DETAILED DESCRIPTION
[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.
[0017] like Figures 1 to 4As shown, a one-way valve assembly that is easy to replace includes a valve body 1 and a valve core 2, the valve body 1 is provided with an accommodating groove 3, and the valve body 1 is provided with a plurality of threaded through holes 4 that are connected to the accommodating groove 3, the accommodating groove 3 is provided with a mounting ring 5, and a sealing ring 6 is provided on one side of the mounting ring 5, the valve core 2 is provided with a through groove, and a conducting member is provided in the through groove, the valve core 2 is inserted into the accommodating groove 3 of the valve body 1 and abuts against the mounting ring 5, the outer side of the valve core 2 is provided with a plurality of mounting holes 7, and the threaded through holes 4 are threadedly connected with mounting bolts 8 that can be connected to the mounting holes 7.
[0018] The working principle of the one-way valve assembly that is easy to replace in the present invention is achieved by the mutual cooperation of the valve body 1 and the valve core 2. Figures 1 to 4 As shown, when the one-way valve fails and needs to be repaired and replaced, the staff twists the mounting bolt 8, the mounting bolt 8 separates from the mounting hole 7 and moves outward along the threaded through hole 4, thereby releasing the connection between the mounting bolt 8 and the mounting hole 7, so that the valve core 2 can be separated from the valve body 1 and can be pulled out of the valve body 1, and then the staff inserts the replaced valve core 2 into the accommodating groove 3 of the valve body 1 and aligns the mounting hole 7 with the mounting bolt 8 on the threaded through hole 4. Finally, the staff tightens the mounting bolt 8, and the mounting bolt 8 moves inward along the threaded through hole 4 and connects with the mounting hole 7, thereby completing the installation of the valve core 2. Compared with the traditional one-way valve, the one-way valve assembly that is easy to replace is convenient for replacing a damaged valve core 2, and there is no need to replace the valve body 1 and the valve core 2 at the same time, thereby reducing the maintenance and replacement cost.
[0019] Specifically, the notches at both ends of the accommodating groove are provided with internal threads, and the accommodating groove is provided with a plurality of arc-shaped limit strips 9 on one side of the mounting ring 5, and the plurality of arc-shaped limit strips 11 are evenly arranged in the accommodating groove and form a plurality of positioning grooves 10, wherein the sealing ring 6 is between the valve body 1 and the mounting ring 5, and the sealing ring 6 is between the arc-shaped limit strip 9 and the mounting ring 5, wherein the outer circumference of the valve core 2 is evenly provided with a plurality of guide strips 11, and the plurality of mounting holes 7 are correspondingly arranged in the middle of the plurality of guide strips 11, as shown in FIG. Figures 1 to 4 As shown, the guide strip 11 of the valve core 2 is inserted into the positioning groove 10 to facilitate the alignment of the mounting hole 7 on the valve core 2 with the mounting bolt 8 of the threaded through hole 4, so that the mounting hole 7 can be quickly positioned and the mounting bolt 8 can be easily connected to the mounting hole 7. It should be noted that the spacing between the threaded through groove and the mounting ring 5 is equal to the spacing between the mounting hole 7 and the mounting ring 5, so that after the valve core 2 is inserted into the valve body 1, the positioning hole is aligned with the threaded through hole 4, and after the valve core 2 is inserted into the valve body 1, it is abutted against the sealing ring 6 on one side of the mounting ring 5, quickly positioning and sealing the gap between the valve core 2 and the mounting ring 5, thereby improving the sealing performance of the valve core 2 and the valve body 1.
[0020] Furthermore, a first conducting portion 12 and a second conducting portion 13 are provided in the through groove, and an inclined portion 14 is provided between the first conducting portion 12 and the second conducting portion 13, the diameter of which gradually increases from the first conducting portion 12 to the second conducting portion 13, and a bracket 15 is provided in the second conducting portion 13. Furthermore, the conducting member includes a conducting head 16, a push rod 17 and a compression spring 18, one end of the push rod 17 is connected to the conducting head 16, and the push rod 17 is slidably connected to the bracket 15, the conducting head 16 is connected to the bracket 15 through the compression spring 18 and the compression spring 18 is sleeved on the push rod 17, and the conducting head 16 structure corresponds to the inclined portion 14, as shown in FIG. Figures 1 to 4 As shown, after the conducting head 16 is impacted by the water flow from the first conducting part 12, the compression spring 18 is compressed, and the conducting head 16 moves toward the bracket 15. The push rod 17 moves along the bracket 15 with the conducting head 16, so that a gap for water flow is generated between the conducting head 16 and the inclined part 14, thereby making the valve core 2 unidirectional. An opening can be set on the bracket 15 so that water flows through the bracket 15 and flows along the second conducting part 13.
