Description

мента контакта тарели с седлом, поэтому неуравновешенные силы давлени  на тарель не по вл ютс .contact between the plate and the saddle, therefore unbalanced forces of pressure on the plate do not occur.

После закрыти  клапана давление из полостей 6 и 7 стравливаетс  в выходную полость 8 через каналы 9.After the valve is closed, the pressure from the cavities 6 and 7 is released into the output cavity 8 through the channels 9.

Таким образом, выполнение в затворе предохранительного клапана канала, св зывающего полость между концентрическими поверхност ми уплотнени  с полостью над разгрузочным поршнем, позвол ет уменьшить разницу между давлени ми открыти  и закрыти .Thus, the passage in the gate of the safety valve of the channel connecting the cavity between the concentric surfaces of the seal with the cavity above the discharge piston reduces the difference between the opening and closing pressures.

Формула изобретени Invention Formula Предохранительный клапан по авт. св. № 402708, отличающийс  тем, что, с целью уменьшени  разницы между давлени ми открыти  и закрыти , в нем установлен соосно с затвором и жестко с ним св зан разгрузочный поршень, надпоршнева  полость которого св зана каналом с разгрузочной камерой .Safety valve on the bus. St. 402708, characterized in that, in order to reduce the difference between the opening and closing pressures, a discharge piston is installed coaxially with the gate and rigidly connected with it, the over-piston cavity of which is connected to the discharge chamber.
