Description

A kind of rupture disk type approval test testboard

Technical field

The utility model relates to process industrial superpressure explosion protection technical field, specially a kind of rupture disk type approval test is surveyed Test stand.

Background technique

The technique with high temperature, high-pressure property is widely present as the process industrial of primary operational medium using fluid and powder Material and product.Process industrial equipment is band press operation under normal conditions, and is stored using pressure vessel or press Or production related process material.Once the fault of fluctuation or manual operation by external environment, process device are easy to out The security risk of existing over-pressure over-temperature；Even after pressure reaches the limit values, irreversible deformation damage occurs for equipment, seriously It will cause violent explosion.Therefore, the controllability under the safety and fortuitous event to guarantee production process.Industrially usually adopt Pressure in equipment can be limited to peace using the technology of releasing by the main means for taking overpressure relief to damage as prevention apparatus superpressure In gamut.In a variety of pressure relief devices, the advantages that rupture disk is big with pressure release area, high sensitivity, No leakage, it has also become The pressure relief device being most widely used.

In general, according to the difference of rupture disk mechanical structure, rupture disk is divided into: flat rupture disk, antiarch shape are quick-fried Fragmentation, three kinds of positive arch rupture disk.Most of rupture disk may not have an opportunity to act from being installed to scrap, and only occur After accident, just can be evaluated whether it reliable, just can confirm whether it prevents the generation of accident or expansion.

China proposes the type approval test method of oneself on the basis of correlative study, with GB567.4-2012 " rupture disk The 4th part of safety device: type approval test " and two regulations of TSGZF003-2011 " blasting piece device safety and technical supervision regulation " For standard, main experiment process includes: surface quality inspection, burst pressure tests, fatigue test, lets out in type approval test High-volume test, flow resistance coefficient test 5 parts, and wherein burst pressure tests and fatigue test are the weights in entire type approval test In weight, it can directly determine under the conditions of identical pressure loading rupture disk whether can triggered as normal work response (i.e. Explosion occurs).However there is no special test equipments to be tested accordingly for main production firm domestic at present, when new Product needs to carry out type approval test when determining working performance, can only purchase a set of equipment again and exclusively carry out test or outer It wraps to external professional test mechanism or manufacturer and carries out；Biggish sample can not be established during sampling observation by also resulting in product. Objectively directly contributing domestic leading firm, to developing, novel explosion flake products interest is low, and there are biggish for product quality for this Loophole in turn results in middle and lower reaches of the China in manufacture chain in passive security Protection Product, lacks competitiveness, for this purpose, I Propose a kind of rupture disk type approval test testboard.
