Ball Check Valve

  Check valve refers to a valve whose opening and closing part is a round valve disc and acts by its own weight and medium pressure to block the backflow of the medium. This kind of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belongs to an automatic valve.

  Ball check valve is a special kind of check valve, it is a multi-demand, multi-channel, multi-cone reverse fluid structure of the check device, mainly by the front and back valve body, rubber ball, cone body, etc., with good sealing, minimal flow resistance and other performance advantages, is widely used in a variety of pipeline systems, used to prevent the backflow of the medium, pump and drive machinery reversal.

  The ball check valve has a simple structure and is mainly composed of a spherical device and a valve body. The spherical device is composed of a ball cover and a rubber ball, which is processed into a ball core by a steel plate and lined with a rubber layer to maintain a certain degree of elasticity and sufficient strength. Its working principle is: the rubber ball in the ball cover for short stroke rolling to achieve the valve opening and closing. When the pump is started, the water under the action of pressure flushes the rubber ball, so that the rubber ball rolls to the right side, the cone body in the rear valve body fixed its position, the check valve is opened; After the pump stops, due to the return water pressure in the piping system, the rubber ball is forced to roll to the left front valve body to achieve the closing of the check valve. The rubber ball is made of hollow steel ball, and the rubber with good elasticity can ensure the sealing and reduce the damage to the pipeline system during the valve closing process. The cone body with holes has a fixed effect on the steel ball when the valve is opened and eliminates the pressure of the contact area between the rubber ball and the cone body, so that the contact is surface contact, and reduces the hydraulic loss caused by the shaking of the rubber ball in the valve body.

  Advantages of ball check valves
(1) Long service life, smooth operation, safe and reliable, good sealing performance;
(2) The resistance coefficient is small. Because it is a spherical valve, water flows almost straight through the valve body;
(3) The shock absorption effect is good, and the water quality is not strict

  Ball check valves are used in a wide variety of piping systems, including but not limited to:
Water system: Used to prevent water flow back from pumps or other equipment, to protect pumps and piping systems.
Steam system: effectively prevent steam leakage and reverse flow to ensure the normal operation of the steam system.
Air pipe: Prevent air backflow in the air pipe and maintain the normal flow of air in the pipe.
Industrial field: such as food, beverage, wine, pure water, pharmaceutical, cosmetics, chemicals and other industries, used to protect the smooth transmission of fluids and prevent the return of media.

  The ball check valve is a reliable and efficient device that is widely used in various industries. Its simple design, reliable performance, and durability make it an essential component in many fluid control systems. With the increasing demand for high-pressure applications and the need for backflow prevention, the ball check valve will continue to be an important component in the fluid control industry.
