Description
Technical field
The present invention relates to valve field, relate to a kind of Anti-dismantling ball-valve or rather.
Background technique
In fuel gas pipeline system, general valve can only play the effect of switch, because the carelessness of people or bad intention, and may open the valve that should not open, thus bring fatal security incident for some high risk industries.For this kind of situation, current technician also have developed many Anti-dismantling ball-valves, but the Anti-dismantling ball-valve of prior art or its lock state and free switch state conversion process more loaded down with trivial details; Be exactly that structure is unreliable, do not reach tamper effect effectively.Such as, on State Intellectual Property Office's patent website, the disclosed patent No. is the utility model patent of ZL98243087.6, this utility model patent discloses a kind of technological scheme of detatching-proof cylinder valve, although this kind of cylinder valve structure be comparatively simple, it is more convenient to use, but structure is more unreliable, easily taken apart by people.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of structure simple, easy to use and can the Anti-dismantling ball-valve of effective tamper.
Technical solution of the present invention is, provides a kind of Anti-dismantling ball-valve with following structure, comprises valve body, spool, valve rod and handle; Described valve body is provided with the convex neck of hollow, and the inner chamber of described convex neck is connected with described body cavity; Described spool is located in described valve body, described valve rod is located in described convex neck, the spool described in the connection of one end of described valve rod, the handle body of handle is linked in outside the other end of valve rod, is provided with magnet automatic locking mechanism between the other end of described handle and described valve rod; Described Anti-dismantling ball-valve also comprise match with described magnet automatic locking mechanism for removing the tripper that magnet automatic locking mechanism locks;
Described tripper comprises the lid for being linked in outside described handle body, and in the both sides of described lid, relative position is provided with the receiving groove for accommodating magnet; Magnet is respectively equipped with in receiving groove described in two; The magnetic of the magnet in the receiving groove described in two is contrary;
The relative position of described handle is provided with two radial direction through hole, is respectively equipped with two magnet straight pins in the radial direction through hole described in two, 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.
After adopting above structure, Anti-dismantling ball-valve of the present invention, compared with prior art, has the following advantages:
Handle body due to Anti-dismantling ball-valve of the present invention is linked in outside the other end of described valve rod, magnet automatic locking mechanism is provided with between the other end of described handle and described valve rod, after ball valve is closed, magnet automatic locking mechanism will locking handle and valve rod, do not have tripper, user cannot open ball valve; When user needs to reopen ball valve, as long as just can easily be unlocked ball valve by tripper, make the lock state of ball valve and free switch state conversion process more convenient, and magnet automatic locking mechanism structure is comparatively reliable, effectively can play the effect of tamper.
When needing to unlock magnet automatic locking mechanism, as long as the lid of tripper is linked in outside handle, magnet straight pin in magnet difference alignment handle in lid, and magnet is contrary with the magnetic of close magnet straight pin, the magnet straight pin be 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 horizontal position higher than described groove of described magnet straight pin.
As a modification of the present invention, described magnet automatic locking mechanism comprises two grooves on the sidewall of the other end being located at described valve rod, two of being located on the sidewall of described handle can along the radial movable magnet straight pin of handle and the return spring be located between described handle and described valve stem tip; Groove described in two is located on the relative position of the sidewall of the other end of described valve rod; Contrary and the matching size of these two magnet straight pins and the groove described in two of the magnetic of the magnet straight pin described in two; 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 of structure, when needing locking ball valve, as long as pressing handle, when making the horizontal position of magnet straight pin mutually concordant with the horizontal position of described groove, by the magnet characteristic that there is a natural attraction between the sexes, two magnet straight pins will attract each other and insert in described groove respectively; Thus with regard to lockable ball valve.
Also have a kind of improvement as of the present invention, the outer end of described radial direction through hole is sealed by lead sealing.After adopting this kind of structure, not only firmly, but also antitheft effect can be played.
The other end of described valve rod is provided with boss, and the inner side of described handle is provided with radial scrobicular ring, is provided with jump ring in described radial scrobicular ring; Described jump ring is stuck on the step of described boss.
