Definitions

  • the invention relates to the field of fluid controllers, in particular to adjustable flow controllers, and can be used in various technical fields to control the pressure difference of a fluid flow with high accuracy, as well as a shut-off, non-return, emergency valve, and for dosed flow fluid flow.
  • the valve can be used as a regulator of the pressure difference of a gas or liquid flow; as a check valve.
  • the valve can also be used as an emergency valve, when the specified pressure of the flow directing through the discharge pipe to the drainage pipe is exceeded.
  • the valve can also be used as a metering valve, capable of smoothly changing the flow rate or stepwise changing the flow rate with a predetermined step depending on the pressure.
  • a pressure differential regulator having an inlet motor control valve, a rod connected to the membrane or bellows, and a space under the membrane in communication with the inlet.
  • the principle of operation of such a regulator is as follows: high pressure in front of the motor control valve is transmitted to the cavity under the diaphragm of the regulator. The average pressure through the channel in the rod is transmitted from the inlet fitting of the regulator into the cavity above its diaphragm. The regulator spring through the diaphragm counteracts the pressure in the lower cavity and, thus, sets the required differential pressure.
  • the objective of the invention is the simplest, most reliable and technologically advanced construction, capable of maintaining a constant pressure drop with high accuracy, and, in addition, capable of having additional functions: reverse and shut-off valve, smoothing pressure pulsation, emergency relief, dosed feed.
  • the technical result is achieved by the fact that inside the valve, in the passage section, a movable load of a fixed weight is installed, with the help of which the differential pressure is regulated.
  • the load has such a shape that, being in the lowest position, closes the completely bore section of the outlet pipe, and being in the highest position also closes the fully bore section of the outlet pipe, but at the same time opens the discharge pipe, for which there is an annular groove on the moving load .
  • the overpressure flow is discharged through the discharge pipe until the pressure drops below a predetermined value, after which the load goes down and the cross section of the discharge pipe is blocked.
  • check and shut-off valves The function of the check and shut-off valves is achieved by the designs of the moving load and the relative position of the moving load and the nozzles of the universal gas-hydraulic valve, due to which the flow of the fluid in the forward direction is possible and the movement in the opposite direction is impossible.
  • the function of smoothing pressure pulsations is achieved thanks to the equalizing drainage hole, which connects the outlet pipe and the space above the moving load, equalizing the pressure in the space above the moving load and in the outlet pipe.
  • the equalizing drainage hole which connects the outlet pipe and the space above the moving load, equalizing the pressure in the space above the moving load and in the outlet pipe.
  • the function of the dosed fluid flow is achieved by designing the outlet pipe in the form of a slotted nozzle for supplying gas to the turbine blades, the opening height of the slotted nozzle being determined by the position of the moving load. Also, the function of the dosed supply of the fluid flow can be achieved by the execution of the outlet pipe in the form of a set of vertically arranged one above the other holes (nozzles) of a given diameter
  • the universal gas-hydraulic valve maintains a differential pressure difference with high accuracy regardless of pressure surges in the network.
  • the rod on the central section of the load, ending with a nut, allows the installation and removal of additional calibration washers with a given weight. This allows you to build up, modify, and also adjust (fine tune) the pressure difference by changing the weight of the load.
  • the advantages of the valve include: maintaining the pressure difference with high accuracy; the ability to fine-tune the pressure difference in the process; extremely simple way to adjust the pressure difference; a reliable and non-volatile control method based on the action of gravity (which allows the valve to be used on objects located in areas of electromagnetic anomalies, either in the absence of a stable power supply, or operating in harsh environmental conditions, or requiring increased reliability); smoothing pressure pulsations at the outlet of the device.

In the lowest position, the movable load completely covers the outlet pipe.
  • the installation method of the universal gas-hydraulic valve is exclusively in the vertical position.
  • the only working position of the valve is vertical.
  • the valve has an equalizing drainage hole connecting the outlet pipe and the space above the movable load, so that the pressure in the space above the movable load is equal to the pressure in the outlet pipe, at the outlet of the valve.
  • the hole is made in the valve body.
  • All nozzles can have threaded connections or “soldered” connections, and for larger diameters, flanged connections.
  • the outlet pipe may be made in the form of a pipe for connection with a pipeline.
  • the outlet pipe may be made in the form of a slotted nozzle for supplying gas to the turbine blades.
  • the valve can be rotated around a vertical axis for optimal interaction as part of a technical device (for example, for an optimal angle of gas supply to the turbine blades).
  • the outlet pipe can be made in the form of a set of vertically arranged one above the other holes (nozzles) of a given diameter, for the device to perform the function of a metering or dispensing valve. With the gradual lifting of the moving load upwards, the openings turn out to be open one after the other, while lowering the moving load the openings are closed.

Abstract

L'invention se rapporte au domaine des régulateurs de milieu en écoulement, notamment de régulateurs de flux ajustables, et peut être utilisée dans divers domaines techniques afin de réguler des différences de pression d'un flux d'un milieu en écoulement avec une grande précision, ainsi qu'en qualité de vanne de fermeture, de retour ou d'urgence, et afin de doser l'alimentation d'un flux d'un milieu en écoulement. Dans la vanne, dans la section de passage, se trouve une charge mobile d'un poids fixe qui permet d'ajuster une chute de pression. Le poids de la charge peut le cas échéant être ajusté par l'installation ou le retrait de rondelles de régulation supplémentaires et, é cette fin, la partie supérieure de la charge mobile comprend une protubérance en forme de tige et de boulon pour fixer les rondelles. Cette à gaz-hydraulique universelle permet d'ajuster des différences de pression avec une grande précision indépendamment des sauts de pression dans un circuit. La vanne peut être utilisée comme régulateur de différence de pression d'un flux de gaz ou de liquide, ou comme vanne de fermeture ou de retour. La vanne peut également être utilisée comme vanne d'urgence lors du dépassement d'une pression donnée du flux dans le conduit de refoulement d'un tube de drainage. La vanne peut aussi être utilisée comme vanne de dosage permettant de modifier en douceur un débit ou de modifier par palier un débit selon un pas donné en fonction de la pression.
