Q:What is the electric butterfly valve? Please, great God!
ZSDF type fire signal butterfly valve uses: top of the ZSDF type fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center.
Q:What's the size of the signal butterfly valve sleeve?
The signal valve of the fire door (not in the signal valve shutter doors, fire signal valve use: top fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center. Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system.
Q:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
Q:How warm is the PTFE butterfly valve?
Ordinary PTFE clip butterfly valve normal temperature tolerance of about 120 degrees, instantly to about 150 degrees
Q:What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?
Valve carbon steel -16c body 316 stainless steel -16r
Q:Seat Leon Cupra 1.8T Mk1. Is my seat fitted with a dump valve as standard.?
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:how to get a valve out of combustion chamber?
Your going to have to pull the heads.
Q:What does the model D373H-16C of butterfly valve mean?
For example: Z543H-16C bevel gear flange plate valve, nominal pressure 1.6MPa, the valve body is made of carbon steel valves valve name according to the mode of transmission, connection form, structure, lining material and type name. But here in the name of the content shall be omitted: (1) the connection form: "flange" (2. Structure: a): valve "rod" and "flexible" and "rigid" and "single gate"; B: "straight" stop valve and throttle valve; C: ball "floating" and "one-stop"; D: butterfly valve "vertical plate type"; E: the diaphragm valve "roof"; F: Cock "filler" and "one-stop"; G: check the "one-stop" and "single"; H: "safety valve is not closed. (3) the valve seat sealing surface material in the material name Said. I have just engaged in the valve industry, mainly to do www.ssfmsh.com traps, but also hope that we learn from each other and make progress together
Q:Where is the pcv valve in a 2001 ford focus?
Its on the front of a line that looks like a big black t and it is very hard to notice.
Q:What's the material of the butterfly valve seat?
Butterfly valve seat materials commonly used include EPDM (three yuan ethylene propylene rubber), NBR (Ding Qing rubber), PTFE (PTFE), metal sealing (cemented carbide).Their scope of application is..:1, EPDM (three yuan ethylene propylene rubber): excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor, color stability, electrical properties, oil and gas flow at room temperature. Ethylene propylene rubber products can be used at 120 degrees for a long time and can be used briefly or intermittently at 150-200 degrees centigrade.2, NBR (Ding Qing rubber): from butadiene and acrylonitrile was prepared by emulsion polymerization, nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are poor resistance to low temperature, poor ozone resistance, poor electrical properties, and slightly lower elasticity.3, PTFE (polytetrafluoroethylene): can be used at 260 degrees for continuous use, with the highest use temperature of 290-320 degrees, low coefficient of friction, good wear resistance, and excellent chemical stability. It can not be injection molded and can be extruded or painted. PTFE's unique properties make it widely used in chemical, petroleum, textile, food, paper making, medical, electronic and mechanical industries and marine operations.4, metal seal (hard alloy): metal seal valve seat material has good resistance to high temperature, high pressure resistance, corrosion resistance and wear resistance, but the high requirements of the processing technology, the biggest drawback is the long time operation is easy to generate leakage.
