The invention relates to street vacuum cleaners, and more particularly to valves for switching the inlet flows in a small vacuuming machine. The present inlet flow switching valve comprises a housing with openings. Said housing is configured in the form of a hollow triangular prism having two square walls and two triangular walls. The prism does not have a base. Said openings are configured in the square walls, which are arranged at an angle of 90 degrees to one another. Secured about the perimeter of the openings are nozzles for attaching hoses. Provided about the perimeter of the prism are flanges for attachment to the housing of a small vacuuming machine. Provided at the apexes of the triangular walls of the prism are holes for fastening a pivot pin of a closure flap. Provided outside the prism, at one end of said pivot pin, is a lever for allowing movement of the closure flap. Said lever is connected to the pivot pin, to which the closure flap is fastened by screws. The closure flap is fixable in two terminal positions. This makes it possible to switch the operating mode of a small vacuuming machine from a short pipe to a hose and back when collecting waste with a short pipe in tight spaces.
Description
КЛАПАН ПЕРЕКЛЮЧЕНИЯ ВХОДНЫХ ПОТОКОВ МАЛОЙ ВАКУУМНОЙ МАШИНЫ VALVE FOR SWITCHING INPUT FLOW OF A SMALL VACUUM MACHINE
Описание изобретения. Description of the invention.
Заявленное изобретение относится к приспособлениям для малых вакуумных машин (уличных пылесосов), а именно к клапанам переключения входных потоков малой вакуумной машины [A47L 9/02, Е01Н 1/00]. The claimed invention relates to devices for small vacuum machines (street vacuum cleaners), namely to valves for switching the input flows of a small vacuum machine [A47L 9/02, E01H 1/00].
Заявленный клапан предназначен для малых вакуумных машин (далее МВМ), также называемых «садовыми пылесосами» и тем самым предназначен расширить сферу применения до использования в ЖКХ. The claimed valve is intended for small vacuum machines (hereinafter referred to as MVM), also called “garden vacuum cleaners” and is thereby intended to expand the scope of application to use in housing and communal services.
На мировом рынке представлены модели МВМ предназначенные для уборки садов и парков с определенными функциями сбора мусора. Сбор осуществляется любо расширенным раструбом- соплом, либо шлангом. Для переключения из одного режима работы в другой требуется установить (снять) заглушку на раструбе практически у самой земли, что не имеет значения при переключении на длительное время. Однако, когда требуется периодически переключать с раструба на шланг в течении короткого промежутка времени, данная процедура в течение рабочего дня потребует значительных трудозатрат оператора. Клапан переключения входных потоков позволяет быстро и без усилий переключить работу машины с раструба на шланг и обратно. Данная функция требуется когда невозможно собрать мусор раструбом в узких местах, куда машина не сможет заехать (между припаркованными автомобилями, собрать мусор из мусорниц и т.п.). There are MVM models on the world market designed for cleaning gardens and parks with certain waste collection functions. Collection is carried out using either an extended socket-nozzle or a hose. To switch from one operating mode to another, you need to install (remove) a plug on the socket almost close to the ground, which does not matter when switching for a long time. However, when it is necessary to periodically switch from flare to hose over a short period of time, this procedure will require significant operator labor during the working day. The input flow switching valve allows you to quickly and effortlessly switch the operation of the machine from socket to hose and back. This function is required when it is impossible to collect garbage with a spout in narrow places where the car cannot enter (between parked cars, collecting garbage from trash cans, etc.).

Осуществление изобретения. Implementation of the invention.
