Description

Technical Field

[0001] The utility model relates to the field of pipeline connection structures, in particular to a pipeline connection structure of water supply equipment. Background Art

[0002] Non-negative pressure water supply equipment is also called pipe network superimposed water supply equipment. Non-negative pressure water supply equipment is a pressurized water supply unit, which is directly connected to the municipal water supply network and is connected in series with the municipal pipe network on the basis of the residual pressure of the municipal pipe network to ensure that the municipal pipe network pressure is not less than the set protection pressure. It is a secondary pressurized water supply equipment. When the non-negative pressure water supply equipment is supplying water, it is necessary to connect the pipes together. At present, the pipes are more or less connected by flange connection. Although the flange connection can achieve the purpose of connection, there are still certain problems in use. For example, in order to ensure the sealing of the two flanges when connected, a flange will be installed between the two flanges. There is a single sealing gasket, but with long-term use, the sealing gasket will slowly corrode due to environmental factors, causing the sealing effect to deteriorate over time, leading to water leakage at the flange joint. At the same time, the traditional flange connection lacks a buffer structure. When one section of the pipeline in the pipeline network is damaged and needs to be replaced, the flanges at both ends of the pipeline need to be separated from the flanges on both ends of the pipeline. However, since the position of the pipeline will be fixed after installation, after the flanges are separated, the flange gap between the two pipelines is limited, making it inconvenient to take the damaged pipeline out from between the two pipelines, which in turn makes it inconvenient to replace the damaged pipeline. Utility Model Content

[0003] The utility model aims to provide a pipeline connection structure of water supply equipment, which has the advantages of good sealing effect and convenient replacement.

[0004] The above technical purpose of the utility model is achieved through the following technical scheme: it includes a connecting hose, the interior of the connecting hose is compounded with a conveying hose, both ends of the connecting hose are provided with water supply pipes, both ends of the connecting hose and the opposite side of the two water supply pipes are fixedly sleeved with connecting flanges, a first sealing ring is provided between the two connecting flanges, a fixing seat is symmetrically clamped between the two connecting flanges, and the surface of the connecting flange is sleeved with a sealing strip.

[0005] By adopting the above technical scheme, the utility model compounds a conveying hose inside the connecting hose, and the connecting flanges are fixedly sleeved at both ends of the connecting hose. When the connecting flange on the conveying hose is separated from the connecting flanges on the two water supply pipes, the conveying hose is compressed to drive the connecting flange to separate from the connecting flanges on the water supply pipes, thereby increasing the gap between the two, facilitating the subsequent separation of pipelines and improving practicality. A first sealing ring is installed between the two connecting flanges, and a sealing strip is installed between the fixing seat and the connecting flange, so that the two connecting flanges have double sealing protection, thereby improving the sealing between the two flanges, and are fixed together through two fixing seats between the two connecting flanges without the need for bolts, thereby improving the convenience of installation.

[0006] The utility model is further configured as follows: a first sealing groove used in conjunction with a first sealing ring is provided between the two connecting flanges and on one side of the water supply pipe close to the connecting hose.

[0007] The above technical solution is adopted to facilitate the installation of the first sealing ring.

[0008] The utility model is further configured as follows: the interior of the fixing seat and the surface of the connecting flange are both provided with inner grooves used in conjunction with the sealing strip.

[0009] The adoption of the technical solution facilitates the installation of the sealing strip.

[0010] The utility model is further configured as follows: the material of the connecting hose is EPDM rubber.

[0011] By adopting the above technical solution, the durability of the connecting hose is improved.

[0012] The utility model is further configured as follows: the material of the delivery hose is medical silicone.

[0013] The above technical solution is adopted to prevent the transported water from causing harm to the human body.

[0014] The utility model is further configured as follows: the fixing seat is symmetrically bolted with connecting ears, and a limit bolt is threadedly connected between two connecting ears.

[0015] The above technical solution is adopted to facilitate the installation of the two fixing seats together.

[0016] The utility model is further configured as follows: the material of the connecting flange is stainless steel.

[0017] The above technical solution is adopted to improve the corrosion resistance of the connecting flange.

[0018] The utility model is further configured as follows: the material of the fixing seat is stainless steel.

[0019] By adopting the above technical solution, the corrosion resistance of the fixing seat is improved.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model has a delivery hose compounded inside the connecting hose, and connecting flanges are fixedly sleeved at both ends of the connecting hose. When the connecting flange on the delivery hose is separated from the connecting flanges on the two water supply pipes, the delivery hose is compressed to drive the connecting flange to separate from the connecting flange on the water supply pipe, thereby increasing the gap between the two, facilitating the subsequent separation of the pipes, and improving practicality;

[0022] 2. The utility model installs a first sealing ring between the two connecting flanges, and installs a sealing strip between the fixing seat and the connecting flange, so that the two connecting flanges have double sealing protection, improves the sealing between the two flanges, and fixes the two connecting flanges together through two fixing seats without the use of bolts, thereby improving the convenience of installation.
