(54) ELECTROMECHANICAL DEVICE

FOR REMOVAL OF GAS PILLOWS IN PIPELINES

agnita koryati 9 kbtergo kinematically into the shed with valve 1O valve 11. Return spring 12 connects B ;; ianajfi with takan 13, mounted on a pipe in a pipeline 14. All construction is fastened to rack 15;

The device works as follows. -

If there is no gas flow in the pipeline, the tipocfpaftcTBo and the Mining stations are filled with oil I, which ensures the self-excitation of the asynchronous generator 2 driven by the Micromotor 3. The process of self-excitation lasts a fraction of a second. The voltage of the generator through the Straightening unit 4 is applied to the relay coil b. The relay triggers and opens the contacts in the winding circuit of the 6 electromagnet, removing the voltage from it. At BTO, the return spring 12 holds the valve U in the closed position. Since the diblock gas permeability is 2.1–2.5 times lower than the differential permeability of oil, the gaa between pastinas has a capacitance capacitance sharply, which leads to a breakdown of self-excitation of the asynchronous generator while the voltage on the relay winding 4katc his contact 5 in the winding circuit of the electromagnet b, connecting it to the supply network. As a result, fmb vktromaGnita Prit no korv ..

After removing the gas cushion (plug) and filling the space between the plates of capacitors 1 with oil, self-excitation of the micro-oscillator 2 again occurs. Relay 5 triggers, the contact in the power supply circuit of the coil of the electromagnet opens and the valve 10 closes.

F o rm llu and zobretevi.

An electromechanical device for removing gas cushions in pipelines during transportation of an oil and gas mixture, comprising a gas-liquid mixture phase sensor and a valve with a valve, about V l and h; Since, in order to increase speed and ensure reliability of operation, it is equipped with an asynchronous microgenerator, the gas-liquid mixture phase sensor is made in the form of parallel plates of 1X electrical capacitors, and the valve is equipped with an electromagnet, and the capacitors plates installed in the internal cavity of the pipeline and connected to the input of an asynchronous microgenerator, the output of which is connected to the input of the relay, in turn connected to the valve electromagnet.
