Description

Technical Field

[0001] The utility model relates to the technical field of water collectors, in particular to a flow-balanced combined water collector. Background Art

[0002] The manifold is a water distribution and collection device used to connect the supply and return water of each heating pipe in the water system. It is divided into manifolds and manifolds according to the inlet and return water. The combined manifold is a modular liquid distribution and collection system that allows users to configure and adjust the scale and function of the manifold according to specific application requirements. This type of manifold is usually used in heating, cooling, industrial water treatment and other fields. Its main purpose is to achieve uniform distribution and collection of fluids and flow balance of the system.

[0003] For example, the Chinese patent "CN216644333U" discloses a combined manifold, which proposes: a sliding fixed block is fixedly installed on one side of the mounting bracket; a plurality of sliding fixed blocks are provided, and a clamp is fixedly installed on each sliding fixed block; four clamps are provided, two in a group, and the two groups of clamps are used to fix the manifold and the manifold respectively; the manifold and the manifold are composed of the same structure, wherein the manifold is located above the manifold. A built-in filter mesh sleeve is provided in the manifold, which can intercept impurities or scale in the water during water supply to prevent it from entering the heating pipe, thereby ensuring the cleanliness of the circulating water body and avoiding the situation where scale in the pipe causes poor water circulation: one end of the built-in filter mesh sleeve is fixedly connected to the end cap, which greatly facilitates the disassembly and cleaning of the built-in filter mesh sleeve.

[0004] It can be seen from the above-mentioned device that although the above-mentioned effective method for filtering and cleaning impurities inside the water separator is proposed, the current technical solution still has the following shortcomings:

[0005] During the heating process, the existing manifold and water distributor has uneven flow at each water outlet, resulting in temperature errors at each heating point. When the water supply pressure changes, a water hammer effect will occur, causing damage to the inside of the manifold and water distributor. When the water pressure is too low, water only flows to the water outlet close to the water inlet, and water cannot flow through the water outlet that is farther away, resulting in poor heating balance and affecting the service life. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a flow-balancing combined water collector, which has the advantage of effectively reducing the water hammer effect caused by changes in water pressure to protect the pipeline through the setting of the main valve core, and when the water pressure is low, the main valve core is supported by the spring to close the water inlet until it opens after the water flow in the pipeline is large and the water pressure increases, thereby effectively preventing the flow of several water outlets from being unbalanced. This solves the problem that during the heating process, the flow of each water outlet of the existing water collector and manifold is unbalanced, resulting in temperature errors at each heating point, and when the water supply pressure changes, a water hammer effect will occur to damage the inside of the water collector and manifold, and when the water pressure is too low, water will only flow to the water outlet close to the water inlet, and water cannot flow through the water outlet that is farther away, resulting in poor heating balance and affecting the service life.

[0018] Beneficial effects:

[0019] 1. The flow-balanced combined water collector can effectively prevent damage to the inside of the water collector due to the instantaneous large flow impact when the system is just started by limiting the movement of the main valve core through the sleeve rod, and effectively prevent the water hammer effect caused by normal valve closure, effectively extending the service life of the water collector.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 , flow-balanced combined water collector, including a mounting frame 1, characterized in that: an upper water distributor 2 and a lower water distributor 3 are installed on the upper and lower sides of the mounting frame 1, and the upper water distributor 2 and the lower water distributor 3 are the core parts of the water collector, responsible for the distribution and collection of liquid. They have similar structures, and a flow channel is arranged inside to guide the flow of liquid. The upper water distributor 2 and the lower water distributor 3 are both provided with an adjustment component 4. The upper water distributor 2 is provided with a water inlet 21 on the left side, which is used to connect an external water source or a liquid supply system. The design of the water inlet 21 usually takes into account the inflow mode and flow requirements of the fluid to ensure the smooth entry of the fluid. A plurality of water outlets 22 are provided below the outer wall of the upper water distributor 2, which are used to output the evenly distributed fluid to each branch of the system. A ball valve 23 is arranged inside the water outlet 22, and the ball valve 23 is used to control the on-off and flow regulation of the fluid. A pressure relief valve 24 is arranged above the outer wall of the upper water distributor 2.

