Description

КЛИНОВАЯ ЗАДВИЖКА С ДВУДИСКОВЫМ ЗАТВОРОМWEDGE VALVE WITH DOUBLE DISC GATE

1one

Изобретение относитс  к промышленной трубопроводной арматуре.This invention relates to industrial pipe fittings.

Известна клинова  задвижка с двудиско1ВЫМ затвором, шарнирно закрепленным на к-рестовине, котор а  подвешена к т ге.The well-known wedge gate valve with a double-disk shutter, hinged to the restaurant, is hung to the tractor.

Недостатком таких задвижек  вл етс  ненадежность работы затвора, обусловленна  сложностью конструкции т ги.The disadvantage of such valves is the unreliability of the valve, due to the complexity of the design of the rod.

Предлагаема  клинова  задвижка с двудисковым затвором отличаетс  от известных тем, что боковые концы ее крестовины снабжены щеками, вход щими в дисков затвора и удерживающими их от развала. Т га имеет Т-образную форму, и ее боковые концы скольз т по направл ющей корпуса, предохран   диски затвора от |развала щеками при нагрузке проводимой средой и П(ридава  зат1вору форму клина.The proposed wedge latch with a double disc gate differs from those known in that the lateral ends of its crosses are provided with cheeks that enter the gate discs and keep them from falling apart. The T hectare is T-shaped, and its lateral ends slide along the guide casing, the valve discs protect the bolt from collapsing with its cheeks under load with a conducting medium and P (Ridawa wedge-shaped wedge.

Па чертеже изображена предлагаема  клинова  задвижка с двудисковым затвором, общий вид и разрезы по А-А 1И Б-Б.Pa the drawing shows the proposed wedge gate valve with a double-disk valve, a general view and sections along AA-1 and BB.

Задвижка включает в себ  корпус 7 с направл ющими 2, диски 3, объединенные т гойThe valve includes a housing 7 with guides 2, discs 3, combined by a thrust

4, шпиндель 5, подн тник 6, грибок 7, щеки 8, регулирующие прокладки 9.4, spindle 5, lift 6, fungus 7, cheeks 8, regulating pads 9.

Щеки 8, вход щие в пазы дисков 3, соединены с боковыми концами т ги 4. Они предотвращают диски затвора от развала и придают затвору клиновидную форму. Положение щек 8 в пазах регулируетс  с помощью прокладок 9.The cheeks 8, which enter the grooves of the discs 3, are connected to the lateral ends of the pull rod 4. They prevent the shutter discs from falling apart and give the shutter a wedge-shaped shape. The position of the cheeks 8 in the grooves is adjusted with the pads 9.

При движении шпиндел  5 вверх вместе с т гой происходит открывание задвижки. Нагрузка с дисков 3 передаетс  при этом на т гу 4, вход щую своими вертикальными пазами в направл ющие 2. Аналогично происходит закрывание задвижки.When the spindle 5 moves upwards, the valve opens when the valve is opened. The load from the discs 3 is transmitted in this case to the mr 4, which, with its vertical grooves, enters into the guides 2. Similarly, the valve closes.

Предмет изобретени Subject invention

Клинова  задвижка с двудисковым затвором , щарнирно закрепленным на крестовине, котора  подвешена к т ге, отличающа с  тем, что, с целью .повышени  надежности закрывани , боковые концы крестовины снабжены щеками , вход щими в пазы дисков зат-вора и удерживающими их от развала.A wedge valve with a double-disk valve hinged on a cross, which is suspended from a rod, characterized in that, in order to increase the reliability of closing, the lateral ends of the cross are provided with cheeks that enter the grooves of the rear-drive disks and prevent them from falling apart.
