Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3 As shown, a lifting valve for a regenerative waste gas incinerator includes a connecting pipe body 1, a lifting valve body 101 at the connection of the connecting pipe body 1, and a branch pipe 2 at the front end of the lifting valve body 101. A pressure relief valve body 201 is provided on the upper surface of the branch pipe 2, and a threaded pressure adjusting rod 204 is spirally installed on the upper surface of the pressure relief valve body 201. The advantage of this configuration is that, by setting the pressure relief valve body 201, the pressure can be monitored before the waste gas enters the lifting valve body 101, so as to avoid the pressure in the pipeline suddenly rising during the operation of the waste gas incinerator and to open the pressure relief valve in time to protect the safety of the equipment.

[0021] Furthermore, a pressure adjusting knob 205 is provided on the upper surface of the threaded pressure adjusting rod 204, and a compression spring 206 is provided on the lower surface of the threaded pressure adjusting rod 204. The advantage of this arrangement is that the pressure relief pressure of the pressure relief valve body 201 can be adjusted according to the pressure resistance of the equipment by setting the threaded pressure adjusting rod 204.

[0022] Furthermore, a pressure relief pipe 202 is provided on the outer surface of the pressure relief valve body 201, and an alarm device 203 is installed at the end of the pressure relief pipe 202. The advantage of this setting is that, through the setting of the alarm device 203, an alarm can be issued when the pressure relief valve body 201 is depressurized, so as to ensure the safe use of the equipment.

[0023] like Figure 4 As shown, a threaded groove 302 is provided on the inner wall surface of the upper end of the branch pipe 2, and a connecting ring 303 is spirally installed on the inner surface of the threaded groove 302. A filter screen 304 is provided on the inner surface of the connecting ring 303, and the filter screen 304 is made of activated carbon. The advantage of this setting is that the dust inside the connecting pipe body 1 can be filtered by the filter screen 304, so as to avoid dust clogging the pressure relief valve body 201 and affecting the normal use of the equipment.

[0024] Further, the inner wall bottom surface of the branch pipe 2 is provided with a support ring 3, and the upper surface of the support ring 3 is magnetically installed with a magnetic filter ring 301. The advantage of this setting is that the magnetic impurities in the exhaust gas can be adsorbed through the setting of the magnetic filter ring 301, thereby reducing the purification pressure of the filter screen 304.

[0025] Working principle: when using the poppet valve for the heat accumulating type exhaust gas incinerator, first, when treating the exhaust gas, the exhaust gas will first pass through the branch pipe 2 into the inside of the pressure relief valve body 201; before entering the inside of the pressure relief valve body 201, the exhaust gas will be filtered by the magnetic filter ring 301 and the filter screen 304 to avoid impurities blocking the pressure relief valve body 201 and affecting the use of the equipment. After the pressure of the exhaust gas is normal, the exhaust gas will be treated by the poppet valve body 101; if the gas pressure is too large, the gas will lift the pressure relief valve body 201, so that the exhaust gas enters the alarm device 203 through the pressure relief pipe 202 to alarm. This is the working principle of the poppet valve for the heat accumulating type exhaust gas incinerator.
