- Q:Seat has said to the previous owner that the car needs a new air mass meter and dump valve.I am putting a new air mass meter on it.Does it have a dump valve.I know very little on this subject.
- every turbo will have a dump valve(waste gate) to regulate the boost to the engine Dump valves are fitted to the engines of turbo charged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pressurize air, but the closed throttle prevents the compressed air from entering the engine. In this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere. Even with a dump valve the compressed air acts as a brake on the turbo (slowing it down), because the pressure on the backside of the turbo is at a higher pressure than on the front side (and the air actually wants to flow through the turbo backwards). A blowoff valve is a more elegant solution to this problem by allowing the turbo to freewheel when the throttle is closed (equalizing the pressure on both sides of the turbo). Unlike a dump valve a blowoff valve can be used at multiple boost settings without reconfiguration. Blowoff valves are sometimes incorrectly called dump valves because they serve a similar function, but they are very different solutions to the same problem.
- 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:Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.
- Support many 3D CAD format, such as the commonly used UG, Pro/E, SolidWorks......As for the butterfly you said, don't post the link up, the standard JIS, American Standard ANSI, German standard DIN are.You use Baidu Search "LinkAble PARTcommunity", after the open registration, CAD format, such as UG, ASAHI and then to find the manufacturer home page, which is the valve, you said the Japanese standard, German standard, American Standard valve basically all.
- Q:For example, the arrow above is from left to right, and the direction of my current is from right to left. Is that ok? I have a diameter of 700 of the hard seal butterfly valve is so installed, but it will leak water, it will not leak, very serious
- From the above example, it can be concluded that the arrow direction of the butterfly valve body refers to the direction of the pressure of the medium. Before the installation, the user must know the direction of the pressure of the valve after the valve is closed. The direction of the arrow of the free valve body is in accordance with the direction of the pressure of the medium, so that the correct use can be achieved, and the tightness of the valve body is kept in good condition.
- 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:What is the meaning of American Standard butterfly valve B series
- American Standard flange connection is divided into A, B series. A series for normal flanges, B series for compact flanges. 24 "to no AB series, flange standards for B16.5, 24" above B16.47.
- Q:Why anti condensation of aluminum alloy anti condensation butterfly valve?
- Anti condensation butterfly valve principle: the use of the high performance plate material, can effectively prevent the temperature of body parts, isolating the transfer medium in the pipeline, to the actuator and the connecting flange surface without dew.
- Q:Model specification for butterfly valves
- Butterfly valve type to clip type:D7A1XR-16 50mm-1200mm D7A1XD-16 50mm-1200mm D7A1XN-16 50mm-1200mm D7A1FR-16 50mm-1200mm D7A1FD-16 50mm-1200mm D7A1FN-16 50mm-1200mm 偏心式 ：D73F-16 50mm-300mm
- Q:What's the difference between the three eccentric butterfly valve and the two 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. Three eccentric butterfly valve: to high temperature, must use hard seal, but the leakage is large; to zero leakage, must use soft sealing, but not high temperature. In order to overcome the double eccentric butterfly valve this contradiction, and the butterfly valve for third times eccentric. The so-called third eccentric, that is, the shape of the sealing pair is not a positive cone, but rather oblique cone.
- Q:Water supply pipe gate valve and butterfly valve which good?
- 1. gate valve: also known as gate valve or gate, there is a valve in the valve flow direction perpendicular to the medium, adjust the height of the gate, you can adjust the flow of fluid. Valve advantages are small resistance, close tight, no water hammer phenomenon, widely used in a variety of liquid and gas shut-off valve. It also has some adjustment function, but when the part is opened, the gate is easy to be wetted by the fluid. When the fluid flows, it causes the shaking of the alarm board and the sealing surface is easy to wear. The drawback of the gate valve is that the structure is complex, the price is more expensive, it is difficult to repair, and the solid material is easy to deposit in the valve seat groove. Therefore, it is not suitable for the pipeline containing fiber or solid material in the fluid. Commonly used in the air, steam, oil medium pipeline, but also used as vent valve and low silk system valve.Gate valve is commonly used as one of the cut-off valve, mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Valve is suitable for pressure, temperature and caliber range, especially for medium and large diameter pipes.
