- Q:I have put a new pressure valve and replaced both thermostat
- so that should have fixed it I wonder if you needed to replace the stats
- 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?
- I have Mitral Valve Prolapse, and slight regurgitation. If your cardiologist says not to worry, I wouldn't worry. Mitral Valve prolapse just means you have a slight deformity of the bicuspid valve. It doesn't close correctly. It's not a disease, or anything like that, just a slight deformity. The symptoms are annoying. You may or may not have palpitations, slight sharp chest pain sometimes, dizziness, fatigue, and anxiety from it. You must have it checked yearly to make sure it's not progressing. I have had it since I was born, and now I am 28, and it has not progressed at all. MILLIONS of people are walking around with it, and don't even know it. It's not really a big deal. However, it does have the potential to worsen and you may or may not need a new valve. But that normally happens when you're older, in your 50's or up. Don't worry about it.
- Q:What does the model D373H-16C of butterfly valve mean?
- D373H-16C said: D type butterfly valve butterfly valve 3 said, said 7 of the turbine, said clip, 3 said the three eccentric (swash plate), 16 C nominal pressure, said carbon steel. In fact, if you want to understand this, to understand the valve 3.07ghz, later met have to be attached to the valve. 3.07ghzModel for valves, valve number indicates valve type valve should normally be that type, drive type, connection type, structural features, nominal pressure, sealing surface material, body material and other factors. Standardization of the valve type of valve design, selection, distribution, provide more convenient. The type of valve types and materials are more and more more models of the preparation of the valve will become more and more complicated. Although the preparation of our valve type unified standard, but gradually can not meet the needs of the valve industry. At present, the valve manufacturer usually adopt a unified numbering; not uniform numbering, the manufacturer can make out no.methods according to their own situation. Unit two unit three unit four unit five unit six unit seven unit
- Q:What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?
- Avoid friction and wear on the sealing surface!And, at the time of closing, and opening the opposite, there is a better sealing effect! Now generally use eccentric butterfly valve as the main. That's all I know! If there is any mistake, please forgive me!
- Q:What's the difference between an electric two position control valve and an electric butterfly valve?
- The electric butterfly valve belongs to a kind of electric valve and electric control valve. The main connection modes of electric butterfly valve are flange type and clip type. The main forms of electric butterfly valve are rubber seal and metal seal. The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as the shut-off valve, control valve and check valve of the piping system.
- Q:What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?
- Double eccentric butterfly valve: in the single eccentric butterfly valve on the basis of further improvement of forming, is the most widely used double eccentric butterfly valve. The structure features that the center of the stem deviates from the center of the disc as well as the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life.
- Q:In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?
- Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
- Q:What does butterfly valve do?
- [1] butterfly valve is also known as turn over plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control.[2] butterfly valve: butterfly valve refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow. Butterfly valve categories are: handle butterfly valve, turbine butterfly valve, pneumatic butterfly valve, electric butterfly valve and so on.
- Q:i was changing valve seals and two dropped i can see the head of the valve but a magnet wont pull them up i put air the spark plug hole too but no luck 1985 ford bronco II
- Your going to have to pull the heads.
