Embodiment 1

[0032] A surface-mounted hydraulic alarm device embedded in the wall, which consists of a sound reflector embedded in the wall, a hydraulic alarm bell and two pipe fittings. The sound reflector is a hemispherical stainless steel concave surface with a diameter 200 mm larger than the hydraulic alarm bell. There are two through holes matching the pipe fittings on the arc surface wall. The hydraulic alarm bell is located in the middle of the concave space of the sound reflector. The two pipe fittings are respectively connected to the water inlet pipe and outlet pipe of the hydraulic alarm bell. The outlet pipe and the water inlet pipe of the fire-fighting water pipe are connected through the through hole.

[0033] The installation method of the surface-mounted hydraulic alarm device embedded in the wall in this embodiment: (1) Installation of the sound reflector: According to the characteristics of the hemispherical shape of the sound reflector, a hole matching the size of the sou...

Embodiment 2

[0035] A wall-embedded surface-mounted hydraulic alarm device, which is composed of a sound reflector embedded in the wall, a hydraulic alarm bell and two pipe fittings. 250 mm in diameter, two through holes matching the pipe fittings are provided on the arc surface wall, the hydraulic alarm bell is set in the middle of the concave space of the sound reflector, and the two pipe fittings are respectively connected to the hydraulic alarm bell water inlet pipe and the water outlet pipe, The other end of the pipe fitting passes through the through hole to communicate with the water outlet pipe and the water inlet pipe of the fire water pipe respectively.

[0036] The installation method of the surface-mounted hydraulic alarm device embedded in the wall of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0038] A surface-mounted hydraulic alarm device embedded in the wall, which is composed of a sound reflector embedded in the wall, a hydraulic alarm bell and two pipe fittings. The sound reflector is a semi-ellipsoid copper material concave surface, and its diameter is larger than that of the hydraulic alarm bell. 300 mm, and two through holes matching the pipe fittings are provided on the arc surface wall. The hydraulic alarm bell is set in the middle of the concave space of the sound reflector, and the two pipe fittings are respectively connected to the water inlet pipe and the outlet pipe of the hydraulic alarm bell. The other end passes through the through hole to communicate with the water outlet pipe and the water inlet pipe of the fire water pipe respectively.

[0039] The installation method of the surface-mounted hydraulic alarm device embedded in the wall of this embodiment is the same as that of Embodiment 1.

Description

technical field [0001] The invention belongs to the field of building fire-fighting equipment, and specifically relates to a wall embedded surface-mounted hydraulic alarm device and an installation method thereof, which is suitable for the design and installation of hydraulic alarm bells outside fire pump rooms of various buildings, and is especially suitable for building drainage systems. Design and installation of alarm bells. Background technique [0002] The hydraulic alarm bell is a sounding alarm device driven by water flow, and is usually used as an auxiliary device for the alarm valve of the automatic sprinkler system. When any sprinkler head of the automatic sprinkler system operates or the test valve is opened, the system alarm valve will automatically open, and a continuous alarm sound will be issued to inform the personnel on duty that a fire has occurred. [0003] At present, the hydraulic alarm bells are usually concentrated and mounted on the wall of the corr...
