Description

Technical Field

[0001] The utility model relates to a measuring and controlling device for a ground air path system of an ejection mechanism. Background Art

[0002] Due to the need for the push-out function test and airtightness test in the ground test of the push-out mechanism, it is required to be able to quickly and accurately provide high-pressure gas to the push-out mechanism and to quickly extract test data. Due to the imperfection of the test device, it is often impossible to ensure the speed and accuracy of the high-pressure gas providing pressure, and it is impossible to directly collect test data such as the push-out time. Therefore, a test device that can electrically control the output of high-pressure gas, directly collect test data such as the push-out time, and react quickly is needed to meet the above requirements. For example, CN115893649A discloses a MABR integrated device and method for treating aerospace wastewater. The pressure, flow rate and water quality of the gas / liquid of each part of the system are monitored in real time through a PLC control system. The monitoring equipment data is transmitted to the PLC control device. The PLC device comprehensively analyzes and adjusts the switches of the controlled equipment based on the data feedback; and realizes accurate control of the oxygen supply pressure and data collection. However, it does not simplify the structure of the control device and the gas circuit, making its circuit complicated and unfavorable for installation and subsequent maintenance.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0024] A measurement and control device for a ground air path system of an ejection mechanism; a piping system 1, a frame 2, and a control box 3, wherein the piping system 1 includes a pressure reducing valve assembly 15, a filter 14, a second four-way valve 32, a stop valve 11, a solenoid valve 10, a first four-way valve 4, and a digital pressure gauge 5 connected in sequence, wherein the filter 14, the second four-way valve 32, the stop valve 11, and the solenoid valve 10 are installed in the frame 2, and the pressure reducing valve assembly 15 and the first four-way valve 4 are both arranged outside the frame 2. A digital pressure gauge 5 is installed on one interface of the first four-way valve 4, and the other two interfaces are respectively connected to the device under test and the pressure sensor, the control box 3 is fixed to the top of the frame 2, and a delay relay 20, a power supply 21, a resistor 22, and a timer 24 are installed in the control box 3. A terminal 7, a button switch 13, and a timer 24 are installed on the top of the control box 3, and the digital pressure gauge 5 and the solenoid valve 10 are respectively connected to the terminal 7 through wires.

[0025] like Figure 2As shown, the pressure reducing valve assembly 15 of the pipeline system 1 is equipped with a pressure gauge, which can simultaneously detect the gas source pressure and regulate the output pressure. The filter 14 can filter water vapor from the high-pressure gas entering the gas system to ensure that the high-pressure gas is dry. The opening and closing of the two stop valves 11 and the four-way valve 4 can realize the gas system opening, pressure maintenance, and pressure relief functions. The solenoid valve 10, a four-way valve 4, the filter 14, the stop valve 11, etc. in the pipeline system 1 are connected to the vehicle frame 2 via screws. The installation position of the stop valve 11 is spray-painted with opening and closing instructions. The pressure reducing valve assembly 15, a four-way valve 4, a digital pressure gauge 5, and a metal hose 18 are external to the vehicle frame 2. The pressure reducing valve assembly 15 is connected to the external gas source. The four-way valve 4 has four interfaces for gas supply to the gas system, connection to the device under test, connection to the digital pressure gauge 5, and a reserved pressure sensor interface. The digital pressure gauge 5 can monitor pressure changes within the system in real time and, in conjunction with the stop valve 11, can perform airtightness checks on the device under test. The piping system 1 is divided into metal hoses 18 and metal rigid tubes 16. The metal rigid tubes 15 are used to connect components installed inside the vehicle frame 2, improving the stability and airtightness of the air system. The metal hoses 18 are used to connect components installed outside the vehicle frame 2, improving operability when connecting to other devices. The control box 3 is designed with a power supply 21 that can be connected to 220V AC power and output 24V DC power. This, in conjunction with the toggle switch 13 and terminal 7 installed on the control box 3, controls the on / off power supply to the solenoid valve 10, thereby electrically controlling the opening of the air system. The control box 3 is also designed with a timer 24, which is directly powered by the 24V DC power generated by the control box 3. Timer 24 begins counting when the control box 3 signals the solenoid valve 10 to turn on, and stops counting when the device under test signals the on / off signal. This can be used in conjunction with electronic components such as microswitches and proximity switches on the device under test to measure data such as movement time and ventilation time. The load-bearing structure in the frame 2 is welded from high-strength aluminum alloy, which ensures structural strength while reducing the weight of the structure. Two universal wheels 25 and a universal wheel 8 with brakes are installed in the frame 2, which can realize the movement and stop of the equipment. An installation interface of the control box 3 is designed in the frame 2. The control box 3 is installed on the top of the frame 2 by screws, which is convenient for equipment transportation. At the same time, the installation height is convenient for personnel to operate the control box 3 during testing.

[0026] The working process of the test device is as follows: connect the pressure reducing valve assembly 15 to the external air source, connect the power supply cable of the solenoid valve 10 to the corresponding terminal 7 on the control box 3, and connect the two reserved interfaces of the four-way 4 to the device under test and the pressure sensor respectively through pipe joints. If there is no pressure sensor, use a plug to block the corresponding interface, adjust the two stop valves 11 to ensure that the airflow can be correctly connected to the solenoid valve 10 and will not be directly discharged, connect the time measurement corresponding terminal 7 on the control box to the micro switch of the device under test, and after ensuring that the equipment is connected normally, power the control box 3, turn on the external air source, and adjust the output pressure to a predetermined value by adjusting the pressure reducing valve assembly 15. By toggling the corresponding button switch 13 on the control box 3, power is supplied to the solenoid valve 10, the solenoid valve 10 is turned on, and the timer 24 starts timing. The high-pressure gas passes through and enters the device under test. The device under test moves to the specified position under the action of the high-pressure gas, and the micro switch on the device under test feeds back a position signal to the control box 3, the timer stops timing, and the air supply push test of the device under test is completed. Close the pressure reducing valve assembly 15 and observe the digital pressure gauge 5. After the pressure stabilizes, perform an airtightness test on the equipment under test. After a period of time, the airtightness of the equipment under test can be judged by the pressure change of the digital pressure gauge 5. After the test is completed, adjust the stop valve 11 to allow the high-pressure gas to pass through the four-way 4 and one of the stop valves 11 to be discharged from the system. After the gas is discharged, close the solenoid valve 10.

[0027] like Figure 8 As shown, the pipe joint 17 includes four groups of connection terminals: terminal X pipeline system 1, terminal X frame 2, terminal X control box 3, and terminal X first four-way 4.

The other end of the contact of the delay relay 20 is connected to the positive electrode of the terminal X frame 2, and the other end of the toggle switch S pipeline system 1 is connected to the toggle switch S control box 3. The toggle switch S control box 3 is installed between the terminal X first four-way 4 and the power supply 21.
