Abstract
The utility model discloses a butterfly valve locking device. The locking device comprises an upper pressing block and a lower pressing block which are connected through bolts, wherein a lower axial trough is formed at the bottom of the upper pressing block; an upper axial trough is formed at the top of the lower pressing block; an accommodating cavity is formed between the upper and the lower axial troughs; and a pressure plate is fixed at the top of the upper pressing block through bolts. The butterfly valve locking device is simple in structure, can be fixed on a butterfly valve through adjusting the bolts conveniently, and is used for locking a handwheel of the butterfly valve and preventing the handwheel from accidental maloperations, thereby ensuring the normal operation of the system.
Description
Technical field
The utility model relates to a kind of Locking Device, particularly a kind of butterfly valve Locking Device.
Background technique
Butterfly valve is meant that closure member (flap or butterfly plate) is a disk, rotates a kind of valve that reaches open and close around valve shaft, and main rising cut off and throttling usefulness on pipeline.The handwheel that it generally comprises valve body, gear-box and is used for the opening and closing butterfly valve.But when usual the use, the handwheel of butterfly valve is in free state, malfunction takes place easily cause serious consequence.
The model utility content
In order to solve the above problems, the purpose of this utility model is to provide a kind of Locking Device that can effectively prevent the malfunction of butterfly valve handwheel simple in structure.
The technological scheme that the invention for solving the technical problem adopted is:
A kind of butterfly valve Locking Device, comprise the upper holder block and the lower lock block that are linked together by bolt, described upper holder block bottom is provided with down axial trough, and described lower lock block top is provided with axial trough, form receiving cavity between described axial trough down and the last axial trough, there is pressing plate at described upper holder block top by bolt.
As improvement of the technical scheme, described axial trough down, last axial trough is provided with toothing.
As further improvement in the technical proposal, described spiral shell inspection is interior hexagon bolt.
The beneficial effects of the utility model are: butterfly valve Locking Device of the present utility model is simple in structure, can conveniently be fixed on the butterfly valve by regulating bolt, and the handwheel in order to the locking butterfly valve prevents its unexpected malfunction, thereby can guarantee that system normally moves.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model upper holder block structural representation;
Fig. 2 is the utility model lower lock block structural representation;
Fig. 3 is the utility model pressure plate structure schematic representation;
Fig. 4 is a user mode schematic representation of the present utility model.
Embodiment
Referring to figs. 1 through Fig. 4, a kind of butterfly valve Locking Device of the present utility model, comprise by bolt 3,4 upper holder blocks that link together 1 and lower lock block 2, described upper holder block 1 bottom is provided with down axial trough 11, described lower lock block 2 tops are provided with axial trough 12, form receiving cavity 13 between described axial trough 11 down and the last axial trough 12, and described upper holder block 1 top is fixed with pressing plate 6 by bolt 5.Upper holder block 1 of the present utility model and lower lock block 2 usefulness bolts 3,4 connect, be installed in fixed-site that pressing plate 6 can press close to butterfly valve gear-box 8 on butterfly valve hand wheel shaft 7, make hand wheel shaft 7 be arranged in receiving cavity 13, utilize pressing plate spacing above gear-box 8, hysteresis tights a bolt 3, after 4 and 5, reach the pinning handwheel, prevent the purpose of malfunction, when needing adjusting handle, unclamp connecting bolt 3,4 and get final product.Butterfly valve Locking Device of the present utility model is simple in structure, can conveniently be fixed on the butterfly valve by regulating bolt, and the handwheel in order to the locking butterfly valve prevents its unexpected malfunction, thereby can guarantee that system normally moves.
As preferred implementation, described axial trough 11 down, last axial trough 12 is provided with toothing, can increase coupling mechanism force, improves effect of the present utility model.
As preferred implementation, described bolt 3,4,5 is an interior hexagon bolt easy to use.
In addition, briquetting material of the present utility model is a duralumin, and aluminium has favorable mechanical performance, intensity and is convenient to processing greatly again, and density is little, can alleviate the weight of butterfly valve Locking Device.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
