Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 is the utility model discloses the schematic diagram of the embodiment of valve open and close state locking device's cross-sectional view, fig. 2 is the utility model discloses the schematic diagram of valve open and close state locking device's embodiment, fig. 3 is the utility model discloses the schematic diagram of the embodiment of tapered end among the valve open and close state locking device, fig. 4 is the utility model discloses the schematic diagram of telescopic embodiment among the valve open and close state locking device, as shown in the figure, a valve open and close state locking device, include sleeve 1 and the tapered end 2 that is located sleeve 1 top, sleeve 1 is used for being connected with the valve, tapered end 2 is used for airtight to sleeve 1. One end of the sleeve 1 is provided with a first limiting bulge 3, the circle of which is positioned in the sleeve 1, the other end of the sleeve 1 is provided with a second limiting bulge 4, the circle of which is positioned in the sleeve 1, and a movable gasket 5 is arranged between the first limiting bulge 3 and the second limiting bulge 4. The middle part of the movable gasket 5 is provided with a through hole which is used for penetrating a screw rod used for adjusting the flow on the valve, and the movable gasket 5 and the second limiting bulge 4 are jointly fixed on the screw rod through a bolt. The diameter of the movable gasket 5 is larger than the diameters of the first limiting bulge 3 and the second limiting bulge 4, so that the movable gasket 5 cannot be separated from the first limiting bulge 3 or the second limiting bulge 4. The diameter of the movable washer 5 is smaller than that of the sleeve 1, so that the movable washer 5 and the screw rod cannot rotate along with the sleeve 1 when the sleeve rotates due to external force.

The lock head 2 is of an integral structure and comprises a lock cylinder 6 and a lock cap 7 positioned at the top of the lock cylinder 6. The lock column 6 is matched with the structure of the first limiting bulge 3, so that the lock column 6 can enter the sleeve 1 from the top of the sleeve 1 through the first limiting bulge 3. The bottom surface of lock post 6 is equipped with the spring 8 of vertical setting, is equipped with the through-hole of relative setting on the lateral wall of lock post 6, is equipped with the same magnetism post 9 of magnetism in the through-hole, and the through-hole is stretched out to magnetism post 9 utilizing the principle that like poles repel each other, makes magnetism post 9 card in the below of first spacing arch 3, and lock post 6 is locked in sleeve 1 this moment. The afterbody of magnetism post 9 is equipped with stopper 10 with the perpendicular setting of magnetism post 9, and stopper 10 can prevent that magnetism post 9 from deviating from in the through-hole.

The locking cap 7 is matched with the structure of the sleeve 1, so that the locking cap 7 can be placed on the first limiting bulge 3. The top surface of the lock cap 7 is provided with a key hole 11 communicated with the lock cylinder 6, the key hole 11 comprises a large hole and a small hole which are communicated with each other, the key hole 11 is used for inserting a magnetic key, and the convex blocks on the magnetic key with the small hole are matched. An elastic block 12 connected with the spring 8 is arranged in the key hole 11, and the spring 8 can enable the elastic block 12 to move up and down in the through hole and automatically reset. The spring block 12 is in the same plane with the top surface of the lock cap 7 in a free state, and plays a certain role in covering and protecting the keyhole 11. The bullet piece 12 is located the below of through-hole under the state of compressing tightly maximally, makes the magnetism key can press bullet piece 12 and stretch into between two magnetism posts 9, then utilizes the principle of opposite polarities to inhale magnetism post 9 in the through-hole, can move out or move into in to sleeve 1 with tapered end 2 from sleeve 1 this moment.

During the use, take off the valve spanner or the hand wheel of setting for the velocity of flow, utilize the bolt with the activity packing ring 5 of sleeve 1 hug closely second spacing arch 4 and fix on the lead screw that is used for adjusting the flow in the valve jointly, then insert the key hole 11 on the lock cap 7 with the magnetism key, rotatory magnetism key makes the lug on the magnetism key break away from the edge of aperture card at the macropore bottom, realizes the connection of magnetism key and tapered end 2, makes the magnetism key can drive tapered end 2 and remove. The magnetism key utilizes the principle that opposite poles attracted to each other to make magnetism post 9 be close to the magnetism key and remove and then retract in the through-hole, place lock cap 7 on sleeve 1, rotatory magnetism key makes the lug on the magnetism key aim at the aperture then extracts the magnetism key, magnetism post 9 utilizes the principle that like poles repel each other to keep away from each other this moment, and then stretches out in the through-hole, magnetism post 9 card is in the below of first spacing arch 3, fix tapered end 2 on sleeve 1, realize the sealed of the lead screw on the valve. Because the diameter of the movable gasket 5 is smaller than that of the sleeve 1, the movable gasket 5 cannot be driven to rotate by rotating the sleeve 1, and the locking of the opening and closing state of the valve is realized.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
