Glass ball water spraying sprayer

Abstract

The invention relates to the technical field of fire fighting equipment, and particularly discloses a glass ball water spraying sprayer. The glass ball water spraying sprayer comprises a sprayer body, a glass ball and a water splashing disc. An installing base is arranged on the sprayer body and provided with a first through hole, a second through hole and a third through hole. A sealing plug is arranged in the first through hole and comprises a first stop column and a second stop column. One part of the end portion of the second stop column is a plane, and the other part of the end portion of the second stop column is a bevel. The installing base and the water splashing disc are connected through two support rods. The glass ball is fixed between the water splashing disc and the sealing plug through a pre-tightening screw, and the connecting line of the two support rods is parallel to the intersection line of the plane and bevel of the end portion of the second stop column. The two ends of the glass ball are in a spherical surface shape. The end, making contact with the glass ball, of the pre-tightening screw is provided with a pit matched with the spherical surface of the glass ball. An arc buffering pad is arranged in the pit, and a counter bore is formed in the center position of the sealing plug and internally provided with a buffering ring. The glass ball water spraying sprayer has the beneficial effects that the glass ball cannot be expanded broken, and the water spraying track cannot be influenced.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a glass ball sprinkler head. Background technique [0002] Fire sprinkler refers to a sprinkler that starts automatically according to a predetermined temperature range under the action of heat, or is started by a control device according to a fire signal, and sprinkles water to extinguish fire according to the designed sprinkling shape and flow rate. The glass ball sprinkler is a common one. A fire sprinkler head, the thermal element of which is a glass ball, when the sprinkler head is heated, the working fluid in the glass ball acts to cause the ball to burst and open. The glass bulbs in the existing fire sprinkler head are all provided with a mounting hole on the dropable sealing plug, the protrusion at one end of the glass bulb is inserted into the mounting hole, and the other end is locked by a pre-tightening screw. In the process of tightening the screw to ...
