中文简体PPR (Polypropylene Random) concealed valves are commonly used in plumbing systems to control the flow of water. These valves are installed behind walls or within concealed areas, offering a clean and aesthetically pleasing appearance. Let's explore the inner workings of PPR concealed valves:
1. Valve Body: The valve body is the main outer casing of the concealed valve. It is typically made of durable and corrosion-resistant PPR material. The body houses the internal components of the valve and provides the connection points for the inlet and outlet pipes.
2. Handle or Actuator: The handle or actuator is the component used to operate the valve. It can be a lever, knob, or wheel located on the outside of the wall for easy access. Turning the handle or actuator controls the opening and closing of the valve, allowing water flow or shutting it off completely.
3. Valve Core: The valve core is the internal component responsible for controlling the flow of water. It is connected to the handle or actuator and moves inside the valve body. When the handle is turned, the valve core rotates or moves to either allow or block the water flow.
4. Sealing Mechanism: Concealed valves incorporate a sealing mechanism to ensure a watertight seal when the valve is closed. This mechanism typically consists of rubber or elastomeric seals or O-rings located around the valve core or at the connection points. The seals prevent water leakage when the valve is in the closed position.
