[0051] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0052] like Figure 1-Figure 3 A new flow meter shown includes:

[0053] The lower joint 2 is formed with an adjustment reserved groove 21, and a through hole 22 is opened at the bottom end of the adjustment reserved groove 21. The lower joint 2 is also formed with a connecting pipe end 23, which is used to connect the branch water pipe.

[0054] The mounting seat 1 is formed with an insertion portion 11, and a sealing portion 12 is formed on the bottom edge of the insertion portion 11. The insertion portion 11 is movably inserted into the adjustment reserved groove 21, and the sealing portion 12 seals the insertion portion 11 and the adjustment reserved groove 21 to prevent water from flowing directly from the water distribution pipe through the lower joint 2 into the branch water pipe.

[0055] The valve core 3 is inserted into the mounting seat 1 , and a water outlet pipe 31 is formed at the lower end of the valve core 3 , and the water outlet pipe 31 is movably placed in the through hole 1 22 .

[0056] The flow meter assembly 4 is connected to the upper end of the valve core 3 .

[0057] During installation, first screw the end of the lower joint 2 where the adjustment reserved groove 21 is located to one side of the water distribution pipe, and make the pipe end 23 of the lower joint 2 face outward so that the pipe end 23 can be connected to the branch water pipe.

[0058] Then, the mounting base 1 is screwed onto the side of the water distribution pipe opposite to the lower joint 2, and the insertion portion 11 of the mounting base 1 can be inserted into the adjustment reserved groove 21, thereby achieving the connection between the mounting base 1 and the lower joint 2.

[0059] Because the specifications and sizes of water distribution pipes used by each household may vary depending on the actual situation of the user, the specifications and sizes of flow meter water distributors sold on the market are generally fixed, so size mismatches often occur during installation, affecting the installation and use effect.

[0060] The insert portion 11 is provided with a water diversion port 13, the valve core 3 is provided with a water inlet 33, and the outlet pipe 31 is formed with a water outlet channel 32, which is connected to the water inlet 33. When the water diversion port 13 and the water inlet 33 are connected, the fluid in the water diversion pipe can be introduced into the branch water pipe.

[0061] When the sealing portion 12 moves in the adjustment reserved groove 21, the end of the water outlet pipe 31 is always placed in the through hole 1 22 to ensure that the water flowing out through the water outlet pipe 31 can directly flow into the branch water pipe.

[0062] Since the sealing portion 12 at the bottom end of the insertion portion 11 can move in the adjustment reserved groove 21, the distance between the mounting seat 1 and the lower joint 2 can be changed by adjusting the depth of the insertion portion 11 inserted into the adjustment reserved groove 21, thereby facilitating the installation of the flow meter in this technical solution on water pipes of different specifications.

[0063] It should be noted that when the inserting portion 11 moves in the adjustment reserved groove 21 , the sealing portion 12 should always be located in the adjustment reserved groove 21 to ensure that the sealing portion 12 can provide a sufficient sealing effect.

[0064] Furthermore, a sealing ring groove 14 is formed on the sealing portion 12 , and a sealing ring 141 is disposed in the sealing ring groove 14 .

[0065] When the sealing portion 12 extends into the reserved adjustment groove 21 , the sealing ring 141 is used to seal the gap between the reserved adjustment groove 21 and the sealing portion 12 , so that the reserved adjustment groove 21 is not directly connected to the interior of the water distribution pipe.

[0066] like Figures 1-6 As shown, a screw connection groove 15 is formed on the mounting seat 1 , and a valve seat 35 is formed on the upper end of the valve core 3 , and the valve seat 35 is screwed into the screw connection groove 15 .

[0067] The valve core 3 also has a water retaining portion 34 formed thereon. A second sealing ring groove 6 is formed at the upper end of the water retaining portion 34, and a second sealing ring 61 is disposed within the second sealing ring groove 6. A third sealing ring groove 7 is formed at the lower end of the water retaining portion 34, and a third sealing ring 71 is disposed within the third sealing ring groove 7. The second sealing ring 61 and the third sealing ring 71 further enhance the sealing effect of the water retaining portion 34.

[0068] A sealing ring 4 82 is sleeved on the outer side of the valve core 3, and a sealing ring groove 4 81 is formed on the inner side of the mounting seat 1, and the sealing ring 4 82 is partially placed in the sealing ring groove 4 81, so that the sealing ring groove 4 81 can fix the position of the sealing ring 4 82. The sealing ring 4 82 is used to prevent water from flowing upward out of the mounting seat 1.

