Description
(S) СПОСОБ ИСПЫТАНИЙ ПОЛЫХ ИЗДЕЛИЙ НА ПРОЧНОСТЬ ПРИ КРИОГЕННЫХ ТЕМПЕРАТУРАХ(S) TEST METHOD FOR EMPTY PRODUCTS FOR DURABILITY UNDER CRYOGENIC TEMPERATURES
Изобретение относитс к испытани м на прочность полых изделий, работающих под давлением при криогенных температурах. - This invention relates to testing the strength of hollow articles operating under pressure at cryogenic temperatures. -
Известен способ испытаний изделий на прочность, заключающийс в том, что в полость издели подают криогенную жидкость и создают необходимое давление жидкости 1.The known method of testing products for strength, which consists in supplying a cryogenic liquid into the product cavity and creating the necessary fluid pressure 1.

Недостатком известного способа вл етс высока стоимость испыта .НИИ, св занна с необходимостью сооружений защитных устройств, занимающих значительные производственные площади.The disadvantage of this method is the high cost of testing. The research institute is associated with the need to build protective devices that occupy large production areas.
Наиболее близким по технической . сущности и достигаемому результату к изобретению вл етс способ испытаний полых изделий на прочность при криогенных температурах, заключающийс в том, что изделие помещают в криостат и подают в изделие криогенную жидкость под давлением 2}.The closest technical. The essence and the achieved result of the invention is the method of testing hollow products for strength at cryogenic temperatures, which means that the product is placed in a cryostat and the cryogenic liquid is fed into the product under pressure 2}.
Недостатками известного способа вл ютс отличи условий испытани от натурных условий, обусловленное существенным теплопритоком к внешней поверхности издели и к подаваемой в него криогенной жидкости, а также недостаточна безопасность испытаний, св занна с большой энергией взрыва при разрушении издели .The disadvantages of this method are the differences in the test conditions from the natural conditions, due to the significant heat leakage to the external surface of the product and to the cryogenic liquid supplied to it, as well as the insufficient safety of the tests, associated with high explosion energy during the destruction of the product.
Цель изобретени - повышение безопасности испытаний и приближение их к натурным услови м. The purpose of the invention is to increase the safety of the tests and to bring them closer to natural conditions.
Эта цель достигаетс тем, что согласно способу испытаний полых изделий на прочность при криогенных температурах , заключающемус в том, что изделие помещают в криостат и подают в изделие криогенную жидкость под давлением, криогенную жидкость в процессе испытаний перепускают из издели в полость криостата с расходомThis goal is achieved by the fact that, according to the method of testing hollow articles for strength at cryogenic temperatures, which consists in placing the product in a cryostat and feeding a cryogenic liquid under pressure into the product, cryogenic liquid is transferred from the product to the cryostat cavity during the test.
