Suction valve role in water supply and exhaust engineering
Suction valve, a device generally used for the isolation of toxic air. Widely used in a variety of vacuum-prone systems, such as fire protection, swimming pool, green sprinkler irrigation, water supply and drainage, docks, power plants, metallurgy, shipbuilding and other fields in the formation of negative pressure system inhaled air protection system in a timely manner When the system is operating or stopped to generate negative pressure or the vacuum is gradually increased, the vacuum breaker can be automatically turned on to destroy the vacuum effect, so as to prevent the pipeline and other equipment from being deflated or denting to protect the safety of the equipment.
As a common water supply and exhaust valve body, in the end intake valve played what role? The main purpose of the suction valve is suitable for industrial media as water pipeline, as a rapid elimination of gas pipeline equipment, in order to improve the efficiency of water transport equipment and protection of the pipeline will not be deformed and rupture, is the pipeline of essential equipment. Valve for the barrel-like valve body, a total of the main internal stainless steel float and plug.
Vacuum suction valve is mainly used to automatically eliminate the vacuum in the water supply pipe to effectively prevent the siphon return, eliminate back-flow pollution. Reflux pollution has a great impact on water quality, even in serious cases, life-threatening. So now the water provisions must be set suction valve. The valve is installed at the pump outlet or water distribution pipeline to a large number of pipes to exclude the accumulation of air in order to enhance the efficiency of water pipes and pumps, and the tube once the negative pressure, the valve can quickly inhale the air, To keep the line due to negative pressure damage.
In short, the suction valve in the system is equivalent to a negative pressure safety valve, the protection system is extremely important, so you can not cancel the system on the suction valve, it can not reduce the number of system suction valve. Now on the market a variety of common suction valve, the functional characteristics will be different, if you need to buy, Xiao Bian proposed to go online to see a variety of suction valve working principle and its role characteristics.
