Distributed point-by-point follow-up spray type temperature-control fire-fighting system with memory alloy spring

Abstract

The invention provides a distributed point-by-point follow-up spray type temperature-control fire-fighting system with a memory alloy spring and belongs to the field of temperature-control spray fire-fighting gridding technologies. The distributed point-by-point follow-up spray type temperature-control fire-fighting system is characterized by comprising a manual check valve for gridding concentrated compensation control, a parallel connection distributed type auxiliary spray fire-fighting valve group, a compression spring control type main spray fire-fighting valve and a connecting component based on a three-way pipe hoop, wherein the auxiliary spray fire-fighting valve group is controlled by the temperature of the memory alloy spring and used for point-to-point control, and the compression spring control type main spray fire-fighting valve is used for point-by-point follow-up spray. In the normal state, the check valve is closed manually, all auxiliary spray fire-fighting valves connected in parallel and the main spray fire-fighting valve are closed, when the ambient temperature of one or more auxiliary spray fire-fighting valves rises to the acting temperature of the memory alloy spring, the corresponding auxiliary spray valves are opened, the main spray fire-fighting valve is opened therewith, and spray is achieved; and if human intervention is needed, the check valve is opened manually, the other paths of auxiliary spray valves distributed in parallel still can perform the spray operation. The distributed point-by-point follow-up spray type temperature-control fire-fighting system achieves point-to-point point-by-point spray in large space, and manual spray can be performed when a failure happens.

Description

technical field [0001] The distributed point-by-point follow-up spray memory alloy spring temperature control fire protection system belongs to the temperature control fire protection system, and in particular relates to a temperature control spray fire protection valve temperature control spray fire grid technology field based on memory alloy springs. Background technique [0002] At present, the control mode of the temperature-controlled sprinkler fire valve based on memory alloy spring is point-to-point discrete, and there are the following problems: [0003] 1. Grid-based distributed control based on centralized control mode cannot be realized, which affects the control effect in a certain space, and cannot guarantee the timeliness of control, which is related to the narrow control field; [0004] 2. The reliability is poor. When the memory alloy spring fails, the corresponding monitoring point cannot perform timely and effective control when the monitored target reach...

AI Technical Summary

Problems solved by technology

[0003] 1. Grid-based distributed control based on centralized control mode cannot be realized, which affects the control effect in a certain space, and cannot guarantee the timeliness of control, which is related to the narrow control field;

[0004] 2. Poor reliability. When the memory alloy spring fails, the corresponding monitoring point cannot be controlled in a timely and effective manner when the monitored target reaches the temperature

[0005] 3. The point-to-point control makes the spray points scattered, and it is inconvenient to debug and control
