стей гидроцилиндров. Давление па выходе блока предотвращени  образовани  вакуума 7 настраиваетс  редукционным клапаном 9.Stey hydraulic cylinders. The pressure on the outlet of the vacuum prevention unit 7 is adjusted by the pressure reducing valve 9.

Предмет изобретени Subject invention

Устройство дл  прижима и подъема каландровых валов, включающее гидроцилиндры, редукционные и обратные клапапы, реверсивный золотник, блок предотвращени  образовани  вакуума в гидроцилиндрах с обрат Ыми клапанами и гидростанцию с напорной и сливной магистрал ми, о т ;i и ч а ю щ с с с   тем, что, с целью предотвращени  образоваии  вакуума независимо от соотношени  плоп .адей давлени  поршневой и штоковой полостей гидроцилиндров, блок предотвращени  образовани  вакуума снабжен редукционным клапаном, выход которого соединен со входами обратных клапанов, а вход - с напорпой магистралью гидростанции.A device for clamping and lifting calender shafts, including hydraulic cylinders, pressure reducing and check valves, reversing spool, a unit for preventing the formation of a vacuum in hydraulic cylinders with reverse valves and a hydraulic station with discharge and drain lines, i and h By the fact that, in order to prevent the formation of vacuum, regardless of the ratio of the flat pressure elements of the piston and rod cavities of the hydraulic cylinders, the vacuum prevention unit is equipped with a pressure reducing valve, the output of which is connected to the inlets atnyh valves and input - with naporpoy hydroelectric backbone.
