The replacement of measuring device, nothing needs to change entire tile fragment, and then saves resource and cost.
The temperature measuring equipment mounting structure for the support tile fragment that the utility model embodiment provides, you can be suitable for large-scale branch
Tile fragment is supportted, small-sized support tile fragment can also be used in.However, for large size supports tile fragment, since its thickness is larger, because
This, mounting means is more flexible.For example, the mounting means of the temperature measuring equipment for existing support tile fragment, is usually being propped up
Suitable mounting hole is processed on support tile fragment, then temperature probe such as flush type thermal resistance is embedded in mounting hole, then use screw thread
Temperature probe is fixed in mounting hole by the mode of compression.This mounting means of temperature probe usually requires on support tile fragment
The larger mounting hole of processing dimension is not suitable for the installation of temperature probe in small-sized support tile fragment.And support provided by the present application
Tile fragment is particularly suitable for the installation of temperature measuring equipment in small-sized support tile fragment.The thickness that the small-sized support tile fragment refers to is substantially in 20mm
The support tile fragment of~30mm.The size of machinable mounting hole is relatively small on this support tile fragment, cannot be compressed by screw thread
Mode fix temperature probe.Mounting hole is processed into threaded hole by the present embodiment, is used for connection screw thread formula temperature measuring equipment,
Reliable installation of the temperature measuring equipment in mounting hole can be met and conveniently realize the dismounting behaviour of temperature measuring equipment
Make.
Support the shape of tile fragment usually arc-shaped in steam turbine, and the thinner thickness of small-sized support tile fragment, generally in order to
Can on small-sized support tile fragment processing dimension bigger threaded hole, it is preferred real one in order to the installation of temperature measuring equipment
It applies in example, the axial direction of the threaded hole and the radial direction of the support tile fragment have angle, which, such as can be at least more than 0 °
It is 5 °~75 °.
Based on the steam turbine support tile fragment that the utility model embodiment first aspect provides, the utility model embodiment the
Two aspects provide a kind of support watt component, and the support watt component includes the screw-type temperature measuring equipment being threadedly coupled and support
Tile fragment, the support tile fragment are that the steam turbine according to the utility model embodiment first aspect supports tile fragment.Specifically,
It is machined with external screw thread on the peripheral surface of the screw-type temperature measuring equipment, is machined on the support tile fragment described for installing
The mounting hole of screw-type temperature measuring equipment is machined with the outer spiral shell with screw-type temperature measuring equipment on the inner peripheral surface of the mounting hole
The internal thread that line matches；When screw-type temperature measuring equipment to be mounted on support tile fragment, pass through the interior spiral shell in mounting hole
Line is directly threadedly coupled to realize fixation between the two with the external screw thread of screw-type temperature measuring equipment.It should be noted that
The axial length of internal thread in the threaded hole can only account for a part for the axial length of entire threaded hole, can also be equal to
The axial length of entire threaded hole.For example, it is assumed that the overall depth of threaded hole processed on support tile fragment is 22mm, then screw thread
The axial length of internal thread in hole can be 8mm~10mm, can also be 22mm.
The type of the screw-type temperature measuring equipment can there are many.In a preferred embodiment, the screw-type temperature
It can be that screw thread resistance temperature is popped one's head in spend measuring device.
Refering to fig. 1, specifically, screw thread resistance temperature probe includes the armoured thermal resistance 1 being sequentially connected electrically, first draws
Outlet 3, oil catch 4 and the second lead-out wire 5；The periphery close to one end end of first lead-out wire 3 of the armoured thermal resistance 1
External screw thread 2 is machined on face.
More specifically, the specification of external screw thread 2 for example can be M5 screw threads.The axial length of armoured thermal resistance 1 for example can be with
It is 21mm~23mm, preferably 22mm；The cross section of armoured thermal resistance 1 is generally circular in cross section, and the diameter of the circular cross section is for example
Can be 3.5mm~4.5mm, preferably 4mm.The axial length of external screw thread 2 for example can be 7mm~9mm, preferably 8mm；Armour
The cross-sectional diameter with 2 part of external screw thread for filling thermal resistance 1 for example can be 5mm.The length of first lead-out wire 3 for example can be with
For 500mm, cross-sectional diameter for example can be 2mm.The length of oil catch 4 for example can be 15mm, and cross-sectional diameter for example can be with
It is 2.2mm.The length of second lead-out wire 5 for example can be 2500mm, and cross-sectional diameter for example can be 2mm.
In order to have the screw thread resistance temperature of above-mentioned specification probe to be mounted in support tile fragment, add on the support tile fragment
Work has threaded hole.Specifically, with bore mode along the outer surface trepanning of support tile fragment, the radial direction of bore axis and support tile fragment
At an acute angle, trepanning depth substantially 22mm~24mm processes the internal thread of M5 in trepanning, screw thread axial length be 8mm~
12mm；Then it will pop one's head in and be tightened in mounting hole from threaded screw thread resistance temperature, until the armouring of screw thread resistance temperature probe
The end face of one end and the bottom surface of threaded hole of separate first lead-out wire 3 of thermal resistance 1 abut against.
In a preferred embodiment, in order to easily the screw-type resistance temperature is popped one's head in from the support tile fragment
Middle taking-up, the armoured thermal resistance 1 process fluted, the groove energy on the end face of one end of first lead-out wire 3
Enough accommodate dismantling device such as screwdriver.When needing to remove screw-type resistance temperature probe, with screwdriver by above-mentioned groove
Screw-type resistance temperature can be popped one's head in and be taken out.
Compared with cured type temp probe, the dismounting popped one's head in from threaded screw-type resistance temperature is simpler, conveniently,
Conducive to the replacement of temp probe, avoid because support tile fragment temperature measuring point damage due to be forced replace support tile fragment caused by
This waste has preferable promotional value.

Specifically, winding two units of power plant of China of state configure 4 small turbines altogether, and every small turbine is equipped with 2 sets of supports
Bearing often covers 2 pieces of spring bearing lower part support tile fragment and installs temperature probe, installs 8 sets of temperature probes altogether, temperature probe is using solid
Change the mode of installation.Temp probe failure or lead-out wire failure can cause thermometric to fail, to solve this problem, it is necessary to general watt
Block returns to manufacturer and carries out handling or directly replacing tile fragment.Not only delay maintenance duration, but also increase the cost of overhaul.
Using from after threaded screw-type resistance temperature probe, only bore mode need to be used to be taken temperature point is damaged
Go out, processes the internal thread of M5 in former installation bore ends, can realize the reliable installation of probe.If being changed to outlet after this probe to visit
Head failure then can easily replace probe, without returning factory's maintenance or integral replacing tile fragment, shorten maintenance duration, reduce
Maintenance cost.
Based on the support watt component that the utility model embodiment second aspect provides, the utility model embodiment third aspect
