DETAILED DESCRIPTION
[0020] The utility model will be further described in connection with the embodiment shown in the drawings:
[0021] As Figs. 1 to 4 Indicated, a kind of waterway adapter of integrated check valve, including connector body 1, the upper and lower two ends of the connector body 1 are equipped with two pipeline connection inner grooves 11 and pipeline connection boss 12 of different inner diameters respectively, the inside of the connector body 1 is hollow and can allow water to pass normally.The pipeline connection inner groove 11 and pipeline connection boss 12 are respectively different screw thread inner groove and outer thread of diameter.
[0022] When selecting a six-to-four joint, the user needs to select the appropriate model according to the specific pipe material and working pressure to ensure the matching and durability of the joint body 1 and the pipe. By using the pipe connection inner groove 11 and the pipe connection boss 12 with different diameters at both ends of the joint body 1, the connection problem between pipes of different diameters can be effectively solved, and the efficiency and reliability of the entire water system can be improved.
[0023] The joint body 1 is also provided with a sealing gasket support surface 14, and the surface of the sealing gasket support surface 14 is provided with a silica gel sealing gasket 3. The silica gel sealing gasket 3 is provided to ensure that there is no water leakage after the pipe is connected to the joint body 1.
[0024] In this embodiment, the joint body 1 is provided with a limiting boss 13, and the surface of the limiting boss 13 is provided with a one-way valve assembly 2, and the water outlet of the one-way valve assembly 2 is directed towards the pipe connection inner groove 11 or the pipe connection boss 12.
[0025] By changing the direction of the water outlet of the entire one-way valve assembly 2 towards the pipe connection inner groove 11 or the pipe connection boss 12, the user can easily select the anti-backflow direction of the waterway in the pipe, making the entire joint more adaptable.
[0026] The one-way valve assembly 2 includes a first valve body 21, a second valve body 22, a valve core element 23, and an elastic support structure 24. The first valve body 21 and the second valve body 22 are detachably connected by a buckle. The first valve body 21 is provided with a movable valve core element 23 inside. The top of the first valve body 21 is provided with a first limiting end face for blocking the sliding of the valve core element 23. The second valve body 22 is provided with an elastic support structure 24 inside for supporting the valve core element 23 to adhere to the first limiting end face of the first valve body 21.
[0027] The bottom inside of the first valve body 21 is provided with a first female buckle 211, and the top outside of the second valve body 22 is provided with a first male buckle 221. The first male buckle 221 can be buckled inside the first female buckle 211 after deformation.
[0028] Since the first valve body 21, the second valve body 22, and the valve core element 23 are all made of plastic material, they all have a certain deformation ability. The first male buckle 221 can be detachably buckled inside the first female buckle 211, which can facilitate the disassembly of the entire one-way valve assembly 2. Impurities or small particles in the waterway pipe are easily accumulated inside the one-way valve assembly 2 over time, so the quick-release mode can ensure subsequent maintenance and disassembly.
[0029] The elastic support structure 24 is a plurality of first support plates 241, first support columns 242 and metal springs 243. Each of the first support plates 241 is arranged on the inner wall surface of the second valve body 22 and faces the axis of the first support column 242. The converging ends of the plurality of first support plates 241 are provided with the first support column 242. The first support column 242 is hollow inside and connected to the bottom of the valve core element 23. The outer side of the first support column 242 clamps one end of the metal spring 243. The other end of the metal spring 243 is clamped to the bottom of the valve core element 23.
[0030] The first support plate 241, the first support column 242 and the second valve body 22 are integrally formed. When the water flow impacts the top of the valve core element 23, the valve core element 23 will have a downward movement trend and press the metal spring 243 to deform. In the deformation process of the metal spring 243, the valve core element 23 slides downward in the first valve body 21. The gap between the first limiting end surface at the top of the first valve body 21 and the top of the valve core element 23 becomes larger, and water continuously flows downward from the gap.
[0031] When the water flow impacts the bottom of the valve core element 23, no matter how large the impact force of the water flow is, the valve core element 23 will be subjected to the elastic force of the metal spring 243 and tightly adhere to the first limiting end surface at the top of the first valve body 21, so that the water flow is difficult to flow upward, thereby achieving the effect of preventing reverse flow.
[0032] The valve core element 23 includes a valve core body 231 and a valve core support column 232. The valve core support column 232 is slidably connected to the inside of the first support column 242. The bottom of the valve core body 231 clamps the end of the metal spring 243. The outer side surface of the valve core body 231 is provided with a first sealing ring 25, which adheres to the inner wall of the first valve body 21.
[0033] When the top surface of the valve core body 231 moves downward under the impact of the water flow, the valve core support column 232 slides downward in the first support column 242. In this process, the gap between the first sealing ring 25 on the outer side surface of the valve core body 231 and the inner wall of the first valve body 21 also becomes larger, so that water can normally flow downward from the top of the first valve body 21.
[0034] When the bottom of the valve core body 231 moves upward under the impact of the water flow, the first sealing ring 25 on the outer side surface of the valve core body 231 tightly adheres to the inner wall of the first valve body 21. At this time, the first sealing ring 25 is in a state of extrusion deformation. Water flowing upward from the entire connector body 1 cannot seep upward, further enhancing the anti-reverse flow effect of the entire one-way valve assembly 2.
[0035] The top outer side of the first valve body 21 is further provided with a second sealing ring 26, which is attached to the inner wall of the joint body 1. The second sealing ring 26 is always in a state of being extruded, and the second sealing ring 26 can prevent water from seeping between the outer wall of the entire one-way valve assembly 2 and the inner wall of the first valve body 21.
[0036] The working principle and use method of the utility model:
[0037] The pipe connection inner groove 11 and the pipe connection boss 12 at both ends of the joint body 1 are connected by pipelines with different diameters, which can effectively connect pipelines with different diameters, and then the outlet of the one-way valve assembly 2 is selected to face the pipe connection inner groove 11 or the pipe connection boss 12.
[0038] When the water flow impacts the top of the valve core element 23, the valve core element 23 will have a downward movement trend and will extrude the metal spring 243 to deform. During the deformation of the metal spring 243, the valve core element 23 slides downward in the interior of the first valve body 21, so that the gap between the first limiting end face at the top of the first valve body 21 and the top of the valve core element 23 will become larger, and the gap between the outer surface of the valve core body 231 and the inner wall of the first valve body 21 will also become larger, and water will continuously flow downward from this gap.
[0039] If the water flow impacts the bottom of the valve core element 23, regardless of the impact force of the water flow, the valve core element 23 will be subjected to the elastic force of the metal spring 243, so that the top is tightly attached to the first limiting end face at the top of the first valve body 21, and the first sealing ring 25 is in a state of extrusion deformation, and the water flowing upward from the entire joint body 1 cannot seep upward, thereby achieving the effect of preventing reverse flow.
[0040] The specific embodiments described in the present application are only illustrative of the spirit of the utility model. Those skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the scope defined by the appended claims.