[0069] The upper end of the water retaining portion 34 is recessed to form a relief area 8. This relief area 8 prevents the sealing ring 24 82 from obstructing the movement of the valve core 3 as the valve core 3 moves within the mounting seat 1. Furthermore, when the sealing ring 24 82 abuts the upper end of the water retaining portion 34, it limits further upward movement of the valve core 3, thereby preventing the user from twisting the valve core 3 too far and causing the valve core 3 to separate from the mounting seat 1.

[0070] When the valve seat 35 is inserted into the bottom end of the first screw groove 15, the water retaining portion 34 blocks the water diversion port 13. At this time, the second sealing ring 61 and the third sealing ring 71 respectively seal the upper and lower ends of the water diversion port 13, thereby preventing the water diversion port 13 from communicating with the water inlet 33, thereby preventing water from flowing through the flow meter into the branch water pipe.

[0071] When the valve seat 35 is rotated to move the valve core 3 as a whole upward to the upper end of the screw groove 15, the water inlet 33 will move with the valve core 3 and connect with the water outlet 13, so that the water in the water distribution pipe can enter the water outlet channel 32 and flow to the branch water pipe.

[0072] like Figures 1-6 As shown, the flow meter assembly 4 includes:

[0073] A housing 41 having a scale mark 411 thereon;

[0074] A connecting portion 46 is formed on the housing 41 and is threadedly mounted on the mounting base 1 ;

[0075] A measuring rod 42, with a convex ring portion 44 formed on the lower end and an indicator plate 45 connected to the upper end;

[0076] The spring 43 is sleeved on the measuring rod 42 , and two ends of the spring 43 respectively abut against the connecting portion 46 and the indicator plate 45 .

[0077] A second through hole 36 is defined in the middle of the valve seat 35 and passes through the upper and lower end surfaces of the valve seat 35 . The measuring rod 42 is passed through the second through hole 36 , so that the convex ring portion 44 can be disposed in the water outlet channel 32 .

[0078] When water flows into the water outlet channel 32 , the water flows impact the convex ring portion 44 and pushes the convex ring portion 44 downward, thereby driving the measuring rod 42 to move, and then cooperate with the scale mark 411 on the housing 41 to display the flow.

[0079] Furthermore, a positioning seat 38 is protruding from the valve seat 35 , and the lower end of the spring 43 is sleeved on the outside of the positioning seat 38 , thereby fixing the position of the lower end of the spring 43 .

[0080] As a preferred embodiment, the diameter of the water outlet channel 32 gradually increases from top to bottom. Since the area covered by the convex ring portion 44 is constant, when the water flow pushes the convex ring portion 44 to continuously move, the area that the water flow can pass through in the water outlet channel 32 also gradually increases. This can slow down the water flow while maintaining a stable flow rate, thereby preventing damage to the flow meter assembly 4.

[0081] Furthermore, the housing 41 is made of a transparent material, so that the indicator plate 45 and the scale mark 411 can cooperate to display the reading.

[0082] As another preferred embodiment, a collar 412 is sleeved on the housing 41 , and the collar 412 can indicate the designed flow rate, thereby facilitating comparison with real-time data when reading and facilitating detection of the working status of the flow meter assembly 4 .

[0083] like Figures 1-6 As shown, the sleeve 5 is further included. The sleeve 5 is formed with a first connecting groove 51 and a second connecting groove 52 . The first connecting groove 51 is communicated with the second connecting groove 52 .

[0084] A rack portion 54 is formed in the first connecting groove 51 .

[0085] A rack portion 2 39 is formed on the outside of the valve seat 35, and the rack portion 1 54 matches the rack portion 2 39, so that the sleeve 5 can be sleeved on the outside of the valve seat 35. By rotating the sleeve 5, the valve seat 35 can be driven to rotate, thereby facilitating the control of the screw connection between the valve seat 35 and the mounting seat 1.

[0086] The valve seat 35 is placed into the bottom end of the screw connection groove 15, and the water retaining portion 34 blocks the water diversion port 13.

[0087] or,

[0088] The valve seat 35 is placed in the upper end of the screw connection groove 15, and the water retaining portion 34 no longer blocks the water diversion port 13. The water diversion port 13 is connected with the water inlet 33, which facilitates the water flow in the water diversion pipe to enter the water outlet channel 32.

[0089] An escape hole 53 is defined in the first connecting groove 51 , and the escape hole 53 is used for allowing the housing 41 to extend out.

[0090] The mounting seat 1 is protruded with a protrusion 16, which can be placed in the second connecting groove 52, so that the sleeve 5 can be simultaneously mounted on the outside of the mounting seat 1 and the valve core 3, thereby facilitating accurate connection between the valve seat 35 and the mounting seat 1.

[0091] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
