Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of antitheft ball valve.
Background technique
At oil field shaft mouth, oil tank, gathering station and oil and gas pipes system, petroleum chemical industry extensive use ball valve, people are usually being provided with ball valve such valve controlling liquid and gas flow, and these ball valve majorities can freely openable.For the needs to management, the ball valve of some position is forbidden arbitrarily opening and is closed, as the total lock of pipeline etc., need on ball valve, have locking device with prevent other people without authorization the breakdown valve steal draining gas.
For this reason, various Ball Valve With Locks arise at the historic moment, and its working principle is roughly the same, promptly the valve rod in the valve is locked by lockset, and then the keying of control valve.As the patent No. is that the Chinese utility model patent " Ball Valve With Lock " (notification number is CN2430586Y) of ZL00241533.X is exactly that valve rod is carried out structural change, offer groove or shrinkage pool thereon, enter or withdraw from therebetween by lock pin or lock core, thereby reach the locking or the purpose of unblanking; But because valve rod is rotating in use, and because the wearing and tearing after the tolerance of assembling or long-time the use, groove when closing on it or shrinkage pool are just not necessarily all the time towards the direction of initial setting, thereby can't realize locking fast and accurately, and groove on the valve rod or shrinkage pool processing have also increased certain technology difficulty and manufacture cost.
In addition, the locking structure of present many ball valves adopt unidirectional screens mode (promptly along valve body axially or along valve body vertically to), as Chinese utility model patent " but encryption lock ball valve " (patent No. is ZL200520144165.2) and Chinese utility model patent " novel Ball Valve With Lock " (patent No. is ZL03228287.7) promptly is to adopt in the vertical side direction of valve body respectively or the axial side direction is provided with the pellet shot from a slingshot hole or locating stud comes uniaxially to prevent the valve rod action, the handle that promptly connects valve rod can not rotate or radially pull up when valve body is closed vertically, thereby plays the purpose of locking ball valve.But, the person that illegally do not enable of ball valve many times tends to take variety of way and means to destroy locking structure, the lock mode of unidirectional screens structure may be pried open by handle when being subjected to the collapsing force of a plurality of directions easily, ball valve is opened, therefore await further to improve, to improve theftproof performance.
The model utility content
Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of can realize stem shaft to the antitheft ball valve of locking radial.
Another technical problem to be solved in the utility model is to provide a kind of antitheft ball valve that does not change stem structure and can lock the handle of ball valve at above-mentioned prior art present situation.

One is arranged on the valve rod in the described axis hole, and its two ends connect spherical valve core and handle respectively, and drives the spherical valve core rotation under handle rotates;
It is characterized in that: described protruding neck radially is projected with a boss, offer first blind hole of an axis and axis hole parallel axes at the axial end of boss, on the radial flange face of boss, offer an axis and axis hole axis, the first blind hole axis orthogonal second blind hole respectively;
Handle offers three blind hole corresponding with described first blind hole and four blind hole corresponding with second blind hole at corresponding position;
Be under valve closing or the opening state at handle, described first blind hole and the 3rd blind hole be to directly, and described second blind hole and the 4th blind hole are to directly;
Be provided with the magnetic pin in described first blind hole or the 3rd blind hole and make the spring that stretches out this blind hole trend outside the magnetic pin outer end;
Be provided with the magnetic pin in described second blind hole or the 4th blind hole and make the spring that stretches out this blind hole trend outside the magnetic pin outer end.
Described boss is fan-shaped, have first side elevation, second side elevation, for ball valve, its valve rod just in time turns over 90 ° from full-gear to closed condition, therefore when valve closing, can make described magnetic pin aim at described magnetic pin-and-hole and insertion quickly and accurately, described intracavity of handle is provided with at handle and is in the corresponding respectively first spacing stopper, the second spacing stopper that offsets with first side elevation, second side elevation under valve closing or the opening state, and this spacing stopper can limit the positive and negative rotation of handle in 90 ° of scopes.
In order to make sealing effect better, described valve rod can be arranged with the O RunddichtringO, and the Placement of valve rod and handle and spool can be utilized the various schemes of prior art, the upper end and the handle of valve rod can be fastenedly connected and fix with lead sealing by a screw simply, the lower end of valve rod is connected with the fluting close-fitting of opening on spherical valve core, and handle with sleeve is promptly realized the opening and closing to spool.
For can with realize and being connected of other valve bodies that described valve body also connects a joint at axially open, the Placement of this joint can adopt existing various technology, as the flange connection, be threaded or cutting ferrule connection etc.
Compared with prior art, advantage of the present utility model is: by setting up a boss at the vertical axis hole of valve body, the hole of axially and radially offering mutual correspondence at boss and handle, and realize spacing fixing by spring and magnetic pin structure, promptly after ball valve is closed, can realize the two-way screens of handle, the user must just can open the valve of locking by special strong magnetic switch instrument, otherwise can only destroy ball valve, strengthen the ball valve anti-theft feature.In addition, avoided valve rod is carried out specific structure of modification, handle and boss adopt cover to join rotation and realize installing and fixing, and be not only easy to assembly, and low cost of manufacture.
