Abstract
Description
Technical Field
[0001] This utility model relates to a support device, and more particularly to a support device for vertically installing an electric valve actuator, belonging to the field of design and manufacturing technology of beverage production process equipment. Background Technology
[0002] In the energy production and supply chain of baijiu (Chinese liquor) production, electric valves are required for the transportation of fluids such as high-temperature, high-pressure steam and water. The electric actuators are specialized devices that drive the terminal control units, namely the valves and baffles. During use, electric actuators frequently jam, preventing the electric valves from opening and closing. Furthermore, when the motor of the electric actuator fails, it can lead to internal leakage of high-temperature, high-pressure steam. If this steam backflows into the boiler, it can easily create a production safety hazard.
[0003] When used on vertical pipelines, the electric actuator of an electric valve is perpendicular to the pipeline, according to the requirements of the production process. During production, the electric actuator is in continuous operation and requires frequent switching and adjustment. However, the electrical components of the electric actuator are subjected to uneven stress due to frequent use and gravity, which can lead to motor damage and valve jamming.
[0004] If the electric actuator of an electric valve on a vertical pipeline is not supported by a bracket, it is easy for the valve to jam due to gravity or other factors during production. This can lead to the valve being unable to open, damage to the motor, steam backflow damaging the boiler, or accidents. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a support device for vertically installed electric valve actuators that can effectively prevent electric valves from jamming due to external forces acting on the electric actuator during operation.
[0006] The technical solution adopted to solve the above-mentioned technical problems is: a support device for vertically installing electric valve actuators, comprising multiple electric valves arranged sequentially along the length direction, with the electric actuators of each electric valve suspended on the outside of the corresponding vertical steam pipe. The support device includes a base frame assembly and a support connection assembly, with the support connection assembly movably arranged on the base frame assembly, and the electric actuators of each sequentially arranged electric valve being supported on the support connection assembly.
[0007] Furthermore, the base frame assembly includes a gantry frame and fixing screws. The support connection assembly is arranged on the gantry frame in accordance with the position of the electric actuator that needs to be supported. The gantry frame is detachably fixed to the foundation at the corresponding position by means of the fixing screws along its two vertical sides.
[0008] The preferred embodiment of the above scheme is that the gantry frame is an extra-long gantry frame with a horizontal side adapted to the arrangement length of each set of electric actuators, or a number of small gantry frames that are equivalent to the number of electric actuators that need to be supported. The support connection components are detachably fixed to the foundation at the corresponding position through the extra-long gantry frame or each small gantry frame with the help of fixing screws.
[0009] Furthermore, the support connection assembly includes multiple support connection groups, the number of which is equivalent to the number of electric actuators that need to be supported. Each set of electric actuators is arranged movably on the base frame assembly through each support connection group.
[0010] The preferred embodiment of the above scheme is that each set of support connectors includes a limiting installation component, a buffer support component, and a quick-release connector. The quick-release connector is fixed on the top of the buffer support component, and the buffer support component is movably arranged on the base frame assembly at the corresponding position through the limiting installation component.
[0011] Furthermore, the limiting installation component consists of a cylindrical body with its opening facing upwards, positioned at the corresponding location on the base frame assembly. The buffer support is inserted into the cylindrical body through its lower end, and the quick-release connector is located outside the cylindrical body.
[0012] The preferred embodiment of the above scheme is that the buffer support is composed of a set of compression springs, the quick-release connector is fixed on the top of the compression springs, and the compression springs are inserted into the cylindrical body through their lower part.
[0013] Furthermore, the quick-release connector is a set of quick-connect plates whose geometry and size are adapted to the geometry and size of the support position of the electric actuator. The quick-connect plates are fixed on the top of the compression spring, and the electric actuator is detachably snapped onto the quick-connect plates.
[0014] The preferred embodiment of the above scheme is that the limiting installation component, the buffer support component, and the quick-release connector are all made of stainless steel.
[0015] Furthermore, the portal frame is made of channel steel, square steel or flat steel, and the circular cylinder that constitutes the limiting installation component has a split structure along the axial direction. One of the two semi-circular cylinders is fixed on the base frame assembly, and the two semi-circular cylinders are detachably connected as a whole by clamps.
