[0034] Reference Figure 1 , Figure 2 and Figure 3 A stackable gas valve includes a valve body 100, a valve core 200, a push piece 300 and a movable plug 400. The valve body 100 is provided with a valve core channel 110 and an outlet channel 120, a first channel 130 and a second channel 140 respectively connected to the valve core channel 110. The valve body 100 is provided with a first connecting portion 160 and a second connecting portion 170 corresponding to the first connecting portion 160. The first connecting portion 160 is located at the first channel 130, the second connecting portion 170 is located at the second channel 140, and the second connecting portion 170 is provided with a third channel 150 capable of being connected to the second channel 140. The valve core 200 is arranged in the valve core channel 110 and can make the valve core channel 110 and the second channel 140 communicate with each other. The air outlet channel 120 is connected or disconnected; the pushing member 300 is arranged on the first connecting portion 160 and is provided with an air inlet channel 310 connected to the first channel 130; the movable plug 400 is movably arranged on the second connecting portion 170 and is located between the second channel 140 and the third channel 150. The movable plug 400 can connect or disconnect the second channel 140 and the third channel 150. The two valve body main bodies 100 can be connected through the cooperation of the first connecting portion 160 on one of them and the second connecting portion 170 on the other, so that the pushing member 300 on one of them can push the movable plug 400 on the other to move, and the first channel 130 on one of them can be connected to the third channel 150 on the other.

[0035] When a single stackable gas valve is used, the first connection portion 160 of the valve body 100 is connected to a gas bottle, and the gas outlet channel 120 is connected to a gas device, such as Figure 4 and Figure 5 As shown, the movable plug 400 disconnects the second channel 140 from the third channel 150. When gas is supplied to the gas equipment, the valve core channel 110 is connected to the gas outlet channel 120 through the valve core 200, and the gas enters from the gas inlet channel 310 of the push member 300 and is output from the gas outlet channel 120 through the first channel 130 and the valve core channel 110. When the gas supply is turned off, the valve core channel 110 is disconnected from the gas outlet channel 120 through the valve core 200. When two stackable gas valves are stacked and connected for use, as shown in FIG. Figure 6 and Figure 7 As shown, the first connection part 160 on one of them is connected to the gas bottle, and the first connection part 160 on the other one is connected to the second connection part 170 on the one, and the push piece 300 on the other one pushes the movable plug 400 on the one to move, so that the second channel 140 on the one is connected with the third channel 150, and at the same time, the first channel 130 on the other one is connected with the third channel 150 on the one through its air intake channel 310, and the gas enters from the air intake channel 310 on the one, and sequentially passes through the first channel 130, the valve core channel 110, the second channel 140, and the third channel 150 on the one to enter the air intake channel 310, the first channel 130 and the valve core channel 110 on the other, and the two stackable gas valves both control the connection or disconnection of the valve core channel 110 and the gas outlet channel 120 through their respective valve cores 200, thereby controlling the opening and closing of the gas supply. The stackable gas valve of the present invention can be used alone to control the gas supply between a gas cylinder and a gas device, and can also be stacked and connected for use. Each stackable gas valve can independently control the opening and closing of the gas passage, so that the same gas cylinder can be used by multiple gas devices. When using it outside, the amount of gas cylinders to be carried can be reduced.

[0036] Of course, in actual application, in addition to the two stackable gas valves that can be stacked and connected for use, three or more stackable gas valves can also be stacked and connected in pairs to achieve the stackable connection of multiple stackable gas valves. The specific structure of the present invention can be changed according to actual needs, so it will not be described in detail here, and will be explained in detail below.

[0037] In some embodiments, the movable plug 400 is provided with an abutment boss 410 and an elastic member 420 connected to the abutment boss 410 . The elastic member 420 can make the abutment boss 410 abut against the second connecting portion 170 , and the abutment boss 410 can block the air inlet end of the third channel 150 . By providing the elastic member 420 and the abutting boss 410, when a single stackable gas valve is used, the abutting boss 410 abuts against the second connecting portion 170 under the action of the elastic member 420, thereby blocking the air inlet end of the third channel 150, disconnecting the second channel 140 from the third channel 150, and preventing gas leakage; when two stackable gas valves are used in a stacked connection, the pushing member 300 on one pushes the movable plug 400 on the other to move, compressing the elastic member 420 on the other, so that a gap exists between the abutting portion of the abutting boss 410 on the other and the second connecting portion 170, thereby achieving communication between the second channel 140 and the third channel 150 on the other, thereby achieving that the movable plug 400 can connect or disconnect the second channel 140 from the third channel 150, and the structure is simple, and it is easy to manufacture and use.

