Description

Technical Field

[0001] The utility model relates to the technical field of valve components, in particular to a valve component for flow regulation. Background Art

[0002] The valve assembly is a component composed of several thyristors and their triggering, protection, voltage balancing and valve inductors.

[0003] During the use of the existing valve assembly for flow regulation, water flows through the inner wall of the valve assembly, and the water flow is prone to carry impurities such as mud and sand, causing blockage on the inner wall of the valve assembly and reducing the flow rate. At the same time, when the device is connected to the water pipe, the connection is prone to be loose, resulting in water leakage and waste of water resources. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a valve assembly for flow regulation, which has the advantages of fluidity and sealing detection, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a valve assembly for flow regulation, comprising a valve body, an inner wall of the valve body being rotatably connected to a rotating rod, an outer wall of the rotating rod being fixedly mounted with a fan blade, a switch being provided on the top of the rotating rod, a frequency monitor being fixedly mounted on the top of the switch, an inner wall of the valve body being rotatably connected to a valve, a handle being mounted on the outer wall of the valve, a cylinder being fixedly mounted on the inner wall of the valve body, an alarm being fixedly mounted on the top of the cylinder, a support rod being fixedly mounted on the bottom of the support rod, a fixed block being fixedly mounted on the bottom of the fixed block, a spring being fixedly mounted on the bottom of the fixed block, a buffer block being fixedly mounted on one end of the spring, and a second tympanic membrane being fixedly mounted on the inner wall of the cylinder.

[0006] As a preferred technical solution of the utility model: the output end of the switch is electrically connected to the input end of the frequency monitor, the number of the fan blades is several, and the several fan blades are all located on the inner wall of the valve body.

[0007] As a preferred technical solution of the utility model: the diameter of the valve is the same as the diameter of the inner wall of the valve body, and the valve is located at the center of the inner wall of the valve body.

[0008] As a preferred technical solution of the utility model: the inner wall of one end of the valve body is threadedly connected to the outer wall of one end of the water pipe, and a controller is fixedly installed on the outer wall of the valve body.

[0009] As a preferred technical solution of the utility model: the second eardrum is elastic, the arc surface of the second eardrum is fixedly equipped with a magnet, and the magnet on the top of the second eardrum corresponds to the position of the magnet on the arc surface of the first eardrum, and the alarm, controller and magnet are electrically connected.

[0010] As a preferred technical solution of the utility model: a sealing ring is fixedly installed on the outer wall of the fan blade, and the diameter of the sealing ring is larger than the diameter of the rotating rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The valve assembly for flow regulation rotates the handle through external force, so that the handle drives the alarm to flip and the water flows. When water flows through the inner wall of the valve body, the rotating rod drives several blades to rotate under the action of the water flow, thereby contacting the switch, and the frequency monitor generates an electrical signal. Once the inner cavity of the valve body is blocked, the water flow speed slows down. At this time, within a certain period of time, the rotation speed of the rotating rod slows down, the number of times the switch is touched decreases, and the number of electrical signals received by the first eardrum decreases, so that it can be determined that the inner cavity of the valve body is blocked.

[0013] 2. The valve assembly for flow regulation has elasticity through the second eardrum, so that when water flows through the inside of the valve body and the sealing is intact, the impact force of the water flow can cause the second eardrum to drive the magnet to move upward and fit with the magnet at the bottom of the first eardrum. Through the electrical connection between the alarm, the controller and the magnet, an early warning can be given in time when a leak occurs at the connection between the valve body and the water pipe and the sealing is insufficient. The alarm can be used to warn the staff in time, so that the maintenance personnel can check and adjust the connection between the valve body and the water pipe in time.

[0022] In the above structure, a buffer block 16 is fixedly installed by one end of the spring 9, so that the stability of the first eardrum 10 is increased after installation, and the impact force between the second eardrum 12 and the first eardrum 10 is avoided to cause the position displacement of the first eardrum 10 when the second eardrum 12 is under pressure, which affects the subsequent detection effect of the internal sealing of the device.

[0023] In a preferred embodiment, the output end of the switch 17 is electrically connected to the input end of the frequency monitor 15 , the number of the fan blades 13 is multiple, and the multiple fan blades 13 are all located on the inner wall of the valve body 1 .

