Problems solved by technology

[0003] Refrigeration system safety valves are usually installed on containers and pipelines through short pipes. Off-line calibration needs to empty or transfer the refrigerant inside the refrigeration system, which brings a lot of manpower and material resources, and also pollutes the environment.

Abstract

The invention discloses an installable built-in device for online calibration of a safety valve for a refrigeration system and a using method. According to the built-in safety valve online calibrationdevice composed of an electric oil pump, a flow regulating valve, a hydraulic oil pipe, a quick connector, an oil cylinder, an oil cylinder support, a locking nut, a supporting column, a pressing rodbase, a positioning pin, a safety valve body, a positioning structure, a connecting piece, a pressing rod, a sensor, a sensor line, a data acquisition terminal and the like, the problem that an existing safety valve for a refrigeration system is inconvenient to calibrate off line is solved, and meanwhile, manpower and material resource consumption and environmental pollution are reduced.

Description

Technical field[0001]The invention relates to the technical field of safety valve detection, in particular to an on-line verification device for an installable built-in safety valve and a use method.Background technique[0002]The opening and closing parts of the safety valve are normally closed under normal working conditions. When the medium pressure in the equipment or pipeline exceeds its specified value, the opening and closing parts open to discharge the medium to the outside of the system to protect the special valve of the pipeline or equipment. Safety valves belong to the category of automatic valves, which are mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value and plays an important role in protecting personal safety and equipment operation. Safety valves must be pressure tested regularly before they can be used.[0003]Refrigeration system safety valves are usually installed on containers and pipes through short pi...
