Seamless, anti-blocking, waterproof, anti-corrosion, easy to use; Deeply favored by water supply, heating, gas and other industries.
principle of operation
It consists of spring, lock head and valve body. The valve lock can be attached to the valve at will, but it cannot be removed at will. It is characterized in that the side end of the lock head is provided with four spring holes at equal intervals, and springs abutting against magnetic marbles (balls) are arranged in the spring holes; When the letter "C" on the key is aligned with the letter "C" on the magnetic lock cover and inserted into the lock head, a magnetic marble corresponding to the lock head is fixed at one end of the key close to the lock head, and the upper end of the valve stem on the valve body is provided with a rotary valve sleeve matched with the valve hole opened at the lower part of the lock head. Press the magnetic lock lightly by hand and lift it lightly to open the magnetic lock, then the valve switch can be operated. When closing, insert the magnetic lock directly on the valve.
There is no key. Find two magnets to attract the magnetic beads on both sides to open it.
