From the application point of view of distribution:how many types of valves in our country?
(1)urban construction valves:
Urban Construction Department with the general use of low-pressure valve,is currently environmentally friendly and energy-saving direction.Environment-friendly plastic valve,balance valve and the middle of the butterfly valve,metal butterfly valve is gradually replacing the low pressure iron gate.Domestic urban construction needs more valves for the balance valve,soft seal gate valve,butterfly valve.
(2)urban heating with the valve:
Urban heat generation system,the need to use a large number of metal seal butterfly valve,horizontal balance valve and direct buried ball valve,because of such valves to solve the pipeline vertical and horizontal hydraulic imbalance problem,to energy saving,generation heat balance purposes.
(3)Environmental protection valve:
In the domestic environmental protection system,the water supply system mainly needs the midline butterfly valve,soft seal gate valve,ball valve and exhaust valve(used to eliminate the air in the pipeline).Sewage treatment system is mainly required to use soft seal gate valve,butterfly valve.
