Description

Technical Field

[0001] This invention relates to a high-voltage quick-connect assembly and its application method. Background Technology

[0002] Quick coupling assemblies are mainly used in the field of media transportation. Using quick couplings in pipeline design can enable rapid switching of pipelines and improve the convenience for operators.

[0003] Existing quick-connect fittings have complex structures, generate waste products during use in dynamic environments, are unsuitable for the high cleanliness requirements of the aerospace field, have limited pressure resistance, and are not suitable for pipelines with larger diameters. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of existing quick-connect assemblies, which are complex in structure, generate waste during use, are not suitable for the aerospace field with high cleanliness requirements, have limited pressure resistance, and are not suitable for large-diameter pipelines. The invention proposes a high-pressure quick-connect assembly and its application method.

[0005] The technical solution adopted in this invention is:

[0006] A high-pressure quick-connect coupling assembly, characterized by:

[0007] This includes outer connectors, convex connectors, concave connectors, and snap-fit ​​connectors;

[0008] The convex connector has a first channel inside, and the convex connector has a first stepped surface and a second stepped surface with gradually increasing diameter from left to right on the outside.

[0009] The concave connector has a second channel inside. From left to right, the second channel has a third step surface and a fourth step surface that are respectively adapted to the left end face and the first step surface of the convex connector. The concave connector is sealed on the outside of the convex connector, and the fourth step surface is in contact with the first step surface. There is a gap between the third step surface and the left end face of the convex connector. The right end face of the concave connector is in contact with the second step surface. The first channel and the second channel are connected to form a medium flow channel.

[0010] The concave connector has a fifth stepped surface on its outer wall, with the smaller diameter end located on the left side. The inner wall of the outer connector has a sixth stepped surface that matches the fifth stepped surface. One end of the outer connector is fitted and snapped onto the outside of the concave connector through the cooperation of the fifth and sixth stepped surfaces, and the other end is fitted onto the outside of the convex connector. The snap-fit ​​component is located between the outer connector and the convex connector, including at least two insertion units located on the convex connector and at the right end of the second stepped surface, and snap-fit ​​units on the outer connector that are the same number as the insertion units and correspond one-to-one. An insertion unit channel is formed between adjacent snap-fit ​​units. The area on the outer connector located at the left end of the snap-fit ​​unit has a cavity to accommodate the insertion unit. The insertion unit passes through the insertion unit channel and is inserted into the corresponding snap-fit ​​unit after rotation, thereby realizing the insertion and locking of the outer connector, the convex connector, and the concave connector.

[0011] Furthermore, the insertion unit includes a fan-shaped segment, a limiting protrusion, and a positioning plate. The fan-shaped segment is disposed on the outer wall of the convex connector, the limiting protrusion is disposed on the side of the fan-shaped segment away from the concave connector, and the positioning plate is disposed at one end of the fan-shaped segment. The distance from the far end of the positioning plate to the concave connector is greater than the distance from the far end of the limiting protrusion to the concave connector.

[0012] The snap-fit ​​unit includes a fan-shaped protrusion disposed on the inner wall of the outer sleeve connector. The insertion and shifting unit channel is formed between two adjacent fan-shaped protrusions. A limiting notch adapted to the limiting protrusion is provided at the corresponding position of the fan-shaped protrusion. The cavity for accommodating the insertion and shifting unit is provided in the area of ​​the outer sleeve connector located at the left end of the fan-shaped protrusion. After the insertion and shifting unit passes through the insertion and shifting unit channel and rotates, it inserts the limiting protrusion into the limiting notch at the corresponding position.

[0013] Furthermore, the inner wall of the concave connector and the outer wall of the convex connector are radially sealed together by a sealing element.

[0014] Furthermore, the sealing element is an O-ring;

[0015] The convex joint has an annular groove on its outer wall between the first and second stepped surfaces. The depth of the annular groove along the radial direction of the convex joint is less than the diameter of the O-ring. The O-ring is installed in the annular groove.

[0016] Furthermore, the number of the insertion and shifting units is three, and the three insertion and shifting units are evenly distributed along the circumference of the convex joint.

[0017] Furthermore, the central angle corresponding to the sector segment is 50° to 60°;

[0018] The central angle corresponding to the fan-shaped protrusion is 50° to 60°.

[0019] Furthermore, the outer wall of the outer sleeve joint is provided with multiple friction grooves.

[0020] Furthermore, the fourth step surface is provided with an angle.

[0021] The present invention also proposes an application method for the above-mentioned high-voltage quick-connect assembly, which is characterized by including the following steps:

[0022] Step 1: Assembly

[0023] 1.1 The concave joint is sealed and fitted over the convex joint. In this case, the convex joint is a fixed part and the concave joint is a movable part.

