Description

Technical Field

[0001] The invention relates to the technical field of water meter detection, in particular to a water meter silicone sealing ring sealing detection device. Background Art

[0002] The silicone sealing ring inside the water meter is one of the key components to ensure the normal operation of the water meter and prevent leakage. After mass production, a certain number of water meters need to be randomly selected for water flow testing. The purpose is to detect the sealing performance of the internal silicone sealing ring and determine whether the water meter meets the quality requirements.

[0003] The existing test is mainly carried out in the following way: by installing the water meter on the water pipe, letting water in at one end of the water pipe and out at the other end, observing whether there is water seepage between the water meter housing and the cover plate, and judging the sealing of the water meter sealing ring; however, there are the following defects when testing the water meter to be tested:

[0004] 1. When testing the sealing of the silicone sealing ring of the water meter, multiple screws and bolts are usually used to connect the water meter and the water pipe together. When testing multiple water meters, multiple water meters need to be connected to the water pipe in turn. At this time, it is necessary to continuously use a wrench to tighten the screws and bolts. Manually tightening the bolts takes a long time, which will increase the installation and disassembly time of the water meter, making the detection process complicated and lengthy. At the same time, frequent twisting may cause thread wear or damage, increasing the testing cost.

[0005] 2. When testing the water flow of a water meter, the water meter is usually tested for the rated test time. In order to improve the accuracy of the test results, the internal water flow size is usually dynamically simulated to determine the sealing performance of the internal silicone sealing ring. However, the test results usually lack comparison, and the specific test process still needs to be improved.

[0006] Therefore, the present invention proposes a water meter silicone seal ring sealing detection device to make up for and improve the deficiencies of the prior art. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention will be further described below in conjunction with the embodiments.

[0035] See also Figure 1 and Figure 3A water meter silicone sealing ring sealing detection device of the present embodiment includes a test bench 1, three groups of left-right sliding grooves 2 are opened on the top of the test bench 1, and a first support rod 3 and a second support rod 15 are slidably connected to each other in each slide groove 2, a first connecting pipe 5 is fixedly connected to the top of each first support rod 3, and a water meter body 4 is fixedly connected to the top of each second support rod 15. The ends of two adjacent first connecting pipes 5 close to each other are each provided with a first flange 6, and a connecting mechanism 7 is provided on the outside of each first flange 6. A docking mechanism 9 for aligning multiple water meter bodies 4 and first connecting pipes 5 is provided at the bottom of the test bench 1. A circulation mechanism 10 is also provided at the bottom of the test bench 1, and a telescopic component 77 is provided between the first flange 6 and the first connecting pipe 5.

[0036] See also Figure 1 , Figure 7 and Fig.10 The docking mechanism 9 includes a fixing plate 92 fixedly connected to the bottom of the leftmost first support rod 3 , a second hydraulic rod 91 is fixedly connected to the lower surface of the test bench 1 , and a telescopic end of the second hydraulic rod 91 is fixedly connected to the fixing plate 92 .

[0037] A steel cable 93 is fixedly connected to the bottom of each second support rod 15 symmetrically. One end of each steel cable 93 away from the bottom of the second support rod 15 is fixedly connected to the bottom of the corresponding first support rod 3 .

[0038] During specific operation, when connecting the water meter body 4 and the first connecting tube 5, it is necessary to move the first support rod 3 for fixing the first connecting tube 5 and the second support rod 15 for fixing the water meter body 4 to the right along the slide groove 2, so that multiple first connecting tubes 5 and the water meter body 4 are docked together. At this time, the second hydraulic rod 91 is retracted to control the fixed plate 92 at the telescopic end to drive the leftmost first support rod 3 to move to the right, and the first connecting tube 5 at the top of the first support rod 3 pushes the water meter body 4 on the right to move to the right in turn, thereby docking multiple first connecting tubes 5 and multiple water meter bodies 4 together.

