Description

Technical Field

[0001] This application relates to the field of valve technology, and more particularly to a pressure reducing valve assembly. Background Technology

[0002] When installing the pressure reducing valve assembly, it needs to be installed on the opening in the corresponding equipment panel.

[0003] In practice, the manufacturers of the pressure reducing valve assembly and the equipment panel are often different, which frequently leads to a mismatch between the panel's opening size and the mounting dimensions of the pressure reducing valve assembly. If the panel opening is too small, the pressure reducing valve assembly cannot be installed. Changing the panel opening size requires a significant amount of work. Summary of the Invention

[0004] This application provides a pressure reducing valve assembly to solve the problems existing in the prior art, so that the mounting parts of the pressure reducing valve can be adapted to panel openings of various sizes, increasing the stability of the pressure reducing valve after installation, eliminating the need to re-drill holes in the panel for adaptation, and reducing workload.

[0005] The pressure reducing valve assembly provided in this application includes: a valve body, the valve body including a limiting surface and a connecting portion arranged sequentially along the axial direction, the connecting portion being provided with a locking portion that is movable along the axial direction; a variable diameter ring, the variable diameter ring being located between the limiting surface and the connecting portion, the variable diameter ring including a limiting portion and a mounting portion connected to each other, the limiting portion being mounted on the connecting portion, the mounting portion including at least three variable diameter strips arranged circumferentially at intervals along the connecting portion, the outer diameter of any of the variable diameter strips gradually increasing in the direction away from the locking portion, and a retaining strip for connecting with an external mounting component being connected, the retaining strip extending in the direction close to the limiting surface, and the mounting portion being elastic.

[0006] Optionally, the connecting part includes a connecting rod, and the limiting part includes a limiting sleeve, the limiting sleeve being fixed to the connecting rod.

[0007] Optionally, the variable diameter strip is mounted on the limiting sleeve, and the end of the limiting sleeve abuts against the limiting surface.

[0008] Optionally, the inner wall of the limiting sleeve is provided with a concave strip groove along the axial direction, and the outer wall of the connecting rod is provided with a convex strip block along the axial direction, and the strip groove is engaged with the outer side of the strip block.

[0009] Optionally, the connecting part includes a threaded rod, and the locking part includes a threaded sleeve with internal threads, the threaded sleeve being threaded onto the outside of the threaded rod.

[0010] Optionally, the threaded sleeve has a groove, the opening of the groove facing the variable diameter ring, and when the threaded sleeve moves toward the variable diameter ring, the variable diameter ring is at least partially accommodated in the groove.

[0011] Optionally, the inner diameter of the groove is greater than or equal to the outer diameter of the card strip.

[0012] Optionally, the locking part has an annular elastic element disposed circumferentially on the end face facing the limiting surface.

[0013] Optionally, the circumferential width of the variable diameter strip gradually increases in the direction away from the connecting portion.

[0014] Optionally, the mounting portion is provided with an elastic element inside, which abuts against the inner wall surface of the mounting portion in the circumferential direction.

[0015] The above technical solution has the following beneficial effects:

[0016] The pressure reducing valve assembly provided in this application, when the mounting hole on the panel is smaller than the size of the mounting part, reduces the outer diameter of the mounting part by pressing at least three elastic reducing strips inward, facilitating the valve body to snap into the mounting hole. This achieves the effect of adapting the valve body to mounting holes of various sizes through the retaining strips. After the reducing ring is embedded in the mounting hole, the limiting surface serves to position the panel on one side. Then, the locking part is moved closer to the limiting surface until the end of the locking part abuts against the other side of the panel, thereby achieving the effect of stably installing the pressure reducing valve on the panel. The above installation does not require re-drilling holes in the panel, reducing workload. Attached Figure Description

[0027] The technical solution of the present invention will be further described in detail below with reference to embodiments and accompanying drawings. The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0028] Please refer to the pressure reducing valve assembly provided in this application. Figure 1 It includes: valve body 1 and reducing ring 2.

[0029] Please refer to Figures 2 to 3 The valve body 1 includes a limiting surface 10 and a connecting part 11 arranged sequentially along the axial direction of the valve body 1. The connecting part 11 is provided with a locking part 12 that is movable along the axial direction.

[0030] The variable diameter ring 2 is located between the limiting surface 10 and the connecting portion 11. Please refer to... Figures 2 to 5 The variable diameter ring 2 includes a limiting part 20 and a mounting part 21 connected to each other. The limiting part 20 is mounted on the connecting part 11, thereby mounting the variable diameter ring 2 on the valve body 1. The mounting part 21 includes at least three variable diameter strips 210 arranged circumferentially along the connecting part 11. The outer diameter of any variable diameter strip 210 gradually increases in the direction away from the locking part 12 and is connected with a retaining strip 211 for connecting with an external mounting component. The retaining strip 211 extends in the direction close to the limiting surface 10. The mounting part 21 is elastic.

[0031] The external connector can be a panel 3 with mounting holes, such as sheet metal or composite material panels. The mounting holes on the panel 3 have different inner diameters. The mounting part 21 of the reducing ring 2 is embedded therein. The mounting part 21 is elastic, so that the reducing strip 210 can reduce its outer diameter (inward shrinkage) to different degrees after being subjected to force, so that the retaining strip 211 can adapt to mounting holes of various sizes. The reducing strip 210 provides structural and radial space conditions for the retaining strip 211 to reduce its outer diameter. A certain axial distance is left between the retaining strip 211 and the limiting surface 10 to provide axial space conditions for the retaining strip 211 to reduce its outer diameter. The reducing strip 210 and the retaining strip 211 can be integrally formed metal strips, plastic strips, or other strip structures that can deform to a certain extent after being subjected to force.

