The outer end of the splash pan is of a rectangular tooth structure, so that the water distribution performance can satisfy the new national standard requirements.

Description

A special response glass bulb sprinkler head for fire fighting

technical field

The utility model relates to a glass ball sprinkler head of an automatic fire sprinkler system, in particular to a special response glass ball sprinkler head for fire extinguishing.

Background technique

The glass bulb sprinkler is a product used for fire extinguishing. The structure of the glass bulb sprinkler in the prior art includes: a sprinkler body, a glass ball, a sealing seat and a spring pad; a splash plate is installed on the upper part of the sprinkler body; Fastening screws are installed in the inner threaded holes in the upper part; the lower part of the nozzle body is a pipe joint, which is connected to the water pipe; a spring pad is provided on the upper end of the inner hole of the pipe joint, and the hole in the spring pad supports the sealing seat. A glass ball is arranged between the sealing seat and the fastening screw.

The structure of the sealing seat in the prior art is: its exterior is a stepped cylinder, the lower part of the sealing seat 4 is a cylinder with a smaller diameter, and the cylindrical end of the lower part of the sealing seat 4 is inserted into the inner hole of the pipe joint 8; In the center is a blind hole terminating in a conical surface that supports the conical surface of the glass sphere on the circle where the conical surface intersects the blind hole.

The structure of the splash plate in the prior art is: the outer end of the splash plate is a fan-shaped tooth structure, and the bottoms of adjacent fan-shaped tooth roots are directly connected by a circle.

The above-mentioned prior art has the following defects: the sealing seat in the prior art glass bulb sprinkler head is a stepped cylinder outside, when the ambient temperature exceeds the set temperature, the glass bulb will automatically break, and the sealing seat and spring pad often fall into and get stuck. In the inner diameter of the pipe joint, it directly affects the water distribution effect of the water spray in the water pipe.

The prior art splash plate has the following defects: the water distribution performance of the glass ball sprinkler head cannot meet the requirements of the new national standard GB5135.1-2003, and the water distribution uniformity is very poor.

Contents of the invention

The purpose of this utility model is to overcome the deficiencies of the above-mentioned technologies, and to provide a kind of glass ball broken automatically when the ambient temperature exceeds the set temperature, the sealing seat and the spring pad are not stuck in the inner diameter of the pipe joint, and the water distribution is uniform. Special response glass bulb sprinklers for fire extinguishing.

The technical solution to solve the above technical problems is: a special response glass bulb sprinkler for fire extinguishing, the special response glass bulb sprinkler includes: a sprinkler body, a glass ball, a sealing seat and a spring pad; the upper part of the sprinkler body A splash plate is installed; fastening screws are installed in the inner threaded hole on the upper part of the nozzle body; the lower part of the nozzle body is a pipe joint connected to the water pipe; a spring pad is provided on the slit at the upper end of the inner hole of the pipe joint, and the spring pad supports the sealing seat. A glass ball is arranged between the sealing seat and the fastening screw, and the lower part of the sealing seat supported by the spring pad is inserted into the inner hole of the pipe joint, and the cylindrical end of the lower part of the sealing seat is provided with a cylinder end inclined to the center line of the sealing seat. inclined plane.

The beneficial effects of the utility model are: the cylindrical end of the lower part of the utility model is provided with a slope inclined to the center line of the seal seat. The sealing seat will not stay in the nozzle body when the new type sprays water. To ensure that the utility model sprays water evenly without blind spots.

Since the outer end of the splash plate on the upper part of the nozzle body is a rectangular tooth structure, and there is a transition fillet between the bottoms of adjacent tooth roots, the water distribution performance of the utility model can meet the requirements of the new national standard of GB5135.1-2003. Spray evenly when watering.
