Description

Technical Field

[0001] The utility model relates to the field of manifolds, in particular to a heat-insulating spliced ​​manifold. Background Art

[0002] The manifold is a device used to connect the main water supply pipe and return pipe of the heating system. It can distribute, adjust and control the supply and return water. Therefore, the manifold can be divided into two parts: the manifold and the collector. The manifold is a water distribution device used to connect the water supply pipes of various heating pipes in the system. The main body of the manifold is provided with a number of evenly distributed water distribution joints, and each water distribution joint has a valve core assembly that independently controls its own opening and closing. The opening and closing of the water distribution joint is manually or automatically controlled by the valve core assembly.

[0003] It can be seen from this that the hot water in the floor heating system needs to enter the main body of the water distributor and then be distributed to each pipe through the water distribution joint. The main body of the traditional water distributor is an integrated structure, and can only rely on its own wall thickness as an insulation layer to insulate the hot water entering the main body of the water distributor, resulting in a very limited insulation effect. The heat of the hot water can easily pass through the main body of the water distributor to the outside, causing the heat to merge with the outside air. Due to the large temperature difference and humidity in the room, the alternation of hot and cold at this time, the moisture in the air will form condensation on the surface of the metal water distributor body, and condensation water is very easy to produce, resulting in the air duct and hanger being soaked, the air outlet dripping, the ceiling dripping, the wall seepage and mold, the wall paint falling off, etc., which brings many inconveniences to users and building property management, and causes certain economic losses.

[0033] The method of using the utility model is as follows:

[0034] Since the assembly of the water distributor body 1 is composed of a plurality of middle pieces 102 evenly distributed in the axial direction, and a plurality of heat preservation chambers 2 are evenly distributed on the outer ring of the middle piece 102, if the heat of the hot water flowing into the inner space of the middle piece 102 is to be dissipated outward, it needs to pass through a plurality of heat preservation layers formed by the heat preservation chambers 2. Although the heat preservation chamber 2 is a cavity, it has air inside. When the head end piece 101 and the tail end piece 103 are provided at both ends of the assembly, the heat preservation layer formed by the heat preservation chambers 2 intersecting the plurality of middle pieces 102 will be covered by the head end 101 and the tail end piece 103. Part 101 is sealed with tail part 103. At this time, the air in the insulation layer is in a fixed state and will not transfer heat like a fluid. In addition, the thermal conductivity of air itself is extremely low. Therefore, the air in the insulation chamber 2 will become an excellent insulation material, which can ensure to the greatest extent that the insulation chamber 2 can form an insulation layer with excellent insulation effect and achieve insulation effect, thereby effectively preventing the heat of the hot water flowing through the water distributor body 1 from being quickly dissipated to the outside and condensing when it meets the outside air, thereby playing an anti-condensation effect and an anti-condensation effect.

The existence of the upper connecting member 3 and the lower connecting member 4 can effectively support each insulation chamber 2 and avoid deformation of the insulation chamber.

[0036] A water diversion joint 7 which is in communication with the water diversion hole 6 is provided at the lower end of the lower connecting piece 4, a valve core assembly 8 which matches the upper opening of the water diversion hole 6 is provided in the upper mounting hole 5, the upper end of the valve stem of the valve core assembly 8 extends upward to the outside of the upper mounting hole 5 and is provided with a hand wheel 9 or an electric actuator 10. The electric actuator 10 is an existing device, also known as an electric thermostatic controller, which is commonly used in floor heating systems and can automatically control the opening and closing of the valve core assembly.

[0037] The positioning structure includes a left positioning rib 11 arranged on one side of the upper connecting member 3 and the lower connecting member 4, and a right positioning rib 12 arranged on the other side of the upper connecting member 3 and the lower connecting member 4.

The left positioning rib 11 is provided with a positioning hole 13 or a positioning rod 14. The right positioning rib 12 is provided with a positioning rod 14 matching the positioning hole 13 or a positioning hole 13 matching the positioning rod 14.

[0038] When the middle piece that fits with the head end piece 101 or the tail end piece 103 has a positioning rod 14, the head end piece 101 or the tail end piece 103 is provided with an auxiliary hole 15 that matches the positioning rod 14.

The head end piece 101, the tail end piece 103 and the plurality of middle pieces 102 can be connected and fixed by passing the bolts through the first through hole, the plurality of middle through holes 20 and the tail through hole in sequence and screwing on the nuts matching them. At this time, the head of the bolt is tightly pressed on the first limiting part, and the nut is tightly pressed on the tail limiting part. The tightening force at both ends can ensure the stability of the head end piece 101, the tail end piece 103 and the plurality of middle pieces 102 when they are connected and fixed to the greatest extent.

The exhaust valve 24 can exhaust air when the air pressure is too high, thereby ensuring the balance of the air pressure, while the drain valve 25 can drain water when the water pressure is too high, thereby ensuring the balance of the water pressure, thereby ultimately ensuring the normal operation of the floor heating system.

[0042] When the manifold has two manifold bodies 1, the two manifold bodies 1 can be connected and fixed by a bracket 26, so that the two manifold bodies 1 can be installed and fixed by the bracket 26, and the two manifold bodies 1 can adopt different opening and closing methods.
