The self-extinguishing device is characterized in that a three-way valve is installed at one end of the fire detecting tube exposed outside the protected area; two ways of the three-way valve are respectively connected with the fire detecting tube positioned at two ends, and the other way is connected with a pressure warning unit through an inlet pipeline; the pressure warning unit comprises a pressure gauge, a pressure switch, a sound alarming module and a remote warning signal interface module; the inlet pipeline of the pressure warning unit is sequentially communicated with the pressure gauge and an input end of the pressure switch; and an output end of the pressure switch is respectively connected with the sound alarming module and the remote warning signal interface module.

Description

A kind of spy fire tube automatic fire extinguisher

Technical field

The utility model relates to the technical field of structures of local extinguishing device, is specially a kind of spy fire tube automatic fire extinguisher.

Background technology

The bottle valve structure of existing spy fire tube automatic fire extinguisher; see Fig. 1; it comprises extinguishing chemical storage bottle 1; bottle valve 2; bulb valve 3; visit fire tube 4; Pressure gauge 5; an end of visiting fire tube 4 connects bulb valve 3; another blind end of visiting fire tube 4 connects Pressure gauge 5; wherein the fire tube internal pressure is visited in Pressure gauge 5 indications; when breaking out of fire; visit fire tube and break 4; and then Pressure gauge 5 number of degrees diminish; visit fire tube automatic fire extinguisher work fire extinguishing then; though visit fire tube automatic fire extinguisher energy operate as normal; but, Pressure gauge can find that just protected device fire occurred or fire just occurred because needing the staff to go to observe; when so even fire takes place; the staff still can not accurately grasp the state of protected device of the very first time intuitively, gives the replacing of follow up device; maintenance has brought time-lag, finally causes device can't run well under the situation of needs running.

Summary of the invention

At the problems referred to above, the utility model provides a kind of spy fire tube automatic fire extinguisher, its fire can feed back to the staff in time, rapidly when taking place, and also allows the staff in time finish replacing, maintenance to device, guarantees that device runs well under the situation of needs running.

A kind of spy fire tube automatic fire extinguisher; its technical scheme is such: it comprises the extinguishing chemical storage bottle; bottle valve; visit fire tube; the protected area; described spy fire tube is arranged in described protected area; it is characterized in that: the end that described spy fire tube exposes to described protected area is equipped with threeway; wherein two reduction of fractions to a common denominators of described threeway do not connect the spy fire tube at two ends; another is crossed inlet ductwork all and connects pressure alarm; described pressure alarm comprises Pressure gauge; pressure switch; the audible alarm module; the remote alarms Signal interface module; the described inlet ductwork of described pressure alarm is communicated with described Pressure gauge successively; pressure switch input, the output of described pressure switch connect described audible alarm module respectively; the remote alarms Signal interface module.

It is further characterized in that: the described audible alarm module of described pressure warning unit is connected with test button.

After adopting structure of the present utility model, when system normally moved, alarm connects visited fire tube, and the high-pressure inert gas of visiting in the fire tube is introduced into Pressure gauge, enters pressure switch again, and this moment, pressure switch was in poised state; Visit fire tube since catch fire or temperature too high molten when broken, pressure switch loses pressure, inwardly output signal to the audible alarm module, the audible alarm module is sent the sound of warning, outwards output signal to the remote alarms Signal interface module, the remote alarms Signal interface module provides signal can for other monitoring system, and its fire can feed back to the staff in time, rapidly when taking place, also allow the staff in time finish replacing, maintenance, guarantee that device runs well under the situation of needs runnings device.
