Description

Изобретение относитс  к области обработки металлов давлением, а имен но к соединени м с корпусом сосуда высокого давлени , работающим при высоких давлени х и температурах По основному авт.св. W488756 известно соединение, которое осуществл етс  с помощью болтов, имеющих в своей нижней части безрезьбовую головку с хвостовиком, выполненным,в виде, например, квадрата. Головка болта проходит через отверсти  в кры ке и корпусе и фиксируетс  в корпусе упорным вкладышем в виде вилки. Хвос товик входит в -квадратное гнездо кор пуса и фиксирует болт, преп тству  его развороту при навертывании и свертывании гайки 1. Однако в известном устройстве на свинчивание Гаек с болтов при демонтажных работах затрачиваетс  много времени и труда. Кроме того, после длительной эксплуатации соединени  возможны случаи заедани  в резьбовом соединении при свинчивании гайки с болта, при этом удаление гайки с болта производитс  путем ее срезки. Целью изобретени   вл етс  уменьшение времени на демонтаж соединени   путем исключени  операции .свин.чивани  гайки с болта. Цель достигаетс  тем, что устройство снабжено проставкой, установленной под , при этом проставка выполнена в виде разрезного кольца, охватываемого обечайкой. Кроме того, простаВка может быть выполйена в виде вилки. На фиг. 1 показано соединение; общий вид, разрез; на фиг. 2 - проставка в виде разрезного кольца, охватываемого обечайкой; на фиг. 3 - проставка в виде вилки. Соединение крышки 1 с корпусом 2 осуществл етс  с помощью болтов 3, имеющих в своей нижней части безрезьбовую головку 4 и хвостовик 5, выполненный в виде, например, квадрата. Беэрезьбова  головка болта проходит через отверсти  6 и 7 крышки и корпуса и фиксируетс -упорным вкладышем в виде вилки 8, устанавливаемым в паз 9 корпуса. Хвостовик входит в гнездо 10 кольца 11, где и фиксирует болт от проворота. На верхней резьбовой .части болта монтируетс  быстросъемный узел, состо щий из проставки 12, установленной между опорной шайбой 13 и сфериThe invention relates to the field of metal forming, and specifically to connections with the body of a high pressure vessel operating at high pressures and temperatures According to the main author. W488756 known connection, which is carried out with the help of bolts, having in its lower part a threaded head with a shank, made, for example, in the form of a square. The head of the bolt passes through the holes in the cover and housing and is fixed in the housing by means of a thrust liner in the form of a plug. The tailpiece enters the square socket of the core and fixes the bolt, preventing it from turning when tightening and rolling up the nut 1. However, in the known device for screwing the nuts from the bolts, disassembling takes a lot of time and labor. In addition, after prolonged use of the joint, cases of jamming in the threaded joint are possible when screwing the nut off the bolt, while removing the nut from the bolt by cutting it. The aim of the invention is to reduce the time to dismantle the joint by eliminating the operation of twisting the nut from the bolt. The goal is achieved in that the device is provided with a spacer installed under, the spacer being designed as a split ring covered by a shell. In addition, a simple plug can be used. FIG. 1 shows a compound; general view, section; in fig. 2 - spacer in the form of a split ring covered by a shell; in fig. 3 - spacer in the form of a fork. The cover 1 is connected to the housing 2 by means of bolts 3, having in their lower part a threadless head 4 and a shank 5, made in the form of, for example, a square. The bolt-free head of the bolt passes through the holes 6 and 7 of the cover and the housing and is fixed with an invisible liner in the form of a plug 8 installed in the groove 9 of the housing. The shank enters the nest 10 of the ring 11, where it fixes the bolt against rotation. A quick-detachable assembly consisting of a spacer 12 installed between the support washer 13 and the sphere is mounted on the upper threaded part of the bolt.
