Its technical scheme does for, airtight automatic sampler for tank car loading includes that one end inserts the inside straight tube of quick-operation joint male end, the other end of straight tube is connected with diaphragm metering pump entry end through the outlet valve, diaphragm metering pump is connected with the controller, and the tank deck of tank car is provided with the radar level gauge that is used for the interior liquid level of jar, the radar level gauge is connected the controller, the exit end of diaphragm metering pump is connected with out appearance pipe. The utility model discloses during the use, when canning the tank car, arrange the appearance mouth department of appearance pipe in with the sample container, open the outlet valve, the controller is given back to the liquid level condition in the radar level gauge real-time detection canning jar, and the controller receives the rotation of feedback information control diaphragm measuring pump, through diaphragm measuring pump extraction liquid through the appearance pipe get into the sample container in, rotate the purpose that realizes the ration sample through control diaphragm measuring pump. When the liquid level detected by the radar liquid level meter reaches a set height, the controller controls the diaphragm metering pump to stop rotating, the outlet valve is closed, and the sampling container is taken away for carrying out related sampling tests.
The straight pipe is inserted into the pipe orifice at one end of the male end of the quick connector and is obliquely arranged. The pipe orifice is obliquely arranged to play a role in guiding the flow direction of liquid, and the liquid medium can enter the diaphragm metering pump through the outlet valve without external power when entering the tank.
The port of the quick-operation joint male end is provided with a flange plate, and the quick-operation joint male end is welded with the straight pipe through the flange plate.
The flange plate is a square flange plate.
The sampling pipe comprises a right-angle elbow and a metal hose, one end of the right-angle elbow is connected with the outlet end of the diaphragm metering pump, and the other end of the right-angle elbow is connected with the metal hose.
The embodiment of the utility model provides a beneficial effect that technical scheme brought is: through setting up the sampler on tank car lower charge mouthful dry-type quick-operation joint male end, and through the size of diaphragm flow pump control sample flow, realize carrying out the automatic sampling of sealed canning in-process to the tank car, guarantee loading sample efficiency, save time. Avoid through the manhole sample of setting on the roof, the sample is convenient, and can not produce the condition that the sample medium splashes, has guaranteed staff's personal safety. The sampling pipe is complementary with the original unloading pipeline all the time, so that the sampling tightness is ensured, the airtight sampling in the loading process of the tank car is realized, the sampling medium cannot be doped with other impurities, and the accuracy of a sampling detection result is ensured.
