RU77461U1 - HIGH PRESSURE LIQUID OR GAS FLOW REGULATOR - Google Patents

Abstract

Wafer flow regulator for high (up to 320 kgf / cm2) pressure (liquid and gas containing solid particles) with a nominal passage from 0 to 30 (65) mm - two-chamber multi-channel (multi-spindle) single-case locking and regulating device of a discrete type with semi-automatic manual control .

The regulator performs the functions of: locking (latches), regulating the flow of the working medium and the impact on changes in oil recovery; they are installed on water conduits and injection well fittings, in a water distribution comb block in cluster pumping stations instead of: ZMSh65x210 (ZMS65x210) valves with a fitting; gate valves ZDSh65h210, ZDSh-5-65h210 - revolving type, ball valves with ceramic inserts KShD-20h210.

The interflange flow regulator is formed by an inlet dividing choke chamber and an output collection chamber, which are interconnected by a cylinder-shaped body with several (for example, four) parallel channels with spindles and handles individually for each ball plug for opening and closing each channel by 90 ° rotation. On the part of the dividing chamber, the housing channels have special sockets for installing replaceable ceramic bushings with throttle openings from 2 to 20 mm or more. At the same time, turning the knobs through 90 ° causes the controller to overlap, reversing all the knobs ensures maximum passage of the medium, and by combining the number of open-closed channels, the fluid flow is regulated: in time from a fraction of a minute or more; flow rate from DN 0 mm to DN equal to the total cross-sectional area of the throttle holes of the bushings.

Description

An interflange flow regulator for pressures up to 320 kgf / cm2 refers to discretely regulating flow of liquid (gas) shut-off and control devices and can be used in many industries to quickly change the flow rate and pressure of the working medium.

The main application of the regulator is in the production of working fluids with mechanical impurities associated with pipeline transportation under high pressure, including in systems for maintaining reservoir pressure in oil production.

Known flow controllers (1), working to change the total flow area by combining the state of the valves on the saddles of the control elements.

However, such a device is designed to control the gas flow in vacuum systems, that is, with a low pressure and a clean working medium that does not have mechanical or other impurities. In addition, the design is quite complex and not reliable enough (referring to the spring mechanism).

Known regulators or gate valves with quick-change fittings having throttle openings from 2 to 12 mm and 32 mm (2), including a revolving type.

The disadvantages of the choke valve are: a narrow range of regulation of nominal bore (from 2 to 12 mm and 32 mm); the inability to simultaneously use several fittings or all at once or their combined use to achieve the maximum number of options for the total flow area of the regulator; the need to block the conduit before changing the fitting; creating a water hammer on a liquid column in an injection well with a height of 1,500 or more meters; manual control of the valve (change of fittings). An increase in the number of fittings with a diameter from 25 mm to 65 mm on this device would lead to

a sharp increase in its dimensions and weight, which is not permissible from the point of view of embedding the overall valve in standard structural elements of wellhead valves or pipelines.

Automated fluid flow controllers (3) are known, which are union-crane devices in which the combination of the total bore of the nozzle openings is carried out by opening and closing ball valves.

The disadvantage of regulators is the significant metal consumption of the structure and cost.

The purpose of this proposal is to simplify the design, reduce the time it takes for the fluid to pass from the inlet to the outlet, reduce water losses at the outlets and transitions, and reduce costs.

The wafer flow regulator is formed by inlet 2 and outlet 9 flanges, interconnected by a spherical device (housing) 4 in the form of a cylinder with several (for example, four) parallel channels with 6 spindles 7 for each ball plug 6 and handles 10 for opening and closing each channel 90 ° rotation. On the input flange 2 side, the channels of the housing have special sockets for installing replaceable ceramic bushings 3 with throttle openings from 2 to 20 mm or more. The ends of the housing 4 have the shape and purpose of the sealing interflange ring (gasket) due to which the housing is clamped between the flanges 2 and 9 with the pins 1 and nuts, forming a locking and regulating device (regulator).

The regulator works as follows: in accordance with the technological map of modes, the opening of all channels ensures quick filling of the regulatory object, for example, water conduits to the reservoir; the overlapping of all channels ensures that the device operates as “closed”, and the combination of the number of open-closed channels

allows you to adjust the fluid flow: in time from a fraction of a minute or more; consumption: from DN 0 to DN equal to the total area of the holes of the bushings. (Du - conditional diameter).

The number of possible combinations of the total cross-section is several tens, and the discreteness of regulation in volume (flow) allows for program-controlled maintenance of reservoir pressure during oil production.
