Description
Technical field
the present invention relates to a kind of accumulator protection valve automated detection method and device thereof, particularly relate to a kind of detection method and device thereof that valve pressure and equilibrium pressure were pressed, closed to valve of opening that is detected safety valve by computer controlled automatic.
Background technology
The safety valve element is the ten minutes critical elements in
accumulator battery production; The cracking pressure of safety valve requires in 10 ~ 49KPA scope; When the battery internal gas pressure was elevated to 10 ~ 49KPA, safety-valve was automatically opened and is carried out exhaust, when the battery internal gas pressure drops to 10KPA when following; Safety-valve is closed automatically, guarantees certain malleation in the battery.
to the detection of safety valve, in producing at present two kinds of detection methods are arranged: (one) adopts the manual inspection method; Pointer rain glass, safety valve, hand air pump are connected with threeway, and safety valve is put into water, manually inflates, and 2 atmospheric pressure values when range estimation produces bubble and stops with bubble are respectively out that valve is pressed and the method for closing the valve pressure detects.
its weak point is that trick cooperates manual work to read when requiring the workman to detect, and has personal error, is prone to cause test tired in addition, and degree of changing into is low automatically, and pick-up unit is too simple, lacks the verification standard.
(two) adopt mercury slug and electric switch detection method; Adopt the open and close valve pressure method of mercury slug and electric switch inspection safety valve; With threeway safety valve, mercury slug, source of the gas are linked together; 2 electronic switches are installed in the alarm scope up and down of mercury slug, limit Investigation on safety valve pressure and close the valve pressure, detect the mercury slug air pressure change; This kind detection can only be discerned open and close valve and whether press ultra scope, can't accomplish fine detection for the exhaust process of safety valve.
are present; Two kinds of methods of this of prior art lack the contrast means for duplicate detection repeatedly; And press to such an extent that further lack detection in the research for the safety valve equilibrium pressure for the open and close valve of safety valve; And equilibrium pressure also is to safety-valve screen resilience and the main determining factor that repeats to open and close performance, and therefore, people demand developing a kind of detection method and the device thereof that valve pressure and equilibrium pressure were pressed, closed to valve of opening that can realize comprising safety valve urgently.
Summary of the invention
the object of the invention just is to solve finer detection in the safety valve detection, and a kind of accumulator protection valve detection method and device of more science is provided for the product quality that improves safety valve.This safety valve detection side genealogy of law that the present invention provides adopts computer control software, the communication technology, detection technique knot and accumulator protection valve production technology and battery-operated principle and service experience thereof to draw mutually.
