Embodiment
The high-temperature machinery formula attemperating unit of the hot stove of a kind of suitable spoke, it is located in the space between heating wire and the boiler face.Shown in Fig. 4-6, it is provided with a temperature probing tube 7 for body 101, be arranged with heatproof rod 8 in the temperature probing tube 7, described heatproof rod 8 is a ceramic rod, heatproof rod 8 belows are provided with ceramic thimble 1, are provided with shell fragment 9 in thimble screens place 11 of thimble 1, and described shell fragment 9 is provided with salient point 91, be provided with another shell fragment 2 in the below of described shell fragment 9, and also be provided with salient point 21 on this shell fragment 2.Pottery thimble 1 below is provided with adjusting nut 12, and nut 12 is provided with spring 6, and spring 6 is provided with a metal cap 5 and is connected with it.Wherein the body below is provided with an interface 102 that is connected with the hot stove of spoke.
Cooperate shown in Figure 7ly, the utility model heats up temperature probing tube 7 expanded by heating lengthening when the energising of the hot stove of spoke, heatproof rod 8 is (because heatproof rod 8 is a ceramic rod, thermal coefficient of expansion is little, so its thermal expansion can be ignored) be crushed on ceramic thimble 1 on the spring 6 toward 7 li tops of temperature probing tube, when spring 6 makes thimble 1 screens leave the prominent point 91 of shell fragment 9, shell fragment 9 actions, close in contact 10, contact 11 at this moment, 2 connections of A, B, and indicator light 13 is bright, at this moment the temperature of representing boiler face surpasses 80 degree, prevents to scald.Temperature continue to rise, and the thermal expansion of temperature probing tube 7 strengthens, when spring 6 makes the metal cap 5 that is connected on the spring 6 push up prominent point 21 on the shell fragment 2, shell fragment 2 actions, close in contact 3, contact 4, and at this moment C, D point disconnects, all-radiant furnace outage stopping heating, as shown in Figure 8, on the contrary then energising.The variation of the utility model control temperature spot can be set by adjusting nut 12.
The length of above-mentioned heatproof rod 8 slightly is shorter than the diameter of radiated heat stove plate, so with regard to the temperature of each point in the stove all very fast response become the thermal deformation of heatproof rod 8, and can react the state of local overheating.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique under the situation that does not break away from spirit and scope of the present utility model, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
