Background

The water supply equipment is a water supply device which is automatically started and stopped and outputs a certain flow and a certain lift in unit time. In recent years, with rapid development of economy, tall buildings such as bamboo shoots in the spring after rain stand upright in front of people. However, the municipal pipe network can only reach about 0.2MPa, so the water pressure and quality of water for users in high-rise buildings always troubles designers of water supply companies, and the water supply problem of water towers is fundamentally solved by non-negative pressure water supply equipment along with the development of secondary water supply pressurization technology.

The water supply equipment without negative pressure is generally referred to as non-negative pressure variable frequency water supply equipment, also called variable frequency non-negative pressure water supply equipment. The traditional water supply mode can not leave the reservoir, and water in the reservoir is generally supplied by a tap water pipe, so that pressurized water enters the water pool and becomes zero, and a large amount of energy is wasted. The non-negative pressure water supply equipment is ideal energy-saving water supply equipment, is secondary water supply equipment which can be directly connected with a tap water pipe network and does not generate any side effect on the tap water pipe network, directly folds and supplies water on the basis of municipal pipe network pressure, saves energy, and has the advantages of full sealing, no pollution, small occupied area, quick installation, reliable operation, convenient maintenance and the like.

When water supply equipment is used in operation or is maintained in an off-line state, the corresponding pipeline needs to be completely blocked under certain conditions, but when the pipeline is blocked by the existing blocking device, the blocking effect is poor, and the leakage and even the loosening are easy to occur.
