Abstract
The utility model provides an anti radial high buffering composite gasket who assaults that transships, including nonmetal broad -mouthed receptacle for holding liquid and metallic gasket, nonmetal broad -mouthed receptacle for holding liquid be oblate post, one end is opened has circular recess, open the recess bottom has the through -hole that link up the oblate post other end, the metallic gasket be haplopore ring -shaped gasket, inlay in the circular recess of nonmetal broad -mouthed receptacle for holding liquid, and closely cooperate with circular recess. The utility model discloses there is great anti high ability of transshipping impact, higher intensity, launch at the height, cast and transship under the impact, have higher security, at the high centrifugal operational reliability height under the impact that transships, and delayed precision is higher.
Description
Technical field
The invention belongs to priming system technical field, it is related to a kind of loop buffer Composition spacer, prolongs particularly to radial direction high overload
Phase ignitron composite buffering pad.
Background technology
At present, some priming systems domestic are to meet specific function to require, using high sensitivity point in its internal structure design
The design that gunpowder pad fiery with biography is fitted, and pass fiery pad and be single metallic gasket or non-metallic gasket, using point
The mode that gunpowder is fitted with metallic gasket, its anti-radial direction overload impact ability is less than 15000g；Using ignition charge and non-metallic pad
The mode of piece laminating, it can bear radial direction overload impact and be more than 25000g, but non-metallic gasket intensity is poor compared with metallic gasket.Cause
This, existing gunpowder formula extension priming system can not meet simultaneously the security that products radial can bear under high emission overload impact and
High centrifugation is transshipped lower reliable action and is had the requirement of higher delay precision.
Content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of buffering Composition spacer, requires for high impact property
Priming system design in, be both resistant to the impact of 29000g radial direction high overload, and there is the intensity of metallic gasket again, be capable of gunpowder
Reliable action under the security under high emission, impelling overload impact and high centrifugation overload for the formula extension priming system, and have higher
Delay precision.
The technical solution adopted for the present invention to solve the technical problems is：Including nonmetallic broad-mouthed receptacle for holding liquid and metallic gasket, described
Nonmetallic broad-mouthed receptacle for holding liquid is oblate post, and one end has circular groove, and bottom portion of groove has the through hole of the insertion oblate post other end；Described gold
Genus pad is single hole annular gasket, is embedded in the circular groove of nonmetallic broad-mouthed receptacle for holding liquid, and is fitted close with circular groove.
The material of described nonmetallic broad-mouthed receptacle for holding liquid is polytetrafluoroethylene (PTFE) or nylon material.
The material of described metallic gasket is steel.
The outer surface of described metallic gasket is coated with buffering paint.
Described buffering is painted as acrylic lacquer.
The invention has the beneficial effects as follows：There are larger anti high overload impact, the ability of higher-strength.In high emission, impelling
Carry under impact, have higher security；Under high centrifugation overload impact, functional reliability is high, and delay precision is higher.Through test
Show, using the structure design of buffering Composition spacer, it radially can bear positive 29000g, reverse 29000g to certain Dark Ignition pipe
Misfire after overload impact and radially centrifugation overload 300r/s, continue 2s and misfire, and radially, centrifugal rotation speed
Reliable action in the range of 50r/s～240r/s, and the extension time reach 0.34s～0.50s scope, solve gunpowder formula delay
A difficult problem for priming system reliable action and delay precision difference under the security under high emission, impelling overload and high centrifugation overload.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the present invention includes but are not limited to following enforcements
Example.
The present invention is in order to be able to meet Dark Ignition caliber to can bear high emission, the security under impelling overload impact and height
Higher delay precision under centrifugation overload, employs buffering Composition spacer design in the design of Dark Ignition tubular construction, solves
Dark Ignition pipe is subject to high overload to impact and the problem of accidental ignition in system transmitting and projecting process, improves the peace of product
Quan Xing；Reliably working and have the requirement of higher delay precision under high centrifugation overload condition.Described buffering Composition spacer by
Nonmetallic broad-mouthed receptacle for holding liquid, metallic gasket, buffering paint composition, as shown in Figure 1：
Described nonmetallic broad-mouthed receptacle for holding liquid is through-hole type cylindrical structure, and there is annular groove one end, for connecting metallic gasket, another
Hold as through hole contact surface, a biography fire action.
Described metallic gasket is single hole annular gasket, act as strengthening the intensity of Composition spacer and point passes fire.
Described buffering is painted as damp-proof paint, is coated in outer metallic surface, fixing metallic gasket position, reduces metallic gasket
Impulsive force.
As shown in FIG. 1 to 3, embodiments of the invention provide a kind of buffering Composition spacer of anti-radial direction high overload impact,
Including nonmetallic broad-mouthed receptacle for holding liquid 1, metallic gasket 2, buffering paint 3.Nonmetallic broad-mouthed receptacle for holding liquid 1 is through-hole type cylindrical structure, concave end on the cylinder
There is the cannelure of a diameter of 1.5mm.Metallic gasket 2 is single hole loop configuration.
During making, nonmetallic broad-mouthed receptacle for holding liquid, metallic gasket are sequentially placed in mould, then metallic gasket is pressed into the recessed of nonmetallic broad-mouthed receptacle for holding liquid
In groove, then apply buffering paint 3 on metallic gasket surface and sheet metal with nonmetallic broad-mouthed receptacle for holding liquid joint close.