[0039] After completing the sealing test, the tested water meter body 4 needs to be disassembled. After the connection mechanism 7 is released, the telescopic end of the second hydraulic rod 91 needs to be moved outward. The second hydraulic rod 91 drives the leftmost first support rod 3 to move to the left through the fixed plate 92. The leftmost first support rod 3 pulls the second support rod 15 to move to the left through the steel cable 93. The first support rod 3 and the second support rod 15 are pulled away from each other in turn by multiple steel cables 93. The first support rod 3 and the second support rod 15 are pulled away from each other in turn. The first support rod 3 that moves away from each other drives the first connecting pipe 5 and the water meter body 4 to disengage from each other, thereby realizing the separation of the first connecting pipe 5 and the water meter body 4.

[0040] See also Figure 5The connecting mechanism 7 includes a sliding sleeve 71 which is slidably sleeved on the outside of the first connecting tube 5. The outside of the sliding sleeve 71 is fixedly connected with a plurality of push rods 72 in a ring shape. Each push rod 72 is rotatably connected with a lever 73 at one end away from the sliding sleeve 71. The middle part of each lever 73 is rotatably connected to the first flange 6 through a hinge seat. The end of the lever 73 away from the push rod 72 is fixedly connected with an extrusion block 74.

[0041] See also Figure 5 and Figure 8 The connecting mechanism 7 also includes a connecting rod 75 fixedly connected to the outside of the sliding sleeve 71, and a ring 76 is fixedly connected to one end of the connecting rod 75 away from the sliding sleeve 71. A plurality of groups of synchronous moving components 8 are arranged on the upper surface of the test bench 1 directly below the ring 76.

[0042] During specific operation, when it is necessary to fix the first connecting pipe 5 and the water meter body 4 together through the connecting mechanism 7, the telescopic end of the first hydraulic rod 83 drives the support plate 82 to move upward, and the support plate 82 drives the triangular block 81 to move upward synchronously. The inclined surface of the upward moving triangular block 81 contacts the circular ring 76, and the inclined surface of the triangular block 81 pushes the circular ring 76 to move away from the water meter body 4. At this time, the circular ring 76 drives the lever 73 to deflect through the push rod 72, and the extrusion block 74 at one end of the lever 73 away from the push rod 72 squeezes the two end interfaces of the water meter body 4 toward the surface of the first flange 6, thereby fixing the water meter body 4 and the first connecting pipe 5 together.

[0043] When disconnecting the first connecting pipe 5 and the water meter body 4 that are fixed together, first move the telescopic end of the first hydraulic rod 83 downward to drive the support plate 82 to move, and the support plate 82 drives the triangular block 81 to move downward synchronously, and the inclined surface of the downwardly moving triangular block 81 is separated from the contact with the circular ring 76, and then the circular ring 76 is manually moved toward the water meter body 4, and the circular ring 76 drives the lever 73 to rotate through the push rod 72, and the lever 73 drives the extrusion block 74 to separate from the interfaces at both ends of the water meter body 4.

[0044] See also Figure 6 and Figure 8 Each group of synchronous moving components 8 includes a first hydraulic rod 83 fixedly connected to the lower surface of the test bench 1. The telescopic end of the first hydraulic rod 83 penetrates the test bench 1 and extends to the top of the test bench 1. The telescopic end of the first hydraulic rod 83 is fixedly connected to a support plate 82. A plurality of triangular blocks 81 are fixedly connected to the side of the support plate 82. Each triangular block 81 is located directly below the circular ring 76, and the triangular blocks 81 correspond to the circular ring 76 one by one.

[0045] See also Fig. 9The telescopic assembly 77 includes an inner sleeve 771 fixedly connected to the inner wall of the first flange 6, the inner sleeve 771 is slidably connected to the inner wall of the first connecting pipe 5 at one end away from the first flange 6, and a first bellows 772 is fixedly connected to the side of the first flange 6 close to the first connecting pipe 5, and the first bellows 772 is fixedly connected to the outside of the first connecting pipe 5 at one end away from the first flange 6.

[0046] During specific operation, first, when the first flange 6 is docked with the water meter body 4, there is a certain gap between the first flange 6 and the water meter body 4. When the interface of the first flange 6 and the water meter body 4 is fixed together through the connecting mechanism 7, the first flange 6 will move slightly toward the interface of the water meter body 4. At this time, the first flange 6 moves together with the inner sleeve 771 toward the interface close to the water meter body 4, and pulls the first bellows 772 to extend during the movement.

