Abstract
Изобретение относитс к арматуростроению и может быть использовано при создании запорных устройств дл трубопроводов большего диаметра Целью изобетени вл етс повышение долговечности уплотнительного элемента заслонки за счет выполнени по периметру седловой поверхности 2 отверстий 7. закрытых кожухом 8, сообщающимс с высоконапорным и низконапорным патрубками, а также выполнени уплотнитепьного элемента в виде двух трубчатых полуколец 13 и 14. сообщенных с высоконапорным патрубком 2 ил.The invention relates to valve engineering and can be used to create locking devices for pipelines of larger diameter. The purpose of the invention is to increase the durability of the sealing element of the valve due to the perimeter of the saddle surface 2 holes 7. closed by a casing 8, communicating with high-pressure and low-pressure pipes, as well as tighten the bottom element in the form of two tubular half rings 13 and 14. connected with a high-pressure pipe 2 il.
