Description

Изобретение относитс к области устройств , распыл ющих жидкости, в частности дл промывки печатных плат (ПП) в лини х фотохимии, а также в травильных машинах при травлении ПП.The invention relates to the field of devices for spraying liquids, in particular for washing printed circuit boards (PCB) in photochemistry lines, as well as in pickling machines for etching PCBs.

Известное устройство дл очистки теплообменных труб, содержащее насадку, установленную в корпусе с возможностью осевого перемещени на резьбе 1.The known device for cleaning the heat exchange tubes, containing a nozzle mounted in the housing with the possibility of axial movement on the thread 1.

Недостатком его вл етс сложность очистки кольцевой цели в процессе работы и установка заданной щели. При малом угле конуса, образующего факел, равномерность жидкости по образующим конуса различна .Its disadvantage is the difficulty of cleaning the ring target during operation and the installation of a predetermined slit. With a small angle of the cone, forming a torch, the uniformity of the fluid along the cone forming different.

Известна также наиболее близка к изобретению форсунка, содержаща корпус с соплом на его выходном торце и установленную в корпусе с возможностью осевого перемещени насадку 2.Also known is a nozzle closest to the invention, comprising a housing with a nozzle at its output end and an attachment 2 mounted in the housing with the possibility of axial movement.

Недостатком известного устройства вл етс наличие привода, усложн ющего обслуживание форсунки, и ее громоздкость.A disadvantage of the known device is the presence of the actuator, which complicates the maintenance of the nozzle, and its bulkiness.

Цель изобретени - упрощение конструкции форсунки и эксплуатаци ее.The purpose of the invention is to simplify the design of the nozzle and its operation.

Достигаетс это тем, что насадка выполнена в виде стержн с конусообразной гоЛОВКОЙ и выступом с ее наружной стороны, закрепленного на вкладыше с отверсти ми дл прохода жидкости, свободно установленном в корпусе между выполненными в нем упорами, причем диаметр сопла превыщает наибольщий диа.метр головки.This is achieved by the fact that the nozzle is made in the form of a rod with a cone-shaped HEAD and a protrusion on its outer side, fixed on a liner with openings for the passage of fluid, freely installed in the housing between the stops made in it, and the diameter of the nozzle exceeds the largest diameter of the head.

На чертеже изображена форсунка, разрез .The drawing shows the nozzle section.

Форсунка содержит корпус 1 с соплом 2 на его выходном торце и установленную в корпусе 1 с возможностью осевого перемещени насадку.The nozzle includes a housing 1 with a nozzle 2 at its output end and mounted in the housing 1 with the possibility of axial movement of the nozzle.

Насадка выполнена в виде стержн 3 с конусообразной головкой 4 и выступом 5 с ее наружной стороны, закрепленного на вкладыше 6 с отверсти ми 7 дл прохода жидкости, свободно установленном в корпусе 1 между выполненными ь нем упорами 8 и 9.The nozzle is made in the form of a rod 3 with a cone-shaped head 4 and a protrusion 5 on its outer side, fixed on a liner 6 with openings 7 for the passage of fluid, freely installed in the housing 1 between the lugs 8 and 9 made therein.

Диаметр сопла 2 превышает наибольший диаметр головки 4.The diameter of the nozzle 2 exceeds the largest diameter of the head 4.

Форсунка работает следующим образом.The nozzle works as follows.

Claims

When the fluid is supplied, the liner 6 is pressed by the fluid pressure to the stop 8. The fluid passes through the openings 7, enters the chamber and rushes into the nozzle 2 with a flat flow. Meeting on the path of resistance rcxicHi-.n 4, the fluid rushes into mcviii formed by the body and head 4. In the event of a nozzle contamination, it is enough to press the recess 5 so that the head 4 is in the cavity of the housing 1. The foreign body comes out with a fluid flow between the housing 1 and the protrusion 5. Releasing the protrusion 5, the liner 6 automatically under the pressure of the fluid will snap into place, forming the same gap between the housing I and the head 4. The presence of the movable liner allows you to clean the nozzles during operation, which significantly increased the productivity of work on the photochemistry line, in pickling, installation, as there is no need to disable the entire installation due to one nozzle. Invention Nozzle comprising a housing with a nozzle at its output end and an attachment installed in the housing with the possibility of axial displacement, characterized in that, in order to simplify the design of the nozzle and operation, its nozzle is made in the form of a rod with a conical head and a protrusion its outer side mounted on the liner with holes for the passage of fluid, freely installed in the housing between the stops made in it, and the diameter of the nozzle exceeds the maximum diameter of the head.
