金彩汇　　水阀开关方向按照顺时针方向来关闭。

金彩汇The opening and closing direction of the water valve should be clockwise.

金彩汇　　1、通常向右方向是开启，向左边是关闭，阀门顺时针关闭，逆时针打开。即阀门沿箭头指向S的方向关闭，阀门沿O的方向打开。其中S代表关，O代表开。如果有手轮，按右手拇指的方向转动将其打开，反过来是关闭。

金彩汇1. Usually, the valve opens to the right and closes to the left. The valve closes clockwise and opens counterclockwise. The valve closes in the direction pointed by the arrow towards S, and opens in the direction of O. S represents off, and O represents on. If there is a handwheel, turn it in the direction of your right thumb to open it, and vice versa to close it.

金彩汇　　2、水阀有球阀和闸阀，球阀的扳手在垂直于水管时关闭，当90度扳手拧紧或反转时，扳手在管道向前时打开，顺时针转动闸阀的手轮，打开逆时针螺丝，在使用过程中，闸阀不应过紧，以防止螺纹预制滑阀脱落。

金彩汇2. Water valves have ball valves and gate valves. The wrench of the ball valve closes when it is perpendicular to the water pipe. When the 90 degree wrench is tightened or reversed, the wrench opens when the pipe is forward. Turn the handwheel of the gate valve clockwise and open the counterclockwise screw. During use, the gate valve should not be too tight to prevent the threaded prefabricated slide valve from falling off.

　　3、阀门是一种用于开关的管路附件，如果按照功能来划分，有的是止回阀或者调节阀，有一种断阀能够起到开启和关闭的作用，一般在一些冷热源，包括管路支上面被用到，止回阀能够防止介质倒流，不允许流体反向流动。

3. A valve is a type of pipeline accessory used for switches. If divided by function, some are check valves or regulating valves, and there is a type of shut-off valve that can open and close. It is generally used in some cold and heat sources, including pipeline supports. Check valves can prevent medium backflow and do not allow fluid to flow in the opposite direction.