[0016] The beneficial effects of this utility model are as follows: The technical solution provided in this application is based on existing multiple electric valves arranged sequentially along the length direction. Combining this with the structural characteristic that the electric actuators of each electric valve are suspended outside the corresponding vertical steam pipe, a support device is constructed by adding a base frame assembly and a support connection assembly. The support connection assembly is then movably arranged on the base frame assembly, and the electric actuators of each sequentially arranged electric valve are respectively supported on the support connection assembly. This solves the technical problem of uneven force distribution caused by the electric actuators of electric valves being suspended due to their own weight or external working forces in the prior art. With the support device of this application, the electric actuators of each electric valve are supported on the support connection assembly and are strongly supported by the base frame assembly. This eliminates the condition where the electric actuators of the electric valves are suspended in the air, thus effectively preventing the valves from jamming due to external forces acting on the electric actuators during operation. This ensures that the vertical pipeline is always in a smooth flow state, maximizes the normal operation of the energy production and supply links in liquor production, and minimizes the occurrence of safety accidents.

[0019] like Figure 1 , Figure 2 as well as Figure 3This invention illustrates a support device for vertically mounted electric valve actuators, designed to effectively prevent valve jamming caused by external forces acting on the electric actuator during operation. The support device comprises multiple electric valves arranged sequentially along the length direction, with the electric actuators of each valve suspended outside the corresponding vertical steam pipe. The support device includes a base frame assembly and a support connection assembly. The support connection assembly is movably mounted on the base frame assembly, and the electric actuators of each sequentially arranged electric valve are respectively supported on the support connection assembly. This application's technical solution is based on existing systems with multiple electric valves arranged sequentially along the length direction. Combining this with the structural characteristic of the electric actuators of each electric valve suspended outside the corresponding vertical steam pipe, the support device of this application is constructed by adding a base frame assembly and a support connection assembly. The support connection assembly is then movably mounted on the base frame assembly, and the electric actuators of each sequentially arranged electric valve are respectively supported on the support connection assembly. This invention solves the technical problem of uneven force distribution caused by the weight of the electric actuators of electric valves when they are suspended in the air, as described in the prior art. With the support device of this application, the electric actuators of each electric valve are supported on the support connection assembly and strongly supported by the base frame assembly. This eliminates the condition where the electric actuators of the electric valves are suspended in the air, effectively preventing valve jamming caused by external forces on the electric actuators during operation. This ensures that the vertical pipeline remains unobstructed, maximizes the normal operation of energy production and supply in liquor production, and minimizes the risk of safety accidents.
[0020] Accordingly, considering actual production conditions, and in order to simplify the structure as much as possible, facilitating manufacturing and installation, and integrating with the layout of vertical steam pipes, the base frame assembly of this application includes a portal frame 1 and fixing screws 2. The support connection assembly is arranged on the portal frame 1 according to the position of the electric actuators that need support. The portal frame 1 is detachably fixed to the foundation at the corresponding position via its two vertical sides and the fixing screws 2. Preferably, the portal frame 1 can be an extra-long portal frame with a horizontal side adapted to the arrangement length of each set of electric actuators, or it can be multiple small portal frames, the number of which is equivalent to the number of electric actuators that need support. The support connection assembly is detachably fixed to the foundation at the corresponding position via the extra-long portal frame or each small portal frame and the fixing screws 2.
[0021] Furthermore, as a key component of this improvement, to enhance the reliability of the support and facilitate assembly and disassembly, the support connection assembly of this application includes multiple support connection groups, the number of which is equivalent to the number of electric actuators requiring support. Each set of electric actuators is movably arranged on the base frame assembly through its respective support connection group. In this application, each support connection group is configured to include a limiting installation component 3, a buffer support component 4, and a quick-release connector 5. The quick-release connector 5 is fixed to the top of the buffer support component 4, and the buffer support component 4 is movably arranged on the base frame assembly at the corresponding position via the limiting installation component 3. More specifically, the limiting installation component 3 is composed of a cylindrical body, with its opening facing upwards at the corresponding position on the base frame assembly. The buffer support component 4 is inserted into the cylindrical body through its lower end, and the quick-release connector 5 is located outside the cylindrical body. The buffer support component 4 is composed of a set of compression springs, with the quick-release connector 5 fixed to the top of the compression springs, and the compression springs are inserted into the cylindrical body through their lower parts. The quick-release connector 5 is a set of quick-connect plates whose geometry and size are adapted to the geometry and size of the support position of the electric actuator. The quick-connect plates are fixed on the top of the compression spring, and the electric actuator is detachably snapped onto the quick-connect plates. The circular cylinder that constitutes the limiting installation component 3 has a split structure along the axial direction. One of the two semi-circular cylinders is fixed on the base frame assembly, and the two semi-circular cylinders are detachably connected into a whole by a clamp.
