根据实际情况，如果是一个垫片应该放在螺母一侧，垫圈孔带倒角的一侧应该和螺母接触，不能装反。
According to the actual situation, if it is a gasket, it should be placed on one side of the nut, and the chamfered side of the gasket hole should contact the nut, instead of being installed reversely.
如果是大六角头的螺栓，应该装两个垫圈，螺栓一侧和螺母一侧各一个，一个垫圈孔带倒角的一侧应该和螺栓头接触，另外一个垫圈孔带倒角的一侧应该和螺母接触，不能装反。
If it is a bolt with large hexagon head, two washers should be installed, one on one side of the bolt and one on the nut side. The chamfered side of one washer hole should contact the bolt head, and the chamfered side of the other washer hole should contact the nut instead of being reversed.

Basic requirements for bolted connection
普通螺栓作为性连接螺栓时应符合下列要求：
When ordinary bolts are used as permanent connecting bolts, the following requirements shall be met:
1.对一般的螺栓连接，螺栓头和螺母下面应放置平垫圈，以增大承压面积。
1. For general bolt connection, flat washers shall be placed under the bolt head and nut to increase the pressure bearing area.
2.螺栓头和螺母侧应分别放置平垫圈，螺栓头侧放置的平垫圈一般不应多于2个，螺母侧放置的平垫圈一般不应多于1个。
2. Flat washers shall be placed on the bolt head and nut side respectively. Generally, no more than 2 flat washers shall be placed on the bolt head side, and no more than 1 flat washer shall be placed on the nut side.
3.对于设计有要求防松动的螺栓、锚固螺栓应采用防松动装置的螺母或弹簧垫圈，弹簧垫圈需要设置在螺母一侧。
3. For bolts and anchor bolts designed to prevent loosening, nuts or spring washers of anti loosening devices shall be used, and spring washers shall be set at the side of nuts.
4.对于承受动荷载或重要部位的螺栓连接，应按设计要求放置弹簧垫圈，弹簧垫圈设置在螺母一侧。
4. For bolted connections bearing dynamic load or important parts, spring washers shall be placed according to design requirements, and the spring washers shall be set at one side of the nut.
5.对于工字钢、槽钢类型钢利用斜面连接时应使用斜垫圈，使螺母和螺栓头部的支承面垂直于螺杆。
5. For I-shaped steel and channel steel connected by inclined plane, inclined washer shall be used to make the bearing surface of nut and bolt head perpendicular to the screw.
