Household heating types and characteristics of the valve
Most of winter heating area is given priority to with plumbing, whether it be independent heating, or central heating or; Its control effect in heating system pipe fittings or valves, and type of valve has a lot of, is used in heating system is more than ten kinds of, the life is a bit far from us, but life has close relationship with us valve valve is the household heating system, in general can be divided into three kinds, one kind is cut-off valve, ball valve; Below we together to understand the relevant knowledge:
1, the cut-off valve, from the shape can be divided into straight type globe and Angle type globe valve; We usually say in front of the radiator is installed straight and Angle valves, its characteristic is mainly characterized by simple flow, dead zone and vortex area is small, with the help of the valve inside its flushing action, can effectively prevent the media congestion, namely good self-cleaning properties; And small flow resistance, flow coefficient is larger than single seat valve, equivalent to a two-seater valve flow coefficient;
2, ball valve, the valve core to the sphere, the sphere is in the middle of a direct channel, when we put the channel rotation to the heating pipe in the same direction, the water can pass; And when we put the ball core pipe rotates with heating pipes to the vertical direction, the handle closed, it is the main characteristic of the switch size short, as long as we can rotate for 90 degrees solution; Wear-resisting, withstand voltage, strong sealing, long service life and other characteristics;
Above these two valves are commonly used household heating system valve, is common in the market, sometimes is not the same as the name, actually principle is the same, in the radiator in the top right corner of the plug and a vent valve, it is also a kind of stop valve, it is through the rotating bolt to adjust the size of the valve opening; Anyway as long as we used in the valve fully understand their own right, mining can be used in the process to avoid the damage, and problems of the valve can also be to repair or replacement in a timely and effective manner.
