VALVE FOR AUTOMATICALING BLOCKING PRESSURE LEAK OF RESET TYPE FOR INSTRUMENT MEASURING PRESSURE

摘要

The present invention relates to a reset type automatic pressure leakage blocking valve for a pressure measuring device installed between a pipe where a fluid or a gas flows, and a pressure measuring device to block a leakage of the fluid or the gas when the pressure measuring device is damaged. The present invention comprises: a main body coupled to the pipe where the fluid or the gas flows and the pressure measuring device measuring pressure of the fluid or the gas flowing in the pipe to be displayed, having a penetration hole formed from an intermediate end to an upper end, an inner flow hole formed from the intermediate end to a lower end in a diagonal direction, and a coupling hole to penetrate and cross the intermediate end; a blocking body inserted into the intermediate end of the coupling hole of the main body to open and close a gap between the flow hole and the penetration hole; a reset switch inserted into one side of the coupling hole to push the blocking body to an other side to be opened; and a cover body inserted into and coupled to the other side of the coupling hole to prevent the blocking body from being separated to the outside.
