[0017] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0018] Example 1
[0019] like Figure 1-3 As shown, this embodiment provides a plate-type relief valve assembly. The plate-type relief valve assembly includes a rectangular valve body 1, a relief valve 2 installed on the left side of the valve body 1, an oil source port 3 and an oil return port 4 provided on the front side of the valve body 1, and a plurality of mounting holes 5 provided on the front and rear sides of the valve body 1; the relief valve 2 includes an oil inlet 21 and an oil outlet 22, the oil inlet 21 being connected to the oil source port 3, and the oil outlet 22 being connected to the oil return port 4.
[0020] In this embodiment, the plate-type relief valve assembly adopts a plate-type mounting structure. The plate-type mounting structure does not require additional connection to external oil pipes; that is, the oil source port 3 and the oil return port 4 are directly attached to the oil tank, reducing installation space and making it safer and more reliable.
[0021] Mounting holes 5 are eight through holes located on the front and rear sides of valve body 1, with the eight through holes evenly distributed on the front and rear sides of valve body 1.
[0022] Relief valve 2 is a cartridge valve; relief valve 2 is a direct-acting relief valve; valve body 1 is made of alloy steel. In this embodiment, the direct-acting relief valve is a normally closed pressure limiting valve, often used to protect hydraulic components from transient pressure shocks. When the pressure at the oil source port 3 reaches the pressure set value of relief valve 2, relief valve 2 begins to overflow into the oil tank, throttling to limit the pressure rise. This type of valve offers smooth adjustment, low noise, virtually zero leakage, strong resistance to oil contamination, anti-clogging properties, and fast response.
[0023] The working principle of this utility model is as follows: In the initial state, the relief valve 2 is in a normally closed state, that is, the oil inlet 21 and the oil outlet 22 of the relief valve 2 are not connected. Hydraulic oil enters from the oil source port 3. When the pressure of the incoming hydraulic oil reaches the preset pressure of the relief valve 2, the valve core of the relief valve 2 moves to the open state, that is, the oil inlet 21 and the oil outlet 22 of the relief valve 2 are connected. At this time, the hydraulic oil will be unloaded through the relief valve 2 and flow to the return port 4 to the oil tank.
[0024] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