[0024] 1.2 Place the outer sleeve connector over the concave connector from left to right until the insertion unit passes through the insertion unit channel. After rotating the outer sleeve connector, insert the insertion unit into the snap-fit ​​unit to complete the assembly of the high-pressure quick connector assembly.

[0025] Step 2: Work

[0026] Install the high-pressure quick coupling assembly on the corresponding equipment, introduce high-pressure medium, and after use, remove the high-pressure quick coupling assembly. The high-pressure medium will generate an axial force through the gap between the convex and concave joints. This force will further lock the relative positions of the outer joint, convex joint and concave joint.

[0027] Step 3: Disassembly

[0028] Disassemble the high-voltage quick-connect assembly using the reverse steps of step 1.

[0029] The beneficial effects of this invention are:

[0030] 1. In this invention, the snap-fit ​​component is configured as an insertion unit and a snap-fit ​​unit. By inserting the insertion unit through the insertion unit channel and inserting it into the corresponding snap-fit ​​unit from left to right, and coordinating with the medium flow direction and the gap between the third step surface and the left end face of the convex connector, the pressure-bearing capacity of the high-pressure quick-connect assembly can be improved, so that the pressure-bearing capacity of the high-pressure quick-connect assembly can reach 36 MPa. It can be used in pipelines with larger diameters, and has a simple structure, good sealing performance, and no foreign matter generation. It can be used in high-pressure and high-cleanliness environments. That is, after strength verification, the high-pressure quick-connect assembly can meet the requirements of high-pressure medium conditions with a limited increase in mass. Moreover, its internal flow channel diameter is expanded compared with the traditional diameter. In addition, the quick-connect structure is simple, with fewer components, reducing the risk of generating foreign matter, and is suitable for use in high-cleanliness environments.

[0031] 2. In this invention, the designed snap-fit ​​structure is simple and easy to operate. By inserting the insertion unit into the snap-fit ​​unit along the medium flow direction, the locking of the high-pressure quick connector assembly is ensured. In addition, the gap between the third step surface and the left end face of the convex connector further enhances the locking effect and improves the stability of the high-pressure quick connector assembly.

[0032] 3. In this invention, the radial sealing method using O-rings ensures the sealing effect between the convex and concave joints.

[0033] 4. In this invention, there are three insertion units, which are evenly distributed along the circumference of the convex joint to ensure the uniformity of the force on the convex joint.

[0034] 5. In this invention, the central angle of the sector segment is set to 50° to 60°, and the central angle of the sector protrusion is set to 50° to 60°, which can further increase the force-bearing area of ​​the sector segment and the sector protrusion and improve the pressure-bearing capacity.

[0035] 6. In this invention, the assembly process involves the concave connector and the outer connector docking towards the convex connector. A docking bevel is designed at the docking position of the convex connector and the concave connector to facilitate quick docking. The convex connector and the outer connector are constrained and limited by snap-fit ​​parts. When disassembling the quick connector, the operator releases the constraint, thereby completing the quick separation of the high-pressure quick connector assembly. The structure is simple and the disassembly and assembly are convenient. Attached Figure Description

[0042] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0043] The terms "left" and "right" used in the text are both based on... Figure 2 Described from the perspective of [the author / organization].

[0044] This invention proposes a high-voltage quick-connect assembly, such as... Figure 1 and Figure 2 As shown, it includes an outer connector 1, a convex connector 2, a concave connector 3, a seal 4, and a snap-fit ​​component;

[0045] One end of the convex connector 2 is inserted into the interior of the concave connector 3 and is sealed by the sealing element 4. The outer connector 1 is sleeved on the outside of the convex connector 2 and the concave connector 3, and the locking between the outer connector 1, the convex connector 2 and the concave connector 3 is achieved by the snap-fit ​​element and the matching stepped structure.

[0046] The functions of each component are as follows:

[0047] The sealing element 4 is used to achieve radial sealing between the convex joint 2 and the concave joint 3. The internal flow channel of the medium is formed by the convex joint 2 and the concave joint 3. The locking of the high-pressure quick connector assembly in the working state is composed of the cooperation between the outer sleeve joint 1 and the concave joint 3 and the snap-fit ​​between the outer sleeve joint 1 and the convex joint 2.

[0048] The convex connector 2 serves as a fixed component, while the concave connector 3 and the outer connector 1 serve as movable components. They are used to assemble the convex connector 2 to obtain a high-pressure quick connector assembly.

[0049] The structure of each component is as follows:

[0050] like Figure 2 As shown, the seal 4 uses an O-ring, and the sealing method is radial sealing with an O-ring. An annular groove structure is designed on the convex joint 2, and the standard piston seal size is used for design.

