Description
Technical field
The utility model relates to pressure checking device technical field, is specifically related to a kind of grip device of tank burst pressure detector.
Background technology
Current is all tank body to be tested is enclosed within test axle core for detecting the method for tank body tube wall strength usually, makes sealing in tank body, is then inflated in tank body, to reach testing goal by the air intake opening tested on axle core.But existing tank burst pressure pick-up unit, generally that sealing effectiveness is undesirable, after insufflation gas with only using plug sealable tank mouth, easily leak gas when tank body withstand voltage (convex tank intensity) is detected with burst strength, tank mouth and the situation such as plug is separated, affect test result accuracy.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is the grip device providing a kind of tank burst pressure detector, and good sealing effect, test result is comparatively accurate.
For achieving the above object, the utility model adopts following technical scheme:
A kind of grip device of tank burst pressure detector, comprise and to be detected monolateral there is the tank body of opening and the test axle core for installing tank body, one end cross-under of test axle core, in tank body, test axle core is provided with the seal with the inwall close fit of tank body opening part; The inwall of tank body coordinates formation one seal cavity with the outside surface of the test axle core stretched in tank body; The grip device of this tank burst pressure detector also comprises one and is held on tank body opening part and is fixed on chuck on test axle core to make tank body.
Preferably, seal is the O-ring seal being sheathed on test axle core outer surface.
Preferably, the grip device of tank burst pressure detector also comprises being arranged on tests axle core outer surface and the test collar be positioned at outside seal, and this test collar is provided with teeth groove, and the opening part of tank body is provided with the flange be embedded in teeth groove.。
Preferably, grips is in flange place.
Preferably, the collar is bolted to test axle core outside surface by one is tested.
Preferably, chuck is cross section is half-moon-shaped fixture.
The beneficial effects of the utility model are:
Compared to prior art, the grip device of tank burst pressure detector of the present utility model, be arranged on the inwall close fit of seal on test axle core and tank body opening part, make sealing in tank body, the chuck be simultaneously provided with can make tank body can better be fixed on test axle core when inflating, when preventing test tank body and hermetic unit from, make pinch seal better, test result is more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the teeth groove on the test collar of the present utility model.
Wherein, 10, tank body; 20, axle core is tested; 21, O-ring seal; 22, the collar is tested; 221, teeth groove; 30, chuck.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
The grip device of a kind of tank burst pressure detector as shown in Figure 1 and Figure 2, to be tested and monolateral there is opening tank body 10 and test axle core 20, in the present embodiment, this test axle core 20 is arranged on pressure detecting instrument, specifically when testing, the above-mentioned tank body 10 with opening is arranged on the outside surface of test axle core 20, the one end testing axle core 20 is made to enter tank body 10 from the opening part cross-under of tank body 10 inner, a seal is set on test axle core 20 simultaneously, when tank body 10 is arranged on test axle core 20, the opening part inwall close fit of the seal and tank body 10, so, the inwall of tank body 10 will coordinate formation one seal cavity with the outside surface of the test axle core 20 stretched in tank body, the compressive resistance and its air-tightness that detect tank body 10 is inflated by test axle core 20 pairs of sealing spaces.
In addition, to when inflating in tank body 10, often make because tank body 10 internal gas pressure is excessive tank body 10 depart from test axle core 20, therefore be provided with the chuck 30 that is clamped in tank body 10 opening part in the present embodiment, make tank body 10 can firmly be arranged on test axle core 20, and chuck is only held on tank body opening part, be applied to can body test part without outer acting force, can body suspended, when preventing test tank body 10 and hermetic unit from, make pinch seal better, test result is more accurate.Certainly, the cross section of above-mentioned chuck 30 specifically can in half-moon-shaped, and clamping effect is better, and above-mentioned chuck 30 promotes by pneumatic element, convenient manipulation.
Preferably, above-mentioned seal is specifically as follows O-ring seal 21, and O-ring seal 21 is set in test axle core 20 outside surface, sealing effectiveness is better; Certainly, the seal adopts the blob of viscose being directly fixed on test axle core outer surface also can reach above-mentioned sealing effectiveness.
Preferably, the grip device of the tank burst pressure detector in the present embodiment also can comprise the test collar 22, this test collar 22 is fixed on test axle core 20, and make this test collar 22 be positioned at the outside of seal, teeth groove 221 is set on this test collar 22 simultaneously, accordingly the flange be embedded in teeth groove 221 is set at the opening part of tank body 10, this flange is made to be embedded in teeth groove 221 when testing, to strengthen the friction force between test axle core 20 collar and the inwall of tank body 10 opening part, clamping effect is better.Further, above-mentioned chuck 30 can be made to be clamped in above-mentioned flange place, and fastening effect is better.Further, the above-mentioned test collar 22 is specifically bolted to the outside surface of test axle core 20 by one, easy disassembly.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
