Embodiment Construction

[0009] As shown in the figure, the vibration damping and pressure regulating valve includes a valve body 1, a valve 3, and a spring 2. The valve 3 is installed on the valve body 1, and the outer diameter of the valve 3 matches the inner diameter of the valve body 1; the spring 2 is arranged on the valve body. Inside the body 1, one end is pressed on the adjusting screw 4 installed on the valve body 1, and the other end is pressed on the valve 3. Under the action of the spring 2, the bottom of the valve 3 is made to lean against the steps inside the valve body 1; The valve body 1 is provided with an overflow hole at the position of the valve 3; the bottom of the valve 3 is provided with a cylinder 5 extending outward, and the valve body 1 is provided with an inner chamber, and the cylinder 5 is arranged in the inner chamber and match with the inner cavity gap.

Abstract

The invention relates to a vibration attenuation and pressure adjustment valve. The valve includes a valve body, a movable door and springs; the movable door is installed on the valve body, and the outer diameter of the movable door is matched with the inner diameter of the valve body; the springs are arranged in the valve body, one end of each spring is pressed and installed on an adjustment screw on the valve body, and the other end of each spring is pressed on the movable door; a column extending to the exterior is arranged on the bottom of the movable door, an inner cavity is formed in thevalve body, and a gap is reserved between the inner cavity and the column arranged in the inner cavity. Through arrangement of the column and the inner cavity, vibration energy is absorbed, the system pressure is stabilized, impact caused by vibration on the fatigue performance of the pressure adjustment valve can be eliminated at the same time, resonance is avoided, and therefore the reliabilityand stability of the valve during use are improved.

Description

technical field [0001] The invention relates to a pressure regulating valve, in particular to a vibration reducing and pressure regulating valve. Background technique [0002] The working principle of the pressure regulating valve involved in the present invention is as follows: when the lubricating oil pressure of the system exceeds the specified pressure upper limit, the hydraulic pressure will overcome the spring force of the pressure regulating valve to open the valve, and the pressure regulating valve overflows. If the system lubricating oil pressure continues to increase, Then the opening of the pressure regulating valve increases, and the overflow capacity increases until the lubricating oil pressure is stable, realizing the pressure protection function; when the lubricating oil pressure of the system is lower than the specified pressure lower limit, the valve will overcome the hydraulic pressure under the action of the spring pressure and reduce the opening degree of ...
