今天的两个零件一个是壳体，一个是阀体。老规矩还是先给出零件图纸，第一个零件壳体的零件图如下，从图中我们能够清楚的看到有四个部分，左上角是主视半剖图，右上角是左视图，而左下角的是俯视图，右下角则是A视角的图，所画的是中间板子的部分。

Today's two parts are a housing and a valve body. As usual, it is better to provide the part drawing first. The part drawing of the first part shell is as follows. From the drawing, we can clearly see that there are four parts: the upper left corner is the front view half section, the upper right corner is the left view, and the lower left corner is the top view. The lower right corner is the A view, and the part of the middle plate is drawn.

对于这个零件来说我们大体可以分为四个部分来画，首先选主体部分，这个部分主要由矩形的板子和最大的方块组成，我们先画板子，并将孔打好，以此作为基准。然后在板子上画最大的矩形体，主要图中的尺寸。这一部分注意两边有两个突起，从左视图中能很明显看出来，中间为两个M10的螺纹孔。然后就剩下下面部分，右边部分以及内部的洞。先画下边或者右边都一样，这里主要是旋转凸台完成。内部的孔洞可以使用旋转切除也可以使用拉伸切除。

For this part, we can roughly divide it into four parts to draw. First, we select the main body, which is mainly composed of rectangular boards and the largest square. We will draw the boards first and drill the holes as a reference. Then draw the largest rectangle on the board, with the main dimensions shown in the diagram. Note that there are two protrusions on both sides in this section, which can be clearly seen from the left view, with two M10 threaded holes in the middle. Then only the lower part, the right part, and the inner hole remain. Draw the bottom or right side first, it's the same. This is mainly done by rotating the convex platform. The internal holes can be removed by rotation or stretching.

第二个零件是阀体，阀体是我们的老朋友了，但是阀体的类型多种多样，下面这种就比较特别。虽然内部依然是圆柱形孔洞，外部确实方体的。这个零件图有五个视图，左上角是主视半剖图，左下角是俯视图，上方中间是右视图，侧视图一般都会给，但是不同的图纸可能给的方向不一样，这主要是根据零件体的特征所定的。正下方的是A视角图，右上角是B视角图纸。

The second component is the valve body. The valve body is our old friend, but there are various types of valve bodies, and the one below is quite special. Although the interior is still a cylindrical hole, the exterior is indeed square. This part drawing has five views, with the upper left corner being the front half section view, the lower left corner being the top view, and the upper middle being the right view. Side views are usually given, but different drawings may give different directions, mainly based on the characteristics of the part body. The view below is from perspective A, and the top right corner is from perspective B.

画图首先先要找到零件的主体部分，这个零件很明显就是中间的矩形体。首先画出这个主体部分后，在画其他部分，其他部分顺序没有影响，因为都是在主体的不同方位且没有相关性。在画右上角和正下方的图形时，先画出圆形部分再用直线连接，设置相切即可。其余部分正常绘制。

The first step in drawing is to find the main body of the part, which is clearly the rectangular body in the middle. After drawing the main part first, draw the other parts. The order of the other parts does not affect because they are all in different directions of the main body and have no correlation. When drawing the shapes in the upper right corner and directly below, first draw the circular part and then connect it with a straight line, setting tangency. The remaining parts are drawn normally.
