- Q:I have put a new pressure valve and replaced both thermostat
- If you have replaced the TP valve, more than likely there is a heating element shorted to the tank. This will cause continuous heating and high temp/high pressure...good luck.
- Q:How does the pneumatic butterfly valve control the angle of opening?
- This is really not good, control seems to be pneumatic defects, can only rely on the feeling
- Q:What does the butterfly valve D361H - 25C DN350 mean?
- Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM
- Q:Water supply pipe gate valve and butterfly valve which good?
- 2. ball valve: ball valve with a central opening of the ball as the valve heart, the rotation of the ball control valve opening and closing. The ball valve has the advantages of simple structure, light weight compared with the cut-off valve, the sealing surface has the advantages of simple structure, easy processing, good sealing performance, convenient operation, switch quickly, but can not be used to adjust the flow, suitable for high pressure (up to 320 psig) pipeline, at present, the packing material limit, can only be used for 200 DEG C, can also be used a variety of media and the viscosity of the suspension.3. butterfly valve: butterfly valve, also known as turn over plate valve, is a simple structure of the valve. As butterfly valve should not be closely matched with the pipe wall, only applicable to regulating flow, can not be used to cut off the pipeline, often used in conveying air and flue gas pipe to regulate flow. Butterfly valve is with the stem rotation of the circular butterfly plate for headstock parts, in order to achieve the opening and closing action of the valve. Butterfly valve is mainly used with shut-off valve, can also be designed to adjust or cut off and adjust the function. At present, butterfly valves are used more and more in low pressure medium and large diameter pipelines.
- Q:Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.
- Give you the address bar, this is a three-dimensional CAD model library of an online version of the real registered mail, free of charge, there are hundreds of Chinese and foreign manufacturers of the product model is available for download, such as ABB, SMC, FESTO, AIRTAC, CAMOZZI, MISUMI etc..
- Q:How is the lug butterfly valve connected to the flange?
- When installing, pay attention to the butterfly plate. The sealing ring between the flange face and the butterfly valve is tightened. After clamping, it can be tightened.
- 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.
- You may have only one circulate pump on the boiler. If you want to check the zone valve there is a small handle on the valve you can lift up and this will open the valve manually. It will be found on the (usually) green valve on the return end of the copper pipe. It should have a red and white wire attached. If this is opened manually and you get heat you can replace the top half of the valve by twisting it off and exchanging it with a new one. I think they are around $35.00 bucks or so at Home depot. You can keep it open without and fear. This means you will only have a one zone boiler and all baseboard s will get heat instaed of being zoned
- Q:Butterfly valve in the use of the difference? Caliber?
- Role of butterfly valveButterfly valve is to use disc type to open and close parts reciprocating reciprocating about 90 degrees to open, close or adjust the flow of medium valve. The butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, the driving performance of torque is small, simple operation, rapid, high chemical corrosion, and can also have good flow control function and closure characteristics, the use of butterfly valve is very extensive. Its varieties and quantities are still expanding, and the development of high temperature, high pressure, large caliber, high sealing, long life, excellent regulation, as well as multi-function development of one valve. Its reliability and other performance indicators have reached a high level. Disadvantages, there is a certain resistance to the medium.Gate valves are more used in steam pipes and large diameter water supply pipelines, because of the general requirements of fluid resistance is small, the use of gate valve.Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open. Need a higher installation space, the valve sealing surface has a certain self sealing capacity, its spool by the media pressure closely with the valve seat sealing surface contact, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
- Q:Butterfly valve is generally used in what position?
- Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, environmental protection, chemical smelting and power building water supply and drainage engineering system in conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow. It can also be used for switch control of low pressure pipeline medium.
- Q:Which is better, the round two lobe butterfly valve?
- Round type double butterfly butterfly valve is the first choice of Shanghai Machinery & Equipment Co., Ltd., the company is a professional design, manufacture and sale of central air-conditioning products at the end.
