Description

Technical Field

[0001] This utility model relates to the field of split-type electric actuator technology, specifically an intelligent split-type electric actuator. Background Technology

[0002] Currently, electric valves require actuators for control. Actuators are an essential component of automatic control systems. Some valves require intelligent split-type electric actuators during use, which can separate the mechanical parts from the electrical control parts, so that leakage in the valve body will not affect the electrical control parts.

[0003] A corrosion-resistant electric actuator, disclosed in CN212986195U, includes a lower actuator housing. An upper actuator housing is movably connected to the top of the lower actuator housing, and fixed connecting plates are fixedly connected to the top of both sides of the upper actuator housing. This corrosion-resistant electric actuator features a threaded tube. The threaded tube is screwed into the upper actuator housing via a threaded tube handle and a second connecting rod handle. The threaded tube effectively connects the upper and lower actuator housings. A second locking block and a second locking block groove effectively prevent the threaded tube from slipping out of the upper actuator housing, further ensuring a tight connection between the two housings. An electric actuator sealing ring is fixedly connected inside both the upper and lower actuator housings, significantly increasing the device's corrosion resistance.

[0004] Most existing intelligent split-type electric actuators have fixed electrical control housings, which make it inconvenient to disassemble and reassemble them when the electrical control components need to be repaired, thus affecting the maintenance of the electrical control components. Therefore, we propose an intelligent split-type electric actuator that allows for quick disassembly of the electrical control housing. Utility Model Content

[0007] Furthermore, the fixing assembly includes a fixing box on the outer wall of the sealing ring that matches the opening. A lead screw is connected to the right side wall of the fixing box via a bearing. One end of the lead screw passes through the left side wall of the fixing box and is connected to an external adjustment knob. A slider is sleeved on the outer wall of the lead screw. Sliding blocks are provided on both the upper and lower side walls of the slider. Movable plates are provided on the side walls of the two sets of sliding blocks that are far apart from each other.

Under the action of the sealing ring 9, the sealing ring 3 and the sealing surface can be improved. To ensure the sealing between the grooves 8, the mounting ring 4 has positioning grooves 12 on both the upper and lower sides of its front side wall. The outer side wall of the sealing ring 3 has two sets of positioning blocks 13 that match the positioning grooves 12. With the cooperation of the positioning blocks 13 and the positioning grooves 12, the sealing ring 3 can be quickly and accurately inserted into the sealing groove 8. The mounting ring 4 has openings 11 on both the left and right sides of its front side wall. The mounting ring 4 has two sets of insertion holes 10 on both the left and right sides of its side wall. The two sets of insertion holes 10 are located on the upper and lower sides of the openings 11, respectively. The sealing ring 3 has fixing components 7 on both the left and right sides of its outer side wall that match the insertion holes 10.

[0022] Please see Figure 4 The fixing component 7 includes a fixing box 70 on the outer wall of the sealing ring 3 that matches the opening 11. A lead screw 71 is connected to the inner right side wall of the fixing box 70 via a bearing. One end of the lead screw 71 passes through the inner left side wall of the fixing box 70 and is connected to an external adjustment knob 75. A slider 76 is sleeved on the outer wall of the lead screw 71. Sliding blocks 73 are provided on the upper and lower side walls of the slider 76. Movable plates 72 are provided on the side walls of the two sets of sliding blocks 73 that are far apart. The movable plates 72 are arc-shaped and can match the outer wall of the mounting ring 4.
