Description
Technical field
The utility model relates to a kind of frock that the diesel engine thermosistor is opened temperature and lift of testing, and relates in particular to a kind of frock with displacement transducer and temperature sensor.
Background technology
At present; Domestic diesel engine is to control the water temperature of engine through the inner thermosistor in water route; During engine operation because the effect of water pump; Just form the air-water mixture of certain pressure and temperature in inside, water route, for the Performance And Reliability of engine, the temperature-sensitive unit of this thermosistor just need be in the lift of certain temperature range inner control thermosistor; And then control diesel engine water route large and small round-robin flow reaches control diesel engine cooling system water temperature purpose, needs suitable thermosistor temperature rise curve mate diesel engine.The temperature rise curve of general thermosistor is the water temperature of simulated engine in tank, gets through the lift of measuring thermosistor.The temperature rise curve of measuring through such equipment can't mate the complex situations of diesel engines water cycle really, influences the water temperature control of engine, and occurs the inaccurate fault of measurement data easily.
The utility model content
The technical matters that the utility model will solve is the defective that overcomes prior art, provides a kind of simple in structure, saves the space, the test fixture that can avoid the engine water route to reveal.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
Detect the diesel engine thermosistor and open the frock of temperature and lift; Include thermosistor, said thermosistor front end is provided with the thermosistor lining vertical with thermosistor, is provided with the thermosistor lid before the said thermosistor lining; It is characterized in that: the passage one that has a perforation in said thermosistor lining, the thermosistor lid; Be inserted with a tappet in the said passage one, the right-hand member of said tappet contacts with the center section of thermosistor, and the left end of said tappet has a displacement transducer; And contact with the measurement joint of displacement transducer, said displacement transducer is installed on the displacement sensor bracket; Be set with a back-moving spring on the said tappet, said back-moving spring is between thermosistor lid and thermosistor; Said thermosistor lining lower end has the passage two that connects with thermosistor, in the said passage two temperature sensor is installed.
Described a kind of frock that the diesel engine thermosistor is opened temperature and lift that detects is characterized in that: be lined with one under the measurement joint of said displacement transducer and the tappet position contacting and regulate cushion block.
Described a kind of frock that the diesel engine thermosistor is opened temperature and lift that detects; It is characterized in that: on the said tappet successively the center of being set with plug screw, the y-type seal ring of perforate are arranged; Said plug screw is tightened in thermosistor and covers, and said y-type seal ring is between plug screw and thermosistor lid.
Described a kind of frock that the diesel engine thermosistor is opened temperature and lift that detects; It is characterized in that: be carved with screw thread on the tappet of said back-moving spring right-hand member; Nut is spun on the screw thread of tappet; Back-moving spring is fixed between nut and the thermosistor lid, and a back-up ring is arranged between said back-moving spring and the nut.
The utlity model has following beneficial effect: the utility model is simple in structure, avoids the water route to reveal, and saves the space, and is easy to process.
Description of drawings
Fig. 1 is the cut-open view of the detection diesel engine thermosistor temperature rise curve frock of the utility model.
Embodiment
As shown in Figure 1, detect the frock that the diesel engine thermosistor is opened temperature and lift, include thermosistor 11; Said thermosistor 11 front ends are provided with the thermosistor lining 13 vertical with thermosistor 11; Be provided with thermosistor lid 6 before the said thermosistor lining 13, have the passage one that connects in said thermosistor lining 13, the thermosistor lid 6, be inserted with a tappet 4 in the said passage one; The right-hand member of said tappet 4 contacts with the center section of thermosistor 11; The left end of said tappet 4 has a displacement transducer 1, and contacts with the measurement joint of displacement transducer 1, and said displacement transducer 1 is installed on the displacement sensor bracket 2; Be set with a back-moving spring 8 on the said tappet 4, said back-moving spring 8 is between thermosistor lid 6 and thermosistor 11; Said thermosistor lining 13 lower ends have the passage two that connects with thermosistor 11, in the said passage two temperature sensor 12 are installed.
Be lined with one under the measurement joint of said displacement transducer 1 and tappet 4 position contacting and regulate cushion block 3.
On the said tappet 4 successively the center of being set with have plug screw 5, the y-type seal ring 7 of perforate, said plug screw 5 to be tightened on the thermosistor lid 6, said y-type seal ring 7 covers between 6 at plug screw 5 and thermosistor.
Be carved with screw thread on the tappet 4 of said back-moving spring 8 right-hand members, nut 10 is spun on the screw thread of tappet 4, and back-moving spring 8 is fixed between nut 10 and the thermosistor lid 6, and a back-up ring 9 is arranged between said back-moving spring 8 and the nut 10.