[0047] See also Figure 4 The test bench 1 is symmetrically provided with second connecting pipes 13, each second connecting pipe 13 is provided with a second flange 14 at one end close to the water meter body 4, a telescopic component 77 is also provided between the second flange 14 and the second connecting pipe 13, and a connecting mechanism 7 is also provided outside the second flange 14.

[0048] See also Figure 3 and Figure 4 The second bellows 11 is fixedly connected to one end of the left second connecting pipe 13 away from the second flange 14 , and the valve 12 is fixedly connected to one end of the right second connecting pipe 13 away from the second flange 14 .

[0049] See also Figure 2 and Figure 3 The circulation mechanism 10 includes a water tank 102 fixedly connected to the bottom of the test bench 1. The right side of the water tank 102 is connected to the water inlet end of the booster pump 103 through a hose, and the water outlet end of the booster pump 103 is connected to the three second connecting pipes 13 on the right side through a four-way pipe 101. The left side of the water tank 102 is connected to the second connecting pipes 13 on the left side through the four-way pipe 101.

[0050] In specific operation, after the installation and fixation of the water meter body 4 is completed, the water flow in the water tank 102 is transported to the right four-way pipe 101 through the pressure pump 103, and the pressurized water flow is respectively transported to three groups of second connecting pipes 13 through the four-way pipe 101, and then the water flows through the water meter body 4 and the first connecting pipe 5, wherein the water meter bodies 4 used for testing are grouped into three, and a group of water meter bodies 4 is respectively arranged on the top of each chute 2, and the water flow through the water meter body 4 flows to the left second connecting pipe 13, and finally flows back to the water tank 102 from the left second connecting pipe 13. During the test, the water flow of the water meter body 4 in each group can be controlled by closing the valve 12 in sequence after a specified time interval, in order to increase the water flow in each subsequent group of water meter bodies 4.

[0051] The overall working process:

[0052] After a batch of water meters is produced, 9 water meter bodies 4 are randomly selected as test pieces and divided into three groups to test the sealing performance of the silicone sealing ring inside the water meter;

[0053] Before the test, the water meter body 4 and the first connecting pipe 5 and the second connecting pipe 13 are connected together in sequence. After the connection is completed, the connection mechanism 7 is driven by the rising triangular block 81 to fix the water meter body 4 and the first connecting pipe 5 and the second connecting pipe 13 together. During the fixing process, the first flange 6 and the second flange 14 are slightly moved toward the interface of the water meter body 4 through the telescopic assembly 77, so that the connection between the water meter body 4 and the first connecting pipe 5 and the second connecting pipe 13 is tighter.

[0054] After the connection is completed, the water flow is continuously circulated in the water meter body 4 through the circulation mechanism 10. After a certain period of circulation, observe whether there is water seepage or dripping outside the water meter body 4 in each group. If any one of the three groups of water meter bodies 4 leaks, it can be determined that the batch of water meter bodies 4 has failed the inspection. If no leakage occurs, close the valve 12 of one group of water meter bodies 4 at random (at this time, after closing the valve 12, the liquid circulation pressure inside the water meter bodies 4 of the other two groups has increased), and the remaining two groups are tested and continue to flow water for a certain period of time; if the two groups are leaking, If any one of the water meter bodies 4 in a group leaks, the water meter bodies 4 of this batch can be judged as unqualified. If no leakage occurs, close the valve 12 of one group of water meter bodies 4 at random (at this time, after closing the valve 12, the liquid flow pressure inside the water meter bodies 4 of the remaining group continues to increase), and continue to pass water for a certain period of time; observe whether any water meter body 4 in the group leaks. If so, record the number and calculate the defective rate. By comparing with the allowed defective rate, judge whether the sealing of the silicone sealing rings of this batch of water meters is qualified. If not, directly judge it as qualified.

[0055] After the test is completed, the second hydraulic rod 91 drives the leftmost first support rod 3 to move to the left through the fixed plate 92, and the leftmost first support rod 3 pulls the second support rod 15 to move to the left through the steel cable 93. The first support rod 3 and the second support rod 15 are pulled away from each other in turn by multiple steel cables 93. The first support rod 3 moving away from each other drives the first connecting pipe 5 and the water meter body 4 to break contact with each other, thereby realizing the separation of the first connecting pipe 5 and the water meter body 4.
