Personal defense door, as the name suggests is to prevent people from accidents door, in a crowded place basically will see, especially in some of our large supermarkets, the door at the exit of the security basically is the door. At the same time, there are a lot of classifications of human security doors, different classifications play a role in a little bit not the same, then how to correctly buy the human security door, or how to buy a good human security door? Next, I will introduce you to several manufacturers of security doors.

Classification and characteristics
1, ordinary single, double protection closed door and closed door
This type of door stereotypes the earliest, has been widely used. It is characterized by simple structure, reliable operation, easy maintenance, suitable for all kinds of human defense project entrance and exit. However, because it has a threshold, so the personnel, vehicles in and out of frequent projects, such as underground shopping malls, etc., has been less used, and instead of the corresponding size and load level of the same live threshold door or landing door.
2, live threshold single, double protection and confinement door
This type of door is characterized by not installing the threshold in the usual way, the ground is flat, easy to pass personnel and vehicles, rapid installation of the threshold in the event of a war to meet the requirements of protection and confinement function to quickly realize the conversion of peace and war function.
This type of door is suitable for the combination of peace and war underground shopping malls, hospitals, warehouses, underground parking garages and other human defense project entrances and exits.
3, hose explosion-proof wave valve
Hose explosion-proof wave valve is a kind of shock wave under the action of overpressure can be quickly closed valve, hose deformation, the vast majority of the shock wave blocked outside the project, a small portion of the shock wave into the head of the project diffusion chamber to further expansion and diffusion? Finally weakened to the allowable safety pressure, when the role of the hose explosion-proof wave valve on the air shock wave overpressure design value is not greater than 0.3MPa, the wave elimination system can be canceled diffusion chamber, the direct use of the hose explosion-proof wave valve; hose explosion-proof wave valve is only applicable to the project's ventilation system, does not apply to the smoke exhaust port.
4, pendulum explosion-proof wave (shielding) valve
Pendulum explosion-proof wave valve structure is simple, easy to use and maintain, can be used for the project's air intake, exhaust or smoke exhaust, pendulum explosion-proof wave shielding valve is in the ordinary pendulum explosion-proof wave valve on the basis of an increase in shielding, anti-electromagnetic pulse capability for the Ⅱ level.
5, landing double protection and confinement door and confinement door
This type of door is characterized by no threshold on the ground at ordinary times, to facilitate the passage of personnel or vehicles; wartime will be the door to turn, landing and panning in order to meet the requirements of the protection, confinement, which comes with a small door to facilitate the temporary entry and exit of the personnel, the level of the war is converted quickly. The new landing door improved its lifting mechanism, more convenient operation.
6, connecting the mouth of the two-way force double protection closed door
This type of door is set in the two adjacent protection unit connecting the mouth of the protection of the closed partition wall, which is characterized by the ground is flat without a doorway, can be two-way respectively, two-way force, two-way confinement, quick conversion of peace and war.
7, ramp open double doors
This type of door is suitable for setting up in the ramp terminal of the entrance and exit of the underground civil defense project, the door to the internal opening of the project, there is no protruding threshold of the ground at ordinary times, the conversion of peace and war is fast.
8, protection against fire closed door, fire door
The salient feature of such doors is the ability to prevent disasters, the door in the fireproof filler, but also closed measures, so the fire, smoke, water; and other protection closed door, wartime, but also against shockwaves, biological warfare agents and chemical warfare agents, to comprehensively meet the requirements of the human defense project The combination of peace and war requirements.
This type of door can be installed in the fire safety exit, as well as the partition wall between two neighboring protective units.
9, electronically controlled door
Electrically controlled doors are electronically controlled protection of the closed door, electronically controlled closed door, electronically controlled closed shielding door and electronically controlled protection of four major categories of doors, including electronically controlled closed shielding door of the EMP prevention capability of Ⅲ. This type of electronically controlled door manual lightweight and flexible, for a machine with two electric control door, that is, switching the door and switch lock **** with a power unit, with in situ control, remote control and intelligent control (access control system) three kinds of control, and according to the project needs to be added to the safety monitoring and electromagnetic locking device.
10, blocking plate
(1), connecting the mouth protection closed blocking plate
Connecting the mouth protection closed blocking plate is characterized by the use of assembled, monomer quality light, size modulus, easy to install. It is suitable for rapid blocking of the connecting opening of the partition wall between two protection units in times of war, and is not applicable to the blocking of the external penetration holes of the human defense project.
The air vent protection airtight blocking is suitable for quick blocking of the air duct holes on the partition wall between two protection units in times of emergency, not suitable for blocking of external wall holes.
(2), the air wall protection closed blocking plate
This blocking plate can be used for blocking the usual use, wartime without the use of the hole. It is characterized by the usual can not install the blocking plate (but to be processed in the vicinity of the designated location), according to the pre-set conversion time limit will be quickly installed in wartime blocking plate to meet the requirements of the protection of confinement. According to its setup location can be divided into protection unit vent or connecting mouth with two-way force protection closed blocking plate and airside wall protection closed blocking plate two categories.
11, protection closed shielding door and closed shielding door
These doors have protection, confinement, shielding or confinement, shielding composite function, the protection level of level II.
Several manufacturers of human defense doors are introduced here, in general, these manufacturers have been establishing the company for a long time, the business products have always been the attention of the people. It is believed that in terms of quality, it is comparable to the other manufacturers, or even can be better. From the price point of view, the price of the human defense door of these families is not very comparable, probably because it is a domestic brand, so the price is more acceptable.
