Изобретение относитс  к области арматуростроени  и предназначено дл  герметичного соединени  сильфонов из полимерных материалов и запорных органов, футерованных также полимерными материалами .The invention relates to the field of fittings and is intended for the hermetic joining of bellows made of polymeric materials and shut-off organs, lined also with polymeric materials.

Известна конструкпи  узла соединени  сильфон - запорный орган, в которой соединение осуществл етс  с помоидью резьбовой пары 1.The known construction of the connection unit bellows is a locking member, in which the connection is made with the help of the threaded pair 1.

Недостаток этой конструкции состоит в том, что, если полимерные материалы имеют пластическую деформацию, то соединение необходимо периодически подт гивать.The disadvantage of this design is that, if polymeric materials have plastic deformation, then the joint should be tightened periodically.

Известен также узел соединени  футерованного запорного органа с сильфоном, один конец которого поджат с помощью упругого элемента к футеровке запорного органа, выполненного с расточкой 2.A knot of joining a lined closure member with a bellows is also known, one end of which is pressed by means of an elastic element to the lining of the closure member formed with a bore 2.

В этой конструкции дл  компенсации ползучести и обеспечени  посто нной герметичности соединени  введен упругий элемент (пружина).In this construction, to compensate for creep and ensure constant tightness of the joint, an elastic element (spring) is inserted.

Недостатком указанного узла  вл ютс  сложность конструкции и недостаточна  надежность узла.The disadvantage of this node is the design complexity and lack of reliability of the node.

Целью изобретени   вл етс  упрощение конструкции и повышение ее надежности.The aim of the invention is to simplify the design and increase its reliability.

Указанна  цель достигаетс  тем, что конец сильфопа введен в расточку запорного This goal is achieved by the fact that the end of the sylfope is inserted into the boring

органа, а упругий элемент расположен между дном расточки и концом спльфона, поджатым к упругому элементу футеровочиым элементом.body, and the elastic element is located between the bottom of the bore and the end of the splfon, pressed against the elastic element lining element.

На чертеже нзображен предлагаемый узел соединени  футерованного запорного органа с сильфоном, продольный разрез (слева- - узел соединенп  до футеровани  запорного органа, справа - узел соединени  после футеровани  запорного органа).The drawing shows the proposed joint of the lining of the closure body with the bellows, a longitudinal section (on the left is the node connected to the lining of the closure body, on the right is the connection node after the lining of the closure body).

Узел соединени  состоит из запорного органа 1 с расточкой 2, сильфона 3, конец которого введен в расточку 2, упругого элемента 4, размещенного в расточке 2 между ее дном и концом сильфона 3 и поджатого футеровочным материалом 5, опорной шайбы 6, скрепленной с запорным органом 1.The joint assembly consists of a locking member 1 with a boring 2, a bellows 3, the end of which is inserted into the boring 2, an elastic element 4 placed in the boring 2 between its bottom and the end of the bellows 3 and preloaded with a lining material 5, a supporting washer 6 fastened to the locking organ one.

В процессе футерованп  запорного органа 1 расплав полимера под давлением входит в расточку 2, сжимает конец снльфонаIn the process lining the valve body 1, the polymer melt under pressure enters the bore 2, compresses the end of the snfone

3и контактнрующнй с ним упругпй элемент3 and an elastic element in contact with it

В результате этого между концом сильфона 3 и оиорной шайбой 6 образуетс  кольцева  прокладка, неразрывно св занна  футеровкой запорного органа 1 и наход ща с  под посто нным воздействием упругого элемента 4, который обеспечивает надежную герметизацию соединени  прн длительной эксплуатации узла, компенсиру  ползучесть материалов узла соединени  во времени.As a result, an annular gasket is formed between the end of the bellows 3 and the abutment washer 6, which is inextricably linked by the lining of the locking member 1 and under the constant influence of the elastic element 4, which ensures reliable sealing of the joint of the unit for long-term operation, compensating for of time.
