The working principle is as follows:
two jointed pipes 103 at two sides are respectively inserted into two ends of a pipe hole 102 through a pushing block through pipe hole 303, so that the two jointed pipes 103 at two sides are mutually communicated with the pipe hole 102, the clamping and pressing communication effect of the pipe fitting is realized, which is a common technical means for the clamping and pressing communication of the existing pipe fitting, but after the clamping and pressing communication of the pipe fitting, the phenomena of water seepage in gaps, poor communication and easy washout of water pressure are easily generated, the clamping and pressing communication process of the pipe fitting is time-consuming and labor-consuming, fastening is needed by means of external tools, and for two pipe fittings of different models, specially customized and adapted jointed pipes are needed to be fixedly communicated, otherwise, the sealing effect is seriously influenced, in the invention, after the jointed pipes 103 at two sides are communicated with the pipe hole 102, the pushing blocks 301 at two sides of a connecting pipe 101 are simultaneously pushed towards the middle part, the pushing block 301 is pushed, the pushing ring 302 also moves along with the pushing block, therefore, during the process that the pushing and pressing ring 302 moves towards the inside of the pushing and pressing groove 201, pressure is applied to the rubber pressure ring layer 202 towards the pipe hole 102, so that the rubber pressure ring layer 202 is pressed and shrunk towards the pipe hole 102, the hemisphere sealing blocks 203 are pressed on the outer surfaces of the two sides of the connecting tubes 103, the size of the hemisphere sealing block 203 on the side close to the center of the pipe hole 102 is larger than that of the hemisphere sealing block 203 on the side far away from the center of the hemisphere sealing block 203, during the process that the two sides of the connecting tubes 103 are inserted into the pipe hole 102 at first, the two sides of the large pipe diameter are just inserted into the pipe hole 102 by the connecting tubes 103 and are subjected to resistance caused by the small-size hemisphere sealing blocks 203, and the small-diameter pipe can feel resistance when touching the large-size hemisphere sealing blocks 203, which determines that the device can adapt to pipe fittings with different pipe diameters to freely connect, and when the resistance is felt, the continuous insertion of the, the pushing and pressing ring 302 is inserted into the pushing and pressing groove 201 to press the rubber pressure ring layer 202, so that the hemispherical sealing block 203 is tightly attached to the surfaces of the two side jointed pipes 103, the hemispherical sealing block 203 is deformed and flattened, gaps between the two side jointed pipes 103 and the hemispherical sealing block 203 can be filled and sealed, water flows between the two side jointed pipes 103 and the pipe hole 102, a high-efficiency sealing effect is achieved, and the outward water seepage phenomenon can be effectively avoided, and the invention does not need to worry about the phenomenon that the pipe hole 102 and the two sides are impacted and separated by the jointed pipes 103 in the water feeding process, when the water flows through the pipe hole 102, the larger the water pressure is, the larger the pushing force close to the direction of the air pressure ring groove 401 is caused by the rubber pressure ring layers 202 on the two sides of the middle part of the pipe hole 102 is, the middle part of the rubber pressure ring layer 202 deforms towards the air pressure ring groove 401, at the moment, the reset spring 402 is compressed, the effect of recovering the initial position of the rubber compression ring layer 202 is realized, the air pressure in the air pressure ring groove 401 is increased, the air pressure in the reset spring 402 communicated with the air pressure ring groove 401 is also increased, the air pressure in the reset spring 402 causes pressure on the rubber sealing sheet 502, so that the rubber sealing sheet 502 deforms towards the direction of the sliding clamping block 503, the rubber sealing sheet 502 deforms to push the sliding clamping block 503 to be clamped into the clamping groove 504, and a limiting effect is generated on the pushing ring 302, so that the pushing ring 302 can ensure that enough pressure is always generated on the semispherical sealing block 203 and the semispherical sealing block 203, and two sides attached to the semispherical sealing block 203 are not easy to fall off and separate due;
the auxiliary seal mounting block 705 is rotated, under the action of the thread, the auxiliary seal mounting block 705 moves towards the thread annular groove 704 to further drive the auxiliary seal ring 706 to move towards the thrust ring guide inner groove 702, the thrust ring guide inner groove 702 plays a role in limiting and guiding the auxiliary seal ring 706, the auxiliary seal ring 706 moves towards the thrust ring guide inner groove 702, the auxiliary seal ring 706 utilizes an arc surface to generate a pushing effect towards the direction of the rubber pressure ring layer 202 on the auxiliary seal thrust sliding block 707, one side of the auxiliary seal thrust sliding block 707 close to the rubber pressure ring layer 202 is an inclined surface, the inclined surface enables the auxiliary seal thrust sliding block 707 to have different pressure effects on different areas of the rubber pressure ring layer 202, the area of the rubber pressure ring layer 202 close to the large-size hemispherical seal block 203 is pushed with a small deformation amount, the area of the rubber pressure ring layer 202 close to the small-size hemispherical seal block 203 is pushed with a large deformation amount, even if the sizes of the semispherical sealing blocks 203 which are subjected to the thrust effect of the auxiliary sealing thrust sliding blocks 707 are different, the semispherical sealing blocks can be simultaneously propped against the side walls of the two side jointed pipes 103 by the pushing force, so that the two side jointed pipes 103 obtain a multi-circle sealing effect, and the sealing performance is further enhanced.
