Small Safety Valve Portable Offline Testing Equipment Development

Safety valve on the boiler, pressure vessels, pressure piping and other special equipment has a very wide range of applications, to protect the safe operation of special equipment related important accessory. Safety valve in the course, affected the working pressure, temperature, medium, and its performance will change the action, resulting in not working properly, causing the leak, overpressure operation and other threats to production safety accidents. To this end, china has proposed the need for regular check valve mandatory requirement.In this paper, on the basis of the traditional off-line check valve, both portability for small valve, safety valve intelligent offline calibration equipment to conduct research. By measuring system optimization design, structural strength finite element analysis, development, equipment performance testing applications work checksum management of intelligent systems, developed a safety valve can be directly applied to the site off-line check valve small smart offline calibration equipment, specific findings are as follows:(1) Fully consider the safety valve function offline calibration equipment, mechanical strength and operational reliability of the equipment, key components of the finite element structural optimization, to achieve a lightweight design. Compared with the current mainstream car portable safety valve calibration equipment, the total weight of the entire device significantly reduced, improving the portability of calibration equipment.(2) High-precision sensors and microcontrollers combine built-in data acquisition systems and real-time data processing software verification, calibration equipment reduces the traditional human intervention accidental error and improve the measurement accuracy of the calibration data and the verification process can be traced back sex.(3) Touch screen as the user interface to improve ease of equipment operation; data management system using the valve with a background software support, to achieve safety valve verification process commission accepted, archiving, validation, issue a report and so the whole process automation and electronics technology.(4) Calibration device connector using an open architecture design for spring DN15-DN50, flanged and special off-line check valve sealing surface; pipeline equipment package, according to 6.0Mpa pressure valve design, the highest You can check the safety valve nominal pressure 4.0Mpa.
