Beijing closed water mist nozzle

Beijing closed-type water mist nozzles are available in high-pressure and medium-low pressure, which can be used in different scenarios to achieve good fire-extinguishing effects. There are many types of closed water mist nozzles in Beijing. The prices of different types of closed water mist nozzles are also different. It depends on the price quoted by the manufacturer. The following is an introduction to Beijing closed water mist nozzles:type、model、parameter、price、factory、addressand other related content.

What is a closed water mist nozzle?

The closed water mist nozzle is a normally closed nozzle. The temperature sensing and locking device of the nozzle will only fall off and open the nozzle under a predetermined temperature environment. Therefore, when a fire occurs, this sprinkler system will only turn on the nozzles that are in the flame or near the fire source to extinguish the fire.

The closed valve is usually closed, but there is water in front and behind the valve. When a fire breaks out, the high temperature causes the glass bubble of the closed sprinkler head to rupture. When the water spurts out, the valve detects a decrease in water pressure at the rear, thus sending a warning signal to the alarm system, which then activates the fire pump to supply water.

1. Types of closed water mist sprinklers in Beijing

Closed water mist nozzles can be divided into high-pressure closed water mist nozzles, medium-pressure closed water mist nozzles and low-pressure closed water mist nozzles according to working pressure. These three types of nozzles are used in different types of closed water mist systems.

1. Low-pressure water mist fire extinguishing system: P<1.20Mpa

2. Medium pressure water mist fire extinguishing system: 1.20Mpa

3. High-pressure water mist fire extinguishing system: P>3.50Mpa

2. Beijing closed water mist nozzle model

There are two types of closed water mist nozzles commonly used in Beijing: high-pressure water mist closed nozzles and medium-pressure water mist closed nozzles. Their models are generally composed of parameters such as the flow coefficient of the nozzle, working pressure, glass ball temperature and size. The conventional models of closed water mist nozzles in Beijing include the following:

3. Beijing closed water mist nozzle parameters

There are many parameters for closed water mist nozzles. First, there are some parameters of the nozzle, such as the material of the nozzle, specifications and sizes of the nozzle, etc.; secondly, there are spray parameters, such as mist shape, atomization angle, etc.; there are also some performance parameters, such as working pressure, flow rate, etc. If Beijing closed water mist nozzles are customized, at least the following parameters need to be provided:

(1) Nozzle (nozzle) structural type, such as appearance size, thread, structure, etc.;

(2) Medium;

(3) Flow coefficient;

(4) Performance requirements, such as droplet diameter, range, spray angle, installation parameters, etc.;

(5) Minimum and maximum working pressure;

(6) Application site and working environment;

(7) Material;

(8) The closed nozzle should also provide glass ball parameters.

4. Price of closed water mist nozzles in Beijing

The market price of closed water mist nozzles in Beijing ranges from high to low, with the unit price basically around 200 yuan. Generally speaking, the price of closed water mist nozzles in Beijing is related to the materials used, the difficulty of design and processing, the wholesale quantity, glass balls, etc. Take the material as an example, stainless steel and brass are used to produce closed water mist nozzles, and the cost is different; and the wholesale quantity, the unit price of wholesale 100 pieces of closed water mist nozzles and 1,000 pieces are also different. Of course, the specific price must be based on the quotation of the Beijing closed water mist nozzle manufacturer.
