SU23653A1 - Instrument for recording pressure and flow time through the working agent pipeline - Google Patents

Description

The proposed device for recording and recording the pressure of steam, gas, etc. flowing through the pipeline is related to such devices of this purpose, which are equipped with a membrane that transmits pressure changes to the movable pin, and through it to a pencil or pen, which brings these changes into a continuous line. on the tape, fixed on the drum, driven by the movement of B clockwork. The device has devices for stopping, when the pressure drops below the established rate, the control hours and the clock mechanism driving the tape for recording, in order to determine and take into account the idle time of the device served by the device.

The device shown schematically in the drawing is mounted with its flange 13 on the flange branch 12 of the pipe 11. The membranes 14 are fixed between the two flanges, on which the rod 4 is supported, loaded with spring 5 and connected to the rod 16. The latter can act from one side through the lever system 19-21 on the needle 22, suspending when the pressure in the pipeline decreases, the progress of the control chassis 18, and on the other hand, with its knee 20 through the lever 15 on the needle 17, stopping the clock mechanism 2, rotating the pinion 7 through the gears 6 ntoy, which produced record. The drum makes a frustration at twenty-four and at the same

the time is lowered down its S axis by means of a protrusion 9 on it, which enters the groove 10 on the axis 8.

The subject matter of the invention.

1. An instrument to take into account the pressure and flow time of the working agent through the pipeline, equipped with a membrane that transmits a pin drive, which continuously indicates pressure on a tape mounted on a drum driven by a tape, characterized by the use of two needles 22 and 17 moved with a lever transmission 21, 20, 15 rod 16 ,. loaded with spring 5 and resting in the membrane, which is under pressure of agent flowing through the pipeline, from which needles needle 22: is intended to stop the control hours, and stop the clock mechanism of the recording device when the pressure drops below the established norm, to determine and take into account idling device equipped with the device.

2. Application of the tape-carrying drum 7 in the device specified in p. 1, which receives translational motion along its axis 8 using the groove 10 NNN and protrusion 9 on the drum, while rotating the last gear B from the clock mechanism.
