Embodiment Construction

[0110] The present invention will be further described below in conjunction with the accompanying drawings.

[0111] like Figure 1-6 Shown, a kind of prediction model of the response time of the present invention predicts closed sprinkler head or temperature-sensitive detector, comprises the following steps:

[0112] Step 1. Basic assumptions

[0113] The closed nozzle of the automatic sprinkler system has the dual functions of temperature detection and water distribution to extinguish fire. The prediction method of the temperature detector is the same as the response time prediction method of the closed sprinkler. The predictive model that the present invention establishes is based on following 3 basic assumptions:

[0114] (1) The nozzle or temperature detector is located in a large space and installed under a flat ceiling according to relevant specifications. The high ceiling means that as the flame rises it brings in more surrounding air, which cools the gas. Beams, b...

Abstract

The invention relates to a prediction model for predicting response time of a closed type sprinkler head or a heat detector, belonging to the technical field of fire fighting. The prediction model comprises steps of basic assumption, basic model principle setting, fire hazard design, response time prediction and the like. The prediction model is established for the response time of the sprinkler head or the heat detector in different fire hazard situations, technical means are provided for evacuation start time prediction and fire hazard scale prediction for fireproof design of a building, the response time of the closed type sprinkler head or the heat detector in fire hazard situations can be predicted, the prediction model is applicable to different types of fire hazard, the nationalization of the prediction model is achieved, software which is designed according to the model principle can be operated on a Chinese WIDOWS interface, and the usability and the comparison accuracy of a prediction model tool can be achieved.

Description

technical field [0001] The invention relates to a prediction model, in particular to a prediction model for predicting the response time of a closed sprinkler head or a temperature-sensitive detector, and belongs to the technical field of fire protection. Background technique [0002] The automatic sprinkler system has a history of more than 100 years since its birth, and it has played an important role in protecting people's lives and property safety in fires. The purpose of setting up the automatic sprinkler system is mainly to effectively extinguish the initial fire or control the scale of the fire. For an automatic sprinkler system with a closed sprinkler head, in order to quickly start fire control and extinguish the fire, whether the sprinkler head can act in time is an important factor, which is crucial to the fire extinguishing and fire control effect of the entire sprinkler system. If the closed sprinkler head cannot be heated and opened in time, the sprinkling wat...
