[0036] As shown in the drawings, Figures 1 to 5 The embodiments of the present application provide a support 10, which comprises a pilot valve adapter segment 11, a drive valve support segment 13 and a main valve support segment 12 integrally formed and sequentially connected, the main valve support segment 12 is used for connecting with the outer periphery of a main valve component 20 of a multi-way valve, the pilot valve adapter segment 11 is used for connecting with a pilot valve component 30 of the multi-way valve, and the drive valve support segment 13 is used for connecting with a drive valve component 40 of the multi-way valve.

[0037] In the embodiment, the pilot valve adapter support 11", the drive valve support 13" and the main valve support 12" are integrated and the pilot valve adapter section 11, the drive valve support section 13 and the main valve support section 12 of the support are formed respectively, the adapter of the three of the main valve component 20, the drive valve component 40 and the pilot valve component 30 can be realized through the integrated support 10, the problems of interference or other similar connection difficulties or connection looseness caused by stress and the like in the connection process are avoided after the multiple parts of the support and the corresponding valve components are installed and then assembled as a whole in the prior art, which is beneficial to simplify the installation steps, reduce the installation difficulty and improve the assembly efficiency, and at the same time, the setting also avoids the situation that the adapter of the main valve support 12" connected with the main valve component 20 and the drive valve support 13" connected with the drive valve component 40 affects the adapter effect of the multiple supports on the drive valve component 40, the pilot valve component 30 and the main valve component 20, which is beneficial to further improve the convenience and reliability of the multi-way valve assembly, and at the same time, it is beneficial to improve the overall structural strength and stability of the support.

[0038] Specifically, the pilot valve adapter section 11 is welded with the pilot valve component 30, the drive valve support section 13 is welded with the drive valve component 40, and the main valve support section 12 is welded with the main valve component 20. Through the welding connection, not only the firmness of the connection is improved, but also the reliability and stability of the adapter of the support 10 to the three of the main valve component 20, the drive valve component 40 and the pilot valve component 30 are ensured, and the use of connecting pieces is reduced, which is beneficial to reduce the manufacturing cost of the multi-way valve.

[0039] As shown in FIG. 1, Figures 1 to 5 The drive valve support section 13 includes the first adapter plate section 131 and the second adapter plate section 132 connected with each other, the pilot valve adapter section 11 is connected with the first adapter plate section 131, and the main valve support section 12 is connected with one end of the second adapter plate section 132 away from the first adapter plate section 131, the first adapter plate section 131 is an arc-shaped plate section with a shape adapted to the outer periphery of the drive valve component 40, the second adapter plate section 132 is a flat plate, and the first adapter plate section 131 is tangentially arranged with the second adapter plate section 132.

[0040] In the embodiment, the first adapter plate segment 131 and the main valve support segment 12 extend to opposite sides of the second adapter plate segment 132 respectively, the section of the first adapter plate segment 131 at the connecting position with the second adapter plate segment 132 is the reference surface, and the second adapter plate segment 132 is parallel to the reference surface. By limiting the shape of the first adapter plate segment 131, the first adapter plate segment 131 can better contact the outer peripheral surface of the driving valve component 40, which is conducive to ensuring the connection area and improving the tightness and stability of the connection. Further, due to the integral arrangement of the support 10, in combination with the parallel limitation of the second adapter plate segment 132 and the reference surface, smooth transition connection between the first adapter plate segment 131 and the second adapter plate segment 132 is achieved, avoiding the need to increase the curvature of the first adapter plate segment 131 in the prior art to avoid welding looseness (welding looseness of the support 10 and the driving valve component 40 or the main valve component 20) and ensure the connection area and connection effect of the driving valve support 13" and the driving valve component 40 when the main valve support 12" and the driving valve support 13" are connected through the threaded assembly, preventing the circular arc segment (equivalent to the first adapter plate segment 131 of the present application) and the straight plate segment (equivalent to the second adapter plate segment 132 of the present application) of the driving valve support 13" from being bent and connected, improving the convenience of processing the support 10 and reducing the arc extension length of the first adapter plate segment 131, avoiding stress concentration at the bent and connected position to cause the support 10 to be easily damaged at the driving valve support segment 13 position, and improving the structural strength of the support 10.

