探究水阀S和O的含义

o on the valve means open, while s means shut. Most valves have this mark on the handle, which makes it convenient for people to use when opening or closing the valve. The direction of rotation is also marked. If the valve needs to be fully opened, the handle needs to be closed half or one turn first, which can protect the valve stem and transmission mechanism.

Where are water valves generally located in homes?

1. Generally, they are located around the water meter. After finding it, turn it clockwise to shut it off. There is still water in the pipe after it is shut off, so just open the faucet to drain the water inside.

2. If the valve is indoors, it is usually in the corner of the kitchen. If the valve is outdoors, it should be downstairs. Some residential areas have a water valve well downstairs, which is about 50 centimeters deep. Then find your own water valve and turn it off.

What are the types of water valves?

1. Globe valve

It is mainly used to connect or cut off the medium in the pipeline and is generally used for medium and small diameter pipelines. It has a wide range of applicable pressure and temperature.

2. Check valve

The check valve is a valve that can automatically prevent fluid from flowing back, also known as a non-return valve. When the fluid flows from the inlet side to the outlet side, when the pressure on the inlet side is lower than that on the outlet side, the valve flap automatically closes under the action of fluid pressure difference, gravity and other factors to prevent fluid backflow. Check valves are usually used at the outlet of pumps.

3. Safety valve

The function of safety valves is to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value, so as to achieve the purpose of safety protection.

4. Gate valve

The gate valve is one of the commonly used shut-off valves, mainly used to connect or cut off the medium in the pipeline, and is not suitable for regulating the flow rate of the medium.

5. Diversion valve

Diversion valves include various distribution valves and steam traps, etc., which are used to distribute, separate or mix the medium in the pipeline.
