Description

Technical Field

[0001] This utility model relates to the field of steam pipeline connection technology, and more specifically, to a dual-path synchronous quick-connect interface. Background Technology

[0002] In industrial production and many fields involving steam utilization, steam pipeline systems play a crucial role, undertaking the tasks of steam transmission and distribution to meet the steam power, heating, and other needs of different equipment. Within these steam pipeline systems, pipe connection interfaces are key components ensuring the normal operation of the system; their performance directly affects the efficiency, safety, and stability of steam transmission. However, existing technologies have the following shortcomings in their use:

[0003] Traditional interfaces have a low synchronization rate for dual intake and exhaust, which can easily lead to asynchrony between intake and exhaust, affecting the normal operating efficiency of the steam pipeline system. When installing dual intake and exhaust pipelines, steam backflow can easily occur, leading to steam leakage and the risk of burns.

[0004] Therefore, a dual-channel synchronous quick-connect interface is urgently needed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dual-path synchronous quick-connect interface, which can solve the problem that traditional interfaces have a low synchronization rate of intake and exhaust when performing dual-path intake and exhaust, which can easily lead to asynchronous intake and exhaust, affecting the normal operation efficiency of the steam pipeline system. Furthermore, when installing dual intake and exhaust pipelines, steam backflow can easily occur, leading to steam leakage and the risk of burns.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The application is as follows:

[0032] Example:

[0033] like Figure 1-10 As shown, this embodiment proposes a dual-path synchronous quick-connect interface, including a quick-connect male connector 1 and a quick-connect female connector 2. The outer wall of the quick-connect female connector 2 is provided with two symmetrically distributed guide blocks 3. A connecting ring 4 is provided on the outer wall of the quick-connect female connector 2, and an annular groove 5 is formed on one side surface of the connecting ring 4. The inner surface of the quick-connect male connector 1 has two symmetrically distributed slots 6. The operator aligns the two guide blocks 3 on the quick-connect female connector 2 with the two slots 6 on the inner surface of the quick-connect male connector 1, and then inserts one end of the quick-connect female connector 2 into the quick-connect male connector 1, so that the two guide blocks 3 are respectively inserted into the two slots 6. The inner surface of the quick-connect male connector 1 has an installation groove 7, in which a special sealing gasket 8 is installed. The side of the inner surface of the quick-connect male connector 1 near the special sealing gasket 8 is an annular arc-shaped surface. The end face of the quick-connect female connector 2 near the guide blocks 3 is θ-shaped. The special sealing gasket 8 has a tight fit on one side surface. The quick-connect male connector 1 has two main air intake channels 9 inside, and the quick-connect female connector 2 has two symmetrically distributed main return air channels 10 inside. The special sealing gasket 8 has two symmetrically distributed arc-shaped vents 11. The quick-connect female connector 2 has an integrally formed fixing ring 12 on its outer surface. The fixing ring 12 is located between the connecting ring 4 and the guide block 3. The outer surface of the fixing ring 12 abuts against the inner surface of the quick-connect male connector 1. The two arc-shaped vents 11 on the special sealing gasket 8 are connected to the two main air intake channels 9 in the quick-connect male connector 1, and are also connected to the two main return air channels 10 in the quick-connect female connector 2. This integrates the input and output interfaces, enabling dual-path synchronous switching at the frequently plugged-in and unplugged steam pipe connection. It has the advantages of high intake and exhaust synchronization rate, small size, and good sealing performance.

[0034] like Figure 1 , Figure 7 , Figure 9 and Figure 10As shown, the quick-connect female connector 2 is compatible with the quick-connect male connector 1. The guide block 3 and the connecting ring 4 are both integrally formed with the quick-connect female connector 2. The guide block 3 is compatible with the slot 6. The guide block 3 on the outer wall of the quick-connect female connector 2 is compatible with the slot 6 on the inner side of the quick-connect male connector 1, which plays the role of preventing mistake and ensuring precise docking.

[0035] like Figure 3 As shown, the special sealing gasket 8 is adapted to the mounting groove 7, and the outer surface of the special sealing gasket 8 is in contact with the inner surface of the mounting groove 7.

[0036] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the two arc-shaped vents 11 are connected to the two main air intake channels 9 respectively. The width of the main air intake channel 9 is smaller than the width of the main return air channel 10. The two arc-shaped vents 11 on the special sealing gasket 8 are connected to the two main air intake channels 9 in the quick-connect male connector 1 respectively, and are also connected to the two main return air channels 10 in the quick-connect female connector 2 respectively. Since the width of the main air intake channel 9 is smaller than the width of the main return air channel 10, this design, combined with the sealing effect of the special sealing gasket 8, can effectively prevent steam backflow.

[0037] The working principle of the above embodiment is as follows: The operator first aligns the two guide blocks 3 on the quick-connect female connector 2 with the two slots 6 opened on the inner surface of the quick-connect male connector 1. Then, one end of the quick-connect female connector 2 is inserted into the quick-connect male connector 1, so that the two guide blocks 3 are respectively inserted into the two slots 6. The end face of the quick-connect female connector 2 near the guide blocks 3 is tightly fitted with the surface of the θ-shaped special sealing gasket 8. At the same time, the outer surface of the fixing ring 12 abuts against the inner surface of the quick-connect male connector 1. The end of the quick-connect male connector 1 near the special sealing gasket 8 is located in the annular groove 5. At this time, the two arc-shaped vents 11 on the special sealing gasket 8 are respectively connected to the two main air intake channels 9 in the quick-connect male connector 1. The system is also connected to the two main return air channels 10 inside the quick-connect female connector 2. Since the width of the main air intake channel 9 is smaller than the width of the main return air channel 10, this design, combined with the sealing effect of the special sealing gasket 8, can effectively prevent steam backflow. Through the connecting ring 4, annular groove 5, and fixing ring 12 on the outer wall of the quick-connect female connector 2, a stable and sealed connection is further achieved, thus merging the input and output interfaces into one. At the steam pipe connection point where frequent plugging and unplugging occurs, dual-path synchronous on / off is achieved. It has the advantages of high intake and exhaust synchronization rate, small size, and good sealing performance, which can effectively prevent steam leakage, eliminate the risk of burns caused by steam leakage, and improve the safety of use.

[0038] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
