Q:What do D71, D371 and D341 represent in butterfly valves?
D71 is a handle to clip butterfly valveD371 is a turbine to clip butterfly valveD341 is a manually operated double flanged butterfly valve
Q:Timing belt reason for bent valve?
Yes, unless you've left out a critical detail (such as getting water into a cylinder), the timing belt is the most likely explanation for your bent valve. It doesn't neccessarily mean the person who 'did' your timing belt buggered it up, it may have just slipped. The short-ish period between getting work done and the valve getting bent is a little suspicious, but slips happen, especially with belts (as opposed to chains and dual row chains). This puts you in a difficult situation. You may also want to inspect your valvetrain, piston face, and the bore of that cylinder for damage.
Q:Which is better, the round two lobe butterfly valve?
Can be directly installed in the ventilation pipe, connected with the wind pipe, used to control the speed, adjust the indoor air, the double structure diagram can reduce the space length of the blade is unfolded, and also has the characteristics of small airflow resistance, convenient adjustment etc.
Q:What's the difference between an electric two position control valve and an electric butterfly valve?
With manual control device, once the power failure occurs, you can temporarily manually operated, and will not affect the use.The biggest difference is that the electric double bit butterfly valve can not fine adjustment; and the electric butterfly valve can play a regulating role.
Q:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
Louzhu asked extremely, since it is hard seal, it is bound to guarantee long-term work after zero leakage, or should be configured double eccentric soft sealing valve is more reasonable.
Q:What are the uses and classifications of manually operated clip butterfly valves?
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. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.
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:What kind of butterfly valve is sd342x?
Sd342x: two-way double eccentric soft sealing butterfly valveS: two way pressureD: butterfly valve3: turbine operation4: flange connection2: double eccentricX: rubber sealProbably the shape is not so good in appearance,Double eccentric mostly elastic sealThree eccentric is multi-layer sealHope to be of help to youOpened valve Co., Ltd. on the production of butterfly valve
Q:What's the difference between electric butterfly valve and electric two way valve?
Below we will be specific to understand the electric two way valve and electric butterfly valve of the difference between.Distinguish one: product performance is different, the electric two way valve is for the central air-conditioning fan coil supporting products; and electric butterfly valve and electric control valve is the same species;Difference two: the product function is different, the electric two way valve is automatic adjustment; and the electric butterfly valve is a variety of adjustment methods.Difference three: product classification is different, the electric two way valve body activities are more piston style structure; and butterfly valve structure is diversified, such as sealed form can be divided into soft sealing and hard sealing type of two.
Q:Is a valve gasket the same as a valve cover gasket?
here okorder.com/... usually you can tell when a car needs the gasket to be replaced because it will leak oil where the gasket is at the bottom of the cover i think hes ripping you off because cars usually dont need to have the valve cover replaced, just the gaskets so take it to another mechanic and get another estimate
