Q:Principle of forced sealing ball valve
With spring to achieve forced sealing, not applicable to high pressure
Q:Advantages and disadvantages of electromagnetic valve and electric ball valve
I think you should use the solenoid valve is diaphragm type, and not particularly good products, diaphragm solenoid valve in the closed position when the diaphragm is easy to change, resulting in pipe die, or medium impurities caused the pilot hole is blocked, the valve will not move, so the diaphragm solenoid valve. Is there a film guide card member, so that each position of the diaphragm in the correct position, but the pilot hole is not a solution, of course, you can use direct action solenoid valve, such problems are solved. The electric ball valve than the pilot solenoid valve in this respect, but the cost of this fear is much higher, especially the pipe diameter is not so, it does not pay!
Q:What does the RTFE say in the ball valve?
RTFE reinforced PTFE is more wearable than PTFETeflon PTFEThe seat of tetrafluoroethylene specified for a temperature range of ~200 DEG C -32. High temperature resistance and chemical resistance. Because of its high density and good permeability, PTFE can also prevent the corrosion of most chemical media.Conductive PTFE is an improved PTFE product that allows the current to pass through the lining and thereby cancel the insulation properties of ptfe. Because of its conductivity, conductive PTFE can not be checked by edm.+ reinforced PTFE RTFERTFE is a modification of PTFE material. Pure PTFE although very low coefficient of friction (0.02~0.04) but the wear volume is great, but also because of its easy creep, poor mechanical properties, low bearing capacity, poor dimensional stability characteristics such as friction material has great localization. Only modified by compound method to meet the special requirements of all walks of life sealing material on the wear resistance, to improve the wear resistance of PTFE, can be incorporated into some wear-resistant materials such as glass fiber, carbon fiber, graphite, molybdenum disulfide, bronze powder and some organic compounds, making them reticular junction formed in the PTFE layered structure so as to improve the the stiffness, thermal conductivity, creep resistance, and greatly improve the wear resistance.PTFE is composed of tetrafluoroethylene monomer polymerization of the polymer, the wax is similar to a PE transparent or opaque, its density is 2.2g/cm3, the water absorption rate of less than 0.01%. Its chemical structure is similar to that of PE, except that all hydrogen atoms in polyethylene are replaced by fluorine atoms. Because the C-F bond is high and stable in performance, it has excellent chemical resistance
Q:DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
In addition to the three common, flange standard complex, a long story.All kinds of standards, there is a little difference in thickness, diameter of flange, bolt hole number, but the flange bolt hole parameters of the same pressure level (bolt circle diameter K, bolt diameter L, bolt number N) are the same.
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:What's the difference between a one piece ball valve and a two piece ball valve?
A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
Q:Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?
Full diameter ball valve flow resistance is minimal, the flow resistance of the globe valve is large
Q:What are the types of vacuum ball valves?
The utility model can be used in the high vacuum condition and can be used under the low voltage system, and the advantages of positive and negative pressure are same
Q:What is the specific difference between floating ball valve and fixed ball valve?
Floating ball valves and fixed ball valves can be located in the lower stem position, if there is a lower stem is fixed ball valve
Q:Advantages of track ball valves
10, the valve refractory design, API, 6FA and API 607 standards. All valves are fire resistant and safe.The valve seat sealing surface., all metal seal structure, when the fire, still can guarantee the sealing medium leakage, stop.The flange. In stainless steel and graphite gasket, can meet the requirements of fire;The stuffing box is arranged. Flexible graphite packing, can lose the effect due to fire and other reasons in other packing flexible graphite packing to seal effect can meet the requirements of fire;11, the valve stem through the stem nut, valve cover, valve body, between the core of the ball formed a continuous circuit conduction, to achieve anti-static effect.12, in order to improve the reliability of the valve, safety and sealing capacity, to reduce the failure rate, the valve low-pressure air tightness does not depend on the seat spring to achieve.13, the stem and valve ball position by stem guide pin and stem to cut off the coordination to control, in order to ensure the stability of valve operation, stem guide pin for double guide pin, and stem guide pin can be removed and replaced from the outside.14, hand wheel or bearing fixed, use bolt or nut compression, do not use elastic clasp.15, the valve installation size and the existing valve consistent, with good interchangeability.
