LOCKING AND REGULATING DEVICE WITH ELECTROMAGNET Russian patent published in 2021 - IPC F16K31/05 F16K39/02 

FIELD: oil and gas industry

SUBSTANCE: invention relates to the oil and gas industry and can be used for remote shut-off of the flow of the working medium on the flow line of a gas well. A locking and regulating device with an electromagnet include a housing with an internal cavity, a shutter, an electromagnetic drive, and a manual override. The device includes a shutter and a small discharge shutter. The shutter is made in the form of a fixed seat, a cage with holes for the passage of the working medium, a plunger assembly connected by a plunger rod with an electromagnet armature through a handwheel rod, a regulating threaded bushing. The cage is installed in the inner cavity of the body and is made with the possibility of pressing against the seat by an adjusting threaded sleeve. The plunger assembly includes a plunger, an adjusting threaded bushing, an upper bushing, a lower bushing, a plunger rod, a lower rod, and the plunger has an internal cavity, a side hole, channels, an outlet channel, an internal threaded hole, the upper bushing has threaded connections with the plunger rod in its upper part and with a lower stem in its lower part, the upper sleeve is also equipped with a spring, which ensures a permanent tight seal of the small loading valve at the point of contact of the tapered sealing surfaces of the upper sleeve and the lower stem, the lower sleeve is screwed into the internal threaded hole of the plunger with fixation between the lower sleeve and the plunger of an O-ring, and the lower sleeve has an O-ring in the upper part of the central hole passing in the lower part into the central threaded hole, a lower stem with a seal is installed in the central hole of the lower sleeve, and a plug with a sealing washer is installed in the central threaded hole of the lower sleeve. A spring is installed in the inner cavities of the adjusting threaded sleeve and plunger. The side hole in the plunger, the channels in the plunger, the outlet channel of the plunger and the plunger bushing form a small unloading valve, the opening and closing of which is provided by the upper bushing made with the possibility of overlapping the side hole of the plunger. The handwheel is installed on the housing cover and is a glass with a central and side holes, a handwheel stem is installed in the central hole, an adjusting unit in the form of a roller is installed in the side hole, rigidly connected to the handle, and the roller is in contact with the bottom end of the manual stem. doubler has an eccentric protrusion, and the eccentric protrusion is made with the possibility of moving the handwheel rod and the associated plunger rod to the uppermost position when the handle is turned from the "closed" position to the "open" position, thereby opening the valve for the medium passage. The electromagnetic drive is fixed to the glass of the manual override and is an electromagnet equipped with an armature position sensor in the extreme off position.

EFFECT: invention provides a high level of tightness, the ability to perform the functions of shutting off the flow of the working medium, both liquid and gaseous, with a high pressure drop across the valve using an electromagnet of the required power due to the use of unloading channel valves in the design of the valves, makes it possible to control the process of closing the working medium both remotely by applying an electrical signal to the electromagnet through the control module from the control room, or manually using a handwheel in the absence of power supply.
