Types of turning lathe valves

A turning lathe valve is a device used to measure the flow rate of a liquid or gas traveling through a pipeline. Several types of valve flow meters can be produced using a lathe machine. These include ball, bench, butterfly, gate, globe, wedge, plug, or check valves. The following table provides a summary of each valve's functions and specifications.

• Ball Valve: It is commonly used for on-off control of fluids with high flow rates. Its durability and low-friction seal makes it suitable for applications in the oil and natural gas industries.
• Bench Valve or Gate Valve: This type of valve is mainly used to control the flow of liquids. It is usually wide open or fully closed. The bench valve is manufactured using the sliding method or A.V. The former is machined with three lower parts perpendicular to the upper porch part. The part upper of the part lowers resembles a circle. In A.V, the lower part has a finer edge, and the slide is manually operated using a knob or a lever. The bench valve is commonly used in mechanical engineering and plumbing works. Unlike the gate valve that is usually used to control the flow of water, the bench valve can also be used to control the flow of steam.", li>
• Butterfly Valve: It is mostly used in large-diameter pipes to regulate and shut off fluid flow. The design comprises a circular disc mounted at the center of a pipe. The disc rotates horizontally, perpendicular to the flow of the fluid. The rotation of the disc controls the flow of the fluid. Because of its design, the butterfly valve provides the same functionality as a gate valve, but it is more suitable for regulating flow. Compared to gate valves, it is cheaper and requires less effort to operate. The valve can be fully opened or shut in less than a quarter turn. In terms of control accuracy, it is less precise than a globe valve but more precise than a gate valve. The valve is suited for the oil and water industries, but because it is used to regulate the flow of liquids, globe valves are mostly preferred for high-pressure systems.
• Globe Valve: It is designed to regulate the flow of a fluid. Unlike the gate valve which is usually used to fully open or completely close the flow of a fluid, the globe valve can be used to regulate the flow of a liquid. The globe valve is manufactured by machining a spindle that has a round or spherical shape. The spindle moves up and down in the valve body to control the flow of a liquid. Since it is mostly used to regulate the flow of liquids, the globe valve is suitable for high-pressure systems such as those found in hydraulic applications. The gate valve, on the other hand, is not ideal for such applications.",
• Wedge Valve or Check Valve: This type of valve only allows fluid to flow in one direction. It prevents the fluid from reversing its direction. The wedge valve is primarily used in a piping system to prevent the backflow of liquids. It gets its name from the method in which it operates. It comprises a movable part that is shaped like a wedge. When the liquid travels upward, it pushes the wedge upward, thus allowing the fluid to flow downwards. It works inversely when the fluid flows reverses its direction. The check valve is mostly used to prevent backflows in pipelines, but in some circumstances, it may be used to prevent blockage in mechanical devices. Because of its design and functionality, the check valve cannot be serviced. If it develops a fault, it must be replaced."

Specification and maintenance of turning lathe valve

The specifications of a CNC turning lathe valve manage the details of the machine in the industry.

• Maximum Workpiece Diameter:

  This is the largest diameter of a workpiece that the lathe can handle. For example, a maximum workpiece diameter of 500mm means the lathe can machine workpieces up to 500mm.

• Maximum Workpiece Length:

  This is the greatest length of a workpiece that the lathe can machine. For example, a maximum workpiece length of 800mm means the lathe can machine workpieces up to 800mm in length.

• Spindle Speed:

  The spindle speed of the valve seat lathe indicates the speed at which the workpiece rotates during machining. For example, a spindle speed of 1000-5000RPM means the spindle can rotate at a speed range between 1000 to 5000 revolutions per minute.

• Spindle Bore Diameter:

  It is the internal diameter of the spindle. For example, a spindle bore diameter of 60mm means the internal diameter of the spindle is 60mm. It is possible to pass through the workpiece or tools with a diameter up to 60mm.

• Control System:

  Such as FANUC, Siemens, etc. These are the names of the manufacturers of some turning valve controls. They are usually numerical control systems for lathes.

• Machine Dimensions:

  This is the length, width, and height of the lathe. For example, machine dimensions of 2000mm × 1500mm × 1700mm means the lathe occupies a space of 2000mm in length, 1500mm in width, and 1700mm in height.

Maintenance

For the machine turning valve to work longer and better, it is important to pay attention to its maintenance and use some tips to prolong its service life and avoid frequent failures.

• Keep cleanliness:

  It is very important to keep the machine and surrounding environment clean. Dirt and dust on the surface of the machine should be wiped out in time, and the workpiece and tools should be kept clean. This can avoid the occurrence of scratches and pollution during the processing.

• Lubrication and oiling:

  Regularly add lubricant and oiling to each moving part and bearing of the valve turning machine. Choose the proper lubricating oil according to the requirements of the operation manual, which is convenient to smooth the lubrication of the moving parts and reduce wear.

• Pay attention to temperature:

  Always pay attention to the temperature of the valves of lathe machines. The operating temperature should be in the range specified in the manual. If overheating occurs, the machine should be stopped immediately for cooling and inspection.

• Inspection and maintenance of parts:

  Regularly check and maintain important parts such as bearings, guides, and belts of the lathe. Ensure proper tightness and smooth belt transfer of the parts. The parts should be free of scratches and looseness and should be repaired or replaced in a timely manner if they are damaged or worn.

• Keep proper operating conditions:

  Ensure that the working environment of the valve lathe machine is provided with adequate ventilation and cooling. High temperatures and humidity may affect the operation and precision of the machine. Also, pay attention to prevent the entry of foreign objects such as dust and chips into the interior of the machine.
