Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, specifically to a damping control solenoid valve with controllable inlet flow. Background Technology

[0002] The working principle of an auxiliary damping control solenoid valve is as follows: Increasing the current drives the inner valve core to move closer to the inner valve sleeve. The flow cross section formed between the inner valve core step and the evenly distributed oil outlet holes of the inner valve sleeve decreases, i.e., the pilot valve flow cross section decreases. At the same time, the pressure between the cavity formed between the main valve core and the inner valve sleeve increases, and the pressure at the rear end of the main valve core increases. The main valve core moves closer to the upper cover, and the main flow cross section formed with the upper cover decreases. When the flow rate remains unchanged, the pressure will increase, and the damper will become stiffer, and vice versa. For example, an auxiliary damping control solenoid valve with publication (announcement) number: CN218817804U.

[0003] However, the maximum flow rate of existing auxiliary damping controlled solenoid valves is related to the orifice on the outermost valve seat; the size of the orifice determines the maximum flow rate of the solenoid valve. The maximum flow rate of existing auxiliary damping controlled solenoid valves is constant, meaning the inlet flow rate is not adjustable, limiting their application range.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0027] Example 1

[0028] Embodiment 1 of this utility model provides a damping control solenoid valve with controllable inlet flow, the specific structure of which is described below.

[0029] Reference Figure 1As shown, the damping control solenoid valve with controllable inlet flow mainly consists of three parts: solenoid valve body 1, upper cover 2, and component 4. The upper cover 2 is installed on the right side of the solenoid valve body 1, and component 4 is detachably connected to the upper cover 2. By replacing component 4, the inlet flow rate entering the solenoid valve can be adjusted.

[0030] Further improvements can be made to this embodiment. The valve plate seat 3 is installed on the right side of the upper cover 2, and the component 4 is installed between the upper cover 2 and the valve plate seat 3.

[0031] In some implementations of this embodiment, combined with Figure 1 As shown, in Figure 1 The damping control solenoid valve with controllable inlet flow is divided into three areas from left to right using a dashed box: the left side is the electromagnet area 8, the middle side is the pilot area 6, and the right side is the main valve area 7. The electromagnet area 8 and the pilot area 6 are existing technologies. The electromagnet area 8 outputs an electromagnetic force Fm, which is used to regulate the flow and pressure of the pilot area 6.

[0032] Furthermore, in combination Figure 1 As shown, the outer valve sleeve 5 is installed at the right end of the solenoid valve body 1. The interior of the outer valve sleeve 5 has a valve core controlled by the electromagnet region 8, which, in conjunction with... Figure 1 and Figure 2 As shown, the upper cover 2 is installed at the right port of the outer valve sleeve 5, and the center of the upper cover 2 is provided with a third oil passage 201 to facilitate the passage of oil.

[0033] In some implementations of this embodiment, combined with Figure 1 , Figure 2 and Figure 3 As shown, the valve seat 3 is in the shape of a round cap. The valve seat 3 is fitted onto the outside of the right end of the upper cover 2. It should be noted that the outer valve sleeve 5 and the valve seat 3 are connected in a detachable manner. For example, the outer valve sleeve 5 is provided with external threads and the valve seat 3 is provided with internal threads. The outer valve sleeve 5 and the valve seat 3 are fixed by threaded connection. Alternatively, the outer valve sleeve 5 and the valve seat 3 have threaded holes. The outer valve sleeve 5 and the valve seat 3 are fixed by inserting screws. Riveting, interference fit or clearance fit, etc. can also be used.

[0034] Furthermore, in combination Figure 2 and Figure 4 As shown, the surface of the valve seat 3 is provided with a first oil passage 301. The first oil passage 301 is oblong in shape and is evenly distributed around the center of the valve seat 3. A support column 303 is fixedly disposed at the center of the valve seat 3, and a support ring 302 is fixedly disposed along the edge of the valve seat 3. The first oil passage 301 is located between the support ring 302 and the support column 303.

[0035] Furthermore, combining Figure 2 , Figure 3 and Figure 4 As shown, component 4 is in the shape of a circular piece, and a second oil passage 401 is provided on the surface of component 4. The second oil passage 401 is waist-shaped and is evenly distributed around the center of component 4.

[0036] It should be noted that the first oil passage 301 and the second oil passage 401 can also be configured as a circular hole located in the center.

[0037] When component 4 is assembled inside valve seat 3, support ring 302 and support column 303 abut against the right end face of component 4, and second oil passage 401 is also located between support ring 302 and support column 303.

[0038] Because there is a cavity between the support ring 302 and the support column 303, the second oil passage 401 communicates with this cavity, and the first oil passage 301 also communicates with this cavity, thereby allowing the second oil passage 401 and the first oil passage 301 to communicate, enabling liquid to pass through both the first and second oil passages. Furthermore, combined with... Figure 2 As shown, the third oil passage 201 and the second oil passage 401 are connected to facilitate the entry of liquid into the upper cover 2 and the outer valve sleeve 5.

[0039] During use, the maximum flow rate entering the solenoid valve can be flexibly adjusted by replacing components 4 of different specifications to control the actual flow rate as needed.

[0040] Example 2

[0041] The damping control solenoid valve with controllable inlet flow in this embodiment is a further optimization based on embodiment 1.

[0042] Combination Figure 5 and Figure 6 As shown, the area (size), number, and shape of the second oil passage 401 differ in components 4 of different specifications. In this embodiment, component 4 can have three second oil passages 401. Figure 5 The second oil passage 401 is relatively small. Figure 6 The second oil passage 401 is relatively large. It can be selected according to actual needs. Figure 5 or Figure 6 Component 4 is installed into the damping control solenoid valve with controllable inlet flow.

[0043] Component 4 is simple to manufacture, low in cost, easy to assemble, and its oil passage area can be flexibly changed. Therefore, different specifications of component 4 can be used according to the actual product needs to achieve different hydraulic characteristics of solenoid valve PQ.

[0044] In summary, this utility model provides a damping control solenoid valve with controllable inlet flow, including a solenoid valve body 1, a top cover 2, and a component 4 detachably connected to the end of the top cover 2. The top cover 2 has a third oil passage 201, and the component 4 has a second oil passage 401 communicating with the third oil passage 201. It also includes a detachably connected valve seat 3, with the component 4 positioned between the valve seat 3 and the top cover 2. The valve seat 3 has a first oil passage 301 communicating with the second oil passage 401. Both the first oil passage 301 and the second oil passage 401 are configured as a central hole or circumferentially distributed holes. The solenoid valve body 1 has an outer valve sleeve 5, and the valve seat 3 is connected to the outer valve sleeve 5. The valve seat 3 and the outer valve sleeve 5 are connected by threads, screws, riveting, interference fit, or clearance fit. The inner side of the valve seat 3 has a support ring 302 and a support column 303 in contact with the surface of the component 4, with the support column 303 located at the center of the support ring 302. The number, shape, or area of ​​the second oil passages 401 in various specifications of components 4 are different. The first oil passages 301 are distributed between the support ring 302 and the support column 303, and the second oil passages 401 are also distributed between the support ring 302 and the support column 303. Multiple first oil passages 301 are evenly distributed around the support column 303. Multiple second oil passages 401 are also evenly distributed around the support column 303. Therefore, the damping control solenoid valve with controllable inlet flow of this invention has the beneficial effects of convenient inlet flow adjustment and more flexible use.
