Guangzhou Tianyi Class A fire door: open and convenient self-closing performance

A fire door is a door that meets the requirements for fire resistance stability, integrity, and insulation for a certain period of time. It is a fireproof partition with certain fire resistance, such as in fire compartments, evacuation stairwells, vertical shafts.

In addition to the function of ordinary doors, fire doors have the function of preventing the spread of fire and the spread of smoke, which can prevent the spread of fire for a certain period of time and ensure the evacuation of personnel.

Classification basis

There are many types of fire doors.

By material

There are wooden fire doors, steel fire doors, steel fire doors, other fire doors, etc.;

Wooden fire door

Use fire-resistant wood or flame-retardant wood products as door frames, door leaf frames, and door leaf panels.

Steel fire door

The door frame, the door leaf frame and the door leaf panel are made of steel material, and if the material is filled in the door leaf, the fireproof and heat insulating material which is non-toxic and harmless to the human body is filled, and the door with certain fire resistance performance composed of fireproof hardware parts is matched.

Steel wood fire door

Door frames, door leaf frames, and door leaf panels are made from steel and flame retardant wood materials or flame retardant wood products.

Other material fire doors

Use inorganic non-combustible materials other than steel, flame-retardant wood or non-combustible wood products or partially use steel, flame-retardant wood, and flame-retardant wood products to make door frames, door leaf frames, door leaf panels, and fill materials in the door leaf to fill A fire-proof and heat-insulating material that is non-toxic and harmless to the human body, and is equipped with a fire-resistant hardware fitting with a certain fire-resistant door.

Product parameters:

The difference between the anti-theft door and the fire door is that the main function of the anti-theft door is that the anti-smashing sealing performance is better. Generally, the door cannot be opened without a key outside the door, and the filler in the door panel is not a fireproof material. The security door must have the "FAM" mark and refer to the general technical condition GB17565-2007 of the security door. Although the fire door is also made of steel, but the door panel is filled with fireproof material, the thickness of the door steel plate also has different requirements. The steel door is an ordinary steel door. It also has a certain anti-theft function, but the anti-smashing performance is relatively poor. The general street processing factory is this type.

Only Shanghai and Chengdu have local standards for fire-resistant security doors. In other places, they can only be called fire-proof entrance doors, that is, they can reach the national fire-proof Class A or Class B fire door standards, and (with fire door cores) Class A and Class B standards. Generally divided by anti-burning time. At the same time, the flood prevention requirements are achieved in the following aspects:

The thickness of the door frame is 1.5, and the thickness of the front and back of the door leaf is 0.8.

The lock has anti-smashing function, that is, the lock body has both the oblique locking tongue and the square locking tongue, and has a quick opening function, and is the best in the twisting type, but the heaven and earth lock is not allowed.

Both the lock and the cat's eye shall have a fire detection report, and the Class B fireproof entry door may be fitted with a door collar. Class A is not allowed to be installed.

At the time of acceptance, the merchant shall provide a fireproof type approval certificate, a fire detection report, and a metal entry door inspection report. Fire detection report for locks and cat eyes.

The door opening direction is a fast evacuation direction and cannot be opened inside.

What are the characteristics of Guangzhou Tianyi Class A fire door?

Self-closing performance.

Observing steel fire doors for commercial premises, it can be found that fire doors can be closed by themselves after opening, while ordinary doors require human power. This is because there is an automatic door closer above the fire door. The door closers of fire doors are divided into two types: hydraulic type and spring type. The door closers are installed on the back of the fire door to protect them from high temperature. The self-closing performance of the fire door can also save energy and energy for the shopping mall. The air conditioner is turned on in the mall all year round, and many people do not have the habit of closing the door. The self-closing feature of the fire door can be automatically closed after the door is opened. , has a certain energy saving effect.

Easy to open.

The fireproof performance of steel fire doors is better than that of wooden fire doors. The material of steel fire doors is metal, which is not easy to be natural and the reliability is higher than that of wooden doors. However, because steel fire doors are made of metal, their weight is better. Big. Pushing and pulling of heavy objects is generally more difficult, but in order to facilitate people to open the fire door in an emergency, the design of the fire door will be designed to be easy to open, and the door handle of the fire door is mostly push-pull. In order to facilitate people to open the fire door easily.

Peristaltic Pump

Peristaltic pumps are a type of positive displacement pump that uses a flexible tube or hose to move fluids. These pumps are also known as roller pumps, tube pumps, or hose pumps. The name "peristaltic" comes from the way the pump works, mimicking the motion of the human digestive system, where muscles contract and relax to move food through the body. Peristaltic pumps work by squeezing the flexible tubing or hose with a series of rollers or shoes that move along the length of the tubing. This creates a vacuum that draws fluid into the tube, and then pushes it through the tubing as the rollers move along. The flow rate of the fluid is determined by the speed of the rollers and the diameter of the tubing. DYX mini peristaltic pumps are a reliable and versatile option for moving fluids in a wide range of applications.
