DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] An embodiment of the present application provides an actuator and a regulating valve for a valve body, which can solve the problem in the prior art that it is difficult to replace the internal components of the actuator of the valve body while ensuring sealing, and it is difficult to eliminate internal faults of the actuator while ensuring continued use.

[0035] like Figure 1 、 Figure 2 and Figure 4 As shown, on the one hand, the present application provides an actuator for a valve body, which includes:

[0036] An actuator housing 1 has an accommodating cavity therein. The actuator housing 1 comprises a first half-shell 11 and a second half-shell 12 that are detachably connected. Corresponding annular grooves are provided on the abutting surfaces of the first half-shell 11 and the second half-shell 12.

[0037] An elastic sealing ring 2, which is arranged in the annular groove;

[0038] The actuator 3 is disposed in the accommodating cavity. A portion of the actuator 3 extends out of the second half shell 12 and is used to be connected to the valve stem 4 .

[0039] During the manufacture of this valve actuator, an internal accommodating cavity is provided within the actuator housing 1, comprising a first half-shell 11 and a second half-shell 12 that are detachably connected. Corresponding annular grooves are provided on the abutting surfaces of the first and second half-shells 11, 12, and an elastic sealing ring 2 is disposed within the annular grooves. The actuator 3 is disposed within the accommodating cavity, with the actuator 3 partially extending out of the second half-shell 12 for connection to the valve stem 4. The presence of corresponding annular grooves on the abutting surfaces of the first and second half-shells 11, 12 and the elastic sealing ring 2 disposed within the annular grooves improve the sealing properties of the disassembly interface of the actuator housing 1, enhancing the sealing effect. This addresses the prior art issue of valve actuators, which makes it difficult to replace internal components while ensuring sealing, and to troubleshoot internal faults while ensuring continued use.

[0040] In this example, the size of the elastic sealing ring 2 is slightly larger than the size of the annular groove, and the sealing effect is further improved through the deformation of the elastic sealing ring 2.

[0044] In this example, eight connecting holes are provided on the lower side of the mounting seat 5, four of which are on a circle of the first diameter and four on a circle of the second diameter. They are all arranged along the circumference of the mounting holes. Generally, the four connecting holes located in the inner circle are connected to the valve body 8, and the four connecting holes in the outer circle can also be used to connect to the valve body 8 to improve applicability.

[0049] In this case, the wrench is an Allen key.

[0050] like Figure 2 As shown, in some optional embodiments, the actuator 3 includes a turbine shaft 31 and a turbine 32. One end of the turbine shaft 31 extends out of the second half shell 12 for connecting to the valve stem 4. The turbine 32 is arranged on the outside of the part of the turbine shaft 31 located in the accommodating cavity. The turbine 32 is connected to the connecting part 72. When the connecting part 72 rotates, it drives the turbine 32 to rotate, and then drives the valve stem 4 to rotate through the turbine shaft 31.

[0052] In this example, the electric drive can directly drive the turbine shaft 31 to rotate. When it is necessary to switch to manual mode, the turbine shaft 31 can be driven to move in the axial direction to connect the turbine 32 to the connecting portion 72, or the connecting portion 72 can be driven to move and connect to the turbine 32. The electric drive can be achieved through the electrical connector 20.

The actuator 3 is disposed within the accommodating cavity, with the actuator 3 partially extending out of the second half-shell 12 for connection to the valve stem 4. The presence of corresponding annular grooves on the abutting surfaces of the first and second half-shells 11, 12 and the elastic sealing ring 2 disposed within the annular grooves improve the sealing properties of the disassembly interface of the actuator housing 1, enhancing the sealing effect. This addresses the prior art issue of valve actuators, which makes it difficult to replace internal components while ensuring sealing, and to troubleshoot internal faults while ensuring continued use.
