[0002] The electric valve actuator is the core component for realizing remote control and automatic opening and closing of valves. Its installation and coordination efficiency with the valve directly affects the commissioning cycle and maintenance cost of industrial pipeline systems. The existing patented quick-disassembly and assembly structure for internal thread valves, patent publication number CN207486107U, includes an internal thread valve body with a mounting screw hole at at least one end, which is located on the outer peripheral wall of the valve port of the internal thread valve body; and also includes a connector, which has a first connecting end that mates with the internal thread valve body and a second connecting end that connects to the pipeline. The first connecting end has a radially protruding skirt with arc-shaped elongated holes, the number of which corresponds to the mounting screw holes on the corresponding ends of the internal thread valve body; screws pass through the arc-shaped elongated holes to lock the mounting screw holes, realizing a tight connection between the connector and the internal thread valve body. This utility model utilizes the connection between the internal thread valve body and the connector to enable convenient and quick assembly of the internal thread valve onto the pipeline; the outer peripheral wall of the valve port at the end of the internal thread valve body is provided with a mounting screw hole, and the connector is provided with an arc-shaped elongated hole. The arc-shaped elongated hole facilitates the alignment and assembly of the mounting screw hole, reduces the cost of use, simplifies maintenance and replacement, and makes installation convenient and quick.

[0003] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: Existing valve electric actuators are widely used in various fluid pipeline systems for automated valve control. However, the installation of existing valve electric actuators and valves typically employs bolt connections, which are cumbersome and difficult to disassemble. Furthermore, equipment maintenance, repair, or replacement of the electric actuator requires significant time and labor costs. Therefore, we propose a quick-installation structure for valve electric actuators to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-installation structure for valve electric actuators. This solves the problem that existing valve electric actuators are widely used in various fluid pipeline systems for automated valve control. Current installation methods typically involve bolt connections, which are cumbersome and difficult to disassemble. Furthermore, maintenance, repair, or replacement of the electric actuator requires significant time and labor costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick-installation structure for a valve electric actuator, including a support mechanism, wherein a guide rail mechanism is fixedly connected to the front end of the outer periphery of the support mechanism, and a longitudinal groove with a one-way opening at the front end is provided inside the guide rail mechanism;

[0015] Beneficial effects:

[0016] The quick-installation structure of this valve electric actuator replaces the traditional bolt connection method through the cooperation of the guide rail mechanism and the positioning rod. There is no need to tighten each bolt individually. The electric actuator and valve can be installed simply by inserting the bearing component and locking it with the positioning rod. Disassembly is done by reversing the operation. This significantly shortens the installation and maintenance time and reduces labor costs.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides a technical solution: a quick-installation structure for a valve electric device, including a support mechanism 1, a guide rail mechanism 3 fixedly connected to the front end of the outer periphery of the support mechanism 1, and a longitudinal groove with a one-way opening at the front end inside the guide rail mechanism 3.

[0027] The guide rail mechanism 3 has two positioning holes 301 arranged in a straight line array inside. The positioning holes 301 are bidirectional through structures on both the left and right sides. A positioning rod 3011 is inserted into the positioning hole 301. The positioning rod 3011 has an external thread on its outer circumference and is limited by tightening a nut. A bearing component 3012 is inserted into the guide rail mechanism 3.

[0028] The guide rail mechanism 3 is fixedly connected to the front end of the outer periphery of the support mechanism 1. The guide rail mechanism 3 has a longitudinal groove with a one-way opening at the front end, and two positioning holes 301 with bidirectional through-holes on the left and right sides are opened in a straight array inside. The positioning rod 3011 with external thread is inserted into the positioning hole 301 and limited by tightening nut. The bearing component 3012 is inserted into the guide rail mechanism 3. The bearing component 3012 can be quickly positioned and disassembled in the guide rail mechanism 3 through the cooperation of the positioning rod 3011 and the positioning hole 301, which is convenient for equipment maintenance and replacement.

[0029] See Figures 1-3 The outer side of the bearing component 3012 is fixedly connected with the insertion block component 3013. There are two insertion block components 3013, which are fixedly connected to the left and right sides of the bearing component 3012 in opposite directions.

[0030] Two opposing insert assemblies 3013 are fixedly connected to the outside of the bearing assembly 3012 on the left and right sides. The insert assemblies 3013 can cooperate with the slots or grooves of the external structure (such as the valve body) to achieve pre-positioning of the bearing assembly 3012 during installation, improve installation efficiency and ensure connection stability.

[0031] See Figures 2-4 The bearing assembly 3012 and the insert assembly 3013 also have through holes that match the positioning hole 301, and the positioning rod 3011 passes through them. The top surface of the bearing assembly 3012 is fixedly connected to the heightening bracket 3014.

[0032] The bearing assembly 3012 and the insert assembly 3013 have through holes that match the positioning hole 301, allowing the positioning rod 3011 to pass through. The top surface of the bearing assembly 3012 is fixedly connected to the riser bracket 3014. The positioning rod 3011 passes through the through hole and the positioning hole 301 to further lock the relative position of the bearing assembly 3012 and the insert assembly 3013. The riser bracket 3014 can adjust the installation height of the servo motor 3015 to adapt to valves of different specifications or installation spaces.

