Description
Technical Field
[0001] The utility model relates to the technical field of servo valve protection, in particular to a servo valve dustproof heat dissipation cover. Background Art
[0002] As an important component in industrial automation control systems, servo valves are widely used in various types of mechanical equipment, such as CNC machine tools, injection molding machines, metallurgical equipment, etc. Servo valves achieve precise control of actuators by precisely controlling the pressure and flow of fluids, which plays a vital role in improving production efficiency and product quality.
[0003] However, in the actual working environment, servo valves often face problems such as dust and impurities intrusion, which not only reduce the working performance of the servo valve, but also may cause it to fail prematurely, increase maintenance costs, and may cause more serious production accidents. In addition, since the servo valve generates a certain amount of heat during operation, if the heat cannot be dissipated in time and effectively, it will also cause the internal temperature of the servo valve to rise, further aggravate wear, and even cause failure. At present, there is a lack of a comprehensive protection device on the market that can effectively prevent dust and achieve good heat dissipation.
[0004] To this end, the present application specifically proposes a servo valve dust and heat dissipation cover to solve the above technical problems. Utility Model Content
[0005] The main purpose of the utility model is to solve the above-mentioned deficiencies and provide a servo valve dust and heat dissipation cover, which can provide dust protection for the servo valve and help it to actively dissipate heat.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] Furthermore, the accommodating component includes a base connected to the shell, an upper cover hingedly arranged on the shell and cooperating with the base, and a through hole opened at the joint between the base and the upper cover for passing a plug cable that is plugged into and cooperates with the socket. The base and the upper cover are located at positions on the shell corresponding to the socket.
[0009] Furthermore, the ventilation hood includes a first hood body fixedly arranged at one side of the shell and connected thereto, and a first dust filter screen detachably arranged at an end of the first hood body away from the shell.
[0010] Further, the first cover is made of a magnetic material. The first dust filter screen includes an annular magnet and a dust filtering mesh sheet disposed within the annular magnet. A step for lapping the annular magnet is provided at one end of the first cover away from the housing.
[0011] Further, the active exhaust hood includes a second cover fixedly provided on the other side of the housing and communicating with the housing, a second dust filter screen detachably provided at one end of the second cover away from the housing, and an exhaust fan disposed in the inner cavity of the second cover.
[0012] Further, a plurality of guiding partition strips are provided around the inner wall of the housing, and the bottoms of the guiding partition strips are beveled.
[0013] Further, a sealing ring is provided at the bottom of the mounting skirt.
[0014] The beneficial effects of the present utility model are embodied in:
[0015] By providing a housing and a containing assembly, and setting the containing assembly in a form with a flip-up upper cover, it is convenient for the socket of the servo valve to be plugged and matched with an external plug.

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0026] like Figure 1-7 As shown, the utility model provides a servo valve dust and heat dissipation cover, comprising:
[0027] The housing 1 has an opening at the bottom and an extended mounting skirt 2 is arranged at the opening, and is used to cover the outside of the servo valve 10;
[0028] An accommodating assembly 3, disposed on the housing 1 and in communication therewith, and used for accommodating a socket 4 of the servo valve 10;
[0029] The ventilation and heat dissipation assembly 5 comprises a ventilation hood 51 which is connected to one side of the shell 1 and an active exhaust hood 52 which is connected to the other side of the shell 1 .
[0030] The accommodating component 3 includes a base 31 connected to the shell 1, an upper cover 32 hingedly arranged on the shell 1 and cooperating with the base 31, and a through hole 33 opened at the joint between the base 31 and the upper cover 32 for passing the cable of the plug 6 that is plugged into and cooperates with the socket 4. The base 31 and the upper cover 32 are located at positions on the shell 1 corresponding to the socket 4.
[0031] During use, cover the housing 1 outside the servo valve 10, and install the mounting skirt 2 on the same mounting plane of the servo valve 10. At this time, the socket 4 of the servo valve 10 is located in the accommodating component 3. Flip up the upper cover 32 to expose the socket 4, insert the plug 6 into the socket 4, then flip down the upper cover 32, the upper cover 32 is engaged with the base 31, and the cable of the plug 6 is clamped in the through hole 33. Thus, the servo valve 10 connected to the plug 6 inserted into the socket 4 is completely covered in the housing 1, realizing the dust-proof protection of the servo valve 10.
[0032] The active exhaust hood 52 extracts the air in the housing 1 and discharges it from the housing 1. The external air enters the housing 1 after being filtered by the ventilation hood 51, ensuring the air pressure balance between the inner cavity of the housing 1 and the outside. The air in the housing 1 flows rapidly and continuously exchanges with the outside air, taking away the heat generated by the servo valve 10, thus playing a role in heat dissipation.
[0033] In one embodiment, the ventilation hood 51 includes a first hood body 511 fixedly arranged on one side of the housing 1 and communicating with it, and a first dust-proof filter screen 512 detachably arranged at one end of the first hood body 511 away from the housing 1.
[0034] With this design, before the air outside the housing 1 enters the housing 1 through the first hood body 511, it needs to pass through the filtration of the first dust-proof filter screen 512 to ensure that the air entering the housing 1 is dust-free.
[0035] In one embodiment, the first hood body 511 is made of a magnetic material. The first dust-proof filter screen 512 includes an annular magnet 5121 and a dust filter mesh 5122 arranged inside the annular magnet 5121. A step 7 for lapping the annular magnet 5121 is arranged at one end of the first hood body 511 away from the housing 1.
[0036] With this design, the first dust-proof filter screen 512 can be lapped and adsorbed on the step 7 through the annular magnet 5121. When it needs to be disassembled and cleaned, the annular magnet 5121 can be easily separated from the step 7 manually, and the installation is the same, which is convenient and reliable.
[0037] In one embodiment, the active exhaust hood 52 includes a second hood body 521 fixedly arranged on the other side of the housing 1 and communicating with it, a second dust-proof filter screen 522 detachably arranged at one end of the second hood body 521 away from the housing 1, and an exhaust fan 523 arranged in the inner cavity of the second hood body 521.
[0038] With this design, the exhaust fan 523 discharges the air in the housing 1 to the outside, accelerating the air circulation rate in the housing 1 to take away the heat generated by the operation of the servo valve 10; the second dust-proof filter screen 522 prevents the external air from entering the housing 1.
[0039] In one embodiment, a plurality of guiding partition strips 8 are arranged around the inner wall of the housing 1, and the bottom of the guiding partition strips 8 is beveled.
[0040] With such a design, when the housing 1 is sleeved outside the servo valve 10, it is not necessary to perfectly align the two. With the guiding effect of the guiding spacer 8, the two can be automatically aligned during the sleeving process, and the guiding spacer 8 finally abuts against the outer wall of the servo valve 10, ensuring a gap is left between the servo valve 10 and the inner cavity of the housing 1 to facilitate air circulation.
[0041] In one embodiment, a sealing ring 9 is provided at the bottom of the mounting skirt 2.
[0042] With such a design, the sealing performance after the installation of the housing 1 is further improved to prevent dust from entering.
[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
[0044] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, "a plurality" means two or more. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
