Established in 2016, Shandong Haoguyi Electromechanical Equipment Co., Ltd. is a professional company that produces, assembles and sells safety valve online calibrators with independent research and development capabilities.

Safety valve online verification belongs to a new technology in recent years, and is mainly applied to the opening pressure test of various spring direct load type safety valves of various boilers and pressure vessel equipment. Since the on-line measuring safety valve opening pressure, the production device does not need to require the equipment to stop operation, and the enterprise production can operate normally. Therefore, after the successful application of online verification technology, it has aroused great interest from the industry, especially the modern process industry, and is widely used in the chemical and power industries. Relevant data show that the promotion and application of the safety valve online verification technology effectively deal with the problems that have always existed in the actual operation process, such as online constant pressure on the off-site, which can greatly promote the long-term cycle of the overall production operation. Stability, the realization of the safety valve without disassembly directly online verification, reducing the verification cost, is a supplement to the offline verification of the safety valve, the promotion of this technology can obtain good economic and social benefits.
