Specific embodiment
The sealing structure provided by the utility model based on temperature measurement component is made below with reference to embodiment further detailed, complete
Site preparation explanation.The embodiments described below is exemplary, and is only used for explaining the utility model, and should not be understood as practical to this
Novel limitation.
A kind of sealing structure based on temperature measurement component, as shown in Figure 1, include multiple temperature measurement components 1, cylinder 2, blind flange 3,
Multiple protection sleeve pipes 6 and sealing device, sealing device include multiple clamp nuts 4, multiple gaskets 5 and multiple protection sleeve pipes 6.
Temperature measurement component 1 is thermocouple, and the perforation of 2 both ends of cylinder, middle part formation through-hole, defining cylinder 2, wherein one end is opening, temperature measurement component
1 enters the through-hole from open at one end, and 2 other end of cylinder is connected to the temperature field of testing temperature to be checked.It is spaced apart and is equipped on blind flange 3
Multiple screw holes 7, as shown in Fig. 2, the screw hole 7 penetrates the both ends of blind flange 3.Screw hole 7 is trapezoidal hole, including what is communicated with each other
Macropore and aperture, the aperture of the macropore are greater than the aperture of aperture, and the inner wall of the macropore is equipped with internal screw thread, internal screw thread lowermost end
It is equipped with spacing between aperture top, i.e., is smooth macropore inner wall between internal screw thread lowermost end and aperture top.Flange
The lid of lid 3 is closed to be detachably connected in the open end of cylinder 2, blind flange 3 and cylinder 2, is equipped between blind flange 3 and cylinder 2 close
Packing, the junction for sealing flange cover 3 and cylinder 2.The screw hole 7 is connected to the through-hole in cylinder 2, specifically, screw hole 7
Aperture connection cylinder 2 through-hole.4 one end of clamp nut is equipped with external screw thread, and clamp nut 4 is equipped with externally threaded one end and protrudes into spiral shell
Hole 7 is spirally connected with the internal screw thread in screw hole 7, thus connecting flange lid 3, the other end stretches out 3 end of blind flange.Internal screw thread lowermost end and
It is set between aperture top there are two gasket 5 and a sealing ring, the direction from aperture to macropore is followed successively by gasket 5, sealing
Ring, gasket 5 and clamp nut 4, gasket 5, sealing ring, gasket 5 and clamp nut 4 successively contact compression, double-layer seal
Pad forms cross sealed, ensure that the leakproofness that clamp nut 4 is connect with blind flange 3.The quantity and arrangement of screw hole 7 can be according to surveys
The distribution of warm spot and be arranged, keep multiple thermocouples distribution across multiple screw holes 7 orderly.Clamp nut 4 is as shown in Figure 3 and Figure 4,
4 interior smooth of clamp nut contacts the thermocouple being located therein and the smooth inner wall of clamp nut 4, will not scratch pressure thermoelectricity
It is even.The side wall of clamp nut 4 offers the notch of axial direction simultaneously, and such thermocouple wire can enter by the way that the notch is interspersed
Inside clamp nut 4.Temperature measurement component 1 passes through the through-hole of clamp nut 4, the aperture of screw hole 7 and cylinder 2,1 both ends of temperature measurement component point
It Shen Chu not blind flange 3 and the through-hole across cylinder 2.The thermometric end of temperature measurement component 1 is located at the through-hole side of cylinder 2, connection display
The connecting pin of device is located at 3 one end of blind flange.The outside of temperature measurement component 1 is cased with protection sleeve pipe 6, and the outer diameter of protection sleeve pipe 6 is bigger
In the aperture of the aperture of screw hole 7, less than the internal diameter of clamp nut 4.In this way, the protection sleeve pipe 6 equipped with thermocouple can be caught in screw hole 7
Aperture, and compress the aperture, strengthen leakproofness.The protection sleeve pipe 6 uses fluorubber, prevents thermocouple wire because encountering
Wedge angle and damage, prevent from effectively preventing with the thermocouple wire outside equipment because touching causes thermocouple wire bending to become in equipment
Shape influences temperature measurement accuracy, impacts to equipment.
From the foregoing, it will be observed that described separated the thermometric end of thermocouple and connecting pin sealing based on the sealing structure of temperature measurement component,
So that temperature field locating for thermometric end is not will receive external influence, the numerical value that thermometric end is measured will not by extraneous interference,
Connecting pin will not be influenced or be damaged by the temperature at high-temperature measurement end.The sealing structure can be directly on temperature measuring equipment simultaneously
Open up or be individually made into a functional component, when being individually made into a functional component, using it is more flexible efficiently, it is more to can be used for workshop
The temperature detection of a identical equipment or distinct device, the one end of sealing structure far from connecting pin are connected to temperature field to be detected, together
When, multiple screw holes 7 open up settable multiple thermocouples on blind flange 3, and each screw hole 7 is equipped with a thermocouple, i.e., described
Sealing structure can be formed with multiple thermometric ends, while detect multiple temperature measuring points, using high efficient and flexible.Clamp nut 4 is to thermocouple
Play the role of support and positioning, multiple clamp nuts 4 make the connecting pin ordered arrangement of multiple thermocouples, do not interfere with each other, just
Each display device is connected promptly.
Be it is necessary to described herein finally: above embodiments are served only for making the technical solution of the utility model further
It explains in detail, should not be understood as the limitation to scope of protection of the utility model, those skilled in the art is practical new according to this
