Utility Model Content

[0005] The purpose of this application is to address the above-mentioned technical problems and provide a solenoid valve flow regulator that can adjust the inlet pressure and outlet flow to specified values ​​and improve the accuracy of the solenoid valve.

[0006] The present application provides a solenoid valve flow regulator, comprising:

[0007] A workbench provided with a clamping seat;

[0008] The inlet pipe is placed on the clamping seat;

[0009] The outlet pipe is placed on the clamping seat;

[0010] Solenoid proportional valve, installed on the inlet pipe;

[0011] Control system, used to adjust the air pressure of the inlet pipe and the flow rate of the outlet pipe;

[0012] Wherein, the clamping seat includes a fixed seat, a movable seat, and a first driving cylinder. The first driving cylinder is placed between the fixed seat and the movable seat. The inlet pipe is placed on the fixed seat, and the outlet pipe is placed on the movable seat.

[0013] The clamping seat is placed on the workbench, and the solenoid valve that needs to be adjusted is clamped and fixed by the clamping seat, so that the inlet of the solenoid valve corresponds to the inlet pipe, and the outlet of the solenoid valve corresponds to the outlet pipe. The fixed seat is fixed on the workbench by fasteners, and the movable seat and the fixed seat are movably connected. The relative movement between the movable seat and the fixed seat is controlled by the first driving cylinder. The solenoid valve is fixed by the fixed seat and the movable seat. After the adjustment is completed, the clamping of the solenoid valve is released by the first driving cylinder, and the inlet pipe is connected to the air source. Gas is introduced into the inlet pipe through the air source, and the air pressure at the inlet pipe is controlled by the electromagnetic proportional valve. The set pressure value of the electromagnetic proportional valve is controlled by the control system, and the flow rate of the outlet pipe is detected and controlled at the same time, thereby improving the convenience of control and adjusting the inlet pressure and outlet flow of the solenoid valve to the specified values.

[0014] Furthermore, the control system includes:

[0015] Control panel, mounted on the workbench;

[0016] A controller, mounted on the workbench and connected to the control panel;

[0017] Pressure sensor, installed in the inlet pipe;

[0018] Flow sensor, installed in the outlet pipe;

[0019] Wherein, the pressure sensor and the flow sensor are both connected to the controller, and the first driving cylinder is connected to the controller.

[0020] The control panel is used to improve the convenience of control system operation. The control panel is used to set the solenoid valve to adjust the required inlet pressure and outlet flow. The setting values ​​on the control panel are input into the controller for calculation and analysis. The pressure sensor is used to detect the electromagnetic proportional control valve to ensure that the inlet pressure of the inlet pipe is maintained at the preset value. The outlet flow rate of the outlet pipe is detected by the flow sensor. The values ​​detected by the pressure sensor and the flow sensor are transmitted to the controller to facilitate the control calculation and analysis of the controller. The sensing part of the pressure sensor is placed in the inlet pipe, and the remaining parts are extended outward and placed outside the inlet pipe. The sensing part of the flow sensor is placed in the outlet pipe, and the remaining parts are extended outward and placed outside the outlet pipe.

[0021] Furthermore, the control system further includes:

[0022] Movable seat, movably installed on the workbench;

[0023] The stepper motor is mounted on the movable seat;

[0024] Adjusting wrench, installed on the output shaft of the stepper motor;

[0025] The second driving cylinder is placed between the movable seat and the workbench;

[0026] Wherein, the second driving cylinder and the stepping motor are both connected to the controller.

[0027] When the solenoid valve is clamped by the clamping seat, the movable seat is controlled to move by the second driving cylinder, and the stepper motor and the adjusting wrench installed on the movable seat move at the same time, so that the adjusting wrench cooperates with the adjusted valve seat on the solenoid valve. When the controller calculates the values ​​detected by the pressure sensor and the flow sensor, it controls the rotation of the stepper motor to adjust the solenoid valve by the adjusting wrench, and controls the inlet pressure and outlet flow of the solenoid valve to meet the specified values.

[0028] Furthermore, the adjusting wrench includes:

[0029] The wrench head is used to correspond to the valve seat on the solenoid valve;

[0030] Adjustment seat, placed on the adjustment plate hand;

[0031] The movable block is placed at one end of the wrench head;

[0032] A spring is placed between the adjusting seat and the movable block;

[0033] Wherein, the adjustment seat is provided with a first tooth portion, and the movable block is provided with a second tooth portion, and the first tooth portion corresponds to the second tooth portion.

[0034] The wrench head corresponds to the valve seat on the solenoid valve, and the adjusting wrench needs to be matched with the valve seat before adjustment. During the downward movement of the adjusting wrench, the wrench head is first matched with the valve seat through the movable connection between the adjusting seat and the movable block. As the adjusting wrench continues to move downward, the first tooth portion is matched with the second tooth portion, ensuring that when the adjusting wrench is rotated, the wrench head can be controlled to rotate at the same time to achieve adjustment of the valve seat. The first tooth portion and the second tooth portion both adopt end face gear rings. When the adjusting wrench is separated from the solenoid valve, the first tooth portion and the second tooth portion are separated by the action of the spring, which is convenient for subsequent matching use.

