Automatic spray conduit system and installation method thereof

Abstract

The invention relates to an automatic spraying pipeline system, which can reduce the installation difficulty of the pipeline and independently carry out construction with an easy control over the construction, thus guaranteeing the construction period of the system and the installation quality of the pipeline system. The invention also provides an installation method of the automatic spraying pipeline system. The automatic spraying pipeline system comprises a main pipeline, a stem pipeline, a fire-fighting hose, fittings fixed on a keel and a shower nozzle, and is characterized in that: the main pipeline and the stem pipeline are arranged inside a roof truss layer above a static pressure box; one end of the fire-fighting hose is connected with the stem pipeline and the other end is communicated with a branch pipeline through bends and short tubes; the short tubes pass through the roof of the static pressure box; the other end of the branch pipeline is connected and communicated with the shower nozzle fixed on the keel. When in installation, the main pipeline and the stem pipeline inside the roof truss layer above the static pressure box are installed at a certain place; the fire-fighting hose is installed with one end being connected with the stem pipeline; the stem pipeline is installed at the place and is communicated with the other end of the fire-fighting hose through the short tubes and the bends; connectors fixed on the keel are installed and a FFU keel is connected with the branch pipeline through the connectors of the keel; the air pressure and the water pressure of regional pipelines are tested; the shower nozzle is installed.

Description

(1) Technical field [0001] The invention relates to an automatic spraying pipeline system and an installation method thereof, which are used for the pipeline engineering of the automatic spraying system in a clean workshop in the form of a static pressure box. (2) Background technology [0002] For the current domestic clean workshop, see figure 1 , 2 Generally, the lower ceiling is FFU keel, and the upper ceiling is a double-layer ceiling large bay static pressure box with sandwich color steel plate. It is arranged in the static pressure box. In addition, in the clean workshop with the highest cleanliness level of ISO-2, in order to ensure the safety of the production equipment, the automatic spray system mostly adopts the pre-action type, that is, the gas is usually flushed into the pipeline system. In order to compress the air, it is mainly to prevent the system from false alarms or the usual leakage of the pipeline system, which causes the system to leak and damage the...

Problems solved by technology

[0002] At present, domestic clean workshops, see figure 1 , 2 Generally, the lower ceiling is FFU keel, and the upper ceiling is a double-layer ceiling large-bay static pressure box with sandwich color steel plate. The automatic sprinkler system is connected to the main pipeline in the workshop production area. Arranged in the static pressure box, in addition, in the clean workshop with the highest cleanliness level of ISO-2, in order to ensure the safety of the production equipment, the automatic spray system mostly uses the pre-action type, that is, the gas is flushed into the pipeline system at ordinary times. It is used to compress air, mainly to prevent system false alarm or pipeline system leakage and other reasons, causing system leakage to damage process equipment. When a fire occurs, the spray pump is turned on and the system is flushed. To ensure that water can enter the system normally, At the highest point of each partition system, an electric exhaust valve is set to link with the main system so that the air in the system can be discharged when flushing. Therefore, there are many pipe fittings and valves in the pipeline system. In addition, this kind of clean workshop has a high headroom and spray The main pipeline of the sprinkler system is arranged in the static pressure box, the construction of the supervisor is difficult, the amount of high-altitude work is heavy, it is extremely unsafe, and the construction efficiency is very low; Other majors (such as purification and decoration, HVAC, electrical and other majors) have a wide range of intersecting operations, and it is difficult to arrange the construction sequence of each major, which makes it difficult to control the construction progress; There are many pipeline nodes in the static pressure box, so there are many leakage points, which pose a great threat to the safety of the process equipment in the plant
