The valve core 200 is rotatably matched in the accommodating cavity 101, the valve core 200 is provided with a gas distribution cavity 201 and a gas passing hole 210 communicated with the gas distribution cavity 201, the gas inlet channel 110 is communicated with the gas distribution cavity 201, the gas passing hole 210 is selectively communicated with the first vent hole 121 and/or the second vent hole 131 when the valve core 200 rotates, and the gas passing hole is always communicated with the first gas outlet channel 120 and/or the second gas outlet channel 130 when the valve core 200 rotates.

It should be understood herein that the "the vent hole 210 is selectively communicated with the first vent hole 121 and/or the second vent hole 131 when the valve core 200 rotates" means that the vent hole 210 may be communicated with the first vent hole 121, or the vent hole 210 may be communicated with the second vent hole 131, or the vent hole 210 may be communicated with both the first vent hole 121 and the second vent hole 131 during the rotation of the valve core 200.

For example, the gas valve 1 is a valve structure for manually adjusting and controlling the on-off of gas and adjusting the gas flow, and the gas valve 1 includes a valve body 100, a valve core 200, a valve rod, a micro switch, an electromagnetic valve, and other additional devices. Specifically, the gas valve 1 can be a gas plug valve, and the main working principle is as follows: the gas of the gas source enters the gas valve 1 through the gas inlet channel 110 of the valve body 100, sequentially passes through the electromagnetic valve, then enters the valve core 200, and finally passes through the gas passing hole 210 of the valve core 200 to be communicated with the first gas outlet channel 120 and/or the second gas outlet channel 130, so that the gas is provided for the burner of the gas stove through the gas outlet channel.

According to the utility model discloses gas valve 1, through setting up valve body 100 and case 200, make case 200 rotationally cooperate in the holding chamber 101 of valve body 100. Thus, the gas supply amount of the gas stove can be adjusted by rotating the valve core 200, so that the firepower of the burner of the gas stove can be adjusted conveniently.

Moreover, the gas passing hole 210 is selectively communicated with the first vent hole 121 and/or the second vent hole 131 when the valve core 200 rotates, so that when the valve core 200 rotates to enable the gas passing hole 210 to be communicated with the first vent hole 121, gas can flow to an inner ring gas channel of the gas stove burner through the first gas outlet channel 120, and the gas can be combusted at the inner ring gas channel of the gas stove burner; when the valve core 200 is rotated to communicate the air passing hole 210 with the second air passing hole 131, the gas can flow to the outer ring gas channel of the gas stove head through the second air outlet channel 130, so that the gas can be combusted at the outer ring gas channel of the gas stove head; when the valve core 200 is rotated to communicate the air vent 210 with the first air vent 121 and the second air vent 131, the gas may flow to the inner ring gas channel of the gas stove head through the first air outlet channel 120 and to the outer ring gas channel of the gas stove head through the second air outlet channel 130, respectively, so that the gas may be combusted in the inner ring gas channel and the outer ring gas channel of the gas stove head.

Therefore, the air vent 210 can be communicated with both the first vent hole 121 and the second vent hole 131, and compared with the mode that the air vent of the first vent hole 121 and the air vent of the second vent hole 131 are independently arranged on the valve core 200, the air vent 210 can be conveniently processed and arranged, the air vent 210 can be conveniently arranged into any required shape, and the air vent 210 can have enough sealing distance around the air vent 210. Therefore, reasonable utilization of the space of the gas valve 1 is facilitated, the thickness of the valve body 100 is made to be very thin, the overall height of the gas valve 1 is reduced, the flow curve of the gas valve 1 can be made to be more linear, the fire adjusting performance of the inner ring and the outer ring of the burner of the gas stove is better, the rotating adjusting angle of the valve core 200 is convenient to increase, and a user can capture desired fire more easily when the gas stove is used.

In addition, the air hole 210 is always communicated with the first air outlet channel 120 and/or the second air outlet channel 130 when the valve core 200 rotates. Therefore, in the process of adjusting firepower, the firepower of the gas stove can be ensured to be continuous and not to be flameout. From this, be convenient for improve the firepower stability and the reliability of gas-cooker, avoid appearing flame-out phenomenon at the in-process of adjusting the firepower, avoid the user to need the secondary to strike sparks in the use, be convenient for improve user's use travelling comfort and convenience.

