MANIFOLD

The manifold is a water collection device used to connect various heating pipes for supply and return water distribution and water collection. Press the incoming and outgoing water as the water separator and water collector. Therefore, it is called a manifold or water collector, commonly known as a water separator.
The manifold is a water distribution and collection device used to connect various heating pipes to supply and return water in the water system. The water divider used in floor heating and air conditioning systems should be made of brass, and the water divider used in the renovation of the household meter of the tap water supply system is mostly PP or PE. Both the supply and return water are equipped with exhaust valves, and many water separators are also equipped with drain valves. The front end of the water supply should be equipped with a “Y” type filter. Each branch of the water distribution pipe should be equipped with a valve to adjust the amount of water.
use
Water separators are often used for:
1. In the underfloor heating system, the manifold manages a number of branch pipelines, and is equipped with exhaust valves, automatic thermostatic valves, etc., generally made of copper. The caliber is small, between DN25-DN40. There are more imported products.
2. In the air-conditioning water system, or other industrial water systems, several branch pipelines are also managed, including the backwater branch and the water supply branch, but the larger ones are DN350-DN1500, and they are made of steel plates. Professional manufacturing companies for pressure vessels need to install pressure gauges, thermometers, automatic exhaust valves, safety valves, vent valves, etc. A pressure regulating valve must be installed between the two vessels, and an automatic bypass pipeline is required.
3. Tap water supply system, the use of water separator effectively avoids loopholes in tap water management, centralized installation and management of water meters, and the use of single pipe multiple channels reduces the cost of pipe procurement, and greatly reduces the construction time and improves Efficiency. The tap water dispenser is directly connected to the aluminum-plastic main pipe through a reducing diameter, and the water meters are installed in the water meter pool (water meter room) to achieve one meter per household, outdoor installation and outdoor viewing. Currently, household meter reforms across the country are underway on a large scale.
working principle
The water separator in the floor heating system is mainly responsible for the opening and closing of the water flow in the floor heating loop. When the water in the gas boiler flows into the manifold through the main pipe, the impurities are separated by the filter, and then the water is evenly distributed to the loop After the heat exchange, it returns to the water collection back to the main bar, and then flows into the heating system from the return water outlet.
Related experiments
Introduction
In the experiment, the azeotropic mixture distillation method was used, and the organic layer above the water layer formed by the reaction was continuously flowed back into the reaction flask with a water separator, and the water formed was removed. Before the experiment, add water in the water trap to the branch pipe and then put Xml water, that is, there is (V-X)ml water in the water trap. Start heating with a small fire, keep the liquid in the bottle boiled, start to reflux, and control a certain (experimental temperature). When the water trap is fully filled with water, the reaction has been basically completed. Stop heating. Mainly used in chemical experiments to separate the water produced by chemical reactions. Because the water produced by chemical reactions will affect the reaction or make the reaction impossible when water is present in the reaction system, the produced water needs to pass through and azeotrope with water. The reflux of the solvent brings out the water so that the reaction can proceed. Usually toluene and water are used to azeotropically take away the water produced by the reaction.

main content
Subject content and scope of application This standard specifies the performance requirements and test methods of the manifold. This standard applies to water separators for laying fire hoses. The water separator is a fire-fighting equipment that separates the water belt branch line from the water belt main line. Each water divider has an inlet and several outlets.
Scope of application
Computer room auxiliary equipment plays a major auxiliary role in the design and operation of the computer room, ensuring the normal operation of the computer room. It is mainly composed of constant pressure device, water processor, water softener, filter, water tank, balance valve and other equipment. 1 Selection guide for constant pressure device; 2 Selection guide for electronic water processor; 3 Selection guide for water softener.
Technical parameters of water separator
Diameter and length of the water separator, the number and size of the inlet and outlet of the water separator, the working pressure of the water separator, and the material used for the water separator
working principle
The water divider plays a role of splitting. 1. When there are many pipelines, if too many three-way, four-way and other accessories are used, the energy loss of the system is very large. 2. It is convenient for users to operate. When the water separator is adopted, the pipeline direction is clear and easy to operate. 3. Convenient maintenance, the interfaces on the manifold are all flanged, so it can be said that the purpose is to facilitate disassembly and maintenance. 4. Reduce system pressure difference.
Water separator structure
Generally, the manifold is mainly composed of three parts: the manifold, the collector and the fixed bracket. The function of the water separator is to separate the hot water from the heat source into the pipes laid by the ground radiant heating of each road, so as to realize the purpose of heating and adjusting the temperature of the room. The water collector collects the low-temperature water in each channel after separate heat dissipation and fixes it to the wall or the ground.
