FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, a digital password locking ball valve comprises a valve body 1 and a valve shaft 2, wherein a password box body 3 for controlling the movement of the valve shaft 2 through password input is arranged on the valve body 1, an operating handle 4 and a number plate 5 are arranged on the upper portion of the password box body 3, an operating shaft 6, a compression spring 7, a gasket 8, a first password plectrum 9, a second password plectrum 10, a third password plectrum 11, a guide block 12, a connecting transverse cutter 13, a return spring 14, a positioning spring 15, a positioning ball 16 and a linkage sleeve 17 are arranged in the password box body 3, the operating shaft 6 is connected with the operating handle 4, the compression spring 7, the first password plectrum 9, the second password plectrum 10, the third password plectrum 11, the connecting transverse cutter 13 and the linkage sleeve 17 are sequentially arranged, a slot is formed in the first password plectrum 9, the second password plectrum 10 and the third password plectrum 11, and a slot is formed in the first password plectrum 9, the second password plectrum 10 and the slot is formed in the third password plectrum 11, Second password plectrum 10 and third password plectrum 11 form open channel through rotating adjustment fluting position, guide block 12 is located on the open channel extending direction, reset spring 14 is located third password plectrum 11 below, linkage cover 17 inboard is equipped with the mounting groove, location pearl 16 and positioning spring 15 are located in the mounting groove, be equipped with the draw-in groove on the 2 lateral walls of valve shaft, link the linkage through location pearl 16 and draw-in groove block between 17 and the valve shaft 2, fixed connection between 17 of linkage cover and the operating axis 6. Gaskets 8 are arranged between the first password poking piece 9 and the second password poking piece 10 and between the second password poking piece 10 and the third password poking piece 11.
The first password poking piece 9, the second password poking piece 10 and the third password poking piece 11 are arranged, three-digit passwords can be set, and grooves are formed in the password poking pieces to allow the guide blocks 12 to penetrate through the grooves, so that synchronous linkage of the linkage sleeve 17 is realized. The linkage sleeve 17 moves along the axial direction and is clamped and fixed with the valve shaft 2, so that the valve is further opened and closed. The compression spring 7 enables the first password poking piece 9, the second password poking piece 10, the third password poking piece 11 and each gasket 8 to be tightly matched, and the stability of the structure and the smooth action are ensured. When the valve is closed, the return spring 14 returns to separate each code poking sheet from the guide block 12, and then the code is disturbed. The positioning spring 15 makes the positioning ball 16 always have an elastic tendency in the engaging direction, which is favorable for tight fit. The design of password dish can be that the part is in password box 3, through directly pushing down hold-down spring 7 to drive moving down of other spare parts, and then reach the block linkage effect. The fixed connection between the linkage sleeve 17 and the operating shaft 6 ensures that the linkage sleeve 17 automatically separates from the valve shaft 2 to restore the original state after the operating handle 4 is pulled at the later stage.
And a plurality of layers of sealing packing 18 are arranged between the valve shaft 2 and the valve body 1, so that the sealing property and the tightness are enhanced.
The width of the groove is larger than or equal to the width of the guide block 12, so that the fault tolerance rate is improved, and the valve can be opened when the password is correctly input.
The working principle is summarized as follows: the digital password locking device of the device is directly arranged on the upper part of the valve, can be used together with various valves, and only needs managers or related operators to remember the management passwords. The password can be set according to relevant data such as valve position number and be convenient for manage, only need when needing the operation valve through input correct password, make all password plectrums aim at guide block 12, push down the password dish, make linkage cover 17 connect the upper valve drive shaft can operate the valve, only need after the operation finishes to pull up operating handle 4 and make the password locking plate reset, rotate operating handle 4 again and disturb the password dish and can realize the locking.
The valve management cost and the management difficulty which need to be locked are reduced, and the private operation of Wu operation or non-operating personnel is effectively avoided. The manager does not need to carry a large number of keys or special-shaped wrenches or magnetic wrenches, and the labor intensity of the operation and maintenance personnel is reduced.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing and simplifying the description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, are not to be considered as limiting the present invention, and that the fundamental principles, the main features, and the advantages of the present invention are shown and described above, as would be understood by those skilled in the art.
