(1) hydraulic conditions
Only when the inner wall of the water supply pipeline is not fouled, smooth and smooth can the loss of water head be reduced and the service water head be guaranteed.The soft rubber joint can reduce vibration and noise, and compensate thermal expansion and contraction caused by temperature change.Widely used in various pipe systems.
(2) high sealing performance
Water supply pipe network is pressure pipe network, only good pipeline closure, is the basic guarantee of continuous water supply.In order to prevent the natural shrinkage of rubber soft joints in long-term use and reduce the aging of the fracture, the use of wire mesh for multi-body protection.
(3) construction investment province
The construction cost of water supply pipe network usually accounts for 50% of the construction cost of water supply system.Therefore, how to determine the construction scale of water supply pipe network through technical and economic analysis, and how to rationally select pipe materials and rubber soft joints is the guarantee of reasonable operation of the pipe network.
(4) device control device
Special equipment in the pipe network includes: valves, fire hydrants, ventilation valves, exhaust valves, flushing and drainage valves, pressure reducing valves, flow regulating valves, water hammer eliminators, wellbore maintenance, telescopic devices, dregs, flow and pressure measuring devices, etc.The integrity of these devices is the premise to ensure the smooth operation of the pipe network and avoid pollution.The rubber soft joint is vulcanized and combined with metal flange or parallel joint loose sleeve.
(5) good water quality
It can take hours or even days to deliver water from a water plant to customers through a long pipe.The pipe network is actually a large reactor.The unfinished chemical reaction of the factory water will continue in the pipe network, and the chlorine water will make new contact with the pipe wall, which may produce new reactions.These reactions are biological.Sensory and physical chemistry.The rubber joint is used for hollow rubber products and is used as a flexible joint between metal pipes.Therefore, the inner wall of the tube is required to be corrosion resistant and not to precipitate harmful substances into the water.
