Open and close underground pipe sub-catchment and its control method

Abstract

The invention discloses an open-and-close underground pipe sub-collector and its control method. They are respectively connected to one end of each water distribution branch pipe in sealing connection, and the other end of each water distribution branch pipe is respectively connected to one end of the corresponding user, and the other end of the user is respectively connected to the corresponding water collection branch pipe in sealing communication, and each water collection branch pipe is sealed to the water collection main pipe respectively. Connected; a set of mechanical self-sealing device is installed between the water inlet of the water distribution branch pipe connected to the same user and the water outlet of the water collection branch pipe; the mechanical self-sealing device includes water distribution side sealing components, water collection side sealing components and limiting Position parts, the water-splitting side plugging assembly and the water-collecting side plugging assembly are screwed together. The sub-catchment can realize the mechanical automatic sealing of the leaking pipeline. When the leakage fault is eliminated, the blockage can be unblocked again, so that the whole sub-catchment can be put into normal use again, which can significantly reduce the loss caused by the leakage of the pipeline. .

Description

technical field [0001] The invention relates to the technical field of sub-water collectors, in particular to an open-and-close underground pipe sub-collector that can automatically block corresponding pipes in a leakage state and a control method thereof. Background technique [0002] The sub-collector refers to the device used to connect the heating main water supply pipe and return pipe in the floor heating system. It is divided into two parts: water separator and water collector. The water separator is a water distribution device used to connect the water supply pipes of various heating pipes in the water system. The water collector is a water collection device used to connect the return pipes of various heating pipes in the water system. The sub-collector is composed of a water-distributing main pipe and a water-collecting main pipe. The water-dividing main pipe is connected to the water supply pipe of the pipe network system. Its main function is to distribute the ho...

Problems solved by technology

However, the structure of this type of system is relatively complex and prone to failure. For example, once the sensor or alarm device in the system fails, the maintenance personnel must not immediately seal the leakage side in time, which will eventually cause greater economic losses.
