- Q:How to connect the signal butterfly valve?
- If you mean the signal of fire water supply system, there are generally three outlets, one public, one open and one off. Fire control system signal butterfly valve is normally open, so the signal butterfly valve to open position, with a multimeter to measure the 2 lines, the 2 lines into the input module is fine.
- Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
- Our factory butterfly valve has two-way sealing, can be installed, and will not leak. If there is an arrow above the butterfly valve is one-way seal, that is, can not be installed. One way sealing will cause leakage. If you have any other questions, you can bring them up. Let me help you with that
- Q:i have a slightly small mitral valve leak in my heart. my cardiologist say nothing to worry about, but i am not sure. can some one explain if it would eventually lead to some complications?
- Mitral valve prolapse is the most common cardiac problem and may affect five to twenty percent of the population. The condition is most common in women, although men are also affected. With MVP, symptoms do not begin before the early teenage years (approximately age 14 in girls and 15 in boys), but adults of any age may be affected. MVP tends to run in families, so those with blood relatives with MVP have a greater chance of also having the condition. If a person has mild MVP, he/she needs no restriction of exercise. But if the MVP is big, then it is a different thing. Because, though complications in this condition are very less, people who suffer from this condition have to take extreme care. In case of large MVP, you may have to cut down on your physical activity, have a surgery and may be put you on medications like beta blockers. If the valve is truly defective (not just 'prolapsed'), it is serious. Unfortunately, doctors have mistaken a 'differently shaped' mitral valve as a disease in itself. And this is where the non-disease comes in. In simple terms, a mitral valve that appears prolapsed is usually normal. It still is not clear to experts why some mitral valves appear prolapsed and allow some blood leakage backwards. I have an answer for that phenomenon, but the important point is that the disease is a non-disease.
- Q:Butterfly valve structure and working principle
- Butterfly valve structure: Center to clip butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve
- Q:What kinds of butterfly valves are available? What is the working principle of butterfly valves?
- According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.Divided by work pressure:(1) vacuum butterfly valve. Working pressure is lower than the standard atmospheric pressure butterfly valve.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.
- Q:What's the material of the butterfly valve seat?
- Tianjin saide valve limited company can provide all kinds of valve seat material for the majority of users: white food gum X1 - X2 - X3 - Hypa EPDM rubber X4 rubber X5 - resistant rubber X6 - fluorine rubber X7 - heat resistant ethylene propylene rubber X9 silicone rubber and PTFE F4.
- Q:That industry uses most of the butterfly valve, and only use the butterfly valve, a large number of use of butterfly valve, seek expert advice!
- See what kind of butterfly valve: 1., the use of all metal, mainly in the chemical industry.2. large diameter butterfly valve, mainly in low pressure water pipes and wind pipes3 environmental protection water treatment factory with more butterfly valve.
- Q:Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- D--- stands for butterfly valves; 4--- refers to the form of flange connections; 1--- refers to the valve stem and disc in the center of the valve line, without eccentricity; w--- refers to the valve seat material and body material is the same, usually carbon steel. The final 1--- refers to the nominal pressure of 1 kg / cm2.
- Q:1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.
- do mean you have an area in house that the heat isnt working in? if so try by passing the thermostat zone valve is that same as circulator pump its valve in the line to radiator usually near boiler has wires onit that go to thermostat should be a circulator pump for each thermostat
- Q:Do you use the straight stem butterfly valve in the fire fighting engineering?
- Only the gate valve clearly rod and dark pole, butterfly valve classification is the clamp type and flange type, Zhengzhou butterfly valve factory, Mr. Zhao
