Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, in particular to a combined hydraulic valve core. Background Art

[0002] A hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of a pressure regulating valve. It is usually used in combination with an electromagnetic pressure regulating valve and can be used to remotely control the on / off of oil, gas, and water pipeline systems in a hydropower station. It is often used for clamping, controlling, lubricating, and other oil circuits. There are direct-acting and pilot-operated types, and the pilot-operated type is more commonly used.

[0003] In actual application of existing hydraulic valve cores, since there are often foreign particles in the hydraulic pipeline, when these foreign particles remain between the valve core and the valve sleeve of the valve core mechanism, they will affect the sealing of the hydraulic valve, causing the hydraulic valve to be unable to be used normally. Therefore, we propose a combined hydraulic valve core. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] A combined hydraulic valve core provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0022] Combination Figure 1-3 As shown, the utility model provides a combined hydraulic valve core, including: a valve body mechanism 100 and a valve core mechanism 200; wherein the valve body mechanism 100 includes a valve sleeve 110 and a liquid inlet 120 and a liquid outlet 130 opened on the valve sleeve 110.

[0023] The valve core mechanism 200 is arranged in the valve sleeve 110, and the valve core mechanism 200 includes a core body 210 assembled in the valve sleeve 110, a spring 220 arranged in the core body 210, a baffle 230 connected to the end of the spring 220, a limit block 240 fixed in the valve sleeve 110 to limit the baffle 230, a through groove 250 opened on the limit block 240, a rotating plate 260 installed on the outer side of the baffle 230, a servo motor 270 assembled in the valve sleeve 110 and against the side of the rotating plate 260, and a servo motor 270 connected to the valve sleeve 110. The core body 210 and the servo motor 270 are connected through the connecting rod 280 of the through groove 250 and the discharge groove 290 opened at the front end of the core body 210. Through the valve core mechanism 200, after the core body 210 stops working and fits with the valve sleeve 110, the servo motor 270 can be used to drive the core body 210 to rotate, so that the foreign particles remaining in the sealing part between the valve sleeve 110 and the core body 210 enter the discharge groove 290, so as to ensure the sealing. The foreign particles will naturally fall from the discharge groove 291 after the operation stops, without manual cleaning, and effectively ensure the sealing of the hydraulic valve.

[0024] Specifically, the core body 210 is provided with a pressure equalizing groove 211 to ensure the stability of the material in and out, thereby making the core body 210 evenly stressed and reducing wear.

[0025] Furthermore, the core 210 is provided with a fan blade 212 located in the middle of the liquid inlet 120, and the end of the fan blade 212 is connected to a generator 213 embedded in the core 210. The fan blade 212 and the generator 213 can generate electricity by utilizing the materials flowing in and out, and then supply electricity to the baffle 230, which has high practicality.

[0026] On the other hand, the through grooves 250 are fan-shaped guide grooves symmetrically distributed on the baffle 230, which can enable the connecting rod 280 to perform a half-circle motion, so that the foreign particles can be cleaned by rotation.

[0027] It should be noted that the blanking chutes 290 are evenly and symmetrically distributed on the core 210 in at least two groups, and at least two groups are more than two groups, so that all the impurity particles can be cleaned up by rotating within a certain range.

[0028] Furthermore, a discharge trough 291 is provided on the inner side of the discharge trough 290 , and an opening is provided on the outer end of the discharge trough 291 , so as to facilitate the natural separation of foreign particles without manual cleaning.

[0029] The working principle and use process of the utility model are as follows: first, after the core body 210 stops working and fits with the valve sleeve 110, the servo motor 270 is used to drive the core body 210 to rotate, so that the impurity particles remaining in the sealing part between the valve sleeve 110 and the core body 210 enter the discharge groove 290, and the impurity particles will naturally fall from the discharge groove 291 after the operation stops.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
