Description

Fire-fighting spray head

Technical Field

The utility model relates to a fire sprinkler system field, in particular to fire sprinkler head.

Background

Along with the high-speed development of society, people's fire control safety consciousness is higher and higher, in order to reduce the loss that the conflagration caused, people set up various fire fighting tools in various buildings in advance, such as fire hydrant, smoke alarm, fire sprinkler head, fire extinguisher, fire fighting tool.

The existing fire sprinkler head has some disadvantages: firstly, the outlet of the pipeline is sealed by a glass body, and the glass body can be broken during construction or accidental contact, so that indoor water inflow and property loss are caused; secondly, when a fire disaster occurs under the unmanned condition, the fire-fighting nozzle cannot be automatically closed after extinguishing a fire source, so that water source waste, indoor water inflow and property loss are caused, the main gate needs to be closed under the manned condition, a professional person needs to replace the glass body to adjust the pretightening force of the glass body, and water cannot be sprayed if a fire disaster occurs in other areas in the waiting process; finally, the glass body is a disposable product, and the stability of the glass body cannot be detected by 100 percent, and the glass body can be similar to a dummy glass body if the quality is abnormal.

Disclosure of Invention

An object of the utility model is to provide a fire sprinkler head can effectively solve the defect that exists among the above-mentioned background art:

in order to achieve the above purpose, the utility model adopts the following technical scheme:

the fire-fighting spray header comprises a main body, wherein a water splashing disc is fixedly mounted above the main body, an inner cavity at the upper end of the main body is fixedly mounted with a temperature control valve core, a piston rod is mounted in the inner cavity of the main body, a sealing ring is mounted on the piston rod, a compression spring is mounted below the piston rod, a support is fixedly mounted in the inner cavity of the main body, the support is attached to the other end of the compression spring, and a small hole is formed in the center of the support.

Preferably, the main body and the temperature control valve core are in threaded connection.

Preferably, the piston rod and the sealing ring seal the internal passage of the main body.

Preferably, the support adopts square shape, and the center is punched and is fixedly connected with the main body in a stamping or thread mode.

Preferably, the piston rod passes through a central small hole of the bracket.

Compared with the prior art, the utility model discloses following beneficial effect has: firstly, a temperature control valve core made of copper alloy is adopted in the fire-fighting nozzle, so that water leakage cannot be caused in the decoration process or accidental touch; secondly, when a fire disaster occurs, the temperature rises, the temperature control valve core opens the main body channel by pushing the piston rod open, and when the temperature drops after the fire disaster is extinguished, the temperature control valve core contracts to automatically close the channel; finally, the temperature control valve core can be tested by 100% after being installed, and the use process is guaranteed to be completely lost.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is an exploded view of the fire spray head of the present invention.

Reference numbers in the figures: the water splashing device comprises a main body 1, a water splashing disc 2, a temperature control valve core 3, an ejector rod 3-1, a sealing ring 4, a piston rod 5, a compression spring 6, a support 7 and a support 7-1, wherein a central small hole is formed in the support 7.

Detailed Description

The technical solutions in the embodiments of the present invention are clear and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without any creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, the utility model provides a fire sprinkler head technical scheme: the temperature-sensing water heater comprises a main body 1, a water splashing disc 2 is fixedly mounted above the main body 1, an inner cavity at the upper end of the main body 1 is fixedly mounted with a temperature control valve core 3, a piston rod 5 is mounted in the inner cavity of the main body 1, a sealing ring 4 is mounted on the piston rod 5, a compression spring 6 is mounted below the piston rod 5, a support 7 is fixedly connected with the inner cavity of the main body 1 and is attached to the other end of the compression spring 6, and a small hole 7-.

The main body 1 and the temperature control valve core 3 are connected by screw threads.

The piston rod 5 and the sealing ring 4 seal the internal passage of the body.

The support 7 is square, is provided with a hole 7-1 in the center and is fixedly connected with the main body 1 in a stamping or thread mode.

The piston rod 5 passes through a central small hole 7-1 of the bracket 7.

The working principle is as follows:

when a fire disaster occurs, the indoor temperature continuously rises, when the temperature control valve core 3 senses the external high temperature, the internal thermosensitive material of the temperature control valve core 3 expands, the ejector rod 3-1 extends downwards to push the piston rod 5, the spring 6 is continuously compressed, then the outlet is opened, the water of the fire fighting pipeline is sprayed out, and the fire source is extinguished by dispersing the water through the water splashing disc.

When the fire is extinguished, the indoor temperature is gradually reduced, and the temperature control valve core 3 senses the external low temperature, the internal thermosensitive material shrinks, the thrust of the ejector rod 3-1 is reduced, and the spring 6 releases the elastic force and closes the outlet of the pipeline at the same time.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