[0033] See Figures 5-6 The main body of the height-increasing bracket 3014 is a hollow structure, and a servo motor 3015 is fixedly connected to the top surface of the height-increasing bracket 3014. An output shaft is provided on the rear side of the servo motor 3015.

[0034] The main body of the heightening bracket 3014 has a hollow structure, and the top surface is fixedly connected to the servo motor 3015. The servo motor 3015 has an output shaft on the rear side. The hollow structure reduces weight without affecting the installation and heat dissipation of the servo motor 3015. The servo motor 3015 provides power input to the drive gear 3017 through the rear output shaft.

[0035] See Figures 1-2 A drive gear 3017 is mounted on the rear output shaft of the servo motor 3015. The servo motor 3015 and the drive gear 3017 together form an electric output structure.

[0036] A drive gear 3017 is installed on the output shaft of the servo motor 3015. Together, they form an electric output structure. The drive gear 3017 can mesh with the driven gear 2011 to transmit the rotational power of the servo motor 3015 to the rotating shaft assembly 201, thereby driving the valve plate mechanism 2 to open and close, and realizing the automatic control of the valve.

[0037] See Figures 3-6 The top of the servo motor 3015 is fixedly connected to the control module 3016, and the main body of the support mechanism 1 is a pipe structure that runs through both the left and right sides. The outer side of the support mechanism 1 is fixedly connected to the flange 101.

[0038] The control module 3016 is fixedly connected to the top of the servo motor 3015. The main body of the support mechanism 1 is a pipe structure that runs through both the left and right sides. The flange 101 is fixedly connected to the outside. The control module 3016 can adjust the start, stop, speed and other parameters of the servo motor 3015. The flange 101 is bolted to the valve body or pipe through the internal annular array of connecting holes 1011 to ensure the continuity of the fluid passage.

[0039] See Figures 1-2 The flange 101 has a ring array of connecting holes 1011 inside, and the bottom end of the support mechanism 1 is fixedly connected to an inclined support arm assembly 1012. There are two support arm assemblies 1012. The top ends of the two support arm assemblies 1012 are connected to the bottom end of the guide rail mechanism 3. The valve plate mechanism 2 is installed inside the support mechanism 1 through the rotating shaft assembly 201. The top end of the rotating shaft assembly 201 is fixedly connected to a driven gear 2011 that matches the drive gear 3017.

[0040] The flange 101 has connection holes 1011 arranged in a ring inside. The bottom of the support mechanism 1 is fixedly connected to two inclined support arm assemblies 1012, the top of which are connected to the bottom of the guide rail mechanism 3. The valve plate mechanism 2 is installed inside the support mechanism 1 through the rotating shaft assembly 201. The top of the rotating shaft assembly 201 is fixedly connected to the driven gear 2011 that matches the drive gear 3017. The connection holes 1011 facilitate quick disassembly and assembly of the flange 101. The support arm assembly 1012 enhances the connection strength between the support mechanism 1 and the guide rail mechanism 3. The meshing transmission between the drive gear 3017 and the driven gear 2011 ensures the accuracy and stability of the valve opening and closing action.

[0041] During operation, the support mechanism 1 serves as the basic frame. The guide rail mechanism 3, which is fixed at the front end of its outer periphery, has a longitudinal groove with a one-way opening at the front end. The bearing component 3012 can be inserted into the guide rail mechanism 3 along the longitudinal groove. The two positioning holes 301 in the guide rail mechanism 3 are arranged in a linear array and have a two-way through structure. When the bearing component 3012 is inserted into place, the positioning rod 3011 passes through the positioning hole 301 and the through hole in the bearing component 3012 and the insertion block component 3013. The positioning is fixed and limited by tightening the nut, so as to realize the quick positioning and installation of the bearing component 3012.

[0042] The insert blocks 3013 on the left and right sides of the bearing component 3012 correspond to the slots of the external valve body to form a pre-positioning structure, ensuring the centering of the bearing component 3012 when it is inserted along the guide rail. The heightening bracket 3014 is fixed to the top of the bearing component 3012. Its hollow structure reduces weight and provides an installation platform for the servo motor 3015. The drive gear 3017 is installed on the output shaft of the servo motor 3015. The control module 3016 at the top can send a signal to control the servo motor 3015 to start.

[0043] The drive gear 3017 meshes with the driven gear 2011 at the top of the rotating shaft assembly 201. When the servo motor 3015 rotates, the drive gear 3017 drives the driven gear 2011 to rotate, which in turn drives the valve plate mechanism 2 to open and close through the rotating shaft assembly 201. The flange 101 on the outside of the support mechanism 1 is connected to the pipe bolts through the connecting holes 1011 in the annular array. The two inclined support arm assemblies 1012 at the bottom end are connected to the bottom end of the guide rail mechanism 3 to enhance the overall structural stability. When disassembling, loosen the nut of the positioning rod 3011 and pull out the positioning rod 3011, and the bearing assembly 3012 can be pulled out along the longitudinal groove of the guide rail to complete the quick disassembly.

[0044] In summary, this device enables rapid multi-pipe connection operations by utilizing flange 101.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