[0051] like Figure 3 and Figure 4As shown, the snap-fit ​​component includes a shifting unit installed on the outer wall of the convex connector 2 and a snap-fit ​​unit installed on the inner wall of the outer connector 1. The shifting unit and the snap-fit ​​unit are fitted together to achieve the limiting of the convex connector 2 and the outer connector 1. There are three shifting units and three snap-fit ​​units. Each shifting unit includes a fan-shaped segment 8, a limiting protrusion 9 and a positioning plate 10. Each snap-fit ​​unit includes a fan-shaped protrusion 5. The fan-shaped protrusion 5 is provided with a limiting notch 6 that matches the limiting protrusion 9. The snap-fit ​​unit adopts a notch fan-shaped design to match the convex fan-shaped design of the shifting unit. The angle of the fan-shaped protrusion 5 of the snap-fit ​​unit is designed to be 50° to 60°. The three fan-shaped protrusions 5 are evenly distributed in the circumference. The limiting notch 6 designed at the center of the fan-shaped protrusion 5 corresponds to the limiting protrusion 9 of the shifting unit. The two are designed to fit together to achieve the combined limiting function.

[0052] like Figure 4 As shown, the inner surface of the convex connector 2 is the medium flow surface. The inner diameter can be designed from 32mm to 65mm according to the requirements. One end of the outer surface is designed with a sealing structure, and the other end is used to set the insertion and shifting unit of the snap-fit ​​component. The insertion and shifting unit is designed in association with the snap-fit ​​unit.

[0053] Specifically: The convex connector 2 includes an integrally formed first column 21, a first hollow column 22, and a second hollow column 23. The first column 21 has a medium passage diameter of 32mm to 65mm along its axial direction in the middle. The second hollow column 23 and the first hollow column 22 are sequentially fitted around the outside of the first column 21 from left to right along its axial direction. The first hollow column 22 and the second hollow column 23 are connected to each other. The outer diameter of the first hollow column 22 is larger than the outer diameter of the second hollow column 23, thereby forming a second stepped surface 13 at the connection between the first hollow column 22 and the second hollow column 23. A first stepped surface 12 is formed at the connection between the second hollow column 23 and the first column 21 at the end away from the first hollow column 22. The outer wall of the second hollow column 23 is provided with an annular groove 7 for installing an O-ring seal. The depth of the annular groove 7 along the radial direction of the second hollow column 23 is less than the diameter of the O-ring seal.

[0054] Three sector segments 8 are evenly arranged around the first hollow column 22 near the end of the first hollow column 22 close to the second hollow column 23. The axial length of the sector segment 8 is less than the axial length of the first hollow column 22. The limiting protrusion 9 is installed in the middle of the sector segment 8 away from the second hollow column 23. The positioning plate 10 is installed at one end of the sector segment 8 away from the second hollow column 23. The distance from the far end of the positioning plate 10 to the concave joint 3 is greater than the distance from the far end of the limiting protrusion 9 to the concave joint 3.

[0055] like Figure 5As shown, the concave connector 3 adopts a three-step structure. The innermost step ensures the flow of medium, the middle step is used to guide the convex surface (i.e., the middle step is the guide and positioning surface, and its specifications and dimensions are designed in conjunction with the convex connector 2), and the outermost step surface is the sealing surface, which cooperates with the convex connector 2 to achieve a sealing effect (i.e., the outermost step surface is located on the outer wall of the concave connector 3 and is the sealing surface. Its outer surface tail end is designed with a step structure for the limiting structure of the outer connector 1). The inner surface of the concave connector 3 is the medium flow channel 11, and the inner diameter can be designed from 32mm to 65mm according to the requirements (the inner diameter of the concave connector 3 is the same as the inner diameter of the convex connector 2).

[0056] Specifically: The concave connector 3 includes an integrally connected third hollow column 31 and fourth hollow column 32. The outer diameter of the third hollow column 31 is smaller than the outer diameter of the fourth hollow column 32, thereby forming a fifth step surface 14 (outermost step surface) at the connection between the outer walls of the third hollow column 31 and the fourth hollow column 32. The fourth hollow column 32 has a first flow cavity, a second flow cavity, and a third flow cavity that are sequentially connected. The diameter of the first flow cavity is larger than the diameter of the second flow cavity, the diameter of the second flow cavity is larger than the diameter of the third flow cavity, and the diameter of the third flow cavity is the same as the inner diameter of the third hollow column 31. A fourth step surface 15 (innermost step) is formed at the connection with the second flow cavity, and a third step surface 16 (middle step) is formed at the connection between the second flow cavity and the third flow cavity. The diameter of the first flow cavity is adapted to the outer diameter of the second hollow column 23 of the convex connector 2, and the inner diameter of the second flow cavity is adapted to the outer diameter of the first column 21. The length of the second flow cavity is greater than the length of the first column 21 placed inside the second flow cavity, so that after the first column 21 is inserted into the second flow cavity, a gap is left between the left end face of the first column 21 and the third step surface 16. The inner diameter of the third flow cavity is the same as the medium passage diameter of the first column 21.

