Description
Technical field
The present invention relates to functional test desk, be specifically related to safety interlock functional test desk for quick opening pressure vessel.
Technical background
At present, fast opening type pressure container for prevent because of fast-open door panel do not close fully with regard to boost or equipment in pressure do not have to discharge and fully just open the security incident that door closure causes, according to country's " safe technology of pressure vessel supervision rules " regulation of (being called for short " content regulation "), must on fast opening type pressure container, install and use safety interlock.Accomplish closure or openness fast opening type pressure container safely, be that safety interlock is when influencing quick operating valve closure or openness motion (locking or decontrol), force value in the pressure vessel must be very near zero, and just the operating pressure value of safety interlock device of fast opening type pressure container is between 0～0.03MPa.Such pressure limit, the existing pressure display device that uses can't have been realized differentiating and demonstration on the pressure vessel.China's safety interlock device of fast opening type pressure container does not so far have the standard of quantification, make with inspection body and also lack in this respect quantitative test equipment, cause the inspection of safety interlock device of fast opening type pressure container only be confined to the accumulation of experience and qualitatively method come the function of judgment means to realize.
Realize the safety interlock device of fast opening type pressure container examination and test of products, must adopt the method for minute-pressure test, in 0～0.1MPa scope, the operating pressure value of safety interlock device of fast opening type pressure container measured and take this function of interlocking device is judged.Fast opening type pressure container uses extensively, and structure is various, the pattern difference, and switch is frequent, and the therefore stability test that must repeat continuously safety interlock device of fast opening type pressure container is to guarantee safety interlock reliably working in a round of visits.
According to State General Administration for Quality Supervision's plan of science and technology project " pressure vessel is studied with the type approval test of fast beginning lid and interlocking device " requirement, set up under the laboratory condition or batch production interlocking device functional test platform when producing, the accurate force value during test interlocking device closure or openness and it is carried out stability test, be able to the function of interlocking device is studied judgement, thereby change the present situation that China's safety interlock device of fast opening type pressure container lacks the type approval test pick-up unit, seemed very necessary.