It should be understood that "the gas passing hole 210 is always communicated with the first gas outlet channel 120 and/or the second gas outlet channel 130 when the valve core 200 rotates" means that the gas passing hole 210 is always communicated with at least one of the first gas outlet channel 120 and the second gas outlet channel 130 during the rotation of the valve core 200, in other words, the gas stove burner is always in a state of burning gas.

A gas valve 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

In some embodiments of the present invention, as shown in fig. 1 to 16, a gas valve 1 according to an embodiment of the present invention includes a valve body 100 and a valve cartridge 200.

Specifically, the air passing hole 210 comprises a first air passing hole 211 and a second air passing hole 212 which are arranged at intervals, the first air passing hole 211 is suitable for being communicated with the first vent hole 121, the second air passing hole 212 is suitable for being communicated with the first vent hole 121 and the second vent hole 131, and the gas valve 1 has a first working state, a second working state and a third working state. In the first operating state, the first air passing holes 211 are communicated with the first air outlet channel 120 and the second air passing holes 212 are disconnected from the first air outlet channel 120 and the second air outlet channel 130. In the second operating state, the first air passing holes 211 are communicated with the first air outlet channel 120 and the second air passing holes 212 are communicated with the second air outlet channel 130. In the third operating state, the second air passing holes 212 are communicated with the first air outlet channels 120 and the first air passing holes 211 are disconnected from the first air outlet channels 120. Therefore, the gas flow of the gas valve 1 can be adjusted by changing the communication state of the gas passing hole 210 with the first gas outlet channel 120 and the second gas outlet channel 130, so as to adjust the fire power of the gas stove.

Alternatively, during rotation of the valve spool 200, the gas valve 1 undergoes the first operating state, the second operating state, and the third operating state in sequence.

More specifically, the gas valve 1 also has a fourth operating state in which the second porous hole 212 communicates with the first outlet passage 120 and the second outlet passage 130. Thus, the firepower of the gas stove can be adjusted conveniently, and the gas stove can have the maximum firepower under the fourth working state conveniently.

Optionally, in the process that the valve core 200 rotates, the gas valve 1 is sequentially switched among the first working state, the second working state and the third working state, and the gas output of the gas valve 1 shows a trend of increasing first and then decreasing.

In some embodiments, the air passing holes 210 further include a third air passing hole 213, the third air passing hole 213 is adapted to communicate with the first air passing hole 121, and a flow area of the third air passing hole 213 is smaller than a flow area of the first air passing hole 211 and smaller than a flow area of the second air passing hole 212. The gas valve 1 further has a fifth operating state in which the third air passing hole 213 communicates with the first air outlet passage 120. Specifically, the third air passing hole 213 may be formed as a minute fire hole. Therefore, the small fire adjustment of the gas stove is convenient to realize, and the fire adjustment range of the gas stove is convenient to enlarge.

Optionally, in the process that the valve core 200 rotates, the gas valve 1 is sequentially switched among the first working state, the second working state, the fourth working state, the third working state and the fifth working state, the gas output of the gas valve 1 has a trend of increasing first and then decreasing, the maximum fire occurs in the fourth working state, and the minimum fire occurs in the fifth working state.

The specific structure of the gas valve according to some embodiments of the present invention is described below.

Specifically, as shown in fig. 15, the air passing hole 210 includes an inner hole section 214 and an outer hole section 215 which are communicated with each other in the radial direction of the valve element 200, and the span of the outer hole section 215 in the circumferential direction of the valve element 200 is larger than the span of the inner hole section 214 in the circumferential direction of the valve element 200. The outer hole section 215 with a larger circumferential span along the valve core 200 can increase the maximum rotation angle of the valve core 200 for rotating and adjusting the flow, and the inner hole section 214 with a smaller circumferential span along the valve core 200 is matched with the outer hole section 215 with a larger circumferential span along the valve core 200 to improve the linear transformation of flow adjustment and the continuity of flow change. This facilitates changing the fitting area of the air vent 210 and the first air vent 121 and/or the second air vent 131 during the rotation of the valve core 200 to change the flow area of the gas, so as to adjust the amount of the gas supplied, and make the flow curve of the gas valve 1 more linear.

Specifically, the inner bore section 214 may be a circular hole, and the outer bore section 215 may be a kidney-circular hole extending in the circumferential direction of the spool 200. The round hole and the oval hole are easier to process, and the oval hole extending along the circumferential direction of the valve core 200 is easier to control the maximum rotation angle of flow regulation.

