The purpose of this utility model promptly is to provide a kind of antitheft control valve, and it allows common people can't touch keying easily by built-in control piece device design, and must be by proprietary switch member, to reach safe and antitheft function.
The utility model can be reached the antitheft control valve of above-mentioned model utility purpose, includes: a ball valve, a drain pan, a control piece, a sleeve and a shell; This ball valve is provided with a valve rod, and this valve rod is used for controlling the keying of ball valve: be provided with a guide ring around this valve rod, this guide ring one end is provided with a block; This drain pan is arranged on the guide ring outside, and is snapped on the block with breach; This control piece is to lock on valve rod with bolt, is provided with a sealing cover plate on bolt top, and solid bottom is limited between this guide ring and the drain pan; This control piece bottom is provided with a restriction opening, cooperates block can limit the rotation angle of valve rod; The top of this control piece then is provided with a jack, and is provided with an actuation slot at least around this jack, and this sleeve is the upper end that holds at control piece, and this shell then cover cap must be dashed forward this sleeve and worn shell in the outside of drain pan, control piece, sleeve; This lower cartridge also has a chassis, and in shell, and this shell also fastens block with breach with the restriction sleeve, and this shell and drain pan are sticked together.
See also the detailed description and the accompanying drawing thereof of following relevant the utility model one preferred embodiment, can further understand technology contents of the present utility model and purpose effect thereof; Relevant this embodiment's accompanying drawing is:
Fig. 1 is the end face isometric exploded view of the antitheft control valve of the utility model:
Fig. 2 is the three-dimensional assembled view of this antitheft control valve;
Fig. 3 is a schematic representation before the control piece of this antitheft control valve inserts;
Fig. 4 is that the control piece of this antitheft control valve inserts the back schematic representation; And
Fig. 5 is the control piece operational illustrations of this antitheft control valve.
See also Fig. 1, Fig. 2, antitheft control valve provided by the utility model mainly includes: a ball valve 1, a drain pan 2, a control piece 3, a sleeve 4 and a shell 5.
This ball valve 1 is provided with a valve rod 11, and this valve rod 11 is the keyings with rotating manner control ball valve 1; Be provided with a guide ring 12 around this valve rod 11, these guide ring 12 1 ends are provided with a block 13: this valve rod 11 is equipped with a hold-doun nut 14 with guide ring 12 middle locks, drops out outside the ball valve 1 to prevent valve rod 11.
This drain pan 2 is arranged on the ball valve 1 in guide ring 12 outsides, and it is provided with breach 21 with respect to block 13, and this breach 21 is snapped on the block 13, guarantees the stable of this drain pan 2; These control piece 3 bottoms are limited between this guide ring 12 and the drain pan 2, and with bolt 31 with 3 lockings of this control piece on valve rod 11, make this control piece 3 can be used to drive valve rod 11 and rotate, being provided with a sealing cover plate 32. has the attempt that unscrews bolt 31 on these bolt 31 tops to prevent other people; This control piece 3 also is provided with a restriction opening 33 in the bottom, cooperate block 13 can limit the rotation angle of valve rod 11: to be provided with a jack 34 on the top of this control piece 3, this jack 34 is to be used for ccontaining switch member described later 6, and around this jack 34, be provided with an actuation slot 35 at least, this switch member 6 must be snapped in can drive control piece 3 rotations in the actuation slot 35, performance safety opens and closes function.
This sleeve 4 is the upper ends that hold at control piece 3, being used for guiding this switch member 6 inserts in the jack 34, these sleeve 4 bottoms also have a chassis 41: 5 cover caps of this shell are in the outside of drain pan 2, control piece 3, sleeve 4, this sleeve 4 is dashed forward wear shell 5, and sleeve 4 is limited in the shell 5 with this chassis 41; And these shell 5 bottoms are provided with a breach 51, and this breach 51 also is used for fastening block 13, stablizing the setting of this shell 5, and this shell 5 are sticked together with drain pan 2.
