Q:Butterfly valve use
Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve. Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe
Q:Valve cover gasket replacement?
Hi Make sure your PVC valve it clear. That puts pressure inside the engine and makes the leaks. If it is plugged just tighten the valve covers might work.
Q:The difference between butterfly valve and gate valve
Butterfly valve role, butterfly valve is used to open and close disk type reciprocating rotation of about 90 degrees to open, close or adjust the flow of a 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.
Q:What's the use of fire butterfly valve?
You should ask the signal butterfly valve, butterfly valve in the fire signal system which is a monitoring alarm signal, its purpose is to ensure that the valve has been opened in the daily state, to prevent misuse operation was closed, thus affecting when accidental fire extinguishing. Therefore, it is necessary to set up the signal valve!
Q:Old Thompson Aircraft Engine Valve, help dating?
Wow Hannah! That's a cool find for sure! It appears to be possibly a valve for a radial aircraft engine as it looks very similar to ones i've seen used in Pratt+Whitney R3350's etc. It looks like it could probably date to the 1940's up thru the 1950's. Look for a Part Number stamped on the valve or on the box. After WW2 there were all kinds of manufacturers making parts for airplanes. Many were gobbled up by competitors, converted to manufacturing other products or went out of business altogether. However, a few did hang on....and I think this may be what has become of Thompson Aircraft today.... Thompson Aerospace, Inc 22431 Antonio Parkway B160-102 Rcho Sta Marg, CA 92688-2804
Q:What does "D341X-16Q" mean?What do D341-16Q letters and numbers mean for butterfly valves?
D - valve type code: Butterfly valve;3 - valve drive mode code: worm gear;4 - valve connection form code: flange;1 - valve structure type code: vertical plate type;X - seat sealing surface or lining material code: rubber;16 - nominal pressure value: PN1.6MPa;Q - body material code: QT400 - 15.
Q:How do you draw the butterfly valve in the engineering drawing?
Butterfly valve there are many kinds of painting, according to the design institute out of the icon, below we together to understand the icon, which has the butterfly drawing.
Q:What are the butterfly valves models?
Divided by connection:1 pairs of clip butterfly valveThe butterfly plate of the clip butterfly valve is installed in the direction of the diameter of the pipe. The valve is fully open.The clip butterfly valve is simple in structure, small in size and light in weight. Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.2, flange butterfly valveThe flange butterfly valve is a vertical plate structure, and the stem is a sealing ring of an integral metal hard sealing valveFor flexible graphite plate and stainless steel plate composite structure, mounted on the valve body, butterfly plate sealing surface of stainless steel surfacing. The sealing ring of the soft sealing valve is made of nitrile rubber and is mounted on the butterfly plate.3, lug butterfly valve4 、 welded butterfly valveWelding type butterfly valve is a non sealed butterfly valve, widely used in medium temperature less than building materials, metallurgy and mining, electric power production process at 300 nominal pressure 0.1Mpa pipe, used to open and close connected, or adjust the medium quality.
Q:The difference between the directly buried gate and the flange valve and butterfly valve
Buried gate also called buried gate valve, valve can be directly buried underground, built without manhole, reduce road excavation area; small well maintained road and beautiful room can reduce the difficulty of construction, reduce project cost. The directly buried soft sealing gate valve is divided into two types: telescopic type and fine fixing type, wherein, the telescopic type is divided into metal type and plastic type. In the process of construction, the telescopic type can be adjusted arbitrarily according to the distance between the buried depth of the valve and the ground, and the micro adjustment can be adjusted on the spot. The directly buried gate valve has the advantages of long-term use, no leakage, no maintenance, etc., and can effectively avoid other people switching the valve and stealing the manhole cover at will.Flange gate valve is connected to the flange gate valve, this connection is the most common way. The flange gate valve is stable and reliable when used in the pipeline, so the flange gate valve is used on the high pressure pipeline.Butterfly valve refers to the closure of parts (valve or butterfly plate) as 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.
Q:What are the advantages of butterfly valves?
Butterfly valve, also known as shutter valve, its advantages are:A. has a large circulation capacity and is about 1.2 times the same size as two seat valves;
