What are the high-pressure water mist nozzles?

High-pressure water mist nozzles are commonly used in water mist devices and are in great demand in the fire protection field. So what are the high-pressure water mist nozzles? High-pressure water mist nozzles are mainly divided into two types: open nozzles and closed nozzles. The main difference between the two is that closed nozzles have one more temperature-sensing glass ball device than open nozzles. There are many appearance structures of high-pressure water mist nozzles, and the appearance can generally be customized according to the customer's application scenario.

1. High-pressure water mist open nozzle

The high-pressure water mist open nozzle does not have a temperature sensing or locking device. The entire device is in a normally open state. When a fire occurs, all open nozzles in the system protection area where the fire is located will emit water together to extinguish the fire.

The commonly used models of high-pressure water mist open nozzles are mainly as follows: XSW-T0.3/10, XSW-T0.5/10, XSW-T0.7/10, XSW-T0.9/10, , XSW-T1.7/10, XSW-T2.0/10, XSW-T2.5/10, XSW-T3.0/10, XSW-T3.5/10,

There are many structural types of high-pressure water mist open nozzles, and customers with special needs can also find manufacturers to customize them. The appearance and structure of several common high-pressure water mist open sprinklers currently on the market are as follows:

2. High-pressure fine water mist closed nozzle

The high-pressure water mist closed 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.

Commonly used models of high-pressure water mist closed nozzles include: XSW-T1.0/10-57℃φ2, XSW-T1.2/10-57℃φ2, 2.5/10-57℃φ2, XSW-T3.0/10-57℃φ2, XSW-T3.5/10-57℃φ2, XSW-T4.0/5-57℃φ2,

The structural type of high-pressure water mist closed nozzles can also be customized according to needs. The following is the appearance structure of common high-pressure water mist closed nozzles on the market:

3. Price of high-pressure water mist nozzle

The market price of high-pressure water mist nozzles is quite mixed. There are some with a unit price of tens, and some with a unit price of one or two hundred. There are many main reasons. One is the material, which is also stainless steel, but the price difference is very big. Secondly, the number of holes in the nozzle is different, and the price will be different. In addition, high-pressure water mist nozzles with a unit price of tens and a unit price of one or two hundred, in addition to differences in materials, also have great differences in mist shape, performance, etc. Especially customers who have high requirements for nozzle quality, such as those used in engineering projects, still need to be cautious when choosing nozzles.

4. Structure of high-pressure water mist nozzle

A high-pressure water mist nozzle mainly contains one or more nozzles, consisting of a nozzle body, a nozzle holder, a nozzle, a diversion device and a filter. The closed water mist nozzle has an additional temperature-sensitive glass ball device. Under the action of high pressure, water is atomized into micron-level water mist using mechanical means such as centrifugation, impact or jet flow.

5. High-pressure water mist nozzle manufacturer

Currently, there are not many manufacturers of high-pressure water mist nozzles across the country. Among them, Lanzhong Electromechanical has been developing in this industry for nearly ten years. It has the ability to design and produce different types of high-pressure water mist nozzles, and provides customized services for fine water mist nozzles according to customer needs.

Lanzhong Mechanical and Electrical participated in the preparation of relevant standards and monographs on water mist and perfluorohexanone fire extinguishing technology, and established cooperative research and development relationships with multiple inspection agencies, universities, and enterprises. At present, in the product fields of fixed water mist fire extinguishing systems and mobile water mist fire extinguishing devices, various types of water mist nozzles and water mist spray guns have been developed; in the field of perfluorohexanone fire extinguishing systems, various types of nozzles and nozzles have been developed in cooperation with customers for the perfluorohexanone fire extinguishing agent; in the field of fixed fire extinguishing systems for bus cabins, Lanzhong has developed core components such as DC water pumps and nozzles.

High-pressure water mist nozzles are mainly used in the field of fire protection. Pure water is generally used as the fire extinguishing medium. It can extinguish Class A, B and electrical fires. It is suitable for use in substations, power grids, libraries, archives, subway stations and other scenes. In different scenarios, the structural design and performance requirements of high-pressure water mist nozzles may be different, so customers should not blindly purchase, but should provide reasonable parameters for selection or customization based on actual applications.
