Go to the special equipment inspection and testing institute for testing.

The Special Equipment Inspection and Testing Institute (in some areas is the Special Equipment Supervision and Inspection Institute) is a public institution within the Quality and Technical Supervision Bureau of each prefecture-level city, and is a special equipment statutory inspection and testing institution, which is led and supervised by the quality and technical supervision department.

It undertakes the quality supervision and inspection, regular inspection, installation quality supervision and inspection, repair and transformation of lead cars, import and export safety performance supervision and inspection, regular inspection of railway tank cars and automobile tank cars, accident inspection and analysis of boiler water quality treatment, regular inspection of railway tank cars and automobile tank cars, accident inspection and analysis of boiler water quality treatment.

1. The local special inspection institute has a long general cycle.

2. When the lead is defeated, there is a qualified third-party testing machine.

The safety valve to the local quality and technical supervision bureau at or above the municipal level.

Tested at the local quality supervision department. Because the pressure safety valve is generally used in boilers, air compressors and other equipment, and these equipment belong to special equipment, it is necessary to go to the quality supervision department for testing.

Difference Between Safety Valve and Pressure Gauge::

1. The working pressure of the safety valve is less than the design pressure of the pressure vessel, and when the pressure in the pressure vessel exceeds the maximum allowable working pressure, the pressure is jumped and relieved, so as to protect the safety of the pressure vessel. The pressure gauge simply displays the pressure value in the pressure vessel in real time.

2. The inspection cycle of the two is not the same, under normal circumstances, the inspection cycle of the safety valve is one year, and the inspection cycle of the pressure gauge is half a year.

Safety valves and pressure gauges need to be calibrated

The safety valve and pressure gauge belong to the safety valve accessories, the safety valve belongs to the pressure protection equipment, and the pressure gauge belongs to the measuring instrument, according to the national pressure vessel use standards and measurement law, must be forced to calibrate every year.

Safety Valve and Pressure Gauge Calibration Report:

Generally are the local special inspection institute and metrology institute, take Shenzhen as an example, the safety valve is the Shenzhen special equipment safety inspection research institute issued after the safety valve calibration report, the pressure gauge in the Shenzhen Institute of Metrology and Quality Inspection issued after the verification of the calendar, of course, you can also find Liren electromechanical to help you throughout the process, the qualifications are all leaky, quickly get the safety valve and pressure gauge calibration report. <>

Safety valves and pressure gauges are important devices used in industrial production to protect the safety of equipment and control pressure, and need to be regularly inspected and maintained to ensure their normal operation. Generally speaking, the detection of safety valves and pressure gauges can be carried out in the following places:1

Related testing institutions: Some professional third-party testing institutions or certification bodies, such as the National Quality Supervision and Inspection and Quarantine (AQSIQ) certification body, China Special Equipment Testing and Research Institute, etc., can test, certify and identify safety valves and pressure gauges. 2.

Manufacturers or sellers of safety valves and pressure gauges: Some manufacturers or sellers of safety valves and pressure gauges also provide inspection and maintenance services to ensure that the quality and performance of their products meet standards and specifications. 3.

Industrial Xianghui production enterprises: In the industrial production site, safety valves and pressure gauges are essential equipment, and enterprises can entrust professionals or testing institutions to test and maintain them to ensure the safety and reliability of the equipment. It should be noted that the testing of safety valves and pressure gauges should be carried out by professional institutions or personnel with corresponding qualifications and technical capabilities to ensure the accuracy and credibility of the test results.

When using safety valves and pressure gauges, the relevant usage specifications and operating requirements should also be followed to ensure the safety and reliability of the equipment.

Special Equipment Inspection and Testing Institute.

Special equipment inspection and testing institutes, some areas for special equipment supervision and inspection institutes, for the local municipal quality and technical supervision bureau internal institutions, for special equipment statutory inspection and testing institutions, led and supervised by the quality and technical supervision department. The inspection requirements for special equipment stipulate that before the operation of the equipment, do a good job in the inspection work before the operation, including:

Power supply collapse and smart voltage, each switch state, safety protection device and on-site operating environment, etc.

Maintenance of safety valves:

1. The safety valve should have a device to prevent the hammer from moving by itself and a guide frame to limit the lever from deviating, and the spring-type safety valve should have a device to lift the handle and prevent the adjustment screw from being twisted casually.

2. It should be installed vertically in the highest position of the pot merchant and the header. Between safety valves or headers, there shall be no outlet pipes and valves for taking steam.

3. The cross-sectional area of the connecting pipe between the safety valve and the boiler should not be less than the residual inlet cross-sectional area of the safety valve. If several safety valves are installed together on a short pipe directly connected to the pot barrel, the cross-sectional area of the short pipe should not be less than the exhaust area of all safety valves. <>

A safety valve is an important safety device used to protect equipment and piping systems, and needs to be regularly inspected and maintained to ensure that it is working properly. In China, the main state macro of the safety of the full valve is responsible for the following two departments:1

General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ): AQSIQ is the quality supervision, inspection and quarantine department of China, which is responsible for issuing safety valve production licenses, inspection and testing certificates, etc., and conducting quality supervision and inspection of safety valves. 2.

Special equipment inspection agency: The special equipment inspection agency is an institution established in accordance with the "Special Equipment Safety Law", which is mainly responsible for the inspection and supervision of various types of special equipment. Safety valves are a type of special equipment that needs to be inspected and identified regularly.

Therefore, if you need to carry out the inspection and maintenance of safety valves, you can consult your local special equipment inspection agency or AQSIQ related department for specific testing procedures and requirements.

Can you add, I don't quite understand it.

Safety valves must be tested at the valve testing facility.

The safety valve calibration information management platform of the Municipal Special Inspection Institute has been launched recently, which has realized the upgrading of the safety valve calibration from the traditional written declaration manual detection to the electronic process, so as to provide enterprises with more high-quality, efficient and accurate services.

It is reported that after the platform is launched, the safety valve testing station will give an exclusive nameplate to each new safety valve for inspection, and the relevant information can be automatically identified every time the nameplate is scanned. At the same time, the platform will automatically select the range channel that meets the specified range according to the safety valve calibration procedures in the safety valve inspection process, automatically determine the qualified range, automatically identify the qualified results, and ensure the accuracy of the calibration results through high-precision pressure sensors.

After the platform is launched, enterprises can log in to the platform through the mobile platform APP, fill in the relevant files of the safety valve, make an appointment for inspection service, and also fill in the acceptance information through the self-service machine in the station, self-service printing of test reports and other related businesses. ”

Offline calibration of safety valves:

Before the validity period of the safety valve, the user shall disassemble the safety valve by a person with equipment operation qualification when the equipment stops running and the working pressure of the medium is zero. <