[0029] See also Figure 2-4 The regulating assembly 4 includes a main valve core 45, which is arranged inside the upper water distributor 2. The outer wall of the main valve core 45 is fixedly connected with a piston rod 44. When the piston rod 44 moves, it will drive the main valve core to move together, thereby adjusting the passage area of ​​the fluid. The outer wall of the piston rod 44 is provided with a spring 43, and the spring 43 is fixedly connected to the inner wall of the sleeve rod 42. The piston rod 44 is movably installed inside the sleeve rod 42. The function of the spring 43 is to provide a constant force, so that the piston rod 44 and the main valve core 45 are kept in a certain position to ensure the stable flow of the fluid. A support rod 41 is arranged below the sleeve rod 42, and the support rod 41 is fixedly connected to the inner wall of the upper water distributor 2. The inner wall diameter of the water inlet 21 is smaller than the inner wall of the upper water distributor 2. The inner wall of the water inlet 21 is sealed and fitted to the main valve core 45. The outer wall of the main valve core 45 is provided with a tooth plate 46, and the tooth plate 46 passes through the surface A number of gears 47 are installed in the meshing engagement of the latch teeth. When the main valve core 45 moves, the tooth plate 46 will drive the gear 47 to rotate. A limit rod 49 is fixedly connected above the gear 47, and the limit rod 49 is movably installed inside the limit base 410. The limit base 410 is fixedly connected to the inner wall of the upper water distributor 2. A screw rod 48 is fixedly connected to the lower outer wall of the gear 47. The screw rod 48 is installed with an auxiliary valve core 411 through surface thread meshing. The auxiliary valve core 411 is sealed and fits the inner wall of the water outlet 22. When the gear 46 rotates, it will drive the screw rod 48 to rotate, thereby driving the auxiliary valve core 411 to move along the inner wall of the water outlet 22. The auxiliary valve core 411 is also set to a cone, which is sealed and fits the inner wall of the water outlet 22 to adjust the flow rate of the outflowing fluid. The main valve core 45 and the auxiliary valve core 411 are both set to a cone, and the outer walls of every two auxiliary valve cores 411 are fixedly connected with a connecting rod 412.

[0030] Working principle: First, after the water collector is installed, when there is no water flow, the main valve core 45 is tightly fitted on the inner wall of the water inlet 21 due to the support force of the spring 43. At this time, the water outlet 22 is also in a closed state. When water flows from the water inlet 21 into the upper water distributor 2, when the water flow is small, the main valve core 45 on the outer wall of the piston rod 44 is still sealed and fitted to the inner wall of the water inlet 21 through the support force of the spring 43. After the water flow in the pipeline is accumulated and the water pressure increases, the pressure of the spring 43 is exerted on the The main valve core 45 is pushed inward to move the main valve core 45 to the interior of the upper water distributor 2, and the water flows into the interior of the upper water distributor 2 through the gap between the main valve core 45 and the water inlet 21. On the contrary, when the water pressure is relatively large, the piston rod 44 is limited by the sleeve rod 42 to keep the main valve core 45 at the same opening and closing degree, so that the water still enters the interior of the upper water distributor 2 at a uniform speed, avoiding the water flow from impacting the internal components of the upper water distributor 2, and effectively preventing the occurrence of water hammer effect, thereby effectively protecting the interior of the upper water distributor 2 and extending the service life.

[0031] Secondly, when the main valve core 45 is pushed by the water flow, the main valve core 45 drives the tooth plate 46 arranged on its outer wall to move, and the tooth plate 46 drives the plurality of gears 47 to rotate through the surface teeth, and the plurality of gears 47 rotate and drive the screw rod 48 below to rotate. When the screw rod 48 rotates, since the plurality of auxiliary valve cores 411 are connected in series with each other through the plurality of connecting rods 412, the plurality of auxiliary valve cores 411 meshed with the screw rod 48 through the inner wall thread are moved upward through the rotation of the screw rod 48, so that the auxiliary valve core 411 is adjusted according to the degree of opening and closing of the main valve core 45, and the main valve core 45 is adjusted according to the size of the water pressure. The degree of opening and closing is adjusted. When the water flow is large to ensure balanced distribution of each water outlet 22, the moving distance of the main valve core 45 becomes larger. At the same time, the moving distance through the tooth plate 46 increases, and each auxiliary valve core 411 is also fully opened, so that each water outlet 22 can discharge water evenly with the maximum water flow. This design can ensure that under high flow conditions, the water collector can still maintain a balanced distribution of flow to avoid local overload or underload. When the water flow is small, the moving distance of the tooth plate 46 driven by the auxiliary valve core 411 is also reduced accordingly, and the auxiliary valve core 411 only moves partially upward to ensure that each water outlet 22 can have a balanced flow under small water flow conditions.

[0032] It is worth mentioning that in addition to achieving balanced distribution of flow, the upper water distributor 2 is also equipped with a pressure relief valve 24 as a safety protection measure. When the system pressure exceeds the preset safety value, the pressure relief valve 24 will automatically open to release part of the pressure to protect the system from excessive pressure. This design can effectively prevent equipment damage or safety accidents caused by excessive water pressure.
