Description

Изобретение касаетс  регул торов дл  подъема давлени  у гидравлических прессов путем подачи жидкости через узкий канал, с применением принудительно управл емых перепускных клапанов дл  периодического пропускани  определенных объемов жидкости,The invention relates to pressure regulators for hydraulic presses by supplying fluid through a narrow channel, using force-controlled relief valves for periodically passing certain volumes of fluid,

В предлагаемом регул торе включен в напорный трубопровод между перепускными клапанами герметически .закрытый резервуар с воздухом с той целью, чтобы жидкость, проход ща  в прессе через узкий канал клапана типа Френча, периодически автоматическим путем омывала последний при поступлении в упом нутый резервуар, с целью предотвращени  засорени  узкого канала клапана.In the proposed regulator, a hermetically sealed air reservoir is included in the discharge pipe between the relief valves so that the fluid passing through the narrow channel of the French-type valve in the press periodically automatically bathes the latter when it enters the reservoir. clogging of the narrow valve channel.

Согласно видоизменению изобретени  во включенный между перепускными клапанами резервуар помещен поршень, а сам резервуар посредством пружинного клапана сообщен с дополнитель ным резервуаром, питаемым сжатым воздухом при помощи другого пружинного клапана.According to a modification of the invention, a piston is placed between a relief valve and a reservoir, and the reservoir itself is connected by means of a spring valve to an additional reservoir fed by compressed air using another spring valve.

На чертеже фиг. 1 изображает схему устройства регул тора; фиг. 2 - устройство клапана дл  впуска в пресс и выпуска из него напорной жидкости в моменты начала и конца прессовани , со (Э61)гласно видоизменению изобретени ; фиг. 3-устройство клапанов дл  впуска в пресс напорной жидкости низкого давлени ; фиг. 4 - устройство клапанов с приводным механизмом дл  впуска напорной жидкости высокого давлени .In FIG. 1 shows a diagram of a regulator device; FIG. 2 shows a valve device for inlet and discharge of pressurized fluid at the press at the beginning and at the end of pressing, according to (E61), according to the invention; FIG. 3-valve arrangement for inlet of low pressure into the press liquid; FIG. 4 shows a valve arrangement with a drive mechanism for admitting high-pressure pressure fluid.

В известной клапанной коробке типа Френча, служащей дл  автоматического переключени  низкого давлени  на высокое , предлагаетс  регулировать, скорость высокого давлени  путем введени  в трубопровод 72, J4, 21, 11 высокого давлени  (фиг. 1) принудительно управл емых перепускных клапанов 15, 18 и между ними воздушного резервуара 2S с клапаном /7 типа Френча, снабженным узким каналом 20. Означенное устройство имеет ту цель, чтобы жидкость проход ща  в прессе ..через узкий 20у периодически автоматическим путем омывала последний при поступлении в резервуар 28, с целью устранени  засорени  канала 20.In the well-known French type valve box, which serves to automatically switch from low to high pressure, it is proposed to regulate the high pressure rate by introducing into the high pressure pipe 72, J4, 21, 11 (Fig. 1) forcibly controlled bypass valves 15, 18 and between they have an air tank 2S with a valve / 7 of the French type, equipped with a narrow channel 20. The device indicated has the purpose of allowing the liquid passing in the press through the narrow 20u to periodically automatically wash the latter when it enters the reservoir voir 28, to eliminate clogging of channel 20.

Трубопровод от аккумул тора низкого давлени  присоедин етс  к каналу трубы 7, а трубопровод от аккумул тора BbicoKoro давлени  к каналу трубы./ труба 77 соедин етс  с цилиндром пресса.The pipeline from the low pressure accumulator is connected to the channel of the pipe 7, and the pipeline from the BbicoKoro accumulator of pressure to the pipe channel. The pipe 77 is connected to the cylinder of the press.

Действие прибора начинаетс  с момента начала подъема давлени  в прессе после полного открыти  з.апорного илаТ JThe operation of the device starts from the moment of the beginning of the pressure increase in the press after the complete opening of the support valve. J
