Description

(54) КЛАПАН(54) VALVE

7 прижимаетс  к седлу 6, Запорна  мембрана 4 продавливаетс  через центральное отверстие 9 в дополнительной мембране 7 и уплотн ет канал 2 в корпусе 1,7 is pressed against the seat 6, the closure membrane 4 is forced through the central opening 9 in the supplemental membrane 7 and seals the channel 2 in the housing 1,

После выравнивани  давлений в каналах 2 и 3 дополнительна  мембрана 7 возвращаетс  в первоначальное положение, отодвига  при этом запорную мембрану 4 от седла 6 и перевод  клапан в открытое положение .After equalizing the pressures in channels 2 and 3, the additional membrane 7 returns to its original position, while removing the locking membrane 4 from the seat 6 and moving the valve to the open position.

В предлагаемом клапане запорна  мембрана 4 зажата без раст жени  в радиаль ном направлении, поэтому изменение ее свойств не вызывает нестабильность характеристик клапана во временИо Величина расхода, при котором срабатывает клапан также более стабильна, индивидуальные характеристики клапанов удовлетвор ют требовани м взаимозамен емости. Врем  стабильной работы клапана приблизительноIn the proposed valve, the locking membrane 4 is clamped without stretching in the radial direction, therefore a change in its properties does not cause instability of the valve characteristics in time. The flow rate at which the valve operates is also more stable, the individual characteristics of the valves meet the requirements of interchangeability. Valve stable operation time approximately

вдвое больше времени стабильной работы известного клапана, а колебани  величины расхода срабатывани  от цикла к циклу уменьшены на пор док.twice the stable operation time of a known valve, and fluctuations in the magnitude of the flow rate from cycle to cycle are reduced by an order of magnitude.

Формула изобретени Invention Formula Клапан, в составном корпусе которого, снабженного осевыми проходными каналами установлена запорна  мембрана с отверсти ми , отличающийс  тем, что, с целью обеспечени  стабильного перекрыти  при достижении определенного расхода, в полости корпуса выполнен кольцевой выступ,  вл ющийс  седлом, между которым и запорной мембраной размещена дополнительна  мембрана повышенной жест кости с прорез ми по периферии и центральным отверстием, диаметр которого больше диаметра седла.The valve, in the composite casing of which, provided with axial flow passages, is installed a shut-off diaphragm with holes, characterized in that, in order to ensure a stable shut-off when a certain flow rate is reached, an annular protrusion is made in the body cavity, which is located an additional stiffened membrane with cuts along the periphery and a central aperture, the diameter of which is larger than the diameter of the saddle. gg 0u.J0u.J
