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: How do you explain A in butterfly valve D37A1?
Represents a seal or lining material symbol.Said sealing ring or lining material with the Chinese phonetic alphabet: B Babbitts D nitrided steel, acid resistant stainless steel H, J L Aluminum Alloy, hard rubber, nylon NL, P leather, SA PTFE, SC PVC, SD bakelite, T copper, TC enamel, X rubber, Y hard alloy
Q: How can I get the fire signal butterfly valve?
1, the signal butterfly drive by the worm gear drive shaft and butterfly plate rotation, realize the opening and closing and control flow. 2, rotating the handwheel worm gear to the disc to open and close and adjust the flow to the handwheel clockwise rotation for the valve closed. 3, worm gear is arranged in the box body micro switch has two forms: A, in the gear box body is provided with open and close direction two microswitches, respectively, when the valve fully open and close action, connected to the control room "valve open" valve off "light source, the quasi it shows the state of the valve switch. B, in the driving device is arranged in the box body the microswitch (disc position close to 0 degrees), when the butterfly plate from 0 degrees to 40 degrees when the position of a micro switch, the output valve closed signal, 40 degrees to 90 degrees when the position of another pair of normally closed output valve opening signal. A cam that adjusts the touch microswitch and shows the different positions of the disc.
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.
Q: Fire, the signal butterfly valve flange connection or welding?
Fire signal butterfly valve is generally used to clamp type connection more, the clip type butterfly valve body is without flange, that is to say, with two flanges on the pipe, then screw the butterfly valve. Followed by the butterfly valve itself with flanges, and then the pipe flange with screws connected, this is the flange connection. Fire welding less use, pressure is not high!
Q: Function of signal butterfly valve in fire sprinkler system
The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
Q: Specifically an engine valve retainer.
Valve Spring Retainer
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
well depends .. how far the piston was down and if the valve is still in the valve guide. intake you may have to pull the intake and feed it up from the intake port .. exhaust .. pull the manifold and feed it back up from the exhaust port.. and last .. pull the head .. if the the valve is still in the guide and the piston is not at the top .. you may could turn the engine slowly by hand to the top the piston may push up the valve up . you may be able to pull the valve up then..
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
The direction of the arrow on the valve body refers to the direction of the medium.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. 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.
Q: can't locate freon intake valve for 03 jaguar an was wondering were it is located at
Most manufacturers put the fill nozzle on the hoses, either the high or/and the low side. Also, the low side can be found on the accumulator.
Our valve is widely used in petroleum, chemicals, power, metallurgical, pharmaceutical and other industries.Our campany insists on surviving on high quality, creating with science and benefiting from management.
