Abstract
Description
Technical Field
[0001] This utility model relates to an assembly and fixing component, specifically to a shut-off valve assembly and fixing component. Background Technology
[0002] A gate valve, also known as a stop valve, is a forced-seal valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to ensure a leak-proof seal. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the frictional force of the valve stem and packing, plus the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open it, so the valve stem diameter must be larger; otherwise, the valve stem may bend. Gate valves are classified into three types according to their connection method: flange connection, threaded connection, and welded connection. Since the advent of self-sealing valves, the flow direction of the medium in gate valves has changed to entering the valve cavity from above the valve disc. In this case, under the action of the medium pressure, the force required to close the valve is smaller, while the force required to open it is larger, allowing for a corresponding reduction in the valve stem diameter. Simultaneously, this type of valve is also more airtight under the action of the medium. my country's valve standardization regulations once stipulated that the flow direction of gate valves should always be from top to bottom. When a gate valve is opened, the flow rate reaches its maximum when the valve disc opening height is 25%-30% of the nominal diameter, indicating that the valve is fully open. Therefore, the fully open position of the gate valve should be determined by the travel of the valve disc.
[0003] During the processing and assembly of gate valves, in order to facilitate operation and avoid the omission or misalignment of parts during assembly, it is necessary to temporarily fix the valve body or accessories, but it is not possible to move them for assembly or maintenance. In view of this, this application designs a gate valve assembly and fixing component. Utility Model Content
[0004] The main objective of this disclosure is to provide a shut-off valve assembly and fixing component to effectively solve the problems raised by the inventors in the aforementioned background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A shut-off valve assembly and fixing component includes an assembly platform. A first pressure sensor, evenly distributed across its top, is mounted on the top of the assembly platform. A load-bearing mounting base is mounted on the top of the assembly platform, and the detection end of the first pressure sensor is connected to the load-bearing mounting base. An assembly movable groove is formed on the top of the load-bearing mounting base, and a positioning assembly plate is fixedly installed within the assembly movable groove. A movable assembly plate is movably installed within the assembly movable groove. Clamping slots are formed on the sides of the positioning assembly plate and the movable assembly plate that are close to each other, and clamping slots are used to install clamping assemblies for external devices.
[0007] Preferably, an X-axis slide is fixedly installed in the assembly slot, and the movable assembly plate is slidably installed on the X-axis slide, with the X-axis slide passing through the positioning assembly plate.
[0008] Preferably, an X-axis one-way lead screw is rotatably installed in the assembly slot, and the X-axis one-way lead screw is arranged parallel to the X-axis sliding shaft. A movable assembly plate is threaded onto the X-axis one-way lead screw. A second servo motor is fixedly installed on the side of the load-bearing mounting base, and the output shaft of the second servo motor is fixedly connected to the X-axis one-way lead screw.
[0009] Preferably, a Y-shaped frame is fixedly installed on the top of the assembly table, and a flat plate sleeve is rotatably installed on the Y-shaped frame. The flat plate sleeve has a limit hole. A first servo motor is fixedly installed on the side of the Y-shaped frame, and the output shaft of the first servo motor is fixedly connected to the flat plate sleeve. A notch is opened on the top of the load-bearing mounting base, and a sleeve post is fixedly installed in the notch. A pressure plate is slidably installed on the sleeve post, and a return spring is fixedly connected between the pressure plate and the bottom wall of the notch. A second pressure sensor is evenly distributed on the top of the pressure plate. The size of the limit hole is larger than the size of the sleeve post and smaller than the size of the pressure plate.
[0010] Preferably, a PLC controller is fixedly mounted on the positioning assembly plate, and the first pressure sensor, the second pressure sensor, the first servo motor, and the second servo motor are all electrically connected to the PLC controller.
[0011] Preferably, the bottom of the assembly table is fixedly equipped with a number of evenly distributed table legs.
[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:
[0013] (i) In this application, the peripheral gripper assembly is used to grip the assembly parts of the gate valve, and the gripper assembly on the positioning assembly plate is used to fix the parts, while the gripper assembly on the moving assembly plate is used to drive the parts to move and realize assembly. During assembly, the second servo motor works, which drives the X-axis one-way screw to rotate, and the moving assembly plate moves along the X-axis sliding axis toward the positioning assembly plate. The operation is simple and fast, and it is suitable for the assembly or maintenance of gate valves.
[0014] (II) In this application, after the shut-off valve accessory is clamped, the weight of the load-bearing mounting base increases. After the first pressure sensor detects the increase in pressure value, it causes the PLC controller to control the first servo motor to start. The first servo motor then drives the flat plate sleeve to rotate, so that the sleeve column is inserted into the limiting hole, thus fixing the load-bearing mounting base. The flat plate sleeve then squeezes the second pressure sensor. The second pressure sensor detects the pressure, so that the PLC controller controls the second servo motor to work, so that the moving assembly plate drives the shut-off valve or accessory to move, thereby achieving the purpose of automatic assembly and improving work efficiency.

Several evenly distributed platform legs 7 are fixedly installed on the bottom of the assembly platform 1.
[0024] Specifically, an X-axis slide shaft 8 is fixedly installed in the assembly slot, and a movable assembly plate 5 is slidably installed on the X-axis slide shaft 8. The X-axis slide shaft 8 passes through the positioning assembly plate 4. An X-axis one-way screw 9 is rotatably installed in the assembly slot, and the X-axis one-way screw 9 is parallel to the X-axis slide shaft 8. The movable assembly plate 5 is threaded onto the X-axis one-way screw 9. A second servo motor 10 is fixedly installed on the side of the load-bearing mounting base 3, and the output shaft of the second servo motor 10 is fixedly connected to the X-axis one-way screw 9.
[0025] Specifically, a Y-shaped frame 16 is fixedly installed on the top of the assembly table 1, and a flat plate sleeve 17 is rotatably installed on the Y-shaped frame 16. A limit hole 18 is opened on the flat plate sleeve 17. A first servo motor 19 is fixedly installed on the side of the Y-shaped frame 16, and the output shaft of the first servo motor 19 is fixedly connected to the flat plate sleeve 17. A notch is opened on the top of the load-bearing mounting base 3, and a sleeve post 12 is fixedly installed in the notch. A pressure plate 13 is slidably installed on the sleeve post 12, and a return spring 15 is fixedly connected between the pressure plate 13 and the bottom wall of the notch. A second pressure sensor 14 is evenly distributed on the top of the pressure plate 13. The size of the limit hole 18 is larger than the size of the sleeve post 12 and smaller than the size of the pressure plate 13.
[0026] Specifically, a PLC controller 11 is fixedly installed on the positioning assembly plate 4, and the first pressure sensor 2, the second pressure sensor 14, the first servo motor 19, and the second servo motor 10 are all electrically connected to the PLC controller 11.
