Abstract

Изобретение относитс к контрольно-измерительной технике и позвол ет повысить надежность герметизации. С плитой 2 св заны полый цилиндрический корпус (К) 1 и фланец (Ф) 4 через полую т гу 3. Радиальное уплотнение 5 установлено на торце фланца 4. В К 1 установлены клинь 6 и стержни из двух частей 7 и 8. Ближние к центру части 8 подпружинены и имеют закруглени , которыми могут взаимодействовать с клинь ми 6. Дальние от центра части 7 установлены в К 1 с зазором, заполненным упругим материалом. Между собой части 7 и 8 сопр жены по наклонным к оси К 1 поверхност м 9. Перемещают Ф 4 относительно К 1, сжима уплотнение 5. Перемещают клинь 6 и части 7 и 8 стержней в сторону испытываемой трубы, фиксиру заглушку. Через полую т гу 3 подают давление. Ф 4 дополнительно сжимает уплотнение 5 и упираетс в К 1, а последний сдвигает части 8 стержней по наклонным поверхност м 9 относительно частей 7, которые сильнее прижимаютс к трубе. 1 з.п. ф-лы, 3 ил.The invention relates to instrumentation engineering and makes it possible to increase the reliability of sealing. The plate 2 is connected with a hollow cylindrical body (K) 1 and a flange (F) 4 through a hollow tube 3. Radial seal 5 is installed on the end face of flange 4. In K 1, there is a wedge 6 and rods from two parts 7 and 8. Near to The center of the part 8 is spring-loaded and has roundings, which can interact with the wedges 6. The parts 7 that are far from the center are installed in K 1 with a gap filled with elastic material. Between themselves, parts 7 and 8 are mated along surfaces 9 inclined to the axis K 1. Move F 4 relative to K 1, compressing seal 5. Move wedge 6 and parts 7 and 8 of the rods to the side of the test tube, fixing the cap. Through the hollow tgu 3 serves pressure. Ф 4 additionally compresses seal 5 and rests on K 1, and the latter shifts parts 8 of the rods along inclined surfaces 9 relative to parts 7, which are more strongly pressed against the pipe. 1 hp f-ly, 3 ill.

Claims

Claim

1. A plug for hollow products such as pipes, containing a hollow cylindrical body, a flange connected to it, a radial seal mounted on the end of the flange, wedges installed in the body with the possibility of axial movement of the wedges and clamps in the form of radially spring-loaded rods with rounding at one end, installed in the housing with the ability to interact with rounded ends with wedges, characterized in that. in order to increase the reliability of sealing, the rods are made of two parts conjugated along surfaces inclined to the axis of the housing, the parts of the rods distant from the center are installed in the housing with gaps to move along the axis of the housing relative to the parts closest to the center.

2. The plug according to claim 1, characterized in that the gaps between the body and the parts of the rods distant from the center are filled with elastic material.
