Abstract

Изобретение относитс к машиностроению и может использоватьс в различных отрасл х народного хоз йства . Целью изобретени вл етс повышение точности дозировани высоков зких веществ. В бункер 2 загружаетс продукт в упаковке, и под действием силы Р, приложенной к крышке бункера, опускаетс . Упаковка автоматически вскрываетс ножом 4. Продукт ., вытека из упаковки, заполн ет предцилиндровую камеру 3. Шток 9 совершает возвратно-поступательные движени . При движении штока вправо поршень 10 захватывает порцию материала и подает его в полость цилиндра 5. При дальнейшем движении поршн материал выдавливаетс через клапан 13 и через отверстие в штуцере 15. Доза материала зависит от объема полости цилиндра 5, который регулируетс резьбовой втулкой 11. 1 ил. toThe invention relates to mechanical engineering and can be used in various industries of the national economy. The aim of the invention is to improve the metering accuracy of highly viscous substances. The hopper 2 is loaded with the product in the package, and under the action of the force P applied to the bunker lid, is lowered. The package is automatically opened by the knife 4. The product, which flows out of the package, fills the pre-cylinder chamber 3. The rod 9 reciprocates. When the piston moves to the right, the piston 10 captures a portion of the material and feeds it into the cavity of the cylinder 5. With further piston movement, the material is squeezed through the valve 13 and through the opening in the fitting 15. The dose of material depends on the volume of the cavity of the cylinder 5, which is regulated by the threaded sleeve 11. 1 or . to

Изобретение относитс к машиностроению , в частности к устройствам дл дозированной подачи в зких материалов , и может примен тьс в различных област х промьппленности.The invention relates to mechanical engineering, in particular to devices for dispensing viscous materials, and can be applied in various industrial areas.

Целью изобретени вл етс повьппе- ние точности дозировани высоков зких веществ.The aim of the invention is to improve the dosage accuracy of highly viscous substances.

На чертеже изображен предлагае- мый насос-дозатор, общий вид, разрезThe drawing shows the proposed metering pump, general view, section

Вьшолнение торцовой стенки цилиндра , в которой расположен клапан, в виде втулки с резьбовым участком дл изменени длины цилиндра позвол ВТ дозировать в зкий материал с высокой степенью точности и регулировать количество подаваемого материала.Performing the end wall of the cylinder in which the valve is located, in the form of a sleeve with a threaded section to change the length of the cylinder, allows the BT to dispense the viscous material with a high degree of accuracy and adjust the amount of material supplied.

Насос-дозатор состоит из корпусаThe metering pump consists of a casing

1, бункера 2, предцилиндровой каме- 20 штуцера 15. Доза материала зависит1, hopper 2, pre-cylinder chamber 20 of fitting 15. The dose of material depends

ры 3 с ножом А и цилиндра 5. В бункере 2 находитс продукт 6, закрытый крьщ1кой 7. Бункер, 2 и крьш1ка 7 имеют отводы 8 дл выхода воздуха. В корпусе 1 установлены с возможностью пе- 25 ремещени шток 9 с подвижно расположенным на нем поршнем 10 и втулка 11 с резьбовым участком с контргайкой 12. Внутри втулки II установлен клапан 13 с пружиной 14, которые Q удерживаютс штуцером 15. В нижней части корпуса 1 расположен кран 16.3 with a knife A and a cylinder 5. In the hopper 2 there is a product 6, which is closed by a bolt 7. The bunker, 2 and a bolt of 7 7 have outlets 8 for air to escape. In case 1, a rod 9 with a movable piston 10 and a sleeve 11 with a threaded section with lock nut 12 is mounted for movement 25. Inside valve II there is a valve 13 with a spring 14, which Q is held by fitting 15. At the bottom of the case 1 located crane 16.

Claims

from the volume of the cavity of the cylinder 5, which is adjusted by the threaded sleeve

A metering pump containing a pre-cylinder chamber, a piston and a cylinder, characterized in that, in order to improve the metering accuracy of highly viscous substances, the end wall of the cylinder including the valve is designed in the form of a sleeve with a threaded portion for changing for a cylinder.

The device works as follows.

The hopper 2 loads product 6. packaged. When the valve 16 is opened and the outlet 8 of the cap 7 is applied, pressure P is applied, as a result of which the product bag is lowered, the bag is opened with knife 4 and the material flowing out of the bag fills pre-cylinder chamber 3. After filling the chamber 3 with material 8, the ends 8 and the valve are filled. , I 6 overlap. The rod 9 reciprocates. When moving the rod to the right, the piston 10 captures a portion of the material and feeds it into the cavity of the cylinder 5. With further movement of the piston, the material pushes through the valve 13 and through the hole

the volume of the cavity of the cylinder 5, which is adjusted by the threaded sleeve 1 1 The formula of the invention

A metering pump containing a pre-cylinder chamber, a piston and a cylinder, characterized in that, in order to improve the metering accuracy of highly viscous substances, the end wall of the cylinder including the valve is made in the form of a sleeve with a threaded portion for changing the length of the cylinder.