[0024] In the above structure, a rotating rod 6 is rotatably connected through the inner wall of the valve body 1. When water flows through the inner wall of the valve body 1, the rotating rod 6 drives a plurality of blades 13 to rotate under the action of the water flow, thereby contacting the switch 17, and the frequency monitor 15 generates an electrical signal. Once the inner cavity of the valve body 1 is blocked, the water flow speed slows down. At this time, within a certain period of time, the rotation speed of the rotating rod 6 slows down, and the number of times the switch 17 is touched is reduced, thereby reducing the number of electrical signals received by the first eardrum 10, and it can be determined that the inner cavity of the valve body 1 is blocked.

[0025] In a preferred embodiment, the diameter of the valve 14 is the same as the diameter of the inner wall of the valve body 1 , and the valve 14 is located at the center of the inner wall of the valve body 1 .

[0026] In the above structure, the handle 5 is rotated by external force, so that the handle 5 drives the valve 14 to rotate, and the valve 14 is rotated on the inner wall of the valve body 1 to achieve a sealing effect on the inner wall, so that the valve 14 plays a cut-off role, cuts off or closes the flow of fluid, and ensures that the fluid will not flow without permission, thereby ensuring the safety and stability of the system.

[0027] In a preferred embodiment: the inner wall of one end of the valve body 1 is threadedly connected to the outer wall of one end of the water pipe 2, and a controller is fixedly mounted on the outer wall of the valve body 1.

[0028] In the above structure, the water pipe 2 is threadedly connected to the valve body 1, so that the water pipe 2 and the inner wall of the valve body 1 can be quickly installed to achieve water flow.

[0029] In a preferred embodiment: the second eardrum 12 is elastic, the arc surface of the second eardrum 12 is fixedly equipped with a magnet 11, and the magnet 11 on the top of the second eardrum 12 corresponds to the position of the magnet 11 on the arc surface of the first eardrum 10, and the alarm 4 and the controller and the magnet 11 are electrically connected.

[0030] In the above structure, the second eardrum 12 has elasticity, so that when water flows through the inside of the valve body 1 and the sealing is intact, the impact force of the water flow can cause the second eardrum 12 to drive the magnet 11 to move upward and fit with the magnet 11 at the bottom of the first eardrum 10. Through the electrical connection between the alarm 4, the controller and the magnet 11, when leakage occurs at the connection between the valve body 1 and the water pipe 2 and the sealing is insufficient, an early warning can be given in time, and the alarm 4 can be used to warn the staff in time, so that the maintenance personnel can check the connection between the valve body 1 and the water pipe 2 in time, thereby improving the practicality of the device.

[0031] In a preferred embodiment, a sealing ring is fixedly mounted on the outer wall of the fan blade 13 , and the diameter of the sealing ring is greater than the diameter of the rotating rod 6 .

[0032] In the above structure, the diameter of the sealing ring is larger than the diameter of the rotating rod 6, so that when the rotating rod 6 rotates on the inner wall of the valve body 1, the sealing ring is used to seal the connection between the rotating rod 6 and the valve body 1 to prevent water from overflowing.

[0033] Working principle: The water pipe 2 is connected to the inner wall of the valve body 1 so that water flows through the inner wall of the valve body 1. The handle 5 is turned by external force so that the handle 5 drives the alarm 4 to turn over and the water flows. When water flows through the inner wall of the valve body 1, the rotating rod 6 drives a plurality of blades 13 to rotate under the action of the water flow, thereby contacting the switch 17. The frequency monitor 15 generates an electrical signal. Once the inner cavity of the valve body 1 is blocked, the water flow speed slows down. At this time, within a certain period of time, the rotating rod 6 rotates slower, and the number of times the switch 17 is touched is reduced, thereby reducing the number of electrical signals received by the first tympanic membrane 10. It can be determined that the inner cavity of the valve body 1 is blocked. When the valve body 1 is blocked, the water flow speed slows down. When the connection between the valve body 1 and the water pipe 2 is not tight and leakage occurs, the second eardrum 12 has elasticity, so that water flows through the inside of the valve body 1. When the sealing is intact, the impact force of the water flow can cause the second eardrum 12 to drive the magnet 11 to move upward and fit with the magnet 11 at the bottom of the first eardrum 10. Through the electrical connection between the alarm 4, the controller and the magnet 11, an early warning can be given in time when leakage occurs at the connection between the valve body 1 and the water pipe 2 and the sealing is insufficient. The alarm 4 can be used to warn the staff in time, so that the maintenance personnel can check the connection between the valve body 1 and the water pipe 2 in time, avoid wasting a lot of water resources, and improve the practicality of the device.
