- Q: Is the ball valve installed in a direction?
- Valve installation generally no direction required, any end of the valve can be mounted on the upper end. If the valve marked the direction, then it should be installed in the direction of tagging installed.
- Q: What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?
- Pneumatic angle seat valve is the use of reciprocating actuators, usually in use to withstand fluid work pressure at 1.6MPa. Pneumatic ball valve is to use rotary actuator, to bear high fluid pressure. In normal use, the reciprocating actuator is characterized by its service life over the length of the rotary actuator. Two: easy maintenance. Three: the price is cheap. Personal recommendations in fluid pressure below 1.6MPa, or pneumatic angle seat valve is better?. High pressure, less opening frequency, pneumatic ball valve is appropriate.
- Q: What are the advantages and disadvantages of the two functions of the pneumatic ball valve actuator?
- Pneumatic ball valve actuator is divided into double action and single action two modes of work.Working principle of double action mode:When the compressed air enters the middle cavity between the two pistons of the cylinder from the air inlet (2), the two pistons are separated and moved toward the two ends of the cylinder, and the air at the two ends of the air chamber is discharged through the air port (4). At the same time, the two piston rack synchronously drives the output shaft (gear) to rotate in an anticlockwise direction. On the contrary, when the air source pressure passes through the air inlet (4) into the air chamber at the end of the cylinder, the two piston moves toward the middle of the cylinder, and the air in the middle air cavity is discharged through the air port (2). At the same time, the two piston rack synchronously drives the output shaft (gear) to rotate in clockwise direction. (if the piston is mounted in opposite directions and the output shaft rotates in reverse direction, that is, double acting reverse type).
- Q: What's the advantage of using an electric ball valve?
- Shanghai power code solenoid valve on the official website introduced the benefits of four point electric ball valve, 1. for two cutting, adjusting the occasion. 2., electric ball valve can be achieved on the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanks and other transport pipeline cutting off the medium and circulation. 3., good sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing, and even cut off. 4. 、 electric valve is small, light weight, big thrust, powerful function, servo amplifier built-in, easy to operate, high reliability.
- Q: Is the drain valve the same as the ball valve?
- Drain valve and ball valve function is not the same.The main function of the drain valve is to protect the safety of the pipeline. When the water pressure is too large, it will drain automatically and reduce the pressure of the pipeline. It is a valve installed in the pipeline system.
- Q: What does "2P" ball valve mean?
- The left valve body and the right valve body consist of two parts.
- Q: Daily maintenance and common maintenance of ball valves, Q347F-16C and Q41F-16C
- Structural type code:Floating type: 1 means through flow, 2 indicates Y type three pass, 4 represents L type three pass, and 5 represents T type three pass;Fixed type: 0 represents the straight through of the hemisphere, the 6 represents the four channel, the 7 indicates the through flow, the 8 represents the L type three pass, and the 9 represents the Y type three pass;Sealing material: B Babbitt, fluorine rubber, F F46, H direct machining of fluorine lining, rubber lining, stainless steel J M Monel alloy, N nylon plastics, Monel P, Y alloy, W valve;Pressure rating code: 16 said the pressure of 16 kg (1.6Mpa) up to 64Mpa; 150LB said American Standard pound pressure, maximum pressure rating up to 2500LB (150LB=1.6MPA/300LB=2.5-4.0mpa/400LB=6.4mpa/600LB=10mpa); 5K said on stage pressure, the maximum pressure of 63K;Body material: A titanium and titanium alloy, C steel, I stainless steel, chrome molybdenum steel, P18-8 stainless steel, S plastic, RMo2Ti.
- Q: Daily maintenance of ball valve
- The new parts need to be cleaned before assemblingThe assembly should have metal fragments, fiber, fat is not allowed (except the requirement to use) dust and other impurities, foreign matter contamination, adhesion or remain in part into the cavity on the surface or, if the packing is micro discharge, to lock the stem nut.Note: do not lock too tight, usually lock 1/4 circle to 1 laps, the leak will stop.(A) disassemblyMake the valve in a half open position, flush and remove dangerous substances that may exist inside and outside the valve body.Close the ball valve, remove the connecting bolts and nuts on both sides of the flange, and then remove the valve completely from the line.In order to remove the drive - actuator, a connecting bracket, lock washer, stem nut, butterfly spring, glam, wear plates, valve stem packing.Remove the body cap connecting bolts and nuts, separate the valve cover from the valve body and take off the valve cover washer.Make sure the ball is in the "off" position, which can be easily removed from the valve body and then removed from the valve seat.A hole in the body downward nudge stem until completely removed, and then remove the packing ring and the O.Caution: Please operate carefully to avoid galling, stem surfaces and body packing box seals.B) reassembleCleaning and inspection of the parts removed, it is strongly recommended to use spare parts package replacement valve seat and valve cover, gaskets and other seals.Assemble in reverse order of disassembly.Cross the locking flange bolts with the specified torque.Lock the stem nut with the specified torque.
- Q: What are the applicable conditions of ball valves?
- As the ball valve is usually made of rubber, nylon and PTFE as the seat ring material, so its use temperature is limited by the seat ring material. Ball valve is the cut-off role of the metal sphere in the role of the media, in the plastic valve seat between each other to complete the compression (float ball valve). Seat ring sealing ring under certain contact pressure, elastic-plastic deformation occurs in some areas.
- Q: Ball valve, PTFE pad inappropriate choice, is not easy to bad ah?
- 120 - 150. TemperatureChasing the answerYes, but not in a high temperature for a long time, like more than 180 degrees centigrade. Because the gasket can not be used after deformation, it will cause valve leakage.
