Description

Technical Field

[0001] The invention belongs to the technical field of flow valve controllers, and in particular relates to a flow valve reset regulator for slowing down the resetting speed of a flow valve. Background Art

[0002] Angle valve, also known as angle stop valve or flow valve, has a simple structure and is one of the commonly used valves in life and industry. Angle valve is often used to transfer internal and external water outlets, and the amount of water transferred is adjusted by switching or closing the transfer to allow water to flow.

[0003] At present, angle valves or flow valves are used in flushing systems. The opening and closing of the angle valves or flow valves are driven by external force. When the external force is reset, the angle valves or flow valves will follow and close. When there are some scenes that require the angle valves or flow valves to close slowly, the existing angle valves or flow valves are no longer suitable for the scenes. Therefore, it is currently necessary to design a controller that is used in conjunction with the angle valve (flow valve) and is used to adjust the reset speed of the angle valve (flow valve). Summary of the invention

[0004] The object of the present invention is to provide a flow valve reset regulator which is used in conjunction with a flow valve and is used to adjust the reset speed of the flow valve.

[0005] The technical solution adopted by the present invention is: a flow valve reset regulator, including a mounting ring and a rotating disk for linking with the flow valve shaft, the rotating disk is rotatably placed in the mounting ring and is connected to a reset component that can drive the rotating disk to rotate and reset, and a friction component for adjusting the reset speed of the rotating disk is provided between the mounting ring and the rotating disk.

[0006] The friction assembly moves radially and is circumferentially limited on the mounting ring.

[0007] The inner ring of the installation ring is radially formed with a limiting groove, and the friction component is assembled in the limiting groove.

[0008] The friction assembly includes an adjusting bolt, a radial motion part and a friction part arranged from outside to inside. The adjusting bolt is threaded on the outside of the mounting ring. The inner end of the adjusting bolt radially penetrates the mounting ring body and the limiting groove and then abuts against the radial motion part, and the friction part abuts against the rotating disk.

[0009] The contact surface between the friction part and the rotating disk is in an arc shape matching the outer contour of the rotating disk.

[0010] The outer diameter of the body at the junction of the rotating disk and the friction part is greater than the outer diameter of the body at other positions of the rotating disk.

[0011] The reset component is a clockwork spring.

[0012] An assembly ring is further provided between the installation ring and the rotating disk. The assembly ring is axially provided with a counterbore, the rotating disk is placed in the counterbore, and a shaft hole for the rotation shaft of the flow valve to pass through is provided at the counterbore. The assembly ring is radially provided with a notch groove for the radial passing of the friction assembly.

[0013] There are two groups of the friction assemblies, which are symmetrically arranged on the installation ring.

[0014] A driving rod that rotates circumferentially synchronously with the rotating disk is connected to the outside of the rotating disk.

[0015] The technical effects of the present invention are as follows: 1. The rotating disk of the present invention is linked with the rotation shaft of the flow valve. During the reset process, the rotating disk is affected by the frictional force, which prolongs the reset time of the flow valve and is more suitable for occasions where the closing time of the flow valve needs to be extended; for example, when applied to a toilet, the water seal amount can be increased. 2. The friction assembly can achieve radial movement, and the frictional force can be adjusted according to needs, thereby adjusting the closing time of the flow valve, with a wider adaptability. 3. The outer diameter of the body at the joint of the rotating disk and the friction part is slightly larger, which can achieve the effect of fast flushing and slow water stop.

[0016] Preferably, the friction assembly moves radially and is circumferentially limited on the installation ring. The radial extrusion friction setting has a better friction effect than the axial extrusion friction setting, and at the same time, the processing and assembly are more convenient.

[0017] Preferably, a limiting groove is radially formed in the inner ring of the installation ring, and the friction assembly is assembled in the limiting groove, which is convenient for processing.

[0018] Preferably, the friction assembly includes an adjusting bolt, a radially moving part and a friction part arranged from outside to inside. The adjusting bolt is screwed outside the installation ring, and the inner end of the adjusting bolt radially penetrates the installation ring body and the limiting groove and abuts against the radially moving part, and the friction part abuts against the rotating disk. By rotating the adjusting bolt from the outside, the change of the frictional force can be realized, which is convenient for operation. At the same time, when the friction part is worn, it is also convenient to replace the friction part.

[0019] Preferably, the contact surface between the friction part and the rotating disk is an arc shape matching the outer contour of the rotating disk. The contact surface is an arc shape, the area of the friction surface is larger, and the rotation speed of the rotating disk is more uniform during the reset process.

[0020] As an improvement, the outer diameter of the body at the joint of the rotating disk and the friction part is larger than that of the body at other positions of the rotating disk. When the flow valve is opened, that is, when an external force drives the rotating disk or the rotating shaft of the flow valve, after the part with a larger outer diameter of the rotating disk separates from the friction part, the frictional force between the part with a smaller outer diameter of the rotating disk and the friction part becomes smaller, and at this time, the resistance generated by the rotating disk becomes smaller. When the external force is cancelled, under the action of the return spring, the flow valve starts to reset and close. In the first half of the rotation of the rotating disk, the resistance from the friction part is small and the speed is relatively fast; in the second half of the rotation of the rotating disk, the part with a larger outer diameter of the rotating disk comes into play, and the resistance from the friction part is large, and the reset speed of the rotating disk is slow.

[0021] Preferably, the reset component is a clockwork spring. This type of spring generates torsion in its own plane and has better stability.

