Description

Technical Field

[0001] This utility model relates to the field of pipeline valve design technology, specifically to a pressure reducing valve with integrated electromagnetic on / off function. Background Technology

[0002] Patent document with patent application number CN200420033850.3 discloses an electromagnetic pressure reducing valve that integrates a pressure reducing valve and an electromagnetic on / off valve. However, the aforementioned pressure reducing valve and electromagnetic on / off valve are arranged sequentially along the length of the valve block, resulting in an overall elongated structure of the electromagnetic pressure reducing valve. This structure is not compact and cannot be used in applications with relatively small installation spaces, thus reducing the versatility of the electromagnetic pressure reducing valve. Utility Model Content

[0003] The pressure reducing valve with integrated electromagnetic on / off function designed in this utility model can at least partially solve the above problems.

[0004] The purpose of this utility model is to provide a pressure reducing valve with integrated electromagnetic on / off function, including a valve body, a pressure reducing and regulating component, and an electromagnetic on / off component. The pressure reducing and regulating component includes a pressure regulating push rod, and the electromagnetic on / off component includes an on / off piston. The pressure regulating push rod slides in a first direction, and the on / off piston slides in a second direction. The first direction and the second direction are orthogonal to each other, and the axial projection of the on / off piston covers the pressure regulating push rod.

[0005] In some embodiments, the valve body is a cuboid, and the valve body has a medium inlet, a pressure reducing port, a medium outlet, and an on / off valve mounting port. The pressure reducing and regulating component is assembled at the pressure reducing port, and the electromagnetic on / off component is assembled at the on / off valve mounting port. Along the direction surrounding the second direction, the medium inlet, the pressure reducing port, and the medium outlet are sequentially located on three adjacent sides of the cuboid.

[0006] In some embodiments, when the electromagnetic on / off assembly is assembled at the on / off valve mounting port, an electromagnetic control cavity is formed between the electromagnetic on / off valve assembly and the on / off valve mounting port. A valve cavity is formed within the valve body. The medium inlet and the pressure reducing port are connected to the valve cavity. The electromagnetic control cavity is connected to the valve cavity via a first through hole and to the medium outlet via a second through hole. The on / off piston has a first position that cuts off the communication between the first through hole and the second through hole and a second position that connects the first through hole and the second through hole.

[0007] In some embodiments, the on / off valve mounting port is a groove, and both the first through hole and the second through hole are formed on the bottom wall of the groove.

[0008] In some implementations, the electromagnetic switching component (3) is normally closed.

[0009] In some embodiments, the pressure reducing and regulating assembly further includes a diaphragm pressure reducing assembly and a pressure regulating assembly, with the pressure regulating push rod clamped between the diaphragm pressure reducing assembly and the pressure regulating assembly. A connecting damping orifice is also formed in the valve body, which connects the medium outlet to the pressure sensing area of ​​the diaphragm pressure reducing assembly.

[0010] In some embodiments, the valve body further has a pressure regulating port, the pressure regulating component is assembled in the pressure regulating port, and the pressure regulating port is opposite to and coaxially arranged with the pressure reducing port.

[0011] In some embodiments, the valve body is made of aluminum.

[0012] This utility model discloses a pressure reducing valve with integrated electromagnetic on / off function. The sliding directions of the pressure reducing and regulating component's pressure regulating push rod and the electromagnetic on / off component's on / off piston are orthogonal to each other. The axial projection of the on / off piston covers the pressure regulating push rod. This allows the pressure reducing and regulating component and the electromagnetic on / off component to be arranged on different sides of the valve body. Compared with the prior art, which arranges the pressure reducing and regulating component and the electromagnetic on / off component on the same side of the valve body, the valve body length of the pressure reducing valve in this utility model can be effectively shortened, the pressure reducing valve structure is more compact, and it can be used in working conditions with relatively small installation space, thus improving the versatility of the electromagnetic pressure reducing valve.

[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. In the drawings, for clarity, the thickness of regions and layers is exaggerated. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0025] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0026] The following example describes a pressure reducing valve with integrated electromagnetic on / off function according to this utility model. This example is only a part of the embodiments of this utility model, but the protection scope of this utility model is not limited thereto. All other embodiments obtained by those skilled in the art without inventive effort should be covered within the protection scope of this utility model.

[0027] Please refer to the reference. Figures 1 to 9As shown in the figure, according to an embodiment of the present invention, a pressure reducing valve with integrated electromagnetic on / off function is provided, including a valve body 1, a pressure reducing and regulating assembly (not labeled in the figure), and an electromagnetic on / off assembly 3. The pressure reducing and regulating assembly includes a pressure regulating push rod 21, and the electromagnetic on / off assembly 3 includes an on / off piston 31. The pressure regulating sliding direction of the pressure regulating push rod 21 is a first direction, and the on / off sliding direction of the on / off piston 31 is a second direction. The first direction and the second direction are orthogonal to each other. The axial projection of the on / off piston covers the pressure regulating push rod. See [reference needed]. Figure 3 The directions shown are the first direction, which is the vertical direction, and the second direction, which is the horizontal direction.

