[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Example 1
[0028] Reference Figure 1 , shows a schematic structural diagram of a gas regulating tube of the present invention, which may specifically include: a tube body 1, a regulating mechanism 2 and an upper cover 3; the tube body 1 and the upper cover 3 are detachably connected, and the detachable connection facilitates replacement of components when they are damaged in the future, without having to replace all parts, thereby greatly saving costs.
[0029] The tube body 1 is provided with an air inlet end at one end and an air outlet end at the other end. It should be noted that the air inlet end and the air outlet end are respectively provided with connecting structures so that the gas regulating tube is sealed and connected with other components to prevent leakage during gas transportation and cause danger. It is more preferred that threads are respectively provided at both ends and connected in the gas transmission pipeline, including but not limited to the method of providing threads, and can also be connected by snap-fit.
[0030] Further, combined with Figure 2 and Figure 3 A first gas outlet 4 is also provided at the side end of the tube body 1. It should be noted that the gas regulating tube is a section of a pipeline located in the gas transmission system. It is not only delivered to a certain device, but also needs to be delivered to the next-level system. The first gas outlet 4 is delivered to a specific device. At the same time, the first gas outlet 4 also needs to be provided with a seal. In actual use, it is connected to the gas transmission pipeline and a seal is provided to prevent gas leakage and cause poisoning of personnel. The regulating mechanism 2 is arranged in the cavity formed by the tube body 1 and the upper cover 3, and its control part extends out of the cavity, and is also arranged between the gas outlet end and the first gas outlet 4, for regulating the flow of gas entering the first gas outlet 4. It should be supplemented that the upper cover 3 is connected to the tube body 1. A mounting hole for the regulating mechanism 2 is provided. The mounting hole is located at the side end of the gas regulating tube as a whole and is opened to the gas regulating tube, forming an upper half of the mounting hole on the tube body 1 and the upper cover 3 has the other half of the mounting hole. The two together constitute a completed mounting hole, and the regulating mechanism 2 is arranged in the mounting hole. A sealing member needs to be provided in the mounting hole to prevent gas leakage.
[0031] Example 2
[0032] Reference Figure 1 , Figure 2 and Figure 3 For explanation, the gas regulating tube also includes a second gas outlet 5, which is arranged at the side end of the tube body 1 and is not in the same vertical plane as the first gas outlet 4. A seal is also required to prevent gas leakage during actual use. It is more preferred that the first gas outlet 4 and the second gas outlet 5 are symmetrically arranged with respect to the center of the tube body 1. Furthermore, the mounting hole is located at the connection between the upper cover 2 and the tube body 1, at the side end of the gas regulating tube, and also between the first gas outlet 4 and the second gas outlet 5. The gas outlet volume of the first gas outlet 4 and the second gas outlet 5 is controlled by controlling the regulating mechanism 2.
[0033] In the following description, it is assumed that the first air outlet 4 is close to the air inlet end, and the second air outlet 5 is close to the air outlet end. Of course, the setting can also be reversed. This is only used for explanation.
[0034] Further, combined with Figure 4 The gas regulating pipe also includes a flow guiding structure, which realizes the concentrated flow of gas in a preset direction to prevent the gas from not moving in the preset direction. The flow guiding structures are respectively arranged at the position where the first gas outlet 4 and the second gas outlet 5 are arranged on the inner wall of the tube body 1. The gas is transported from the gas inlet end of the tube body 1. Under the flow guiding effect of the first gas outlet 4, more gas flows to the first gas outlet 4. Similarly, the flow guiding structure of the second gas outlet 5 also transports a large amount of gas in the direction of the second gas outlet 5. The flow of the first gas outlet 4 and the second gas outlet 5 can be adjusted by controlling the regulating mechanism 2 arranged between the first gas outlet 4 and the second gas outlet 5.
[0035] Furthermore, the guide structure is respectively arranged at the position where the first air outlet 4 and the second air outlet 5 are arranged on the inner wall of the tube body. It is more preferred that the guide structure is arranged as a column with openings at only two ends, wherein one end of the opening is connected to the air outlet, and the other opening direction is arranged to be away from the regulating mechanism 2. The first air outlet 4 and the second air outlet 5 are respectively arranged with the guide structure, and the diverging directions can transport the gas entering the guide structure only to the air outlet position where it is located, while the gas that has not entered the guide structure continues to flow in the gas regulating pipe.
