Can not be ignored in the field of construction valve selection
In building plumbing, the valve acts as a control fluid. Because of the different structure and material, so the valve will be made of different. In order to ensure the piping system to achieve the highest efficiency, lowest cost and longest service life, the correct selection of the valve is essential. The valve has four main functions: to start and stop the flow of media; to regulate the flow of media; to prevent backflow or backflow and to regulate or relieve fluid pressure. The choice of building plumbing system can be based on temperature, media type, temperature and other factors to consider. For example, for high-rise buildings in the fire hydrant control valve should be used signal valve, which is related to the fire hydrant system can be used properly in the fire key, the hydrant system control valve are set to signal valve, and the valve is open The status can be displayed at the Fire Control Center for management to check, and although the cost has been increased, its investment in the entire hydrant system is still minimal and it can significantly increase the safety of the entire hydrant system Still worth it. The choice of valve type in a building plumbing system must be based on the characteristics of the building and if the valve used does not conform to the design features of the building, many potential pitfalls will continue
