Description

Technical Field

[0001] This utility model relates to steering wheels, and more particularly to a steering wheel resistant to dirt and clogging. Background Technology

[0002] The steering valve's actuators (magnetic rotor and steering wheel) are mainly connected together by a coupling. However, the coupling method has a drawback: running forward and backward at a frequency of 500 to 900 times per minute for a long time, and due to the large mass of both components, the moment of inertia is also large. This will further cause wear on the coupling between the magnetic rotor and the steering wheel, reducing the service life of the actuators and causing some trouble for maintenance.

[0003] Furthermore, the water used in current water-jet looms is circulating water. This circulating water, if left untreated for a long time, is prone to harboring short weft fibers, particulate matter, and sticky dirt. Additionally, because the water in the area where the magnetic rotor is located is almost stagnant, dirt can easily accumulate slowly within the housing cavity. If this dirt is not cleaned in time, it can affect the operating frequency of the steering valve or cause the steering wheel to fail to reverse properly. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a steering wheel that is resistant to dirt and clogging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steering wheel resistant to dirt and clogging, characterized in that: it includes a central shaft hole, a guide ring groove, a first magnetic groove, and a second magnetic groove, wherein the first magnetic groove and the second magnetic groove are located on both sides of the guide ring groove and are symmetrically positioned; the central shaft hole is located at the center of the guide ring groove; a limiting groove and a steering flow channel are provided below the first magnetic groove and the second magnetic groove; the steering flow channel includes a first steering flow channel and a second steering flow channel; a first water inlet path and a second water inlet path are respectively provided between the guide ring groove and the first steering flow channel and the second steering flow channel.

[0006] In the aforementioned anti-clogging steering wheel, a first limiting point and a second limiting point are provided on both sides of the limiting groove.

[0007] In the aforementioned anti-clogging steering wheel, a second anti-pressure groove is provided between the first limiting point and the second steering flow channel, and a first anti-pressure groove is provided between the second limiting point and the first steering flow channel.

[0008] In the aforementioned anti-clogging steering wheel, the end of the first anti-pressure groove forms a first sealing ring surface, and the end of the second anti-pressure groove forms a second sealing ring surface.

[0009] In the aforementioned anti-clogging steering wheel, the magnetic field distribution line formed by the first magnetic groove, the central shaft hole, and the second magnetic groove coincides with or is perpendicular to the limiting line formed by the limiting groove and the central shaft hole.

[0010] In the aforementioned anti-clogging steering wheel, the first steering flow channel and the second steering flow channel are symmetrically positioned and are either interconnected or independently spaced.

[0011] In the aforementioned anti-clogging steering wheel, a first drain valve and a second drain valve, respectively connected to the first and second steering channels, are provided above the first and second steering channels.

[0012] Alternatively, a drain hole connected to the flow guide ring groove may be provided on the outer wall of the flow guide ring groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention achieves an integrated design of the magnet and steering wheel by embedding magnets (or magnetic tiles) into the first and second magnetic grooves on the steering wheel. This reduces the overall weight of the actuator, thereby reducing the moment of inertia and extending the service life of the actuator. Furthermore, it eliminates wear between actuator components, further improving their lifespan. Simultaneously, it also reduces manufacturing and installation costs.

[0015] This invention features a first drain valve and a second drain valve on the steering wheel. High-pressure water flow drives the water flow around the steering wheel, allowing dirt around the steering wheel to directly enter the drain hole, thus preventing dirt from accumulating inside the steering valve.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments. The following detailed description of the present invention is for illustrative purposes only and is not intended to limit the present invention or its applications or uses.

[0023] Reference Figures 1 to 4 As shown, a steering wheel resistant to dirt and clogging includes a central shaft hole 301, a guide ring groove 309, a first magnetic groove 302, and a second magnetic groove 303. The first magnetic groove 302 and the second magnetic groove 303 are located on both sides of the guide ring groove 309 and are symmetrically positioned. The first magnetic groove 302 and the second magnetic groove 303 are used to place and fix magnets or magnetic tiles (equivalent to magnetic rotors in the prior art).

[0024] By embedding magnets (or magnetic tiles) into the first magnetic groove 302 and the second magnetic groove 303 on the steering wheel, an integrated design of the magnets and the steering wheel is achieved. This reduces the overall weight of the actuator components, thereby reducing the moment of inertia and increasing the service life of the actuator components. Furthermore, it eliminates wear between the actuator components, further extending their service life. At the same time, it also reduces manufacturing and installation costs.

