Description

Technical Field

[0001] The utility model belongs to the technical field of gas transmission accessories, in particular to a gas pipe. Background Art

[0002] In current kitchen equipment configurations, traditional natural gas or coal gas hoses are generally designed with a single interface, which limits them to connecting a single gas supply port to a single gas stove. However, in home or commercial kitchen environments, there is often a need to temporarily expand access to multiple gas stoves for simultaneous use. To meet this need for simultaneous use, users often have to reconfigure the gas supply's intake pipe by adding additional interfaces.

[0003] However, this renovation method not only incurs high costs, including materials and labor, but also irreversibly alters the existing gas supply system. The altered intake duct permanently increases usable space, which not only takes up valuable kitchen space but also negatively impacts the overall layout and aesthetics of the kitchen. More seriously, improperly handled renovations can create safety hazards such as gas leaks, posing a threat to users' lives and property.

[0004] In addition, even if the transformation is completed and multiple gas stoves are successfully connected, when there is no need to use multiple stoves at the same time in the future, the modified air intake duct cannot be easily restored to its original state, resulting in waste of resources and idle space.

[0005] Therefore, there is an urgent need in the market for a gas pipe that can flexibly, safely and efficiently connect multiple gas stoves at the same time to overcome these defects in the prior art. Utility Model Content

The two connecting pipes 31 are coaxially docked, and one end of the two connecting pipes 31 away from the branch pipe 32 is connected to a section of the main pipe 1. The branch pipe 32 is perpendicular to the connecting pipe 31 and is connected to the docking point of the two connecting pipes 31. A valve cavity 33 is opened in the central area of ​​the branch pipe 3, that is, the valve cavity 33 is located in the common connection area of ​​the connecting pipe 31 and the branch pipe 32. A guide ring 34 is fixedly installed at the pipe openings of the two connecting pipes 31 and the branch pipe 32 toward one end of the valve cavity 33. A sealing ring 35 is embedded in the guide ring 34. The sealing ring 35 is a sealing ring commonly used for valves; a rotatable ring in the valve cavity 33 A spherical valve body 36 is installed, and the spherical valve body 36 is installed in cooperation with the guide ring 34. The spherical valve body 36 can rotate relatively under the cooperation and guidance of the guide ring 34; the spherical valve body 36 is a hollow sphere, and three channel openings 37 are opened on its side wall corresponding to the pipe openings of the connecting pipe 31 and the branch pipe 32. A valve stem 38 is fixedly connected to the spherical valve body 36, and the valve stem 38 is rotatably installed on the pipe wall of the branch pipe 3. One end of the valve stem passes through the pipe wall of the branch pipe 3 and is fixedly connected to a valve handle 39. The valve handle 39 is a regular hexagonal pyramid, and a pass / stop indicator is provided on its end face. The direction and number of the pass / stop indicator are set corresponding to the channel opening 37 on the spherical valve body 36, and the pass / stop area of ​​the branch pipe 3 can be judged by the pass / stop indicator.

[0024] Furthermore, the gas pipe further includes a nut plug 4 and an outer nut plug 54 for sealing the pipe openings of the connecting pipe 31 or the branch pipe 32 .

[0025] Specifically, a socket 321 is provided in the pipe opening at one end of the branch pipe 32 away from the connecting pipe 31, and an external threaded platform 322 is provided on the outer wall of the pipe opening at this end; the nut plug 4 includes an internal thread cover 41 and a first elastic plug 42, the internal thread cover 41 is a right hexagonal prism, an internal thread is provided on its inner wall, and the first elastic plug 42 is fixedly installed on its inner end surface, the first elastic plug 42 is a rubber plug, when the internal thread cover 41 is covered on the pipe opening of the branch pipe 32, the internal thread cover 41 and the external threaded platform 322 are threadedly matched, the first elastic plug 42 is inserted into the socket 321 and interference fits with the socket 321 to prevent gas leakage in the pipeline.

When the externally threaded column 51 is threadedly engaged in the connecting nut 21, the limiting plate is pressed against the pipe mouth of the connecting pipe 31, and the insertion column is squeezed and inserted into the connecting pipe 31.

[0027] The specific implementation process of the present invention is as follows: when a gas supply end is connected to two gas stoves, the nut plug 4 and the outer nut plug 54 are unscrewed, a connecting pipe 31 is connected to the gas supply end, a connecting pipe 31 is connected to the first gas stove, and the branch pipe 32 is connected to the existing one-to-one gas pipe, and then connected to the second gas stove through the existing one-to-one gas pipe; during use, the valve handle 39 can also be rotated by a wrench, and the spherical valve body 36 can be twisted to realize the corresponding opening of the three channel openings 37, so as to realize the switching of the two passage-like states.

[0028] When a gas supply end is connected to a gas stove, the existing one-to-one gas pipe can be replaced, or a nut plug 4 or an external nut plug 54 can be used to block the pipe opening of a connecting pipe 31 or a branch pipe 32, and the gas stove is connected to the corresponding unclosed pipe opening. At the same time, when necessary, the valve handle 39 needs to be turned to open the corresponding two channel openings 37 on the spherical valve body 36 and close the remaining channel opening 37.
