Test Principle
1. Thermoelectric solenoid valve shut-off current test (implemented in the "CJ/T30-2013 Thermoelectric Appliance Flameout Protection Device" standard "2013.10.1", which cancels valve opening current definition and testing):

◆ Touchscreen controls a self-made constant current source, outputs the required current according to the beat, and automatically tests it

◆ Open/close valve detection: Introduce compressed air at 1.5-4.5 KPa (pre-tuned) at the inlet, output port detection capability, and determine whether the valve is open/closed

◆ According to Standard 7.6.3.2 of the "CJ/T30-2013 Thermoelectric Appliance Flameout Protection Device" requirements:
a) apply a specified torque or operating force to the knob or button (manually operated) to activate the closing element of the flameout protection device

b. (Press the start button) Use current to activate the magnetic element, maintaining a constant speed of no more than 30mA/s

Increase the current. Up to 300% of the manufacturer's declared shut-off current

C. Release the knob or button (manually manual) to set the flameout protection device below fully open, and the device will operate automatically

d) Increase the current to 1500mA at any speed, maintaining at least 60 seconds
e) Reduce the current at a constant speed to reach the manufacturer's stated closing current of 300 seconds
f) Then lower the current at a constant speed not exceeding 10mA until the shutdown device closing element closes
g) ) Test the current value at
this point h) Repeat the above steps 10 times, Take the average of the measured shut-off current values to serve as the closing valve current value.

2. Valve body contact resistance test: clamp the test clip of the built-in low-resistance detector into the appropriate position. Once the data stabilizes, press the button to store the data.

3. Airtightness Test:

◆ Thermoelectric solenoid valve airtightness: Connect the airtightness leak detector to the valve body inlet, open the valve body outlet, and press the knob

Then rotate to the conical valve opening position, press the button to start and test the solenoid valve's airtightness, and the data will be automatically saved.

◆ Cone valve airtightness: Apply 300% of the manufacturer's declared shut-off current to the thermoelectric solenoid valve, press the knob, then release to keep the valve fully open and the cone valve closed. Press the button to start and test the cone valve's airtightness, with data automatically saved

◆ Connect the airtight leak detector to the valve body inlet: Introduce the thermoelectric solenoid valve with a current of 300% of the manufacturer's declared closing current, press the knob and release to keep the thermoelectric solenoid valve fully open and the cone valve closed. Press the button to start testing the overall valve body airtightness, and the data will be automatically saved

4. Valve stem torque test: Use a graduated torque screwdriver. The front part of the screwdriver uses a homemade chuck, which is fitted with the valve stem and tested directly. After reading the value from the dial, the touchscreen can display the value.

Frequently Asked Questions

What industries is your company's testing equipment mainly suitable for?

We specialize in non-standard testing equipment for gas appliances and household appliances, especially in the gas appliance industry, with nearly thirty years of technical accumulation in the gas appliance industry, including gas water heaters, wall-hung boilers, and gas stoves. At the same time, the equipment is widely used in kitchen appliances such as range hoods, electric ovens, and sterilizers, as well as in environmental reliability testing fields like salt spray tests and high and low temperature tests. In addition, industrial automation inspection solutions can be customized according to customer requirements.

Do you make standard equipment or non-standard customization?

Focusing mainly on non-standard customs. Each production line and every product category has unique testing requirements. We provide a full range of customized services from solution design, mechanical manufacturing, electrical control, to software integration based on your inspection targets (such as valve bodies, complete machines), inspection items (performance, aging, lifespan), production line cycles, and environmental conditions. There are already numerous successful non-standard cases in the gas appliance and home appliance industries for reference.

How is the precision and stability of the equipment? How to verify it?

Before leaving the factory, we conduct complete machine testing and precision calibration according to national or industry specifications, and can provide actual measurement data reports. Common verification methods include: repeated testing with standard samples, comparison with customers' existing qualified equipment, or testing by third-party metrology agencies. For key parameters such as gas flow, pressure, and temperature, we also provide calibration recommendations and cycle reminders. For projects requiring extremely high precision, free sample testing can be arranged.

How long does it take to customize a device? Will it affect my production?

The project duration depends on the complexity of the equipment, generally 4~8 weeks, and includes requirements confirmation, solution design, manufacturing, factory pre-commissioning, and on-site installation. We complete pre-assembly and functional testing of the entire machine in the factory, and only a short time of wiring and fine-tuning can be done on site for trial operation. We will communicate with you in advance about the production shutdown window and develop a detailed installation schedule to minimize the impact on production.

Is the equipment complex to operate? What training do you offer?

The equipment uses a touchscreen human-machine interface, with simple operation logic; ordinary workers can use it daily after half a day of training. We offer tiered training: operator training (power on/off, data retrieval, fixture change), technician training (parameter adjustment, simple fault handling), and engineer training (system configuration, deep maintenance). It also provides a library of operation videos and illustrated manuals for easy access at any time.
