The valve core is made of stainless steel material, which has good corrosion resistance and mechanical strength. The spring is made of high-quality spring steel material, which has high elasticity and fatigue resistance. The sealing ring is made of high-quality rubber material, which has good sealing performance and corrosion resistance.

三、產品工作原理

3. Product working principle

500X持壓泄壓閥的工作原理是基于壓力控制和泄壓功能。當管道系統中的壓力超過設定值時，閥芯會受到壓力的作用，向上移動，使閥門開啟，將多余的壓力釋放出去，以保持管道系統中的壓力在安全范圍內。當管道系統中的壓力降低到設定值以下時，閥芯會受到彈簧的作用，向下移動，使閥門關閉，以保持管道系統中的壓力穩定。

The working principle of 500X pressure relief valve is based on pressure control and pressure relief functions. When the pressure in the pipeline system exceeds the set value, the valve core will be acted upon by the pressure, move upward, open the valve, and release the excess pressure to keep the pressure in the pipeline system within the safe range. When the pressure in the pipeline system drops below the set value, the valve core will be acted upon by the spring, move downward, close the valve, and keep the pressure in the pipeline system stable.

四、產品應用范圍
