Gravity change-over switch for boiler

一种用于锅炉的重力转换开关

Abstract

本实用新型公开了一种用于锅炉的重力转换开关,具体包括转换腔体,转换腔体外部设有三个烟气通道,分别为副烟道、主烟道和烟气出口,在转换腔体设有可以转动的翻板,翻板封闭副烟道或主烟道,保证副烟道或主烟道与烟气出口连通,在翻板的一侧设有配重,配重的重量大于翻板的重量,并且配重和翻板的重心处于翻板一侧。本实用新型通过配重的重量以及风机吹动烟气流动,实现锅炉排烟通道之间的转换,避免人工操作,满足数控锅炉的自动化采暖。
The utility model discloses a gravity change-over switch for a boiler. The gravity change-over switch particularly comprises a change-over cavity. Three flue gas channels are arranged outside the change-over cavity and are the auxiliary flue, the main flue and the flue gas outlet. The change-over cavity is provided with a turning plate capable of rotating. The turning plate seals the auxiliary flue or the main flue, it is guaranteed that the auxiliary flue or the main flue is communicated with the flue gas outlet, one side of the turning plate is provided with a balance weight, the weight of the balance weight is larger than the weight of the turning plate, and the gravity of the balance weight and the gravity of the turning plate are located on one side of the turning plate. According to the gravity change-over switch, flue gas is blown by a fan under the weight action of the balance weight to flow, change-over among exhaust flues of the boiler is achieved, manual operation is avoided, and the requirement for automated heating of the numerical control boiler is met.
