Description

(54) ПРЕДОХРАНИТЕЛЬНЫЙ КЛАПАН(54) SAFETY VALVE

орган 4 возвращаетс  к седлу 2 и выдавливает жидкость из демпферной полости 7 через зазор 5 при закрытом обратном клапане 9.the organ 4 returns to the saddle 2 and squeezes the fluid out of the damping cavity 7 through the gap 5 with the non-return valve 9 closed.

Предлагаемый предохранительный клапан по сравнению с известными более надежен за счет устранени  воздействий на плавность закрыти  затвора сил пульсирующего давлени  в сливной линии, увеличени  сопротивлени  демпфирующего устройства, по мере приближени  затвора к седлу (возрастает длина зазора) и улучщени  условий открыти  клапана (демпферное устройство свободно заполн етс  жидкостью, поскольку обратный клапан открываетс  давлением в напорной магистрали до начала открыти  запорного органа, а зазор 5 посто нно за полнен жидкостью, играющей роль смазки).The proposed safety valve is more reliable than the known ones by eliminating the effects on the smoothness of closing the gate of the pulsating pressure in the drain line, increasing the resistance of the damping device as the valve approaches the saddle (the length of the gap increases) and improves the opening conditions of the valve (damper free filling liquid, since the non-return valve opens with pressure in the pressure line prior to the opening of the closure member, and the gap 5 is continuously filled with liquid playing the role of lubricant).
