Description

Technical Field

[0001] The utility model belongs to the field of gas valves, and in particular relates to a gas distributor which is easy to adjust. Background Art

[0002] The gas distributor is the core component of the gas water heater for automatically adjusting the combustion load. Multiple cavities are arranged in the gas distributor. The gas flows through the cavities and is transported to the combustion chamber. The change of the combustion load is achieved by controlling the conduction combination of each cavity, thereby ensuring that the gas water heater can accurately control the temperature.

[0003] Nowadays, gas distributors are generally equipped with multiple valves for individual control. When an emergency situation requires that all valves be closed quickly, staff are required to close the valves one by one, which greatly reduces the efficiency of closing the valves and also creates the risk of leakage due to failure to close the valves in time.

[0005] In order to achieve the above-mentioned object, the utility model provides the following technical solution: a gas distributor that is easy to adjust, comprising a shell, the interior of the shell is hollow, a ring-shaped gas pipe is fixed near the bottom of the shell, and the interior of the gas pipe is also hollow, characterized in that at least two valves are used on the outer peripheral side of the gas pipe, and an adjustment component is provided at the center of the shell;

[0006] The regulating assembly comprises an outer cover, an regulating block is fixed at the bottom of the outer cover, an regulating groove is provided on the outer circumference of the regulating block, and racks are provided on the upper and lower end surfaces of the regulating groove, and the switch of the valve is controlled by the racks.

[0007] Optionally, the outer cover slides inside the outer shell, and a handle is installed on the upper surface of the outer cover.

[0008] Optionally, a spring is fixed between the end face of the adjustment block away from the outer cover and the inner wall of the shell, an upper rack is provided on the inner wall of the adjustment slot close to the outer cover, and an annular rack is provided on the end face of the adjustment slot away from the outer cover.

[0009] Optionally, the upper rack is not arranged in an arc shape, and teeth are provided on its surface.

[0010] Optionally, the valve includes a valve body fixed on the gas pipe, a valve stem is provided in the valve body, a valve core is installed on one side of the valve stem, and a gear is fixed on the other side, the gear is a half gear arrangement, and its teeth are divided into two parts and are symmetrically arranged.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Due to the setting of the adjustment component, the upper rack can be driven to open the specified valve by rotating the outer cover. At the same time, the annular rack can quickly close all valve bodies by rotating the outer cover, so as to achieve the purpose of quickly closing all valve switches of the distributor and avoid leakage caused by the staff's failure to close in time.

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0019] As shown in Figures 1-4, a gas distributor that is easy to adjust includes a shell 10, the shell 10 is hollow inside, a ring-shaped gas pipe 11 is fixed near the bottom of the shell 10, and the inside of the gas pipe 11 is also hollow, characterized in that at least two valves are used on the outer peripheral side of the gas pipe 11, and an adjustment component is provided at the center of the shell 10, the adjustment component includes an outer cover 12, the outer cover 12 slides in the shell 10, a handle is installed on the upper surface of the outer cover 12, an adjustment block 16 is fixed at the bottom of the outer cover 12, an adjustment groove 18 is opened on the outer peripheral side of the adjustment block 16, and racks are provided on the upper and lower end surfaces of the adjustment groove 18, and the switch of the valve is controlled by the rack, a spring 17 is fixed between the end surface of the adjustment block 16 on the side away from the outer cover 12 and the inner wall of the shell 10, an upper rack 19 is provided on the inner wall of the adjustment groove 18 on the side close to the outer cover 12, and an annular rack is provided on the end surface of the adjustment groove 18 on the side away from the outer cover 12, the upper rack 19 is not arc-shaped, and teeth are provided on its surface.

[0020] The valve includes a valve body 13 fixed on the gas pipe 11, a valve stem 14 is arranged in the valve body 13, a valve core is installed on one side of the valve stem 14, and a gear 15 is fixed on the other side. The gear 15 is a half gear setting, and its teeth are divided into two parts and are symmetrically arranged. The setting of the two symmetrical teeth can prevent mutual influence when the adjustment block 16 drives the gear 15 to rotate in the forward and reverse directions.

[0021] When in use, the gas is introduced into the gas pipe 11 and then dispersedly flows out from the valve body 13. When the valve body 13 needs to be opened, the outer cover 12 is first pulled upward to make the adjustment block 16 stretch the spring 17 to move upward, and then the outer cover 12 is rotated to make the upper rack 19 rotate to the valve body 13 that needs to be opened, and then the upper rack 19 on the adjustment block 16 drives the gear 15 to rotate. The gear 15 rotates to open the valve core through the valve stem 14, and the corresponding valve body 13 will be opened at this time. Continue the above operation to open other valve bodies 13 that need to be opened. When all valves need to be opened, only one circle of the outer cover 12 is needed. That is, it greatly facilitates the operation of the staff. If all valve bodies 13 need to be closed in time, the outer cover 12 can be directly rotated at this time. Due to the elastic force of the spring 17, the annular rack at the bottom of the adjusting groove 18 in the adjusting block 16 abuts against the gear 15, and then the adjusting block 16 can be driven to rotate by continuing to rotate the outer cover 12. The rotation of the adjusting block 16 can drive all the opened valve bodies 13 to close, so as to achieve the purpose of quickly closing all valve switches of the distributor, avoiding leakage and other problems caused by the staff's untimely closing. The outer cover 12 can also be rotated in the opposite direction to close a single valve through the upper rack 19.

[0022] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
