The tubular product sample for planting specification is tested, it is impossible to meet the experiment of plurality of specifications tubing.It is required that the frock of new spec customized is not only
It is expensive, production cost is improve, and because the required cycle customized is oversize, so as to manufacturing schedule can be influenceed.
Utility model content
The purpose of this utility model is to provide a kind of nuclear zirconium alloy pipe blasting enlarging seal assembly, is solved existing
Sealing frock clamping difference nuclear zirconium alloy pipe tested when frock cannot be general problem.
The technical scheme that the utility model is used is：A kind of nuclear zirconium alloy pipe blasting enlarging seal assembly, including
Two ends expand the nuclear zirconium alloy pipe of taper hole respectively, and two outer surfaces of taper hole are fitted and are provided with inner cone gear, and core is closed with zirconium
The inner surface laminating of one end taper hole of golden tubing is provided with hollow plug, hollow plug and passes through and the inner cone gear of its homonymy between
Through hole overcoat is connected, and the inner surface laminating of the other end taper hole of nuclear zirconium alloy pipe is provided with blind hole plug, blind hole plug
And be connected by blocking overcoat and the inner cone gear of its homonymy between.
The characteristics of the utility model, also resides in,
Through hole overcoat and lean to prevent away from one end of the nuclear zirconium alloy pipe with the hollow plug of its homonymy
The movement of hollow plug, through hole overcoat and is connected with the inner cone gear of its homonymy using thread connecting mode；Closure overcoat and same with it
The blind hole plug of side is leant away from one end of nuclear zirconium alloy pipe to prevent blind hole plug from moving, closure overcoat and same with it
The inner cone gear of side is connected using thread connecting mode.
The taper hole angle that nuclear zirconium alloy pipe two ends expand is identical or different.
The beneficial effects of the utility model are：A kind of nuclear zirconium alloy pipe blasting enlarging seal assembly of the present utility model
Frock cannot be general when clamping difference nuclear zirconium alloy pipe is tested to solve the problems, such as existing sealing frock.This reality
It is simple, easy to use with a kind of new nuclear zirconium alloy pipe blasting enlarging seal component architecture, needing the different rule of explosion
During the Pipe Test of lattice, the taper that need to be only kept off according to inner cone extends out taper i.e. accordingly to the processing of nuclear zirconium alloy pipe two ends
Can, without because purchasing spy's fixture and shelf test progress, and having broken the situation for testing consumptive material dependence external import.

Fig. 2 is a kind of structure sectional view of nuclear zirconium alloy pipe blasting enlarging seal assembly of the present utility model；
Fig. 3 is the partial enlarged drawing at A in Fig. 2.
In figure, 1. nuclear zirconium alloy pipe, 2. inner cone gear, 3. blocks overcoat, 4. hollow plug, and 5. through hole overcoat, 6. blind
Hole plug.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of structure such as Fig. 1 and Fig. 2 institutes of nuclear zirconium alloy pipe blasting enlarging seal assembly that the utility model is provided
Show, including two ends expand the nuclear zirconium alloy pipe 1 of taper hole respectively, two outer surfaces of taper hole are fitted and are provided with inner cone gear 2,
The inner surface laminating of one end taper hole of nuclear zirconium alloy pipe 1 is provided with hollow plug 4, hollow plug 4 and with its homonymy in
Be connected by through hole overcoat 5 between cone gear 2, the inner surface of the other end taper hole of nuclear zirconium alloy pipe 1 fit be provided with it is blind
Hole plug 6, blind hole plug 6 and and its homonymy inner cone gear 2 between be connected by blocking overcoat 3.
As shown in figure 3, through hole overcoat 5 and being offseted away from one end of nuclear zirconium alloy pipe 1 with the hollow plug 4 of its homonymy
By to prevent hollow plug 4 from moving, through hole overcoat 5 and it is connected using thread connecting modes with the inner cone gear 2 of its homonymy；Closure is outer
Cover 3 and lean to prevent blind hole plug 6 from moving away from one end of nuclear zirconium alloy pipe 1 with the blind hole plug 6 of its homonymy, seal
Block up overcoat 3 and be connected using thread connecting mode with the inner cone gear 2 of its homonymy.
The taper hole angle that the two ends of nuclear zirconium alloy pipe 1 expand is identical or different.If taper hole angle is identical, inner cone gear
2 can be with general；If taper hole angle is different, classification can be carried out to the inner cone at the two ends of nuclear zirconium alloy pipe 1 gear 2 and used.
A kind of nuclear zirconium alloy pipe blasting enlarging seal assembly of the present utility model is by one end of nuclear zirconium alloy pipe 1
It is connected with hollow hollow plug 4, entrance during as test；By the other end of nuclear zirconium alloy pipe 1 and solid blind hole
Plug 6 is connected, sealed end during as test.Pretightning force is kept using screw thread self-locking principle, when to through hole overcoat 5, closure
Overcoat 3 and inner cone gear 2 apply during with pretightning force more than 50N, whole modular construction stabilization, i.e., using seal with double-cone principle come real
The sealing of existing super-pressure, when internal pressure is increasing, the pressure of conical surface seal also increases therewith, maintains sealing without leakage；Profit
Prevent corresponding hollow plug 4 and the outside side shifting of blind hole plug 6 from causing respectively with the through hole overcoat 5 and closure overcoat 3 at two ends
Pressure release and leakage.
When using, two relative inner cone gears 2 can be inserted on nuclear zirconium alloy pipe 1, then in nuclear-used zirconium alloy
The two ends of tubing respectively expand 33 ° of taper hole, it is ensured that inner cone keeps off 2 conical surfaces and fitted with the enlarging conical surface outer surface of its corresponding side.Will
Hollow plug 4 is put into wherein one end taper hole, the conical surface of inboard wall laminating of the conical surface of hollow plug 4 and nuclear zirconium alloy pipe 1, and is pacified
Through hole overcoat 5 of the dress with through hole, the internal thread of through hole overcoat 5 matches with the external screw thread of inner cone gear 2 and merges with minimum 50N pretensions
Power is tightened, and the other end of nuclear zirconium alloy pipe 1 is also carried out similar assembling.With equipment connector by a kind of nuclear zirconium alloy pipe
The arrival end of explosion enlarging seal assembly couples with bursting test machine, and when starting experiment, oil medium enters core by arrival end
Inside zirconium alloy tube 1, pressure is formed in tubing by lasting oiling, inner cone keeps off 2 radial dilatations under oil pressure effect,
Self-locking action is produced under the collective effect of internal pressure and pretightning force, seal with double-cone is realized, and can keep to sample explosion.
