Description

Устройство включает цилиндр 1, поршень 2, шток 3, В полости штока помещаетс  рейка 4, св занна  с хомутом 5. На верхней части рейки имеютс  зубь  дл  зацеплени  ее с храповым механизмом б. Полость Б цилиндра 1 соединена трубкой 7 с обратным клапаном 8, а полость В цилиндра 1 трубкой 9 с обратньзм клапаном 10 входные патрубки обратных клапанов 8 и 10 св заны с трубкой 11 с емкостью 12 дл  хранени  ингибитора коррозии, а выходные патрубки тех же клапанов трубкой 13 с желобом 14 и трубкой 15 - с желобом 16, The device includes a cylinder 1, a piston 2, a rod 3. In the stem cavity there is a rail 4 connected to the collar 5. On the upper part of the rail there are teeth for engaging it with the ratchet mechanism b. The cavity B of cylinder 1 is connected by tube 7 with a check valve 8, and cavity B of cylinder 1 by tube 9 with inverse valve 10, the inlets of check valves 8 and 10 are connected to tube 11 with a capacity of 12 for storing the corrosion inhibitor, and the outlets of the same valves by tube 13 with a chute 14 and a tube 15 - with a chute 16,

Хомут 5 крепитс  на трубопроводе 17, Последний свободно лежит .на опоре 18, на которой жестко закреплён цилиндр. Опора снабжена узлом смазывани , состо щим из сальников 19 и 20, плотно прижатых к нижней части трубопровода 17.The collar 5 is fastened on the pipeline 17, the latter freely lying on the support 18 on which the cylinder is rigidly fixed. The support is provided with a lubrication unit consisting of glands 19 and 20, tightly pressed against the lower part of the pipeline 17.

Устройство работает следующим образом The device works as follows

При изменени х длины трубопровода 17 вследствие температурных деформаций происходит его перемещение относительно опоры 18, Хомут 5, Перемеща сь вместе с трубопроводом 17, приводит в движение рейку 4.When the length of the pipeline 17 changes due to temperature deformations, it moves relative to the support 18, the clamp 5, Moving along with the pipeline 17, drives the rail 4.

Усилие от рейки 4 через храповый механизм 6 передаетс  на шток 3, перемеща  его вместе с поршнем 2.The force from the rail 4 is transmitted through the ratchet mechanism 6 to the rod 3, moving it along with the piston 2.

При больитх температурных деформаци х трубопровода 17, когда длина перемещени  хомута 5 относительно .опоры 18 превышает длину рабочего хода поршн  2, срабатывает храповой механизм 6, предохран   устройство от поломки.With large temperature deformations of the pipe 17, when the length of movement of the collar 5 relative to the support 18 exceeds the length of the working stroke of the piston 2, the ratchet mechanism 6 is activated, protecting the device from breakage.

При движении поршн  2 влево ингибитор коррозии из емкости 12 по трубке 11 через обратный клапан 8 по трубке 7 всасываетс  в Полость Б цилиндра 1. Одновременно из полости В цилиндра 1 ингибитор коррозии по трубке 9 через обратный клапан 10When the piston 2 moves to the left, the corrosion inhibitor from the tank 12 through the tube 11 through the check valve 8 through the tube 7 is sucked into the cavity B of the cylinder 1. At the same time, from the cavity B of the cylinder 1 the corrosion inhibitor through the tube 9 through the check valve 10

по трубкам 13 и 15 поступает в желоб 14 и желоб 16.pipes 13 and 15 enters the chute 14 and the chute 16.

При движении поршн  2 вправо ингибитор коррозии из емкости 12 по трубке 11 через обратный клапан 10 по f трубке 9 всасываетс  в полость В цилиндра 1.When the piston 2 moves to the right, the corrosion inhibitor from the tank 12 through the tube 11 through the check valve 10 through the tube 9 is sucked into the cavity B of the cylinder 1.

Одновременно из полости Б цилиндра 1 ингибитор корроз.ии по трубке 7 через обратный клапан 8 по трубкамAt the same time, from the cavity B of cylinder 1, a corrosion inhibitor in tube 7 through a check valve 8 in tubes

13 и 15 поступает в желобы 14 и 16.13 and 15 enters channels 14 and 16.

Из них ингибитор коррозии стекает на, поверхность трубопровода 17, соприкасающуюс  с опорой 18.Of these, the corrosion inhibitor flows onto the surface of the pipeline 17 in contact with the support 18.

Поступающий ингибитор коррозии равномерно смазывает сальниками 5 19 и 20 поверхность трубопровода 17 при его перемещении относительно опоры 18,The incoming corrosion inhibitor evenly lubricates the glands 5 19 and 20 of the surface of the pipeline 17 when it moves relative to the support 18,
