Abstract
The utility model discloses an anti-theft valve with a magnetic card lock, which is used in pipelines for transporting oil, gas, water, etc. and has the structure disclosed in figure 1. The functions of a valve and a magnetic card lock are combined by a protective hood 5, and the moving motion of a lock-tongue 13 is controlled by the magnetic card lock. When a dummy club 21 of the protective cover 5 is clamped, a valve rod 3 is in the closed state of the protective cover 5, and therefore, the valve rod can not be rotated, and stealing behaviors are effectively prevented. The utility model has novel and simple structure; because the magnetic card lock can be opened only by a magnetic card with ciphers, the safety and the reliability are higher; the utility model can be installed and used in pipelines which need preventing from being stolen in industry.
Description
The utility model relates to a kind of magnetic card lock valve, and the valve that especially relates on the pipelines such as being installed in oil transportation, gas, water is to prevent that private opening, pilferage from having the valve of magnetic card lock.
We know, currently on pipelines such as oil transportation, gas, water valve are housed all, are used for opening or blinding off a line.Because valve is arranged on the outside sometimes, thereby has caused difficulty to management, private opening is often arranged, steal the generation of phenomenons such as oil, gas, water.And the manager commonly takes the flange of valve is removed, or covers with iron flask, locks a helpless measure such as lock, but often produces little effect, and has caused harm to national wealth and safety.
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of on the basis of original valve, is provided with the structure of pinning valve, promptly should design the pilot line function of existing valve, the effect that can have lock again is to reach the purpose that prevents pilferage.
For achieving the above object, the technical solution adopted in the utility model is on valve body, valve rod and the magnetic card lock technical foundation at original valve, to be provided with a safety cover structure.Safety cover utilizes the spring flexible, and can rotate, and is opened and closed by magnetic card lock control.When throttle down, safety cover with valve rod cover in housing, reached can't private opening purpose, thereby finish the design.
Now in conjunction with the accompanying drawings, details are as follows to embodiment of the present utility model:
Accompanying drawing 1: magnetic card lock valve mechanism schematic representation.
Accompanying drawing 2: magnetic card lock valve A-A cross-sectional schematic.
Accompanying drawing 3: magnetic card lock valve B-B cross-sectional schematic.
Structure of the present utility model is shown in accompanying drawing 1,2,3: be connected with valve rod 3 on valve body 1, link 2 is connected with valve rod 3 by screw thread, link 2 is connected with frame 12 by screw 17 again, lock core body 6 is housed in frame 12, lock core body 6 by last core body 18 and following core body 19 form 5 one-tenth hollow cylindrical of safety cover; The lower end is provided with boss 21, and is provided with two symmetrical square holes 20 in the above; Safety cover 5 is inserted in link 2, and its boss 21 rests on the shoulder frame in the frame 12, and thrust spring 4 also rests on the boss 21 of safety cover 5 with said method; Last core body 18 is provided with the slide block 7 of tongue 13 with lock, on slide block 7, have some apertures, locking plate 8 is arranged on slide block 7 again, have too on locking plate 8 and slide block corresponding aperture about in the of 7, some magnet steel 16 are set in the part aperture of slide block 7, minor flaps 9 is covered on locking plate 8, the plane is provided with a hole on last core body 18, dead bolt 13 is stretched out from the hole, stretch in the frame 12, make it to lean on mutually with the boss 21 of safety cover 5; Following core body 19 is provided with spring 10, is stamped a restoring board 11 on spring 10; The gap of being made up of in lock core body 6, two core bodys last core body 18 and following core body 19 is used to insert magnetic card 15, and password on the magnetic card 15 and magnet steel 16 match; Between lock core body 6 and frame 12 thrust spring 14 being housed forms.Its working principle is: when wanting Open valve, the magnetic card 15 that will have password inserts in the gap of going up core body 18 and following core body 19, magnetic card 15 is depressed the restoring board 11 and the spring 10 of core body 19, and magnetic card 15 is pushed in it, compression thrust spring 14, because password on the magnetic card and the magnet steel 16 in slide block 7 apertures match, making part protrude in magnet steel 16 in the aperture gives up the throne in the aperture, driving dead bolt 13 by slide block 7 slides in frame 12, the dead bolt 13 that is about to be stuck in safety cover 5 two shoulder boss 21 moves, thereby make safety cover 5 under the effect of thrust spring 4, safety cover 5 outwards ejects, and boss 21 and the shoulder frame in the frame 12 are put mutually, rotate safety cover 5 then, make in two square holes 20 valve rod 3 to occur, can use the instrument Open valve, make pipeline unimpeded; In the time will closing, go up between core body 18 and the following core body 19 restoring board 11 and spring 10 under the compression on the core body 19 with magnetic card 15 insertions; make thrust spring 14 effects, the slide block 7 that has dead bolt 13 is moved, press safety cover 5 with hand push simultaneously; compression thrust spring 4; dead bolt 13 blocks the boss 21 of safety cover 5, transfers to magnetic card 15, has just finished closing operation; because in the time of in off position; valve rod 3 is among the safety cover 5, thereby can't rotation valve rod, has played the effect of anti-pilferage.
The utility model has designed the structure of a safety cover, makes the organic combination of valve and magnetic card lock, has effectively prevented the generation of the behavior of stealing.The utility model is simple and reasonable for structure, and fool proof reliable, has use value and popularizing application prospect.