[0035] Furthermore, the clamping seat is provided with a sealing member, and the sealing member is placed at the pipe openings of the inlet pipe and the outlet pipe.

[0036] The sealing between the solenoid valve and the inlet pipe and outlet pipe is improved by the sealing member to ensure the adjustment accuracy of the solenoid valve.

[0037] Furthermore, the workbench is provided with a start button, and the start button is connected to the control system.

[0038] After the solenoid valve is placed on the fixed seat, the start button is pressed to control the clamping seat to clamp the solenoid valve, and then the solenoid valve inflation test and adjustment are started, which has high automation performance.

[0039] The beneficial effects of this application are:

[0040] 1. Introduce gas into the inlet pipe through the gas source, and control the gas pressure at the inlet pipe through the electromagnetic proportional valve.

[0041] 2. The control system controls the set pressure value of the electromagnetic proportional valve and detects the flow rate of the outlet pipe for control, thereby improving the convenience of control.

[0042] 3. The pressure sensor is used to detect the electromagnetic proportional control valve to ensure that the inlet pressure of the inlet pipe is maintained at the preset value, and the outlet flow rate of the outlet pipe is detected by the flow sensor. BRIEF DESCRIPTION OF THE DRAWINGS

The first driving cylinder 113 is placed between the fixed seat 111 and the movable seat 112. The inlet pipe 200 is placed on the fixed seat 111, and the outlet pipe 300 is placed on the movable seat 112.

[0058] The clamping seat 110 is placed on the workbench 100, and the solenoid valve to be adjusted is clamped and fixed by the clamping seat 110, so that the inlet of the solenoid valve corresponds to the inlet pipe 200, and the outlet of the solenoid valve corresponds to the outlet pipe 300. The fixed seat 111 is fixed on the workbench 100 by fasteners, and the movable seat 112 is movably connected to the fixed seat 111. The relative movement between the movable seat 112 and the fixed seat 111 is controlled by the first driving cylinder 113. The solenoid valve is fixed by the fixed seat 111 and the movable seat 112. After the adjustment is completed, the clamping of the solenoid valve is released by the first driving cylinder 113, and the inlet pipe 200 is connected to the air source. Gas is introduced into the inlet pipe 200 through the air source, and the air pressure at the inlet pipe 200 is controlled by the electromagnetic proportional valve 400. The set pressure value of the electromagnetic proportional valve 400 is controlled by the control system 500. At the same time, the flow rate of the outlet pipe 300 is detected for control, thereby improving the convenience of control and adjusting the inlet pressure and outlet flow of the solenoid valve to the specified values.

[0059] Example 2:

[0060] like Figure 1-Figure 3 As shown, the embodiment of the present application provides a solenoid valve flow regulator. In addition to the above technical features, the control system 500 further includes:

[0061] A control panel 510 is mounted on the workbench 100;

[0064] Flow sensor 530, installed in outlet pipe 300;

[0065] The pressure sensor 520 and the flow sensor 530 are both connected to the controller, and the first driving cylinder 113 is connected to the controller.

[0066] The control panel 510 is used to improve the convenience of operating the control system 500. The control panel 510 is used to set the solenoid valve to adjust the required inlet pressure and outlet flow. The setting values ​​on the control panel 510 are input into the controller for calculation and analysis. The pressure sensor 520 is used to detect the electromagnetic proportional control valve to ensure that the inlet pressure of the inlet pipe 200 is maintained at a preset value. The flow sensor 530 is used to detect the outlet flow rate of the outlet pipe 300. The values ​​detected by the pressure sensor 520 and the flow sensor 530 are transmitted to the controller to facilitate the control calculation and analysis of the controller. The sensing part of the pressure sensor 520 is placed in the inlet pipe 200, and the remaining part extends outward and is placed outside the inlet pipe 200. The sensing part of the flow sensor 530 is placed in the outlet pipe 300, and the remaining part extends outward and is placed outside the outlet pipe 300.

[0073] After the solenoid valve is clamped by the clamping seat 110, the movable seat 540 is controlled to move by the second driving cylinder 570, and the stepper motor 550 and the adjusting wrench 560 installed on the movable seat 540 move at the same time, so that the adjusting wrench 560 cooperates with the adjusted valve seat on the solenoid valve. After the controller calculates the values ​​detected by the pressure sensor 520 and the flow sensor 530, it controls the stepper motor 550 to rotate, so that the adjusting wrench 560 adjusts the solenoid valve, and controls the inlet pressure and outlet flow of the solenoid valve to meet the specified values.

[0074] Furthermore, the adjusting wrench 560 includes:

[0075] The wrench head 561 is used to correspond to the valve seat on the solenoid valve;

As the adjusting wrench 560 continues to move downward, the first tooth portion 565 is cooperated with the second tooth portion 566 to ensure that when the adjusting wrench 560 is rotated, the wrench head 561 can be controlled to rotate at the same time to achieve adjustment of the valve seat. The first tooth portion 565 and the second tooth portion 566 both adopt end face gear rings. When the adjusting wrench 560 is separated from the solenoid valve, the first tooth portion 565 and the second tooth portion 566 are separated by the action of the spring 564, which is convenient for subsequent cooperation.
