本发明具有在线自动排污功能的喷嘴装置， 其工作原理和自清洗过程如下所述： ( 1 ) 正常工作状态下，所述的导流器 18的锥形面在所述弹簧 15的弹性力作用下与所 述喷嘴外壳 14下端的锥形面压紧配合， 用以产生圆锥形雾化喷射效果。 水流经过所述外 套 1上的进口水 7、 出水口 25、 导管 24并通过所述直角连通构件 22的侧端口和下端口进 入所述的喷嘴芯体 20， 再经所述喷嘴芯体 20下端锥面上设置的侧孔 19和导流槽 26由喷 水孔 17喷出； 由于所述导流槽 26与喷嘴外壳 14内腔的锥面间隙较小， 所以， 在冷却过 程中， 随水进入喷嘴芯体 20的颗粒杂质会沉积在导流器 18的外侧。 The invention has a nozzle device for online automatic sewage discharge function, and the working principle and the self-cleaning process are as follows: (1) Under normal working conditions, the tapered surface of the deflector 18 acts on the elastic force of the spring 15 The lower surface is press-fitted with the tapered surface of the lower end of the nozzle housing 14 to produce a conical atomizing spray effect. Water flows through the inlet water 7, the water outlet 25, the conduit 24 on the outer casing 1 and enters the nozzle core 20 through the side port and the lower port of the right angle communication member 22, and passes through the lower end of the nozzle core 20 The side hole 19 and the guide groove 26 provided on the tapered surface are sprayed The water hole 17 is ejected; since the flow gap between the guide groove 26 and the inner cavity of the nozzle housing 14 is small, particulate impurities that enter the nozzle core 20 with water are deposited on the deflector 18 during cooling. The outside.
(2) 当清洗喷嘴时，所述内套 2上的送气孔 5给气缸送入高压空气并同时由排气孔 6 排气， 使所述的活塞 3下移， 并带动活塞杆 4以及压盘 10下移， 所述压盘 10的位移通过 顶杆 12传递至喷嘴外壳 14， 由于气缸外套 1与所述的腔体 9固定， 且腔体 9又通过直角 连通构件 22与喷嘴芯体 20相固定， 因此压盘 8的位移导致所述喷嘴外壳 14与喷嘴芯体 18之间产生相对位移，从而使弹簧 15压缩，迫使所述导流器 18的锥面与喷嘴外壳 14内腔 的锥形面间产生较大间隙， 这时积聚在导流器 18周围的颗粒杂质就会随冷却水经喷水孔 17喷出， 完成喷头的在线冲洗工作。  (2) When the nozzle is cleaned, the air supply hole 5 on the inner sleeve 2 feeds the high pressure air to the cylinder and simultaneously exhausts the air vent 6 to move the piston 3 downward, and drives the piston rod 4 and the pressure. The disk 10 is moved downward, and the displacement of the platen 10 is transmitted to the nozzle housing 14 through the ram 12, since the cylinder casing 1 is fixed to the cavity 9, and the cavity 9 passes through the right-angle communicating member 22 and the nozzle core 20 again. The phase is fixed so that the displacement of the platen 8 causes a relative displacement between the nozzle housing 14 and the nozzle core 18, thereby compressing the spring 15, forcing the cone of the deflector 18 and the cone of the nozzle housing 14 A large gap is formed between the shapes, and at this time, the particulate impurities accumulated around the deflector 18 are ejected along with the cooling water through the water spray hole 17, and the in-line flushing operation of the nozzle is completed.
(3)冲洗工作完成后， 所述内套 2上的排气孔 6给气缸送入髙压空气并同时由送气孔 5排气， 使所述的活塞 3通过弹簧 15的作用力复位， 并使所述导流器 18的锥面与喷嘴外 壳 14内腔的锥面恢复至压紧状态。 . 本发明的具有在线自动排污功能的喷嘴装置， 其技术优势在于- (3) After the flushing operation is completed, the exhaust hole 6 in the inner sleeve 2 feeds the cylinder with the pressurized air and at the same time is exhausted by the air supply hole 5, so that the piston 3 is reset by the force of the spring 15, and The tapered surface of the deflector 18 and the tapered surface of the inner cavity of the nozzle housing 14 are returned to a compressed state. The technical advantage of the nozzle device with online automatic sewage function of the invention is that -
1. 喷嘴的清洗不需停机、不需拆卸、 更不需人工操作， 自行在线完成， 既提高了生产 效率， 又降低了人工作业强度； 1. The cleaning of the nozzle does not need to be stopped, does not need to be disassembled, and does not need manual operation. It is completed online, which not only improves the production efficiency, but also reduces the manual operation intensity;
2. 喷嘴的清洗通过气动方式完成， 可实现清洗过程的电子控制和远程控制，不仅使喷 嘴清洗自动化， 而且大大提高了喷嘴的工作效果。  2. The cleaning of the nozzle is done pneumatically, which can realize the electronic control and remote control of the cleaning process, which not only automates the nozzle cleaning, but also greatly improves the working effect of the nozzle.
