Description
Technical field
The utility model relates to a kind of fuel tank test unit, particularly a kind of fixed sturcture of fuel tank thermocouple sensor.
Background technology
In the test specification of plastic fuel tank, some pilot project needs to measure fuel tank internal temperature, because the thermocouple sensor purchased on the market mostly adopts the fixed form of screw thread mouth, so often fix in the following ways in fuel tank test.First the mode of female weldment by hot melt is welded on plastic fuel tank, then punches on the oil tank wall of female weldment inside with power drill, as thermocouple sensor jack, then thermocouple sensor to be inserted in female weldment and to screw.
In different test specifications, there is different regulations to thermocouple sensor from the distance of fuel tank diapire.In the fixed form that thermopair is traditional, the length due to thermocouple sensor is fixing, so the end of thermocouple sensor is also fixing from the distance of fuel tank diapire, cannot carry out regulating to meet test specification requirement.Regulate the end of thermocouple sensor from the distance of fuel tank diapire, will reinstall or dismantle thermocouple sensor.When each installation or removal thermocouple sensor, because thermocouple sensor is hickey, so need the even sensor of frequent rotary thermoelectric, make the wire of thermocouple sensor easily disconnected by strand, reduce the serviceable life of thermocouple sensor.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, provides a kind of fixed sturcture of fuel tank thermocouple sensor, can regulate the insertion depth of thermocouple sensor easily.
For solving above technical matters, the fixed sturcture of a kind of fuel tank thermocouple sensor of the present utility model, comprise plastic fuel tank, described plastic fuel tank is provided with thermocouple sensor jack, the outer wall of described thermocouple sensor jack is welded with female weldment, described female weldment be hollow tubular structure and with described thermocouple sensor jack coaxial line, the bottom surface port of described female weldment is welded on described plastic fuel tank, the upper end inwall of described female weldment is provided with internal thread, the first tracheae quick connector is connected with in the internal thread of described female weldment, the upper end of described first tracheae quick connector is plugged with plastics tracheae and is tightly connected between the two, the upper end of described plastics tracheae to be plugged in the second tracheae quick connector and to be tightly connected between the two, the upper end of described second tracheae quick connector is screwed in the lower end of Double-ended nut, the upper end of described Double-ended nut is connected with thermocouple sensor, the measuring staff of described thermocouple sensor is inserted from the upper port of described Double-ended nut and is passed described second tracheae quick connector successively, plastics tracheae, first tracheae quick connector, female weldment and thermocouple sensor jack enter the inner chamber of described plastic fuel tank.
Relative to prior art, the utility model achieves following beneficial effect: the plug between tracheae quick connector and plastics tracheae is fast very convenient, as long as plastics tracheae can inject in tracheae quick connector by the Spring Card pressing tracheae quick connector port, or extract from tracheae quick connector, trip spring card can realize plastics tracheae and to be stuck in tracheae quick connector and to realize sealing; Plastics tracheae is trimmed to suitable length, just can adjusts the insertion depth of measuring staff in plastic fuel tank of thermocouple sensor; Owing to have employed tracheae quick connector and plastics tracheae, first the first tracheae quick connector and female weldment can be connected, and Double-ended nut and thermocouple sensor are connected in advance, and the second tracheae quick connector is screwed on Double-ended nut, then the measuring staff of thermocouple sensor is inserted in plastics tracheae, finally carry out the grafting of plastics tracheae, counteragent during dismounting; When so just can avoid installation or removal, thermocouple sensor is done to rotate in many weeks with its wire, thus avoids being twisted disconnected.
As improvement of the present utility model, the outer wall of described female weldment is that stepped cylindrical is step-like, and the lower diameter of described female weldment is greater than upper diameter.The floorage of so female weldment increases, and is conducive to and fuel tank firm welding.
