Description

one

The invention relates to mechanical engineering and can be used in the petrochemical industry, heat and water supply and sewage.

The aim of the invention is to increase the efficiency of the device by making it possible to match its parameters with the parameters of the previous and subsequent sections of the hydraulic circuit.

The drawing shows a damper pulsation.

The device comprises a cylindrical body 1 with an inlet 2 and an outlet 3 with nozzles, coaxially with which the pipeline 4 communicated with them is installed. The cavity of the body 1 is divided by throttling elements 5, made in the form of perforated partitions,

The inlet 2 and outlet 3 fittings are provided with tapered nozzles 6 which taper inwardly into the housing 1, which can move in the axial direction either along the thread 7 or by changing the thickness of the gaskets 8. and 3. The pipeline 4 communicates with the cavity of the housing 1 through the annular channels 10 formed between the outer surface of the conical nozzles 6 and the inner surface of the conical nozzles 9.

The device works as follows.

In the absence of pulsations, a rib medium (liquid or gas) enters the inlet fitting 2, horses 121b5 .42

The nozzle 6 is connected to the pipe 4 and is discharged through the outlet fitting 3 with a conical nozzle 6. The working medium can also move in the opposite direction. At the same time, the device does not provide a flow of significant hydraulic resistance,

In the event of a pulsation

10 pressure (flow rate) in the flow of the working medium, the static component of the flow rate passes through the pipeline 4. In this case, the dynamic (pulsating) component of the flow rate

15 for which the pipe 4 has a large induction resistance, branches into the cavity of the housing 1 through the channels 10 and interacts with them with the cavity of the housing 1 (capacitance 20 Hbw resistance) and perforated partitions 5, which are active hydraulic resistances.

Device setting for blanking

25 oscillations of the working dreadlocks, coming from both the previous and subsequent sections of the hydraulic circuit (not shown), are carried out by independently adjusting the passage area of the channels 10, i.e. by changing their hydraulic resistances. This setting is provided by shifting the conical nozzles 6 along the thread 7 of the fittings 2 and 3 or by changing the thickness of the gaskets 8 between the housing 1 and the fittings 2 or 3. The possibility of independent adjustment of the hydraulic resistance of the channels 10 ensures the device to work optimally.
