Preaction Alarm check Valve for water sprinkler system

Introduction     
                                                                               
ZSFM/ZSFG type deluge alarm valve which is based on GB5135.5-2003 standard shows lever type structure and has the anti-returning function. The valve is widely used in open sprinkler system, for instance, deluge system, water curtain system, water mist system. The deluge valve starts when the pressure in the diaphragm is released then the pressure of the water supplying side pushes open the valve clack. To release the pressure in the diaphragm, there are quite some ways,such as electric conduct, wet type conduct, dry type conduct. This type of automatic fire fighting system is suitable for hospitals, hotels, factories, malls, airports, libraries, gym, exhibition center.

1. ZSFG Deluge valve is a one way valve, which is opened by wet method, dry method, electric method or manual method, can make the water automatically flow into sprinkler system in one way and at the same time make the alarm. It is widely used in sprinkler system, pre-acting system, water spray projecter system or water curtain system.
 
2. Sprinkler system mainly consists of deluge valve, automatically open and control system, tube web, open sprinkler and water supply system. It is used for dangerous fire, more combustibles, huge heat generated, big fire and spread rapidly fire with inflammable and explosive places, and the required temperature is no less than 4 degree centigrade. Such as Alcohol solvent products factory, the place of flammable liquid spray operation, Chemical goods warehouse and stage grape
 
3. Pre-acting system mainly consists of deluge valve, wet valve, automatically open and control system, tube web, close sprinkler and water supply system. It is widely used for higher temperature or cold place, with quick alarm, quick sprinkler, full function and widely usage advantages. It is normally fixed for the place where need water to fire fighting, not allowed sprinkler for non fire, such as library for precious books, file rooms and storage with precious goods.
 
4. Water spray projecter system mainly consists of deluge valve, automatic open and control system, tube web, water spray sprinkler and water supply system. It is widely used for put out solid fire, liquid fire, electric fire, flammable gas and liquid I, II, III, such as paper, textile place, cable, oil, gas and flammable liquid containers.
 
5. Water curtain system consists of deluge valve, automatic open and control system, tube web and water supply system. It is widely used for window, and wall for flammable construction. It is normally used together with fire proof curtain, glass wall, with isolation function.

Asphalt Mixing Plant

Asphalt mixing plant is one of the key equipment for road construction. It is mainly used in the production of asphalt mixture for paving road surfaces. Asphalt mixing plant consists of a number of parts, including dosing system, dryer, agitator, dust removal system, fuel system and so on.

The batching system is one of the core parts of Asphalt mixing plant. It is responsible for adding various raw materials to the blender in a certain proportion. These raw materials include asphalt, sand, gravel and other additives. The batching system usually consists of a weighing sensor, a batching bucket and a batching transfer device.

The dryer is another important part of the Asphalt mixing plant. It is mainly used for drying raw materials such as sand and stones. There are heating elements and rotating agitators inside the dryer, which can make the raw materials fully heated and mixed evenly.

Mixer is one of the core parts of Asphalt mixing station. It is responsible for mixing various raw materials together to produce a high quality asphalt mixture. The agitator usually consists of multiple mixing blades, which can fully mix the raw materials to ensure the stable quality of the asphalt mixture produced.

Dust removal system is one of the important components of Asphalt mixing plant. It is mainly used to collect dust and exhaust gases generated during the production process. The dust removal system is usually composed of multiple filters, which can effectively filter out dust and exhaust gas to ensure a clean working environment and air quality.

Fuel system is one of the key parts of Asphalt mixing plant. It is responsible for providing the fuel to power the Asphalt mixing plant. The fuel system usually consists of a fuel pump, a fuel filter and a fuel injector.

Asphalt mixing plant is a kind of high efficiency asphalt mixture production equipment, widely used in road construction field. It has the advantages of high automation, high production efficiency, stable product quality and so on, and provides a strong support and guarantee for road construction.