[0022] In accordance with the production requirements of alcoholic beverages and soft drinks, the limiting installation component 3, the buffer support component 4, and the quick-release connector 5 of this application are all made of stainless steel, and the gantry frame 1 of this application is made of channel steel, square steel, or flat steel.
[0023] In summary, the design of the electric actuator bracket provided in this application, i.e., the aforementioned support device, avoids the defects existing in the prior art, forming a physical support to ensure the normal use of the electric actuator and the normal opening and closing of the valve. It effectively prevents electric valve jamming, motor failure, and equipment safety accidents caused by steam backflow, ensuring the integrity and effectiveness of the equipment and effectively protecting the lives of on-site personnel. Specifically, 1) This support frame can effectively support the suspended part of the electric actuator of the vertically installed electric valve, preventing the valve from jamming due to uneven force, which would damage the equipment motor; 2) Solved the technical problem of boiler damage and accidents caused by internal leakage of high-temperature and high-pressure steam and backflow of steam due to improper valve opening and closing of electric actuators; 3) The support bracket uses a metal bracket with spring elements to ensure that the electric actuator is subjected to uniform force and operates stably during use; 4) Using spring elastic elements as support components helps to compensate for thermal expansion deformation caused by high-temperature fluids when multiple electric actuators are used in the energy production and supply process. 5) The support frame is easy to install and disassemble using bolts, reducing maintenance costs.
[0024] The technical solution of this application will be further described below through specific embodiments: In the energy supply of the liquor or beverage production industry, during the operation of auxiliary equipment in boiler and turbine systems, there are over 30 electric valve actuators used in the boilers and turbines at the production site. Most are installed on vertical steam pipes, with a diameter of 350mm. The electric actuators are installed perpendicular to the steam pipes. The motor portion of the electric actuator is 492mm long, 104mm high, and weighs approximately 88kg. To ensure the normal operation of the boiler and turbine systems, the electric actuators are used to drive the electric valves on and off multiple times. During on-site operation, the electric actuators are not supported, which can easily cause valve jamming, inability to open or close properly. Furthermore, improper closure can lead to backflow of high-temperature, high-pressure steam, damaging the boiler itself and potentially causing mechanical injury.
[0025] Therefore, this application addresses the above issues by using a spring and frame support, which can prevent the valve from jamming due to gravity, reduce vibration and noise generated by the electric actuator during operation, compensate for certain installation errors and deformation caused by thermal expansion and contraction, and prevent vibration from affecting the opening and closing accuracy of the electric valve.
[0026] Example 1 This application designs a metal bracket with a spring element as a support component. The support component is made of 40×70 channel steel, approximately 4mm thick, characterized by stability, high temperature resistance, and a certain degree of toughness. Combined with the spring as an elastic element, it creates elastic contact between the actuator and the bracket. The spring is fixed to the bracket, and the elastic force generated by its elastic deformation provides support for the actuator, offsetting and overcoming the additional stress on the valve components caused by the weight of the actuator, ensuring stable operation. Furthermore, the spring's deformation capacity prevents the bracket from cracking due to thermal stress. The patented support component can fit tightly with the field electric actuator equipment.
[0027] Accordingly, to facilitate subsequent maintenance and repair, the cylinder of this application is cut into two halves along the axial direction. One half is welded to the bracket. During installation, the bracket is fixed first, then the spring is slightly deformed and slides into the space between the bracket and the actuator, fitting snugly against the cylinder. Then, the other half of the cylinder is put on and fixed with a clamp to complete the installation. After installation, the bottom of the actuator relies on the spring as a support component. The split cylinder structure is adopted to facilitate disassembly during subsequent maintenance of the actuator. Of course, the split cylinder is also suitable for situations where the actuator with the electric valve is installed first and the support device is installed later.
