Description

Technical Field

[0001] The invention relates to the field of sprinkler heads, and more particularly to a fire sprinkler head installation structure which is convenient to install. Background Art

[0002] A fire sprinkler is a type of sprinkler that automatically starts up within a predetermined temperature range under the action of heat, or is started up by a control device based on a fire signal, and sprays water to extinguish fires in a designed spraying shape and flow rate. A glass ball sprinkler is a common type of fire sprinkler, and its heat-sensitive element is a glass ball. When the sprinkler is heated, the working fluid in the glass ball takes effect, causing the ball to burst and open. For existing sprinkler heads, after the glass ball breaks, it is always in a spraying state. After the fire is extinguished at the corresponding part, the main water supply pipe needs to be closed to stop the water supply. However, this operation will cause the water supply of the entire fire sprinkler system to stop, and there will be fire hazards in other parts. If the water is not turned off, the corresponding part will be in a state of continuous leakage, causing waste. Summary of the invention
