Underground pipeline pressure measuring device for urban water supply

Abstract

The invention discloses an underground pipeline pressure measuring device for urban water supply. The underground pipeline pressure measuring device for urban water supply comprises a main transmission rod, a first expanding and supporting assembly and a second expanding and supporting assembly are connected to the main transmission rod, the first expanding and supporting assembly and the second expanding and supporting assembly are oppositely arranged, an air inlet nozzle and a pressure sensor are arranged between the first expanding and supporting assembly and the second expanding and supporting assembly, the air inlet nozzle is fixedly connected to the main transmission rod, an air passing channel is formed in the interior of the main transmission rod, one end of the air passing channelcommunicates with the air inlet nozzle, the other end of the air passing channel communicates with an installation end fixedly connected to the outer side of the main transmission rod, and the installation end is located on the outer side of the first expanding and supporting assembly and the outer side of the second expanding and supporting assembly. According to the underground pipeline pressure measuring device for urban water supply, the convenience of pipeline pressure measuring operation can be improved, the specification of a water supply pipeline does not need to be considered, and the use universality of pipeline pressure measuring is effectively improved.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to an underground pipeline pressure measuring device for urban water supply. Background technique [0002] The water supply system is used to ensure the normal supply of domestic water, industrial water and other water in the city, and is the life of a modern city. For a long time, the leakage rate of the underground water supply pipe network in my country's cities has been very high. A large amount of water leaks through the underground pipe network, causing a huge waste of water resources; "Secondary pollution" and so on all affect the daily life of the people; the leakage of underground water supply pipes will take away a large amount of sediment, forming a large number of subsidence, which constitutes a large number of engineering hidden dangers. It can be seen that the leakage of underground water supply pipelines has caused a large amount of economic losses, and has brough...

Problems solved by technology

In order to ensure that the specifications of the water supply pipeline are qualified, it is necessary to measure the pressure resistance of the water supply pipeline. However, the existing pipeline pressure measurement devices all need to move the water supply pipeline. Due to the large volume of the water supply pipeline, it is extremely inconvenient to move and increase. On the other hand, due to the different water supply volumes in different regions, the inner diameter specifications of water supply pipes are also different, and the existing pressure measuring devices can only detect one or two commonly used water supply pipe specifications , which is widely used, and it is difficult to meet the needs of pipeline pressure measurement.
