The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

referring to fig. 1, the present invention provides a technical solution: the novel soft sealing gate valve encryption lock comprises a valve body 1, a valve cover 2, a valve rod 3, a valve clack 4, a lock mechanism 5 and a key mechanism 6, wherein the valve cover 2 is fixed on the valve body 1 through a fixing bolt 21, the valve rod 3 sequentially penetrates through the valve cover 2 and the valve body 1, the valve clack 4 is connected onto the valve rod 3, the key mechanism 6 is arranged at the top end of the valve cover 2, the key mechanism 6 comprises a hand wheel bolt 7, a hand wheel 8, a key main body 9, a first magnetic ring 10 and a clamp spring 11, the hand wheel 8 is installed on the valve cover 2 through the hand wheel bolt 7, the key main body 9 and the first magnetic ring 10 are arranged at the top end of the valve cover 2, the clamp spring 11 is arranged below the first magnetic ring 10, the lock mechanism 5 is arranged below the key mechanism 6, the lock mechanism 5 comprises a lock cover 12, a second magnetic ring 13, a floating, The floating piece 14 and the magnetic ring III 16 are arranged in the lock body 15, the magnetic ring II 13 and the floating piece 14 are arranged below the lock cover 12, and the magnetic ring III 16 is arranged below the lock body 15.

Further, a copper nut 17 is arranged below the lock mechanism 5, a plurality of sealing elements 18 are arranged on the copper nut 17, and a check ring 19 is arranged at the upper end of the copper nut 17.

Further, gears 20 are arranged on the inner side of the lock body 15 and the floating piece 14, and the gear 20 on the inner side of the lock body 15 and the gear 20 on the inner side of the floating piece 14 are matched with each other.

Further, the lock mechanism 5 is made of stainless steel material.

Further, the valve rod 3 and the lock cover 12 are integrally welded.

Further, the valve flap 4 is of an inverted sealing structure.

The working principle is as follows: the invention relates to a novel soft seal gate valve encryption lock, when a floating part 14 is at the existing position without a key, the floating part 14 is pushed upwards due to the interaction of a magnetic ring II 13 and a magnetic ring III 16, so that the floating part 14 slides to the highest point, a gear 20 on the inner side of a lock body 15 is matched with a gear 20 on the floating part 14, the floating part 14 can only slide up and down on a valve rod 3 and cannot rotate, at the moment, when a lock cover 12 is rotated through a hand wheel 8, the valve rod 3 cannot be driven when the lock cover 12 is rotated because the valve rod 3 and the lock cover 12 are integrally welded, so that a valve clack 4 cannot normally supply water, when the key is placed on the lock cover 12, under the interaction of the magnetic ring I10 and the magnetic ring II 13, the floating part 14 moves downwards, when the acting forces of the magnetic ring III 10 and the magnetic ring III on the magnetic ring II 13 are balanced, the floating piece 14 just in time breaks away from the lock main part 15, thereby can drive the lock cover 12 when rotating the hand wheel 8 and rotate, the valve rod 3 is that the disjunctor is welded with the lock cover 12, valve rod 3 just can rotate like this, the valve just can be switched on and off at any time, when normally supplying water, when wanting to close the valve, can open with the dedicated key that adds magnetism, high durability and convenient operation, the hand wheel 8 leaves valve body 1 and just locks immediately, the whole materials that use of lock main part 15 are stainless steel materials, safe and reliable in utilization, easy maintenance, copper nut 17 and retaining ring 19 and sealing member 18 that set up can effectively guarantee that copper nut 17 is difficult for going out, guarantee normal water supply.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
