Technical Field

[0001] This utility model relates to the field of fire extinguishing system technology, and in particular to a test explosion device for the nozzle of an automatic sprinkler fire extinguishing system. Background Technology

[0002] A fire extinguishing system integrates dispersed fire extinguishing devices into a cohesive whole through physical connections or control logic. An automatic sprinkler head explosion test device is a specialized piece of equipment used to test the explosion performance of sprinkler heads in an automatic sprinkler system. Its main function is to verify whether the sprinkler head can reliably explode under specified pressure, temperature, and other operating conditions, ensuring that it can promptly activate its fire extinguishing function in the event of a fire. During the production, acceptance, or maintenance phases of the sprinkler head, by simulating the water pressure environment during an actual fire, the device tests whether the sprinkler head operates normally under design parameters, filters out unqualified products, and ensures the reliability of the automatic sprinkler system.

[0003] The current automatic sprinkler system nozzle test device still has some problems, the specific problems are as follows: When storing the device, due to the excessive length of the conduit, too much space is required for transportation and storage, which makes storage and transportation very difficult. Utility Model Content

[0004] The purpose of this invention is to provide a test device for the nozzles of an automatic sprinkler fire extinguishing system, in order to solve the problem that existing test devices for the nozzles of automatic sprinkler fire extinguishing systems are difficult to store.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic sprinkler head test device, including a housing; The tank is installed inside the outer shell, and a housing is installed at the top of one side of the outer shell, with a pressure valve installed at the top of the housing. The top of the outer shell is equipped with a conduit, and the top of the conduit is equipped with a flame arrester. The top of the flame arrester is equipped with a discharge pipe, and an outlet is installed on one side of the discharge pipe. The conduit has a folded structure at the middle position, and a connecting tube is installed at the bottom end of the conduit. Both the bottom and top ends of the connecting tube are equipped with baffles.

[0006] In use, the baffles at the top and bottom of the connecting tube first restrict the movement range of the rigid tube. When the rigid tube slides to the top, it will wrap around the flexible tube, which can fix the flexible tube, prevent the flexible tube from bending, and keep the tube straight. The rigid tube can slide to the bottom of the connecting tube, so that the connecting tube no longer covers the outside of the flexible tube. In this way, the flexible tube can be bent and folded, allowing the tube to bend for storage.

[0007] Furthermore, a storage structure is installed at one end of the outer shell, and the storage structure includes a door installed at one end of the outer shell. A latch is installed at one end of the door, and a latching groove is provided at one end of the outer shell. The storage structure allows the tank to be disassembled and assembled.

[0008] Furthermore, the inner diameter of the engaging groove is larger than the outer diameter of the engaging buckle, and the engaging groove and the engaging buckle constitute an engaging structure, which is easy to disassemble.

[0009] Furthermore, an anti-corrosion structure is installed on the outer side of the catheter, the anti-corrosion structure including a second anti-corrosion layer installed on the outer side of the catheter, and a first anti-corrosion layer installed on the inner side of the catheter. The anti-corrosion structure can enhance the anti-corrosion effect of the catheter.

[0010] Furthermore, an anti-corrosion coating is installed on the outer side of the second anti-corrosion layer. The inner diameter of the anti-corrosion coating is larger than the outer diameter of the second anti-corrosion layer. The anti-corrosion coating can enhance the anti-corrosion efficiency of the conduit.

[0011] Furthermore, a flexible tube is provided at the top of the connecting pipe, and a rigid tube is provided on the outside of the connecting pipe. The flexible tube can be folded and bent, while the rigid tube can fix the flexible tube.

[0012] Furthermore, the inner diameter of the rigid tube is larger than that of the connecting tube, and the rigid tube and the connecting tube form a sliding structure, allowing the rigid tube to slide on the outside of the connecting tube.

[0013] The automatic sprinkler head test device for fire extinguishing system provided by this utility model has the following advantages: during use, the conduit can be folded through the folding structure, which facilitates the storage and transportation of the device; the tank can be stored and disassembled through the storage structure; and the anti-corrosion structure can enhance the anti-corrosion effect of the conduit.

[0014] By installing a connecting pipe at the bottom of the conduit, the outer diameter of the connecting pipe being smaller than the inner diameter of the rigid pipe, the rigid pipe and the connecting pipe form a sliding structure. The rigid pipe can slide outside the connecting pipe. The baffles at the top and bottom of the connecting pipe can limit the range of movement of the rigid pipe. When the rigid pipe slides to the top, it will wrap around the flexible hose, which can fix the flexible hose, prevent the flexible hose from bending, and keep the conduit straight. The rigid pipe can slide to the bottom of the connecting pipe, so that the connecting pipe no longer covers the outside of the flexible hose. In this way, the flexible hose can be bent and the conduit can be folded, making the conduit flexible for carrying. This achieves the purpose of making the automatic sprinkler head test device more portable.

[0015] A door is installed at one end of the outer casing. The door can be rotated to open or close. The latch and latching groove at one end of the door form a latching structure, which facilitates the opening and closing of the door. When needed, the door can be closed by locking the latch into the latching groove. When the tank inside the outer casing needs to be processed, the door can be opened to carry out maintenance or processing inside the outer casing. This achieves the purpose of facilitating maintenance of the internal structure of the automatic sprinkler system. Attached Figure Description

The flame arrester 8 is a safety device used to prevent flame backfire from returning to the gas cylinder through the gas pipe. The flame arrester 8 has a large number of tiny channels or slit structures inside. When the flame enters, it will be divided into countless tiny flame streams by these structures. The surface area of ​​the tiny flame streams increases significantly, and the heat will be quickly conducted away through the metal or ceramic wall of the flame arrester 8, causing the flame temperature to drop rapidly. When the flame temperature drops below the "ignition point" of the combustible material, the combustion reaction can no longer be maintained, and the flame will be completely extinguished, thus preventing its further spread.
