Abstract
The utility model belongs to the technical field of low speed diesel engine exhaust gas temperature measuring devices, particularly relates to a shock-absorbing temperature sensor, and aims to solve the technical problem of providing a temperature sensor with high sensitivity, stable work, shock absorption and durability. To solve the technical problem, the temperature sensor provided by the utility model adopts the structure as follows: the temperature sensor comprises a sensor protecting sleeve, a sensor mounted in the inner chamber of the sensor protecting sleeve, a locking device for fixing the sensor protecting sleeve and the sensor, and a shock-absorbing device, wherein the shock-absorbing device is arranged in the inner chamber of the sensor protecting sleeve at the front end of the sensor. The utility model has the effects as follows: 1, the measurement reliability of the temperature sensor is improved, normal operation of the diesel engine is ensured, and the work efficiency is improved; and 2, by virtue of the shock-absorbing device, the anti-seismic performance of the utility model is greatly enhanced, and meanwhile the sensitivity of the temperature sensor is improved. Moreover, the utility model has compact structure, reasonable design, simple processing, and convenient operation and installation.
Description
Technical field
The utility model belongs to low-speed diesel engine delivery temperature measurement mechanism technical field, relates to a kind of damping temperature sensor specifically.
Background technology
Temperature is a basic physical amount, and all processes of occurring in nature are closely related with temperature invariably.Temperature sensor is to develop the earliest, a most widely used class sensor.The market share of temperature sensor has substantially exceeded other sensor.First people begin to utilize temperature to measure from 17th century.Development along with industrial technology, people begin sensor is used in the middle of the commercial unit, in the prior art, temperature sensor in the low-speed diesel engine exists the shortcoming of following two aspects, on the one hand owing to the sensor top does not contact with the interior top of chamber of sensor protection cover, because the vibration that diesel engine produces in operation process can cause the generation of situations such as temperature sensor ruptures easily; On the other hand, because the sensor protection cover of temperature sensor and sensor is not directly to contact, makes temperature sensor sensitivity not high, thereby influence the functional reliability of temperature sensor.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of highly sensitive, working stability, the temperature sensor that damping is durable.
For solving the problems of the technologies described above; temperature sensor of the present invention adopts a kind of like this structure: it comprises the sensor protection cover; be installed in sensor and the locking device that is used for fixing sensor protection cover and sensor in the sensor protection cover inner chamber; also comprise a shock attenuation device; described shock attenuation device is arranged in the sensor protection cover inner chamber of sensor front end, is connected with sensor.
As a further improvement on the present invention, described shock attenuation device is a high temperature resistant stage clip;
As a further improvement on the present invention, described locking device is a nut, and described nut overlaps rearward end for being threaded with sensor protection.
Temperature sensor of the present utility model has improved the reliability of temperature sensor work measurement on the one hand, guarantees the diesel engine operate as normal, promotes its work efficiency; Because the setting of shock attenuation device has strengthened its anti-seismic performance greatly, also improved temperature sensor sensitivity simultaneously on the other hand, and the utility model compact conformation, reasonable in design, processing is simple, and operation and installation are convenient.
Description of drawings
Fig. 1 is a main structure chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation in further detail.
Fig. 1 shows the main structure chart of the preferred implementation of temperature sensor of the present utility model.It comprises sensor protection cover 1, sensor 2, high temperature resistant stage clip 3 and nut 4; Sensor 2 and high temperature resistant stage clip 3 are arranged on sensor protection and overlap in 1 inner chamber, and the nut 4 that is arranged on sensor 2 and sensor protection cover rearward end, and nut 4 and sensor protection overlap between 1 the rearward end for being threaded.
In the process that the utility model is using, because sensor 2 compresses high temperature resistant stage clip 3, vibration when the caused gas outlet of exhaust airstream, buffer action through high temperature resistant stage clip 3 has obtained later on weakening greatly, thereby weakened the influence of external shock to sensor 2, and because high temperature resistant stage clip 3 overlaps 1 inner chamber with sensor 2 and sensor protection and contacts closely, changed with front sensor 2 and in sensor protection cover 1, be in unsettled state, cause the generation of accidents such as fractureing easily because of the influence of external shock, thereby further improved the serviceable life of temperature sensor, anti seismic efficiency is good; On the other hand before the high temperature resistant stage clip 3 of adding, sensor 2 is not directly to contact with sensor protection cover 1 interior top of chamber, outside heat passes to sensor 2 through sensor protection cover 1 needs certain sensitive time, sensor 2 just can react the true temperature in the Diesel Engine Exhaust Pipe, and sensitivity is not high; And high temperature resistant spring 3 two ends of temperature sensor of the present utility model respectively and sensor 2 tops and sensor protection overlap between the front end of 1 inner chamber and be in direct state of contact; heat passes to high temperature resistant stage clip through the sensor protection cover and passes to sensor later on rapidly, thereby can improve the reaction sensitivity of temperature sensor greatly.
As shown in Figure 1; because high temperature resistant stage clip 3 is compressed in the front end of sensor 2; high temperature resistant stage clip 3 can produce a screen resilience to sensor; make sensor 2 move backward; thereby make and become lax between sensor and the high temperature resistant stage clip 3; can weaken the effect of high temperature resistant stage clip 3 after long-time; for avoiding the generation of this kind situation; we are provided with a nut 4 in the rear end of the sensor protection cover 1 of sensor 2; nut 4 overlaps 1 rear end with sensor protection and is threaded; can stop sensor to move so backward, play the effect of lock sensor 2 and high temperature resistant stage clip 3, further consolidate temperature sensor anti seismic efficiency of the present utility model and sensitivity.
