Background
The paint shop of the automobile factory is the most important shop of the whole automobile factory, the paint spray booth is the key process component of the paint shop, the whole process environment condition, especially the air quality, is directly related to the quality of the final finished product, therefore, the particle content in the air needs to be strictly controlled, and the gap between the pressure equalizing chamber and the paint spray booth needs to be strictly sealed to prevent the entry of the trapped dust particles. Simultaneously because the inside long-term operation of spraying paint of spray booth, the coating cloud can remain in the internal portion of equipment room, and this makes the spray booth produce the conflagration in becoming the painting workshop easily, and the higher region of conflagration danger level, and automatic sprinkler system is as a common and effectual fire extinguishing systems, is widely used for application equipment fire extinguishing systems.
As the industry has no uniform installation standard for equipment fire protection, the fire protection construction unit mainly adopts the following two modes according to the field experience of the fire protection construction unit: one is to adopt a traditional decorative disc embedded on the top plate of the chamber body; the second is to arrange the concentric reducing pipe at the lower side of the top plate of the chamber body and then seal the gap between the reducing pipe and the top plate by sealant. The disadvantages of the two methods are that the coating workshop process chamber body has industrial vibration relative to the suspended ceiling of the civil building, the decorative disc embedded on the top plate is easy to fall off after a period of time, and meanwhile, the sealant can gradually lose efficacy under the influence of aging and vibration. This indirectly affects product quality, and therefore, a sprinkler head mounting structure capable of ensuring sealing performance for a long time is desired.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the technical defects in the prior art, and provides a nozzle mounting structure of a fire-fighting water-spraying fire-extinguishing system of process equipment in a coating workshop, which can effectively offset the influence of industrial vibration and sealant aging on sealing performance and has the effect of long-term sealing.
The technical scheme adopted for realizing the purpose of the utility model is as follows:
the utility model provides a coating workshop process units fire control sprinkler system shower nozzle mounting structure, includes:
by spraying water nozzle stub, back of the body lock nut, rubber seal, stainless steel gasket, concentric reducing pipe and connecting through process chamber body roof and form, the minor diameter pipe and the sprinkler shower nozzle threaded connection of concentric reducing pipe, it forms external screw thread portion to spray water nozzle stub lower part, back of the body lock nut dress is in on the external screw thread portion, rubber seal arranges in back of the body lock nut and cover between process chamber body roof on the external screw thread portion, the external screw thread portion that sprays water nozzle stub certainly downwardly extending in the mounting hole on the process chamber body roof passes and is located process chamber body roof below the stainless steel gasket with behind the internal thread connection of the big diameter pipe of concentric reducing pipe by back of the body lock nut reverse screwing will rubber seal compresses tightly on process chamber body roof.
Wherein, the rubber sealing ring adopts a non-silicon rubber sealing ring.
Wherein, a section of external thread is formed on the small-diameter pipe of the concentric reducing pipe so as to be connected with the internal thread of the sprinkler head.
The utility model utilizes a threading machine to thread a short sprinkling pipe, reserves enough length, installs a back nut and a rubber sealing ring on a top plate of a process chamber body, sleeves a stainless steel gasket on the lower side of the top plate of the process chamber body, respectively screws and fixes a concentric reducing pipe and a sprinkling nozzle by a spanner, screws the back nut reversely, and compresses the rubber sealing ring on the top plate of the process chamber body. Compared with the installation form of the fire-fighting sprinkler head of the traditional coating workshop process equipment, the utility model can ensure that the stainless steel decorative gasket cannot fall off; the use of the back tightening nut can ensure that the spray head connecting piece is tightly connected with the chamber top plate; the rubber sealing ring effectively seals a gap between the rubber sealing ring and a top plate of the chamber body, and prevents static pressure chamber dust from entering the paint spraying chamber body to cause paint surface pollution.