[0038] In this embodiment, if Figure 3 , Figure 4 and Figure 5 As shown, the movable plug 400 is arranged between the second channel 140 and the third channel 150, and the lower end of the movable plug 400 is provided with an abutment boss 410 protruding radially, and the abutment boss 410 is a truncated cone-shaped structure, and its maximum outer diameter is larger than the inner diameter of the third channel 150, so that when the abutment boss 410 abuts against the lower end of the second connecting part 170, it can block the air inlet end of the third channel 150, and the lower end of the second connecting part 170 is recessed upward to form a recessed position for the abutment boss 410 to be inserted, and the lower end of the abutment boss 410 is connected to the elastic member 420, and the elastic member 420 is a spring. The end surface of the air outlet end of the second channel 140 is recessed to form a recessed position for the elastic member 420 to be connected. In actual application, the movable plug 400 can not only connect or disconnect the second channel 140 and the third channel 150 by abutting the boss 410 and the elastic member 420, but also can realize it by setting an inclined wedge structure and a blocking block. The inclined wedge structure can convert the vertical up and down movement into the horizontal movement of the blocking block, thereby blocking the air inlet end of the third channel 150, so that the movable plug 400 can connect or disconnect the second channel 140 and the third channel 150. The specific structure of the movable plug 400 can be changed according to the actual use needs and is not limited here.

[0039] In some embodiments, a first sealing rubber ring 411 is provided at the abutting surface between the abutting boss 410 and the second connecting portion 170. By providing the first sealing rubber ring 411 at the abutting surface between the abutting boss 410 and the second connecting portion 170, when the abutting boss 410 abuts against the second connecting portion 170, the sealing between the two can be improved, further preventing gas leakage, and improving the safety of use.

[0040] In this embodiment, if Figure 5 As shown, the side of the abutting boss 410 is recessed to form a recessed groove for the first sealing rubber ring 411 to connect. The first sealing rubber ring 411 is clamped and fixed in the recessed groove, and when the abutting boss 410 abuts on the second connecting portion 170, the first sealing rubber ring 411 also abuts on the second connecting portion 170 to improve the sealing performance. In actual application, the first sealing rubber ring 411 can also be arranged on the second connecting portion 170 and located at the abutting surface or abutting edge thereon. The setting position and number of the first sealing rubber ring 411 can be set accordingly according to actual use needs, and are not limited here, and can be understood by those skilled in the art.

[0041] In some embodiments, the upper end of the movable plug 400 is movably inserted in the third channel 150 and has a gap with the wall of the third channel 150. By setting the upper end movably inserted in the third channel 150, the stability of the connection and movement of the movable plug 400 can be improved. At the same time, there is a gap between the upper end of the movable plug 400 and the wall of the third channel 150, which can facilitate the communication between the second channel 140 and the third channel 150, and when two stackable gas valves are stacked and connected for use, it can facilitate the communication between the first channel 130 on one and the third channel 150 on the other. The structure is simple, easy to manufacture and use, and convenient for the installation and connection of the movable plug 400.

[0042] In this embodiment, if Figure 4 and Figure 5 As shown, the upper end of the movable plug 400 is movably inserted in the third channel 150 and has a gap with the wall surface of the third channel 150. The upper end surface of the movable plug 400 is lower than the upper end surface of the second connecting portion 170, so as to prevent the movable plug 400 from being easily moved by accidental touch. When the movable plug 400 moves downward, the upper end of the movable plug 400 plays a certain guiding role. At the same time, a gap is formed between the abutting surface of the abutting boss 410 and the peripheral wall of the lower end recess of the second connecting portion 170, and the second channel 140 is connected with the third channel 150 through the peripheral wall gap of the abutting boss 410. In actual application, in addition to providing a gap between the upper end of the movable plug 400 and the wall of the third channel 150 so that the second channel 140 can be connected to the third channel 150, an "L"-shaped through groove structure can also be provided on the movable plug 400, the upper end of the "L"-shaped through groove is connected to the upper end surface of the movable plug 400, and the lower end thereof is connected to the corner of the abutting boss 410 on the movable plug 400, so that when the movable plug 400 moves downward, the "L"-shaped through groove can connect the gap on the abutting surface of the upper end of the movable plug 400 and the abutting boss 410. The specific structure of the movable plug 400 can be changed accordingly according to actual use needs, and is not limited here.

