Description

Technical Field

[0001] The utility model relates to a pipeline connector for a gas pipeline water cut-off valve. Background Art

[0002] A gas pipeline is a pipeline used to transport natural gas and other fuel gases. The sealing of the pipeline needs to be ensured during the transportation of gas. In addition to preventing gas leakage, it is also necessary to prevent water from entering the pipeline. When water enters the pipeline, the mixture of water and gas will make the gas unusable.

[0003] In conventional applications, water may seep into the pipeline due to various factors. The water shutoff valve is a structure that drives the valve body to close by the force of water after water enters. Based on this valve body, how to install the water shutoff valve in the gas pipeline so that the water shutoff valve can play a role of shutting off and sealing when water enters is a problem that needs to be considered in existing pipeline installation.

[0004] Therefore, there is an urgent need for a pipe connector for installing a water cut-off valve in a gas pipeline to solve the problem of assembling the water cut-off valve and the gas pipeline. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a pipeline connector for installing a water cut-off valve in a gas pipeline.

[0006] A pipe connector for a gas pipeline water shut-off valve designed for this purpose includes a main pipe fitting, an installation cavity for installing the water shut-off valve is formed in the main pipe fitting, a first connecting pipe fitting and a second connecting pipe fitting for installing a gas pipeline network are respectively arranged on the left and right sides of the main pipe fitting, the first connecting pipe fitting and the second connecting pipe fitting are both communicated with the installation cavity, and a water storage cavity is arranged on the lower side of the main pipe fitting, and the water storage cavity is communicated with the installation cavity.

[0008] Preferably, the main pipe, the first connecting pipe and the second connecting pipe are of an integrated structure.

[0009] Compared with the prior art, the utility model includes a main pipe fitting, in which a mounting cavity for installing a water shutoff valve is formed, and a first connecting pipe fitting and a second connecting pipe fitting for installing a gas pipe network are respectively provided on the left and right sides of the main pipe fitting, and the first connecting pipe fitting and the second connecting pipe fitting are both interconnected with the mounting cavity, and a water storage cavity is provided on the lower side of the main pipe fitting, and the water storage cavity is interconnected with the mounting cavity. The pipeline connector proposed in the utility model can be connected to the gas pipe network through the first connecting pipe fitting and the second connecting pipe fitting, and the water shutoff valve is installed in the mounting cavity, so as to realize the connection and installation of the left and right gas pipe networks and the assembly of the water shutoff valve, thereby solving the problem of assembling the water shutoff valve and the gas pipeline.

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0014] See also Figure 1-Figure 3 A pipe connector for a gas pipeline water shut-off valve comprises a main pipe member 10, wherein an installation cavity 100 for installing a water shut-off valve 20 is formed in the main pipe member 10, and a first connecting pipe member 110 and a second connecting pipe member 120 for installing a gas pipeline network are respectively arranged on the left and right sides of the main pipe member 10, and the first connecting pipe member 110 and the second connecting pipe member 120 are both communicated with the installation cavity 100, and a water storage cavity 130 is arranged at the lower side of the main pipe member 10, and the water storage cavity 130 is communicated with the installation cavity 100.

[0015] The pipeline connector proposed in the utility model can be connected to the gas pipeline network through the first connecting pipe fitting and the second connecting pipe fitting, and the water shut-off valve is installed in the installation cavity, so as to realize the connection and installation of the left and right gas pipelines and the assembly of the water shut-off valve, thereby solving the problem of assembling the water shut-off valve and the gas pipeline.

[0016] The pipe connector and the water shut-off valve are assembled and used. When water enters the gas pipe network, water will flow into the pipe connector and be stored in the water storage chamber. As the water inflow increases, the water level in the water storage chamber gradually rises. The rising water level can push the float of the water shut-off valve to act as a drive. The upward movement of the float can drive the left and right valve plates to move toward the first connecting pipe fitting and the second connecting pipe fitting, so that the valve plate closes the first connecting pipe fitting or the second connecting pipe fitting to cut off the connection between the gas pipe networks on the left and right sides, thereby preventing the problem of water infiltrating the entire gas pipe network after water inflow.

[0017] See also Figure 1 The main pipe component 10 is provided with an inspection port 140 for communicating with the installation cavity 100 , and the inspection port 140 is provided with an inspection cover.

[0018] In the present invention, the main pipe member 10, the first connecting pipe member 110 and the second connecting pipe member 120 are an integrated structure and can be integrally formed by injection molding.

[0019] In the present invention, the water storage chamber 130 is extended from top to bottom.
