Its male and female threaded connections ensure sealing performance and are suitable for industries such as chemical, pharmaceutical, and food processing. The compact structure and easy operation make this ball valve an ideal choice for industrial vacuum pipelines.
A disc ball valve is a type of valve in which the ball rotates around the centerline of the valve body to open and close. It is mainly used in pipelines to cut off, distribute, and change the flow direction of the medium
Internal and external threaded ball valves are ball valves that use threaded connections, with internal and external threads at both ends, making it easy to connect with pipelines or other equipment,
The working principle of internal and external threaded ball valves is based on the rotation of the sphere. When the handle or driving device drives the valve stem to rotate, the valve stem drives the ball to rotate 90 ° inside the valve body. When the through-hole on the sphere is aligned with the pipeline axis, the valve is fully open and the medium can freely pass through; When the sphere rotates 90 ° to make the through-hole perpendicular to the pipeline axis, the valve is in a fully closed state, and the medium is cut off, making it impossible to pass through
One piece ball valve: using a one-piece valve body, threaded connection, the diameter of the ball is slightly smaller than the diameter of the pipeline, and the flow rate is relatively small. It is commonly used for small-sized valves and has a simple structure
Two piece ball valve: The valve body consists of two parts, and the connection forms include thread, butt welding, socket welding, etc. The diameter of the ball is the same as that of the pipeline, which is easy to disassemble and has good sealing effect
Three piece ball valve: The valve body consists of three parts, with a full bore design, easy disassembly and maintenance, and stronger pressure bearing capacity. It is usually used for larger and more important valves
- 1/2" MNPT x 1/2" FNPT thread for connecting male and female pipe fittings
- Standard port flow for smaller valve size, each valve individually tested for maximum safety about Water, Oil, and Gas(no freezing)
- Serviceable Valve - Threaded Disassembly, Male and Female NPT Ports
- 90 degree valve closing range, the handle can close the valve by rotating it to either side of the valve body
- Working temperature of -20°F to 410°F, Fast 1/4 turn open or closed operation
Structural characteristics
Valve body: It is usually made by casting process and has structures such as integral, two-piece, and three piece. The integral valve body structure is simple and compact, but maintenance is not very convenient; Two piece and three piece valve bodies are easy to disassemble and maintain, and can be selected according to different usage needs.
Sphere: It is a key component of a ball valve, usually spherical in shape, with a circular through-hole on the sphere. When the sphere rotates, the through-hole aligns or is perpendicular to the pipeline axis, thereby achieving the opening and closing of the valve.
Valve seat: Made of elastic sealing materials such as polytetrafluoroethylene (PTFE), it has good sealing and corrosion resistance, and can form a reliable seal between the ball and the valve seat to prevent medium leakage.
Valve stem: used to connect a ball and a handle or drive device, transmit torque, and enable the ball to rotate inside the valve body. The valve stem adopts a bottom mounted structure with reverse sealing. When the valve chamber is abnormally pressurized, the valve stem will not be flushed out, ensuring the safety of the valve.
Handle or driving device: Manually operated ball valves with internal and external threads are usually equipped with handles, which can be rotated to control the opening and closing of the ball; Electric, pneumatic, or hydraulic drive devices can also be installed as needed to achieve remote control or automated operation
advantage
Low fluid resistance: Its resistance coefficient is equal to that of a pipe section of the same length, and the medium passes smoothly.
Simple structure, small size, light weight: easy to install, disassemble, and transport, occupying little space.
Tight and reliable: The sealing surface material is widely used, such as plastic, with good sealing performance and can also be widely used in vacuum systems.
Easy to operate: quick opening and closing, only need to rotate 90 ° from fully open to fully closed, and convenient for remote control.
Easy maintenance: Ball valves have a simple structure, and the sealing rings are generally movable, making disassembly and replacement relatively convenient.
Wide applicability: The diameter can range from a few millimeters to several meters, and can be applied to high vacuum to high pressure.
The sealing surface is not easily eroded: When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the medium passing through will not cause erosion of the valve sealing surface.
Working principle
Opening process: The valve stem drives the ball to rotate, gradually aligning the through-hole on the ball with the pipeline axis, and the medium begins to pass through the valve.
Closing process: The handwheel rotates to drive the valve stem, and the angular flat surface at the bottom of the valve stem mechanically wedges and presses the ball tightly against the valve seat, achieving complete sealing and cutting off the flow of the medium.
Structural characteristics
Friction free opening and closing: completely solves the problem of traditional valves affecting sealing due to mutual friction between sealing surfaces.
Top mounted structure: Valves installed on pipelines can be directly inspected and maintained online, effectively reducing device downtime and lowering costs.
Single seat design: eliminates the problem of abnormal pressure rise in the valve chamber medium affecting safety during use.
Low torque design: The valve stem with a special structural design can be easily opened and closed with just a small handle.
Wedge sealing structure: The valve relies on the mechanical force provided by the valve stem to press the ball wedge onto the valve seat for sealing, ensuring that the sealing performance of the valve is not affected by changes in pipeline pressure difference, and the sealing performance is reliably guaranteed under various working conditions.
Self cleaning structure of sealing surface: When the sphere tilts away from the valve seat, the fluid in the pipeline passes uniformly along the sealing surface of the sphere at a 360 ° angle, not only eliminating the local flushing of high-speed fluid on the valve seat, but also washing away the accumulated substances on the sealing surface, achieving the purpose of self-cleaning.
