Detailed Description

The embodiments of the invention will be described in detail below with reference to fig. 1 to 3, but the invention can be implemented in many different ways as defined and covered by the claims.

Referring to the attached drawings 1 to 3, the utility model provides a locking device for a hand wheel of a wellhead valve, which comprises a hand wheel 9, a lead screw 14, a copper bush 13, a locking nut 12 and a copper bush support 10, wherein the copper bush 13 is fastened inside the copper bush support 10 by the locking nut 12, the copper bush 13 is in threaded fit with the lead screw 14, the copper bush 13 is matched with the hand wheel 9 through a key 11, a U-shaped groove 8 is formed in the middle of the hand wheel 9, an L-shaped guard plate 1 is fixedly arranged inside the U-shaped groove 8, a sliding block 6 is movably arranged inside the U-shaped groove 8, and the sliding block 6 is simultaneously arranged on the upper end surface of the copper bush support 10; the bottom of the sliding block 6 is provided with an inclined opening, the upper part of the copper bush bracket 10 is provided with an inclined groove 3, and the inclined groove 3 can be embedded into the sliding block 6 after the sliding block moves; the side of the sliding block 6 is fixedly connected with a pull rod 2, the bottom surface of the chute 3 of the copper sleeve support 10 is longitudinally provided with a through hole 4 which penetrates through the copper sleeve support 10, and the through hole 4 can enable a needle rod type tool to act on the bottom surface of the sliding block 6 after the needle rod type tool extends into the through hole.

According to the structure of this embodiment, can know, when pull rod 2 pulling slider 6, slider 6 can imbed the inside of chute 3 of copper sheathing support 10 to the relative displacement of restriction hand wheel 9 and copper sheathing 13, because copper sheathing 13 fastening is in the inside of copper sheathing support 10, therefore hand wheel 9 is just unable the rotation after slider 6 imbeds chute 3, because the existence of L shape backplate 1, make non-working personnel unable removal slider 6, thereby reach the purpose that prevents the valve and be stolen, and the staff is using needle bar class instrument to stretch into through-hole 4, this instrument acts on the bottom surface of slider 6, can be ejecting with slider 6, thereby relieve the locking for hand wheel 9.

Preferably, when the locking hand wheel 9 is not needed, the sliding block 6 does not need to enter the chute 3, therefore, the pull rod 2 can be sleeved with the compression spring 5, so that one end of the compression spring 5 acts on the side surface of the sliding block 6, the other end acts on the inner side surface of the L-shaped protection plate 1, and when the locking hand wheel 9 is not needed, the sliding block 6 is far away from the chute 3 under the action of the compression spring 5.

Preferably, the bottom surface of the L-shaped guard plate 1 is fixedly provided with a spring piece 7, the bottom of the spring piece 7 acts on the upper surface of the sliding block 6, when the hand wheel 9 needs to be locked, when the sliding block 6 is pulled by the pull rod 2 to pass through the chute 3, the sliding block 6 can rapidly enter the chute 3 under the action of the spring piece 7, and the locking of the hand wheel 9 is realized.

The utility model discloses a creatively uses the mode of locking hand wheel 9 at copper sheathing support 10 to realize the effective protection of valve, and the staff only needs to push up slider 6 and can relieve the locking, and to other personnel who do not train or unauthorized before the post, uses current operating mode can't open the valve.

The utility model discloses a following notice has in the practical application process: namely, the utility model locks the hand wheel 9 under the condition that the valve is completely closed.

The above only is the preferred embodiment of the utility model discloses, is not used for limiting the utility model discloses, to the technical personnel in this field, the utility model discloses can have multiple change and change, all according to the utility model discloses any modification, the equivalent transform etc. that technical scheme was done, the effect of its function and production does not surpass the utility model discloses a technical scheme's scope is all regarded as the utility model discloses a protection scope.
