2results about How to "Avoid finding" patented technology

The utility model discloses a marine methanol engine fuel leakage monitoring devices, including connecting channel block, two -way electromagnetic valve and methanol concentration sensor, and the methanol double -walled common rail pipe is fixed between the connection of a plurality of connecting channel blocks respectively. Two -way electromagnetic valve body embeds and fixes in the big end sink hole of connecting channel block rear side ladder sink hole, and the valve core of two -way electromagnetic valve embeds the small end sink hole in the ladder sink hole, and the small end sink hole is perpendicular with the intercommunication hole vertical intersection. The outside of connecting channel block front end center observation window sink hole is equipped with installed transparent observation window, and the one end of detection channel hole is communicated with observation window sink hole respectively, and the other end is perpendicular with the corresponding several outer tube lead -through hole vertical intersection respectively. Methanol concentration sensor lower end is fixed in the upper end of sensor screw hole. The utility model discloses can find the leakage point of methanol double -walled common rail pipe in time fast accurately, and the user is convenient for timely maintenance, thereby has improved the security in the use process of marine methanol engine significantly.
