Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, and in particular to a valve for a DCS system switching actuator. Background Technology
[0002] DCS systems, or Distributed Control Systems, are a key technology in industrial automation. Based on microprocessors, DCS systems are a new generation of instrumentation and control systems that employ distributed control functions, centralized display and operation, and a design principle that balances distributed autonomy with comprehensive coordination. They feature distributed deployment and centralized control, making them applicable to various process automation control systems. The switching actuator is a crucial component of this automation control system, acting as the actuator. It receives control signals from controllers (such as DCS and PLC) and converts these signals into mechanical actions, thereby achieving precise control over parameters such as flow rate, position, or force of the process medium. In DCS systems, switching actuators are typically used to control the on / off states of equipment, such as valve opening and closing, and motor starting and stopping. In industrial production processes, such as chemical, petroleum, power, and pharmaceutical industries, precise control of parameters such as flow rate, pressure, and temperature of various process media (such as liquids, gases, and steam) is required. These control needs often involve the on / off states of valves, such as opening or closing valves to regulate the flow rate or pressure of the medium. Therefore, switching actuators and valves in DCS systems play a vital role in these industries.
[0003] In the case of conveying liquids, the existing valves have a fast flow rate at the flow connection and no buffer structure is set up. The flow rate of the liquid cannot be buffered and reduced. When the control switch is turned on, the fast flow rate of the liquid may affect the subsequent conveying operation and may easily damage the conveying pipeline.
[0004] Therefore, it is necessary to provide a new valve for DCS system switching actuators to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a valve for a DCS system switch actuator.
[0006] The valve for a DCS system switching actuator provided by this utility model includes:
[0007] A conveying pipe, with a valve body fitted on one side of the conveying pipe;
[0008] The valve structure includes a valve body, a rotary motor, and a butterfly valve. The top of the valve body is fixedly connected to a rotary motor, and there are two sets of rotary motors. The top of the delivery pipe and the valve body are provided with through holes. The output ends of both sets of rotary motors pass through the through holes into the interior of the delivery pipe. The output ends of both sets of rotary motors are fixedly connected to butterfly valves.
[0009] The buffer structure includes a connecting pipe, a buffer pipe, and a buffer plate. The connecting pipe is connected to and fixedly connected to the rear side of the conveying pipe. There are two sets of connecting pipes. The rear sides of the two sets of connecting pipes are connected to and fixedly connected to the buffer pipe. The inner wall of the buffer pipe is fixedly connected to the buffer plate. There are multiple sets of buffer plates arranged alternately.
[0010] Preferably, connecting rings are fixedly connected to both sides of the delivery pipe, and the valve can be aligned with the pipe through the connecting rings.
[0011] Preferably, the connecting ring has multiple sets of connecting holes, and the valve can be installed onto the pipeline by bolts through these connecting holes.
[0012] Preferably, a guide plate is fixedly connected to the internal connection point on one side of the connecting pipe, which can prevent liquid from flowing back into the buffer pipe.
[0013] Preferably, sealing rings are fitted on both sides of the butterfly valve, which can enhance the valve's sealing performance.
[0014] Preferably, the two sets of rotary motors can be controlled independently, and the valves can be easily adjusted by setting independently controlled rotary motors.
[0015] Preferably, a controller is fixedly connected to the front side of the valve body, and a power cord is fixedly connected to one side of the controller, so that the valve can be operated intuitively through the controller.
[0016] Preferably, the rotary motor is electrically connected to the controller via wires, and power and control signals can be transmitted to various electronic components via the wires.
[0017] Compared with related technologies, the valve for DCS system switching actuators provided by this utility model has the following advantages:
[0018] 1. This utility model can control the flow of liquid through the set valve structure. When using the valve, the controller on the valve can be operated uniformly by the DCS system switch actuator. The controller controls the output ends of two sets of rotary motors to rotate, which drives the butterfly valve fixedly connected to the lower end of the output end to rotate. The rotation of the butterfly valve allows the liquid to flow, thereby realizing the control of the flow of liquid through the valve.
[0019] 2. This utility model can reduce the flow rate of liquid through the set buffer structure. When using the valve to make the liquid flow, the controller on the valve can be uniformly operated by the DCS system switch actuator. The controller controls the output end of the rotary motor on one side to rotate, which drives the butterfly valve fixedly connected to the lower end of the output end to tilt, guiding the flowing liquid to the connecting pipe behind the delivery pipe. The liquid flows to the buffer pipe through the connecting pipe. The liquid flows to the buffer pipe, and the multiple sets of buffer plates inside the buffer pipe slow down the flow rate of the liquid. It then flows out through the connecting pipe on the other side, thereby reducing the flow rate of the high-speed liquid. Attached Figure Description
