Description

полненне упрощает конструкцию клала на.Completely simplifies the design of the lay.

На чертеже показан клапан з продольном разрезе.The drawing shows a valve with a longitudinal section.

3 корпусе 1 кл:апана помешен диффеэени1 а;ьный поршень 2 с центральным каналом 3 определенного диаметра. Верхний край поршн  представл ет собою уплотнительную затворную поверхность 4. Эта поверхность притерта к гнезду корлуса, а нгружна  лозерхность 5 поршн  притерта к стенкам корпуса. Поршень прижимаетс  к гнезду 6. Величина открыти  клапана регулируетс  упором 7 л регулировочной прокладкой 8. Снизу на корпус лавинчена крышка .9.3 body 1 cell: Apana is displaced by differential; a piston 2 with a central channel 3 of a certain diameter. The upper edge of the piston is the sealing surface 4. This surface is ground to the socket of the corlus, and the external surface of the piston 5 is ground to the walls of the housing. The piston is pressed against the seat 6. The opening value of the valve is regulated by an emphasis of 7 liters with an adjusting gasket 8. A cover is avalanched to the body from below.

Открытие клапана происходит за счет разницы в диаметрах поршн  и уплотнительной затворной поверхности. Величина давлени , пр.и которой клапан открываетс , зазисит от величины зтой разности и от vci-пи  предварительного поджати  пружины. После открыти  клана);; на затворную ллощ.адь начинает действовать давление, которое увеличивает открытие клапана и сжатие пружины. Давление передаетс  на нижнюю поверхность поршн  через центральный канал п клапан начинает заигрыватьс . центрального канала выбирают таким образом , чтобы клапан непрерывно пропускал среду (газ или жидкост; под заданным давлением, причем между давлением редуцируемой и редудЕрованн-ой среды сохран етс  посто нное соотношение.The opening of the valve occurs due to the difference in diameters of the piston and sealing sealing surface. The magnitude of the pressure, the pressure of which the valve opens, will depend on the magnitude of this difference and on the vci-pi spring preload. After opening the clan) ;; pressure begins to act on the valve plate, which increases the opening of the valve and the compression of the spring. The pressure is transmitted to the lower surface of the piston through the central channel and the valve begins to flirt. The central channel is chosen in such a way that the valve continuously passes the medium (gas or liquid; under a predetermined pressure, and a constant ratio is maintained between the pressure of the reduced and the reduced media).

EL: Enlarge reduction to a reduced medium (gas or liquid) with a piston slide, o and t, and so that, to simplify the design, the valve made in the form of a spring loaded differential; an active piston with a central channel of a certain diameter, the upper edge of the piston being a sealing sealing surface.
