Figure 8Assembled effect drawing to pass the empty cylinder 2 through the hole drilled in the water tank side wall, one end of the empty cylinder 2 extends into the water tank, and the other end of the empty cylinder 2 is exposed outside the water tank, the external thread 10 is in contact with the hole in the water tank side wall, the sealing gasket ring 11 is in contact with the water tank side wall, the hexagonal limiting part 12 is tightly attached to the water tank side wall, using a wrench to tighten the hexagonal limiting part 12, manually attaching the nut 1 to the external thread 10, and then using another wrench to tighten the nut 1, so that the nut 1 is screwed into the external thread 10, the nut 1 is screwed along the external thread 10 into the outer wall of the empty cylinder 2, the nut 1 is tightly attached to the water tank side wall by cooperating with the external thread 10, the tightly tightened nut 1 extrudes the sealing gasket ring 11 against the water tank side wall, the nut 1 causes the sealing gasket ring 11 to be pressed downward on the upper end of the hexagonal limiting part 12, the lower end of the nut 1 is tightened to cause the upper end of the sealing gasket ring 11 to be pressed downward tightly, the nut 1 causes the lower end of the sealing gasket ring 11 to be pressed tightly on the upper end of the hexagonal limiting part 12, the external thread 10 enables the nut 1 to be screwed into the periphery of the empty cylinder 2 to tightly contact the sealing gasket ring 11 with the hexagonal limiting part 12, the upper and lower ends of the sealing gasket ring 11 are respectively extruded and contracted by the nut 1 and the hexagonal limiting part 12 to elastically deform, the sealing gasket ring 11 generates a rebound force to respectively expand and open the nut 1 and the hexagonal limiting part 12, the sealing gasket ring 11 is tightly inlaid between the nut 1 and the hexagonal limiting part 12, and relies on the elasticity of the sealing gasket ring 11 to tightly contact the nut 1 and the hexagonal limiting part 12 respectively, the external force borne by the nut 1 and the hexagonal limiting part 12 will be transmitted to the surface of the sealing gasket ring 11, the sealing gasket ring 11 itself deforms elastically to cause extrusion and contraction and expansion and opening processes to consume energy brought by external force, the external force is weakened, and the external force will be absorbed by the sealing gasket ring 11, the supporting ring 6 away from the one end of the spring 7 is uniformly bonded with the buffer ring 5, the inner thread 3 located outside the buffer ring 5 is provided in the inner wall of the empty cylinder 2, the sealing gasket ring 11 plays a buffering role with the hexagonal limiting part 12 to the nut 1, and the hollow pipe is screwed into the inner thread 3 at one end of the empty cylinder 2 away from the hexagonal limiting part 12, the hollow pipe is screwed into the inner thread 3 inside the empty cylinder 2 adjacent to the outside of the buffer ring 5, so that the hollow pipe is connected with the water tank through the sealing lock, and the sealing gasket ring 11 fills the gap between the water tank side wall and the empty cylinder 2 to avoid water leakage.
[0022] When the water flow flows through the hollow pipe into the inside of the empty cylinder 2, no matter which side the water flow flows, the water flow will flow along the surface of the elastic sheet 9 inside the empty cylinder 2, the elastic sheet 9 is elastically deformed by the water flow, the elastic sheet 9 changes from the original flat state to the curved arch state, the elastic sheet 9 will have the maximum curvature after being stressed to the maximum degree, the scouring force of the water flow is concentrated on the surface of the elastic sheet 9, the scouring force of the water flow is absorbed by the surface of the elastic sheet 9, the elastic sheet 9 causes the sleeve ring 8 to slide along the inner wall of the empty cylinder 2, the two springs 7 are supported by the corresponding supporting ring 6 to maintain the effect of being installed inside the empty cylinder 2, the sleeve ring 8 causes the upper and lower springs 7 to stretch and contract respectively (the spring 7 will have a restoring force when stretching and contracting), the upper and lower springs 7 change states oppositely (when any one of the springs 7 is stretched, the opposite spring 7 is contracted), the supporting ring 6 is used to support the corresponding spring 7 to be stably placed inside the empty cylinder 2, the buffer ring 5 absorbs the impact force of the stretching and contracting spring 7 to reduce the damage to the supporting ring 6, the elastic sheet 9 consumes the scouring force transmitted from the water flow during the sliding process, the scouring force of the water flow on the inner wall of the empty cylinder 2 is weakened, which can buffer the water flow inside the empty cylinder 2, avoid the water pressure inside the hollow pipe from causing the connection between the sealing lock and the hollow pipe to crack and leak, and reduce the water pressure to damage the sealing lock.
[0023] When the water flow changes direction, the elastic sheet 9 also changes direction to slide along the inner wall of the empty cylinder 2, the direction of the sliding of the elastic sheet 9 is consistent with the direction of the water flow, with the change of the water flow, the elastic sheet 9 will slide up and down along the inner wall of the empty cylinder 2 under the scouring force of the water flow, multiple water conveying channels 4 in the same horizontal plane form a row of water conveying channels 4, the upper and lower rows of water conveying channels 4 are separated by a distance, the length of the spring 7 is less than the height of the water conveying channel 4, when the water flow flows through the empty cylinder 2, the elastic sheet 9 causes the upper and lower springs 7 to rotate and contract to move to the inside of the multiple water conveying channels 4 in the same row, the elastic sheet 9 slides in the middle of the empty cylinder 2 to the inside of the corresponding multiple water conveying channels 4 on the same side, there is a gap between the elastic sheet 9 and the adjacent water conveying channel 4, the water flow will flow through the gap and enter the adjacent water conveying channel 4, so that the water flow can bypass the elastic sheet 9, and the water flow flows from one end of the empty cylinder 2 to the other end of the empty cylinder 2, achieving the effect of water flow circulation inside the empty cylinder 2.
[0024] When there is no water flow through the empty cylinder 2, the spring 7 will automatically reset the elastic sheet 9 to the inside of the upper and lower rows of water conveying channels 4, which can automatically control the conduction and closing of the inside of the empty cylinder 2.
[0025] In combination with the above effects, the improved sealing lock uses the structure of the improved screw thread upper and lower fastening bottom plus sealing gasket ring 11 to replace the previous process, making the installation of the liquid tank more convenient and fast, without the need for welding process and the use of welding method to connect the hollow pipe with the water tank. Instead, the sealing gasket ring 11 and the elastic sheet 9 form a buffer inside the hollow cylinder 2, which will not cause the deformation of the high-temperature container during welding and the leakage caused by false welding, thereby greatly improving the technical and construction efficiency.
