Embodiment
Below in conjunction with drawings and Examples a kind of retort master of the present utility model is returned the seal valve of using on the smoke pipe and be described in further detail, but not as the foundation of the utility model being done any restriction.
Embodiment.A kind of retort master of the present utility model returns the seal valve of using on the smoke pipe, as shown in Figure 1.Comprise and lead back the valve body 2 that smoke pipe 1 is communicated with; One end of valve body 2 is connected with smoke vent 4 on the charing furnace wall 3, and the other end of valve body 2 is connected through attachment screw 5 and external sealed lid 6; External sealed lid 6 is provided with slidably U-shaped pull bar 7, and the end of U-shaped pull bar 7 is provided with interior sealing cover 8.Be equipped with auricle 9 on described valve body 2 and the external sealed lid 6, valve body 2 is connected through attachment screw 5 with the auricle 9 that external sealed covers on 6.
Described external sealed lid 6 comprises outer heat insulating tube 10 as shown in Figure 2, is provided with sleeve pipe 21, fire-resistant mud layer 11 and fire-resistant cotton layer 12 in the outer heat insulating tube 10; Outer heat insulating tube 10 is provided with outer cover plate 13, is provided with the cotton pad 14 of enclosing cover sealing in the outer cover plate 13, and outer cover plate 13 is provided with nut or thread 15, is provided with sealing hoop pad 16 in nut or the thread 15, is rotary with bleed screw 17 on nut or the thread 15.U-shaped pull bar 7 is through in the hole of bleed screw 17.
