When the tin foil is on the door, the door will open. The video on the Internet is resounding. The cases of burglary have occurred frequently. Many citizens have scored 96,258 to ask how to prevent technical unlocking. According to the master of the Sanxiang Metropolis Office 96258 Public Service Center who has many years of experience in unlocking, the super B-class lock has good anti-theft performance and can effectively prevent technical opening.
According to the master, the anti-theft door lock cores currently used in the market are basically divided into A-class, B-class and super-B-class. Among them, the anti-destructive opening time of the A-class lock cylinder is greater than 15 minutes, and the anti-technical opening time is greater than 1 minute; the anti-destructive opening time of the B-class lock cylinder is greater than 30 minutes, and the anti-technical opening time is greater than 5 minutes; The anti-technical opening time of the anti-theft door lock cylinder is more than 4 hours.
It is understood that most of the current households use the AB lock. This type of lock has a low level of security and is extremely insecure. The thief can open it with tin foil for a few seconds. "If you feel that your own anti-theft door lock is not safe, you can consider changing a B-level lock or a super-B lock with a high anti-theft level. The Super B-class lock is detected by the public security department, but you must confirm the store when you buy it. Whether there is a detection report on the anti-theft performance of the Super B-class lock, do not buy counterfeit goods. So far, the super B-class door lock is still not easy to open technically." Master said.
In addition, whether it is safe in the home is not only to buy a high-grade lock, but also when citizens buy a door, they should pay attention not only to the aesthetics, but also to the material and whether the steel plate reaches a certain hardness. Can not be ignored. To fundamentally improve the security level of the home room, do not give the thief a chance to take advantage of it.
Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