Заявленный клапан переключения входных потоков (КПВП) 2 малой вакуумной машины (МВМ) 1 содержит корпус 3, выполненный в виде полой треугольной призмы, которая содержит две прямоугольные стенки и две треугольные стенки, основание призмы отсутствует. На прямоугольных стенках корпуса 1, которые расположены под углом 90 градусов друг к другу, выполнены отверстия 5, по
периметру которых закреплены патрубки 4 для подключения шлангов 13. На патрубки 4 надеваются шланги и закрепляются хомутами. По периметру основания призмы выполнены отгибы 9 для крепления к корпусу МВМ. В вершинах треугольных стенок призмы выполнены отверстия 9 для крепления оси заслонки. При этом с одной стороны оси снаружи призмы выполнен рычаг 8 для осуществления возможности перемещения заслонки 7. Рычаг 8 соединен с осью на которую винтами крепится заслонка. Заслонка 7 фиксируется в двух крайних положениях и может фиксироваться несколькими способами - пружиной, грузом на рычаге или магнитом. Заслонка 7 выполнена с возможностью переключения в рабочем состоянии. КПВП 2 устанавливается на входном фланце вентилятора 11 посредством резьбового соединения. Корпус изготовлен из листовой стали толщиной 1.0 мм. The claimed input flow switching valve (KPVS) 2 of a small vacuum machine (VVM) 1 contains a housing 3 made in the form of a hollow triangular prism, which contains two rectangular walls and two triangular walls; the base of the prism is absent. On the rectangular walls of the housing 1, which are located at an angle of 90 degrees to each other, holes 5 are made, around the perimeter of which pipes 4 are fixed for connecting hoses 13. Hoses are put on pipes 4 and secured with clamps. Along the perimeter of the base of the prism there are bends 9 for attachment to the MVM body. At the vertices of the triangular walls of the prism there are holes 9 for fastening the damper axis. In this case, on one side of the axis outside the prism there is a lever 8 to allow movement of the damper 7. Lever 8 is connected to the axis on which the damper is attached with screws. The damper 7 is fixed in two extreme positions and can be fixed in several ways - with a spring, a weight on a lever or a magnet. The damper 7 is designed to be switchable in operating condition. KPVP 2 is installed on the inlet flange of fan 11 via a threaded connection. The housing is made of 1.0 mm thick sheet steel.
Технический результат достигается тем, что конструкция заявленного клапана позволяет переключать входные потоки быстро и без усилий и тем самым переключить работу машины с раструба на шланг и обратно для реализации возможности собрать мусор раструбом в узких местах, куда машина не сможет заехать (между припаркованными автомобилями, собрать мусор из мусорниц и т. и.). Это осуществляется за счет того, что конструкция клапана простая и надежная - заслонка выполнена с возможностью переключения между двумя положениями за счет чего поток воздуха оперативно направляется из одного отверстия, расположенного на прямоугольной стенке корпуса в другое отверстие, расположенное на второй прямоугольной стенке под углом 90 градусов к первой, переключением заслонки с помощью рычага. За счет того, что корпус выполнен в виде полой треугольной призмы, которая содержит две прямоугольные стенки и две треугольные стенки, основание призмы отсутствует, по периметру основания призмы выполнены отгибы для крепления, а по периметру отверстий закреплены патрубки для подключения шлангов, обеспечивается возможность установить клапан вместо всасывающего патрубка на центробежном вентиляторе МВМ и эффективно перенаправлять поток воздуха за счет
переключения заслонки посредством того, что в вершинах треугольных стенок призмы выполнены отверстия для крепления оси шторки, при этом с одной стороны оси снаружи призмы выполнен рычаг для осуществления возможности перемещения заслонки, при этом рычаг соединен с осью на которую винтами крепится заслонка, заслонка фиксируется в двух крайних положениях.
The technical result is achieved by the fact that the design of the claimed valve allows you to switch input flows quickly and effortlessly and thereby switch the operation of the machine from a socket to a hose and back to realize the possibility of collecting garbage with a socket in narrow places where the machine cannot enter (between parked cars, collecting garbage from garbage cans, etc.). This is due to the fact that the design of the valve is simple and reliable - the damper is designed to switch between two positions, due to which the air flow is quickly directed from one hole located on the rectangular wall of the housing to another hole located on the second rectangular wall at an angle of 90 degrees to the first, by switching the damper using a lever. Due to the fact that the body is made in the form of a hollow triangular prism, which contains two rectangular walls and two triangular walls, there is no base of the prism, bends for fastening are made along the perimeter of the base of the prism, and pipes for connecting hoses are fixed around the perimeter of the holes, it is possible to install a valve instead of the suction pipe on the MVM centrifugal fan and effectively redirect the air flow due to switching the damper due to the fact that in the vertices of the triangular walls of the prism there are holes for fastening the shutter axis, while on one side of the axis outside the prism there is a lever to make it possible to move the shutter, while the lever is connected to the axis on which the shutter is attached with screws, the shutter is fixed in two extreme positions.