[0028] In this technical solution, the sliding directions of the pressure regulating push rod 21 of the pressure reducing and regulating component and the on / off piston 31 of the electromagnetic on / off component 3 are orthogonal to each other, and the axial projection of the on / off piston covers the pressure regulating push rod. This allows the pressure reducing and regulating component and the electromagnetic on / off component 3 to be arranged on different sides of the valve body 1, with the axis of the pressure reducing and regulating component and the axis of the electromagnetic on / off component nearly on the same plane. Compared with the prior art, which arranges the pressure reducing and regulating component and the electromagnetic on / off component 3 on the same side of the valve body, the valve body length of the pressure reducing valve in this utility model can be effectively shortened, the pressure reducing valve structure is more compact, and it can be applied to working conditions with relatively small installation space, thus improving the versatility of the electromagnetic pressure reducing valve.

[0029] In some embodiments, the valve body 1 is a cuboid, and the valve body 1 has a medium inlet 11, a pressure reducing port 12, a medium outlet 13, and an on / off valve mounting port 14. The pressure reducing and regulating component is assembled at the pressure reducing port 12, and the electromagnetic on / off component 3 is assembled at the on / off valve mounting port 14. Along the direction surrounding the second direction, the medium inlet 11, the pressure reducing port 12, and the medium outlet 13 are sequentially located on three adjacent sides of the cuboid. It should be noted that in one embodiment, the aforementioned cuboid can also be a cube.

[0030] In this technical solution, the valve body 1 is designed as a cuboid with six sides, and a medium inlet 11, a pressure reducing port 12, a medium outlet 13, and an on / off valve mounting port 14 are respectively provided on each adjacent side, so that each port is reasonably arranged on each side of the cuboid, thereby further improving the structural compactness of the pressure reducing valve.

[0031] In some embodiments, when the electromagnetic on / off assembly 3 is assembled at the on / off valve mounting port 14, an electromagnetic control cavity (not labeled in the figure) is formed between the electromagnetic on / off assembly and the on / off valve mounting port 14. A valve cavity (not labeled in the figure) is formed inside the valve body 1. The medium inlet 11 and the pressure reducing port 12 communicate with the valve cavity. The electromagnetic control cavity communicates with the valve cavity via a first through hole 141 and with the medium outlet 13 via a second through hole 142. The on / off piston 31 has the function of cutting off the first through hole 141. The first position, which connects to the second through hole 142, and the second position, which connects the first through hole 141 and the second through hole 142, are such that when the aforementioned medium outlet 13 needs to flow out of the medium, the electromagnetic on / off assembly 3 controls its on / off piston 31 to be in the second position; when the aforementioned medium outlet 13 needs to stop the flow of the medium, the electromagnetic on / off assembly 3 controls its on / off piston 31 to be in the first position. Specifically, the aforementioned electromagnetic on / off assembly 3 can be a normally open or normally closed electromagnetic on / off valve in the prior art. The specific normally open or normally closed valve can be reasonably selected according to actual needs.

[0032] In this technical solution, a first through hole 141 and a second through hole 142 are further provided in the valve body 1 to realize the connection and selective control between the electromagnetic control cavity and the valve cavity or the medium outlet 13.

[0033] In one specific embodiment, when the on / off piston 31 is in the second position, the medium (such as air) enters the valve chamber through the medium inlet 11 and enters the flow area of ​​the pressure regulating push rod 21. Figure 3 The steel ball in the middle (corresponding to the valve port position) enters the electromagnetic control chamber through the first through hole 141, and then flows to the medium outlet 13 through the second through hole 142 and flows out, providing complete pressure reduction of the inflowing medium. It is understood that when the on / off piston 31 is in the first position, the first through hole 141 and the second through hole 142 are cut off, thereby cutting off the supply of medium.

[0034] In some embodiments, the on / off valve mounting port 14 is a groove, and the first through hole 141 and the second through hole 142 are both formed on the bottom wall of the groove.

[0035] In this technical solution, the on / off valve mounting port 14 is designed as a groove structure, which simplifies its manufacturing difficulty. It can be understood that the groove opening is assembled to the electromagnetic on / off assembly 3, and the central axis of the groove coincides with the central axis of the on / off piston 31. At this time, the first through hole 141 and the second through hole 142 are formed on the bottom wall of the groove, and the switching between the first position and the second position can be achieved by the linear reciprocating movement of the on / off piston 31, which further simplifies the structural design.

[0036] In some implementation methods, see details. Figure 3As shown, the pressure reducing and regulating assembly also includes a diaphragm pressure reducing assembly 22 and a pressure regulating assembly 23. The pressure regulating push rod 21 is clamped between the diaphragm pressure reducing assembly 22 and the pressure regulating assembly 23. A connecting damping hole 15 is also formed in the valve body 1. The connecting damping hole 15 connects the medium outlet 13 and the pressure sensing area of ​​the diaphragm pressure reducing assembly 22. Specifically, the aforementioned diaphragm pressure reducing assembly 22 can be a commercially available diaphragm pressure reducing valve.

[0037] In this technical solution, the existing mature diaphragm pressure reducing component 22 is used, which can ensure reliable pressure reduction while further simplifying the overall structural design of the pressure reducing valve.

[0038] In some embodiments, the valve body 1 further has a pressure regulating port 16, and the pressure regulating component 23 is assembled in the pressure regulating port 16. The pressure regulating port 16 is opposite to and coaxially arranged with the pressure reducing port 12. By placing the pressure regulating component 23 in the pressure regulating port 16, the pressure reducing pressure can be adjusted more flexibly, and the operation is convenient.

[0039] In some embodiments, the valve body 1 is made of aluminum, which reduces the overall weight of the pressure reducing valve.

[0040] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
