Description

Technical Field

[0001] The utility model relates to the technical field of valve structures, in particular to a manifold valve core module. Background Art

[0002] The manifold is the main controller for the water inlet and outlet of floor heating. Because there are many branch pipes on the manifold and the manifold, corresponding valves are installed on each branch pipe to ensure independent opening and closing control.

[0003] Today's valves are basically traditional structures, with opening and closing control achieved through the movement of the valve core. However, water hammer effect is prone to occur during the opening and closing process of the valve, which not only produces loud noise but also directly damages the pipeline, and in severe cases may even cause direct rupture. In order to avoid such problems, a manifold valve core module is proposed. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a manifold valve core module, including a valve body, an inner wall of the valve body is fixedly connected to a partition, both side walls of the valve body opposite to the partition are rotatably connected to a sealing plate through a torsion spring, and the two sealing plates are opened and rotated in opposite directions, the top side wall of the valve body is fixedly connected to a riser, the end of the riser away from the valve body is fixedly connected to an outer ball, and the bottom side wall of the valve body is fixedly connected to a protrusion.

[0005] As a preferred technical solution of the present invention, an inner ball is set up inside the outer ball. The inner ball is fixedly connected to the top of the vertical pipe through the bottom side wall and the interior is communicated. Two overflow holes are opened through the side wall of the top of the inner ball, and a water inlet hole is opened through the side wall of the vertical pipe close to the inner ball and located inside the outer ball.

[0006] As an optimal technical solution of the present invention, the side wall of the partition opposite to the protrusion is an arc-shaped structure, a screw is rotatably connected through the protrusion, one end of the screw is rotatably connected to the bottom side wall of the partition, and a valve plate is threadedly connected to the screw.

[0007] As an optimal technical solution of the present invention, an arc-shaped groove is provided on the side wall of the protrusion near the top, and a float is provided in the arc-shaped groove. The bottom edge of the partition is connected to a vertical plate by a torsion spring, and the end of the vertical plate away from the partition is fixedly connected to the side wall of the float.

[0008] As a preferred technical solution of the present invention, one end of the screw passes through the valve body and is fixedly connected to a gear, one side of the gear is meshed with a rack, one end of the rack is fixedly connected to a miniature telescopic rod, one end of the miniature telescopic rod is detachably connected to a fixing plate, and the fixing plate is fixedly connected to the bottom side wall of the valve body.

[0009] The utility model has the following advantages: the valve body is divided into two areas by a partition. When the water hammer effect occurs, the sealing plate will open under the drive of pressure. At this time, the water rushing from the pool will enter the partition above the partition, and the water flow is forced into the partition. Because the upper part of the partition has an arc-shaped structure, the internal space is large. The water flow in it can effectively alleviate the pressure generated by the water hammer, thereby reducing the negative impact of the water hammer, thereby increasing the service life of the equipment and pipelines and improving their practical performance.

[0010] By driving the valve plate up and down through the screw, the water flow rate can be controlled to ensure that the heating water flows evenly and stably in the pipe, avoiding the problem of sudden changes in temperature. The vertical plate and float can also realize the check function to prevent backflow from affecting the normal water transportation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to Figure 1-3 The utility model discloses a manifold valve core module, comprising a valve body 1, the inner wall of which is fixedly connected to a partition 11, and the side walls on both sides of the valve body 1 opposite to the partition 11 are rotatably connected to a sealing plate 17 via a torsion spring, and the two sealing plates 17 are opened and rotated in opposite directions, the top side wall of the valve body 1 is fixedly connected to a riser 2, the end of the riser 2 away from the valve body 1 is fixedly connected to an outer ball 3, and the bottom side wall of the valve body 1 is fixedly connected to a protrusion 12;

[0017] An inner ball 8 is set up inside the outer ball 3. The inner ball 8 is fixedly connected to the top of the vertical pipe 2 through the bottom side wall and is internally communicated. Two overflow holes 9 are opened through the side wall of the top of the inner ball 8, and a water inlet hole 10 is opened through the side wall of the vertical pipe 2 close to the inner ball 8 and located inside the outer ball 3.

[0018] The technical effect of this solution is: when water hammer occurs, the corresponding sealing plate 17 will be opened under the drive of pressure, and the water will flow into the space above the partition 11, thereby increasing the formation of water flow, thereby alleviating the pressure and impact force caused by the water hammer. At the same time, water will enter the inner ball 8 through the riser 2. When the water flow is too large, it will enter the space between the inner ball 8 and the outer ball 3 from the overflow hole 9 and finally flow back into the valve body 1 through the water inlet hole 10, forming a circulating flow function, which can effectively avoid the negative impact caused by water hammer. When a negative water hammer effect occurs, the corresponding sealing plate 17 will also be opened under the drive of pressure, and the water reserved in the area above the partition 11 will enter the pipeline, thereby filling the space in the pipeline, thereby eliminating the impact of negative water hammer and improving the service life of equipment and pipelines.

[0019] The side wall opposite to the partition 11 and the protrusion 12 is an arc-shaped structure. A screw 13 is rotatably connected to the protrusion 12. One end of the screw 13 is rotatably connected to the bottom side wall of the partition 11. A valve plate 14 is threadedly connected to the screw 13. An arc groove is provided on the side wall of the protrusion 12 near the top, and a float 16 is provided in the arc groove. The bottom edge of the partition 11 is rotatably connected to a vertical plate 15 through a torsion spring. The end of the vertical plate 15 away from the partition 11 is fixedly connected to the side wall of the float 16. One end of the screw 13 passes through the valve body 1 and is fixedly connected to a gear 5. One side of the gear 5 is meshed with a rack 6. One end of the rack 6 is fixedly connected to a micro telescopic rod 7. One end of the micro telescopic rod 7 is detachably connected to a fixed plate 4. The fixed plate 4 is fixedly connected to the bottom side wall of the valve body 1.

[0020] The technical effect of this solution is: the gear 5 is rotated as needed to drive the valve plate 14 to rise and fall through the threaded connection, thereby controlling the distance between the valve plate 14 and the partition 11, so as to control the amount of flow, and can also be flexibly adjusted according to the demand ratio. When water flows through the distance, the float 16 will be squeezed open by the water pressure. When backflow occurs, the float 16 will be moved toward the direction of the protrusion 12, and finally fit on the side wall of the protrusion 12 to achieve the sealing function and avoid backflow.

[0021] Specifically, when the present invention is used, the pipeline is connected to the valve body 1, the micro telescopic rod 7 is started to control the movement of the rack 6, the gear 5 is driven to rotate through the meshing connection, and the valve plate 14 is driven to rise and fall through the threaded connection, so as to adjust the distance between the valve plate 14 and the partition 11, thereby realizing the function of adjusting the flow rate according to demand, and the backflow function can be realized through the vertical plate 15 and the float 16. When the water hammer effect occurs, the corresponding sealing plate 17 will be opened to introduce water flow into the area above the partition 11, increase the formation of water flow or inject water into the pipeline, so as to alleviate the impact of water hammer on equipment and pipelines, and improve the service life of equipment and pipelines.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
