Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, in particular to an automatically docking hydraulic valve. 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 the oil, gas, and water pipeline systems of 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] When liquid materials such as oil are passed into the existing hydraulic valve, some of the viscous liquid may be adsorbed on the inner wall of the hydraulic valve and the surface of the valve core. If it is not cleaned in time, the hydraulic valve may contaminate the medium and reduce the cleanliness of the medium when other media are passed into it. If the staff wants to clean it, they need to disassemble the hydraulic valve, which is very inconvenient. Utility Model Content

[0019] 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.

[0020] An automatic docking hydraulic valve provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0021] Combination Figure 1-2As shown, the utility model provides an automatic docking hydraulic valve, comprising: a valve body assembly 100 and a valve core assembly 200; wherein the valve body assembly 100 comprises an outer sleeve 110 and an inlet 120 and an outlet 130 opened on the outer sleeve 110.

[0022] The valve core assembly 200 is arranged in the outer sleeve 110, and the valve core assembly 200 includes a core body 210 assembled in the outer sleeve 110, a spring 220 arranged in the core body 210, a cover plate 230 connected to the spring 220 and installed on the outer sleeve 110, a hydraulic rod 240 embedded in the core body 210 and connected to the cover plate 230, a valve head 250 arranged at the front end of the core body 210, a rotator 260 embedded in the valve head 250, an electric telescopic rod 270 fixed to the driving part of the rotator 260, a telescopic sleeve rod 280 fixed to the driving end of the electric telescopic rod 270, a spring 281 arranged in the telescopic sleeve rod 280, and a scraper fixed to the end of the telescopic sleeve rod 280. The plate 282, the vibrator 290 arranged on one side of the rotator 260, and the vibrating rod 291 arranged on the side of the valve head 250 and electrically connected to the vibrator 290, through the valve core assembly 200, can use the hydraulic rod 240 to control the core body 210 to move forward and backward, and at the same time, the electric telescopic rod 270 drives the telescopic sleeve rod 280 to extend outward. At this time, the scraper 282 extends outward under the action of the spring 281. After the scraper 282 contacts the inner wall of the outer sleeve 110, the rotator 260 drives the electric telescopic rod 270 and the scraper 282 to rotate, thereby cleaning the inner wall of the outer sleeve 110, and then the vibrator 290 controls the vibrating rod 291 to vibrate, so that the residue on the valve head 250 falls off, thereby achieving comprehensive cleaning without the need for manual auxiliary operation, and having high practicality.

[0023] Specifically, a generator 271 connected to the telescopic sleeve 280 is fixed to the driving end of the electric telescopic rod 270. The telescopic sleeve 280 can be extended outward when the material is flowing, and the scraper 282 can be rotated under the flow to generate electricity for use by other power-consuming structures.

[0024] Furthermore, the telescopic sleeve rods 280 are provided with two groups which are symmetrically distributed, so as to improve the cleaning efficiency.

[0025] On the other hand, the valve head 250 is made of a hard rubber block, which can transmit the vibration under the vibration of the vibration rod 291, so that the residual vibration on the surface of the core body 210 falls off.

[0026] It should be noted that a stainless steel protective layer is provided on the outer side of the valve head 250, which can protect the core body 210, ensure the sealing between the valve head 250 and the outer sleeve 110, and does not affect the vibration cleaning.

[0027] Furthermore, the vibration rods 291 are evenly distributed on the valve head 250 in multiple groups, and multiple groups are at least two groups. The more groups there are, the stronger the vibration is and the better the cleaning efficiency is.

[0028] The working principle and use process of the utility model are as follows: first, the hydraulic rod 240 controls the core body 210 to move forward and backward, and at the same time, the electric telescopic rod 270 drives the telescopic sleeve rod 280 to extend outward. At this time, the scraper 282 extends outward under the action of the spring 281. After the scraper 282 contacts the inner wall of the outer jacket 110, the rotator 260 drives the electric telescopic rod 270 and the scraper 282 to rotate, so that the inner wall of the outer jacket 110 is cleaned, and the front and rear movement is combined for comprehensive cleaning. Then the vibrator 290 controls the vibration rod 291 to vibrate, so that the residue on the valve head 250 falls off, so that comprehensive cleaning can be achieved.

[0029] 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.
