SU10179A1 - Device for automatically controlling the actions of devices, in particular, fireboxes - Google Patents

Description

Devices are known for automatically controlling the operation of devices, in particular, fireboxes, using small shifting forces and with switching-on between the device that causes the regulation and the device that performs the regulation, the amplifier. In the proposed device, said reinforcement consists of two bars, mounted on guides and. under the influence of three springs, one of which is connected with the regulating authority. Between the bars, it is freely moved by the action of the device causing the adjustment, which, when clamped between the bars, transfers movement from one bar to another. The clamp, the meter of which is determined by the position of the stone and the bevel of the surface of one of the bars, is carried out under the influence of a fist-rod, receiving reciprocating displacements from sama, m:

piston mechanism. In order to stop one of the bars in positions independent of the position of the other beam, a lever system is used that is driven by the same fist-piece. The aim is to increase the sensitivity of the device using a device for moving stones, which operates according to the same principle as the device described.

The device is mainly used for automatic control of the operation of boilers, whereby thermocouples, carbon dioxide meters, pressure gauges and other similar devices that serve as observers are used as transmitting organs. This is due to the condition of the Bi vapor of a certain part of the SylowX installation. The force that causes the regulatory process does not depend on the permutation force that causes the beginning of the regulatory process, as a result of which the latter can be extremely small, while the former can be chosen

(liHHj so that the friction of rest and motion resistance does not affect the regulatory process at all.

In FIG. 1 schematically depicts the proposed device; FIG. 2 - drive to the fist rail; FIG. 3 - a device for moving stones; FIG. 4 is a diagram showing the relationship between movements of parts of the device.

The beginning of the regulatory process is carried out by stones I, driven by some device causing regulation, for example, from the needle of the manometer, in the directions indicated by arrows in the drawing. Changes in the position of the stone 1 should be transmitted to the regulating authority 2. For this purpose, two movable bars 3 and 4 are provided, moving on guide posts 5 and 6 and under the influence of springs 7, 8 and 9 (Fig. 1). A pulley I is attached to beam 3, along which a rake rail 12 guided by roller 45 moves, driven by an engine 13 (Fig. 2). The latter, by means of a gear train 14, drives the pump 15, the cylinder of which communicates with the working cylinder 16. Moving, in the latter, the piston 17 is connected to the fist rail 12. During the return stroke of the pump 15, the spring 18 returns the piston 17, into its left dead position.

The beam 4, by means of the piston rod 19, the cylindrical membrane 20 and the pipeline 21, is connected to the cylindrical membrane 22 to which the regulating body 2 is attached. The cylindrical membranes 20 and 22 and the pipeline 21 are filled with liquid (for example, oil) and represent a hydraulic transmission .

The regulatory process proceeds as follows: under the action of the stone i, which moves the forces

moves from the position it is in at the moment. The piston 16 moves the cam rail 12 to the right, at which with its last swaged surface 23, by means of the roller 11, shuffles, the bar 3 down. A stone, 1, is also involved in this vertical downward movement, which at the same time goes into bar-4 and moves it down until the lower edge 24 of the rail 12 runs onto roller 11. At this moment the movement of bar 3, and with it beam 4 is terminated. The beam 4, and with it the regulator 2, came to a position corresponding to the position of the transmitting organ (force. The stroke of beam 4 varies, thus, depending on the excess of the bevel of its surface 25 in the place where stone 1 comes with it The movement of timber 4 more or less depends on the cylindrical membrane 20, i.e. more oil is pressed into the cylindrical membrane 22, and the movement of regulator 2 moves up or down by the required amount.

Another part is attached to the described device, namely the lever system 28, 30, .26, designed to hold the beam 4, and with the bottom and the organ 2, in the position caused by the position of the stone 1 and the surface 24, and for stopping the beam 4, during the return stroke of the rail 12. The second task of the said system is to allow the reverse movement of the timber 4 under the action of the spring 9 only from the moment when stone 1 takes its corresponding regulating position during the next adjustment cycle. In case stone 1 is a regulating impulse. installed in the new position, to the left of the previous position, the bar 4 must be moved with

spring e. If the stone and stone 1 moves to the right, then it will immediately move the beam 4 immediately, as t (: just touch it. Lever and the system works as follows. During the front line: rail 12 to the right set lever 26

; is released by means of the stop 27 and the lever 28. For this purpose between the levers 26 and 23. There may be provided a lock on the 30th coupling and another eO-appropriate tool. Petea 12 moves to the right until ular 27 depresses lever 28, contrary to the action of spring 29, to the right so that clamping device 80 is released. This lever can move freely and during the course of beam 4 moves downward under the action of the load 7, and during its upward movement - under the influence of the spring 9. When the strip 12 begins again to move to the left, the stop 27 releases the lever 28, with the latter throwing over to the left, secures the setting lever 26 and dtih blocks the path to further movement of the beam 4. The described device for adjustment can be applied at the lowest moving forces; by switching on an additional device for moving the stone 1.y; - /.

