when the industrial wastewater conveying device is used, when industrial wastewater is required to be conveyed, the inserting pipe 2 can be directly inserted into the right end of the connecting valve 1, the air pressure ring 13 can be extruded and deformed when the inserting pipe 2 is inserted into the connecting valve 1, namely, the air pressure inside the air pressure ring 13 is further enhanced, so that the internal air pressure is conveyed into the U-shaped groove 12 through the opening on the inner side of the air pressure ring, when the air pressure inside the U-shaped groove 12 is increased, the clamping block 14 on the right side of the air pressure ring is pushed to move inwards, namely, when the inserting pipe 2 is connected with the connecting valve 1, the clamping block 14 can be clamped into the clamping groove 15 to realize automatic connection, the device is different from manual complicated connection in the prior art, the convenience for connecting the water pipe and the connecting valve 1 is greatly improved, and when the industrial wastewater is conveyed after the inserting pipe 2 is connected with the connecting valve 1, the industrial wastewater is accelerated due to the conveying radius when the industrial wastewater passes through the pressure ring 21 of the inserting pipe, the transmission speed of the industrial wastewater passing through the pressure ring 21 is higher than that in the insertion pipe 2, that is, the industrial wastewater is in a jet shape when leaving the insertion pipe 2, so that the pressure of the industrial wastewater on the outer side of the end part of the insertion pipe 2 is greatly reduced, the industrial wastewater can be effectively prevented from permeating into a connecting gap between the insertion pipe 2 and the connecting valve 1 through water pressure, the sealing effect can be preliminarily realized, and the industrial wastewater is prevented from leaking through the gap between the insertion pipe 2 and the connecting valve 1; when the industrial wastewater passes through the pressure ring 21 at the outer end of the insertion pipe 2, a large compression force is generated to the industrial wastewater due to pressure, so that the pressure in the inner cavity of the insertion pipe starts to increase, namely the sealing ring 3 in the insertion pipe is extruded outwards through the air release ring 22 gradually, and finally the sealing ring 3 is separated from the air release ring 22 and enters the sealing groove 17 in the connecting valve 1, and the outer surface of the sealing ring 3 is tightly attached to the inner wall of the sealing groove 17 along with the gradual action of the pressure, so that the connection between the insertion pipe 2 and the connecting valve 1 can be further sealed in the process of conveying the industrial wastewater, the sealing and isolating effects are further improved, and meanwhile, when the sealing ring 3 is separated from the air release ring 22 and starts to reset, the pull ropes 34 at the two ends of the air release ring 22 pull the blocking strip 32, so that the blocking strip 32 gradually slides towards the outer side of the air pressure groove 31 in the transportation process of the industrial wastewater, the inner side of the conical rubber gasket 33 is finally communicated with the air pressure groove 31, namely, the air pressure in the air pressure groove 31 can gradually push the conical rubber gasket 33 to move outwards and is finally attached to the inner wall of the sealing groove 17, the joint of the plug-in pipe 2 and the connecting valve 1 is sealed, the industrial wastewater is prevented from leaking, the joint of the plug-in pipe 2 and the connecting valve 1 can be effectively protected from being corroded, and meanwhile, the natural environment is protected; when the catching block 14 moves to the end of the catching groove 15, the auxiliary ring 18 pushed to the inner end thereof is pressed, the inner air pressure thereof is transmitted into the air pressure groove 31 when the auxiliary ring 18 is pressed, even if the pressure value of the air pressure groove 31 is further increased, the conical rubber pad 33 can be ensured to be completely attached to the inner wall of the sealing groove 17 to realize the sealing effect, the conical rubber pad 33 can not be penetrated out due to the insufficient pressure value of the air pressure groove 31 is avoided, meanwhile, a part of pressure is extruded to the memory elastic sheet 35 at the lower end of the pressure groove, the memory elastic sheet 35 is forced to slide outwards and be inserted into the wall of the air release ring 22, the great improvement sealing ring 3 and the joint strength who loses between the ring 22, produce great pressure to the junction of sealing ring 3 and the ring 22 that loses heart when avoiding water pressure great and lead to breaking away from between the two and can't effectively accomplish the sealed between spigot pipe 2 and the connecting valve 1.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
