[0027] This utility model discloses a one-way throttling valve core for a grab bucket oil port seat.
[0028] Reference Figures 1 to 4 A one-way throttle valve core for a grab bucket oil port seat includes a valve core body 1, which is threaded into the oil inlet hole of the oil port seat. Hydraulic oil enters the oil port seat through the oil inlet hole, passes through the one-way throttle valve core installed in the oil port seat, and then flows to the oil outlet, thereby realizing one-way throttle control of this oil circuit. Compared with conventional external one-way throttle valves, this solution has a compact structure, is more affordable, easier to maintain, and has lower costs.
[0029] Specifically, the valve core body 1 has a first hole 11 and a second hole 12. The diameter of the first hole 11 is larger than the diameter of the second hole 12. A step is formed between the first hole 11 and the second hole 12. A first blocking plate 13 is provided in the first hole 11. A compression spring 14 is provided at the end of the first blocking plate 13 away from the step. A plug 15 is threaded onto the valve core body 1. The plug 15 is located at the end of the compression spring 14 away from the first blocking plate 13. A flow groove 111 is provided on the side wall of the first hole 11. The flow groove 111 passes through the first hole 11 along the axial direction of the first hole 11. A through hole 151 is provided on the plug 15 to allow hydraulic oil to pass through.
[0030] Furthermore, the first blocking plate 13 is provided with a throttling orifice 131, which extends circumferentially along the first blocking plate 13 in a waist shape. A second blocking plate 16 is provided between the first blocking plate 13 and the step. The second blocking plate 16 is provided with an adjusting hole 161, which is waist-shaped. When the second blocking plate 16 rotates relative to the first blocking plate 13, the adjusting hole 161 and the throttling orifice 131 can switch between three states: non-overlapping, partially overlapping, and completely overlapping. An adjusting rod 162 is provided at the end of the second blocking plate 16 away from the first blocking plate 13. The adjusting rod 162 can be clamped with a special tool to drive the adjusting rod 162 to rotate, thereby driving the second blocking plate 16 to rotate. If the cross-sectional dimensions of the throttling orifice 131 to be adjusted are fixed, a limiting groove can be opened on the side wall of the second hole 12. Under normal conditions, the adjusting rod 162 is stuck in the limiting groove under its own elastic force to prevent the second blocking plate 16 from rotating during operation.
[0031] Working principle: Hydraulic oil enters the oil port seat through the inlet hole, passes through the one-way throttle valve core installed in the oil port seat, and then flows to the outlet port, thereby achieving one-way throttling control of this oil circuit. Compared with conventional external one-way throttle valves, this solution has a compact structure, is more affordable, easier to maintain, and has lower costs. The first blocking plate 13 and the second blocking plate 16 allow for control of the flow rate through the throttle orifice 131, improving application flexibility.
[0032] A type of grabber, as shown Figure 5 It includes a welding fixture 2, on which an oil port seat 21 is fixedly connected, and the oil port seat 21 contains the aforementioned one-way throttle valve core for the grab bucket oil port seat.
[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
