[0002] The manifold is a device that collects and distributes the supply and return water, regulates and controls the flow, and can manually or automatically remove the gas from this part. In the floor heating system, the manifold is divided into two parts: the manifold and the manifold. The manifold is a water distribution device used to connect the water supply pipes of each heating pipe. Its main function is to distribute the hot water from the pipe network system to each room that needs floor heating through the floor heating pipes buried under the floor; the manifold is a water collection device used to connect the return pipes of each heating pipe.

[0003] Conventional manifolds are mainly composed of three parts: a manifold, a collector, and a fixed bracket, including manifold main pipes, collector main pipes, shunt regulator control valves, exhaust valves, main pipe plugs and other components. Due to the fixed lengths of the manifold main pipes and the collector main pipes, manifolds are usually installed in an integrated manner and the number of installation interfaces is limited. Therefore, in some cases where the installation environment is more complex, the installation flexibility of the integrated manifold is relatively low. The patent with application number CN201720123594.4 discloses a split manifold, whose structure includes a water collecting main pipe, and the water collecting main pipe has multiple connectors, multiple water diversion ball valves corresponding to the connectors, and the water diversion ball valves are tightly combined with the water collecting main pipe. This patent only splits the connector on the main pipe into two parts, and does not solve the problem that the manifold needs to be installed in an integrated manner. Utility Model Content

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 5 As shown, the split manifold includes a manifold 110, a manifold 120 and a fixed bracket 130 connecting the two. The fixed bracket 130 fixes the entire manifold on the wall, wherein the manifold 110 is composed of a water supply pipe, a flow regulating valve 111 and a water supply pipe joint 112, and the manifold 120 is composed of a return water pipe, a temperature control valve 121 and a return water pipe joint 122. The water supply pipe and the return water pipe are of split modular design, and are both composed of a plurality of pipe connection modules 200 and an interface module 300 and a port module 400 at both ends.

[0026] like Figures 2 to 3 As shown, the pipe connection module 200 is a cubic block structure as a whole, with a pipe connection inner cavity 250 penetrating through the center, and the pipe connection inner cavity 250 is a pipe for water flow to pass through. A valve interface 230 is downwardly provided on the top of the pipe connection module 200. If the pipe connection module 200 is installed on the water distributor 110, the valve interface 230 is fixedly connected to the flow regulating valve 111; if it is installed on the water collector 120, the valve interface 230 is fixedly connected to the temperature control valve 121.

[0027] A water pipe interface 240 is provided upwardly at the bottom of the pipe connection module 200. Similarly, if it is on the water distributor 110, the water pipe interface 240 is connected to the water supply pipe joint 112; if it is on the water collector 120, the water pipe interface 240 is connected to the return pipe joint 122. The connection between the valve interface 230 and the flow regulating valve 111 or the temperature control valve 121, and between the water pipe interface 240 and the water supply pipe joint 112 or the return pipe joint 122 are all detachable threaded connections, which are convenient for inspection and replacement during actual installation and maintenance.

[0028] The left and right ends of the pipe connection module 200 are respectively provided with a pipe connection interface 210 inwardly and a pipe connection joint 220 outwardly, an interface internal thread 211 is provided on the inner side wall of the pipe connection interface 210, and a joint external thread 221 is provided on the outer side wall of the pipe connection joint 220, and the interface internal thread 211 and the joint external thread 221 cooperate with each other, that is, the pipe connection interface 210 and the pipe connection joint 220 cooperate with each other, so that the manifold can realize the series connection of multiple pipe connection modules 200, and the multiple sections of pipe connection inner cavity 250 are combined head to tail to form a water supply main or a return water main.

[0029] Further, a weight-reducing hole 260 is formed between the outer wall of the pipe connection module 200 and the pipe connection inner cavity 250, and the weight-reducing hole 260 is located at the four corners of the pipe connection module 200 and is arranged parallel to the pipe connection inner cavity 250. The weight-reducing hole 260 can not only make the pipe connection module 200 lighter while ensuring the structural strength of the pipe connection module 200, but also reduce the waste of manufacturing materials and reduce production costs.

[0030] like Figure 4 As shown, the interface module 300 is formed with a pipe joint 220 at one end facing the pipe connection module 200, and a water supply and return interface 310 is formed at the other end, the pipe joint 220 on the interface module 300 is connected to the central water flow cavity of the water supply and return interface 310, and an interface end cover 320 is formed on the outer side between the pipe joint 220 and the water supply and return interface 310, and the cross section of the interface end cover 320 is consistent with the cross section of the pipe connection module 200. The interface module 300 is located at one end of the chain module group of the pipe connection module 200, with the interface end cover 320 as the starting or ending structure, wherein the water supply and return interface 310 is connected to the water supply pipeline on the water distributor 110, and is connected to the water return pipeline on the water collector 120.

[0031] like Figure 5 As shown, the port module 400 is provided with a pipe connection interface 210 at one end facing the pipe connection module 200, and the other end is an arc-shaped closed structure. The port module 400 is provided with an exhaust valve 410 at the top and a drain valve 420 at the bottom. A drain port 421 extends from the side of the drain valve 420, and a pressure gauge 430 is installed on the front between the exhaust valve 410 and the drain valve 420. The exhaust valve 410 and the drain valve 420 can be connected to an automatic controller to realize automatic exhaust and drainage, and the pressure gauge 430 is used to detect and display the air pressure inside the water distributor 110 and the water collector 120 in real time and whether there is leakage.

[0032] like Figures 2 to 5 As shown, the interface module 300 and the pipe connection module 200, the multiple pipe connection modules 200, and the port module 400 and the pipe connection module 200 are all detachably connected through threaded connections. Since threaded connections are prone to loosening and misalignment, locking structures 500 are provided on the upper and lower end faces of each module to improve the connection strength and connection stability of the module combination.

[0033] The locking structure 500 includes a connecting lock 510 and a locking groove 520. Taking the locking structure 500 on the upper end face as an example, the connecting lock 510 includes a semicircular tenon 511 at the upper end and a locking bottom block 512 at the lower end. A square mortise 513 is provided on the side flush with the semicircular tenon 511 and the locking bottom block 512. A raised square tenon 523 is formed on the root end face of one side of the pipe joint 220. The square tenon 523 cooperates with the square mortise 513 to lock together so that the connecting lock 510 is fixedly connected to the root end face of one side of the pipe joint 220. The locking groove 520 is provided on the end surface of one side of the pipe connection interface 210, and the locking groove 520 includes a semicircular tenon 521 at the upper end and a bottom block slot 522 at the lower end, and the semicircular tenon 511 and the semicircular tenon 521, the locking bottom block 512 and the bottom block slot 522 cooperate with each other to fix and limit the connection between the pipe connection interface 210 and the pipe connection interface 210. The locking structure 500 at the lower end surface is symmetrically arranged with the upper end surface.

[0034] To further illustrate, a joint sealing ring 222 is installed at the root of the joint external thread 221. When the pipe joint 220 is connected to the pipe joint interface 210 through the locking structure 500, the joint sealing ring 222 seals the connection so that the water flow in the pipe joint inner cavity 250 will not overflow from the connection.

[0035] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