[0036] Example 3
[0037] Recombination Figure 5 and Figure 6For explanation, the regulating mechanism 2 is a first regulating mechanism 21 and a second regulating mechanism 22. It should be noted that the first regulating mechanism 21 is arranged near the first gas outlet 4, and the second regulating mechanism 22 is arranged near the second gas outlet 5. The two regulating mechanisms 2 are arranged to more accurately control the amount of gas output from the first gas outlet 4 and the second gas outlet 5. Furthermore, the first regulating mechanism 21 includes a shaft-linked air blade 214, a dial 213, a handle 212 and a nut cap 211. The shaft of the shaft-linked air blade 214 passes through the dial 213, the handle 212 and the nut cap 211 in sequence, and the handle 212 abuts against the dial 213 and the nut cap 211 respectively. It should be noted that the shaft-linked wind blade 214 is a shaft with a linked wind blade welded thereto, and a thread is set at one end of the shaft-linked wind blade 214 away from the linked wind blade, and the shaft of the shaft-linked wind blade 214 is processed by a lathe at the end with the thread, so that the shaft-linked wind blade 214 and the handle 212 can rotate synchronously. When the handle 212 is rotated, the shaft-linked wind blade 214 can be rotated. It is more preferred to set a group of gear meshing transmission, and a gear end face center is set, which is connected to the threaded end of the shaft-linked wind blade 214. A hole of the same shape as the end face of the belt-shaft linkage wind blade 214 is provided, and a gear groove meshing with the gear is provided at the end of the handle close to the dial 213. The gear is provided between the dial 213 and the handle 212. A hole slightly larger than the diameter of the belt-shaft linkage wind blade 214 is provided at the center of the handle 212, so that the handle 212 can be rotated, and the belt-shaft linkage wind blade 214 can also be rotated by a corresponding angle through gear transmission; a hole of the same shape as the end face of the belt-shaft linkage wind blade 214 with a threaded end can also be provided at the end face of the handle 212. Further, the nut cap 211 is screwed onto the belt-shaft linkage wind blade 214, so that the dial 213 and the handle 212 are fixed by the nut cap 211. In summary, it is convenient to rotate the handle 213 and the belt-shaft linkage wind blade 214 at the same time.
[0038] Further, combined with Figure 7The dial 213 records the change in the flow rate of the gas entering the first air outlet 4 and the second air outlet 5 as a numerical value every time the shaft-linked wind blade 214 rotates a certain angle, and corresponds one to one with the scales on the dial 213. Furthermore, the scales on the dial 213 are high fire, medium fire and low fire, and the gas output of the first air outlet 4 and the second air outlet 5 can be achieved by rotating the angle to achieve high fire, medium fire and low fire. The scale plate 213 needs to be fixed and cannot rotate with the rotation of the shaft-linked wind blade 214. It is more preferred to set an external connection structure for the scale plate 213 after installation, which can be a screw connection. It is more preferred to set a snap-on structure to clamp the scale plate 213 on the upper cover 3. It is only necessary to fix the scale plate so that it cannot rotate with the rotation of the handle 212, thereby driving the rotation of the shaft-linked wind blade 214 and then making the scale plate rotate. It is more preferred that a circular hole with a diameter larger than the outer diameter of the gear is set in the center of the scale plate, and the handle 212 is also provided with a pointer. Before starting work, the pointer can be pointed to a certain position of the scale plate to set its position to the initial state.
[0039] Furthermore, combined Figure 8 The second regulating mechanism 22 is a total regulating valve welded by a shaft-linked air vane and a paddle. The first regulating mechanism 21 is arranged near the first gas outlet 4, and the second regulating mechanism 22 is arranged near the second gas outlet 5. The second regulating mechanism 22 is only arranged in two states. The second regulating mechanism 22 is rotated to keep it in state one, which is an open state. At this time, the first gas outlet 4 and the second gas outlet 5 both discharge gas. The second regulating mechanism 22 is rotated to keep it in state one, which is a closed state. At this time, the second gas outlet 5 blocks the flow of the gas toward the second gas outlet 5 and the gas outlet end due to the second regulating mechanism 22. At this time, part of the gas goes out directly from the first gas outlet 4, and the other part is blocked by the second regulating mechanism 22, so that this part of the gas flows back, and the refluxed gas merges with the gas at the gas inlet end to form a gas flowing from the gas inlet end to the gas outlet end, and part of this part of the gas directly enters the first gas outlet 4, and so on. However, since the gas flow rate remains unchanged, the gas flowing into the first gas outlet 4 at this time cannot achieve the change of the fire, and there is a small amount of gas in the second gas outlet 5 at this time. The gas is small and cannot be continuously provided, and cannot be ignited, or even if it is ignited, it will go out once the gas is consumed, and the fire is unstable.
[0040] In summary, the functions of the first regulating mechanism 21 and the second regulating mechanism 22 can realize precise control of the gas output. First, with the scales of "off, low fire, high fire" on the dial 213 as an example, the first regulating mechanism 21 and the second regulating mechanism 22 are initially in a closed state. At this time, only the first gas outlet 4 has a continuously supplied gas. When the second regulating mechanism 22 is turned on, there is still no continuous gas flow at the second gas outlet 5. Then, the first regulating valve 4 is turned to a low fire. At this time, gas begins to flow continuously into the second regulating mechanism 22. Then, the first regulating valve 4 is turned to a high fire. At this time, a large amount of gas flows continuously into the second gas outlet 5, and then a high fire is achieved through the stove.
[0041] Further, combined with Fig. 9 The detachable connection is a threaded connection, and in order to set the thread groove and facilitate the installation of the thread, the wall thickness of the gas regulating tube at the connection is set thicker, and the wall thickness at the non-connection does not change, forming a hole with a figure of two sides of a circle cut off in a side view. Through the wall thickness setting, while being able to achieve detachability, the regulating mechanism 2 can better control the flow of gas entering the first gas outlet 4 and the second gas outlet 5.
