[Products] manifold from the cylinder, head, take over and accessories (reinforcement rings, flanges) components. Manifold is the way the water through a container divided into several output devices, and multiple water catchment device sucked through a container all the way out of the main material used [1], cylinder: When the sub-catchment The design pressure of less than or equal 1.6MPa selection of Q235B (calculated according to the data presented in this standard Q235B); when making design pressure greater than and less than 1.6MPa 2.5MPa, the cylinder material selection 20R or 16MnR .. Selection of 20 steel seamless pipe for the barrel when using the material, the choice of superior material properties. 2, head: Press the "steel pressure vessel head" JB / T4746 choice. Its the same with the cylinder wall thickness, material requirements and the same cylinder or match. 3, flange: flange valve flange should match with project selection, press the "steel pipe flanges" selection. Manufacturing requirements [1], the largest in the cylinder opening hole diameter should be less than 0.5 times the inside diameter of the barrel; after the tube spacing between the insulation should be not less than 100mm. 2, when the cylinder diameter is 1000mm can open manhole according to project needs, to take over the openings need to be reinforced. 3, all welding work must be 4 by holding the appropriate certificates of welders, welding after the completion shall be 1.25 times the catchment divide the design pressure of the pressure test. After passing the test, excluding internal water, dry stains, temporary closure of the flange to prevent debris from entering. After the completion of manufacture rust, brushing the outer surface rust twice. Installation Requirements [1], after sub-cylinder or sub-catchment to enter the construction site, must be shared for acceptance by supervision, construction unit, check two, their product quality certification and related inspection reports (including NDT weld inspection reports, strength test records, etc.), and its appearance inspection, after passing before installation. 3, bracket height and form the basis of a decision by the engineering staff, stand height of not more than 1000mm, stand divided channel, saddle, etc., should be carried out before the bracket rust treatment, two anti-rust paint brush, paint brush outside . Sub-catchment is one of the central air conditioning system inside the product, which is different from other air conditioning system heat exchanger groups, such as the inside of a vacuum degasser products, sub-catchment is mainly used for water system. Manifold is the way the water dispersed into several output devices, and the catchment is multiple water pooled in one output device. Structure is generally competent, shunt branch pipes, sewage outfall, vent, pressure gauges, thermometers and other components of larger diameter cylinder bore someone upload or hand hole, made from rolled carbon steel plate, or made of seamless steel tubes, can withstand a certain pressure, the outer surface treated with preservatives or insulation. Set on the cylinder out of the trap needed to connect multiple pipes, the water can be brought together the brightest or the way water diversion is equipped with a pressure gauge or 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 and calculation method of sub-catchment. In the selection of the above, we should pay attention to the cylinder diameter than the diameter and larger mains soda two numbers. In the calculation method is generally sub-catchment flow rate can be calculated from flow through the cylinder, the water flow rate and generally 0.1m / s ---- 1.0m / s based on barrel length L to take over the number, diameter, tube spacing is calculated, the specific formula is L = 130 + L1 + L2 + L3 + Li + 120 + 2h, when necessary insulation cylinder l = d1 + d2 + 120, when the cylinder is not required insulation l = d1 + d1 + 8 , drainage pipe and outfall on the orientation of the cylinder is determined by the engineering design. Manifold (LTFJ-1585) Blue Sky card set manifold is a combination of water flow distribution manifold and manifold made and will set devices. Manifold is the way the water through a container divided into several output devices, and multiple water catchment device sucked through a container all the way to the output. Several of its management branch pipes, respectively, including backwater branch and branch water, its larger and more for DN2000-DN1500 ranging from carbon steel or stainless steel plate, are professional manufacturer of pressure vessels, which will need to install a pressure gauge thermometer . On the one hand the main pipe water flow distribution as necessary to ensure that the regional branch of the loop flow to meet the load needs, but also to bring together the various branches of the water loop, and the input backwater trunk tube recycling operation. Its backwater recycling, more energy-saving effect can be achieved, can meet the heating and cooling needs, which are widely used in boilers, central air conditioning, industrial cooling water systems, hot water systems. Can customize a variety of points, catchment according to customer needs. Catchment (LT-FJ-83589) blue card set manifold is a combination of water flow distribution manifold and manifold made and will set devices. Manifold is the way the water through a container divided into several output devices, and multiple water catchment device sucked through a container all the way to the output. Several of its management branch pipes, respectively, including backwater branch and branch water, its larger and more for DN350-DN1500 ranging from carbon steel or stainless steel plate, are professional manufacturer of pressure vessels, which will need to install a pressure gauge thermometer . On the one hand the main pipe water flow distribution as necessary to ensure that the regional branch of the loop flow to meet the load needs, but also to bring together the various branches of the water loop, and the input backwater trunk tube recycling operation. Its backwater recycling, more energy-saving effect can be achieved, can meet the heating and cooling needs, which are widely used in boilers, central air conditioning, industrial cooling water systems, hot water systems. Can customize a variety of points, catchment according to customer needs. Sub-catchment integral manifold by a device to warm the system by watershed managers and executives composition catchment, watershed executives connected to the water supply pipe network system, its main role is to come from the heat pipe network system water through buried under the floor heating pipes allocated to each room interior floor heating needs. Warm water flowing in the tube, it will transfer heat to the floor, and then radiate heat into the room through the floor.