Alternatively, the valve cartridge 200 may be rotated through an angle in the range of 0-225 degrees. The valve body 200 can rotate in the range of 0 to 225 degrees by allowing the air passing hole 210 to communicate with the first air passing hole 121 and the second air passing hole 131, so that the rotation range of the valve body 200 can be enlarged, and the heating power of the gas stove burner can be adjusted more finely to capture the heating power desired by the user.

Of course, the valve cartridge 200 may be rotated through an angle of 180 degrees, 220 degrees, or 225 degrees.

In some embodiments, as shown in fig. 15, the air passing holes 210 include a first air passing hole 211, a second air passing hole 212 and a third air passing hole 213 which are arranged at intervals, the first air passing hole 211 is adapted to be communicated with the first air passing hole 121, the second air passing hole 212 is adapted to be communicated with the first air passing hole 121 and the second air passing hole 131, and the third air passing hole 213 is adapted to be communicated with the first air passing hole 121. Therefore, the valve core 200 can be communicated with the inner ring gas channel of the gas stove burner through the first air passing hole 211, the second air passing hole 212 and the third air passing hole 213, and is communicated with the outer ring gas channel of the gas stove burner through the second air passing hole 212, so that the fire can be conveniently switched and adjusted between the inner ring and the outer ring of the gas stove burner.

Specifically, as shown in fig. 15, the first air passing hole 211 and the third air passing hole 213 have a height higher than that of the second air passing hole 212 in the axial direction of the valve body 200 (the vertical direction is shown by an arrow a in fig. 15). Therefore, the second air passing hole 212, the first air passing hole 211 and the third air passing hole 213 can be arranged in a staggered mode, the shapes of the first air passing hole 211, the second air passing hole 212 and the third air passing hole 213 can be designed and processed conveniently, and the first air passing hole 211, the second air passing hole 212 and the third air passing hole 213 can be guaranteed to have enough sealing distance.

Alternatively, as shown in fig. 15, the first air passing hole 211, the second air passing hole 212 and the third air passing hole 213 are disposed adjacent to each other in the circumferential direction of the valve body 200, and the second air passing hole 212 is located between the first air passing hole 211 and the third air passing hole 213. This facilitates continuous variation of the fire power during rotation of the spool 200.

Specifically, as shown in fig. 6, the first vent hole 121 includes a first opening portion 122 and a second opening portion 123 which are communicated with each other in sequence in the extending direction of the accommodating chamber 101, the first opening portion 122 is adapted to be directly communicated with the first air passing hole 211 or the third air passing hole 213, and the second opening portion 123 is adapted to be directly communicated with the second air passing hole 212 or the third air passing hole 213. Since the first air passing hole 211 and the third air passing hole 213 are higher than the second air passing hole 212, the first opening portion 122 and the second opening portion 123 may be respectively corresponding to the first air passing hole 211, the second air passing hole 212 and the third air passing hole 213, so as to achieve reliable communication between the first air passing hole 121 and the first air passing hole 211, the second air passing hole 212 and the third air passing hole 213 during rotation of the valve core 200, and adjust the flow rate of the fuel gas.

Alternatively, as shown in fig. 6, the first vent hole 121 is provided in a side wall of the accommodating chamber 101, and the first vent hole 121 is provided obliquely in a thickness direction of the side wall of the accommodating chamber 101. This facilitates the rational arrangement of the air vent 210 and the first air outlet passage 120, and facilitates the rational and compact structure of the gas valve 1.

Specifically, in the circumferential direction of the accommodating chamber 101, the second vent hole 131 is located at an angle smaller than or equal to 90 degrees with the first vent hole 121, and in the axial direction of the accommodating chamber 101, the height of the first vent hole 121 is higher than that of the second vent hole 131. Specifically, the second vent hole 131 may be located within a range of 90 degrees rotated clockwise from the first vent hole 121. This facilitates the second vent hole 131 to be in fit communication with the second vent hole 212.

In some embodiments, as shown in fig. 1, the inlet of inlet channel 110, the outlet of first outlet channel 120 and the outlet of second outlet channel 130 are opened in the same direction, and the center lines of inlet channel 110, first outlet channel 120 and second outlet channel 130 are located in the same plane. Therefore, the length of the gas distribution pipe is reduced, the structure of the gas stove is more reasonable and compact, and the assembly performance of the gas stove is improved.

Alternatively, as shown in fig. 16, the valve body 100 further includes an air reservoir 140, and the air reservoir 140 communicates between the intake passage 110 and the accommodating chamber 101. Thus, the air storage chamber 140 has a pressure stabilizing function, so that the air outlet pressure of the gas valve 1 is more stable and does not change along with the change of the inlet pressure.

