Description
Technical field
This utility model is related to a kind of ball valve, more particularly to a kind of female thread Anti-theft-dismounting locking ball valve.
Background technology
Ball valve is to be well used valve on a kind of domestic trachea and water pipe.Ordinary ball valve is no to medium flow direction to be limited,
When mounted, any one end can be used as medium entrance and outlet.To prevent from by way of dismantling ball valve carrying out gas meter, flow meter
Adjust privately or it is premeditated damage, needs are set to preventing from stealing the structure torn open；In addition, the unification to strengthen valve opening and closing
Management, the potential safety hazard for preventing user to be turned on and off without authorization and bringing need special tool is arranged at the opening structure of valve
The lockable mechanism that tool could be opened.Lack in the market it is a kind of not only can Anti-theft-dismounting but also can locking product.For this reason, it may be necessary to develop
A kind of Anti-theft-dismounting locking ball valve.
The content of the invention
The purpose of this utility model is for the deficiencies in the prior art, there is provided a kind of female thread Anti-theft-dismounting locking ball valve, should
Ball valve forms Anti-theft-dismounting protection so as to lock outside loose joint nut by lockable mechanism is arranged between valve rod and valve body
The only ball valve with Anti-theft-dismounting function, to meet market demands, and simple structure, low cost of manufacture.
To realize object defined above, this utility model is adopted the following technical scheme that.
A kind of female thread Anti-theft-dismounting locking ball valve, including valve body, valve seat, ball valve core, valve rod, valve rod free end is connected with
Handle, the annexation of ball valve core, valve rod and handle in linkage；Wherein, valve body import end be in internal thread interface form, valve body
The port of export is screwed with the joint for constituting valve gap, and joint free end is only rotatably connected with loose joint nut by elastic spring, connects
Head has been internally formed fluid passage；Locking structure, and locking are formed with by spacer shell and lock bolt between valve rod and valve body
Screw has triangular head；The loose joint nut periphery also forms Anti-theft-dismounting knot by being covered with only rotatable antitheft outer cap
Structure.
Using this utility model of preceding solution, as between valve rod and valve body, lock bolt is formed with locking knot
Structure, and lock bolt has triangular head；To be only capable of to carry out locking or unblock to valve rod by Triangle ID spanner, it is easy to
Unified management and control, prevent the potential safety hazard that user opens without authorization and brings；In addition, lockable mechanism is formed by spacer shell,
Lock bolt is not directly pushed up or is fastened on valve rod, moves tap wrench without authorization beneficial to reduction and after reducing locking operation or locking
And bring the damage of valve rod；Meanwhile, loose joint nut periphery also forms Anti-theft-dismounting structure by being covered with only rotatable antitheft outer cap,
The loose joint nut of this valve is generally used for the facilities such as the gas meter, flow meter with user and is connected, and antitheft outer cap is enclosed in outside loose joint nut,
Traveling nut is disassembled from being connected with plate power driven tools, to reach Anti-theft-dismounting purpose.This utility model collection locking, only
Return and three kinds of functions of Anti-theft-dismounting are integrated, and simple structure, low cost of manufacture.
Preferably, the receiving locking that the locking structure is provided with by the locking section and spacer shell of lock bolt front end
The breach of section is constituted；Spacer shell cooperatively forms linkage structure by flat horizontal surface with valve rod.Locking section is arranged to into cylinder knot generally
Structure, the core diameter of thread of its diameter less than or equal to lock bolt, to guarantee that screw is free to advance or retreat；Meanwhile, spacer shell and valve rod it
Between using flat horizontal surface coordinate structure, its simple structure, easy to process, low cost of manufacture.
Preferably, on joint, antitheft outer cap is in bell shape to the antitheft outer cap movable set of the Anti-theft-dismounting structure, antitheft
Outer cap can form sealing cover by loose joint nut inner end and periphery to loose joint nut, and antitheft outer cap has the shifting of preseting length in joint
Dynamic distance, so that loose joint nut exposes outside antitheft outer cap vertically；Bullet is provided with by the first draw-in groove on the inwall of antitheft outer cap
Spring collar, engaging in the second draw-in groove for receiving the spring collar, second draw-in groove is formed with loose joint nut outer wall easy-to-draw
De- technique collar；When the spring collar snaps in second draw-in groove, the periphery of loose joint nut is housed in antitheft outer cap
Portion.To be taken the second draw-in groove by technique collar before valve is installed, spring collar is prevented to snap in, it is ensured that loose joint nut can expose
Outside antitheft outer cap, to be connected with user's gas meter by the dynamic loose joint nut of spanner plate, after being connected, by technique collar from the
Two draw-in groove is pulled out, and is promoted antitheft outer cap to move towards loose joint nut distal end, spring collar inboard portion is fastened in the second draw-in groove,
Meanwhile, Outboard Sections are still fastened in the first draw-in groove, so that axially-movable quilt of the antitheft outer cap of system relative to loose joint nut
Limit, and sealing cover is in loose joint nut periphery, loose joint nut is sheltered from as the hexagonal portion of spanner connecting portion.
The beneficial effects of the utility model are, ball valve by lockable mechanism is arranged between valve rod and valve body, in loose joint spiral shell
Female outside Anti-theft-dismounting that formed is protected so as to the ball valve with locking and Anti-theft-dismounting function, can fully meet market demands, and structure
Simply, low cost of manufacture.
