What Is the Structure of Ball Valve?

The structure of a ball valve usually consists of the following parts:

1. Ball: The ball is the core component of the ball valve, usually made of metal or plastic. The channels and holes inside the sphere are connected with the fluid channel, and the opening and closing of the fluid and the adjustment of the flow rate are controlled by rotating the sphere.

2. Valve stem: The valve stem is a part that connects the ball and the operating mechanism. It rotates the ball to control the flow of fluid by rotating the operating mechanism.

3. Sealing surface: The sealing surface is the part between the ball and the valve seat, which controls the flow of fluid through the pressure seal between the ball and the valve seat.

4. Valve seat: The valve seat is a part that supports the ball and provides a sealing surface, usually made of elastic material, such as polytetrafluoroethylene (PTFE), etc.

5. Body: The valve body is the shell of the ball valve, which supports the ball, valve seat, valve stem, and other components, and connects the pipeline. Usually made of metal or plastic.

6. Operating mechanism: The operating mechanism is a component that controls the rotation of the sphere, usually including handles, gears, electric or pneumatic devices, etc.

What Are the Advantages of Brass Ball Valve Compared with Other Valves?

Compared with other valves, the brass ball valve has the following advantages:

1. Good sealing performance: The sealing surface between the ball and the valve seat of the brass ball valve is precisely machined, and the sealing performance is good, which can effectively prevent fluid leakage.

2. Large flow capacity: The channels and holes inside the brass ball valve are relatively large, and the flow capacity is better than other valves, which can meet the fluid control needs of large flow.

3. Small operating force: The ball of the brass ball valve controls the flow of fluid through rotation, which requires less operating force than other valves.

4. Long service life: Brass ball valve has a simple structure, no complicated discs or rotating parts, easy maintenance, and long service life.

5. Applicable to a variety of fluids: A brass ball valve can be applied to different fluids such as various liquids, gases, and steam.

6. Quick switch: The operating mechanism of the brass ball valve can quickly turn the ball from fully open to fully closed, and the fluid control responds quickly.

How the Faucet Ball Valve Works

A faucet ball valve, also known as a ball faucet or ball valve faucet, operates on the principle of using a ball with a hole through it to control the flow of water. The ball valve is a central component within the faucet's mechanism, allowing users to regulate water flow and temperature by manipulating the position of the ball inside the valve body.

Here's how a faucet ball valve works:

Basic Structure: A ball faucet valve consists of a hollow ball with a port (hole) drilled through it. The ball sits within the valve body, which contains inlet ports for hot and cold water supply lines.

Rotational Control: The handle or lever attached to the faucet controls the rotation of the ball inside the valve body. As the handle is turned, the ball's position changes, aligning or blocking the inlet ports and the outlet port.

Water Flow Regulation: When the ball's port aligns with the water inlet ports, water flows through the valve and into the faucet's spout. The amount of water flow is determined by how far the ball's port is open to the inlet ports. Rotating the handle controls the degree of the opening, regulating the water flow.

Temperature Control: Ball valves designed for single-handle faucets also incorporate a mixing mechanism. By rotating the handle, users can adjust the proportions of hot and cold water entering the faucet. The ball's port aligns differently with the hot and cold water inlets, determining the temperature of the water that exits the faucet.

Sealing and Shut-Off: When the ball's port is fully closed, it blocks the water inlet ports, shutting off the water supply. The ball's design, combined with seals and gaskets, ensures a watertight seal when the faucet is in the off position.

Durability: Ball valves are known for their durability due to their simple design and fewer moving parts. This makes them less prone to wear and leaks over time.
