Q:PPR which side of the ball valve is open, which face is off
Hello, I am glad to answer for you. O is on, s is off. I hope I can help you.
Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?
Stop valve: a valve that closes the valve and moves along the center line of the valve seat. According to this form of valve movement, the valve seat opening change is proportional to the valve stroke. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. Therefore, this type of valve is very cooperative for cutting or regulating and throttling.Advantages: in the process of opening and closing, because the friction between the valve and the sealing surface of the valve body is smaller than that of the gate valve, the utility model has the advantages of wear resistance. Second, the opening height is generally only 1/4 of the seat channel; therefore, it is much smaller than the gate valve; usually there is only one sealing surface on the valve body and the disc; therefore, the manufacturing process is better and the service is easy to maintain. Because its packing is generally a mixture of asbestos and graphite, it has a higher temperature resistance. Steam valves are normally used with stop valves.Disadvantages: as a result of the medium through the valve flow direction has changed, so the minimum flow resistance valve is higher than most other types of valves; second, due to longer travel, opening slower than the ball.
Q:What does "S" mean by ball valve Q11S?
S stands for plastic sealing.Stainless steel ball valves only need to rotate 90 degrees of operation and small rotating torque can be closed tight. Full equality of the valve cavity for the media to provide a small resistance, through the flow channel.The main features of the valve itself is compact, easy operation and maintenance, stainless steel ball valve can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow.Ball valve body can be integrated, or can be combination.This kind of valve should be installed horizontally in the pipeline.Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve.Stainless steel ball valve is divided into 304316321 stainless steel ball valve.
Q:What are the differences and advantages between O ball valve and V ball valve?
Quality solutionsO type ball valve with floating or fixed type design, the relative movement of the parts are made of small friction coefficient of self-lubricating material, so the operating torque is small, in addition to the long-term sealing and sealing grease, making the operation more flexible, its advantages are as follows:1, fluid resistance is smallGeneral valve diameter and diameter shrinkage of two kinds of structure, no matter what kind of structure, valve flow resistance coefficient are relatively small. The conventional ball valve for the straight through, also called full flow type ball valve, channel diameter is equal to pipe diameter, friction resistance loss is only the same length of pipe. All valves, this valve fluid minimum resistance. There are two ways to reduce the resistance of pipeline system: one is to reduce fluid flow, is to increase the diameter and the valve diameter, it will greatly increase the cost of the system. The two line is the local resistance reducing valve, ball valve is the best choice.
Q:Domestic water pipe ball valve or cut-off valve?
So, in the regular switch to the place, with the ball valve convenient, in the need to adjust the flow of the place and do not need to switch regularly, with a good cut-off valve.
Q:What does copper ball valve type Q11F-16T mean?
Q11F-16T refers to the internal thread of copper ball valves, 16 kg pressureQ refers to the ball body; 1 refers to the internal thread connection; 1 refers to the straight through; F refers to PTFE sealing cover; 16 refers to 16 kilograms of pressure; T is the valve body material is copper material, and then add, the front two also answered very specific.
Q:Is the ball valve switch in front of the water meter or after the water meter?
The specification, both before and after the water meter valve; if the drawings will one, that is the water front, if the two valve that is behind the water meter,
Q:What do you mean by ball valves dn20pn1.6rf?
DN20 caliber is 20mmPN is the pressure grade, usually PN16, 1.6MPa classRF convex flange connectionYour side should be similar to the Q41F-16 model of this type of ball valve
Q:Are ordinary ball valves standard?
DN20, standard parts are produced according to the national standard size, you say ordinary ball valve, if it is according to the standard size is standard
Q:Structure design principle of fire ball valve
The fire ball is fixed ball structure, the upper end of the main seal seal, the seal has the function of DBB, in good condition, the valve in the fully open or fully closed state, the cavity in the outfall or vent to observe the upstream seat leaks. Pipeline ball valve in normal use, the middle chamber without pressure. In the case of fire accidents, a reasonable design of the fire protection structure of the valve seat can slow down the progress of the upstream pressure medium into the middle cavity, and avoid the leakage and leakage of the medium caused by the boosting of the middle cavity. The valve seat with good fire protection design is an active measure to ensure the safety and fire resistance of the pipeline ball valve.The fireproof structure design, the design of the seat structure fire is the key, the seat of the fire performance is good, in the fire accident condition, fire structure design of the pressure between the body and the stem structure, reduce the fire around the body.
