Problems solved by technology

However, due to the limitation of its plugging form, most of these fire extinguishing devices are disposable products. Once the device leaks, the device can only be removed from the plugging end cap, and then the fire extinguishing agent canned and heat-welded or crimped. Time-consuming
In addition, such flexible fire extinguishing devices on the market usually judge whether there is leakage in the device by observing the readings of the pressure transmitter or pressure display. However, due to the large size of the pressure transmitter or pressure display, it not only affects the overall aesthetics, It also affects the ease of installation of the device

Embodiment 1

[0017] Such as figure 1 , 2 , A flexible temperature-sensitive self-starting fire extinguishing device that can be conveniently filled and leak-detected as shown in 3 and 4 includes a flexible pipe section 2, a leak detection device connected to one end of the flexible pipe section 2, and a flexible pipe section 2 The other end of the Filling device 3.

[0018] In this embodiment, the leak detection device includes a plugging end cap 1, an elastic element 12 is installed inside the plugging cap, a piston element 14 is installed at the bottom, and a sealing ring 13 is arranged between the piston element 14 and the pipe wall, and the sealing ring passes through the The outer wall of the piston element is sealed with the inner wall of the flexible pipe section so as to realize the sealing of the fire extinguishing agent of the flexible pipe section. The outer end of the piston element 14 is provided with a connecting rod 15, and the outer end of the connecting rod 15 is provided...

Embodiment 2

[0022] Such as Figure 5 As shown, the threaded interface 352 at the front of the filling device 3 is connected with a remote alarm device 4, and the remote alarm device 4 is screwed downwards into the top-opening valve core thimble 351 through threads. 44. At this time, the sealing ring 44 acts as a seal on the end face to prevent leakage of the fire extinguishing agent in the fire extinguishing pipe, and the remote alarm device 4 enters the quasi-working mode. The sealing method here is not limited to relying on the end face extrusion seal, and the radial seal ring is used The same method applies. When there is leakage in the fire extinguishing pipe and the pressure in the pipe decreases below the alarm critical point of the remote alarm device, the remote alarm device 4 will perform a remote alarm.

[0023] The present invention follows the working principle of the traditional fire detection tube fire extinguishing device, and releases the fire extinguishing agent when the...

Abstract

The flexible temperature-sensing self-starting fire extinguishing device comprises a flexible pipe section, a leakage detecting device and a filling device, the leakage detecting device comprises a plugging end cover, an elastic element is installed in the plugging cover, a piston element is installed at the bottom of the plugging cover, and a sealing ring is arranged between the piston element and the pipe wall; the sealing ring seals the fire extinguishing agent of the flexible pipe section by sealing the outer wall of the piston element and the inner wall of the flexible pipe section, a connecting rod is arranged at the outer end of the piston element, a pressure cap is arranged at the outer end of the connecting rod, and the connecting rod is connected into a penetrating hole in the middle of the plugging end cover in a penetrating mode. According to the invention, the efficiency and convenience of equipment filling work are effectively improved, and effective leak detection can be realized.

Description

technical field [0001] The invention relates to the field of fire extinguishing devices, in particular to a flexible temperature-sensing self-starting fire extinguishing device that can be conveniently filled and leak detected. Background technique [0002] The use of fire extinguishing devices is becoming more and more popular in today's social life and industrial production. At present, for small space, relatively closed and sporadic, independent protection objects, such as small power distribution cabinets and small control cabinets, fire detection tube fire extinguishing devices or flexible fire extinguishing devices are mainly used on the market for protection. The fire detection tube fire extinguishing device is still not economical because it needs a special container to store the fire extinguishing agent, and there are additional requirements for the place in the installation. The flexible fire extinguishing device fills the fire extinguishing agent inside through a...