[0025] Furthermore, if neodymium iron boron magnets are used, high coercivity models should be preferred due to their need to withstand high-frequency motion conditions over long periods. After installation and fixing, glue is applied to the first magnetic groove 302 and the second magnetic groove 303 for sealing purposes to prevent the neodymium iron boron from rusting.

[0026] If it is a ferrite magnet, it is fixed in the magnetic groove by interference fit, and can also be reinforced by potting.

[0027] The central shaft hole 301 is located at the center of the guide ring groove 309; the purpose is to make the steering wheel 3 rotate around the central shaft and prevent positional deviation.

[0028] Below the first magnetic groove 302 and the second magnetic groove 303, there is a limiting groove 306 and a turning flow channel;

[0029] The turning flow channel includes a first turning flow channel 3071 and a second turning flow channel 3072, and the first turning flow channel 3071 and the second turning flow channel 3072 are symmetrically positioned.

[0030] The first turning channel 3071 and the second turning channel 3072 can be either spaced apart and independent or connected to each other.

[0031] In order to quickly guide the water in the guide ring groove 309 into the corresponding water outlet, the guide ring groove 309 is provided with a first water inlet path 3051 corresponding to the first turning channel 3071 and a second water inlet path 3052 corresponding to the second turning channel 3072.

[0032] In order to ensure that the steering wheel 3 is in the correct position, a first limiting point 3061 and a second limiting point 3062 are provided on both sides of the limiting groove 306, and the first limiting point 3061 and the second limiting point 3062 are symmetrical.

[0033] To improve the response frequency of the steering valve, the smaller the limiting angle formed by the limiting groove 306, the better. The smaller the angle, the shorter the travel distance. However, based on practical considerations, the limiting angle of this invention is generally set between 25° and 120°.

[0034] At the same time, the sector angle of the first magnetic slot 302 and the second magnetic slot 303 is greater than or equal to the limiting angle.

[0035] To facilitate water flow within the diverting valve in this embodiment, a first drain valve 3041 and a second drain valve 3042, respectively connected to the first diverting flow channel 3071 and the second diverting flow channel 3072, are provided. The working principle is that when water flows through the first drain valve 3041 or the second drain valve 3042, the increased flow velocity leads to a decrease in local pressure (Bernoulli's principle), creating a pressure difference between the inlet and outlet. This pressure difference drives water circulation, carrying away the dirt deposited within the diverting valve and ultimately discharging it from the corresponding outlet.

[0036] Alternatively, a drain hole communicating with the guide ring groove 309 can be provided on the outer wall of the guide ring groove 309. In this case, the main function of the drain hole in the diverting valve is to generate a pressure difference through the high-speed water flow inside the guide ring groove 309, thereby driving the water flow outside the guide ring groove 309 to discharge dirt to the outside of the diverting valve.

[0037] To improve the water pressure resistance of the steering wheel 3 (especially for large-diameter and high-water-pressure conditions), a second pressure-resistant groove 3082 is provided between the first limiting point 3061 and the second steering flow channel 3072, and a first pressure-resistant groove 3081 is provided between the second limiting point 3062 and the first steering flow channel 3071. The first pressure-resistant groove 3081 and the second pressure-resistant groove 3082 are symmetrically positioned and identical in size. To suppress creep deformation of the steering wheel 3 under long-term pressure, a support disc with a central balance hole is embedded between the first pressure-resistant groove 3081 and the second pressure-resistant groove 3082. The central balance hole prevents the support disc from sliding down due to pressure differential.

[0038] The end of the first pressure-resistant groove 3081 forms the first sealing ring surface 3101, and the end of the second pressure-resistant groove 3082 forms the second sealing ring surface 3102. The first sealing ring surface 3101 and the second sealing ring surface 3102 are coplanar (flushly distributed), and can be either independently spaced or physically connected. To reduce the vacuum area between the sealing surfaces and improve the response frequency of the steering valve, this invention preferentially adopts a spaced distribution scheme for the sealing ring surfaces.

[0039] In order for the steering wheel to rotate, the magnetic field distribution line formed by the first magnetic groove 302, the central shaft hole 301, and the second magnetic groove 303 coincides with or is perpendicular to the limiting line formed by the limiting groove 306 and the central shaft hole 301.

[0040] The above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made based on the substance of the content of this utility model should be covered within the scope of protection of this utility model.
