Description

Anti-dismantling ball-valve
Technical field
The present invention relates to valve field, relate to or rather a kind of Anti-dismantling ball-valve.
Background technique
In the fuel gas pipeline system, general valve can only play the effect of switch, may be because people's carelessness or bad intention for some high risk industries, and opened the valve that should not open, thus bring fatal security incident.For this kind situation, the technician has also developed many Anti-dismantling ball-valves at present, but the Anti-dismantling ball-valve of prior art or its lock state and free switch state conversion process are more loaded down with trivial details; Be exactly that structure is unreliable, do not reach tamper effect effectively.Such as, the disclosed patent No. is the utility model patent of ZL98243087.6 on State Intellectual Property Office's patent website, this utility model patent discloses a kind of technological scheme of detatching-proof cylinder valve, although this kind cylinder valve structure is simple, use is more convenient, but structure is more unreliable, is easily taken apart by the people.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of simple in structure, the easy to use and effective Anti-dismantling ball-valve of tamper.
Technical solution of the present invention is, a kind of Anti-dismantling ball-valve with following structure is provided, and comprises valve body, spool, valve rod and handle; Described valve body is provided with the protruding neck of hollow, and the inner chamber of described protruding neck is connected with described body cavity; Described spool is located in described valve body, described valve rod is located in described protruding neck, one end of described valve rod connects described spool, and the handle body of handle is linked in outside the other end of valve rod, is provided with the magnet automatic locking mechanism between the other end of described handle and described valve rod; Described Anti-dismantling ball-valve also comprises the tripper that is used for removing the locking of magnet automatic locking mechanism that matches with described magnet automatic locking mechanism.
After adopting above structure, Anti-dismantling ball-valve of the present invention compared with prior art, has the following advantages:
Because the handle body of Anti-dismantling ball-valve of the present invention is linked in outside the other end of described valve rod, be provided with the magnet automatic locking mechanism between the other end of described handle and described valve rod, after ball valve is closed, the magnet automatic locking mechanism will locking handle and valve rod, there is no tripper, the user can't open ball valve; When the user need to reopen ball valve, as long as just can easily carry out release to ball valve by tripper, make lock state and the free switch state conversion process of ball valve more convenient, and magnet automatic locking mechanism structure is more reliable, can effectively play the effect of tamper.
As a modification of the present invention, described magnet automatic locking mechanism comprises two grooves on the sidewall of the other end of being located at described valve rod, be located on the sidewall of described handle two can along the radially movable magnet straight pin of handle and be located at described handle and described valve stem tip between return spring; Described two grooves are located on the relative position of sidewall of the other end of described valve rod; Opposite and the sizes these two magnet straight pins and described two grooves of the magnetic of described two magnet straight pins match; Under the effect of described return spring, the horizontal position of described magnet straight pin is higher than the horizontal position of described groove.After adopting this kind structure, when needing the locking ball valve, as long as press handle, when making the horizontal position of magnet straight pin mutually concordant with the horizontal position of described groove, be subjected to the magnet characteristic that there is a natural attraction between the sexes, two magnet straight pins will attract each other and insert respectively in described groove; Thereby with regard to the lockable ball valve.
As another kind of improvement the of the present invention, described tripper comprises be used to being linked in the outer lid of described handle body, and in the both sides of described lid, the relative position place is provided with the receiving groove for accommodating magnet; Be respectively equipped with magnet in described two receiving grooves; The magnetic of the magnet in described two receiving grooves is opposite.After adopting this kind structure, in the time of need to carrying out release to the magnet automatic locking mechanism, as long as the lid of tripper is linked in outside handle, magnet in lid is the interior magnet straight pin of alignment handle respectively, and magnet is opposite with the magnetic of close magnet straight pin, the magnet straight pin that is inserted in like this in described groove will be sucked out described groove, then under the effect of return spring, described handle will pop up, and makes the horizontal position of described magnet straight pin higher than the horizontal position of described groove.
Also have a kind of improvement as of the present invention, the relative position of described handle is provided with two radial direction through hole, is respectively equipped with described two magnet straight pins in described two radial direction through hole, and described magnet straight pin is slidably fitted in described radial direction through hole; The outer end of described radial direction through hole is provided with capping.Simple in structure, easily realize.
Also have a kind of improvement as of the present invention, the outer end of described radial direction through hole seals by lead sealing.After adopting this kind structure, not only firm, but also can play antitheft effect.
The other end of described valve rod is provided with boss, and the inboard of described handle is provided with radially scrobicular ring, is provided with jump ring in described radially scrobicular ring; Described jump ring is stuck on the step of described boss.
