Three choices of fire truck hydrant joint

When manufacturers design the water truck water inlet system, mainly composed of three types: centrifugal self-priming pump water, artesian water and fire hydrant water Guankou. One of the preferred way of fire hydrant water intake is the most efficient way, but also many customers or turn on the water way. 
Advantages fire hydrant water system is that the water fast, water fast, easy to carry fire-fighting water bag, waterproof work stroke length and so on. Hydrants choose to become a primary consideration many customers choose to work today, Xiao Bian will take issues of concern into the technical department, we provide the most comprehensive solution. 
Currently on the market common specifications for the fire hydrant outlet 50, to common national standard fire hydrant fittings and hoses. Truck fire hydrant sprinkler outlet is divided into three types: GB type, ball valve type and valve type. 
GB type: GB manufacturing standards, removable and exchangeable male end, employ pressure valve closed design. Cons: Too much pressure causes damage to the platen closure device, life in general, but lower replacement costs. 
Ball type: a combination of the most expensive fire hydrant. Mainly valve control switch 50, connected by a 120mm flange hydrant fittings, high replacement costs, but durable. Disadvantages: cost is too high. 
Valve type: the most practical hydrant connector. Using a tubular valve control switch, from the valves, fittings and elbows composition, easy to replace, durable. 
Technology Chief Engineer Mr.Wang said that the current domestic water truck fire hydrant connectors are used in a mechanical, external connector design. We are to proceed with electrical fittings and hydrants within button suction joint assembly of the R & D and production work, fire joint way in the future, we will be able to choose more and more humane. Currently, we have German engineers VDI Academy made contact, is preparing to introduce a latest international order of precision equipment home, mainly used for our own research and development of mechanical parts of the development work.
