Abstract
The utility model discloses a high-sealing bursting pressure locking head device. The high-sealing bursting pressure locking head device comprises an upper locking module and a lower locking module, wherein an end cap and one end of a pipeline are placed between the upper locking module and the lower locking module together, and the upper and lower locking modules are locked through inner hexagonal nuts. The number of the inner hexagonal nuts is two, and the two inner hexagonal nuts are distributed at the left and right to ensure the stability in locking. According to the high-sealing bursting pressure locking head device disclosed by the utility model, the inner hexagonal nuts and the upper and lower locking modules are combined, so that the pipeline adopting the combination way and the end cap can prevent the phenomenon of missing a target under the situation of bearing the maximum pressure, the use is safe and reliable, and the stability is good.
Description
Technical field
The utility model relates to a kind of explosion bulge test device, relates in particular to a kind of high sealing burst pressure lock head device.
Background technology
Explosion is on the surface of the polymer sheet (such as film, leather etc.) at certain specification or the inside surface of tubing, container, exerts pressure continuously by liquid or air, and the maximum pressure when test sample breaks is suddenly tried to achieve the process of the burst strength of material.The purpose of test is the every mechanical property that checks pressure vessel, rationality and the reliability of structural design, and the size of actual margin of safety and other side performance.Therefore not only want in test (1) determination test container at " pressure---swell increment " relation curve of whole blasting process; (2) determination test container burst pressure.In the situation that intact data, the experimental phenomena according to measuring of container blasting fracgmentation mouth analyzed fracture apperance, make explosion bulge test result's evaluation, thereby reach the purpose of test.
The tapered end of burst pressure of the prior art relies on electrodeless clip locked, but because the portioned product required pressure is higher, in explosion bulge test, tend to occur the plug phenomenon of " missing the target ", can't finish pilot project and plug and when missing the target, have certain danger.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of high sealing burst pressure lock head device of safety and stability to be provided.
The utility model is achieved through the following technical solutions:
A kind of high sealing burst pressure lock head device, include upper and lower locking module, one end of plug and pipeline is placed between the described upper and lower locking module together, by interior hexagonal (hexagon)nut with upper and lower locking module latch, described upper and lower locking module inwall is provided with corresponding semi-circular recesses, is provided with O-ring seal between described plug and the semi-circular recesses.
Described interior hexagonal (hexagon)nut has two, is left and right distribution, guarantees the stability of locking.
The utility model has the advantages that: the utility model has adopted interior hexagonal (hexagon)nut and upper and lower two locking module combinations to form, this array mode pipeline and plug can not cause the phenomenon of missing the target in the situation that bear maximum pressure yet, safe and reliable, good stability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of high sealing burst pressure lock head device, include upper and lower locking module 1,2, one end of plug 3 and pipeline 4 is placed between the described upper and lower locking module 1,2 together, and with upper and lower locking module 1,2 lockings, upper and lower locking module inwall is provided with corresponding semi-circular recesses 6 by interior hexagonal (hexagon)nut 5, be provided with O-ring seal 7 between plug 3 and the semi-circular recesses 6, interior hexagonal (hexagon)nut has two, is left and right distribution, guarantees the stability of locking.
