Description
Technical field
The present invention is the dismountable temp sensor device of high pressure of anti-explosion electric heater.
Background technology
In order to improve the temperature of Oil, Water, Gas, conventional anti-explosion electric heater. Anti-explosion electric heater core component is explosion-proof electric heating tube. Too high in order to prevent anti-explosion electric from adding tube surface temperature, phenomenon of blasting, it is necessary to two temperature sensors, measure anti-explosion electric at any time and add tube surface temperature, by automatic control cabinet, make temperature control in certain scope. With two temperature sensors, take its meansigma methods. Temperature sensor to put in the cylinder of anti-explosion electric heater, and the front end of temperature sensor is temperature sensing district, and front end clamp is clamped on the surface of explosion-proof electric heating tube, could accurately measure the temperature on surface. During anti-explosion electric heater work, cylinder internal pressure is high, reaches 15MPa. In order to ensure sealing property good in cylinder, temperature sensor must with the tube sheet reasonable installation in flanged plate and wire connection cavity. Original technical scheme is: on the cylindrical of temperature sensor rear end, welds a sleeve pipe, sleeve pipe respectively with the Tube-sheet Welding in flanged plate and explosion-proof wiring chamber. Temperature sensor exceedes shelf-life use, can not singly only lossless change after damaging, the weld of temperature sensor rear end part cylindrical Yu sleeve pipe must be cut off, the temperature sensor damaged is extracted out from sleeve pipe, pierce into sleeve pipe with a new temperature sensor, and temperature sensor rear end part cylindrical is welded again with sleeve pipe. Replacement operation bothers, and welding quality is also more difficult to get guarantee, causes that sealing property is difficult to ensure that.
Summary of the invention
The technical problem to be solved is: provides a kind of dismountable temp sensor device of high pressure, tightens clamp nut, keeps high pressure in anti-explosion electric heater cylinder, and heating work, temp sensor device is duty. After temperature sensor damages, unscrew clamp nut, it is possible to single lossless change, do not need to cut off temperature sensor rear end part with tunica sealing of tube place, again weld with new temperature sensor.
It is such that an outside diameter being 10 millimeters for solving what above technical problem adopted technical scheme, wall thickness is 2 millimeters, material is the stainless steel tube of 316L, it is annealed heat treatment, eliminating internal stress, processing is grown up 80 millimeters, and cylindrical is through grinding, surface roughness reaches the Sealed casing pipe of 0.4 ��m, is enclosed within the part cylindrical of temperature sensor rear end. The biend of Sealed casing pipe welds with the cylindrical of temperature sensor respectively. Sealed casing pipe is cased with clamp nut, the second sealing shroud, the first sealing shroud. The outside diameter of protection sleeve pipe is 16 millimeters, and wall thickness is 2 millimeters, and length is 180 millimeters, and material is 304 rustless steels. The end face of protection sleeve pipe welds with external screw thread seal nipple, and the part cylindrical place of protection sleeve pipe welds with flanged plate, the Tube-sheet Welding in the other end of protection sleeve pipe and wire connection cavity. Temperature sensor, together with Sealed casing pipe, puts in inside external screw thread seal nipple, protection sleeve pipe. Clamp nut can screw or unscrew on thread seal joint outside, when screwing, temp sensor device is duty, when unscrewing, first sealing shroud, two sealing pipes just can unclamp from the cylindrical wall of Sealed casing pipe, that temperature sensor damaged just can be taken out from external screw thread seal nipple, the first sealing shroud, the second sealing pipe, clamp nut, changes, installs a new temperature sensor being welded with Sealed casing pipe in advance.
Owing to adopting above technical scheme, its effect is apparent from:
1, renewal cost is saved. Take out a temperature sensor damaged, it is not necessary to the weld in former technical scheme cuts off, and when installing new temperature sensor, also need not again weld, it is possible to save the renewal cost of 90%.
2, good sealing effect. The lossless replacing of temperature sensor, sealing effectiveness is with temperature sensor mounted the same first, and sealing property is guaranteed.
3, dismounting, replacing are conveniently.

Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3, the present invention is a kind of dismountable temp sensor device of high pressure, and Sealed casing pipe 12 is enclosed within the part cylindrical of temperature sensor 5 rear end, and the biend of Sealed casing pipe welds with the cylindrical of temperature sensor respectively. Sealed casing pipe is cased with clamp nut the 11, second sealing shroud the 14, first sealing shroud 13 in order. The end face of protection sleeve pipe 9 welds with external screw thread seal nipple 10, and the part cylindrical place of protection sleeve pipe welds with flanged plate 4, and the other end of protection sleeve pipe is welded with the tube sheet 3 in wire connection cavity. Temperature sensor, together with Sealed casing pipe, puts in inside external screw thread seal nipple 10, protection sleeve pipe 9. Clamp nut 11 and external screw thread seal nipple 10 cooperate, and clamp nut 11 can screw or unscrew on thread seal joint 10 outside. When screwing clamp nut, compress the second sealing shroud 14 and the first sealing shroud 13, it is achieved sealing, temp sensor device is duty.When unscrewing clamp nut 11, that temperature sensor damaged just can be taken out from external screw thread seal nipple the 10, first sealing shroud the 13, second sealing shroud 14, clamp nut 11, changes, installs a new temperature sensor being welded with Sealed casing pipe in advance.
