Rapid pipeline connection seat for fire fighting

Abstract

The invention discloses a quick connecting seat for fire-fighting pipelines, which comprises an upper connecting pipe seat, and a lower connecting pipe seat arranged under the upper connecting pipe seat and fixed with the upper connecting pipe seat; the upper connecting pipe seat includes an upper pipe body, and is arranged on On the outside of the upper pipe body, the upper-spin pattern inclined upwards, and the upper cover arranged at the lower end of the upper pipe body and integrally formed with the upper pipe body; the lower connection seat includes the lower pipe body, and is arranged outside the lower pipe body and a downward-sloping downward spiral, and a card seat arranged on the upper end of the lower tube body and located inside the upper cover; a housing cavity is provided between the card seat and the upper cover, and the housing cavity is filled with There is a sealing ring for anti-seepage; the fast connection seat for fire-fighting pipes has the advantages of simple structure, high connection reliability and good sealing, and the sealing ring has the advantages of high pressure resistance, spinning resistance and not easy expansion and contraction.

Description

technical field [0001] The invention relates to a quick connecting seat for fire-fighting pipelines. Background technique [0002] In fire extinguishing, in order to save lives and property trapped in the fire scene against time, it is necessary to use the quick-plug suction pipe interface invented for the fire pump. At present, the widely used water suction pipe interface includes a connecting seat and a male joint. The connecting seat and the male joint are connected by insertion. However, in the case of emergency rescue, due to the complexity of the connection of the water pipe, it must not only be fast, but also not be squeezed by high-strength water pressure. Therefore, Firefighters often spend a long time when connecting, thereby delaying the timing of rescue; in addition, the existing water pipe joints are all provided with sealing rings, but during use, once the layer of sealing rings is subjected to high pressure and rotation If the pressure is too low, damage will...

Problems solved by technology

At present, the widely used water suction pipe interface includes a connecting seat and a male joint. The connecting seat and the male joint are connected by insertion. However, in the case of emergency rescue, due to the complexity of the connection of the water pipe, it must not only be fast, but also not be squeezed by high-strength water pressure. Therefore, Firefighters often spend a long time when connecting, thereby delaying the timing of rescue; in addition, the existing water pipe joints are all provided with sealing rings, but during use, once the layer of sealing rings is subjected to high pressure and rotation If the pressure is too high, damage will occur, and the entire device will lose its sealing effect. During use, the water pipe will leak, the sealing performance is not good, and the use is unreliable.

[0003] Therefore, to sum up, the existing fire-fighting pipeline quick connection seat has the advantages of complex structure, low connection reliability and poor sealing, and its sealing ring cannot realize high pressure resistance, spinning resistance, and is easy to expand and contract
