Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to an electric valve. Background Art

[0002] Electric valve is a device used to control the flow of powder materials in pipes or channels. It is usually composed of valve body, valve and motor. It can be widely used in food processing, chemical, pharmaceutical, building materials and other industries for the transportation, distribution and control of powder materials. Its main functions include precise control of powder flow, avoidance of powder leakage and contamination, and improvement of production efficiency and product quality.

[0003] At present, the existing Chinese patent with publication number CN115183042B discloses a multi-turn electric valve actuator. When the valve knife rotation needs to be automatically controlled by the actuator, the initial position of the central sleeve is close to the worm gear, and the first electromagnet is energized by the control system to attract the first electromagnet and the second electromagnet, so that the central sleeve and the worm gear are attracted to each other. At this time, the motor is started, which drives the worm to rotate, so that the worm drives the worm gear to rotate, and then drives the installation shaft to rotate. The installation sleeve rotates with the worm gear, so that the valve knife can be driven to rotate, and the valve knife in the valve is controlled to open or close, so as to control the flow between the valves. Although the device solves the above-mentioned shortcomings, the device also has the following defects: 1. The temperature inside the motor of the electric valve will increase after long-term use, resulting in an increase in the failure rate of the electric valve and affecting the service life; 2. The motor of the electric valve needs regular maintenance during long-term use to ensure the normal operation of the electric valve. The user needs to dismantle the motor for inspection, which is time-consuming and laborious. Utility Model Content

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] In the drawings, the same reference numerals all refer to the same components. Example

[0025] like Figure 1-3 As shown, the utility model provides an electric valve, including an electric valve body 22 and a motor 1, heat dissipation components 2 are arranged on both side surfaces of the motor 1, a base 3 is arranged on one side surface of the motor 1, a heat dissipation cover 4 is installed on one side surface of the base 3, a heat dissipation net 5 is arranged on one side surface of the heat dissipation cover 4, a first bolt 6 is installed on one side surface of the heat dissipation cover 4, and a first nut 7 is installed on one side surface of the first bolt 6.

[0026] Specifically, when the electric valve runs for a long time, heat accumulates inside the electric valve and air circulation is hindered, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, heat dissipation components 2 are arranged on both sides of the motor 1, and the heat dissipation components 2 are composed of a base 3, a heat dissipation cover 4, a heat dissipation net 5, a first bolt 6 and a first nut 7. A socket corresponding to the first bolt 6 is reserved on one side of the base 3, and the heat dissipation cover 4 and the heat dissipation net 5 are threadedly fixedly connected with the base 3 through the socket, the first bolt 6 and the first nut 7. Since heat dissipation components 2 are arranged on both sides of the motor 1, and heat dissipation nets 5 are installed on the heat dissipation components 2, when two sets of opposite heat dissipation nets 5 are arranged, air enters the interior of the motor 1 from the heat dissipation net 5 on one side and flows out from the heat dissipation net 5 on the other side, generating air convection from left to right and internal and external circulation, thereby taking away the heat inside the motor 1 and playing a role in dissipating the heat inside the motor 1. Example

[0027] When air circulates inside the motor 1, dust in the air and dust in the factory will be brought into the motor 1, which is not conducive to the normal operation of the motor 1. To solve this problem, the effect of the heat dissipation group is further improved, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the inner surface of the base 3 is installed with a dustproof component 8, and the dustproof component 8 is composed of a first dustproof cover 9, a first dustproof net 11, a second dustproof cover 10 and a second dustproof net 12. The lower edge of the first dustproof cover 9 and the second dustproof cover 10 after being fixedly connected by snaps is flush with the bottom of the inner side of the base 3. Semicircular mounting holes 13 are provided on the four sides of the first dustproof cover 9 and the second dustproof cover 10. A snap hole corresponding to the snap 21 provided on one side of the first dustproof cover 9 is reserved on one side of the second dustproof cover 10. After the first dustproof cover 9 and the second dustproof cover 10 are fixedly connected by snaps, the mounting hole 13 will be fitted and used to install the second bolt 14 and the second nut 15. After placing the dustproof component 8 on the inner side of the base 3 and aligning the mounting hole 13 with the socket reserved on the inner side of the base 3, the dustproof component 8 can be fixed to the inner side of the base 3 with the second bolt 14 and the second nut 15.

[0028] When in use, air enters the motor 1 from the heat dissipation component 2 on one side, and when it flows out from the heat dissipation component 2 on the other side, it will first pass through the heat dissipation net 5 and the dustproof component 8. After passing through the dustproof component 8, it will flow out from the second dustproof net 12 and the first dustproof net 11. The first dustproof net 11 and the second dustproof net 12 are grid structures and are made of polypropylene. While maintaining sufficient permeability, they can block dust and particulate matter in the air, so that they cannot enter the motor 1 through the heat dissipation component 2, so that the motor 1 has the effect of heat dissipation and ventilation while isolating the dust in the air, further improving the heat dissipation performance. Example

[0029] The motor 1 needs to be regularly inspected during long-term use to ensure the normal operation of the electric valve. The user needs to dismantle the motor 1 for inspection, which is time-consuming and laborious. Figure 1 and Figure 6 As shown, a limit plate 16 is provided on the top of the motor 1. The limit plate 16 is used to place an observation frame 17, and is provided with a socket for correspondingly installing a third bolt 19 and a third nut 20. The observation frame 17 and the observation window 18 are installed on the top of the motor 1 through the third bolt 19 and the third nut 20. The observation window 18 is made of PVC. The user can directly observe the internal operation of the motor 1 through the observation window 18, including the operating status of the rotor, the lubrication condition of the bearings, etc., and can monitor the operating status of the motor 1 in real time, including parameters such as speed and temperature, which is helpful to timely discover potential safety hazards.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
