Description
(5) УСТРОЙСТВО ДЛЯ РЕГУЛИРОВАНИЯ РАСХОДА (5) DEVICE FOR REGULATING CONSUMPTION
II
Изобретение относитс к области вентил ции и может быть применено в воздухозаборных устройствах систем приточной вентил ции.The invention relates to the field of ventilation and can be applied in the intake devices of the intake ventilation systems.
. Известно устройство дл регулировани расхода воздуха, содержащее корпус с поворотной створкой установленной на полуос х, смещённых относительно ее центра т жести, и снабженной противовесом и ограничителем поворота 1 .. A device for controlling the flow of air is known, comprising a housing with a rotary flap mounted on semi-axes displaced relative to its center of gravity, and provided with a counterweight and a rotation stop 1.
Недостатком известного устройства вл етс низкое качество perjlfлировани из-за отсутстви возможности обеспечени регулировани производительности вентил тора при его налаживании.A disadvantage of the known device is the poor quality of perjlfi due to the lack of the possibility of controlling the performance of the fan when it is adjusted.
Цель изобретени - повышение качества регулировани .The purpose of the invention is to improve the quality of regulation.
Поставленна цель достигаетс тем, что в створке выполнен направл ющие пазы, в которых установлен с возможностью перемещени упом нутый противовес. ВОЗДУХАThis goal is achieved by the fact that the sash has guide grooves in which said counterweight is mounted for movement. AIR
На фиг.1 показано устройство дл регулировани расхода воздуха, общий вид; на (lwr.2 - вид А на фиг.1. Устройство дл регулировани расхода воздуха содержит корпус 1 с поворотной створкой 2, установленной на полуос х 3, смещенных относите.пьно ее:центра т жести, и снабженной противовесом Ц и ограничителем 5 поворота, в створке 2 выполнены направл ющие пазы 6, в кэторых установлен с возможностью перемещени упом нутый противовес ЛУстройство работает следующим образом.Figure 1 shows a device for controlling the flow of air, a general view; on (lwr.2 - view A in Fig. 1. The device for controlling the flow of air comprises a housing 1 with a rotary flap 2 mounted on a semi-axis x 3 displaced with respect to it: the center of gravity and equipped with a counterweight C and a rotation stop 5 , in the flap 2, the guide grooves 6 are made; in these, the mentioned counterweight is mounted for movement in the following manner.
При включении вентил тора (не показан ) створка 2 из-за образующегос вакуума в приточной камере поднимаетс , при выключении вентил тора опускаетс . Величина открыти створки 2 регулируетс противовесом k, который может перемещатьс по направл ющим пазам 6 к полуоси 3 створки 2.When the fan (not shown) is turned on, the flap 2 rises due to the generated vacuum in the inlet chamber, and when the fan is turned off, it lowers. The magnitude of the opening of the flap 2 is adjusted by the counterweight k, which can move along guide grooves 6 to the half-axis 3 of the flap 2.
