How much does a fine water mist nozzle cost?

Water mist nozzles have been used in many fields due to their good fire extinguishing performance. So how much does a fine water mist nozzle cost? There are two types of water mist nozzles on the market: open and closed. The prices of these two types of water mist nozzles are different. The unit price of an open water mist nozzle is generally 100 yuan, while the unit price of a closed water mist nozzle is around 200 yuan. The specific price depends on the manufacturer's quotation.

1. Price of open water mist nozzle

Reference unit price: 100 yuan/piece

The open water mist nozzle does not have a temperature sensing or locking device and is in a normally open state. When a fire occurs, all open sprinklers in the system protection area where the fire is located will emit water to extinguish the fire. The valve part and the nozzle part of the open sprinkler system are different. The valve part is electric or manual. When a fire occurs, the fire alarm system will alarm and link the control device to electrically start the valve, or manually start the valve, so that the valve opens, and the water from the main pipe reaches the nozzle through the valve and is sprayed out to extinguish the fire.

Mechanism of open water mist fire extinguishing:

Under quasi-working conditions, the high-pressure water mist fire extinguishing system maintains a certain pressure in the pipe network from the outlet of the pump unit to the area valve. When the pressure is lower than the set starting pressure of the pressure-stabilizing pump, the pressure-stabilizing pump starts to maintain a stable pressure in the system pipe network. When the pressure-stabilizing pump runs for more than a certain period of time and the pressure still cannot be reached, the main pump will start and the pressure-stabilizing pump will stop. The water inlet of the equipment regulating water tank is equipped with a water replenishment solenoid valve. The water source enters the water tank after passing through the filter and water replenishment solenoid valve. The water tank is equipped with a liquid level controller to realize automatic control of the water level of the water tank. The water replenishment solenoid valve opens when the water level in the water tank is low and closes when the water level is high.

2. Price of closed water mist nozzles

Reference unit price: 200 yuan/piece

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

Mechanism of closed water mist fire extinguishing:

Under quasi-working conditions, the high-pressure water mist fire extinguishing system maintains a certain pressure from the outlet of the pump unit to the pipe network in front of the nozzle. When the temperature of the glass bubble of the closed nozzle reaches the operating temperature, the glass bubble breaks and the pipeline pressure drops. When the pressure is lower than the set starting pressure of the pressure-stabilizing pump, the pressure-stabilizing pump starts to maintain a stable pressure in the system pipe network. When the pressure-stabilizing pump runs for more than a certain period of time and the pipe network pressure is still not reached, the main pump starts and the pressure-stabilizing pump stops. The flow switch feeds back the spray signal of the system. After receiving the feedback signal, the host computer turns on the spray indicator light.

3. Factors affecting the price of water mist nozzles

The prices of water mist nozzles on the market are very complicated, each one is different, and different types of water mist nozzles have different prices. Even if different customers buy the same water mist nozzle, the price quoted by the manufacturer may be different. So what factors affect the price of water mist nozzles?

1. Purchase quantity

The quotation of fine water mist nozzles is affected by the customer's purchase quantity. Generally, manufacturers will have minimum order quantity requirements, and the unit price is also different in each quantity range. For example, the quotations of 100 pieces and 1,000 pieces of fine water mist sprinklers are different.

2. Processing difficulty

The price of customized water mist nozzles is generally higher than that of conventional models. Customization requires technicians to design and draw, and production personnel process according to the drawings. They need to constantly adjust the data. After processing, the mist shape, flow rate, etc. need to be tested to see if they meet the requirements. Therefore, the price of fine water mist nozzles is affected by the difficulty of processing.

3. Raw materials

There are many kinds of raw materials used in the production of water mist nozzles, such as stainless steel, brass, alloys, etc. Different raw materials have different prices for water mist nozzles.

4. Manufacturer

Suppliers of fine water mist nozzles are divided into direct sales from manufacturers and agents. They wholesale fine water mist nozzles from manufacturers and agents. The prices are usually different.

The price of water mist nozzles is basically around one or two hundred. Of course, it cannot be generalized. Many customers need to individually customize water mist nozzles of special models and specifications, so the price cannot be calculated by conventional prices. Currently, there are many manufacturers of fine water mist nozzles. Anhui Lanzhong Electromechanical can customize different types of fine water mist nozzles according to customer needs to meet the application needs of different customers.
