阀门的维修质量是要依据一定的标准进行考核与检测，以下是江阴市欧雷斯阀门维修厂的截止阀维修常用检测标准：
截止阀的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。阀杆的运动形式，有升降杆式（阀杆升降，手轮不升降），也有升降旋转杆式（手轮与阀杆一起旋转升降，螺母设在阀体上）。截止阀只适用于全开和全关，不允许作调节和节流。
截止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六时，操作力所需要克服的阻力，是阀杆和填料的磨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。近年来，从自密封的阀门出现后，截止阀的介质流向就改由阀瓣上方进入阀腔，这时在介质压力作用下，关阀门的力小，而开阀门的力大，阀杆的直径可以相应地减少。同时，在介质作用下，这种形式的阀门也较严密。我国阀门“三化给”曾规定，截止阀的流向，一律采用自上而下。
截止阀开启时，阀瓣的开启高度，为公称直径的25%～30%时，流量已达到最大，表示阀门已达全开位置。所以截止阀的全开位置，应由阀瓣的行程来决定

Commonly used cut-off valve maintenance quality inspection standards
Valve repair quality assessment and testing in accordance with certain criteria, the following is Oulei Si valve repair plant in Jiangyin City stop valve repair common testing standards:
The opening and closing parts of the globe valve is a plug-shaped valve, sealing surface flat or cone, the valve in a straight line along the center line of the fluid. Stem form of exercise, lift rod (stem down, hand wheel lift), lift the rotating rod (the hand wheel and stem with rotating movements, nuts located in the body). The cut-off valve is only applicable to the fully open and fully closed is not allowed to make adjustments and to reduce expenditure.
The cut-off valve is forced sealed valves, the valve is closed, the pressure must be applied to the valve to force the sealing surface does not leak. When the medium from the bottom of the valve into the valve 6, the operating force required to overcome the resistance, the friction force of the stem and the packing and thrust generated by the pressure of the medium, and close the valve force than the force to open the valve, Therefore, the diameter of the valve stem, otherwise they will be the failure of the stem top bend. In recent years, from the emergence of the self-sealing valve, globe valve flow direction of medium change from the top of the valve into the valve chamber, this time in the role of the media pressure, the force is small and close the valve, and force open the valve, the diameter of the stem can be reduced accordingly. The same time, the role of media, this form of valve more closely. Our valve "three to" has been provided, and closing the valve the flow of all top-down.
Cut-off valve is opened, the valve opening height is the nominal diameter of 25% to 30%, the flow has reached the maximum, indicating that the valve has reached the fully open position. Cut-off valve fully open position, to determine the stroke of the valve should be
