Description
Technical field
The utility model relates to valve technology field, relates to a kind of Anti-theft ball valve or rather.
Background technique
Ball valve applies product very widely in pipe-line system, particularly in the fields such as residential building water supply, air feed, heating, apply more a kind of product, in order to strengthen the reasonable management to gas pipeline and water supply pipe user, when user in use breaks down, professional person is not before investigating thoroughly failure cause, in order to safety must cut off reliably the resource of confession, so need to cause unnecessary accident to occur with locking device to prevent other people from arbitrarily opening without authorization on ball valve.In addition, the handle of current ball valve be substantially all 90 ° of rotations to realize switch, so comparatively by the restriction of mounting point, ball valve is installed dumb.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of Anti-theft ball valve, and the handle capable of being of this Anti-theft ball valve rotates within the scope of 180 °, two-wayly can realize switch, installs comparatively flexible, and two-wayly can realize anti-theft locking, brings convenience to the use of user.
Technical solution of the present utility model is, provides a kind of Anti-theft ball valve with following structure, comprises valve body, spool, valve rod and handle; Described spool is located in described valve body; Described valve body is provided with the convex neck of hollow; Described valve rod is located in described convex neck, and the lower end of this valve rod is connected with spool, and the upper end of this valve rod is connected with described handle; The lower surface of described handle is provided with curve bath, and the upper-end surface of described convex neck is provided with limited post; Described limited post is contained in described curve bath, and described curve bath is 180 °; Two-way locking device is provided with between described handle and convex neck.
After adopting above structure, Anti-theft ball valve of the present utility model, compared with prior art, has the following advantages:
Curve bath due to the utility model Anti-theft ball valve is 180 °, and handle can rotate within the scope of 180 °, therefore two-wayly can realize switch, installs and is not subject to the spacing of position, and ball valve is installed more flexible.Be provided with two-way locking device between handle and convex neck, this two-way locking device makes that ball valve is two-way can realize anti-theft locking, offers convenience to the use of user.
Improve as one of the present utility model, the through hole that described two-way locking device comprises lock screw, the confession lock screw be located on handle is passed through and the locking screw thread hole be located on the upper-end surface of described convex neck; Described locking screw thread hole is provided with two, the position that the upper-end surface of being located at described convex neck symmetrically, these two locking screw thread holes is corresponding with described through hole.After adopting this kind of structure, locking device structure is simple, the position that the upper-end surface of being located at convex neck symmetrically, two locking screw thread holes is corresponding with through hole, like this, no matter rotatable handle can locking handle in which side of valve body, during locking, through hole aligns with one of them locking screw thread hole, lock screw is through through hole, and screw screw portion screws and is locked in locking screw thread hole, easy to operate.
Improve as another kind of the present utility model, described through hole is shoulder hole, and the aperture of the macropore of this through hole is greater than the diameter of the nut of described lock screw; The aperture of the aperture of this through hole is greater than the diameter of the screw rod of described lock screw and is less than the diameter of the nut of described lock screw.After adopting this kind of structure, described shoulder hole has spacing effect to described lock screw, in order to avoid lock screw rotates excessive during operation.
