Q:Timing belt reason for bent valve?
A TDI has no valve to piston clearance as a results of the indisputable fact that's a diesel and has a extreme compression ratio. i'm a mechanic myself and hate to slam different techs yet it truly is clearly a screw-up on his section. There are some issues that would have exceeded off even if the shop he works at is to blame for the damages. If the tensioner did bend (which I surprisingly doubt exceeded off) then he has recourse by the business business enterprise that man made the tensioner yet to be quite truthful, it truly is only no longer real. similar is going for the snatch problem. that only isn't plausible. good success.
Q:how does variable valve work?
The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.
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:What's the difference between cut-off valve, gate valve and butterfly valve? What's the difference in the working principle?
Stop valve is closed parts (valve) moving along the centerline of the valve seat, the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional to the amount of adjustment is also very suitable for convection.Check valve: also known as counter flow valve, check valve, back pressure valve or one-way valve, such valves are dependent on the flow of the pipeline itself flow force and automatically open and close, belonging to an automatic valveButterfly valve: it is a kind of valve which uses disc type opening and closing parts to turn back and forth about 90 degrees to open, close and adjust the passage of fluidGate valve is closed parts (RAM) along the vertical axis of the mobile channel valve in the pipeline, used primarily as a medium cut that open and close, generally do not have to do with traffic regulation, it can be used for low temperature and low pressure can also apply to high temperature and high pressure, and according to the different valve material is different in various media. The valve, the valve is the most widely used.
Q:How can the flange butterfly valve be installed on the pipe?
Direction.Butterfly valve in theory can be installed in any direction, it is recommended that the horizontal installation of the valve shaft installation, so that both ends of the bearings will not be at the bottom (below), so as to avoid sediment in the media into the bearing.Inlet pipe configuration.There are water inlet side valve elbow, tee pipe fluid caused by bending and uneven distribution of the inflow valve, the drift will occur in the pipe, so it must be generated by the uniform drift disposed on both sides of the disc, so as to avoid uneven force on both sides of the disc, and may produce additional torque.
Q:What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
1, the drive mode is different (handle or turbine), mainly based on the size of the valve and the opening and closing torque to decide.2. The butterfly plate of the worm valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees ~90 degrees between, when rotates to 90 degrees, the valve opens the card completely.3, clip type butterfly valve is to use double headed bolts to connect the valve between the two pipe flanges, flange butterfly valve is a valve with a flange, bolt with the valve flange at both ends connected to the pipe flange.
Q:Butterfly valve in use when should pay attention to what problems?
In the process of using the butterfly valve, you should timely notice valve state, without excessive loosening, no abnormal leakage, or abnormal high temperature and so on, if there is abnormal, should immediately close the valve, to identify the reasons for the problem, treatment after use, it is also very important.
Q:Butterfly valve, two-way pressure and one-way pressure what is the difference?
The positive pressure and the reverse pressure, the pressure when the medium returns
Q:How many kinds of butterfly valves are there?
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.[structure]The utility model is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a butterfly plate.
