Description
The utility model relates to the valve and the lockset of special construction, is that a kind of oil tank exports antitheft valve.
The control valve of draining the oil has almost all been installed in the various oil tank outlets in present domestic oil field, and wherein major part is a gate valve.Because most of oil tank is unmanned in the open air, and is stolen in order to prevent oil plant, mix padlock with chain lock or thick chain usually, valve handle is pinned.Yet the lawless person still can be sawed-off chain, or a lock opens, as usual stolen.The valve and the cipher lock that have are made of one, though not too easily by sawed-off or destruction, experienced lawless person still might break a code with feel, and lock is opened stolen.Also because the general more complicated all of the structure of cipher lock, cost is higher, also has influence on large-scale popularization and uses.Patent documentation by retrieval, the antitheft valve of occasion special uses such as well mouth of oil well, oil tank outlet is existing several, has his own strong points, and shortcoming is also respectively arranged, and is all unsatisfactory, and also large-scale popularization is used not too easily.
In view of the above-mentioned shortcoming and defect part of prior art, a kind of structure is unusual with regard to being to provide for the purpose of this utility model, anti-destruction and theftproof performance is better, cost is lower oil tank export antitheft valve, prevents that more effectively the lawless person is from the oil tank stolen.
Above-mentioned purpose is realized by following technical proposals:
This oil tank exports antitheft valve and is made up of valve casing assembly, Spool assembly, block of valve assembly and private key.It is characterized in that the valve casing assembly is the three-way pipe shape, block of valve assembly is contained in valve casing straight-through tube one port inner chamber by block of valve fixed base.Spool assembly is contained in valve casing straight-through tube inner chamber, and its spool screw rod is fixed on the interior edge face of lock core, and its spool is contained on the spool screw rod by plate.The other end of valve casing straight-through tube is a filler opening, and the bypass mouth of pipe of valve casing is an oil outlet.Put into the hydraulic fluid port ring flat-plate in the filler opening of valve casing straight-through tube, adorn flange plate outward.The bypass tube vertical welding is received on the straight-through tube.The straight-through tube inwall each side has an axial lock core slideway of square prismatic.Block of valve assembly is made up of lock housing, lock core, pressure cap, key, spring, lock bolt rod, lock pin and steel ball.Pressure cap and key are contained on the cylindrical of lock housing.Lock core is contained in the inner chamber of lock housing.8 springs and 8 lock bolt rods are contained in 8 uniform axial blind holes of lock housing.8 lock pins are contained in 8 uniform axial holes of lock core.Steel ball is filled in the annular groove at lock housing and lock core matching gap place.
Above-mentioned oil tank exports in the block of valve assembly of antitheft valve, 8 lock bolt rod length are identical or inequality, every lock bolt rod length lock pin length sum corresponding with it is all greater than the degree of depth of axial hole on the lock core, and 8 lock pins have at least one length different with other lock pin length.
The private key that above-mentioned oil tank exports antitheft valve is a disc-shape.An one end face has 8 uniform axial plugs, has at least one length different with the length of other plug in 8 plugs.The longest plug and the shortest corresponding matching of lock pin, vice-minister's plug and time short corresponding matching of lock pin,, the rest may be inferred, and the corresponding lock pin length sum that matches with it of the length of every plug all equals the degree of depth of axial hole on the lock core.There is a square plush copper that matches with the socket wrench square hole at another end face center of key.
This antitheft valve is according to different applications, can install to after the valve of oil tank outlet by flange plate or alternate manner, and original control valve still keeps use because of having withstand voltage properties and sealability.Anti-theft bolt, nut or the bolt of crossing through Quenching Treatment, nut can be adopted in its joint, or weldering firmly prevents that the lawless person from dismantling stolen or destruction.
The oil tank of making according to technique scheme exports antitheft valve, and its anti-dismounting and anti-destruction are stronger, and the block of valve can not be decrypted, and does not have private key to open, and can prevent effectively that the oil tank oil plant is stolen, also can be used for well mouth of oil well or other occasion.Also because this antitheft valve arrangement is not too complicated, and cost is lower, and working life is longer, installation and maintenance are convenient, so popularizing application prospect is preferably arranged.
