Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rural water supply pipelines, in particular to a water pressure detection device for rural water supply pipelines. Background Art
[0002] At present, the detection of water supply pipelines is usually carried out by connecting the detection end of the water pressure detection device to the water supply pipeline, and then injecting water into the water supply pipeline. The water inside the pipeline is kept at a certain pressure through a pressure source such as a water pump. By observing whether the indication of the water pressure detection device changes over a certain period of time, the sealing performance and pressure resistance of the pipeline are judged.
[0003] The commonly used sizes of rural water supply pipes vary depending on the actual situation. Generally speaking, the diameter of rural water supply pipes is usually determined according to the actual situation of the village and the water supply demand. The diameter of the pipe ranges from 50 mm to 200 mm, but the specific size needs to be reasonably selected based on the actual situation.
[0004] During the detection process, the water pressure detection device needs to be connected to the pipeline before detection. The ports of existing water pressure detection devices are usually connected to the pipeline by threads or flanges. Since the joints of the water pressure detection device can only adapt to pipeline interfaces with matching diameters, when the sizes of pipelines at different detection points are different, the port diameters are inconsistent, which will cause the detection device to be unable to connect to the pipeline, thereby making it impossible to detect the water pressure. Utility Model Content
[0005] The embodiment of the utility model provides a water pressure detection device for a rural water supply pipeline to solve the above-mentioned technical problems.
[0006] The embodiment of the utility model adopts the following technical scheme: it includes a main body for testing the sealing performance of the pipeline to be tested, a fixing piece is connected to the outer wall of the main body, the fixing piece is used to fix the relative position between the main body and the pipeline to be tested, and a flexible connector is provided at the input end of the main body, the flexible connector is in a cone shape, and the diameter of the cone-shaped flexible connector gradually decreases from the direction close to the main body to the direction away from the main body, and a water flow channel for connecting the pipeline to be tested and the main body is opened at the center of the flexible connector.
[0007] Furthermore, the outer wall of the cone-shaped flexible connector is a smooth curved structure.
[0008] Furthermore, the outer wall of the cone-shaped flexible connector is provided with a plurality of annular abutment portions, and the diameters of the plurality of annular abutment portions gradually decrease from the direction close to the body to the direction away from the body.
[0009] Furthermore, a plurality of concave annular grooves are provided on the outer wall of the cone-shaped flexible connector and deepen along the axial direction of the flexible connector, and the diameters of the plurality of concave annular grooves gradually decrease from the direction close to the body to the direction away from the body.
[0010] Furthermore, an anti-slip groove is provided on the outer wall of the concave annular groove.
[0011] Furthermore, the fixing member includes a plurality of tie strips connected to the outer wall of the main body.
[0012] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:
[0013] In the utility model, the flexible connector is inserted into the pipe to be detected. Since the flexible connector is in a cone shape, the outer wall of the flexible connector can be set as a smooth curved surface structure or has multiple annular interference parts or multiple concave annular grooves deepened along the axial direction of the flexible connector, etc., thereby further improving the performance of the flexible connector in adapting to pipes to be detected of different sizes. When facing pipes to be detected of different sizes, the pipe to be detected can be inserted to seal and fit them, and then the main body and the pipe to be detected are relatively fixed by a fixing piece.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0027] like Figure 1 The water supply pipeline water pressure detection device shown in the figure comprises a body 2 with a water pressure gauge 12. The input end of the body 2 has a connector connected to the external pipeline 1 to be detected. The connector on the body 2 is usually a Figure 1 The flange 13 shown in the figure is sealedly connected to the pipeline 1 to be detected. Of course, the connector can also be connected to the pipeline 1 to be detected by a threaded connection (the threaded connection method is not shown in the figure). In the specific detection process, the body 2 is first sealedly connected to the output end of the pipeline 1 to be detected through the connector, and the input end (such as the input end) of the pipeline 1 to be detected is supplied by an external water supply device (not shown in the figure). Figure 1 Water is injected in the direction of the arrow A1 in the middle) and the water pressure inside the pipeline 1 to be detected is maintained at a certain value. The water pressure inside the pipeline 1 to be detected can be displayed by the indication of the water pressure gauge 12 on the main body 2. When the indication on the water pressure gauge 12 does not decrease within a certain period of time, it proves that the pipeline 1 to be detected is in a sealed state. When the indication on the water pressure gauge 12 decreases within a certain period of time, it indicates that there is a leak in the pipeline 1 to be detected. The above are all prior arts of the present invention and will not be elaborated on here.
