Q:What are the differences and advantages between O ball valve and V ball valve?
5, high reliability1, the ball and valve seat a pair of sealing pairs, there will be no abrasions, rapid friction and other failures;2, stem into the built-in type, to eliminate the stem under the action of fluid pressure may be caused by the packing gland release flying accident hidden trouble;3 、 adopt antistatic and fireproof structure ball valve, which can be used to transport petroleum, natural gas and gas pipelinesV type ball valve structure of a right angle turn, can achieve flow regulation, according to the V type angle V type sphere, realize different proportions, V type ball valve and valve actuator and positioner supporting the use, the ratio can be adjusted V type valve adjustment for a variety of occasions, with a rated flow coefficient large, adjustable ratio, good sealing effect, regulate the performance of zero sensitivity, small size, can be vertical horizontal installation. For control of gas, steam and liquid medium.V type ball valve for rotary type rectangular structure by V type valve, pneumatic actuator, positioner and other accessories; there is a similar more than 100 of the inherent flow characteristics; dual bearing structure, the starting torque is small, with excellent sensitivity and speed sensors, the shear capacity of strong.
Q:1 and 1/2 ball valve is how much?
1 and 1/2 ball valves, 1 and 1/2 are the international imperial units of length, which refer to the length, length, or size of the valve through the bore, approximately 38.1mm
Q:What is the meaning of ball valve model Q947MF-2.5C?
Q stands for ball valves, 9 for electric installations, 4 for flange connections, 7 for straight through runners, 2.5 for 2.5 kg pressure, and C for carbon steel for valve bodies,
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:Under what circumstances with the butterfly valve, under what circumstances with the ball valve?
Selection principle of ball valve:1, oil, natural gas transmission mains, need to clean the pipeline, and be buried in the ground, all pass by, the ball valve full welded structure; buried in the ground, select all pass through ball valve welded connection or flange connection; pipe flange connection, welding, selection of connection, all pass through or shrink the diameter of the ball valve.2, product oil pipeline and storage equipment, choose flange connected ball valve.3, the city gas and natural gas pipeline, choose flange connection and internal thread of the floating ball valve.1 、 in the oxygen piping system of the metallurgical system, the fixed ball ball valve should be selected after the strict degreasing treatment and the flange connection.2, low temperature medium piping system and device, should choose to use the valve cover of low temperature ball valve.3 、 the lifting rod type ball valve can be used on the pipeline system of the catalytic cracking unit of the oil refining unit.4, chemical systems such as acid and alkali corrosive media and piping systems, it is appropriate to choose austenitic stainless steel, PTFE seat sealing ring for all stainless steel ball valve.5 、 metal to metal sealing ball valve can be used in metallurgy system, power system, petrochemical equipment, piping system or device of high temperature medium in city heating system. 6, the need for flow regulation, you can choose the worm gear drive, pneumatic or electric with V shaped opening of the regulating valve.
Q:Who knows why the ball valve is divided into a piece of ball valve, two pieces of ball valve, three pieces of ball
There is, of course, a difference,This is according to the structure of the valve body,The difference between them is whether they are easy to disassemble, for example, the three piece of ball valve is easiest to disassemble.
Q:What type of ball valve is Q17F-10T?
Q is ball valve, 1 is internal thread, 7 is fixed ball through type, F is PTFE plastic seal, 10 is pressure 1.0MPa, and T is copper or copper alloy body.
Q:Advantages and disadvantages of ball valves and scope of application?
Ball valve and valve are generally used for fluid switching and flow, usually can not be used for flow regulation, and in addition to the valve can be used for fluid switching and cut-off, can also be used for flow regulation. If you need to adjust the flow rate, it is better to use the medium valve. The valve operation is very convenient, rapid and labor-saving, generally as long as the valve handle can turn 90 degrees, and the ball can be used not too pure (solid particles) fluid because of its spherical valve core of the fluid in the opening and closing of the shear movement. The gate seal between easy to cause erosion and abrasions, maintenance more difficult, larger size, open need a certain space, opening and closing time is long, complex structure.As you say, the ball valve is generally used for small caliber, because small caliber production is simple, relatively inexpensive, caliber increased production accuracy requirements, production costs increased, so the price will be high. Generally small diameter threaded connections, from the G1/4~G2 have.
Q:What's the difference between T ball valve and L ball valve?
This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.
Q:What is the difference between ball valve and butterfly valve?
The butterfly valve consists of valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; and the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the sealing performance of the ball valve than the butterfly valve; butterfly valve structure is relatively simple, generally with low pressure valve, high pressure valve can reach 64 kg. The ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.Butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric, three eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg; the valve can also be divided into soft seal and seal, soft seal valve maximum temperature is below 280 degrees, the pressure is on 64 kg, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms. Shanghai Sino US valve for your answer, for reference.
