[0022] Embodiment 1
[0023] In the prior art, a T-shaped tee with a horizontal threaded port is usually used to add a copper elbow and a transition joint to connect with the pipeline. This method not only increases the air leakage points but also has poor overall aesthetics.
[0024] This embodiment proposes an h-shaped gas meter tee connection joint with an integrally formed structure. Refer to Figure 1 , including: a main gas pipe 1 connected to the gas meter, and branch gas pipes I 2 and II 3 connected to domestic gas appliances. The main gas pipe 1, the branch gas pipe I 2, and the branch gas pipe II 3 are of an integrally formed structure; the internal cavities of the main gas pipe 1, the branch gas pipe I 2, and the branch gas pipe II 3 are interconnected; one end of the main gas pipe 1 is connected to the gas outlet of the gas meter, and the other end is connected to the branch gas pipe I 2 and the branch gas pipe II 3; the branch gas pipe I 2 and the branch gas pipe II 3 are connected in parallel at the end of the main gas pipe 1, and the other ends are connected to domestic gas appliances. For example, the branch gas pipe I 2 and the branch gas pipe II 3 are connected to a water heater and a gas stove respectively through a gas hose 6;
[0025] Through the above solution, the tee connection joint in this embodiment is of an integrally formed structure, which ensures the overall installation style, guarantees the aesthetics, reduces the air leakage points, and facilitates subsequent safety inspections and daily maintenance.
[0026] In a specific implementation manner, the branch gas pipe I 2 is in a straight shape, and the branch gas pipe II 3 is in an L shape, so that the overall tee connection joint forms an "h" shape.
[0027] Embodiment 2
[0028] On the basis of Embodiment 1, further design is made on the sealing performance of the connection between the branch gas pipe I 2 and the branch gas pipe II 3 and the gas hose 6, including the following implementation manners:
[0029] The ends of the branch gas pipe I 2 and the branch gas pipe II 3 far from the gas meter are connected to domestic gas appliances through a gas hose 6, and an airtight structure is provided at the connection between the branch gas pipe I 2 and the branch gas pipe II 3 and the gas hose 6.
[0030] Through the design of the airtight structure, gas leakage can be prevented to ensure safe use.
[0031] In a specific implementation manner, refer to Figure 2 , the airtight structure includes a special-shaped joint 4 at the ends of the branch gas pipe I 2 and the branch gas pipe II 3, and a fastener 5 detachably connected to the special-shaped joint 4. The gas hose 6 is inserted into the special-shaped joint 4, and a sealing ring 7 is also provided between the special-shaped joint 4 and the gas hose 6.
[0032] The gas hose 6 is hermetically connected through the built-in special-shaped joint 4 of the joint, without the need for additional tools, with simple operation, simple structure, reusable, cost-saving, and the overall size of the pipeline sealing joint device is small, capable of being applicable to an environment with limited space, greatly saving the occupied space.
[0033] Furthermore, one end of the special-shaped joint 4 includes an expansion ring 401, a connecting ring 402, and a connecting seat 403. The connecting ring 402 is arranged around the expansion ring 401, and an annular cavity 404 is provided between the expansion ring 401 and the connecting ring 402; the connecting seat 403 is fixedly connected to the expansion ring 401 and the connecting ring 402 respectively, and the special-shaped joint 4 is integrally formed. The width of the annular cavity 404 matches the thickness of the gas hose 6, so that the gas hose 6 can be fixed in the annular cavity 404. The end shape of the expansion ring 401 is frustum-shaped, the outer diameter of the expansion ring 401 is larger than the inner diameter of the gas hose 6, and the inner diameter of the expansion ring 401 is the same as the inner diameter of the gas hose 6.
[0034] When the gas hose 6 is connected inward to the special-shaped joint 4, since the outer diameter of the expansion ring 401 is larger than the inner diameter of the gas hose 6 and the width of the annular cavity 404 matches the thickness of the gas hose 6, during the inward movement of the gas hose 6, due to its own deformability, the expansion ring 401 exerts a relative pressure on the gas hose 6. Under the action of the pressure, the gas hose 6 deforms, its inner diameter expands, and it is squeezed inward into the annular cavity 404, thus completing the sealing connection, without the need for additional tools, with simple operation, simple structure, reusable, cost-saving, and the overall size of the pipeline sealing joint device is small, capable of being applicable to an environment with limited space. In short, it saves space extremely.
[0035] In a further implementation manner, the length of the connecting ring 402 is less than the length of the expansion ring 401, and the sealing ring 7 is installed at the end position of the connecting ring 402. The design of the sealing ring 7 can further improve the airtight performance of the airtight structure.
[0036] In a further embodiment, the outer side of the connecting ring 402 is provided with threads, and the fastener 5 is threadedly connected to the outer side of the connecting ring 402. The fastener 5 is in the shape of a cap, and a clamping hole 501 is provided at the center of the bottom. The shape of the clamping hole 501 is composed of a frustum shape and a cylindrical shape, and the diameter of the clamping hole 501 is the same as the outer diameter of the gas hose 6.
[0037] After the gas hose 6 is connected to the special-shaped joint 4 inwardly, the fastener 5 sleeved on the outer side of the gas hose 6 is screwed inwardly to be fixedly connected to the special-shaped joint 4. A clamping hole 501 is provided in the fastener 5. The frustum part of the clamping hole 501 just fits the diameter-changing part of the gas hose 6, and the cylindrical part is in contact with the outer surface of the gas hose 6, further sealing and fixing the gas hose 6.
[0038] In a further embodiment, chamfers are provided at the corners of the outer surface of the fastener 5 to prevent bumps during operation from causing harm to the user.