[0028] From the above description, it can be seen that the connector on the existing body 2 and the output end of the pipeline 1 to be detected are connected by threaded connection or flange connection, which are only suitable for pipeline sizes matching the connector, and cannot perform water pressure detection on water supply pipelines of different sizes. Here, the utility model proposes a novel rural water supply pipeline water pressure detection device, which can make the water pressure measurement device suitable for water pressure detection of pipelines 1 to be detected of different sizes.
[0029] The utility model provides a rural water supply pipeline water pressure detection device, including a body 2 for detecting the sealing performance of a pipeline to be detected 1, a fixing piece is connected to the outer wall of the body 2, and the fixing piece is used to fix the relative position between the body 2 and the pipeline to be detected 1, and a flexible connector 3 is arranged at the input end of the body 2, and the flexible connector 3 is made of flexible materials such as rubber, and the flexible connector 3 is in a cone shape, and the diameter of the cone-shaped flexible connector 3 gradually decreases from the direction close to the body 2 to the direction away from the body 2, and a water flow channel 4 for connecting the pipeline to be detected 1 and the body 2 is opened at the center of the flexible connector 3, and the flexible connector 3 is inserted into the pipeline to be detected 1, because the flexible connector 3 is The cone shape can be inserted into the pipe to be detected 1 to seal it when facing pipes 1 to be detected of different sizes. In the sealed state, water will not leak out to avoid affecting the internal water pressure of the pipe to be detected 1. The main body 2 and the pipe to be detected 1 are relatively fixed by the fixing parts, so that the flexible connector 3 will not be flushed out of the pipe to be detected 1 when the pipe to be detected 1 is filled with water. Water is injected into the pipe to be detected 1, and the injected water enters the main body 2 through the water flow channel 4. The water inside the pipe to be detected 1 is kept at a certain pressure through a pressure source such as a water pump. The water pressure detection main body 2 detects the internal water pressure, so that the water pressure detection device can adapt to the detection of water supply pipes of different sizes.
[0030] Preferably, Figure 2-3 As shown, the outer wall of the cone-shaped flexible connector 3 is a smooth curved structure. The flexible connector 3 is inserted into the pipe to be detected 1. Due to the flexible characteristics of the material, the portion inserted into the pipe to be detected forms a parallel fit with the inner wall of the pipe to be detected 1, thereby forming a first sealing area 9 to prevent water from flowing out.
[0031] Preferably, Figure 4-5As shown, the outer wall of the cone-shaped flexible connector 3 is provided with a plurality of annular contact parts 5. The arrangement of the plurality of annular contact parts 5 can make the pipelines 1 to be detected of different sizes conflict with the annular contact parts 5 of different diameters. When the pipeline 1 to be detected squeezes the annular contact part 5, the annular contact part 5 is deformed inwardly, so that the contact between the flexible connector 3 and the pipeline 1 to be detected is tighter, forming a second sealing area 10 to prevent water from flowing out. Because the larger the diameter of the pipeline 1 to be detected, the larger the edge width, the diameter of the plurality of annular contact parts 5 gradually decreases from the direction close to the main body 2 to the direction away from the main body 2, which can adapt to the contact between the pipeline 1 to be detected and the annular contact part 5.
[0032] Preferably, Figure 6-7 As shown, a plurality of concave annular grooves 6 are provided on the outer wall of the cone-shaped flexible connector 3 and deepened along the axial direction of the flexible connector 3. The pipeline 1 to be detected is inserted into the concave annular groove 6, so that the flexible connector 3 and the pipeline 1 to be detected are more stable and fit together. The diameters of the plurality of concave annular grooves 6 gradually decrease from close to the main body 2 to away from the main body 2, so that pipelines 1 to be detected of different sizes can be inserted into concave annular grooves 6 of different diameters.
[0033] Preferably, Figure 8 As shown, an anti-skid groove 7 is provided on the outer wall of the concave annular groove 6. When the pipeline 1 to be detected is inserted into the concave annular groove 6, it is clamped in the anti-skid groove 7 through an external clamp (not shown in the figure), so that the outer wall of the concave annular groove 6 is more closely fitted to the pipeline 1 to be detected to form a third sealing area 11 to prevent water from flowing out.
[0034] Preferably, Figure 3-4 As shown, the fixing member includes a plurality of tie strips 8 connected to the outer wall of the main body 2. The fixing member is not limited to this fixing method. The tie strips 8 are wrapped around the pipeline 1 to be detected, so that the pipeline 1 to be detected and the main body 2 are relatively fixed, thereby preventing the main body 2 from being washed out of the pipeline 1 to be detected by running water due to the loose fixation between the main body 2 and the pipeline 1 to be detected.
