20 of the burner 2.

Compared with the prior art, the valve assembly provided by the embodiment integrates the air inlet pipe 4, the valve core structure and the electric control structure 7 on the valve body 5, and the outlet 52 of the valve body 5 is in butt joint communication with the air inlet 20 of the burner 2 of the gas stove and the air inlet pipe 4 is in butt joint communication with the main air supply pipe of the gas stove, so that the communication between the main air supply pipe and the burner 2 can be realized, the air supply process can be controlled, a large number of aluminum pipes 3 are not required, the assembly is simplified, and the hidden danger of air leakage is reduced.

It should be noted that, the valve assembly provided in this embodiment not only can realize the communication between the main air supply pipe and the burner 2 injection pipe of the gas stove through the valve body 5 integrated with the air inlet pipe 4, the valve core structure and the electric control structure 7, thereby omitting the aluminum pipe 3 between the electric control valve 1 and the burner 2 injection pipe of the existing gas stove, and the valve body 5 can be directly installed in the space between the main air supply pipe and the burner 2 injection pipe of the gas stove, thereby fully utilizing the installation space of the original electric control valve 1 and the aluminum pipe 3, and not occupying more space.

As shown in fig. 5 and 6, the outlet 52 of the valve body 5 is provided with a nozzle 8, and as shown in fig. 2, the nozzle 8 is used for being inserted into the air inlet 20 of the burner 2.

The nozzle 8 is used for realizing plug-in connection between the outlet 52 of the valve body 5 and the air inlet 20 of the burner 2 inside the gas stove, and specifically, when the air inlet 20 of the burner 2 needs to be communicated with the outlet 52 of the valve body 5, the nozzle 8 is directly plugged into an injection pipe of the burner 2.

It can be seen that the nozzle 8 can simplify the process of abutting communication between the outlet 52 of the valve body 5 and the inlet 20 of the burner 2, thereby simplifying the gas range installation process and improving the convenience of use of the valve assembly.

In this embodiment, to ensure the mounting stability of the nozzle 8, the nozzle 8 may be fixed in the outlet 52 of the valve body 5 by screw-fitting.

In practical application, the air inlets 20 (ejector pipes) of the burner 2 are usually multiple, and the multiple ejector pipes are distributed at intervals, corresponding to the air inlets, the outlets 52 of the valve body 5 can also be multiple, the nozzles 8 are fixed at the multiple outlets 52, the multiple nozzles 8 are distributed at intervals, at the moment, the accurate one-to-one correspondence communication between the multiple nozzles 8 and the multiple ejector pipes can be ensured by controlling the interval between the nozzles 8 to be consistent with the interval between the ejector pipes.

As shown in fig. 6, the valve core structure includes an opening and closing valve core 60 and an opening valve core 61, and the electric control structure 7 includes an opening and closing electric controller 70 and an opening and closing electric controller 71; the opening/closing valve core 60 and the opening valve core 61 are provided in the gas passage 50, respectively, and the opening/closing valve core 60 is connected to the opening/closing electric controller 70, and the opening valve core 61 is connected to the opening/closing electric controller 71.

Wherein, the opening and closing valve core 60 and the opening valve core 61 can be arranged in the gas channel 50 at intervals, and in use, the opening and closing valve core 60 only has two working states of opening and closing under the control of the opening and closing electric controller 70.

The opening valve core 61 can move in the gas channel 50 under the control of the opening and closing electric controller 70 to adjust the flow area of the gas channel 50 where the opening valve core 61 is located, thereby realizing gas flow adjustment. Since the on-off of the gas passage 50 is achieved by the on-off valve core 60 and the on-off electric controller 70 being mutually matched, the opening valve core 61 is not required to completely block the gas passage 50 to achieve the blocking of the gas passage 50, and correspondingly, when the opening valve core 61 adjusts the flow area of the gas passage 50 to the minimum, the gas passage 50 at the opening valve core 61 is still in a communicating state.

In practical applications, the valve core structure may also only adopt the opening valve core 61, and at this time, the blocking of the gas channel 50 can be achieved by fully closing the opening valve core 61, and correspondingly, the electric control structure 7 may only include the opening and closing electric controller 70.

