Abstract

FIELD: machine building.
SUBSTANCE: invention relates to valve construction and is designed as a check valve for shutting off a flow passage of a pipeline with a flow of working agents. A check valve includes housing (1). Inside housing (1) there is counter cone (2) with inclination angle (α) of 25° to 45°, which is provided with through holes (4) for working agent and with pin (7) of conical valve head (6), which is freely fixed in hole (5), with angle (β) that is smaller than or equal to angle (α) of counter cone (2). Pin (7) of conical valve head (6) with support surface (3) is equipped with conical spring (8), and coaxially connected to conical valve head (6) along one of the sides of support surface (3).
EFFECT: improving operating reliability of a valve for working agents with high flow rate at opening and closing.

Description

Предметом данного изобретения является обратный односторонний клапан для рабочих веществ с высокой частотой расхода, в частности, с параллельным импульсным расходом.The subject of this invention is a one-way check valve for working substances with a high flow rate, in particular with a parallel pulse flow.

Известные обратные односторонние клапаны, характеризующиеся по строению большими габаритами и не подходят для применения для рабочих веществ с высокой частотой расхода при открывании и закрытии (см., например, патент US 4712619 A, кл. F16K 15/06, 15.12.1987).Known one-way check valves, which are characterized by their large dimensions and are not suitable for use with high flow rates when opening and closing (see, for example, US Pat. No. 4,712,619 A, class F16K 15/06, 12/15/1987).

Целью данного изобретения является создание одностороннего обратного клапана, который можно будет применять для рабочих веществ с высокой частотой расхода при открывании и закрытии.The aim of this invention is the creation of a one-way check valve, which can be used for working substances with a high flow rate when opening and closing.

Согласно данному изобретению обратный клапан характеризуется тем, что имеет корпус, внутри которого находится контрконус (гнездо клапана) с углом наклона опорной поверхности „α" от 25° до 45°, оснащенный сквозными отверстиями для рабочего вещества; в ведущем отверстии свободно закреплен стержень конической клапанной головки с углом „β", который меньше или равняется углу „α" контрконуса, причем стержень конической клапанной головки, оснащенной конической пружиной, соосно соединен по одной из сторон опорной поверхности с конической клапанной головкой. Коническая пружина клапана имеет форму конической спирали, отдельные витки которой входят в соседние витки таким образом, что после сжатия толщина конической пружины равняется толщине одного витка. При этом указанные величины угла наклонной поверхности „α" были определены экспериментальным путем, и при выходе за пределы указанных величин, технический результат, достигаемый заявленным изобретением, наблюдаться не будет.According to this invention, the non-return valve is characterized in that it has a housing inside which there is a counter-cone (valve seat) with an angle of inclination of the support surface “α” from 25 ° to 45 °, equipped with through holes for the working substance; a conical valve shaft heads with an angle "β", which is less than or equal to the angle "α" of the counter-cone, and the shaft of the conical valve head equipped with a conical spring is coaxially connected on one side of the bearing surface with a conical valve The conical spring of the valve has the shape of a conical spiral, individual turns of which are included in adjacent turns so that after compression the thickness of the conical spring is equal to the thickness of one turn. Moreover, the indicated angles of the inclined surface "α" were determined experimentally, and upon exit beyond the specified values, the technical result achieved by the claimed invention will not be observed.

Предмет данного изобретения представлен в виде образца на фигурах:The subject of this invention is presented in the form of a sample in the figures:

фиг.1 - осевое сечение обратного клапана,figure 1 is an axial section of a check valve,

фиг.2 - осевое сечение через корпус клапана,figure 2 is an axial section through the valve body,

фиг.3 - корпус клапана со стороны конической клапанной головки,figure 3 - valve body from the side of the conical valve head,

фиг.4 - коническая клапанная головка со стержнем - вид сбоку,figure 4 - conical valve head with a rod - side view,

фиг.5 - вид конической клапанной головки со стороны конического стержня.5 is a view of a conical valve head from the side of the conical rod.

Как показано на фигурах, у обратного клапана есть корпус 1, внутри которого находится контрконус (гнездо клапана) 2 с углом наклона α от 25° до 45°, имеющий сквозные отверстия 4 для рабочего вещества и свободно закрепленный в ведущем отверстии 5 стержень 7 конической клапанной головки 6 с углом β, меньшим или равным углу α контрконуса 2. Стержень 7 конической клапанной головки 6 с опорной поверхностью 3, оснащенной конической пружиной 8, закрепленной в контрконусе 9, по одной из сторон опорной поверхности 3 соосно соединен с конической клапанной головкой 6. Коническая пружина 8 имеет форму конической спирали, отдельные витки которой входят в соседние витки таким образом, что после сжатия толщина конической пружины 8 равняется толщине одного витка 10.As shown in the figures, the check valve has a housing 1, inside of which there is a counter-cone (valve seat) 2 with an angle of inclination α from 25 ° to 45 °, having through holes 4 for the working substance and a rod 7 of the conical valve freely mounted in the leading hole 5 the head 6 with an angle β less than or equal to the angle α of the counter cone 2. The shaft 7 of the conical valve head 6 with a support surface 3 equipped with a conical spring 8 fixed in the counter cone 9 is coaxially connected to the conical valve head on one side of the support surface 3 6. Conical spring 8 has the shape of a conical spiral, individual turns of which are included in adjacent turns in such a way that after compression, the thickness of the conical spring 8 is equal to the thickness of one coil 10.
