Abstract
The utility model relates to a temperature measuring instrument, in particular to a thermal electro-coupling for high temperature furnace. The utility model is characterized in that aluminum and magnesium powder beads are arranged in a first bolt, and a movable cutting ferrule banded at the external diameter of a reinforcing pipe is arranged in a second bolt. The base is provided with a boss with a convex shoulder, and the boss is provided with a plug lid with a looking glass hole. The diameter of the shoulder dish of the plug lid is larger than the external diameter of the boss, and the lower opening on the outer edge of the base is a circular arc. A fabric bag is arranged outside the corundum pipe, and the bottom end of the reinforcing pipe extends into the base. The magnesium powder is crushed in a hole in the clamping mode in the first bolt, and with the nut tightened further, the aluminum and magnesium powder is clamped with the thermocouple wire to prevent the flame in the pipe being blown out and avoid the terminal box to be burnt out. The movable cutting ferrule acts on the external diameter of a bushing, and is tightened by the nut to make the cutting ferrule be banded at the external diameter of the reinforcing pipe, to achieve to prevent the rain water flowing into the furnace from the joint. Adopting the fabric bag sheathed outside the corundum pipe of the thermal electro-coupling ensures that the thermal electro-coupling bushing can not fall down into the furnace chamber when ruptured and the service life of the thermal electro-coupling can be prolonged.
Description
Technical field
The utility model relates to a kind of temperature instrumentation, relates in particular to a kind of to the thermopair by the improved a kind of High-temp. kiln of thermopair of thermometric in the pressure burner hearth.
Background technology
The thermopair of the burner hearth thermometric of the applicant's application; be characterized in: flange is equipped with stainless steel garden iron in the middle of the bottom; stainless steel garden iron is built-in with two holes suitable with thermopair; the thermopair outside is equipped with inwall and presents the little pressure reducing sleeve of big taper down; be equipped with the inorganic solidification agent that is used to seal between pressure reducing sleeve and the thermopair, terminal box and protection tube cooperatively interact and are fixed on the flange by the loose joint nut.Having solved in the use thermopair can be high pressure resistant, corrosion-resistant, anti-embrittlement, but its weak point, reinforcement pipe adapter connection place, meet water and flow into the thermopair heat expansion shrinkage that makes high temperature in the stove and produce explosion and scrap, or furnace flame burns out terminal box when inner core is emerged and causes the loose contact of terminal box internal wiring terminal.
Summary of the invention
In order to overcome the deficiency that prior art exists, the utility model provides a kind of thermopair that outer water flows in the stove, gas stream in the stove flows out the outer a kind of High-temp. kiln of terminal box that prevents to manage.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of thermopair of High-temp. kiln, it comprise be arranged on the terminal box bottom the reinforcement pipe by bolt tightening in base, this reinforcement pipe is with thermo wires, high temperature fiber pipe, alundum tube from inside to outside successively, be characterized in, first bolt is built-in with the al-mg powder pearl, and second bolt is built-in with active card cover banding in the external diameter of the pipe of reinforcement pipe.
Base is provided with the shoulder dish line of protrusion, and described boss is equipped with has the gag of seeing fenestra, and the shoulder dish diameter of described gag is greater than the external diameter of boss, and described base outer end opening is a circular arc.Described alundum tube is provided with Fibre Bag outward, and reinforcement pipe bottom is stretched in the base.
The beneficial effects of the utility model are: utilize in first bolt to compress mode, nut screwing clamping makes the crushing of magnesium powder in a hole, along with nut is further tightened al-mg powder with thermo wires is pressed together, prevents to manage interior flame and emerges, and avoids terminal box to burn out.The active card cover acts on the sleeve pipe external diameter, makes card cover Gu tightly at the reinforcement external diameter of pipe with nut screwing clamping, reaches to prevent that rainwater from flowing in the stove from joint.Adopt one and have the gag of seeing fenestra, the shoulder dish of gag is greater than the external diameter of boss, prevent that rainwater from directly entering in the hole, a convex shoulder line is established on the plane on base again, make rainwater not in the base plane ostium, at furnace roof mounting hole position, the rainwater that prevents the mounting seat plane flows into burner hearth, in the outer at base middle part end opening design band circular arc, prevents that rainwater from entering, prolong reinforcement pipe on the thermopair, increase alundum tube intensity, prevent to install and use and produce the crack in the process, adopt Fibre Bag to be enclosed within outside the thermopair alundum tube in transportation, guarantee the rising explosion of thermocouple sheath local temperature and the time be unlikely to fall in the burner hearth, and can prolong thermopair serviceable life in fracture.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is the partial enlarged drawing of the utility model first bolt;
