Problems solved by technology

[0002] Existing passive automatic fire-fighting valve technologies, such as the passive automatic fire-fighting sprinkler valve with application number 201010156537.9, have been gradually accepted by the industry, and there is a development trend to replace glass bubble sprinklers! The basic principle is to use magnetic coupling technology to interact with shape memory alloys to realize self-operated opening and closing. However, the disadvantage of this invention is that the temperature control part and the valve body are connected together when they leave the factory, but the fire valve At the installation and construction site, since the workers cannot perform the installation process very carefully, the temperature control part will be separated from the valve body if they are not careful, or the working stroke will be changed, resulting in damage to the valve; another problem is that after the valve is installed, Impossible to test it with fire and high temperature to check whether the valve parameters are changed

Abstract

The invention discloses a split type fire valve, and belongs to the field of fire prevention automatic control devices. The split type fire valve is characterized in that a connecting bolt with a bolt cover is sleeved with temperature memory alloy and a thermal insulation mat; a temperature control head is connected with a screw hole in the upper portion of a linkage bolt at the upper end of a valve body though the connecting bolt after the valve body is correctly installed on site, and then on-site installation of the fire valve is completed.

Description

technical field [0001] The utility model relates to a sub-type fire valve, which belongs to the field of cooling and fire automatic control equipment. Background technique [0002] Existing passive automatic fire-fighting valve technologies, such as the passive automatic fire-fighting sprinkler valve with application number 201010156537.9, have been gradually accepted by the industry, and there is a development trend to replace glass bubble sprinklers!
