Description

one

The invention relates to a hydraulic pressure transducer used in land reclamation, as well as in a water supply system for raising water from gravity flow pipelines to a higher level than their water intakes.

Hydraulic pressure transducers for pulsating water supply are known, consisting of a housing, supply, pressure and discharge lines and a device for creating an overpressure in front of the pressure line valve. However, these converters are not adapted for high water consumption, have a low efficiency, which decreases depending on the lifting height and, moreover, a hydraulic shock is created during the operation of such converters, which is why it is necessary to lay steel pipes.

To increase operational reliability and increase efficiency in the proposed converter, the device for creating overpressure is made in the form of a stepped piston, to the inner side of which is attached a rod with a lancet end, scented with a spring-loaded rod, equipped with a lever that interacts with the overlapping flush piping pipe , and with an emphasis, acting as a dropper

the rod in the upper position of the piston to shut off the feed pipe, and the piston cavity communicates with the feed pipe through the additional pipe with a check valve. To rotate the rod with a lever for engaging it with a thrust and valve, the spring of the rod is attached at one end to the base of the body and the other to the rod.

On fpg. 1 shows the converter at the time of the start of the operation; in fig. 2 is the same at the time of the end of the work cycle.

The hydraulic pressure transducer includes a housing /, which is connected to the pressure pipe 2 by a check valve 3. 1

The upper part of the housing is fastened with a connector pipe 4 with a check valve 5 located on the supply pipe 6. Inside the housing there is a piston 7 of variable cross section. In the upper, broadened part of the body, holes are worn for solenoid atmospheric pressure. A piston 7 is rigidly attached to the piston 7 from the inside with a tide for engaging the lever 9 rigidly attached to the rod 10 with a spring //

J2 valve. The lever 9 in the working position rests on the tide / 5 of the flap 14. A thrust bracket is mounted on the exhaust pipe 15). The pressure transmitter operates as follows. Water enters the pipeline 6, then through the connecting pipe 4 enters the piston chamber and through the check valve into the pressure pipe 2. Under pressure of water, the piston 7, moving, as 8, moves the lever 9 towards the side, releasing the tide 13 of the valve 14. At the same time ha 8 enters into zappel with its tide with lever 9 and the released valve 14 turns around the axis under the pressure of water and closes the outlet pipe 15. Water entering through the supply pipe 6 fills the sub-piston space, creating pressure, which causes 7, moves up and moves the water column in the pressure pipe. The check valve 5 closes, mt 8, move together with the piston 7 and move in engagement with the lever 9, the shaft 10, lifts it, compressing the valve spring 11 11. Raise the lever until it stops at the support bracket 16 and turns pulled down by the influx of 8, and under the action of a compressed spring // presses the tide 13 of the flap M, which, turning, opens the passage of water into the exhaust pipe 15, at the same time blocking the inlet of the feed pipe 6. The piston cavity is relieved of water, the pressure under piston 7 falls, the piston moves downward. The valve 5 closes, the valve 5 opens. The pressure of water on the upper part of the shaft 7 accelerates its displacement, the thrust of the ha 8, the slip along the lever 9, engages in it with its tide. The lever 9 with the brush 10 rotates, overcoming the elasticity of the spring 11. With further movement of the piston 7 with a tightness of 8, the latter moves the lever 9 with the tide 13 of the valve 14, and the cycle repeats. The subject of the invention 1. A hydraulic pressure transducer for pulsating water supply, including a housing, supply, discharge and discharge lines, a device for creating an overpressure in front of the pressure line valve, characterized in that, in order to increase operational reliability and increase the efficiency, the device to create an overpressure made in the form of a stepped piston, to the inner side of which a rod is attached with a pointed end that engages with the springs nnym rod provided with a lever cooperating with the overlapping feed of n drain pipes flap, and with an abutment which acts as a diverter rod in the upper position of the piston for closing the supply conduit and subpiston chamber communicates with the supply line via a further line with a check valve. 2. A transducer according to claim 1, characterized in that, in order to rotate the stem with the lever and engage it with the thrust and the flap, the stem spring is attached at one end to the base of the housing, and the other to the stem.
