[0002] The manifold is a device used to connect the main water supply pipe and return pipe of the heating system. It 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 in the water system. The manifold is a water collection device used to connect the return pipes of each heating pipe in the water system.

[0003] At present, there is a method and system for preventing and controlling condensation in cold and warm water distribution and collection, such as the publication number CN113465005A, which discloses that the water distribution and collection device is composed of a number of split-type transverse multi-channel modules, and the transverse multi-channel module includes an inner transverse tube body and an outer transverse tube body connected inside and outside, and between the inner transverse tube body and the outer transverse tube body are four sections of outer jacket annular cavities separated by four corner transversely fastened tube walls, and the outer jacket annular cavities are filled with thermal insulation foam cotton, and the thermal insulation foam cotton is used to isolate heat conduction and prevent condensation on the outer surface of the water distribution and collection device. However, the filling of the thermal insulation foam cotton generally needs to be filled very thickly to have a good thermal insulation effect, and the water distribution and collection device itself is a relatively small square shape, so the space of the outer jacket annular cavity on its inner wall will not be very large, so the overall thermal insulation effect is not good, resulting in condensation outside the water distribution and collection device.

By setting the third side wall to be formed by four arc-shaped walls, the third reinforcement strip and the fourth reinforcement strip are respectively connected to the hole wall and the second side wall of the water hole, so that the diversity module has a stable and sufficient feeding speed when forming the third side wall in the mold, and can better form the third side wall, reduce the phenomenon of damage to the third side wall during molding, so that the diversity module forms a better and more complete first insulation cavity and second insulation cavity, so as to reduce the convection conduction of heat in the insulation cavity and increase the insulation effect of the diversity module. 4. The hole wall of the water hole protrudes toward the water channel, shortening the distance between the water hole orifice and the regulating valve stem, which can reduce the length of the regulating valve stem and reduce the weight of the regulating stem. Since the upper end of the reset spring always rests on the lower end face of the clamping ring to apply an upward force to the regulating valve stem, reducing the weight of the regulating valve stem can reduce the gravity on the reset spring and make the regulating valve more stable. 5. The water flow valve seat is fixed on the valve core mounting hole, and the water flow outlet is located in the valve core mounting hole, that is, the water flow outlet is opposite to the hole wall of the valve core mounting hole, so as to prevent the water flow in the water flow channel from impacting the water flow outlet, so that the water flow can flow steadily into the metering valve core through the gap between the water flow outlet and the valve core mounting hole, so that the metering valve core can respond to the reading more accurately and timely.

DETAILED DESCRIPTION

[0025] 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.

[0026] It should be noted that the descriptions of the present invention regarding directions such as “up”, “down”, “left”, “right”, “top” and “bottom” are all defined based on the relationships between the orientations or positions shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device must be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. Embodiment 1:

[0027] like Figures 1 to 3 As shown, this embodiment is a split anti-condensation manifold, which includes a manifold and a collector, wherein the manifold and the collector both include a plurality of integrally formed diversity modules 1, the number of which can be freely combined and fixed as needed, and a plurality of diversity modules 1 are fixed together by a long screw rod, and the two adjacent end faces of the diversity module 1 have a boss 1016 and a groove 1017 for positioning, and the module is fixed to a fixed plate or a wall by a module bracket 16.

[0028] The diversity module 1 includes a first side wall 101 and a second side wall 102. The first side wall 101 has a water passage 104. A third side wall 103 is formed between the first side wall 101 and the second side wall 102. An axially penetrating first heat-insulating cavity 105 is formed between the third side wall 103 and the first side wall 101. An axially penetrating second heat-insulating cavity 106 is formed between the third side wall 103 and the second side wall 102. The first heat-insulating cavity 105 and the second heat-insulating cavity 106 bypass the water passage 104 from the inside to the outside to form two hollow layers. A sealing groove 1015 is formed on one end face of the first side wall 101, and the other end is a plane. When the diversity module 1 is assembled, one end of the plane can cooperate with the sealing ring in the sealing groove 1015 to form a sealing structure to prevent water in the water passage 104 from leaking into the first heat-insulating cavity 105. The middle part of the diversity module 1 is provided with a valve core installation hole 107 and a water hole 108 with the same axis. The diameter of the valve core installation hole 107 is larger than the outer diameter of the hole wall of the water hole 108. The axis of the valve core installation hole 107 and the water hole 108 is perpendicular to the axis of the water passage 104. The hole wall of the water hole 108 protrudes toward the water passage 104. Four fixed cylinders 109 are formed on the second side wall 102 and are evenly distributed in the circumferential direction relative to the water passage 104. The fixed cylinders 109 have fixed holes 1010 therein and are located on both sides of the valve core installation hole 107 and the water hole 108. The first heat insulation cavity 105 and the second heat insulation cavity 106 surrounding the water passage 104 are formed on the diversity module 1. The second heat insulation cavity 106 surrounds the outer circle of the first heat insulation cavity 105 to reduce the convection conduction of heat in the heat insulation cavity, thereby increasing the heat insulation effect of the diversity module 1 and better preventing condensation on its outer surface.

