成果简介	NOVELTY - The element has a channel for supplying a liquid medium between a shutter (1) and a seat (4). The shutter is made with conical and cylindrical sections, and the channel supplying the liquid medium is formed between the cylindrical part of the shutter and the seat. The shutter and seat are placed in a sleeve (3) with openings made along length of a shutter stroke and connecting the channel for supplying the liquid medium with the working cavity of the valve, where maximum diameter of the conical section of a bolt corresponds to an inner diameter of the sleeve, and the cylindrical sections of the valve is made with a length that exceeds the diameter by two times. USE - Shut-off and control element for a valve for metered supply of a liquid medium i.e. chemical reagent, in a oil and gas production field for introducing various chemical reagents during work on developing and testing oil and gas wells i.e. underwater wells. ADVANTAGE - The element increases the accuracy of dosing of the liquid medium by a dosing valve. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a fragment of a valve design with a shut-off and control element. 1Shutter 2Rod 3Sleeve 4Seat 9Body 11Flow meter
