Description
Technical field：
The utility model is related to a kind of digestion instrument, more particularly to a kind of pressure dispelling tank.
Background technology：
Pressure dispelling tank meets sample composition analysis needs mainly for the treatment of sample, in Chinese patent literature, discloses
A kind of novel pressure counteracting tank（CN206192755U）, it is that contact connects due to squeezing between lid, cup lid, cup body and tank body
It connects, connection is too closely, tight with tank body particularly because of squeezing lid in pressure when excessive although good airproof performance
Contiguity is touched, in addition squeezing the ductility that lid compression has, is prevented pressure from leaking in time, can be led to the generation of quick-fried tank event.
Utility model content：
Technical problem to be solved in the utility model is：Overcome the deficiencies of the prior art and provide it is a kind of it is simple in structure, can
To disassemble, prevent that the pressure dispelling tank of quick-fried tank occurs in the case where pressure is excessive.
The technical solution of the utility model is：A kind of pressure dispelling tank, including outer tank and inner canister, inner canister is placed in outer tank,
Outer tank includes tank body and head cover, and inner canister includes inner tank body and cover, and interior set is used between the bottom wall of tank body and the bottom wall of inner tank body
The collet of inner tank body is supported, is provided with annular groove on the cover, and is arranged in the inner tank body and matched use,
The head cover is screwed onto by screw thread on tank body, and screw hole is provided on the head cover, and mandril is provided in the screw hole, described
The pressure release module with truncated cone-shaped through-hole is provided between head cover and cover, the truncated cone-shaped through-hole is used cooperatively with mandril, institute
State the relief hole being provided on head cover for pressure release.
The screw thread being used cooperatively with the screw hole is provided on the mandril, is provided on the mandril and tightens through-hole.Institute
The diameter for stating cover and pressure release module is identical with the diameter of inner tank body, and the material of the cover, pressure release module and inner tank body
It is polytetrafluoroethylene (PTFE), the tank body is stainless steel.
The beneficial effects of the utility model are：
1st, the utility model is realized by the improvement on the basis of existing between cover, pressure release module, mandril and tank body
It is used cooperatively, realizes when pressure is excessive, the rapid dump of pressure.
2nd, annular groove is provided on the utility model cover, realizes that the tight fit of cover and inner tank body uses, prevents
Because poorly sealed, caused by unexpected pressure release.
3rd, the utility model is provided with mandril, by rotating mandril, realizes the pressure for adjusting pressure release module and cover, realizes
Cover is to the leakproofness of inner tank body.
4th, truncated cone-shaped through-hole is provided in the utility model pressure release module, and is used cooperatively with mandril, and cover and pressure release
There is gap between module and tank body, when the compression of pressure release module is extended, convenient for releasing for pressure.
Description of the drawings：
Fig. 1 is the structure diagram of pressure dispelling tank.
Fig. 2 is the decomposition texture schematic diagram of pressure dispelling tank.
Fig. 3 is the vertical view of pressure release module.
Specific embodiment：
Embodiment：Referring to Fig. 1, Fig. 2 and Fig. 3, in figure, 1- tightens through-hole, 2- screw threads, 3- head covers, 4- relief holes, 5- pressure releases
Module, 6- covers, 7- inner tank bodys, 8- mandrils, 9- tank bodies, 10- collets, 11- annular grooves, 12- screw holes, 13- truncated cone-shaped through-holes.
Pressure dispelling tank, including outer tank and inner canister, inner canister is placed in outer tank, and outer tank includes tank body 9 and head cover 3, inner canister packet
Inner tank body 7 and cover 6 are included, it is interior between the bottom wall of tank body 9 and the bottom wall of inner tank body 7 to set the collet 10 for being used to support inner tank body 7, tank
Annular groove 11 is provided on lid 6, and is arranged in inner tank body 7 and matched use, head cover 3 are screwed onto tank body by screw thread
On 9, and screw hole 12 is provided on head cover 3, mandril 8 is provided in screw hole 12, is provided between head cover 3 and cover 6 with round platform
The pressure release module 5 of shape through-hole 13, truncated cone-shaped through-hole 13 are used cooperatively with mandril 8, and the relief hole for pressure release is provided on head cover 3
4。
The screw thread being used cooperatively with screw hole 12 is provided on mandril 8, is provided on mandril 8 and tightens through-hole 1, cover 6 and is let out
The diameter of die block 5 is identical with the diameter of inner tank body 7, and the material of cover 6, pressure release module 5 and inner tank body 7 is polytetrafluoro
Ethylene, tank body 9 are stainless steel.
In use, realizing turning for mandril 8 by tightening through-hole 1, make to contact between pressure release module 5 and head cover 3；Mandril 8
It squeezes pressure release module 5 to be adjacent to cover 6, at this point, 7 inside of inner tank body is sealing state, when pressure is excessive, pressure is by cover 6
Pressure release module 5 being transferred to, then under certain pressure, pressure release module 5 is squeezed, and is extended, and is unfolded toward both ends, meanwhile, it drives
The up displacement of pressure release module 5；At this point, excess pressure gas enters the gap between cover 6 and pressure release module 5 and tank body 9, and by
Relief hole 4 is discharged.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, it is every according to the technical essence of the utility model to above example made it is any it is simple modification, equivalent variations with
Modification, in the range of still falling within technical solutions of the utility model.