[0029] Since the third side wall 103 is relatively thin, a plurality of first reinforcing strips 1011 are formed between the first side wall 101 and the third side wall 103, and a plurality of second reinforcing strips 1012 are formed between the second side wall 102 and the third side wall 103. The first reinforcing strips 1011 and the second reinforcing strips 1012 are provided in a conjoined manner. That is, the first reinforcing strips 1011 and the second reinforcing strips 1012 are integrally formed, and bosses 1016 and grooves 1017 may be provided on the end surfaces of the first reinforcing strips 1011 and the second reinforcing strips 1012. Embodiment 2:

[0030] like Figure 4As shown, the structure and principle of this embodiment are basically the same as those of the first embodiment, except that: in this embodiment, in order to better shape the third side wall 103, the first reinforcement strip 1011 and the second reinforcement strip 1012 are arranged at intervals, one of the first reinforcement strips 1011 is connected to the hole wall of the valve core installation hole 107, one of the first reinforcement strips 1011 is connected to the hole wall of the water hole 108, and the second reinforcement strip 1012 is connected to the fixed cylinder 109. The first reinforcement strip 1011 and the second reinforcement strip 1012 are arranged at intervals and staggered to ensure sufficient space for the first insulation cavity 105 and the second insulation cavity 106, and to ensure that the diversity module 1 has a stable and sufficient feeding speed when the third side wall 103 is formed in the mold, so that the third side wall 103 can be better formed, and the phenomenon of damage to the third side wall 103 during molding can be reduced, so that the diversity module 1 forms a better and more complete first insulation cavity 105 and second insulation cavity 106, so as to reduce the convection conduction of heat in the insulation cavity and increase the insulation effect of the diversity module 1. Embodiment three:

[0031] like Figure 5 As shown, the structure and principle of this embodiment are basically the same as those of the first embodiment, except that: in this embodiment, the third side wall 103 is also formed in a better manner. The third side wall 103 is configured to be formed by four arc-shaped walls, and two adjacent arc-shaped walls are connected to form a plurality of third reinforcement strips 1013 and fourth reinforcement strips 1014, one of the third reinforcement strips 1013 is connected to the first side wall 101 and the hole wall of the valve core installation hole 107, one of the third reinforcement strips 1013 is connected to the first side wall 101 and the hole wall of the water hole 108, and the fourth reinforcement strip 1014 is connected to both the first side wall 101 and the second side wall 102. The arc-shaped wall enables the diversity module 1 to be fed smoothly when the third side wall 103 is formed in the mold, thereby ensuring the feeding speed, reducing stress concentration, and better forming the third side wall 103, reducing the phenomenon of damage to the third side wall 103 during forming, so that the diversity module 1 can form a better and more complete first insulation cavity 105 and second insulation cavity 106, thereby reducing the convection conduction of heat in the insulation cavity and increasing the insulation effect of the diversity module 1. Embodiment 4:

[0032] like Figure 6As shown, a plurality of sub-modules 1 are installed with water collecting branch valves to form a water collector, wherein the water collecting branch valve includes a regulating valve seat 2 and a regulating valve cover 3 that are fixedly connected by threads, a spring seat 4 and a gasket 5 are fixed against the regulating valve seat 2 and the regulating valve cover 3 from top to bottom in sequence, a reset spring 6 and a regulating valve stem 7 are arranged in the spring seat 4, one end of the regulating valve stem 7 extends out of the regulating valve cover 3 and is located in the handle seat 8, and the other end extends out of the regulating valve seat 2 and is located in the water passage 104 and is opposite to the water passage hole 108, a clamping ring 9 is arranged on the regulating valve stem 7, the clamping ring 9 is located in the spring seat 4, the reset spring 6 is located between the clamping ring 9 and the gasket 5, a sealing member 10 is arranged between the lower end surface of the gasket 5 and the regulating valve seat 2, a sealing member 2 11 is arranged between the upper end surface of the spring seat 4 and the regulating valve cover 3, the sealing members 10 and 11 are both sleeved on the regulating valve stem 7, and the regulating valve seat 2 is threadedly fixed on the valve core mounting hole 107. The upper end of the handle seat 8 is fixedly sleeved with a rotating wheel 12, and the lower end of the handle seat 8 is rotatably connected to a handle sleeve 13 through a thread. The lower end of the rotating wheel 12 and the handle sleeve 13 are rotatably embedded in each other through a buckle, and the lower end of the handle sleeve 13 is fixedly connected to the regulating valve seat 2 through a thread.

[0033] The rotating wheel 12 is rotated to drive the handle seat 8 to rotate, and the handle seat 8 moves downward or upward along the handle sleeve 13 to drive the regulating valve stem 7 to move. The hole wall of the water hole 108 protrudes toward the water passage 104, shortening the distance between the hole of the water hole 108 and the regulating valve stem 7, reducing the length of the regulating valve stem 7, and reducing the weight of the regulating stem. Since the upper end of the reset spring 6 always abuts against the lower end surface of the clamp ring 9 to apply an upward force to the regulating valve stem 7, reducing the weight of the regulating valve stem 7 can reduce the gravity on the reset spring 6, making the water collection branch valve more stable.

One end of the adjusting valve core 15 extends into the water flow hole 108.

[0035] The water-passing valve seat 14 is provided with a fixed section 1401 and a water-inlet section 1402, and the diameter of the water-inlet section 1402 is smaller than the diameter of the fixed section 1401.
