根據實際情況，如果是一個墊片應該放在螺母一側，墊圈孔帶倒角的一側應該和螺母接觸，不能裝反。
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.
如果是大六角頭的螺栓，應該裝兩個墊圈，螺栓一側和螺母一側各一個，一個墊圈孔帶倒角的一側應該和螺栓頭接觸，另外一個墊圈孔帶倒角的一側應該和螺母接觸，不能裝反。
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.
螺栓連接基本要求
Basic requirements for bolted connection
普通螺栓作為性連接螺栓時應符合下列要求：
When ordinary bolts are used as permanent connecting bolts, the following requirements shall be met:
1.對一般的螺栓連接，螺栓頭和螺母下面應放置平墊圈，以增大承壓面積。
1. For general bolt connection, flat washers shall be placed under the bolt head and nut to increase the pressure bearing area.
2.螺栓頭和螺母側應分別放置平墊圈，螺栓頭側放置的平墊圈一般不應多于2個，螺母側放置的平墊圈一般不應多于1個。
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.對于設計有要求防松動的螺栓、錨固螺栓應采用防松動裝置的螺母或彈簧墊圈，彈簧墊圈需要設置在螺母一側。
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.對于承受動荷載或重要部位的螺栓連接，應按設計要求放置彈簧墊圈，彈簧墊圈設置在螺母一側。
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.對于工字鋼、槽鋼類型鋼利用斜面連接時應使用斜墊圈，使螺母和螺栓頭部的支承面垂直于螺桿。
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.