[0041] As shown in Figures 1 to 5 The first adapter plate segment 131 includes a main adapter plate segment 1311 and an auxiliary adapter plate segment 1312 connected to each other, the auxiliary adapter plate segment 1312 is connected with the second adapter plate segment 132, in the axial direction of the driving valve component 40, the width of the auxiliary adapter plate segment 1312 is the same as the width of the second adapter plate segment 132, and the width of the main adapter plate segment 1311 is smaller than the width of the auxiliary adapter plate segment 1312 and the main adapter plate segment 1311 is arranged at the middle position of the auxiliary adapter plate segment 1312.

[0042] In the embodiment, the outer periphery of the drive valve component 40 is mainly welded with the main adapter plate segment 1311, and when the drive valve component 40 is larger, it is welded with the main adapter plate segment 1311 and the auxiliary adapter plate segment 1312. By limiting the width of the main adapter plate segment 1311, the welding area is reduced on the basis of ensuring the welding effect of the welding between the outer periphery of the drive valve component 40 and the main adapter plate segment 1311, thereby realizing the miniaturization of the drive valve support segment 13 while ensuring the reliability of the welding between the drive valve component 40 and the main adapter plate segment 1311, the auxiliary adapter plate segment 1312 can improve the welding effect of the drive valve component 40 at the adapter position of the main adapter plate segment 1311 and the auxiliary adapter plate segment 1312, which is conducive to increasing the structural strength of the first adapter plate segment 131 on the basis of ensuring the welding effect of the welding between the outer periphery of the drive valve component 40 and the main adapter plate segment 1311, avoiding the situation that the structure at this position is easily damaged due to stress, prolonging the service life of the support 10, and further, the main adapter plate segment 1311 is arranged at the middle position of the auxiliary adapter plate segment 1312, which is conducive to making the stress of the drive valve support segment 13 more uniform and consistent, and is conducive to further prolonging the service life of the support 10.

[0043] Specifically, in the axial direction of the drive valve component 40, the main adapter plate segment 1311 has oppositely arranged first and second ends, the pilot valve adapter segment 11 includes a third adapter plate segment 111 and a fourth adapter plate segment 112 arranged on the side of the main adapter plate segment 1311 away from the auxiliary adapter plate segment 1312, the third adapter plate segment 111 and the fourth adapter plate segment 112 are oppositely arranged at the first and second ends, and the third adapter plate segment 111 and the fourth adapter plate segment 112 are parallel and their projections on the axial cross section of the drive valve component 40 coincide. In this way, the third adapter plate segment 111 and the fourth adapter plate segment 112 realize the spacing of the drive valve component 40 and the pilot valve component 30 in the vertical direction, avoiding the interference between the two during installation.

[0044] Further, the main valve support segment 12 is an arc-shaped plate segment with a shape adapted to the outer periphery of the main valve component 20, and in the axial direction of the drive valve component 40, the width of the second adapter plate segment 132 is the same as the width of the main valve support segment 12.

[0045] In this way, it is conducive to ensuring the welding area and welding effect of the main valve support segment 12 and the outer periphery of the main valve component 20, and the limitation of the width is also conducive to ensuring the structural strength of the main valve support segment 12 and the second adapter plate segment 132.

[0046] In the embodiment, the drive valve support segment 13 has a through hole 1301 for the adapter pipe 50 connecting the drive valve component 40 and the main valve component 20 to pass through. In this way, by cooperating the adapter pipe 50 and the through hole 1301, the installation position of the drive valve support segment 13 can be positioned on the basis of ensuring the normal installation of the adapter pipe 50, which is conducive to simplifying the installation process, improving the installation efficiency, stability and reliability.

[0047] The through hole 1301 is located at the connection between the first adapter plate segment 131 and the second adapter plate segment 132, and is partially located in the first adapter plate segment 131 and partially located in the second adapter plate segment 132. In this way, the through hole 1301 is not only arranged on the driving valve support 13” with a large curvature, which is beneficial to improve the convenience of processing the through hole 1301 and the reliability of forming and using.

