Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a natural gas valve, including the first in command 1, dwang 2 and main part 3, the one end swing joint of main part 3 has connecting pipe 12, the one end swing joint of connecting pipe 12 has connecting plate 13, the one end swing joint of connecting plate 13 has first fly leaf 5, the one end swing joint of first fly leaf 5 has natural gas pipe 6, first standing groove 11 has been seted up to the inside of connecting plate 13, the inside fixedly connected with third connecting block 10 of the other end of first fly leaf 5, the one end swing joint of third connecting block 10 has second connecting block 9, the one end swing joint of second connecting block 9 has first spring 8, the one end swing joint of first spring 8 has first connecting block 7, the one end swing joint of first connecting block 7 has button 4.

In this embodiment, due to long-term use, the main body 3 will be damaged to a certain extent, and the main body 3 needs to be replaced periodically, so as to facilitate normal use, when the main body 3 needs to be replaced, firstly, the first connecting block 7 is driven to move by applying a left pulling force to the button 4, then, under the action of the movement of the first connecting block 7, the first spring 8 is stretched to a certain extent and continues to move, due to the elastic force of the first spring 8, the second connecting block 9 is driven to start to move towards the direction far away from one end of the connecting plate 13, secondly, due to the attachment connection of the other end of the third connecting block 10 and the inner wall of the other end of the first movable plate 5, under the action of the movement of the second connecting block 9, the third connecting block 10 is driven to start to move, that is, the first movable plate 5 starts to move towards the direction far away from one end of the connecting plate 13, until the other end of the first movable plate 5 is completely separated from one end of the connecting plate 13, at this time, the button 4 is stopped to be pulled, the main body 3 is not limited, and can be taken out for replacement, and after the replacement is finished, the main body 3 can be fixed by reverse operation, because the first movable plate 5 is internally provided with a through hole matched with the natural gas pipe 6, and the connecting plate 13 is internally provided with a round hole matched with the connecting pipe 12, when the other end of the first movable plate 5 is jointed and connected with one end of the connecting plate 13, natural gas can smoothly reach the interior of the natural gas pipe 6 from one end of the connecting pipe 12 through the first movable plate 5 and the interior of the connecting plate 13, thereby avoiding the direct connection between the connecting pipe 12 and the natural gas pipe 6, when the main body 3 is replaced regularly, the connection between the connecting pipe 12 and the natural gas pipe 6 is easy to loosen, and natural gas leakage is caused, a danger arises.

Specifically, the bottom fixedly connected with fixed plate 20 of main part 3, the top swing joint of fixed plate 20 has movable block 15, the top fixedly connected with dead lever 19 of movable block 15, the top swing joint of dead lever 19 has first fixed block 18, the one end swing joint of first fixed block 18 has connecting rod 17, the surface swing joint of connecting rod 17 has second spring 16, the one end swing joint of second spring 16 has second fly leaf 14, second standing groove 23 has been seted up to the inside of the other end of dwang 2, the top fixedly connected with second fixed block 21 of main part 3, the bottom fixedly connected with third fixed block 22 of second fixed block 21, the other end swing joint of second fixed block 21 has movable rod 24, the other end swing joint of movable rod 24 has second handle 26, the surface swing joint of movable rod 24 has third spring 25.

In this embodiment, since the natural gas is required to adjust the flow rate of the natural gas according to the actual situation in the using process, so as to be better used, when the natural gas flow rate needs to be reduced, first, the first handle 1 is rotated to drive the rotating rod 2 to start moving in the direction close to the bottom of the main body 3 until the natural gas flow rate is properly adjusted, the rotating rod 2 is stopped to rotate, then, an external force is applied to the second handle 26 to drive the movable rod 24 to start moving in the direction close to the outer surface of the rotating rod 2, at this time, the third spring 25 is compressed to a certain degree until one end of the movable rod 24 moves into the second accommodating groove 23, at this time, the external force is stopped to be applied to the second handle 26, the movement position of the rotating rod 2 is fixed, that is, the position of the movable block 15 is fixed, because the sliding groove matched with the connecting rod 17 is formed inside the other end of the second movable plate 14, the other end of the second flap 14 is attached to one end of the second spring 16, when natural gas enters from the other end of the main body 3, a certain air pressure is generated, and the air pressure will make the second flap 14 move in a direction away from one end of the movable block 15 until the other end of the second flap 14 is completely separated from one end of the connecting rod 17 and one end of the movable block 15, at which time, the second spring 16 is stretched to a certain degree, so that the natural gas can smoothly pass through the inside of the main body 3, if the natural gas leaks, the gas pressure generated by the natural gas is not enough to drive the second movable plate 14 to move in the direction away from one end of the connecting rod 17, at this time, the other end of the second movable plate 14 is attached and connected with the connecting rod 17, thereby avoided using under the unknown natural gas leakage's the condition, caused danger, if need increase natural gas flow, reverse operation can.

Specifically, the sectional shape of the first placing groove 11 is a circle, and the diameter of the inner surface of the first placing groove 11 is equal to one point and one time of the diameter of the outer surface of the other end of the first flap 5.

In this embodiment, the other end of the first flap 5 is facilitated to move inside the first placing groove 11, so that the first flap 5 is stably connected with the connecting plate 13.

Specifically, a round hole matched with the outer surface of the button 4 is formed in one end of the first movable plate 5, and a clamping groove matched with the button 4 is formed in one end of the first connecting block 7.

In the present embodiment, the movement of the button 4 inside one end of the first flap 5 is facilitated; the button 4 is convenient to be connected with the first connecting block 7 better, so that when the button 4 moves, the first connecting block 7 can be driven to move.

Specifically, the top of the movable block 15 is provided with a connecting groove matched with the bottom of the rotating rod 2, and the top of the movable block 15 is provided with a groove matched with the fixed rod 19.

In this embodiment, the movable block 15 is conveniently connected to the rotating rod 2, so that the rotating rod 2 drives the movable block 15 to move up and down; so that the movable block 15 and the fixed rod 19 are more stably connected.

Specifically, the number of the movable blocks 15 is two, and the two movable blocks 15 are respectively located inside the main body 3.

In this embodiment, through setting up two movable blocks 15, be convenient for adjust the flow of natural gas.

Specifically, the sectional shape of the second placement groove 23 is circular, and the diameter of the inner surface of the second placement groove 23 is equal to one point twice the diameter of the outer surface of the movable rod 24.

In this embodiment, the movable rod 24 is convenient to move inside the second fixing block 21 until the movement contacts the outer surface of the rotating rod 2, so as to be engaged with the inner wall of the second placing groove 23, thereby facilitating the movement of the fixing rotating rod 2.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
