Description
Technical field
The present invention relates to a kind of lid burst pressure detection devices, belong to pressure-detecting device technical field.
Background technique
So-called explosion is big energy in limited bulk and the phenomenon that discharged rapidly in the short time with hurried conversion.It is
A kind of extremely rapid physically or chemically energy release process, in the process, the potential of system is changed into the mechanical energy of movement,
Then externally acting.Thus blasting phenomena shows two stages, and in first stage, the energy of substance is in some way
It is changed into strong compression energy；In second stage, compression energy sharp expands outward, externally does work in expansion process,
Cause the deformation, movement and destruction that are applied object medium.
Burst pressure detection device is exactly to be filled with compressed air into cavity in a short time, and compressed air is made to generate compression
Can, when compression energy reaches the limiting value of lid receiving, compression energy sharp expands outward, and explosion (destruction) occurs for lid, this
When pressure value be lid burst pressure.
Certain type product in the prior art, product main body are class column structure, and middle part is cavity, are pacified in product main body front end
Then sealing ring and front cover body before filling tighten sealing, sealing ring and rear cover body after the installation of rear end, after then passing through by drive end bearing bracket
End cap is tightened sealing, front cover body and rear cover body and is made of Noryl (plastics) material, stores and transports in the product
Front cover body and rear cover body seal in the process, more convenient in order to operate with, and enhance rapid response capacity, it is desirable that described
The front cover body and rear cover body are not opened when product use, the pressure explosion for making it that the interiors of products be leaned on to generate, and according to institute
State product needs, the burst pressure of front cover body and rear cover body needs to meet following index: the pressure rising time of pressurising explosion cannot surpass
3 seconds are spent, burst pressure force value is in 0.15MPa~0.26MPa.Therefore the burst pressure to front cover body and rear cover body is needed to examine
It surveys.
The burst pressure detection method of front cover body to the product and rear cover body in the prior art are as follows: by the product
After front cover body and rear cover body assemble, it is filled with compressed air in Xiang Suoshu product cavity, when pressure reaches front cover body and rear cover body
Power limit when, front cover body and rear cover body explosion detect burst pressure.There is uncertainty in the method, not can determine that front cover
Which the first explosion of body and rear cover body, while a product cannot repeat to bear multiple burst pressure, every batch of checks and accepts front cover body
With the product can be all consumed when rear cover body, cause damages.