[0048] Specifically, in the first embodiment as shown in FIG. 1, the cross-sectional shape of the adapter pipe 50 is circular, and the through hole 1301 is a circular hole with a shape matching the outer periphery of the adapter pipe 50. In this way, the mounting effect of the adapter pipe 50 is improved, and the reliability and stability of the installation are ensured. Figures 1 to 3 It can be understood that the shape of the through hole 1301 can be adaptively adjusted according to actual conditions. For example, in the third embodiment as shown in FIG. 3, the cross-sectional shape of the adapter pipe 50 is still circular, and the through hole 1301 is a waist-shaped hole with a shape matching the outer periphery of the adapter pipe 50, and the extension direction of the waist-shaped hole is perpendicular to the axial direction of the driving valve component 40. In this way, while ensuring the limiting and fitting effect of the adapter pipe 50 and the through hole 1301, the accommodation area of the through hole 1301 for the adapter pipe 50 is increased, so that the adapter pipe 50 can be appropriately adjusted in the through hole 1301 or can be adapted to other limiting and fitting adapter pipes 50 with different cross-sectional shapes or sizes, which is beneficial to improve the applicability of the through hole 1301.

[0049] Figure 5 Preferably, in the second embodiment as shown in FIG. 2, the through hole 1301 is a flanged hole with a flange structure 1302 in the circumferential direction, the flange structure 1302 extends away from the driving valve component 40, and the inner wall of the flange structure 1302 is in limiting and fitting with the outer periphery of the adapter pipe 50. In this way, the limiting area of the adapter pipe 50 is increased, which is beneficial to improve the connection stability between the adapter pipe 50 and the support 10, and further beneficial to improve the stability and reliability of the multi-way valve installation.

[0050] Preferably, in the second embodiment as shown in FIG. 2, the through hole 1301 is a flanged hole with a flange structure 1302 in the circumferential direction, the flange structure 1302 extends away from the driving valve component 40, and the inner wall of the flange structure 1302 is in limiting and fitting with the outer periphery of the adapter pipe 50. In this way, the limiting area of the adapter pipe 50 is increased, which is beneficial to improve the connection stability between the adapter pipe 50 and the support 10, and further beneficial to improve the stability and reliability of the multi-way valve installation. Figure 4 Preferably, in the second embodiment as shown in FIG. 2, the through hole 1301 is a flanged hole with a flange structure 1302 in the circumferential direction, the flange structure 1302 extends away from the driving valve component 40, and the inner wall of the flange structure 1302 is in limiting and fitting with the outer periphery of the adapter pipe 50.

[0051] Preferably, in the second embodiment as shown in FIG. 2, the through hole 1301 is a flanged hole with a flange structure 1302 in the circumferential direction, the flange structure 1302 extends away from the driving valve component 40, and the inner wall of the flange structure 1302 is in limiting and fitting with the outer periphery of the adapter pipe 50. In this way, the limiting area of the adapter pipe 50 is increased, which is beneficial to improve the connection stability between the adapter pipe 50 and the support 10, and further beneficial to improve the stability and reliability of the multi-way valve installation.

[0052] ​Understandably, the shape and composition of the flange structure 1302 can be adapted to the actual situation. Various flange structures 1302 can adapt to different shapes and sizes of the adapter pipe 50 to meet different usage requirements and working conditions, and also reduce the processing difficulty of the work.

[0053] like Figure 6 As shown, another embodiment of this utility model provides a multi-way valve, which includes a main valve component 20, a pilot valve component 30, a drive valve component 40, and the aforementioned bracket 10. The pilot valve component 30 has a pilot valve bracket 31, and a pilot valve adapter section 11 is used to connect to the pilot valve bracket 31 of the multi-way valve. Specifically, in this embodiment, the pilot valve adapter section 11 is welded to the pilot valve bracket 31. In this embodiment, the bracket 10 of the multi-way valve integrates the pilot valve adapter bracket 11", the drive valve bracket 13", and the main valve bracket 12", which helps to improve the overall structural strength and stability of the bracket 10. The integrated bracket 10 can realize the connection between the main valve component 20, the drive valve component 40, and the pilot valve component 30. At the same time, it avoids the situation where the connection between the main valve bracket 12" connected to the main valve component 20 and the drive valve bracket 13" connected to the drive valve component 40 is affected when connecting them. This simplifies the installation steps, reduces the installation difficulty, and improves the assembly efficiency, thereby improving the convenience and reliability of multi-way valve assembly.
