HA-A1-type safety valve on-line detector characteristics and uses
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 conduct "annual inspection" and setting on the safety valve for more than one year, in line with the national regulatory requirements for safety valve at least once a year. When the safety valve is under normal pressure so-called "cold state" test, it can solve the following practical problems in the field: Maintenance start screening out no need to overhaul the safety valve, especially the large diameter high position valve to save costs and Duration; checkout set after the safety valve by the transport, installation and other aspects of the opening Force often changes, in this regard, feeding before re-tuning; safety valve in series with the burst plate testing; welding on-site setting after grinding; on a variety of heating, heating boiler in the open before the safety valve pressure Technical Features The design of this instrument has extensively absorbed the advantages of similar products from home and abroad to date and has undergone major reforms in combination with the on-site inspection experience and the various needs of users. The main features are as follows: 1. Using the principle of fine- Strictly in line 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 conditions need to be carefully examined when testing: more viscous medium containing solid particles mixed media. Deep, low temperature media. Note: The instrument can not be used for spring-loaded safety valve, such as liquefied gas vehicle safety valve.
