Abstract
Disclosed is a marine diesel engine exhaust thermometer, comprising a housing (7), wherein the housing (7) is internally provided with a mounting rack (8), a C-shaped spring tube member (9), and a compression gauge movement (10). The C-shaped spring tube member (9) is fixed upon the mounting rack (8); a temperature-sensitive pipe (1) is arranged outside the housing (7) to communicate with the C-shaped spring tube member (9) via a capillary (2); the temperature-sensitive pipe (1) is full of gas medium; the compression gauge movement (10) is assembled upon the C-shaped spring tube member (9); the compression gauge movement (10) is provided with a dial (11) and a pointer (12) driven by the C-shaped spring tube member (9); and the housing (7) is also provided with a thermometer cover (15) covering the dial (11) and the pointer (12). The marine diesel engine exhaust thermometer is heat-resisting and less affected by the ambient temperature, with little measuring error, thereby being capable of well monitoring the operation of the marine diesel engine.
Description
Technical field
The utility model relates to the thermometer of a kind of special surveying vessel with the diesel exhaust gas temperature.
Background technology
At present, in order to ensure shipping navigation safety, must guarantee the normal operation of diesel engine on the ship.Therefore, the delivery temperature to diesel engine on the ship detects apparent particularly important.During diesel engine work, body vibration is big, and the temperature of gas outlet is very high, and is very big to the thermometer influence that is installed on the gas outlet.Therefore, the thermometer that requires to be installed on the gas outlet is wanted vibration resistance, and is heat-resisting, thereby guarantees the normal use of thermometer, reaches to measure accurately durable purpose.But the C shape bourdon tube major part of traditional marine diesel exhaust gas thermometer is all made with copper material; Because the elasticity of copper material is influenced by ambient temperature very big; When temperature rises to more than 150 ℃; The elasticity of this C shape bourdon tube made from copper material can obviously descend, and causes the measuring error of this thermometer to increase, and does not have the effect of the normal operation of monitoring marine diesel.
The utility model content
The purpose of the utility model is to provide a kind of heat-resisting, influenced by ambient temperature little marine diesel exhaust gas thermometer.
In order to address the above problem; The technical scheme that the utility model adopts is: the marine diesel exhaust gas thermometer, comprise housing, and be provided with erecting frame, C shape bourdon tube parts, core of pressure meter in the housing; Described C shape bourdon tube parts are fixed on the erecting frame; Described housing is provided with the temperature-sensitive pipe through kapillary and C shape bourdon tube members outward, and gassy medium in the temperature-sensitive pipe, described core of pressure meter are installed on the C shape bourdon tube parts; Core of pressure meter is provided with index dial and can on housing, also be provided with the watch glasses that covers on outside index dial, the pointer by the pointer of C shape bourdon tube parts drive.
Described watch glasses is provided with watch glass.
Be provided with O-ring seal between described watch glass and the watch glasses.
Described temperature-sensitive pipe and extracapillary are provided with protection tube.
Described gas medium is a nitrogen.
Owing to adopt above-mentioned structure; When the temperature at the temperature-sensitive pipe of the utility model place changed, the gas medium in the temperature-sensitive pipe produced the physical phenomenon of expanding with heat and contract with cold accordingly, pressure in the temperature-sensitive pipe is increased or reduces; Produce displacement through the permanent elastomeric spring pipe of kapillary and the C shape that is connected together with the temperature-sensitive pipe; Drive the rotating shaft of core of pressure meter, the pointer that is contained in the rotating shaft is rotated, on index dial, point out measured temperature values.
The material of the permanent elastomeric spring pipe of the described C shape of the utility model has adopted good heat resistance; Receive variation of ambient temperature to influence little parelinvar; Guaranteed that the utility model thermometer can also normally use in the environment of high heat, guaranteed the measurement accuracy of marine diesel delivery temperature.Described temperature-sensitive pipe is built in the outer protection tube, has improved the shock-resistant ability of temperature-sensitive pipe, gassy medium in the described temperature-sensitive pipe.In the described housing damping oil is housed, has improved the anti-ability of shaking of thermometer.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Embodiment
Below in conjunction with accompanying drawing the concrete mode of utility model is done further description.
As shown in Figure 1, described marine diesel exhaust gas thermometer comprises temperature-sensitive pipe 1, housing 7, erecting frame 8, C shape bourdon tube parts 9, core of pressure meter 10, index dial 11, pointer 12, watch glass 13, O-ring seal 14, watch glasses 15.Be provided with erecting frame 8, C shape bourdon tube parts 9, core of pressure meter 10 in the housing 7; Described C shape bourdon tube parts 9 are fixed on the erecting frame 8; Described core of pressure meter 10 is installed on the C shape bourdon tube parts 9; Core of pressure meter 10 is provided with index dial 11 and can on housing 7, also be provided with the watch glasses 15 that covers on outside index dial 11, the pointer 12 by the pointer 12 of C shape bourdon tube parts 9 drives.Described watch glasses 15 is provided with watch glass 13.Be provided with O-ring seal 14 between described watch glass 13 and the watch glasses 15.Be provided with the temperature-sensitive pipe 1 that is communicated with C shape bourdon tube parts 9 through kapillary 2 outside the described housing 7, gassy medium in the temperature-sensitive pipe 1, described gas medium is a nitrogen.Described temperature-sensitive pipe 1 and the kapillary 2 outer protection tubes 3 that are provided with.Described kapillary 2 is communicated with temperature-sensitive pipe 1 and C shape bourdon tube parts 9; Also have a branched hair tubule between them as the inlet that charges gas medium, after having charged medium, the branched hair tubule is sealed, so just formed an airtight temp measuring system; Temperature when temperature-sensitive pipe place changes; Produce pressure in the system and change, make the permanent elastomeric spring pipe of C shape produce displacement, drive the core of pressure meter 10 that is contained on the C shape duct member 9 and rotate with pointer 12; On index dial 11, indicate corresponding temperature value, the damping oil of vibrationproof is housed in the described marine diesel exhaust gas thermometer.
In a word; The above-mentioned preferred implementation though the utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of the utility model only if such variation and remodeling have departed from the scope of the utility model.