It should be noted that, when the blocking of the gas passage 50 is achieved by using only the opening valve element 61, the structure of the valve element structure is more complicated and the electric control process is complicated, so the valve element structure of the present embodiment preferably includes both the opening valve element 61 and the opening valve element 60.

It can be seen that the valve assembly provided in this embodiment controls the on-off and the opening of the gas channel 50 by using the on-off valve core 60 and the opening valve core 61, so that the on-off process and the opening adjustment process of the gas channel 50 are simplified at the same time, thereby effectively ensuring the convenience and safety of use of the valve assembly.

In practical applications, the structure of the opening/closing valve core 60 is selected from various kinds, such as ball valve, butterfly valve, gate valve, etc., and the structure of the opening valve core 61 is also selected from various kinds, such as regulating valve, throttle valve, etc.

In this embodiment, the on-off valve core 60 is preferably a valve core of an electromagnetic valve, the corresponding on-off electric controller 70 is an electromagnet, and the on-off valve core 60 and the on-off electric controller 70 adopt electromagnetic valves; in this embodiment, the opening valve core 61 is preferably a sleeve valve core, and the opening electric controller 71 is a motor correspondingly, and at this time, the opening valve core 61 and the opening electric controller 71 adopt sleeve type regulating valves.

When the opening/closing valve core 60 is a valve body of an electromagnetic valve, as shown in fig. 6, the opening/closing electric controller 70 may be provided outside the valve body 5, and the opening/closing electric controller 70 is connected to the opening/closing valve core 60; the side wall of the valve body 5 is provided with a through hole, and the on-off valve core 60 extends into the gas passage 50 after passing through the through hole. When the opening and closing electric controller 70 receives the communication instruction, the opening and closing electric controller 70 controls the opening and closing valve core 60 to move in the direction approaching the opening and closing electric controller 70 in the gas channel 50, so that the gas channel 50 is communicated; when the opening/closing electric controller 70 receives the blocking instruction, the opening/closing electric controller 70 controls the opening/closing valve core 60 to move in the direction away from the opening/closing electric controller 70 in the gas passage 50, thereby blocking the gas passage 50.

The opening/closing valve core 60 may be a sealing plug made of a sealing material such as rubber.

When the opening valve element 61 is a sleeve valve element, as shown in fig. 6, the opening electric controller 71 may be provided outside the valve body 5, and an output end of the opening electric controller 71 is connected to the opening valve element 61. In order to ensure the stability of the opening degree electric controller 71, the opening degree electric controller 71 may be fixedly connected to the outer wall of the valve body 5 by a fastener such as a screw.

At this time, as shown in fig. 7, 8 and 9, the gas channel 50 in the valve body 5 may include a main channel 500 and a branch channel 501, one end of the main channel 500 is an inlet 51, the other end of the main channel 500 penetrates through to the side wall of the valve body 5 to be used as a mounting hole, and as shown in fig. 6, the opening valve core 61 is sleeved in the main channel 500 after passing through the mounting hole; as shown in fig. 8, the side wall of the main channel 500 is further provided with a through hole 5000, the branch channel 501 shown in fig. 9 communicates the through hole 5000 with the outlet 52 provided on the side wall of the valve body 5, the side wall of the sleeve-type valve core is provided with a plurality of adjusting holes 610 distributed at intervals along the circumferential direction, the apertures of the plurality of adjusting holes 610 are not equal, the aperture of any adjusting hole 610 is not larger than the aperture of the through hole 5000, and any adjusting hole 610 of the plurality of adjusting holes 610 communicates with the through hole 5000.

When the opening electronic controller 71 receives the gas adjustment command, the opening electronic controller 71 controls the opening valve core 61 to rotate in the main channel 500 of the gas channel 50, so that the adjusting hole 610 corresponding to the gas adjustment command is communicated with the through hole 5000 to realize the adjustment of the overflow area of the gas channel 50 at the through hole 5000, and finally, the purpose of adjusting the gas flow is achieved.

