Abstract
1. Клапан газоплотный для пробоотборной емкости, содержащий основание, корпус, по меньшей мере, четыре уплотнительных кольца из полимерного упругого материала и шпиндель с золотником, причем шпиндель выполняет также роль ручки клапана для управления газовыми потоками и роль канала для газовых потоков, отличающийся тем, что на шпинделе с золотником сформированы два паза для двух уплотнительных колец, причем упомянутые пазы и части основания и корпуса клапана, к которым прилегают уплотнительные кольца шпинделя с золотником в открытом и в закрытом положении клапана, имеют форму, соответствующую форме этих уплотнительных колец, между упомянутыми пазами на шпинделе находится резьба, посредством которой соединены основание и шпиндель и осуществляется перемещение золотника при вращении ручки клапана, канал для газовых потоков внутри клапана заканчивается выполненным перпендикулярно его оси отверстием, через которое проходят в (из) канал газовые потоки, в той части шпинделя, где находится резьба, причем в упомянутых пазах располагаются уплотнительные кольца из полимерного упругого материала с низкой газопроницаемостью, обеспечивающие возможность «промывки» газом носителем или отбираемым в пробоотборную емкость газом «мертвых» объемов клапана, другие два уплотнительные кольца из полимерного упругого материала размещаются между основанием и корпусом клапана по обе стороны стенки пробоотборной емкости.2. Клапан по п. 1, отличающийся тем, что основание и корпус соединяются путем защелкивания, образуя неразъемное соединение, за счет выступающих элементов на обеих упомянутых частях, обеспечивая надежное сочленение.3. Клапан по п. 1,1. A gas tight valve for a sampling vessel, comprising a base, a housing, at least four o-rings made of polymer elastic material and a spindle with a spool, the spindle also serving as a valve handle for controlling gas flows and the role of a channel for gas flows, characterized in that two grooves are formed on the spindle with the spool for two o-rings, said grooves and parts of the base and valve body to which the o-rings of the spindle and spool are adjacent in open and in in the open position of the valve, they have a shape corresponding to the shape of these o-rings, between the grooves on the spindle there is a thread through which the base and spindle are connected and the valve moves when the valve handle is rotated, the channel for gas flows inside the valve ends with an opening made perpendicular to its axis, through which flows into (from) the channel gas flows in the part of the spindle where the thread is located, moreover, in the mentioned grooves there are O-rings made of polymer of other material with low gas permeability, providing the possibility of "flushing" with gas by the carrier or gas of "dead" valve volumes taken into the sampling tank, the other two o-rings of polymer elastic material are placed between the base and the valve body on both sides of the wall of the sampling tank. 2. The valve according to claim 1, characterized in that the base and the body are connected by snap-fit, forming an integral connection, due to the protruding elements on both of these parts, providing a reliable joint. The valve according to claim 1,
