Embodiment Construction
[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0022] Please refer to Figure 1 to Figure 4 As shown, in this embodiment, a flow control buffer valve includes a valve body 1, a liquid outlet 7 is opened at the bottom of the valve body 1, an opening is provided at the top, and a valve cover 2 is connected. The valve cover 2 is provided with a liquid inlet 8, and the center of the valve body 1 is provided with a valve core 3 which can move up and down. The valve core 3 is a cylindrical structure, and the inner walls of the front and rear sides of the valve body 1 are There is an arc-shaped groove 4 matching with the valve core 3, and the left and right sides of the valve body 1 are provided with a lim...

The invention discloses a flow control buffer valve. The flow control buffer valve comprises a valve body; the bottom part of the valve body is provided with a fluid outlet, and the top part thereof is provided with an opening; a well is connected with a valve cover, and a fluid inlet is arranged on the valve cover; the center at the inner part of the valve body is provided with a valve core capable of vertically moving; an elastic device is arranged between the valve core and the bottom face at the inner part of the valve body, an upper limiting slot is arranged on the valve cover, and a lower limiting slot is arranged on the valve body; the upper limiting slot is interconnected with the fluid inlet, and the caliber of the upper limiting slot is more than that of the fluid inlet; the lower limiting slot is interconnected with the fluid outlet, and the caliber of the lower limiting slot is more than that of the fluid outlet; the center of the upper end of the valve core is provided with a fluid inlet, and the center of the lower end thereof is provided with a fluid outlet; the fluid inlet is interconnected with the fluid outlet, and the caliber of the fluid inlet is less than the caliber of the fluid inlet. The impulse pressure of the hydraulic pressure is generated in the valve body, and pressure is effectively reduced; and thereby, the flow control buffer valve overcomes the bursting and avoids the damage of a cooler.
Description
technical field [0001] The invention relates to a valve, in particular to a flow control buffer valve. Background technique [0002] The valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium. [0003] At present, the plate-fin heat exchangers used in construction machinery generally have the problem of bulging, and the reason is analyzed: In the hydraulic system of construction machinery, due to the change of hydraulic oil flow rate, the local oil pressure of the cooler increases instantaneously due to the accumulation of hydraulic oil, which leads to channel failure. burst. According to incomplete statistics in the industry, the explosion rate of hydraulic oil heat exchangers for pump trucks alone reaches 30%, and the explosion of coolers will cause a series of problems for users: [0004] 1. The machine cannot work, delaying the progress of the project; [0005] 2. If the hydraul...
