Abstract
Description
Technical Field
[0001] This utility model relates to a solenoid valve device that is easy to connect to an oil pump, and belongs to the technical field. Background Technology
[0002] Connecting the solenoid valve to the oil pump is a core technical step in achieving electro-hydraulic control in a hydraulic system. In existing technologies, the connection between the solenoid valve and the oil pump typically uses a bracket for fixation or an integrated manifold structure. Currently, traditional brackets are typically sheet-like brackets located on one side of the solenoid valve, requiring the solenoid valve to be placed horizontally before it can be installed and connected to the oil pump.
[0003] However, existing stents and connection methods have significant drawbacks:
[0004] Firstly, traditional brackets are only single-layer sheet structures, which are easily affected by vibration and impact. After long-term operation, this can cause the solenoid valve to shift, leading to oil circuit control failure or slow action.
[0005] Secondly, traditional brackets have poor rigidity and cannot effectively buffer the high-frequency vibration of the oil pump, which accelerates the wear of the valve core inside the solenoid valve and shortens its service life.
[0006] Third, the horizontally placed iron core is not stable during operation and has poor sliding properties.
[0007] In addition, some designs do not fully consider the impact of fuel impurities or oil contamination on connecting components, leading to valve core jamming or seal failure, which further reduces system reliability.
[0008] Therefore, the aforementioned vibration and sealing issues restrict the stability and durability of the hydraulic system, and the current connection method urgently needs improvement. Utility Model Content
[0009] To solve the above problems, this utility model provides a solenoid valve device that is easy to connect to an oil pump, comprising:
[0010] The solenoid valve includes a valve body component, an iron core component, and a hook component connected in sequence. A bellows is sleeved on the outside of the iron core component, and a limit part is provided at the connection between the valve body component and the bellows.
[0011] The irregular bracket includes a horizontal frame with limiting holes and fixing holes, wherein the limiting holes are fixedly engaged with the limiting parts between the valve body component and the bellows; the edge of the horizontal frame is provided with a notch, and docking lugs for connecting oil pumps are provided on both sides of the notch.
[0012] Furthermore, the limiting part is provided with an annular welding groove, which is welded to the limiting hole.
[0013] Furthermore, the non-welded portion of the edge of the annular welding groove is provided with a spring pad.
[0014] Furthermore, sealing rings are provided at the connection between the corrugated pipe and the annular welding groove, and at the connection between the corrugated pipe and the hook component.
[0015] Furthermore, the notch is an isosceles trapezoidal open structure.
[0016] Furthermore, the docking lugs are disposed on the edges of the horizontal frame on both sides of the notch, and the docking lugs are disposed perpendicular to the horizontal frame.
[0017] Furthermore, the connection between the docking lug and the horizontal frame is provided with a smooth transition.
[0018] Furthermore, the two mating lugs have rounded corners on opposite sides.
[0019] Furthermore, the docking lug is provided with mounting holes.
[0020] Furthermore, a cylindrical protrusion is provided on the side of the mounting hole away from the horizontal frame.
[0021] The beneficial effects of this utility model are:
[0022] This invention utilizes a welded connection structure between the solenoid valve and the irregularly shaped bracket to form a solenoid valve device that can directly connect to an oil pump. During connection, the solenoid valve's iron core is kept vertical, solving the problems of instability and poor sliding when the iron core is horizontal. Simultaneously, the irregularly shaped bracket, including notches, connecting lugs, and fixing holes, allows for convenient and quick connection to the oil pump. Furthermore, the rigidity of the irregularly shaped bracket is superior to traditional single-sided plate brackets, reducing interference during vibration. In addition, the inclusion of limiting holes and spring washers ensures the solenoid valve is securely fixed to the irregularly shaped bracket in a vertical position, further reducing vibration interference, preventing solenoid valve positioning misalignment, and improving equipment lifespan.

[0029] like Figure 1 As shown, this utility model provides a solenoid valve device that is easy to connect to an oil pump, comprising:
[0030] The solenoid valve includes a valve body component 24, an iron core component 23, and a hook component 21 connected in sequence. A bellows 22 is sleeved on the outside of the iron core component 23. The bellows 22 can effectively protect the iron core component 23 from external corrosion, and the bellows 22 has a corrugated folded structure that can adapt to vibration and will not interfere with the vibration of the iron core component 23. Preferably, the bellows 22 can be made of transparent material to facilitate observation of the movement of the internal iron core component 23. The upper and lower ends of the bellows 22 should be sealed to the hook component 21 and the valve body component 24 respectively to ensure sealing.
[0031] A limiting part is provided at the connection between the valve body component 24 and the bellows 22. The limiting part is used to weld to the limiting hole 14 of the irregular bracket. The limiting part can be a shaft platform with a diameter slightly larger than that of the bellows 22. Preferably, the limiting part can be provided with an annular welding groove in the middle of the shaft platform. The shaft platform is welded to the limiting hole through the annular welding groove. Spring pads can be provided at the non-welded parts of the edge of the annular welding groove to achieve buffering and vibration reduction effects. The spring pads can be provided on the upper and lower surfaces of the non-welded parts of the shaft platform.
[0032] The irregularly shaped bracket includes a horizontal frame 11 with limiting holes 14 and fixing holes 15. The horizontal frame 11 is a horizontally arranged metal plate frame, such as... Figure 2 As shown, the edge of the horizontal frame 11 has an arc-shaped rounded corner and a beveled edge. A limiting hole 14 is provided on the inner side of the arc-shaped rounded corner, and a fixing hole 15 is provided on the inner side between the arc-shaped rounded corner and the beveled edge. The limiting hole 14 is welded to the limiting part between the valve body component 24 and the bellows 22. After welding, the entire solenoid valve can be in a vertical state, perpendicular to the horizontal frame 11, thereby reducing the interference of vibration on the iron core component 23. The fixing hole 15 can be used to further fix the irregular bracket with a rod.
[0033] The horizontal frame 11 has a notch 13 on its edge, and docking lugs 12 for connecting the oil pump are provided on both sides of the notch 13. Preferably, the notch 13 is an isosceles trapezoidal open structure, which can be connected to the speed regulator component on the oil pump together with the docking lugs 12, so as to realize the direct connection between the solenoid valve and the oil pump in the vertical state.
[0034] Preferably, the docking lug 12 is disposed on the edge of the horizontal frame on both sides of the notch, the docking lug 12 is disposed perpendicular to the horizontal frame, and the connection between the docking lug 12 and the horizontal frame 11 is provided with a smooth transition to improve the stability of the connection and prevent breakage; the two docking lugs 12 are provided with rounded corners on opposite sides to effectively reduce wear between them and the speed controller components; the docking lug 12 is also provided with mounting holes, and the side of the mounting hole 16 away from the horizontal frame is provided with a cylindrical protrusion to facilitate guidance and accurate fixing during installation.
[0035] Furthermore, sealing rings are provided at the connection between the corrugated pipe 22 and the upper surface of the annular welding groove, and at the connection between the corrugated pipe 22 and the hook component 21. The sealing ring at the connection between the corrugated pipe 22 and the upper surface of the annular welding groove can be located inside the spring pad, which improves the sealing performance without interfering with the installation of the spring pad.
[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention.