Further, when the opening valve core 61 is a sleeve valve core, as shown in fig. 6 and 8, the opening valve core 61 may be tapered, and the main channel 500 is correspondingly tapered, and at this time, the opening valve core 61 and the main channel 500 are in tapered fit, and the tapered fit form may play a role in limiting the opening valve core 61, so as to prevent the opening valve core 61 from moving along the axial direction of the main channel 500 and being deviated during rotation.

In this embodiment, when there are a plurality of injection pipes of the burner 2, there are a plurality of outlets 52 on the valve body 5, and in order to achieve communication between each outlet 52 and the gas channel 50, as shown in fig. 8 and 9, there may be a plurality of through holes 5000 on the side wall of the main channel 500, one end of the plurality of branch channels 501 is in one-to-one communication with the plurality of through holes 5000, and the other end of the plurality of branch channels 501 is in one-to-one communication with the plurality of outlets 52.

In addition, the pipe diameters of the injection pipes of the burner 2 can be different, at the moment, part of the injection pipes are used as main injection pipes, and the other part of the injection pipes are used as auxiliary injection pipes; correspondingly, the apertures of the plurality of outlets 52 on the valve body 5 are correspondingly different, and the apertures of the plurality of through holes 5000 are correspondingly different.

As shown in fig. 6, 7 and 8, the valve body 5 includes a main valve body 53 and a cover plate 54, the inlet 51 and the outlet 52 are both provided on the main valve body 53, and a groove communicating the outlet 52 and the inlet 51 is provided on one side of the main valve body 53, and the cover plate 54 is fixed to the side of the main valve body 53 provided with the groove, the groove being used for forming the gas passage 50.

When the gas passage 50 includes the main passage 500 and the branch passage 501, the main passage 500 may be directly opened inside the main valve body 53, and the branch passage 501 is formed by combining the groove on the valve body 5 and the cover plate 54. It should be noted that, a space needs to be provided between the main channel 500 and the bottom of the groove to prevent the main channel 500 from directly communicating with the groove.

It can be seen that the cover plate 54 is used to mutually cooperate with the main valve body 53 to ensure the tightness of the branch passage 501 in the gas passage 50.

It should be noted that, in this embodiment, the gas channel 50 is divided into the total channel and the branch channel 501, and the grooves and the cover plate 54 are combined to form the branch channel 501, so that not only the valve core structure, the electric control structure 7 and the gas channel 50 can be integrated on the valve body 5, but also the space in the valve body 5 can be fully utilized, thereby reducing the volume of the valve body 5 to the maximum extent so as to reduce the space occupation of the valve assembly.

As shown in fig. 6, the valve assembly provided in this embodiment further includes a gasket 55, and the gasket 55 is fitted and fixed between the cover plate 54 and the main valve body 53.

The gasket 55 is used for sealing a gap between the main valve body 53 and the cover plate 54 to ensure tightness between the main valve body 53 and the cover plate 54, and further, a strip-shaped hole can be formed at a position of the gasket 55 corresponding to the groove, and the strip-shaped hole is communicated with the groove.

Further, as shown in fig. 9, a limiting groove 530 is further provided on the side of the main valve body 53 provided with the groove, and the sealing pad 55 is installed in the limiting groove 530.

The limiting groove 530 is used for limiting the sealing gasket 55 to prevent the sealing gasket 55 from deviating, and for further improving the installation stability of the sealing gasket 55, the main valve body 53, the sealing gasket 55 and the cover plate 54 can be sequentially and fixedly connected through fasteners such as screws.

At this time, the inner space of the first valve body 532 and the inner space of the second valve body 533 together form a total channel in the gas channel 50, and the groove for forming the branch channel 501 is formed in the second valve body 533, and the cover plate 54 is fixedly connected with the second valve body 533; the opening of the first valve body 532, which is far from the second valve body 533, is opened to serve as the inlet 51, and the opening/closing valve core 60 passes through the through hole formed in the first valve body 532 and then extends into the inner space of the first valve body 532.

In order to facilitate the opening and closing of the opening and closing valve core 60 to the gas passage 50, the first valve body 532 is preferably bent, and the through hole formed in the first valve body 532 for passing through the opening and closing valve core 60 is formed in a sidewall at a corner thereof.
