Abstract

Изобретение относитс  к испытательной технике и позволит повысить надежность работы стенда. Стенд содержит раму со штангами 1. на которых установлены подвижна  уплотнительна  головка 2 с приводом и неподвижна  уплотнительна  головка 4. соединенна  с силовыми гидроцилиндрами 5, штоки 7 которых размещены в отверсти х 8, выполненных в головке 4, и св заны со штангами 1. По оси стенда размещен дополнительный гидроцилиндр 9. шток 11 которого установлен в отверстии 12 головки 4, при этом поршнева  полость гидроцилиндра 9 и штоковые полости гидроцилиндров 5 св заны между собой и источником 16 давлени . При создании избыточного давлени  внутри трубы 15 осевые силы, действующие на уплотнительные головки 2, 4, воспринимаютс  штангами 1, которые раст гиваютс , поршни 6 перемещаютс , компенсиру  осевую деформацию штанг 1 и штоков 7, головки 2, 4 удерживаютс  в неподвижном состо нии, обеспечива  надежность уплотнени  трубы 15. 1 ил.The invention relates to test equipment and will improve the reliability of the stand. The stand comprises a frame with rods 1. on which a movable sealing head 2 with a drive is mounted and a stationary sealing head 4. is connected to power hydraulic cylinders 5, the rods 7 of which are located in the holes 8 made in the head 4 and are connected to the rods 1. By an additional hydraulic cylinder 9 is placed on the stand axis. A rod 11 of which is installed in the hole 12 of the head 4, while the piston cavity of the hydraulic cylinder 9 and the rod cavities of the hydraulic cylinders 5 are connected to each other and to the pressure source 16. When excessive pressure is created inside the pipe 15, the axial forces acting on the sealing heads 2, 4 are absorbed by the rods 1, which are stretched, the pistons 6 move, compensating for the axial deformation of the rods 1 and rods 7, the heads 2, 4 are kept stationary, providing reliable sealing of the pipe 15. 1 il.
