Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to a stainless steel tee adapter. Background Technology

[0002] Fittings, such as tees and two-way connectors, are commonly used in pipe connections. A tee fitting consists of three openings used to connect three pipe fittings, allowing fluid to flow separately within the tee. They are widely used in pipeline networks for transporting liquids and gases. Tee fittings are classified by material (carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, PVC, etc.), branch direction (positive tee and oblique tee), and connection method (standard, threaded, compression fitting, and socket tee).

[0003] Stainless steel tee adapters are widely used as key connecting components in various piping systems. Traditional stainless steel tee adapters often require complex tools and cumbersome procedures when connecting main pipes to each other. For example, welding connections not only require specialized welding equipment and technicians, but also involve time-consuming, labor-intensive, and costly processes for subsequent maintenance, disassembly, and re-welding. While threaded connections are relatively simple, after long-term use, factors such as vibration and pressure changes can cause the threads to loosen, leading to leaks at the connection.

[0004] Therefore, it is necessary to provide a stainless steel tee adapter to solve the above-mentioned technical problems. Utility Model Content

[0025] Figure 5 This is a schematic diagram of the snap-fit ​​assembly and the clamping assembly in this utility model.

[0026] A stainless steel tee adapter includes: a main pipe 1, a secondary pipe 2, a main pipe connecting pipe 3, and a secondary pipe connecting pipe 9. A mating assembly 4 is provided inside the main pipe 1. A mating assembly 4 is also provided inside the main pipe connecting pipe 3. A locking groove 5 is formed on the main pipe connecting pipe 3. A locking assembly 6 is provided at the end of the main pipe 1, and the position of the locking assembly 6 corresponds to the locking groove 5. A first sealing groove 7 is formed on the inner side of the main pipe 1, and a first sealing ring 8 is provided inside the first sealing groove 7. A threaded groove 10 is formed on the inner side of the secondary pipe 2, and the secondary pipe connecting pipe 9 is threadedly connected to the threaded groove 10. An auxiliary sealing assembly is provided on the secondary pipe connecting pipe 9.

[0027] The main pipe 3 is aligned with the main pipe 1 and inserted. The main pipe 3 is quickly locked by the docking component 4, the locking groove 5 and the locking component 6. The first sealing groove 7 and the first sealing ring 8 enhance the sealing effect and prevent leakage. During maintenance, the locking component 6 can also be easily unlocked, which facilitates the inspection of the main pipe 1 and the main pipe 3. The auxiliary sealing component enhances the sealing effect between the secondary pipe 2 and the secondary pipe 9.

[0028] The docking assembly 4 includes a base 41, an abutment ring 43, and a docking block 45. The base 41 is fixedly connected to the inner wall of the main pipe 1 and the main pipe connecting pipe 3. The abutment ring 43 is located at the contact end of the main pipe 1 and the main pipe connecting pipe 3. The base 41 has a fluid passage port 42. The abutment ring 43 has an inclined surface 44 on the side facing the docking block 45. The docking block 45 is slidably connected to the base 41. A first spring 46 is fixedly connected to the base 41. The other end of the first spring 46 is fixedly connected to the docking block 45.

[0029] Gases, liquids, etc. enter the main pipe 1 and the main pipe connecting pipe 3 through the fluid through port 42; during installation, due to the presence of the first spring 46, the mating blocks 45 on both sides contact first, the first spring 46 is compressed, and the two sets of mating blocks 45 slide away from each other until the abutment ring 43 contacts each other.

[0030] The locking assembly 6 includes a sliding sleeve 61 and a locking ball 62. The sliding sleeve 61 is slidably connected to the end of the main pipe 1. A second spring 63 is fixedly connected to the sliding sleeve 61. The other end of the second spring 63 is fixedly connected to the main pipe 1. An clearance groove 64 is provided at the upper end of the sliding sleeve 61.

[0031] The upper part of the main pipe 1 has a passage corresponding to the size and position of the locking ball 62. When the abutment rings 43 on both sides come into contact, the locking ball 62 slides from the relief groove 64 through the passage into the locking groove 5. The second spring 63 rebounds, so that the inner side of the sliding sleeve 61 abuts the locking ball 62. At this time, the locking ball 62 and the locking groove 5 fix the main pipe 1 and the main pipe connecting pipe 3. When unlocking, the sliding sleeve 61 is pressed down until the relief groove 64 moves to the locking ball 62. The main pipe connecting pipe 3 is pulled outward. Since both sides of the locking groove 5 are inclined, the locking groove 5 pushes the locking ball 62 out into the relief groove 64, so that the main pipe connecting pipe 3 can be pulled out.

[0032] The auxiliary sealing assembly includes a fixing sleeve 11, a snap-fit ​​assembly 12, and a pressing assembly 13. The snap-fit ​​assembly 12 includes a snap-fit ​​seat 121 and a fixing seat 123. The snap-fit ​​seat 121 has an arc-shaped groove 122. The fixing seat 123 is provided with a snap-fit ​​plate 124 and an arc-shaped plate 125. The snap-fit ​​plate 124 corresponds to the snap-fit ​​seat 121, and the arc-shaped plate 125 corresponds to the arc-shaped groove 122.

[0033] When installing the fixing sleeve 11, align the fixing seats 123 on both sides of it with the locking seat 121 and rotate it until the locking plate 124 is inserted into the locking seat 121 and the arc plate 125 is inserted into the arc groove 122, thus completing the locking.

[0034] The clamping assembly 13 includes a receiving groove 131 and a threaded bolt 132. The threaded bolt 132 is provided with a handle 133, and the other end of the threaded bolt 132 is provided with an arc-shaped clamping block 134. The arc-shaped clamping block 134 is slidably connected to the receiving groove 131.

[0035] Turn the handle 133 to push the threaded bolt 132 inward, so that the arc-shaped clamping block 134 clamps the auxiliary pipe connecting pipe 9 and the second sealing ring 15, increasing stability and sealing.

[0036] The secondary pipe connecting pipe 9 is provided with a second sealing groove 14, and a second sealing ring 15 is provided in the second sealing groove 14.

[0037] The second sealing groove 14 and the second sealing ring 15 further enhance the sealing between the secondary pipe 2 and the secondary pipe connecting pipe 9.

[0038] The working principle of the stainless steel tee adapter provided by this utility model is as follows:

[0039] The main pipe 3 is aligned with the main pipe 1 and inserted. The main pipe 3 is quickly locked by the docking component 4, the locking groove 5 and the locking component 6. The first sealing groove 7 and the first sealing ring 8 enhance the sealing effect and prevent leakage. During maintenance, the locking component 6 can also be easily unlocked, which facilitates the inspection of the main pipe 1 and the main pipe 3. The auxiliary sealing component enhances the sealing effect between the secondary pipe 2 and the secondary pipe 9.
