Classification features

In terms of function and structure, the manifold is divided into three types: basic type, standard type and functional type.

Basic type: consists of water distribution main pipe and water collection main pipe. A ball valve is installed on each branch port of the main manifold, and a manual exhaust valve is installed on the main manifold. The basic water divider does not have the function of flow adjustment.

Standard type: The structure of the standard type sub-catchment is the same as the basic type, except that the ball valve on each main pipe is replaced by a flow regulating valve. Replace the manual exhaust valves on the two main pipes with automatic exhaust valves. The standard sub-catchment can make precise adjustments to the flow of each loop, and even the flow adjustment of the deluxe standard sub-catchment can be adjusted by artificial intelligence.

Functional type: In addition to all the functions of the standard type manifold, the functional manifold also has temperature and pressure display functions, automatic flow adjustment functions, automatic water mixing and heat exchange functions, thermal energy metering functions, and automatic indoor zone temperature control Function, wireless and remote control function.

In order to prevent corrosion, the manifold is generally made of corrosion-resistant pure copper or synthetic materials. Commonly used materials include copper, stainless steel, nickel-plated copper, nickel-plated alloy, and high-temperature resistant plastics. The inner and outer surfaces of the manifold (including connectors, etc.) should be smooth, free of cracks, blisters, cold barriers, slag inclusions, unevenness defects, and connectors with electroplated surfaces should have uniform color, firm plating, and no deplating defect.

Composition structure

As a water distribution and collection device that connects each loop heating pipe to supply and return water, the manifold is a piece of equipment in the floor heating system and plays a pivotal role. The manifold is composed of three parts: the manifold, the collector and the fixed bracket. Including the main pipe of the water separator (main bar), the main pipe of the water collector (main bar), the branch regulator control valve, the exhaust valve, the main pipe plug, the wall panel and the panel (the bracket type sub-catchment has no panel) and other components. The main accessories are water separator, water collector, filter, valve, air release valve, lock valve, joint head, inner joint head, and heat meter.

The function of setting the exhaust valve (vent valve) on the manifold is to bring convenience to the user during use and avoid air collection caused by factors such as cold and hot pressure difference and water supplementation, which will hinder the operation of the system. With the exhaust valve (vent valve), the air can be released in time. There are two types of manual or automatic exhaust valves. Install an automatic exhaust valve as much as possible.
