Description

The magnetic control valve for guarding against theft

Technical field

The invention belongs to special valve, be mainly used in the various pipelines, oil well mouth and the other field that need lock control, being specially adapted to that physical environment is abominable, anti-damage performance requirement height, can't (or not allowing) using automatically controlled, the demanding occasion of confidentiality, is a kind of magnetic control valve for guarding against theft specifically.

Background technique

Mainly based on mechanical ball valve and board-like gate valve, they are bringing into play important effect to existing valve in the every field of national economy, for example pipeline valve of the head valve in oil field, oil transportation (gas) or the like.But all valves all are valves of free switch, just say, no matter under any circumstance, when people need switch valve, but the handle of regulated at will valve just can be finished.But in many special environment, valve does not allow any adjusting (being forbidden without permission to touch), and must take reliable measure that valve is protected.

For example: the valve on many critical pipings of the oil transport pipeline in oil field, gas pipeline, chemical industry unit just often needs strictly to control, pins reliably, and common practices is to adopt conventional lockset (for example: padlock etc.) add with material field welding such as wire rope, angle bar and carry out.

But under the bigger condition of possibility abominable at environment, that destroy, conventional lockset can't meet the demands, saboteur's (steal oil, gas person) can adopt general method (smash lockset, pound the handle of cutting off the hands, cut off wire rope, angle bar) to destroy, and the oil that achieves the goal simply-steal, the non-ferrous metal on the valve etc. steathily.Therefore, caused great economic loss to the oil field.

For overcoming the above problems, many oil fields have taked various ways to improve anti-destructive, but all undesirable-not that way is invalid, being exactly that cost is too high can't use.If when strict fire protection requirement is arranged in Environmental Conditions again (electric power control is unallowed), and other conventional locksets can't use especially at all.

Summary of the invention

The utility model is a kind of magnetic control valve for guarding against theft that provides at the deficiencies in the prior art; performance, the function of original valve remain unchanged; lockset has enough survivabilitys; security performance is good; anti-theft is stronger, can protect leading screw, pressure mother and the copper sheathing of valve reliably, need not control by electric power; switch is simple, easy operating and on-the-spot the installation.

The technical solution of the utility model is: a kind of magnetic control valve for guarding against theft, mainly comprise valve housing, leading screw and be enclosed within the parts that reverse on the leading screw, it is characterized in that special-purpose lock cover of described valve configurations and key, it is L shaped ring-type lock that described valve housing top is provided with a cross section, and lock ring-type perpendicular outer wall is provided with the dead bolt locating slot; Described lock cover is inverted tubbiness, leading screw, pressure mother, the copper sheathing of valve all can be covered, the lock cover is provided with and the corresponding dead bolt mounting groove of dead bolt locating slot near the inwall at place, lower edge, the dead bolt that has magnet is installed in the dead bolt mounting groove, the dead bolt middle part is provided with the guide ring of projection, one tapered spring is arranged in the dead bolt mounting groove, and the thin end of spring withstands on the dead bolt guide ring, and outer wall is provided with the ring-type locating slot of key around the lock cover bottom; Described key is the annular magnetic control key in the ring-type locating slot that can be enclosed within lock cover bottom, arranges according to the magnetic coding of magnet on the dead bolt, and magnet corresponding one by one with latch bolt position and that magnetic polarity is opposite is set on the vertical inner face of magnetic control key; The described parts that reverse are the adjustment nut that is enclosed within on the valve leading screw.

Described lock perpendicular outer wall is provided with the ring-shaped lock dead bolt locating slot and prevents to lock the keyway of cover rotation, and lock cover inwall is provided with the key body corresponding with the housing keyway.

Described lock cover is divided into up and down two-part, above a part thinner, mainly cover leading screw, below a part thicker, mainly be that pressures mother, copper sheathing are covered.

The cyclic convex edge that the outer rim setting of the horizontal anchor ring of described lock is upwards dug, lock cover lower edge leans against on the horizontal anchor ring of lock, and cyclic convex edge can block the lower edge of lock cover.In case stealer prizes the lock cover.

Described ring key is divided at least and can folds and hinged two joints.

Main inventive principle of the present utility model is: the design and manufacturing technology of valve and magnetic control technology and magnetic coding techniques are combined together, the character of utilize the same sex of magnet to repel each other, there is a natural attraction between the sexes, by special structural design, reach control (open and close) to dead bolt.Utilize the magnetic coding techniques that each dead bolt and key are carried out polarity setting (coding).When unblanking, the polarity of each magnetic pole must meet coding requirement, otherwise, can't open.Thereby overcome the conventional lockset weakness of lock control and protection valve targetedly, realized secretly putting that dead bolt, no keyhole, unregulated power are controlled, are easy to field stripping, good confidentiality, theftproof performance height, survivability is strong, switch is simple, easy operating, lower-cost requirement.Satisfy actual demand, and produced following good effect:

1, thoroughly change the present situation that original valve can't lock control, reduce cause because of destruction loss (mainly referring to valve)-this is lost in, and number is huge in each elephant of the whole nation;

2, stop to be destroyed the loss of the oil that causes, gas and because of the fire loss of the bad initiation of automatically controlled fireproof performance because of valve;

3, reduce the investment of the lock control equipment of open-air pipeline valve and marginal well valve;

4, reduce administrative staff's quantity and reduction workload, raise the management level.
