Description

Известные приспособлени  дл  отмеривани  различных вредных жидкостей пневматическим способом имеют недостатки: они не дают возможности работать без визуального наблюдени , забирать и сливать жидкости с различными объемными скорост ми, работать попеременно, то как ручным, то как стационарным приспособлением.The known devices for measuring various harmful liquids by the pneumatic method have drawbacks: they do not allow to work without visual observation, to pick up and drain liquids with different space velocities, to work alternately, then manually, or as stationary devices.

В описываемом устройстве указанные недостатки устранены. Оно состоит из кожуха с помещенным внутри упругим резиновым баллоном и отличаетс  от ранее известных тем, что, с целью полуавтоматического дозировани  на рассто нии и без визуального наблюдени , в кожухе устройства над баллоном помещен резьбовой с ограничительными упорами щток, один конец которого соединен с электроприводом, а другой оканчиваетс  самотормоз щей гайкой, имеющей фрикционное соединение с корпусом дозирующего устройства.In the described device, these disadvantages are eliminated. It consists of a casing with an elastic rubber balloon placed inside it and differs from the previously known ones in order to semi-automatically dispense at a distance and without visual observation, in the casing of the device above the balloon there is a threaded brush with restrictive stops, one end of which is connected to an electric drive, and the other ends with a self-locking nut having a frictional connection with the housing of the metering device.

На чертеже изображено дозирующее устроргство, состо щее из резинового баллона 1, заключенного в кожух из металла или из пластмассы , который свинчиваетс  из двух половин верхней 2 и нижней 3, переходного конуса 4 с жесткой обоймой 5 дл  ввода в него хвостовика обычных или специальных химических пипеток.The drawing shows a metering device consisting of a rubber cylinder 1 encased in a metal or plastic casing, which is screwed from the two halves of the upper 2 and lower 3, the transition cone 4 with a rigid holder 5 for inserting the shank into it with conventional or special chemical pipettes .

Дл  сжати  резинового баллона при сливании жидкости служит щток 6, расположенный в гладкостенном, цилиндрическом направл ющем канале верхней части корпуса. Нижний конец щтока снабжен свободно вращающейс  «а цапфовом винте 7 нажимной щайбой 8. Верхний конец штока имеет две головки 9 и 10.To squeeze the rubber bottle when draining the liquid, a brush 6 is used, located in the smooth-walled, cylindrical guide channel of the upper part of the housing. The lower end of the stem is provided with a freely rotating pin 7 screw on the push-pull plate 8. The upper end of the stem has two heads 9 and 10.

На средней части щтока нанесена шкала с делени ми, дл  грубой установки определенных доз и нарезана винтова  нарезка. С помощью этой нарезки щток может перемещатьс  относительно упорной гайки П. Головка 9 служит дл  быстрого вращени  щтока вручную, а также от синхронного электродвигател  СД-60 путем укреплени  выходного валика редуктора в отверстии головки винтом 12.A scale with divisions is applied on the middle part of the brush, for coarse installation of certain doses and screw cutting is cut. Using this threading, the brush can move relative to the stop nut P. The head 9 serves to quickly rotate the wheel manually, as well as from the synchronous motor SD-60 by strengthening the output roller of the gearbox in the head hole with a screw 12.

Головка 10 служит дл  медленного вращени  щтока вручную, а также от синхронного электродвигател  СД-2 путем укреплени  валика редуктора винтом 13, кроме того головка 10 служит одновременноThe head 10 serves to slowly rotate the brush manually, as well as from the synchronous motor SD-2 by strengthening the reduction gear shaft with a screw 13, besides the head 10 serves simultaneously