[0043] In some embodiments, a pushing part 320 is provided on the pushing member 300, and an air inlet hole 321 communicating with the air inlet channel 310 is provided on the peripheral wall of the pushing part 320, and the outer diameter of the pushing part 320 is smaller than the inner diameter of the third channel 150. By setting the outer diameter of the pushing part 320 smaller than the inner diameter of the third channel 150, when two stackable gas valves are stacked and connected for use, the pushing part 320 of one of the pushing members 300 can be inserted into the third channel 150 of the other, and the pushing part 320 of the one pushes the movable plug 400 of the other to move, and the air inlet hole 321 is provided on the peripheral wall of the pushing part 320, so that the air inlet channel 310 on the one can be communicated with the third channel 150 on the other through its air inlet hole 321, and then the third channel 150 on the other can be communicated with the first channel 130 on the one, so that the connection and air intake between the two stackable gas valves are convenient.

[0044] In this embodiment, if Figure 4 and Figure 7 As shown, the air inlet hole 321 is connected with the air inlet channel 310 to form a "cross" shaped channel. When two stackable gas valves are stacked and connected for use, the pushing portion 320 on the pushing member 300 of the upper stackable gas valve in the figure is inserted into the third channel 150 of the lower stackable gas valve, and pushes the movable plug 400 below to move, so that the second channel 140 of the lower stackable gas valve is connected with the third channel 150, and at the same time, the third channel 150 of the lower stackable gas valve is connected with the first channel 130 of the upper stackable gas valve through the air inlet hole 321 and the air inlet channel 310 on the pushing member 300 of the upper stackable gas valve. In actual application, the first channel 130 and the third channel 150 between the two stackable gas valves can be connected by the above structure. In addition, a push pin can be set on the push piece 300, and the air intake channel 310 is set near the push pin. When the two stackable gas valves are stacked and connected for use, the air intake channel 310 on the upper stackable gas valve is directly connected to the third channel 150 on the lower stackable gas valve, thereby realizing the connection between the first channel 130 and the third channel 150 between the stackable gas valves. The specific structure of the push piece 300 can be changed accordingly according to actual use needs, and is not limited here.

[0045] In some embodiments, a second sealing rubber ring 151 is provided at the gas outlet end of the third channel 150. By providing the second sealing rubber ring 151 at the gas outlet end of the third channel 150, when two stackable gas valves are stacked and connected for use, when the push portion 320 of the push member 300 on one is inserted into the third channel 150 on the other, the sealing between the push portion 320 and the gas outlet end of the third channel 150 can be improved, further preventing gas leakage, and improving the safety of use.

[0046] In this embodiment, if Figure 4 and Figure 7 As shown, a second sealing rubber ring 151 is provided at the gas outlet end of the third channel 150. When two stackable gas valves are stacked and connected for use, the push portion 320 on one is inserted into the third channel 150 on the other, and the second sealing rubber ring 151 is squeezed to seal the gap between the two to improve the sealing performance. In actual application, the setting position and number of the second sealing rubber ring 151 can be set accordingly according to actual use needs, and are not limited here, and can be understood by those skilled in the art.

[0047] In some embodiments, when two valve bodies 100 are connected, the first connection portion 160 on one of them can be connected to the second connection portion 170 on the other through a thread. By setting the second connection portion 170 and the first connection portion 160 to be threadedly connected, the two stackable gas valves can be stacked and connected through the threaded connection of the second connection portion 170 on one of them and the first connection portion 160 on the other, thereby realizing a stackable connection between the two stackable gas valves, which is convenient to connect and disassemble, has good connection stability, is simple in structure, and is easy to manufacture.

[0048] In this embodiment, if Figure 4 , Figure 6 and Figure 7 As shown, the first connection part 160 and the second connection part 170 can be connected to the valve body 100 by means of threads or interference fit, and a threaded structure (not shown in the figure) for connection is provided at the connection surface of the second connection part 170 and the first connection part 160. When two stackable gas valves can be stacked, the first connection part 160 of the stackable gas valve on the upper side and the second connection part 170 of the stackable gas valve on the lower side are fixed by threaded connection to realize the stackable connection between the two stackable gas valves.
