High-temperature-resistant antifouling ceramic ignition needle and preparation method thereof
The invention belongs to the technical field of ignition needles, and particularly relates to a high-temperature-resistant antifouling ceramic ignition needle and a preparation method thereof.The high-temperature-resistant antifouling ceramic ignition needle comprises an ignition guide column, the lower end of the outer side of the ignition guide column is sleeved with a high-temperature-resistant shell, a filling layer is arranged between the ignition guide column and the high-temperature-resistant shell, and the outer side of the high-temperature-resistant shell is movably sleeved with a positioning disc; the lower side of the positioning disc is connected with a guide sleeve, external threads are arranged on the outer side of the high-temperature-resistant shell, internal threads are arranged in an inner cavity of the guide sleeve, the high-temperature-resistant shell is in threaded connection with the guide sleeve, a locking nut is in threaded connection with the outer side of the high-temperature-resistant shell, and the upper end of the locking nut is attached to the upper end of the guide sleeve. When the device is installed, the length of the extending end of the ceramic ignition needle can be adjusted by adjusting the length of the ignition guide column and the length of the portion, extending out of the positioning disc, of the high-temperature-resistant shell, and therefore the device can have more application space.
本发明属于点火针技术领域，具体为一种耐高温防污的陶瓷点火针及其制备方法，包括点火导柱，所述点火导柱的外侧下端套设有耐高温外壳，所述点火导柱与耐高温外壳之间设置有填充层，所述耐高温外壳的外侧活动套设有定位盘，所述定位盘的下侧连接有导向套，所述耐高温外壳的外侧设置有外螺纹，所述导向套的内腔中设置有内螺纹，所述耐高温外壳与导向套螺接，所述耐高温外壳的外侧螺接有锁紧螺母，所述锁紧螺母的上端与导向套的上端贴合，本发明在安装本装置时，通过调节点火导柱和耐高温外壳伸出定位盘长度，即可对陶瓷点火针的伸出端长度进行调节，进而可以使其拥有更多的适用空间。
