Q:Ball valve leakage of this place, how do?
The seal on the valve body is broken. Screw it down and change the gasket
Q:All inclusive ball valve and half a bag of the difference between the ball, mainly new manual ball valve
The ball valve is defined with the ppR/PE hot melt plastic pipe connected with the ball valve hot melt connection, ordinary ball valves generally use the threaded connection or flange connection.Hot melt connection is widely used in PB pipe, PE-RT pipe and other new pipe connections.Hot melt connection has the advantages of simple connection, long service life and easy corrosion.PPR pipes can only be connected by hot melt. There is a dedicated connection PPR tube double union copper ball valve, ball valve is full of copper, on both sides with PPR live tab.Ball valve (in the field of marine engineering and ships should be cut-off valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve to rotate the valve movement.". Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.Ball valve was introduced in 1950s, with the rapid development of science and technology, production process and product structure of continuous improvement, in a short span of 40 years, has rapidly developed into a major valve category. In western developed countries, the use of ball valves is increasing year by year.
Q:What are the differences between the lever ball valve and the handwheel ball valve? What are their differences?
Group pairs of valves, have not heard of a lever type ball valve, only lever type safety valve, hand wheel type is only the way it drives different, the way is also ever-changing, to see the needs of individuals
Q:Calculation formula of ball valve flow
The sectional area of diameter of DN15, DN25 and DN50 is respectively:DN15:15*3.14/4=176.625 mm, 0.0177 square decimeter.DN25:25*3.14/4=490.625 mm, 0.0491 square decimeter.DN50:50*3.14/4=1962.5 mm, 0.1963 square decimeter.A pipe flow rate of V=4 M / s V=40 decimeter / s, and the 1 liter =1 cubic meter, the pipe flow respectively (cross-sectional area multiplied by the velocity):DN15 pipe: flow Q=0.0177*40=0.708 L / sec,It's 2.55 cubic meters per hour.DN25 pipe: flow Q=0.0491*40=1.964 L / sec,It's 7.07 cubic meters per hour.DN50 pipe: flow Q=0.1963*40=7.852 L / sec,It's 28.27 cubic meters per hour.Note: a flow rate must be given to calculate the flow rate, which is calculated in accordance with 4 meters per second. Reference: http://zhidao.baidu.com/question/77687541.html answer: good night dream | six | 2010-5-24 22:46It's 600 cubic meters / hour!Flow Q=600 m3 / h = 0.167m^3/sThe flow rate is V=4Q/ (3.1416D^2) = 4*0.167/ (3.1416*0.090^2) = 26.25 m/s, and the flow velocity is very large!It could be 600 cubic meters per day:Flow rate Q=600 m3 / day = 0.00694 m^3/sFlow rate V=4Q/ (3.1416D^2) = 4*0.00694/ (3.1416*0.090^2) = 1.09 m/s flow rate is normal.
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:Ball valve, PTFE pad inappropriate choice, is not easy to bad ah?
PTFE gasket is mainly resistant to high temperature, easy aging, but the use of such soft sealing gasket, ball valve sealing performance.
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 does copper ball valve mean by "1/2"?
1/2 is inch inch, which is what is usually called "valve", and the caliber is "DN15". You can see the contrast chart of the valve diameter and inch.
Q:Gate valve, ball valve, the difference between the pressure regulating valve
To this end, the media from below to enter the way, generally only applicable to small caliber manual stop valve, to the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way. The disadvantage of the medium entering from the top is just the opposite of the way it is entered below. Compared with the gate valve, the utility model has the advantages of simple structure, good sealing performance, and convenient manufacture and maintenance. The disadvantage is that the liquid resistance is large, and the opening and closing force is large. Gate and globe valves are fully open closed type valve, cut off or connected as the medium use, not as a control valve. The range of application of stop valves and gate valves is determined by their characteristics. In the smaller passages, the cut-off valve is used when required for better shutoff; in the steam pipe and the large diameter water supply pipe, the gate valve is generally used because of less fluid resistance.
Q:What does "DN PN" mean?
PN nominal pressure.Definition:Relating to the mechanical and dimensional characteristics of the components of the piping system and the identification of letters and combinations of numbers for reference. It consists of letters PN and followed by dimensionless numbers.Note 1: numbers followed by letters "PN" do not represent measurements and are not used for purposes of calculation unless otherwise specified in the relevant standards.Note 2: is not associated with the relevant pipe component standards, but the term "PN" does not make sense.Note the 3: piping element allows the pressure to depend on the PN value of the element, the material and design, and allows the operating temperature, etc., to allow the pressure to be given in the corresponding standard pressure temperature class table.Note 4: all pipe elements with the same PN and DN values shall have the same mating dimensions as their flanges.The latest definition of PN comes from standard GB/T 1048-2005, the definition and selection of pipe component PN (nominal pressure), and is referenced in the standard of pipe fittings and tubing. GB/T 1048-2005 7268:1996 Pipe components - modified ISO/CD Definition of nominal pressure, a "note increase than the original standard: allow numerical" choose other PN when necessary, namely in the PN series, you can use other numerical PN.
