Description

一种抗变形截止阀门用合金阀板
技术领域
本发明涉及截止阀门制备领域，具体属于一种抗变形截止阀门用合金阀板。
背景技术
截止阀又称截门阀，属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。当介质由阀瓣下方进入阀门时，操作力所需要克服的阻力，是阀杆和填料的摩擦力与由介质的压力所产生的推力，关阀门的力比开阀门的力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。其阀板产品质量全凭人为控制、劳动密集型工艺，生产效率很低。
发明内容
本发明的目的是提供一种抗变形截止阀门用合金阀板，具有较强的抗压能力，且抗变形的特性优良，使用寿命长，安全可靠，适用于各种型号的大批量生产。
本发明的技术方案如下：
一种抗变形截止阀门用合金阀板，该合金阀板两侧壁分别设有斜槽，斜槽底部侧壁设有横向的凸筋，凸筋上方设有竖向的多个条筋，且该合金阀板中各合金元素重量百分比为：1.55%≤C≤1.76%，1.15≤Si≤1.25%，1.15%≤Mn≤1.25%，0.003≤P≤0.01%，0.004≤S≤0.006%，2.15%≤Cr≤2.25%，0.3%≤Mo≤0.5%，0.12≤Ni≤0.22%，0.01%≤Bi≤0.03%，0.07≤Ti≤0.11%，0.3%≤Re≤0.4%，余量为Fe和不可避免的杂质；将合金阀板加热至850-890℃并保温0.6－0.8h，油冷至不高于90℃后重新加热至650℃－710℃的温度范围并保温1-1.2h，之后水冷，水冷后进行铣斜槽，然后将凸筋、条筋按设计标准焊接于斜槽内。
该合金阀板中各合金元素重量百分比为：1.6%≤C≤1.7%，1.18≤Si≤1.22%，1.18%≤Mn≤1.22%，0.005≤P≤0.008%，0.0045≤S≤0.0055%，2.18%≤Cr≤2.22%，0.35%≤Mo≤0.45%，0.15≤Ni≤0.19%，0.015%≤Bi≤0.025%，0.075≤Ti≤0.095%，0.32%≤Re≤0.38%，余量为Fe和不可避免的杂质。
本发明在阀板的两侧分别设有凸筋和条筋，既减轻了阀板的重量，又保证了阀板的强度，工作状态具有较强的抗压能力，且抗变形的特性优良，使用寿命长，安全可靠，适用于各种型号的大批量生产。