Further, the air receiver 140 is provided with a guide slope 141 adapted to guide the gas flowing into the gas separation chamber 201. Therefore, the guide slope 141 in the air receiver 140, on one hand, leaves a certain margin for the screw hole, and on the other hand, has the advantages of easy demolding, smaller resistance of the guide slope to gas, and smaller pressure loss of gas.

Specifically, the thickness of the valve body 100 is less than or equal to 18 millimeters. Therefore, not only is the material cost of the gas valve 1 saved, but also the installation and the arrangement of the gas valve 1 are facilitated.

Specifically, the gas valve 1 uses the second air passing hole 212 of the valve core 200 to give out air through the second air outlet channel 130 of the valve body 100, and the first air passing hole 211, the second air passing hole 212 and the third air passing hole 213 are arranged in a staggered manner in the axial direction of the valve core 200, so that the reasonable utilization of space is realized, the overall height of the gas valve 1 is reduced, the thickness of the valve body 100 can be very thin, the thinnest thickness is the diameter of a standard electromagnetic valve plus a certain wall thickness, namely the limit thickness of the valve body 100, and can be 18 mm.

In some embodiments, as shown in fig. 2 and 3, the rotation angle of the valve core 200 is 0 degree, that is, the valve core 200 does not rotate, and at this time, the first air outlet channel 120 and the second air outlet channel 130 are both in the off state, and no gas passes through; as shown in fig. 4-6, the rotation angle of the valve core 200 is 40 degrees, the first air outlet channel 120 is exhausted, and the second air outlet channel 130 is still in a disconnected state; as shown in fig. 7 and 8, the rotation angle of the valve core 200 is 90 degrees, and at this time, the gas valve 1 is at a large fire position, that is, the fire power of the gas valve 1 is the largest, and both the first gas outlet channel 120 and the second gas outlet channel 130 are communicated with the valve core 200 for gas outlet; as shown in fig. 9-11, the rotation angle of the valve core 200 is 170 degrees, at this time, the first air outlet channel 120 is in an air outlet state, and the second air outlet channel 130 is in a disconnected state; as shown in fig. 12-14, the rotation angle of the gas valve 1 is 225 degrees, and at this time, the gas valve 1 is at a low fire position, i.e. the fire power of the gas valve 1 is the minimum, only the first air outlet channel 120 is left to discharge air, and the fire power of the minimum fire is determined by the micro-fire aperture of the third air vent 213. Of course, the angle of the small fire position is not fixed, and can be set arbitrarily, for example, the rotation angle of the gas valve 1 can be 225 degrees, and the rotation angle of the gas valve 1 can also be 220 degrees.

Specifically, the valve rod of the gas valve 1 is rotated to drive the valve core 200 to rotate, first, the first air passing hole 211 on the valve core 200 is connected with the first air passing hole 121 on the valve body 100 to give out air, then, the valve core 200 is continuously rotated, and the second air passing hole 212 on the valve core 200 is connected with the second air passing hole 131 on the valve body 100 to give out air. When the first air passing hole 211 on the valve core 200 and the first vent hole 121 on the valve body 100 are staggered immediately, the second air passing hole 212 on the valve core 200 is connected with the first vent hole 121 on the valve body 100 to give out air, so that the function of fire receiving is realized, and at the moment, the first air outlet channel 120 and the second air outlet channel 130 on the valve body 100 both have gas to come out. Then, the valve core 200 is continuously rotated, the second air passing hole 212 on the valve core 200 is disconnected with the second air passing hole 131 on the valve body 100, the outer ring gas channel of the gas stove burner is closed, and only the inner ring gas channel is left for providing gas combustion and ignition. At this time, the third air passing holes 213 may be formed as the minute flame holes in the second air passing holes 131 of the valve body 100 by the third air passing holes 213 or without the third air passing holes 213. If the third air passing hole 213 is used, the air outlet range of the second air outlet channel 130 can be extended, and if the third air passing hole 213 is not used, the fire range of the outer ring gas channel is reduced, both schemes are possible. Then, the valve core 200 is rotated continuously, and when the second venting hole 212 of the valve core 200 is about to be disconnected from the first venting hole 121 of the valve body 100, the first venting hole 121 is connected to the third venting hole 213 (i.e. a micro-fire hole) of the valve core 200 again, so that fire is connected and the minimum fire is achieved.
