Description

Technical Field

[0001] This utility model relates to the field of water supply and heating equipment technology, specifically to a high-flow-rate manifold. Background Technology

[0002] Currently, metal manifolds used in water supply and HVAC systems generally employ a compression fitting connection structure. Due to structural limitations and strength constraints, their diameter is typically quite small. For example, ball valve-type manifolds have a maximum inner diameter and auxiliary structure diameter of Ф11mm, resulting in relatively small inlet and outlet water volumes, which is unlikely to satisfy users. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a large-flow water manifold, which has a simple structure, is easy to install, has a larger diameter, low water resistance, and larger inlet and outlet flow rates.

[0004] The technical solution adopted to achieve the above-mentioned objectives of this utility model is as follows:

[0005] A high-flow-rate manifold includes a main manifold pipe and one or more branch manifold pipes. Each branch manifold pipe is equipped with a manifold valve, which includes a valve plate and a valve stem for driving the valve plate to rotate. The valve plate is located inside the branch manifold pipe and can rotate within the branch manifold pipe. The valve stem passes through the branch manifold pipe and is perpendicular to the axial direction of the branch manifold pipe. One end of the valve stem is located inside the branch manifold pipe and is fixedly connected to the valve plate. When the valve plate rotates to be parallel to the axial direction of the branch manifold pipe, the side wall of the valve plate makes point contact with the inner wall of the branch manifold pipe, and the manifold valve opens. When the valve plate rotates to be perpendicular to the axial direction of the branch manifold pipe, the side wall of the valve plate makes circumferential contact with the inner wall of the branch manifold pipe, and the manifold valve closes.

[0006] The valve stem includes an inner screw and an outer sleeve. The valve plate is disc-shaped and has a threaded hole on its side wall. The axis of the threaded hole is located radially on the valve plate. The outer sleeve penetrates the side wall of the manifold and is rotatably connected to the side wall of the manifold. The inner screw penetrates the outer sleeve. One end of the inner screw inside the manifold is threadedly connected to the threaded hole of the valve plate, and the other end of the inner screw outside the manifold is fixedly installed on the outer sleeve.

[0007] The aforementioned distribution branch pipe is provided with a first through hole, which is in the form of a two-stage step. The larger diameter part of the first through hole is connected to the inner cavity of the distribution branch pipe. The outer sleeve is in the form of a two-stage step and passes through the first through hole. The outer sleeve and the first through hole are fitted with a clearance fit, and the outer sleeve is limited by the stepped surface of the first through hole.

[0008] The water distribution valve also includes a handle. On the two sides opposite to the handle, there are limiting countersunk holes and limiting slots respectively. The bottom of the limiting countersunk hole is provided with a second through hole. The limiting countersunk hole and the second through hole are coaxial. One end of the outer sleeve is provided with a tenon. The outer sleeve is fixedly connected to the handle through the cooperation of the tenon and the limiting slot. The inner screw passes through the second through hole, and the head of the inner screw abuts against the limiting countersunk hole.

[0009] The side wall of the distribution branch pipe is provided with a limiting boss, and a third through hole is provided on the limiting boss. The outer sleeve passes through the third through hole and is clearance-fitted with the third through hole. A first limiting ring is provided on the side of the handle facing the distribution branch pipe. The first limiting ring is sleeved on the limiting boss and is clearance-fitted with the limiting boss. A limiting block is provided on the side wall of the limiting boss, and a first notch is provided on the first limiting ring to cooperate with the limiting block.

[0010] The valve plate sidewall is provided with a limiting groove, the opening of the threaded hole is located at the bottom of the limiting groove, and the outer sleeve is provided with a limiting protrusion on one end facing the valve plate. The limiting protrusion and the limiting groove are connected in a cooperative manner.

[0011] The aforementioned water distribution valve also includes a limiting component, which includes a second limiting ring and a locking ring. The inner wall of the distribution branch pipe is stepped. The second limiting ring is located inside the distribution branch pipe. The outer wall surface of the second limiting ring is in contact with the inner wall surface of the distribution branch pipe. The end face of the second limiting ring facing the main distribution pipe abuts against a stepped surface of the distribution branch pipe. A second notch is provided on the end of the second limiting ring facing the main distribution pipe. The second notch abuts against the end of the outer sleeve facing the valve plate. The valve plate is rotatably connected to the second limiting ring. The locking ring is located inside the distribution branch pipe and is fixedly connected to the distribution branch pipe. The locking ring abuts against the end of the second limiting ring facing away from the main distribution pipe.

[0012] The locking ring is provided with external threads, the inner wall of the distribution branch pipe is provided with internal threads, the locking ring is threadedly connected to the distribution branch pipe, and a sealing ring is provided between the locking ring and the distribution branch pipe.

[0013] The locking ring has a flange at one end facing away from the second limiting ring, and the flange is in contact with a stepped surface of the distribution branch pipe.

[0014] Compared with the prior art, the beneficial effects and advantages of this utility model are as follows:

[0015] 1. This manifold replaces the traditional ball core type manifold valve with a hinged type manifold valve. The hinged type manifold valve mainly includes a valve plate and a valve stem (shaft) at the center. By rotating the valve stem 90 degrees, the valve plate is rotated, so that the valve plate and the inner wall of the manifold branch pipe go from point contact to circumferential contact, thus achieving the purpose of opening and closing the manifold valve.

[0016] 2. After the structure of the water distribution valve of the manifold is changed, the diameter of the manifold branch pipe can be made larger, the water resistance is smaller, and the inlet and outlet flow rates are larger.

[0017] 3. The structure of this water manifold is simple, eliminating the need for cumbersome sealing and connection mechanisms, making production and processing simpler and more efficient.

