Abstract

The invention discloses a sealing performance detection device for a fire-fighting spray head. The sealing performance detection device comprises a support, a screw rod elevator, a piston cylinder, aspraying head positioning plate and air cylinders, wherein the piston cylinder is fixed in the support, a piston is arranged in the piston cylinder, the top of the piston cylinder is provided with a water outlet port which can be in butt joint with a joint of a fire-fighting spray head to be detected, and a water inlet pipe used for injecting water into the piston cylinder is further arranged on the piston cylinder; the screw rod elevator is fixed in the support, and the top end of the lifting screw rod of the screw rod elevator is fixedly connected with the piston; and the fire-fighting sprayhead to be detected is fixed in the spray head positioning plate, a plurality of cylinder bodies of the air cylinders are fixed on the support, and the spray head positioning plate is fixedly connected with push rods of the air cylinders. The sealing performance detection device is small in water consumption, the pressure is adjustable in the detection process, the pressurization speed is high, the detection speed is high, and the efficiency is high.

Description

technical field [0001] The invention relates to a fire-fighting sprinkler head, in particular to a sealing performance detection device for a fire-fighting sprinkler head. Background technique [0002] figure 1 It is a schematic diagram of a fire sprinkler head, and the interface 101 of the fire sprinkler head 100 is generally connected with a fire water pipeline. Under normal temperature conditions, the fire sprinkler head 100 is in a sealed state, and the water in the pipeline will not leak from the fire sprinkler head 100 . Only when the temperature is higher than normal, the glass sphere of the fire sprinkler head 100 is broken, the seal loses its support and is washed away, and the water flow in the pipeline is sprayed upward, downward or sideways to the splash plate of different designs, thereby To achieve the purpose of automatic sprinkler fire extinguishing. [0003] Therefore, when the fire sprinkler head leaves the factory, the qualified fire sprinkler head has ...