This additional device operates in the same way as the main device described. Instead, provided for in Germany. 1 of the rail 12, there is an eccentric 31 acting on the rolling pin 321. The plate 33 is attached to the latter, and 34 is pressed against it. With its other end, the squad 34 rests on the lumber ZY moving along the guide posts 36 and 37. In addition, the device is equipped with a fixed beam 38i along which the stone slides 39.1 st, shown with an arrow of a galvanometer, etc. The surface 40 of the beam 35 is not parallel to the surface of the bar 38 ,. and has a lift to the right. When the eccentric 31 is in motion, the rolling pin 32 is pressed down and by means of the spring 34, the bar 85 moves downwards until it hits the gum 39. Upon further rotation of the eccentric -31, the spring 34 compresses, and the bar 85 cannot move further. . The movement of the timber Zb, through the adjusting screw41, is transmitted to the stone-1 through the transmission levers 42, 43. The screw 41 is equipped with a handwheel 44, allowing the ratio between the movement of the beam 35 and the stone 1 to be set. The force for resetting; stone I is centered on eccentric,: 31 through clip 32, plate 33, spring ii, beam 35, screw 41 and transmission levers 42 43, in addition to stone 39, which means that in the system can be adjusted in such a way that stone 39 comes to perceive a completely insignificant ocra toyus force and that, in accordance with this, it can be constructed as easily as possible:

In the diagram in FIG. : 4 are presented; the relationship between movements in the accessory and the main device. The whole circle corresponds to the complete adjustment cycle. Line 100 denotes the drive path of the additional instrument, and line 101 is the drive path of the main device. The same diagram also depicts the drive eccentrics for the additional instrument and the main device in the case when the cam bar 12 of FIG. 1 is replaced by an eccentric. Then the area shaded vertically is the elevation on the eccentric of the additional instrument, and the area shaded horizontally is the same for the main device. At point A, the beam of the beam 35 begins, the endpoint (; its at point B. Eorus 85 maintains its position to the point G, and, from here begins his movement, his movement, Zach; aichivayphees in N. From R to stone 89 can freely be installed. During the movement of the extrasiurik 31, the eccentric

nl from the C to free a stone | and ends that liberation; for D,, From D to E, the stone 1 mo “y Schch is brought into position, respectively; corresponding to the position of the beam 35, and at the same time in the proposed regulatory position. ; At E, the main timber begins to close the stone i, and ends this movement at F. If stone 1 is to the right of that position, | which he occupied in the previous adjustment cycle, then i beam 4 falls into the corresponding. momentum position immediately | contact with the stone, but if it is to the left, then the bar 4 is not; can be moved. In this case, it takes the position required for the adjustment process only after under the influence of spring 9, the brake between (7-H is unfolded. At 4, the brake is compressed again, and at the same time a new beam 35 begins. At C The second stage is locked in, and beam 4 is delayed accordingly, until after installation of stone 1, the main beam starts at E of the process of releasing the latter. With further movement of the stone to the left, as a result of movement of the stone 39 to the right, installation 1 can occur then when bars 3 and 4 are free D it. While it is clamped, the bar 35 cannot take a regulating position corresponding to the impulse, and therefore only 34 will be compressed. The correct position is obtained only under the influence of the expanding spring 34 and the resulting 35 in the correct position. In addition, as stone 1 is released from the pressure of the main bars 3 and 4, i.e., at point D of the diagram, the device can also be such that bar 35 and stone 1 move simultaneously.

In the foregoing, it was assumed that the timber of the main device should be driven by an additional device. If a

Since the forces (which must be overcome in the control mechanisms) are insignificant, it is possible to refuse the additional instrument and activate the control mechanisms directly from the beam of the main unit.
