Abstract
The utility model relates to an alarm device for providing audible and visual indication signal. The inner side of the flange cover of a casing is provided with a short butterfly plate and a long butterfly plate, and the casing of the lower part of the long butterfly plate is provided with a proximity switch SW1 which can be connected to a circuit connecting plate which is arranged in a box body. The circuit connecting plate can be provided and connected witha relay K, a buzzer B, a red signal lamp LY and a green signal lamp LG. The utility model can make pipeline transportation safety, and the alarm sound signal and display signal can be simultaneously emitted when cut-out phenomenon appears. The utility model has the advantages of high sensitivity, small size, simple and compact structure, simple circuit, few elements, low cost, etc.
Description
The utility model relates to providing can listen and visible signalling warning device of indicating particularly a kind of pipeline butterfly plate formula cutout warning device.
Commercial production piped water supply at present, fuel feeding, strict requirement is arranged during conveyings such as air feed, piped water supply, fuel feeding, people mostly are by flow instrument during conveyings such as air feed, manometer or human eye are directly observed, ubiquity piped water supply, fuel feeding, observation difficulty when air feed etc. are carried, thereby be difficult to satisfy on-the-spot requirement, safe and reliable water supply, fuel feeding, the air feed effect is undesirable, waste time and energy, when the cutout phenomenon occurring, take measures easily to cause when untimely and stop production and equipment brought shortcomings such as a serious destructive accident and a row economic loss, in order to overcome above-mentioned weak point, the utility model has designed a kind of pipeline butterfly plate formula cutout warning device.
The purpose of this utility model provides a kind of energy and satisfies on-the-spot requirement, can make piped water supply, fuel feeding, air feed delivery safety reliable, when the cutout phenomenon occurring, can send alarm sound signal and shows signal simultaneously, highly sensitive, can prevent to avoid causing stopping production and, observe time saving and energy saving butterfly plate formula cutout warning device the generation that equipment brings a serious destructive accident and a row economic loss.
The utility model is achieved in that the shape of housing is three-way shape, one flange disk cover is arranged on the top of housing, two identical supporting plates before and after on the medial surface of flange disk cover, having, tool through hole on supporting plate, in two stands plate through hole, a support shaft is installed, be welded with the short butterfly plate of a semicircle counterweight at the upside of support shaft, be welded with an oval-shaped long butterfly plate, on housing below the long butterfly plate, connect and be equipped with one near switch SW at the downside of support shaft
