The role of the role of sub-catchment watershed is to heat the hot water in each channel separately introduced into the floor radiant heating pipes are laid to achieve sub-room heating and regulate temperature. Catchment is separate cryogenic cooling water after each way to bring together within and attached to the role of the wall or the ground. Watershed and catchment are competent, mediation shunt valves and fittings, exhaust valve, drain valve, head of the terminal plugs and other components. Sub-catchment of the use of effective water management to avoid loopholes, centralized installation and management of water meters, and with a single tube multiplex. Sub-catchment is fitted, water catchment system device used to connect multiple heating pipes, for backwater. Press into the backwater into watershed, catchment two kinds of products, the material is divided into 304 stainless steel and ordinary steel Q235B, Q24R three. ??? Sub-catchment characteristics of the water supply pipe has built-in control valve, the flow rate can be adjusted according to the size of the room. Return pipe to the heat distribution actuators, automatic temperature control, easy to control. Uniform temperature distribution, the steady temperature changes, each room to set their own control. Sub-catchment installation with simple, elegant, solid stand, easy to install, saving installation time and space. 1, in strict accordance with the national standards Atlas "05K232 manifold sub-cylinder" design, the cylinder wall thickness to meet the requirements. 2, based on actual usage, optimize pressure gauges and thermometers interface, easy to install and use, accurate temperature measurement. 3, according to the takeover flanges, use special flange butterfly or welded flange, make sure to match the corresponding flange valves, flanges and valves contact area, high strength, low leakage. 4, all interfaces are polished smooth welding, pressure test before delivery than the national standards to ensure stable operation. 5, do hydrostatic testing before delivery to ensure no leakage during product use. 6, can be designed to collect water separator size according to user needs, to ensure results. Installation Notes: 1 ,? bracket height is determined by the engineering staff, but not more than 1000mm, should be done before the bracket embalmed. 2 ,? cylinder bracket should meet the requirements of thermal expansion and contraction, should be fixed at one end and the other end using the activity or sliding? Stents, stent expansion and contraction of work to ensure that state. 3 ,? operating pressure exceeds 1.0MPa, between the sub-catchment cylinder valve and pressure gauge should be installed. Pressure gauge and valve design is selected according to the technical specifications. ???

[Sub-catchment] Product Overview sub-catchment for water system, all the way to the water manifold is dispersed into several output devices, and multiple water catchment sucked again bring together all the way to the output device. Structure is generally competent, shunt branch pipes, sewage outfall, vent, pressure gauges, thermometers and other components. Larger diameter cylinder bore someone upload or hand holes. Material from carbon steel or stainless steel plate rolling, or seamless steel pipe is made to withstand a certain pressure, the outer surface corrosion and thermal insulation do. Set on the cylinder out of the trap needed to connect multiple pipes, the water can be brought together the brightest or the way the water diversion, is equipped with a pressure gauge and a thermometer on the cylinder, the cylinder body can easily observe the flow state. The lower end of the cylinder is fitted outfall for the sewage outflow when cleaning the barrel. [] Product Selection sub-catchment and calculate a, cylinder diameter than the diameter of a large soda Explorer than two numbers. 2, the general flow rate is calculated according to flow through the cylinder, the water flow rate and generally 0.1m / s ------ 1.0m / s. 3, according to the number of takeover barrel length L, the diameter of the tube spacing calculated, L = 130 + L1 + L2 + L3 + Li + 120 + 2h cylinder when necessary insulation l = d1 + d2 + 120 cylinder is not required insulation l = d1 + d2 + 80 4, the barrel drainage pipe and outfall orientation is determined by the engineering design. ] [Sub-catchment cylinder diameter, design pressure and wall thickness of more than head unit mm, the blue sky company according to the specific needs of a variety of customized manifolds.