[0022] As an improvement, an assembly ring is further provided between the mounting ring and the rotating disk. The assembly ring is axially provided with a counterbore, the rotating disk is placed in the counterbore, and a shaft hole for the rotating shaft of the flow valve to pass through is provided at the counterbore. The assembly ring is radially provided with a notch groove for the radial passage of the friction assembly. The setting of the assembly ring facilitates the installation of the return spring, as well as the connection and installation between the rotating shaft of the flow valve and the rotating disk.

[0023] Preferably, there are two groups of the friction assemblies and they are symmetrically arranged on the mounting ring. The frictional force on the rotating disk is more balanced.

[0024] As an improvement, a driving rod that rotates circumferentially synchronously with the rotating disk is connected to the outside of the rotating disk. It is convenient to apply an external force to the rotating disk to control the opening of the flow valve. Description of the Drawings

DETAILED DESCRIPTION

[0038] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0039] like Figures 1 - 12 As shown in the following: An embodiment, a flow valve reset regulator comprises a mounting ring 11 and a rotating disk 12 for linkage with the rotating shaft of the flow valve, the rotating disk 12 is rotatably placed in the mounting ring 11 and is connected to a reset component 13 capable of driving the rotating disk 12 to rotate and reset; the outer contour of the rotating disk 12 is circular, a mounting hole is provided in the mounting ring 11, and the rotating disk 12 is installed in the mounting hole; a friction component 14 for adjusting the reset speed of the rotating disk 12 is provided between the mounting ring 11 and the rotating disk 12. In the embodiment, the friction component 14 moves radially and is circumferentially limited on the mounting ring 11. It means that the friction component 14 can move radially, but is circumferentially limited. Specifically, a limiting groove 11.1 is radially formed on the inner ring of the mounting ring 11, and the friction component 14 is assembled in the limiting groove 11.1. In the present embodiment, the limiting groove 11.1 directly axially penetrates the two end faces of the mounting ring 11, and of course, it can also only penetrate the end face of the mounting ring 11 body on the same side as the outer end face of the rotating disk 12. That is, Figure 5 shown.

[0040] In this embodiment, combined with Figure 6 , Figure 7As shown, the friction assembly 14 includes an adjusting bolt 14.1, a radially moving part 14.2, and a friction part 14.3 arranged from outside to inside. The adjusting bolt 14.1 is screwed outside the mounting ring 11. The inner end of the adjusting bolt 14.1 radially penetrates the body of the mounting ring 11 and the limiting groove 11.1 and abuts against the radially moving part 14.2. The radially moving part 14.2 is provided with a pit in contact with the adjusting bolt 14.1; the friction part 14.3 abuts against the rotating disk 12. In the embodiment, the radially moving part 14.2 and the friction part 14.3 are integrally formed. Of course, the radially moving part 14.2 and the friction part 14.3 can also be integrally formed. The purpose of integrally forming in this embodiment is to facilitate the replacement of the friction part 14.3. The friction part 14.3 is made of rubber or silica gel or other similar materials. In this embodiment, the friction part 14.3 is made of silica gel.

[0041] In this embodiment, in order to improve the reset stability of the rotating disk 12, the contact surface between the friction part 14.3 and the rotating disk 12 is an arc shape matching the outer contour shape of the rotating disk 12. At the same time, the friction assemblies 14 are two groups and are symmetrically arranged on the mounting ring 11.

[0042] In this embodiment, the outer diameter of the body at the joint of the rotating disk 12 and the friction part 14.3 is larger than the outer diameter of the body at other positions of the rotating disk 12. When the flow valve is opened, that is, when an external force drives the rotating disk 12 or the flow valve rotating shaft, after the part with a larger outer diameter of the rotating disk 12 is separated from the friction part 14.3, the friction force between the part with a smaller outer diameter of the rotating disk 12 and the friction part 14.3 becomes smaller, and at this time the resistance generated by the rotating disk 12 becomes smaller. When the external force is cancelled, under the action of the return spring, the flow valve starts to reset and close. In the first half of the rotation of the rotating disk 12, the resistance from the friction part 14.3 is small and the speed is relatively fast; in the second half of the rotation of the rotating disk 12, the part with a larger outer diameter of the rotating disk 12 comes into play, and the resistance from the friction part 14.3 is large, and the reset speed of the rotating disk 12 is slow. After applying the present invention to a toilet, the effect of fast flushing and slow water stopping can be achieved.

[0043] In the embodiment, the reset assembly 13 is a clockwork spring. One end of the clockwork spring is connected to the rotating shaft of the rotating disk 12 (which is also the flow valve rotating shaft), and the other end is connected to the inner wall of the assembly ring 15. The rotating disk 12 is located outside the reset assembly 13; in another embodiment, it can also be connected to the inner wall of the mounting ring 11. When the clockwork spring is connected to the inner wall of the assembly ring 15, the clockwork spring is located inside the assembly ring 15. The reset assembly 13 can also be a torsion spring, or other springs that can generate a reset force.

[0044] In another embodiment, an assembly ring 15 is further provided between the mounting ring 11 and the rotating disk 12. The assembly ring 15 is axially provided with a counterbore 15.1. The rotating disk 12 is placed in the counterbore 15.1. An axial hole 15.2 facilitating the flow valve rotating shaft to pass through is provided at the counterbore 15.1. The assembly ring 15 is radially provided with a notch groove 15.3 for the friction assembly 14 to radially pass through.

[0045] In another embodiment, a driving rod 16 that rotates circumferentially synchronously with the rotating disk 12 is connected to the outside of the rotating disk 12. It is convenient to apply an external force to the rotating disk 12 to control the opening of the flow valve.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
