Description

Technical Field

[0001] This utility model relates to the field of water meter testing technology, and in particular to a water meter sealing test device. Background Technology

[0002] Water meter sealing testing is a crucial technical step in ensuring the accuracy and safety of water meter measurement. Its core objective is to prevent water waste, measurement errors, and economic losses for users due to leaks. Traditional testing methods mainly include pneumatic and hydrostatic methods: the pneumatic method monitors the pressure drop by injecting compressed air, which is characterized by no water residue and high efficiency, but has limited sensitivity to minor leaks; the hydrostatic method visually observes leaks by injecting water and pressurizing it, which is intuitive but requires drainage and drying, affecting production cycle.

[0003] Currently, the core modules of the water meter sealing test device include a clamping mechanism, pressure supply, leakage detection, and an automated control system; the clamping mechanism is used to fix the water meter and ensure that the water meter is in a stable position during the test.

[0004] However, existing clamping mechanisms typically clamp the water meter from both sides. During the clamping process, it is inconvenient to position the water meter. The water meter is prone to tilting, causing the end faces of the pipes at both ends of the water meter to be in a corner-to-corner state with the seal, affecting the sealing effect. Moreover, the water meter is at risk of falling, making it difficult to meet the usage requirements. Utility Model Content

A fixing seat is fixedly mounted on one end of the base plate, and a clamping seat is slidably mounted on the other end of the base plate. Sealing gaskets are fixedly mounted on the fixing seat and the clamping seat. The end faces of the pipes at both ends of the water meter abut against the corresponding sealing gaskets, and a guide cylinder is detachably mounted on the fixing seat. A connecting cylinder is detachably mounted on the clamping seat. A guide sleeve is elastically slidably mounted on the outer wall of the connecting cylinder. The guide cylinder and the guide sleeve extend into the pipes at both ends of the water meter. A positioning ring is fixedly mounted on the outer wall of one end of both the guide cylinder and the guide sleeve. The outer walls of the two sets of positioning rings abut against the inner walls of the pipes at both ends of the water meter.

[0008] To ensure reliable sliding of the guide sleeve, preferably, a retaining ring is fixedly provided at one end of the connecting cylinder, the outer wall of the retaining ring abuts against the inner wall of the guide sleeve, and a baffle is fixedly provided at the other end of the guide sleeve.

[0028] Example:

[0029] Reference Figures 1-4A water meter sealing performance testing device includes a testing box 1, which is equipped with a control system for automatically executing clamping, pressurizing, holding, and depressurizing processes to improve testing efficiency and accuracy. The control system is existing technology. The device also includes a base plate 101 fixedly mounted on the top of the testing box 1. A protective cover 102 is fixedly mounted on the top of the testing box 1, with the base plate 101 located inside the protective cover 102. A box cover 103 is mounted on top of the protective cover 102. One end of the box cover 103 is rotatably connected to the protective cover 102 via a hinge, and the other end is secured by a buckle, facilitating the opening and closing of the box cover 103. Furthermore, both the protective cover 102 and the box cover 103 are made of transparent acrylic, facilitating observation of the testing conditions inside the protective cover 102. During use, the protective cover 102 is fixedly installed on the testing box 1, and the box cover 103 is installed on top of the protective cover 102. This effectively reduces the risk of water meter components bursting and splashing, thus improving safety. A fixing seat 2 is fixedly installed at one end of the base plate 101, and a clamping seat 3 is slidably installed at the other end of the base plate 101. Sealing gaskets 6 are fixedly installed on the fixing seat 2 and the clamping seat 3. When the clamping seat 3 slides towards the fixing seat 2, the water meter pipes at both ends... The end faces abut against the corresponding sealing gaskets 6 to seal both ends of the water meter. A guide cylinder 4 is detachably installed on the fixed base 2. A connecting cylinder 5 is detachably installed on the clamping base 3. A guide sleeve 503 elastically slides on the outer wall of the connecting cylinder 5. The guide sleeve 503 has the same outer dimensions as the guide cylinder 4. The guide cylinder 4 and guide sleeve 503 extend into the pipes at both ends of the water meter. A positioning ring 402 is fixedly installed on the outer wall of one end of both the guide cylinder 4 and the guide sleeve 503. The positioning ring 402 is made of rubber, nylon, aluminum, or polyurethane. Here, we prefer polyurethane with a certain degree of hardness. The two sets of positioning rings... The outer wall of positioning ring 402 abuts against the inner walls of the pipes at both ends of the water meter. In use, one end of the water meter is fitted onto the guide sleeve 503, and then the guide sleeve 503 is pushed towards the clamping seat 3, so that the other end of the water meter can be fitted onto the guide cylinder 4. At this time, the outer wall of positioning ring 402 abuts against the inner walls of the pipes at both ends of the water meter. Since the guide sleeve 503 slides elastically on the connecting cylinder 5, the water meter can be restricted on the guide cylinder 4 and the guide sleeve 503 under the action of elasticity, thereby positioning the water meter. Then the clamping seat 3 slides towards the fixed seat 2 to clamp the water meter, which can reduce the occurrence of water meter tilting and improve the detection effect.

