Description
Technical field
The utility model relates to a kind of explosive-source explosive post, the explosive-source explosive post of particularly a kind of mechanical type software sealing.
Background technology
Explosive-source explosive post is primarily of main charge, booster gains, plastic casing, detonator seat composition.Main charge is met and the half quick-fried or problem of miss-firing will be occurred after water, thus plastic casing and detonator seat be sealed to the key technology affecting explosive-source explosive post explosion property." GB15563-2005 explosive-source explosive post " is under the condition of 0.3Mpa at pressure, keeps 48 hours after requiring that explosive-source explosive post seals.Carry out sensitivity to initiation test after taking-up, blast completely.
At present, the sealing means of explosive column shell of seismic focus mainly contains two kinds: the PUR 1, utilizing Packing character.Glue is melted under the high temperature conditions, is filled between housing and detonator seat, reach the effect of sealing.This mode has used for many years, and Technical comparing is ripe.But along with exploring the more and more severe of environment, glued portions is easy to crack and be separated with housing, does not have sealing function.Another kind of mode is high-temperature soldering sealing.The present most of enterprise of this method adopts.Its Problems existing one is high temperature, and safety is not high; Two is there is the insecure problem of welding.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of explosive-source explosive post sealing reliable, safe mechanical type software sealing.
For solving above technical problem, the technical solution adopted in the utility model is:
A kind of explosive-source explosive post of mechanical type software sealing, comprise main charge housing and detonator seat, also comprise sealing ring and from locking closure, main charge housing forward end is provided with annular reverse lock and extends to form forward one section of external thread part, detonator seat loads main charge enclosure interior from external thread part openend, detonator seat contacts with threaded portion front end face and establishes sealing ring on the contact surface, self-locking cover gab end is provided with annular reverse lock and is connected with reverse lock of main charge housing forward end, has internal thread to be connected with threaded portion from locking closure inside.
Design of the present utility model is between main charge housing and detonator seat, increase the sealing gasket that soft material makes, and utilizes the cooperation between them to serve sealing function.And load onto from locking closure after detonator seat press-in main charge housing, reverse lock is increased in the connection of locking closure and main charge housing, further enhance sealing, meet the sealing of product at elevated pressures, also prevent coming off of sealing ring, meet in salt-soda soil, in deep-sea, the seismic prospecting of high pressure and deep well, in use achieves good effect.
What the utility model adopted is mechanical type software sealing means, compared with prior art, is guaranteeing to seal the potential safety hazard simultaneously overcoming high-temperature operation reliably.Its product structure is simple, reasonable in design, in assembling process, only adopts simple frock, with special production line, need not decrease artificial, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-main charge housing, 2-detonator seat, 3-sealing ring, 4-from locking closure, the reverse lock of 5-, 6-threaded portion.
Detailed description of the invention
In order to make those skilled in the art understand the utility model better, below in conjunction with accompanying drawing, clear, complete description is done to the technical solution of the utility model.
The explosive-source explosive post of the mechanical type software sealing shown in Fig. 1, comprise main charge housing 1 and detonator seat 2, it is characterized in that: also comprise sealing ring 3 and from locking closure 4, main charge housing 1 front end is provided with annular reverse lock 5 and extends to form forward one section of external thread part 6, detonator seat 2 loads main charge housing 1 from external thread part 6 openend inner, detonator seat 2 contacts with threaded portion 6 front end face and establishes sealing ring 3 on the contact surface, be provided with annular reverse lock 5 from locking closure 4 openend to be connected with the reverse lock 5 of main charge housing 1 front end, reverse lock 5 is buckle structures, internal thread is had to be connected with threaded portion from locking closure 4 inside.
First main charge is poured in main charge housing 1, then detonator seat 2 and sealing ring 3 are together pressed into main charge housing 1 together with primary explosive column, then screw in from locking closure 4, complete assembling.
This structure is applied to all size of explosive-source explosive post and all kinds.Explosive-source explosive post diameter is from Ф 45mm to Ф 85mm, and main charge all can adopt this structure from aqueous gels, emulsion, AN-TNT containing explosive etc.
It should be noted that the claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have various deformation and change, and all any amendment, improvement and equivalent replacements done within the utility model design and principle all should be included within protection domain of the present utility model.
