Embodiment:

Below in conjunction with accompanying drawing this utility patent is described further.

The type gate valve magnetic-type with lock of present embodiment partly is made up of gate valve main body 1, magnetic lock 2, strong magnetic torsion key 3 three, and this key is powerful torsion key 3.

Gate valve main body 1 is a basic valve, and it comprises compositions such as valve body 11, flap 12, Stem Mut 13, valve rod 14, valve gap 15, gland 16.Valve rod 14 is connected and fixed through Stem Mut 13 and flap 12, and valve rod 14 is threaded for 11 one-tenth with valve body, thus rotation valve rod 14 just can actuate valve stem 14 move upward or downward with flap 12, thereby make valve opening and closing.

Magnetic lock 2 is locking frameworks, and it comprises compositions such as housing 21, locking closure 22, magnetic lock core 23, sliding pin 24, seal ring 25, and housing 21 is fixedly mounted on the gland 16; The bottom of locking closure 22 is injected in the housing 21; Be provided with seal ring 25 between locking closure 22 bottoms and the housing 21, these housing 21 inwalls are provided with circular groove 26, and sliding pin 24 has four; Their circle distribution are located at the bottom of locking closure 22 and are protruded an end; The protruding end inserts in the circular groove 26, makes housing 21 and locking closure 22 both can fix mutually, can do mutual rotatablely moving again.Magnetic lock core 23 is square; Be provided with link 27 between it and the valve rod 14, be provided with square counterbore 28 at the top of link 27, the degree of depth of square counterbore 28 and magnetic lock core 23 are of uniform thickness; Magnetic lock core 23 is placed in the square counterbore 28; The bottom of link 27 and valve rod 14 are fixed together, and link 27 is rotated with valve rod 14, on locking closure 22, form the square lockhole 29 that is complementary with magnetic lock core 23 shapes; The degree of depth of square lockhole 29 is less than the thickness of magnetic lock core 23, and locking closure 22 outer surfaces are provided with four flanges 30 that are used for transferring power.

Strong magnetic torsion key 3 is the operating stem as input torsion, and it is provided with a cover portion 31, be provided with in the cover portion 31 with locking closure 22 on four grooves 32 cooperating of flange 30, be provided with strong magnetic spare 33 at the top of cover portion 31.

During reset condition, magnetic lock core 23 places in the square counterbore 28 fully, and just magnetic lock core 23 leaves the square lockhole 29 of locking closure 22 fully; At this moment, locking closure 22 breaks away from fully with magnetic lock core 23 and cooperates, under the cooperation of sliding pin 24 and circular groove 26; Locking closure 22 can freely rotate around housing 21; It all is idle running that locking closure 22 is done any rotation, and valve rod 14 can not rotate with link 27, can not drive gate valve and open and close.During opening and closing gate valve, the cover portion 31 of strong magnetic torsion key 3 is covered locking closure 22, make groove 32 and flange 30 on the locking closure 22 in the cover portion 31 transmission torsion that cooperatively interacts; Strong magnetic spare 33 in the simultaneously strong magnetic torsion key 3 is with in the square lockhole 29 in the magnetic lock core 23 inspiration locking closures 22, and at this moment owing to receive the restriction of size, the part of magnetic lock core 23 places in the square lockhole 29; Another part places in the square counterbore 28; Rotate strong magnetic torsion key 3, torsion passes to locking closure 22, and locking closure 22 passes to magnetic lock core 23-link 27-valve rod 14 successively with torsion then; Thereby driving valve rod 14 rotates; Under the threaded function between valve rod 14 and the valve body 11, make valve rod 14 drive flap 12 and do elevating movement, realize the keying of gate valve.Take away when strong magnetic torsion key 3, the magnetic lock core promptly falls back in the square counterbore 28 automatically, replys reset condition, the gate valve locking.The strong magnetic torsion key 3 that turns clockwise is closing gate valve, is rotated counterclockwise strong magnetic torsion key 3 for opening gate valve.

Locking closure 22 is provided with seal ring 25 with housing 21 auxiliary sections, makes magnetic seal fully in locking, and can make waterproof usefulness, and security level reaches the IP68 level.

The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the utility model technological scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to the utility model technological scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from the utility model technological scheme, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the utility model.
