Abstract
The utility model relates to a steam pipe installing joint used for a hydrochloric acid tank used for heat treatment of a steel cord. The steam pipe installing joint used for the hydrochloric acid tank used for the heat treatment of the steel cord includes a pipe-shaped steam joint communicated with a steam conveying pipe, a pipe joint fixed on a heating device and a joint nut. A docking face of the pipe-shaped steam joint is in a disc-shaped structure. A groove is arranged in the docking face of the disc-shaped structure. After the joint nut is installed, a sealing layer is filled in an annular cavity and a groove formed between the joint nut and the pipe-shaped steam joint. According to the utility model, the sealing effect of the docking face is improved by arranging the groove in the docking face of the pipe-shaped steam joint and arranging the filling sealing layer. The occurrence of the steam leakage is prevented and the occurrence of corrosion caused by that corrosive liquid percolating through the docking face is also prevented. The service lifetime of the pipe joint is prolonged and the normality of the heat treatment temperature is guaranteed. The steam pipe installing joint used for the hydrochloric acid tank used for the heat treatment of the steel cord provided by the utility model is simple in structure, good in effect, long in service lifetime and small in maintenance volume. Therefore, the production cost and the maintenance cost can be reduced.
Description
Technical field:
The utility model relates to steel cord heat treatment steam connection and improves structure, is specifically related to the erection joint of a kind of steel cord heat treatment (hydrochloric acid trough) heating steam pipe.
Background technique:
The steam connection of steel cord hydrochloric acid trough heat treatment heating is a kind of parts of being corroded or leaking gas of being very easy to.Existing steam tube erection joint is that equipment carries embryonal structure, stainless steel.The hydrochloric acid trough temperature is about 60 °, and hydrochloric acid heats rear volatility, corrosivity is very strong.The frequent corrosion and damage of embryonal structure stainless steel connecting sleeve causes Lou steam and acid mist.Healthy, equipment to environment, operator impact.Air leak position also can cause component corrosion because acid solution flows out, and has further aggravated the damage progress of steam connection.In addition, cause heating-up temperature to reduce because leaking steam, affect thermal effectiveness.
Summary of the invention:
The utility model is to overcome deficiency and the defective that prior art exists, and the heat treatment heating steam pipe erection joint of a kind of steel cord salt pickling is provided.
Technological scheme: the heat treatment heating steam pipe erection joint of a kind of steel cord salt pickling, comprise the tubulose steam joint that is communicated with steam pipeline, be fixed on the pipe joint on the heating equipment, the arranged outside of pipe joint has outside thread, the center of described pipe joint is hollow structure, the hypomere of this hollow structure is non-threaded section, epimere is internal thread segment, and the diameter of this internal thread segment is outer thick interior thin cone structure; The end of steam joint is provided with the outside thread with conical internal thread section coupling.
Described non-threaded section internal diameter is greater than the internal diameter of the thinner end of conical internal thread end.
Described tubulose steam joint and pipe joint all adopt the teflon material.
The beneficial effects of the utility model: steam heating pipeline sealing extra-heavy, hydrochloric acid mist does not corrode link, has guaranteed the sealing of equipment reliability of operation and etchant gas.Prevent the appearance of steam leakage situation, prevent that also corrosion liquid from leaching interface and causing corrosion condition to occur, improve the working life of pipe joint, guarantee that heat treatment temperature is normal.The utility model is simple in structure, and is effective, long service life, and maintenance is little, thereby can save production cost and maintenance cost.
Description of drawings:
Fig. 1 is the pipe joint cross-sectional view.
Number in the figure 1 is pipe joint, and 2 is non-threaded section, and 3 is outside thread, and 4 is the conical internal thread section.
Embodiment:
Referring to Fig. 1, the heat treatment heating steam pipe erection joint of this steel cord salt pickling comprises the tubulose steam joint that is communicated with steam pipeline, is fixed on the pipe joint 1 on the heating equipment.The arranged outside of pipe joint 1 has outside thread 3.The center of pipe joint 1 is hollow structure, and the hypomere of this hollow structure is non-threaded section 2, and epimere is internal thread segment, and the diameter of this internal thread segment is outer thick interior thin cone structure, and namely the conical internal thread section 4.Described non-threaded section internal diameter is greater than the internal diameter of the thinner end of conical internal thread end.The end of steam joint is provided with the outside thread with conical internal thread section coupling, and both mate the sealing installation.Described tubulose steam joint and pipe joint all adopt the teflon material.