[0032] When the number of reducing strips 210 is three or more, the reducing strips 210 are preferably evenly distributed around the circumference of the connecting part 11 so that the reducing strips 210 abut against the inner wall of the mounting hole evenly around the circumference.

[0033] When the mounting hole of panel 3 is smaller than the size of mounting part 21, at least three elastic reducing strips 210 are pressed inward to reduce the outer diameter of retaining strip 211, making it easier for retaining strip 211 to engage with the mounting hole. This achieves the effect of adapting valve body 1 to panels 3 with mounting holes of various sizes through retaining strip 211. After being compressed, retaining strip 211 can be stably engaged with the inner wall of the mounting hole under the elastic restoring force of reducing strip 210, ensuring the stability of mounting part 21 at the connection point with the mounting hole.

[0034] like Figure 3 As shown, after the variable diameter ring 2 is embedded in the mounting hole, the limiting surface 10 is used to position one side of the panel 3. Then, the locking part 12 moves towards the limiting surface 10 until the end of the locking part 12 abuts against the other side of the panel 3 for limiting, thereby achieving the effect of stably installing the pressure reducing valve on the panel 3.

[0035] In an optional embodiment, the connecting part 11 includes a connecting rod 110, and the limiting part 20 includes a limiting sleeve 200, which is fixedly mounted on the connecting rod 110 for stable and reliable operation. Please refer to... Figures 2 to 3 The limiting sleeve 200 can be a metal sleeve, press-fitted onto the connecting rod 110 with an interference fit, or the limiting sleeve 200 can be an elastic sleeve such as rubber, which expands outward under force when fitted onto the connecting rod 110 and is fixed onto the connecting rod 110 under elastic action. During installation, the limiting sleeve 200 is inserted into the connecting rod 110 from one end, and then other components are installed on the connecting rod 110.

[0036] In an optional embodiment, the variable diameter strip 210 is mounted on the limiting sleeve 200, and the limiting sleeve 200 abuts against the limiting surface 10. Please refer to... Figures 2 to 3 The variable diameter strip 210 can be installed on the limiting sleeve 200 by means of integral molding, welding or other methods. When the limiting sleeve 200 is installed on the connecting rod 110, the locking strip 211 is also positioned accordingly. The limiting sleeve 200 abuts against the limiting surface 10, which can further limit the variable diameter ring 2.

[0037] In an optional embodiment, the inner wall surface of the limiting sleeve 200 is provided with a concave strip groove along the axial direction, and the outer wall surface of the connecting rod 110 is provided with a convex strip block along the axial direction. The strip groove is engaged with the outer side of the strip block, which can play a circumferential limiting role for the limiting sleeve 200, prevent the limiting sleeve 200 from rotating in the circumferential direction, and increase the stability of the limiting sleeve 200 installed on the connecting rod 110.

[0038] In an optional embodiment, the connecting portion 11 includes a threaded rod 111, and the locking portion 12 includes a threaded sleeve 120 with internal threads, the threaded sleeve 120 being threaded onto the outside of the threaded rod 111. The threaded sleeve 120 is threaded onto the threaded rod 111. After the retaining strip 211 is engaged in the mounting hole of the panel 3, the threaded sleeve 120 moves axially along the connecting portion 11 to press against the other side of the panel 3, thereby achieving a secure connection between the pressure reducing valve and the panel 3.

[0039] In an optional embodiment, the threaded sleeve 120 has a groove 121, the opening of which faces the reducing ring 2. When the threaded sleeve 120 moves toward the reducing ring 2, the reducing ring 2 can be at least partially accommodated within the groove 121. The groove 121 can avoid the position of the reducing ring 2 during the movement of the threaded sleeve 120, preventing positional interference between the threaded sleeve 120 and the reducing ring 2 when the threaded sleeve 120 moves toward the panel 3.

[0040] In an optional embodiment, the inner diameter of the groove 121 is greater than or equal to the outer diameter of the retaining strip 211. When the inner diameter of the groove 121 is greater than the outer diameter of the retaining strip 211, the threaded sleeve 120 can move without any positional interference with the reducing ring 2. When the inner diameter of the groove 121 is equal to the outer diameter of the retaining strip 211, the groove 121 can simultaneously limit the retaining strip 211 through its inner wall when the retaining strip 211 is engaged in the mounting hole on the panel 3 without retraction.

[0041] In an optional embodiment, an annular elastic element is provided circumferentially on the end face of the locking part 12 facing the limiting surface 10. When the locking part 12 abuts against the panel 3, the annular elastic element can reduce damage to the locking part 12 and the panel 3 at the contact surface. The annular elastic element can also be further configured as a sealing elastic element to create a sealing effect between the locking part 12 and the panel 3.

[0042] In an optional embodiment, the circumferential width of the variable diameter strip 210 gradually increases in the direction away from the connecting portion 11 to increase the structural stability of the variable diameter strip 210.

[0043] In an optional embodiment, the mounting portion 21 is provided with an elastic element inside. The elastic element may be disc-shaped, and its outer wall abuts against the inner wall of at least three reducing strips 210 and or at least three retaining strips 211, so that after at least three retaining strips 211 are compressed under force, the elastic element will push the retaining strips 211 stably against the inner wall surface of the mounting hole of the panel 3 under elastic action.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
