Description

Technical Field

[0001] This utility model relates to the field of fluid control valve technology, and in particular to a modular stacked valve with intelligent pressure regulation function. Background Technology

[0002] Modular stack valves are integrated hydraulic components that combine multiple hydraulic functional units (such as pressure control, flow control, and directional control) through standardized interfaces. They are widely used in industrial automation, machine tools, and construction machinery.

[0003] In fluid control systems, valves are used to regulate the flow and pressure of the medium. Some existing valves may face some problems during long-term use. Impurities carried in the medium may enter the valve and cause wear or blockage of internal components, affecting the valve's lifespan and the stability of system operation. At the same time, these valves often do not regulate the medium pressure accurately enough, requiring frequent manual intervention and adjustment, which is inefficient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as impurities carried by the medium entering the valve, which may cause wear or blockage of internal components, affecting valve life and system stability. At the same time, these valves often do not regulate the medium pressure accurately enough, requiring frequent manual intervention and adjustment, which is inefficient. The proposed invention is a modular stacked valve with intelligent pressure regulation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular stacked valve with intelligent pressure regulation function includes a valve body, a connecting frame fixedly mounted on the front side of the valve body, a control box fixedly mounted on the connecting frame, a controller inside the control box and heat dissipation holes on both sides, an inlet end and an outlet end respectively provided at both ends of the valve body, a filter assembly for filtering the medium is provided on the inlet end of the valve body, and a regulating mechanism for regulating the pressure of the medium is provided on the valve body.

[0007] In one possible design, the regulating mechanism includes a motor, a connecting pipe, and a pressure sensor. The bottom end of the motor is fixedly mounted on the top of the valve body by bolts, and its output end is fixedly connected to the control end of the valve body. One end of the connecting pipe is located at the liquid outlet. The pressure sensor is fixedly mounted on the connecting pipe for monitoring the pressure of the medium inside the connecting pipe. Both the motor and the pressure sensor are electrically connected to the controller via wiring.

[0008] In one possible design, the filter assembly includes a second connecting pipe, a filter screen, and an observation window. One end of the second connecting pipe is fixedly connected to the liquid inlet. The outer side of the filter screen is fixedly connected to the inner wall of one end of the second connecting pipe for filtering impurities in the medium. The observation window is located on the front side of the second connecting pipe for observing the impurities filtered out by the filter screen.

[0009] In one possible design, one end of the connecting pipe two is fixedly connected to a connecting ring that is easy to disassemble and assemble. The inner wall of the connecting ring is provided with a threaded groove three. The outer side of the liquid inlet end of the valve body is provided with a threaded groove four that matches the threaded groove three. The connecting ring is threaded onto the liquid inlet end and is provided with a sealing ring for sealing.

[0010] In one possible design, the outlet end of the valve body is fixedly connected to flange one, and one end of the connecting pipe one is fixedly connected to flange four. Both flange one and flange four are fixedly connected to the same flow meter by bolts. Flange two and flange three, which are adapted to flange one and flange four, are respectively provided at both ends of the flow meter. Flange one and flange four are threadedly connected to flange two and flange three by bolts, and both are provided with rubber rings for sealing.

[0011] In one possible design, one end of the connecting pipe 2 is fixedly connected to the connecting pipe 3, and the outer side of one end of the connecting pipe 1 and the outer side of the connecting pipe 3 are respectively provided with threaded groove 1 and threaded groove 2 to facilitate connection with external pipes.

[0012] In this application, during operation, the medium enters from the inlet end of the valve body. During the entry process, the filter assembly installed at the inlet end plays its role. The filter screen inside the connecting pipe 2 is tightly attached to the inner wall of one end of the connecting pipe 2 to intercept impurities in the medium and achieve filtration. At the same time, the observation window set on the front side of the connecting pipe 2 allows the staff to intuitively view the impurities filtered by the filter screen, so as to understand the filtration status of the filter screen in a timely manner and decide whether the filter screen needs to be cleaned or replaced.

[0013] The filtered medium enters the valve body and then flows out from the outlet. At the outlet, the pressure sensor at the first end of the connecting pipe starts to work. The pressure sensor has a sensitive element inside. When the medium flows through the first connecting pipe, the medium pressure acts on the sensitive element, causing it to deform or generate a change in electrical signal. The pressure sensor converts this change into an electrical signal corresponding to the medium pressure and transmits it to the controller in the control box through the line.

[0014] After receiving the electrical signal from the pressure sensor, the controller compares and analyzes it with the preset pressure value. If the current medium pressure does not match the preset value, the controller will send a command to the motor according to the preset program. The motor is fixed on the top of the valve body, and its output end is connected to the control end of the valve body. After receiving the command, the motor runs, driving the internal structure of the valve body to move, changing the flow area of ​​the internal channel of the valve body or the medium flow path, thereby realizing the regulation of the medium pressure until the medium pressure reaches the preset value.

[0015] In addition, a flow meter is installed between the outlet end of the valve body and the connecting pipe. When the medium flows through the flow meter, the measuring component inside the flow meter will measure the flow rate of the medium based on the physical effects generated by the flow of the medium (such as differential pressure, rotation speed, etc.). The flow meter will transmit the measured flow signal to the controller through the line, so that the staff can monitor the flow rate of the medium.

[0016] Connecting pipe 2 is fixedly connected to connecting pipe 3 at one end. Threaded groove 1 and threaded groove 2 are respectively opened on the outer side of connecting pipe 1 and connecting pipe 3, which facilitates the connection of the modular stack valve to the external pipeline. The threaded connection method is simple to operate and has a firm connection, which can ensure the stable flow of the medium between the pipeline and the stack valve.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this invention, the filter assembly intercepts impurities in the medium, preventing them from entering the valve body and causing wear or blockage, thus extending the service life of the valve body and related components. At the same time, it ensures the purity of the medium and improves the operational stability of the entire system. The observation window design allows staff to monitor the filtration status of the filter screen at any time, facilitating timely maintenance, reducing system failures caused by filter screen blockage, and improving work efficiency.

[0019] The pressure sensor in the regulating mechanism can monitor the medium pressure in real time and accurately, and transmit the signal to the controller. The controller controls the motor to operate according to the preset program, realizing intelligent regulation of the medium pressure. This intelligent regulation method has a fast response speed and high regulation accuracy, which can ensure that the medium pressure is always stable within the preset range and meet the requirements of different working conditions for medium pressure.
