Q: The difference between butterfly valve and gate valve
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: Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Hard seal butterfly valve in any case, the reverse loading will cause tight seal.
Q: Do you use the straight stem butterfly valve in the fire fighting engineering?
Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
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: What are the functions and uses of butterfly valves?
Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for 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.
Q: How can the flange butterfly valve be installed on the pipe?
Outlet pipe configuration.If in the pipeline, the valve in order to do not bear the direction of the force and bending moment, it is best to set the valve at the exit side of the expansion joint. Valve opening and closing valve water pressure should not be borne by the foot, but through the valve flange, by the pipeline to bear as well.Butterfly valve structure is generally shorter length, and its butterfly plate will be extended to adjacent pipes or other parts, so be careful not to collide with other parts and interference. And to prevent the error matching pipe diameter greater than C and collide with the butterfly plate.Butterfly valve as a regulator, just adjust the flow and pressure. The valve is regulated by loss of pressure.
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.
Q: I need a valve cover gasket replacement because mine is leaking a tremendous amount of oil. The mechanic says it will cost about $269.00 plus tax. I wanted to make sure this figure was the average since I do not know a lot about cars. My car is a Mitsubishi Diamante 2001.
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: I did a compression check on my 350 chevy. I have low compression of 175psi on one cylinder.The other seven cylinders range from 195psi to 205psi Could the valves be too tight on the cylinder with 175 psi compression?
Chev engines have hydraulic lifters, keeping the valves adjusted correctly at all times. 20 lbs isn't much to worry about anyway, but if you want dump a little oil (about a tablespoons worth) into that cylinder and recheck it. If the compression jumps up, then your rings are getting weak. If not, you may have a leaky valve.
Q: What's the meaning of butterfly valve d371po?
According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
