Description

Technical Field

[0001] The utility model belongs to the technical field of electric actuators, and more specifically, particularly relates to an electric actuator which is easy to install. Background Art

[0002] The actuator is an indispensable and important part of the automatic control system. Its function is to receive the control signal sent by the controller, change the size of the controlled medium, and thus maintain the controlled variable at the required value or within a certain range. Actuators can be divided into three categories according to their energy form: pneumatic, hydraulic, and electric. Pneumatic actuators use compressed air as energy. They are characterized by simple structure, reliable and stable operation, large output thrust, convenient maintenance, fireproof and explosion-proof, and low price. Therefore, they are widely used in chemical, papermaking, oil refining and other production processes. They can be easily used with passive instruments. Even when using electric instruments or computer control, pneumatic actuators can still be used as long as the electrical signal is converted into a standard air pressure signal of 20-100kPa through an electric-to-gas converter or an electric-to-gas valve positioner. Electric actuators have convenient energy access and rapid signal transmission, but they have complex structures and poor explosion-proof performance. Hydraulic actuators are basically not used in chemical, oil refining and other production processes. They are characterized by large output thrust.

[0003] Based on the above, the inventors found that there are the following problems:

[0004] The existing electric actuator and valve are mostly connected by fixing them by threads, and the staff need to use tools when installing and removing the valve, which is very troublesome. In addition, the valves installed with the electric actuator have different sizes, and the existing electric actuator can usually only adapt to one or two sizes of valves. Its applicability is narrow and there is a lot of room for improvement.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an electric actuator that is easy to install is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0031] The installation assembly 5 includes a connecting piece 502 and a size slot 501 , and the connecting piece 502 is movably connected to the size slot 501 by snapping.

[0032] Among them, the connecting member 502 includes a handle 503, a cap 504 is provided at the lower end of the handle 503, a rectangular groove 513 is opened in the cap 504, a connecting column 507 is fixedly provided at the top of the rectangular groove 513, a spring 512 is sleeved on the connecting column 507, and a kit 506 is clamped at the lower end of the cap 504, the connecting column 507 passes through the kit 506 and is connected with a clamping head 508, and a clamping block 505 is provided at the bottom end of the kit 506. Through the clamping design of the cap 504 and the kit 506, the spring 512 can be compressed and rebounded on the connecting column 507 at will as the cap 504 and the kit 506 move closer and further away from each other, and can also drive the kit 506 and part of the connecting column 507 in the cap 504 to extend out of the bottom end of the kit 506 and retract into the kit 506 at will in the direction of the spring 512, thereby achieving a precise clamping effect.

[0033] Among them, the size slot 501 includes a sliding hole 511 and an intermediate groove 510, and the intermediate groove 510 is located in the middle position of the sliding hole 511, and the engaging block 505 is engaged with the intermediate groove 510. Through the engagement of the engaging block 505 with the intermediate groove 510, the engaging block 505 can be moved in the intermediate groove 510, thereby driving the connecting piece 502 to move flexibly in the size slot, thereby achieving the effect of being able to connect with the connecting holes 7 on valves 2 of different sizes.

[0034] The connection hole 7 includes a connection groove 1 702 and a locking groove 701 . A connection groove 2 703 is provided on the side of the connection groove 1 702 . The locking groove 701 is locked at one side of the bottom end of the connection hole 7 and is perpendicular to the connection groove 2 703 .

[0035] Among them, the connecting groove 1 702 and the connecting groove 2 703 pass through the connecting seat 6, and the engaging groove 701 matches the engaging head 508, and the engaging groove 701 does not pass through the connecting seat 6, and the connecting groove 2 703 matches the engaging head 508. The matching of the connecting groove 2 703 and the engaging head 508 can make the connecting member 502 move easily in the connecting hole 7, and the matching of the engaging head 508 and the engaging groove 701 can make the engaging head 508 completely engaged in the engaging groove 701.

[0036] Among them, the spring 512 is located between the cap 504 and the sleeve 506, and one end of the spring 512 is connected to the top of the rectangular groove 513, and the other end of the spring 512 is connected to the bottom of the sleeve 506, and the hole width of the sliding hole 511 is smaller than the slot width of the middle slot 510. Through the design of the spring 512, when the handle 503 is pressed or released, the cap 504 can move closer to or away from the sleeve 506, so that the connecting column 507 extends or retracts toward the bottom of the sleeve 506 in the direction of the spring 512. In addition, the cooperation between the locking head 508 and the locking slot 701 can achieve a flexible and simple locking effect.

[0037] The specific usage and function of this embodiment are as follows:

[0038] When using the device, first check the integrity of the device. When the electric actuator body 1 needs to install a valve 2, observe the position of the connecting hole 7 of the valve 2, and then move the handle 503 to drive the cap 504 and the set 506 to move. The engaging block 505 in the middle groove 510 can make the engaging block 505 slide in the middle groove 510, thereby driving the connecting piece 502 to slide in the size slot 501. By sliding the connecting piece 502 in the size slot 501 at will, valves 2 of different sizes can be installed. When the connecting piece 502 is moved to the upper end position of the connecting hole 7 on the valve 2, the electric actuator body 1 is moved closer to the valve 2, so that the connecting column 507 on the connecting piece 502 enters the connecting hole 7. At this time, the handle 503 is pressed to drive the cap 504 to move closer to the set 506, and at the same time compress the The spring 512 causes the connecting column 507 to move into the connecting hole 7. After the connecting column 507 passes through the connecting groove 1 702 and the connecting groove 2 703 on the connecting hole 7, and the engaging head 508 on the connecting column 507 extends out of the lower end surface of the connecting seat 6, the handle 503 is rotated to 90 degrees to drive the engaging head 503 to rotate to the lower end position of the engaging groove 701. At this time, the handle 503 is released. Under the action of the rebound force of the spring 512, the cap 504 and the kit 506 are separated. Because the kit 506 is engaged in the middle groove 510 through the engaging block 505, the cap 504 moves in the direction away from the kit 506, thereby driving the connecting column 507 to move upward, and then driving the engaging head 508 and the engaging groove 701 to fully engage, so as to achieve the effect of quickly and tightly installing the electric actuator and the valve 2. When the valve 2 needs to be replaced, the reverse operation can be performed.
