Abstract

The invention can be used in devices for producing ultrahigh pressures. Compression chambers 2 - 6 are interconnected by shut-off valves with valves, mounted on a common stem 15 and overlapping seats. The saddles are fixed on the walls 1 through the bellows installed oppositely in the adjacent chambers. Chambers 2-6 can be heated from the collector 9 with coolant or cooled from the collector 10 with refrigerant through heat-conducting pistons 13, connected to the actuator 14. The shut-off valves through the rod 15 and the pistons 13 move under the action of a control system including temperature sensors DT) 17, 18, remote control (PU) 19, actuators (IO) 20, 21, piston position sensor (DPP) 22. At a signal from DT 17 or 18, PU 19 sends a command to IO 20, 21 and valves in odd and even chambers are respectively closed or opened, and the heat supply The moving pistons 13 move to heat or cool the chambers. At the extreme positions of the pistons 13, the DPP 22 de-energizes the IO 20, 21, all the valves are closed by the action of the bellows. Making the valves controllable provides gas through passage in the chambers and additional cooling of the gas leaving the heated chambers, which increases efficiency and speed. 2 Il.

Description

; The invention relates to compaction growth and can be used in devices for obtaining super-high pressures.

The purpose of the invention is to increase efficiency.

FIG. 1 shows a multistep thermocompressor; FIG. 2 shows a valve on an enlarged scale.

The multistage thermocompressor contains 1 compression chambers 2-6, successively located through common heat insulating walls Kiji 1, connected to each other by means of cut-off Hiiix valves, made in the form of saddles 7, fixed on heat insulating walls i and shut-off shutters 8, a device for heating and cooling squeezed gas in the form of located (| along the chambers 2-6 collectors

9 and 10 for heat carrier and coolant and channels 11 and 1-2 located therein, in which heat-conducting pistons 13 are installed, separating channels 11 and 12 into cavities by the number of chambers and connected to the drive mechanism 14. Thermocompressor is equipped with a rod 15, bellows 16 and the control system of the valves and the movement of the pistons, the valves 8 of the valves are fixed on the stem 15, and their seats are mounted on the stacks 1 of the chambers 2-6 through the bellows 16, n) and even the 16 bellows of the even and odd 2-6 are opposite. The piston control and piston moving system contains two bimetallic temperature sensors 17 and 18, a control panel 19, two actuators 20 and 21, and a piston position sensor 22, with sensors 17 and 18 located near the cooling and heating walls of the chamber. 2. The first stage, one of the executive bodies 20 is connected to the rod 15, the second executive body 21 and the sensor 22 to the drive mechanism 14, and the sensors 17 and 18, the executive bodies 20 and 21 and the sensor 22 are connected to the console 19 by electric drives 2.3, The console 19 receives power from the source nick 24 food.

Multistage thermocompressor works as follows.

The chamber 2 of the first stage is filled with cold gas, which leads to the cooling of the sensors 17 and 18. This closes the contacts of the sensor 17, which is far from the cooling wall. The signal from the sensor 17 through the wires 23 enters the console 19, which by this signal with the help of the power source 24 supplies a constant voltage of a certain number to the outputs of the executive bodies

20 and 21. At the same time, the executive body 20 opens the

0 odd valves, and the executive body 21 with the help of the actuator 14 sets the pistons 13 to a position that ensures heat exchange between odd cam-ceramics- 2, 4 and 6 and the heat transfer fluid in the manifold 9, as well as between. even chambers 3 and 5 and the refrigerant in the manifold 10. In this case, the cubic through heat insulating walls 1 does not occur. When the pistons 13 take

0 extreme position in chambers 11 and 12, sensor 22 enters the command into console 19 to de-energize the actuators 20 and 21. All valves 8 valves will block the seat 7 under the action of forces

gas in odd 2, 4 And 6 and cooling in even 3, 5 chambers. When gas in the first chamber 2 is heated to the entire depth of the chamber, the bimetallic plate of sensor 18 will be heated, which is far from the gas heating wall, which will give a signal to the console 19. The console 19 will receive a signal organs 20 and

21 is a constant voltage with polarity opposite to polarity for the case when the signal enters the console 19 from the sensor 17. The actuator 20 moves the rod 15. To the left. The closures of the 8 valves of the even chambers are opened. 3, 5, providing the flow of gas from the charge chambers 2, 4 and 6

in even 3, 5. This process is accompanied by an exhaust effect, which leads to additional cooling of the flowing part of the gas. At the same time, the actuator 21 uses the actuator 14 to move the pistons 13 to a position that provides heat exchange between the even chambers 3, 5 and the coolant in the manifold 9, as well as between the odd chambers 2, 4 and 6 and the refrigerant in the chamber 10. When the pistons, 13 will occupy the extreme position, the sensor 22 will issue a signal to the remote control 19, which will de-energize the executive bodies 20- and 21. The rod 15 will then be 5

The middle position ensures that all the saddles 7 are closed by the shutters 8. After cooling the odd 2, 4 and 6 and heating the even 3, 4 chambers, the control systems will move the pistons 13 to another extreme position. At the same time, a new portion of gas will enter the compressor. Upon filling all chambers with gas, the thermocompressor begins the process of its compression and delivery to the consumer. The execution of controllable channels provides isochorne heating of gas in the chambers and additional cooling of the gas leaving the heated chambers, which increases the efficiency and speed of the compressor.