[0018] 4. This manifold uses a compression fitting connection, which does not change the installation and usage habits, allowing users to use a manifold with a larger flow rate without feeling any difference. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] The structure of the high-flow-rate manifold provided in this embodiment is as follows: Figure 1-3 As shown, it includes a diversity main pipe 1 and one or more diversity branch pipes 2. The number of diversity branch pipes 2 can be set according to the actual situation.

[0026] Each manifold branch pipe 2 is equipped with a water distribution valve, which controls the opening and closing of the water passage within the manifold branch pipe 2. Each manifold branch pipe has a first through hole 3 on its side wall, which is in a two-step stepped shape. The larger diameter portion of the first through hole 3 communicates with the inner cavity of the manifold branch pipe 2. A limiting boss 4 is provided on the side wall of the manifold branch pipe 2, and a third through hole 5 is provided on the limiting boss 4. The third through hole 5 communicates with the smaller diameter portion of the first through hole 2, and the diameter of the third through hole 5 is the same as the smaller diameter portion of the first through hole 3. The limiting boss 4 and the manifold branch pipe 2 can be integrally formed, as can the first through hole 3 and the third through hole 5.

[0027] The water distribution valve includes a valve plate 6, a valve stem for driving the valve plate to rotate, a handle 23, and a limiting element. The valve plate 6 is disc-shaped, and a threaded hole 7 is provided on the side wall of the valve plate 6. The axis of the threaded hole 7 is located radially on the valve plate 6. The valve plate 6 is located inside the manifold 2, and the valve plate 6 can rotate within the manifold 2.

[0028] The valve stem includes an inner screw 8 and an outer sleeve 9, such as Figure 4 As shown, the outer sleeve 9 is in a two-stage stepped shape. The outer sleeve 9 passes through the third through hole 5 and the first through hole 3 in sequence. The outer sleeve 9 is clearance-fitted with the first through hole 3 and the third through hole 5, and the outer sleeve 9 is limited by the stepped surface of the first through hole 3. The valve plate 6 has a limiting groove 10 on its side wall, and the opening of the threaded hole 7 is located at the bottom of the limiting groove 10. A limiting protrusion 11 is provided on the end of the outer sleeve 9 facing the valve plate 6. The limiting protrusion 11 and the limiting groove 10 are connected and engaged. The outer sleeve 9 is limited by the engagement of the limiting protrusion 11 and the limiting groove 10 to prevent the outer sleeve 9 from slipping during rotation.

[0029] The handle 23 has a countersunk hole 12 and a slot 13 on opposite sides. The bottom of the countersunk hole 12 has a second through hole 14, and the countersunk hole 12 and the second through hole 14 are coaxial. The outer sleeve 9 has a tenon 15 at its end facing away from the valve plate 6. The outer sleeve 9 is fixedly connected to the handle 23 through the engagement of the tenon 15 and the slot 13. The handle 23 has a first limiting ring 16 on its side facing the manifold 2. The first limiting ring 16 is fitted onto the limiting boss 4 with a clearance fit. A limiting stop 17 is provided on the side wall of the limiting boss 4, and the first limiting ring 16 has a first notch 18 that engages with the limiting stop 17.

[0030] The inner screw 8 passes through the second through hole 14 and the outer sleeve 9 in sequence. The head of the inner screw 8 abuts against the limiting countersunk hole 12, and the tail of the inner screw 8 is threadedly connected to the threaded hole of the valve plate 6. The rotation angle of the handle 23 can be controlled by the cooperation of the first notch 18 and the limiting stop 17.

[0031] The limiting components include a second limiting ring 19 and a locking ring 20. The inner wall of the manifold 2 is stepped. The second limiting ring 19 is located inside the manifold 2, and its outer wall surface is in contact with the inner wall surface of the manifold 2. The end face of the second limiting ring 19 facing the main manifold 1 abuts against a stepped surface of the manifold 2. Two sealing rings are provided between the integrally formed structure of the outer sleeve 9, the limiting boss 4, and the manifold 2 to prevent water leakage at the connection of the outer sleeve 9. A second notch 21 is provided on the end of the second limiting ring 19 facing the main manifold 1. The second notch 21 abuts against the end of the outer sleeve 9 facing the valve plate 6. The valve plate 6 is rotatably connected to the second limiting ring 19.

[0032] The locking ring 20 is located inside the manifold 2. The locking ring 20 has external threads, and the inner wall of the manifold 2 has internal threads. The locking ring 20 is threadedly connected to the manifold 2. A sealing ring 24 is provided between the locking ring 20 and the manifold 2 to seal and prevent water leakage from the manifold. The locking ring 20 is in contact with the end of the second limiting ring 19 facing away from the manifold main 1. The end of the locking ring 20 facing away from the second limiting ring 19 has a flange 22, which is in contact with a stepped surface of the manifold 2.

[0033] In the initial position, one side wall of the first notch 18 abuts against the limiting block 17. At this time, the valve plate 6 is perpendicular to the axis of the manifold 2, and the side wall of the valve plate 6 is in circumferential contact with the inner wall of the manifold 2, thus closing the water distribution valve. Rotating the handle 23 90 degrees causes the other side wall of the first notch 18 to abut against the limiting block 17. Since the handle 23 is fixed as a whole with the inner screw 8, the outer sleeve 9, and the valve plate 6, the handle 23 drives the valve plate 6 to rotate. At this time, the valve plate 6 is parallel to the axis of the manifold 2, and the side wall of the valve plate 6 is in point contact with the inner wall of the manifold 2, thus opening the water distribution valve.
