The possibility closed is larger, therefore, according to different liquid or gas medium, is controlled unidirectionally by the Flow-rate adjustment screw rod 5 of setting
Gap between valve element 4 and tapered hollow pipe 3.
With reference to figure 2, after opening pressure switch B, the work of pressure difference and uninterrupted in tapered hollow pipe 3 of nonreturn valve core 4
The delivery port of tapered hollow pipe 3 is moved upward under, after the import and export pressure differential balance of tapered hollow pipe 3, nonreturn valve core
4 from top to down slowly fall.When producing certain pressure difference or flow when leakage or quick-fried table occur for pressure gauge A, nonreturn valve core 4
After being contacted with the exit of tapered hollow pipe 3 and realization is closed automatically.When the company of this pressure gauge explosion-proof leakage-proof quick breaker and pressure gauge A
When jointed tubular workpieces are longer, nonreturn valve core 4 easily forms one direction shut-off, and pressure gauge A can not normally be shown, now opens bypass pipe 8
Valve module of voltage regulation 15 to eliminate the pressure difference of the import and export of nonreturn valve core 4, and wait pressure gauge A show it is normal after, closing pressure-regulating valve
Component 15.In addition, when installing pressure gauge A first or changing pressure gauge A with pressure, valve module of voltage regulation 15 also can be used to eliminate
The import and export pressure difference of nonreturn valve core 4, the state for returning to out nonreturn valve core 4.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right
Property scope.
