Изобретение относитс к криогенной технике и может найти применение в химическом и нефт ном машиностроении и газовой промышленности при работе на продуктах, имеющих температуру ниже .The invention relates to cryogenic engineering and can be used in the chemical and petroleum engineering and gas industries when working on products having a lower temperature.

Известно запорное устройство дл работы на криогенных средах, состо щее из кожуха и соосно расположенного в нем корпуса, установленного под углом к потоку среды и центрированного относительно кожуха подвижными и неподвижными опорами и выполненными из изол ционного материала стержн ми и т гами, причем в корпусе расположен запорный орган, св занный с штоком привода 1.A locking device for operation on cryogenic media is known, consisting of a casing and a housing coaxially disposed therein, mounted at an angle to the flow of the medium and movable and stationary supports centered with respect to the casing and made of insulating material with rods and rods shut-off element associated with the actuator stem 1.

Известное устройство имеет недостатки: при приваривании неподвижной опоры к кожуху происходит перекос т г, нарушаетс соосность и создаютс дополнительные деформируюшие усили на т гу, работающую в такой конструкции на раст жение и сжатие. В насто щее вроис The known device has drawbacks: when welding a stationary support to the casing, a distortion of g is occurring, the coaxiality is disturbed and additional deforming forces are applied to the grommet, working in such a structure for tension and compression. Nowadays

повышены требовани к конструкци м криогенной арматуры в той части, что осевые и радиальные усили от трубопроводов , возникающие в результате температурных деформаций и давлени среды замыкаютс на арматуре. Из анализа конструкции на прочность установлено, что возможен выход из стро т г в местах креплени их к опорам.increased requirements for cryogenic reinforcement structures in that part, that axial and radial forces from pipelines resulting from temperature distortions and medium pressure are closed at the reinforcement. From the analysis of the structure for strength, it was established that it is possible to fail at the points of their attachment to the supports.

Цель изобретени - повьпиение надежности устройства.The purpose of the invention is to increase the reliability of the device.

Claims

The goal is achieved by the fact that the fixed supports are made on both sides of the movable support, sockets are provided in the supports, the fixed supports are provided with threaded holes with screws fixed in them, and the rods are made in the form of dual rods installed in the supports sockets can be adjusted with screws of fixed supports, the rods being provided with metal caps with spherical outer surfaces. 381 FIG. I shows the locking device section j in FIG. 2 cut. A-A in FIG. I. The locking device consists of a stem 1 installed tightly in the housing 2, the actuator 3, the locking member 4, the rods 5 of insulating material, the casing 6. The device works in the following way. By supplying the control pressure, the valve 3 opens and closes alternately in the opening and closing cavities of the pneumatic cylinder of the actuator 3. As a result, the cryogenic medium produces temperature deformation, and the body 2 with the branch pipes connected to it perceives axial and radial loads from the main pipeline that exceeding the permissible loads leads to the destruction of the device, To the case 2, the cryogenic valve is welded to the movable support 7, and two fixed supports 8 are attached to COAUH 6. Sculpted in the form of rods 9 dual and made of fiberglass. On the ends of the rods 9, the centering caps 10 are mounted metal with spherical outer surfaces B. The rods 9 with the caps Yu are placed with the end in the slots C of the movable support 7, and the other end in the slots C of the fixed supports 8 located on both sides of the independently movable support 7. In the fixed supports there are threaded holes D, in which screws II are installed. When screwing in screw 11, cap Yu with a spherical surface is centered in the blind hole D of screw II, i.e. The rods 9 are centered. The screws 11 tighten the rods 9 until a rigid connection is formed between the movable support 7 and the fixed supports 8. Ta7 and the design of the rods expands the range of axial loads perceived by the body of the boom body, as the rod 9 operates and only compression, which is the best option in comparison with constructive wounds, where similar devices work both on stretching and squeezing. The formula of the invention is 1. A locking device for operating npe-t on cryogenic media, consisting of a casing and a housing located in it, mounted under an angle to the flow of the medium, which are centrifuged relative to the casing by movable supports supported on the casing. and fixed supports fixed to the casing and made of insulating material by rods and rods, the pier in the hull has a locking member connected to the drive rod, which is aided by the fact that the fixed supports are located along both sides of the movable support, sockets are made in the supports, in the fixed supports of the threader are holes with screws installed in them, and the rods are made in the form of twin rods installed in the sockets of the supports with their fixed screws.

2. The device is populated with the fact that the rod is equipped with metal caps with spherical external surfaces. Sources of information taken into account in the examination. I. USSR Copyright Certificate No. 40499O, cl. F 16 K 49 / GS, 1972.
