Description
Technical field
The utility model belongs to bursting work field, and in particular to a kind of waterproof safety detonating primer.
Background technology
Perforating oil gas well operation, the mining of geology underground, all bursting works of surface blasting apply it is quick-fried during, detonating primer
It is one of the link of most critical, not reliable and stable detonating primer just cannot achieve smooth propagation of explosion explosion energy, entire explosion system
System just will appear disconnected quick-fried, phenomenon of miss-firing, and cause to apply quick-fried operation failure or accident.On only being held using safe and reliable detonating primer
Transmission explosion energy under opening, it is all apply it is quick-fried during moderate heat workpiece perforating bullet, synergy powder column, primacord, secondary initiation device,
Pack etc. could obtain initiation energy and be detonated, induced detonation, play its explosion efficiency.
Existing detonating primer squeezes explosive using sealing foot pad and blocks, and under high temperature and high pressure environment, sealing foot pad holds
It is vulnerable, it may appear that the case where leak, infiltration, operation of detonating under exposed moist, underwater liquid is cannot achieve, once it is existing leakage occur
As quick-fried network is applied in entire detonation to fail；It closes up to clamp using machinery when existing detonating primer is connected with primacord simultaneously and carry out
External force squeezes clamping, and clamping force is excessive, is easy that detonating primer is made to deform, and no matter has any deformation, can all propagation of explosion be caused to fail, also held
Easily primacord is made compressional fault occur and cause disconnected quick-fried, clamping force is too small, then can cause to connect unstable, is easy to disengage.
Utility model content
The purpose of this utility model is to provide a kind of waterproof safety detonating primer, and to solve existing detonating primer, sealing performance is not good
And the problem that safety is bad.
The technical solution of the utility model is：A kind of waterproof safety detonating primer, including main booster cup and closure shell,
Main booster cup upper end, which is equipped with, blocks shell, and the closure shell lower end closed, upper end opening block on shell lower end outside wall
Lower groove equipped with annular, lower groove is interior to be equipped with high temperature resistant O-ring, blocks case inside wall and is equipped with annular protrusion, convex annular
It rises and is adapted with the card slot on primacord.
As further improvement of the utility model, the upper groove that shell upper end lateral wall is equipped with annular, fovea superior are blocked
Adhesive layer is equipped in slot.
As further improvement of the utility model, the blind end for blocking shell is raised spherical shape.Be conducive to
Block explosive.
The principles of the present invention are：Unified using inside and outside diameter, the non-ferrous metal shell of uniform wall thickness is as main detonating primer
Shell is carrier, and under vacuum, directly by the weighing of heat temperature resistant safe explosive, with particular manufacturing craft, filling is pressed into main detonating primer by several times
In shell, the mode that limit is loaded so both ensure that booster-cup charge height, degree of packing, in turn ensure that powder charge is dissipated without dust
It falls, finally the closure shell with specific purpose tool by side with "O"-ring and equipped with adhesive layer is pressed into main booster cup, securely and reliably
By the effective sealing blocking of high temperature resistant explosive, material is thus formed a safe detonating primers of complete new waterproof.
The utility model has the advantages that：
（1）The utility model waterproof safety detonating primer is entirely a set of separate unit that pressure resistance is fully sealed, even if positive
It applies quick-fried network and leakage phenomenon occurs, priming device can keep its good detonation performance.
（2）The utility model waterproof safety detonating primer is to be sealed completely using mechanical periphery O-ring, and heatproof is up to
180 degree, no seepage and no leakage, favorable sealing property；Broader practice range is widened.
（3）It blocks case inside wall and is equipped with annular protrusion, connect primacord straight cutting and enter, automatic lockout, it is not easy to is de-
Fall, avoid closed up when pincers squeeze clamping to detonating primer and primacord using machinery occur due to firmly inaccurate propagation of explosion failure or
Unstable situation is connected, the primacord of junction will not be caused compressional fault phenomenon occur and cause quick-fried rope from tomography
It is disconnected quick-fried.Make execute-in-place more efficient, connection is relatively reliable.
（4）Coordinated using the main detonating primer shell and closure shell mechanical connection of material of the same race, no matter in cold and hot ring
Under the conditions of border, contraction, dilatancy are consistent, and seal clearance is stablized, and sealing effect is good.
Be applicable to it is all apply quick-fried system, especially itself is closed in a bare condition, not moisture-sensitive water breakthrough moisture fail, fit
Be suitable under all pipes transmission liquid, underground, exposed blasting circuit.Exposed, underwater, hectic fever environment is applicable, even if under water
Environment still maintains good seal and propagation of explosion ability.