[0030] In use, by setting a guide cylinder 4 on the fixed base 2 and elastically setting a guide sleeve 503 on the clamping base 3, and fixing a positioning ring 402 on both the guide cylinder 4 and the guide sleeve 503, the water meter can be restricted on the guide cylinder 4 and the guide sleeve 503 to achieve positioning of the water meter. Then the clamping base 3 slides towards the fixed base 2 to clamp the water meter, which can reduce the occurrence of water meter tilting and improve the detection effect.

[0031] Reference Figure 4 A retaining ring 501 is fixedly installed at one end of the connecting cylinder 5, with the outer wall of the retaining ring 501 abutting against the inner wall of the guide sleeve 503. A baffle 504 is fixedly installed at the other end of the guide sleeve 503, and the baffle 504 is sleeved on the connecting cylinder 5. A spring is sleeved on the connecting cylinder 5, with both ends of the spring abutting against the baffle 504 and the clamping seat 3, respectively. In use, by fixing the retaining ring 501 on the connecting cylinder 5 and the baffle 504 on the guide sleeve 503, the guide sleeve 503 can be reliably slid on the connecting cylinder 5. Moreover, the spring sleeved on the connecting cylinder 5 gives the guide sleeve 503 an elastic sliding effect. Under the action of the spring, the water meter is briefly clamped and positioned, improving the usage effect.

[0032] Reference Figure 2 A mounting plate is fixedly installed at the other end of the base plate 101, and a cylinder is fixedly installed on the mounting plate. The output end of the cylinder is fixedly connected to the clamping seat 3 to facilitate driving the clamping seat 3 to perform clamping. A guide rod is fixedly installed on the clamping seat 3. Here, we symmetrically arrange two sets of guide rods. The end of the guide rod away from the clamping seat 3 is slidably connected to the mounting plate, and the axis of the guide rod is parallel to the sliding direction of the clamping seat 3. This can ensure that the clamping seat 3 slides reliably, reduce the occurrence of skew, and improve the use effect.

[0033] Reference Figure 4 A connecting plate 303 is fixedly installed at the bottom of the clamping base 3, and a motor 8 is fixedly installed on the connecting plate 303. A rotating block 801 is fixedly installed at the output end of the motor 8. A through hole is opened on the rotating block 801, and a rope 802 is fixedly installed in the through hole. A rubber ball for striking the outer wall of the water meter is fixedly installed at one end of the rope 802. Here, a bolt is threadedly connected to the rotating block 801. The axis of the bolt is perpendicular to the axis of the through hole, and the end of the bolt extending into the rotating block 801 abuts against the rope 802. This not only fixes the rope 802, but also facilitates the adjustment of the distance between the rubber ball and the rotating block 801, improving the usage effect. When in use, by starting the motor 8 to rotate the rotating block 801, the rubber ball can be swung up and strike the outer wall of the water meter, causing the water meter to produce a certain vibration effect, simulating the effect of pipeline vibration on the water meter's sealing performance, and improving the detection accuracy.

[0034] Reference Figures 1-3An air inlet pipe 104 and an air outlet pipe 105, each equipped with a valve, are fixedly installed on the testing box 1. The pressure supply unit is connected to the air inlet pipe 104 to facilitate the introduction of pressurized gas into the air inlet pipe 104. A first connecting hole 201 is provided on the fixed base 2. A hollow first screw 401 is fixedly installed at the other end of the guide cylinder 4. The first screw 401 is threadedly connected to one end of the first connecting hole 201, and a connecting pipe 202 is threadedly connected to the other end of the first connecting hole 201. The connecting pipe 202 is connected to the air inlet pipe 104. In order to facilitate the detection of the pressure of the gas introduced into the water meter, a pressure gauge 7 for detecting the pressure inside the water meter is fixedly installed on the connecting pipe 202. In use, gas with a certain pressure is introduced into the connecting pipe 202 through the air inlet pipe 104. The gas enters the water meter through the first connecting hole 201, the first screw 401, and the guide cylinder 4, realizing the inflation of the water meter, which facilitates subsequent sealing tests.

[0035] Reference Figure 2 and Figure 4 A second connecting hole 301 is provided on the clamping seat 3. A hollow second screw 502 is fixedly provided at the other end of the connecting cylinder 5. The second screw 502 is threadedly connected to the second connecting hole 301. A connector that communicates with the inside of the second connecting hole 301 is threadedly connected to the clamping seat 3. The connecting threads of the first screw 401, the connecting pipe 202, the second screw 502 and the connector are all pipe threads with sealing effect. In addition, sealant can be applied to the threads or Teflon tape can be wrapped to improve the sealing effect. A flexible hose 302 is provided on the clamping seat (3). The two ends of the flexible hose 302 are respectively connected to the air outlet. Pipe 105 and connector are connected. During use, when gas is introduced into the water meter through air inlet pipe 104, the gas passes through connecting cylinder 5, second screw 502 and hose 302 and is discharged from air outlet pipe 105, indicating that the water meter is unobstructed. Then, close the valve on air outlet pipe 105 and continue to introduce gas into the water meter through air inlet pipe 104. When the value of pressure gauge 7 reaches the set value, close the valve of air inlet pipe 104. After a period of time, observe whether the value of pressure gauge 7 changes. When the value remains almost unchanged, it indicates that the water meter is well sealed. Conversely, when the value drops beyond the set value, it indicates that the water meter is not sealed properly.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
