Изобретение относитс к арматур ос троению .This invention relates to valves.

Известен дренажный кпааан с выдержкой Ефемени, имеющий камеру рабочего давлени с выпускным отверстием, аккумул тор давпе ни ;(сипьфон), совдиненный с камерой рабочего давпени через устройство задержки времени, промежуточную камеру с выпускным отверстием 1.,A known Epameni drainage valve has a working pressure chamber with an outlet, a pressure accumulator; (syphon) combined with a working pressure chamber through a time delay device, an intermediate chamber with an outlet 1.,

Однако величина давпени в, аккумул торе необходима дл срабатывани клапана, зависит от величины рабочего давлени .However, the amount of pressure in the accumulator, which is necessary for the valve to operate, depends on the value of the operating pressure.

В промышленности используютс клапаны дл выдержки сосудов под давлением, в которых герметизирующим элементом вл ет с мембрана, принудительно прорываема ударником, отдел юща рабочую камеру от промежуточной. Клапаны снабжены камерой накоплени давлени в виде сильфона 23.In industry, valves are used for holding pressure vessels, in which the sealing element is a membrane, forcibly penetrated by a hammer, separating the working chamber from the intermediate one. The valves are provided with a pressure chamber in the form of a bellows 23.

Hefaостатком этого устройства вл етс нестабильна величина нижнего предела рабочего давлени .The hefa of this device is the unstable value of the lower limit of the operating pressure.

Дл расширени диапазона рабочих давлений аккумул тор давлени выполиен в виде камеры с жесткими стенками и разрывной To extend the range of operating pressures, the pressure accumulator is blended as a chamber with rigid walls and a burst

мембраны, отдел ющей его от промежуточной камеры.the membrane separating it from the intermediate chamber.

На чертеже изображен автоматический временной клапан, разрез.The drawing shows an automatic time valve, a slit.

Claims

It consists of a housing 1 with inlets 2, an outlet 3 and a working pressure chamber 4. A forced breakthrough membrane 6 is pressed against the housing with the threaded sleeve 5. The cavity of the threaded sleeve forms an intermediate chamber 7 connected through the holes in the sleeve and the outlet 3 with the atmosphere and containing the piston 8 with the needle 9 loaded with a spring 10. A washer 11 with a calibrated hole is placed on the threaded sleeve 5. The rupture membrane 12 is pressed against the case 1 by a nut 13. A cover 14 is screwed onto the case 1, forming the cavity of the pressure accumulator 15. The pressure accumulator 15 is connected to the operating pressure chamber 4 by a channel 16, in the expansion part of which a time delay device 17 is installed, which is a choke, we made up as a porous filter. When the medium is supplied under pressure through the inlet openings 2 to the chamber 4 of the working pressure, the medium through the cannap 16 and the time delay device 17, P1X, is blunt in pressure / pressure. After a required period of time, determined by the time delay device 17, the medium pressure in the battery 15 is equal to (x: throbbing, necessary for breaking the membrane 12; the membrane breaks through. The energy accumulated in the pressure accumulator in the pressure accumulator piston 8) the needle 9 is moved, the spring 10 is squeezed, while the needle breaks through the meme & wound 6 of the forced breakthrough. The medium flows into the intermediate chamber 7 and then through the hole in the threaded hole 5 and the outlet 3 of the housing 1 flows out of the valve. An automatic time valve containing the working pressure chamber, separated from the intermediate chamber by a forced-breakthrough membrane and connected to the accumulator of the pressure worm, a time delay device made in the form of a channel with a throttle that records the working pressure range, the accumulator pressures Recaptured in the form of a chamber with rigid walls and an amp & jerv of the membrane separating it from the intermediate chamber.
