What parts are the components of the fire extinguisher, and what are the various parts of the fire e

Part composition: cart type dry powder.

The fire extinguisher is mainly composed of a cylinder, a head assembly, a nozzle assembly, a frame assembly, etc.

The portable dry powder fire extinguisher is mainly composed of a cylinder, a bottle head valve, a spray hose (nozzle), etc.

Principle: Compressed carbon dioxide is used to blow out dry powder (mainly containing sodium bicarbonate) to extinguish fires.

Scope of application: It has excellent properties such as good fluidity, high injection rate, non-corrosive container and not easy to deteriorate, in addition to being used to extinguish general fires, it can also be used to extinguish fires caused by the combustion of oil and gas.

The name of each part of the fire extinguisher: pressure handle, pressure gauge, nozzle, powder container.

The cylinder is the canister-like thing that holds the extinguishing agent. The valve, also known as the head, is the part above the fire extinguisher, which mainly controls the spraying and preservation of the fire extinguishing agent. The safety pin is a device to prevent the valve from opening, and only when the safety pin is in it, the fire extinguisher will not relieve pressure and can extinguish the fire.

The siphon is a tube that sucks out the fire extinguishing agent from the fire extinguisher bottle and then sprays it out, this tube is very important, without its existence, our bottle of fire extinguisher cannot spray out the fire extinguisher. The main purpose of the secret combat brigade attack seal is to prevent the seal from being loose. The pressure indicator is mainly on the head of the instrument, and the base brother detects the pressure of the fire extinguishing agent in the cylinder, because the pressure is too strong or insufficient will affect the effect of fire extinguishing, and the pressure indicator can let you know the pressure of the fire extinguisher at any time to prevent the use of the expected requirements.

There are many types of fire extinguishers, and there are different ways to classify them.

1.According to its mode of movement, it can be divided into: portable type and cart type;

3.According to the fire extinguishing agent filled, it can be divided into: foam, dry powder, carbon dioxide, water, etc.

1. Isolation method: Isolate or remove the burning place or object from the surrounding combustibles, and the combustion will stop due to the lack of combustible substances. In practical use, such as removing combustible, flammable and combustible items that can be close to the fire source; Move the burning object to a safe place; Close the valves of combustible gas and liquid pipelines to reduce and stop combustible substances from entering the combustion area, etc.

2. Suffocation method: prevent air from flowing into the combustion area or dilute the air with non-combustible substances, so that the combustible materials cannot get enough oxygen and extinguish. Practical application is time, such as covering objects with non-combustible or refractory substances such as asbestos blankets, wet sacks, yellow sand, fire extinguishers, etc.; Closed cabins, doors and windows of buildings, holes, etc., and the top cover of equipment containers, suffocating the combustion source.

3. Cooling method. Spraying the extinguishing agent directly onto the combustibles; to reduce the temperature of the combustible. When the temperature of the combustible material is lowered below the ignition point of the combustible substance, the combustion stops. Or spray the extinguishing agent on the combustible material near the fire source to prevent the influence of radiant heat**.

4. Chemical inhibition fire extinguishing method: spray the chemical fire extinguishing agent into the combustion zone to participate in the chemical reaction of combustion, so that the combustion is stopped. The fire extinguishing agents used in this fire extinguishing method include Chenglong brand high-efficiency water system fire extinguisher.
