Abstract
The utility model provides a high explosive instantaneous primer detonator, which does not contain initiating explosives. The explosive loading of the detonator is divided into three layers: a first explosive loading, transition explosive and main explosive loading. A self seal piece is arranged between a reinforced cap and the first explosive loading; the self seal piece is capable of preventing the energy dissipation of the primer, and is helpful for the control and stabilization of time. The detonator can replace general military instantaneous electric detonators, and can also be made into delayed delay detonator serial products according to requirements. The utility model is used for mining and blasting various types of engineering.
Description
The utility model belongs to and detonates or the portfire field, is specifically related to a kind of high explosive wink send out Nonel detonator.
Existing Nonel detonator (claiming non-electric ms detonator or engineering millisecond detonator again) generally all is equipped with priming explosive, and is provided with the quick-fried awl that disappears.Its weak point is owing to contain priming explosive, and is very sensitive to external irritants such as mechanical impacts, miss-fires in mining and engineering explosion process that it is very dangerous to get rid of the danger, and also is difficult in addition avoid indivedual detonators to sneak in mining, causes that accident takes place; Owing to be provided with the quick-fried awl that disappears, the energy decrement that primacord is detonated, and capsular is extended to millisecond more than the magnitude action time.
The utility model purpose is that (microsecond magnitude) Nonel detonator is sent out in design a kind of wink that does not contain priming explosive.
The utility model purpose is achieved in that the priming explosive in the cancellation detonator, powder charge is divided into three layers, i.e. first powder charge, transitional medicine and main charge, cancelled the quick-fried awl that disappears, between the strengthening cap and first powder charge, adorned one, plastic detonating tube directly has been connected with strengthening cap from mounting.
The utility model has the advantages that capsular action time is short, synchronism good, and safety in utilization is good, low cost of manufacture.
The utility model has following accompanying drawing:
Fig. 1 detonator structure synoptic diagram
Embodiment:
Powder charges in the housing 9 are divided into three layers, i.e. the preparation of first powder charge 6, transitional medicine 7 and main charge 8, the first powder charges need be handled through granularity, and its granularity control is at 80～120 orders, and adds 3～5% carbon dust.Adorn one from mounting 5 between the strengthening cap 4 and first powder charge 6, cancelled the quick-fried awl that disappears in the prior art, can prevent the primacord waste of energy like this, the control that helps the time has reached the effect of detonator weak point action time and synchronism with stable.From the thin round platform that mounting 5 is made for insulating material, outer wall and strengthening cap 4 wringing fits.Plastic catheter 1 directly is connected with strengthening cap 4.Shell 3 is connected with housing 9, and bayonet socket plug 2 is clamped in plastic detonating tube 1 in the shell 3.Primacord 1 is through causing the first charge detonates detonator from mounting 5.
If increase the delay powder section, can make the series product of the various high explosive Nonel detonator that postpones as required, the section of being used for detonation is broken, as is used for mining and various engineering explosion.
Claims (2)
1. a high explosive wink is sent out Nonel detonator, comprise plastic detonating tube (1), strengthening cap (4) and housing (9), it is characterized in that powder charge in the housing (9) is divided into three layers of first powder charge (6), transitional medicine (7) and main charges, adorn one from mounting (5) between strengthening cap (4) and first powder charge (6), plastic detonating tube (1) directly is connected with strengthening cap (4).
2. high explosive wink as claimed in claim 1 is sent out Nonel detonator, it is characterized in that the described thin round platform of making for insulating material from mounting (5), outer wall and strengthening cap (4) wringing fit.
