Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic systems, in particular to an acceleration valve for a hydraulic system. Background Art

[0002] Under certain pressure conditions, hydraulic oil circulates in the hydraulic system, and changes the size of the output force through the change of the size of its force-bearing area, thereby performing external work. Generally, the driving force of the hydraulic system is provided by the hydraulic motor. For the hydraulic system installed on the car (such as the feed transport vehicle), the power take-off is usually used to take power from the car engine as the driving force of the hydraulic system. In this case, there is a problem that the output power of the hydraulic system is not easy to adjust;

[0003] After searching, the applicant found that a Chinese patent disclosed "an acceleration valve for a hydraulic system", and its publication (announcement) number is "CN201396331Y". The patent mainly welds a left valve cover on the left end of the valve cylinder, and the sealing nut is screwed on the left valve cover, and the connecting pipe used to access the hydraulic system is crimped on the end face of the left valve cover, and an O-ring is provided between the two. However, it is difficult to achieve adjustable flow rate of the oil inside the cylinder in the above comparative example. In actual use, the unstable flow rate may cause hydraulic shock. For this reason, we propose an acceleration valve for a hydraulic system. Utility Model Content

[0027] In one embodiment of the present invention, an oil inlet pipe 4 is disposed on the front of the connection block 31 , and the outer surface of the oil inlet pipe 4 penetrates the back of the connection block 31 connected to the inside of the accelerating tube 1 and is fixedly connected to the front of the accelerating tube 1 .

[0030] Example 1, please refer to the attached Figure 1 -Attached Figure 4 The anti-collision column 32 helps to improve the stability of the entire protection frame, so that the frame is not easily deformed or damaged when subjected to an impact. The flow control blade 25 can finely control the flow of the hydraulic oil by adjusting the angle or position of the blade, thereby achieving precise control of the speed of the actuator in the hydraulic system.

Secondly, when the acceleration valve is installed, the anti-collision component 3 arranged on the outside can protect the acceleration valve. At this point, the entire work process is completed.
