[0030] Furthermore, the valve pipe 1 is connected to the delivery pipe 2, the holes of the connecting bolts of the first flange 1.1 are aligned with the holes of the connecting bolts of the second flange 2.1, the convex ring 1.2 on the valve pipe 1 is stuck in the groove 2.2 of the delivery pipe 2 for sealing, and then the sealing rubber ring 4 is installed to seal the gap between the first flange 1.1 and the second flange 2.1, and the gap between the first flange 1.1 and the second flange 2.1 is sealed by the sealing rubber ring 4 to prevent the loss of fluid in the pipeline.

[0031] It has a good sealing effect. The valve pipe 1 and the delivery pipe 2 are first fastened by the sealing component 3, and then the valve pipe 1 and the delivery pipe 2 are locked by the bolt component 5. The bolt component 5 is further locked by the locking groove 3.6.1 of the sealing component 3, so that the valve pipe 1 and the delivery pipe 2 are more tightly connected to avoid leakage of the fluid in the pipe.

[0032] More specifically, the sealing assembly 3 includes a swivel seat 3.1, a swivel plate 3.2, a swivel block 3.3, a threaded rod 3.4, a swivel handle 3.5, a pressure plate 3.6 and a semicircular block 3.7, wherein the base of the swivel seat 3.1 is fixedly mounted on an end face of the first flange 1.1 away from the second flange 2.1, one end of the swivel plate 3.2 is rotatably mounted on the swivel seat 3.1, both ends of the swivel seat 3.1 are provided with a swivel shaft, the other end of the swivel plate 3.2 is rotatably mounted on one end of the swivel block 3.3, the hole of the swivel plate 3.2 is rotatably sleeved on the swivel shaft of the swivel seat 3.1 and is rotatably connected, one end of the threaded rod 3.4 is rotatably mounted on the other end of the swivel block 3.3, the swivel handle 3.5 is fixedly mounted on the threaded rod 3.4, the top thread of the pressure plate 3.6 is mounted on the threaded rod 3.4, the pressure plate 3.6 can be screwed in or out by the rotation of the threaded rod 3.4, and the pressure plate 3.6 can be screwed in or out by the rotation of the pressure plate 3.6 The pressing plate 3.6 is screwed in or out so that the first flange 1.1 and the second flange 2.1 are pressed tightly. The semicircular block 3.7 is fixedly mounted on the side of the pressing plate 3.6 facing the second flange 2.1, and the semicircular block 3.7 is located in the positioning groove 2.3. The semicircular block 3.7 is installed in the positioning groove 2.3. When the threaded rod 3.4 rotates, the semicircular block 3.7 clamps the positioning groove 2.3 to prevent the pressing plate 3.6 from rotating with the rotation of the threaded rod 3.4, thereby ensuring the screwing in or out of the pressing plate 3.6. Locking grooves 3.6.1 are provided on both sides of the pressing plate 3.6. There is a gap in the locking grooves 3.6.1. Connecting holes 3.6.2 are provided on both sides of the pressing plate 3.6. The connecting holes 3.6.2 are located at the locking grooves 3.6.1. The connecting holes 3.6.2 are used for bolts to pass through.

[0035] Furthermore, the bolt 5.1 is threadedly installed in the threaded holes of the first flange 1.1 and the second flange 2.1, and the bolt 5.1 passes through the connecting hole 3.6.2. When the bolt 5.1 and the nut 5.3 are screwed in and connected, the locking groove 3.6.1 of the pressure plate 3.6 sinks and is squeezed and deformed, and elastic force is generated inside. This elastic force will make the locking groove 3.6.1 try to restore its original state, thereby generating continuous axial tension, preventing the bolt from loosening due to vibration or other dynamic loads, and evenly distributing the pressure of the bolt head or nut 5.3 on the connected parts by increasing the contact area, avoiding local excessive pressure from causing material damage, and at the same time enhancing the stability and safety of the bolt connection and extending the service life of the connection part.

Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
