Function and Application HA-A1-type safety valve on-line detector is a portable pressure relief valve for boilers in the field of a variety of spring-loaded safety valve, relief valve open pressure detection portable instrument. It can measure the safety valve Of the opening pressure without the need to increase the system pressure.It can be on-line safety valve in the operation of the problems arising from the on-line emergency response.Such as opening pressure failure of the safety valve on-line re-set on the back seat still leak The safety valve is effectively closed without changing its setting pressure.It can carry out "annual inspection" and setting on-line for safety valves operating for more than one year, in order to meet the national regulatory requirements for safety valves at least once a year. When the safety valve at atmospheric pressure under the so-called "cold state" test, it can solve the following practical problems in the field: ▲ overhaul began to stop screening out the need for overhaul of the safety valve, especially large-diameter high-position valve to save costs And duration; ▲ calibration station after setting the safety valve by the transport, installation and other aspects of the opening pressure often Health changes, in this regard, feeding before re-tuning; ▲ Detection of safety valves in series with the blasting plate; ▲ On-site setting of the welding valve after grinding; ▲ For all heating, heating boiler safety valve Pressure Technical Features The instrument design has extensively absorbed the advantages of similar products so far, combined with many years of field experience and user needs a major reform, the main features are as follows: 1. , In strict accordance with international standards. 2. Detection is the valve does not jump, does not disturb the production conditions. 3. Novel screw-type chuck to ensure that the mechanical bracket can be securely fixed on the safety valve, adjustable chuck to adapt to a variety of different sizes stem. 4. Safe and reliable limit mechanism, limit the opening height, do not disturb the production conditions. 5. After the seat back to the leak can be used to force the closure of the valve will be forced to close. High pressure and high pressure safety valve can be specially designed by our company light hydraulic system, without affecting the value of fixed pressure. 6 hydraulic external force system, Canadian force smooth, suitable for large external force occasions, external force curve is gentle, stable. 7. High-sensitivity audio monitoring technology. 8. Can be online hot, cold check safety valve opening pressure. 9. Threaded stems can be used with special coupling clamping system. 10. Using high precision A / D reference power module, to ensure the measurement accuracy. Easy to install, easy to operate. Scope 1, the detection process does not touch the working medium, therefore, the use of the instrument in theory and the detection of safety valve working medium type and medium pressure, temperature has nothing to do. 2, for a variety of models, the size of the spring-loaded safety valve, pressure relief valve testing. 3, the following situations need to be carefully handled when testing: 1) more viscous medium 2) containing solid particles mixed media. 3) deep low temperature medium. Note: The instrument can not be used for spring-loaded safety valve, such as liquefied gas vehicle safety valve.
