Abstract
The utility model relates to a protective pipe of temperature sensor, which can be applicable for the temperature sensors on the hearth of circulating fluidized bed boiler, cooling-dreg device and other measuring points. The utility model is characterized in that: the device comprises a protective layer, an outer protective pipe and an inner protective pipe; the inner protective pipe is arranged inside the outer protective pipe, and the inner protective pipe is matched with the outer protective pipe tightly; the protective layer is covered on the outer protective pipe. The protective layer is a spray-welding cemented carbide powder protective layer; the material of the outer protective pipe is heat-resistant stainless steel; the material of the inner protective layer is cemented carbide. The utility model has the advantages of corrosion prevention, scouring resistance and heat resistance. The replacement for temperature sensor is convenient, and the life time is extended.
Description
Technical field
The utility model relates to a kind of temperature sensor protecting pipe, can be used for belonging to sensor technical field on the temperature sensor of measuring points such as circulating fluid bed boiler bed, slag cooler.
Background technology
Be used in the temperature sensor of measuring points such as circulating fluid bed boiler bed, slag cooler at present; protection tube surfacing alloy powder outside only; because the burning in circulating fluid bed boiler temperature is higher; be subjected to the brute force corrosion of sulfide simultaneously; the protection tube that is in operation very easily damages; cause the service life of temperature sensor short,, will cause inestimable environmental pollution in case occurrence temperature is out of control.
Summary of the invention
The purpose of this utility model is the temperature sensor protecting pipe of invention a kind of anticorrosion, antiscour, high temperature resistant, long service life.
For realizing above purpose; the technical solution of the utility model provides a kind of temperature sensor protecting pipe; it is characterized in that; it is made up of protective layer, outer protection tube, interior protection tube; interior protection tube places in the outer protection tube; be tight fit between interior protection tube and the outer protection tube, protection tube is equipped with layer protective layer outward outside.
Described protective layer is a surfacing cemented carbide powder protective layer; Described outer protection tube material is a heat-resistance stainless steel; The protection tube material is a carbide alloy in described.
The utility model adopts two-layer protective sleeve and layer protective layer.Being tight fit between temperature sensor and inside and outside protection tube connects; thereby guaranteed fitting tightly between the three; while is protection tube shell surfacing cemented carbide powder protective layer outside; these all help the heat transmission between each layer; thereby strengthen high temperature resistant, resistance to corrosion, accurately measure ignition temperature.
The utility model has the advantages that anticorrosion, antiscour, the high temperature resistant effect played.Make things convenient for temperature sensor to change, increase the service life.
Description of drawings
Fig. 1 is a temperature sensor protecting tubular construction schematic diagram;
Fig. 2 is a protection tube structural representation of loading onto temperature sensor.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, be temperature sensor protecting tubular construction schematic diagram, form by protective layer 1, outer protection tube 2, interior protection tube 3.
Selecting the outer protection tube 2 of heat-resistance stainless steel manufacturing for use, select for use carbide alloy to make interior protection tube 3, is tight fit between interior protection tube and the outer protection tube, the size of interior protection tube 3 and temperature sensor probe 4 tight fits.
Interior protection tube 3 is contained in the outer protection tube 2, outside protection tube 2 outer surfacing cemented carbide powder protective layers 1.
As shown in Figure 2, when measuring, protection tube with the mount pad thread connection of nut 5 with the furnace bottom of circulating fluid-bed, is inserted temperature sensor probe 4 in the protection tube, just the temperature of energy measurement siege.