[0057] To ensure the strength of the concave joint 3, the fifth step surface 14 and the third step surface 16 are staggered along the axial direction of the concave joint 3.

[0058] like Figure 3 As shown, the inner wall of one end of the outer sleeve joint 1 is provided with a sixth step surface 17 that is adapted to the fifth step surface 14 for axial constraint of the concave joint 3. The other end is equipped with a snap-fit ​​unit of the snap-fit ​​piece. The snap-fit ​​unit of the snap-fit ​​piece is adapted to the insertion and shifting unit of the snap-fit ​​piece. The snap-fit ​​unit of the snap-fit ​​piece is arranged in a circumferentially uniform manner.

[0059] Specifically: the outer sleeve connector 1 includes a fifth hollow column 101, a sixth hollow column 102, and a seventh hollow column 103 connected in sequence. The inner diameter of the fifth hollow column 101 is smaller than the inner diameter of the sixth hollow column 102, and the inner diameter of the fifth hollow column 101 is compatible with the outer diameter of the third hollow column 31 of the concave connector 3. The inner diameter of the sixth hollow column 102 is smaller than the inner diameter of the seventh hollow column 103, and the inner diameter of the sixth hollow column 102 is compatible with the outer diameter of the fourth hollow column 32 of the concave connector 3. The length of the sixth hollow column 102 is shorter than the length of the fourth hollow column 32. A fan-shaped protrusion 5 is arranged circumferentially along the inner wall of the seventh hollow column 103 at the end away from the sixth hollow column 102. The central angle of the fan-shaped protrusion 5 is 50° to 60°. An insertion unit channel for the fan-shaped segment 8 to pass through is formed between two adjacent fan-shaped protrusions 5. Each fan-shaped protrusion 5 is provided with a limiting notch 6 that matches the shape of the limiting protrusion 9. The distance between the fan-shaped protrusion 5 and the sixth hollow column 102 is greater than the total axial length of the fan-shaped segment 8 and the limiting protrusion 9 (that is, a cavity that can accommodate the fan-shaped segment 8 and the limiting protrusion 9 is provided on the left side of the interior of the seventh hollow column).

[0060] The outer wall of the outer sleeve joint 1 is provided with multiple friction grooves, and the fourth step surface 15 is provided with an angle.

[0061] The assembly method of the high-voltage quick-connect coupling assembly proposed in this invention is as follows:

[0062] The convex connector 2 serves as a fixed end to maintain a static spatial position. The outer connector 1 and the concave connector 3 serve as moving parts to dock with each other. The O-ring is installed in the annular groove, and the concave connector 3 is fitted onto the outside of the convex connector 2. After the fitting is completed, the O-ring is compressed, the fourth step surface 15 fits with the first step surface 12, the third step surface 16 leaves a gap with the left end face of the convex connector 2, and the right end face of the concave connector 3 fits with the second step surface 13, thus completing the assembly of the concave connector 3 and the convex connector 2.

[0063] Align the sector segment 8 with the insertion unit channel inside the outer connector 1, and slip the outer connector 1 from the concave connector 3 onto the convex connector 2. After the sector segment 8 and the sector protrusion 5 are fully inserted into the cavity on the outer connector 1, rotate the outer connector 1 clockwise (or counterclockwise). When the sector protrusion 5 on the outer connector 1 contacts the positioning plate 10 and the sector segment 8 is located at the left end of the limiting protrusion 9, aligning the sector protrusion 5 with the limiting notch 6, push the outer connector 1 to the right again, so that the limiting protrusion 9 is embedded into the limiting notch 6. The high-pressure quick connector is now fully engaged. Figure 2 The image shows the state of the high-voltage quick coupling assembly after it has been connected.

[0064] The operating status of the high-voltage quick-connect coupling assembly is as follows:

[0065] After the high-pressure quick coupling assembly is supplied with high-pressure medium, the high-pressure medium flows from the concave connector 3 to the convex connector 2. The high-pressure medium will generate an axial force through the gap between the end face of the convex connector 2 inserted into the concave connector 3 and the third step surface 16. This force will further lock the relative positions of the outer connector 1, the convex connector 2 and the concave connector 3, ensuring the reliability of the operation during the flow of high-pressure medium.

[0066] The high-pressure quick coupling assembly of the present invention, through the set gap and its own structure, enables the high-pressure quick coupling assembly to have a pressure bearing capacity of up to 36 MPa.

[0067] The disassembly method for the high-voltage quick coupling assembly is as follows:

[0068] Disassembly is performed in reverse order of the assembly process, ensuring that operators can quickly and safely complete the connection of the pipeline.
