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: When will Butterfly Valves be used?: Butterfly valve is the most common and most widely used in the field of the valve, cases of sewage treatment, water supply, iron and steel, building construction and heating fields needs a lot of valves, especially with the hard seal butterfly valve butterfly valve position and a lot of popularity, the field is used more widely.

Q: Ok, so I took my car in for maintenance (Mustang GT convertible 2002) and the mechanic told me the valve gaskets needed to be replaced and when he gave me the estimate, they were two seperate charges for valve gaskets and valve covers, total of about $250.00 not including labor. Is he trying to rip me off cause I'm a girl by the way? Anyways, I didn't get it done cause it needed something else too and I didn't have enough money so I said I would be back in two weeks. So I called the dealership to inquire about the price and I asked the parts guy for a price on valve gaskets and he was like, I don't know what you mean, we have valve cover gaskets but nothing says just valve gaskets? I told him to give me the price anyways, thinking I would ask my brother (who hasn't tried to help me anyways) and it was $60.00 for both (I need two). How can this be if the other guy was charging me $250.00 for different parts? Help!!! Frustrated and confused, I don't know anything about cars :(: Your car has 2 valve covers hence,2 valve cover gaskets. Not valve gaskets. Maybe one of the valve covers needs replacing? If the valve covers or gaskets need replacing your car will be leaking oil from under the hood.

Q: For whatever reason, Mazda has made it next to impossible to change the PCV valve on the 929. I'm going to have to pull off the plenum and the passenger's side valve cover to replace a $2.00 PCV valve. Before I get too involved, I need to know the torque specs for the valve cover. Also, any other tips on this process would be greatly appreciated. Can I reuse the old valve cover gasket if it's still in good shape? Should I use any kind of sealant in addition to the gasket when I put it all back together? Thanks in advance, by looking at this motor, I can tell I'll have my work cut out for me (for a friggin $2.00 PCV valve, it's usually SO simple!). Like I said, any and all help is greatly appreciated.: Mazda 929 Specs

Q: Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?: Sounds okorder /

Q: How does the pneumatic butterfly valve control the angle of opening?: This is really not good, control seems to be pneumatic defects, can only rely on the feeling

Q: How to calculate the size of the manual butterfly valve?: 1. The size of the installation fits only two: the length of the structure and the distance between the flanges.2, butterfly (Manual butterfly) butterfly plate installed in the pipe diameter direction. 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 valve structure is simple, small size, light weight, only by a few parts. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better. 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.

Q: How do hydraulic butterfly valves work?: 3. butterfly valve hydraulic drive device structureThe valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. A section of optical axis is arranged at the end of the driving shaft and is inserted into the end of the manual shaft (matched with the clearance of H11/ H11), and the function is that the manual shaft is concentric with the main drive shaft. In normal operation, the optical axis rotates with the drive shaft, but the manual device does not move. When the hydraulic operation is performed manually or manually from the hydraulic unit, a * * * conversion is required. The utility model is composed of a nut, a hand wheel, a screw rod, a support frame and a shifting device. When the utility model is switched, the hand wheel is rotated and driven by the screw rod to move. A guide rod is arranged on the bracket to make the shift and translation stable.

Q: 19 years ago i had a valve repair and now im due to have heart valve replacement. I heard that the metal valve make noise has anyone who has had the metal valve have this type f problem or any other problem with the metal valve it would be a great help if anyone could answer: Do you want to have kids or have more kids? This is going to be the biggest question you have to answer. The tissue valve will require no treatment after the replacement, other than another replacement in 10-15 years or whenever the valve starts to fail. The mechanical valve will most likely last the rest of your life, but will require the use of anticoagulants that would make any future pregnancy extremely risky. As to the sound many patients complain about hearing the valve clicking in times when it is very silent (dead of night etc.) Most find that keeping a Radio or tv on at a low level solves the problem, Id say in my experience about 50% of patients complain about hearing the clicking. The other issue is that using tissue valves, it is a slightly riskier operation every time you re-open someones chest, due to scar tissue formation. So instead of say 1-3% risk it might be 5% if the person is young and healthy. This is important since the tissue valve will only last 10 maybe 15 years. The atrial thrombus complicates matters, however which valve are they replacing? It might be possible to remove the thrombus at the same time as doing the valve. If not, mo matter what you will be taking warfarin, so the vavle choice really will not matter that much.

Q: What's the difference between an electric two position control valve and an electric butterfly valve?: Double switch electric butterfly valve, electric butterfly valve is usually said, namely the electric butterfly valve in the electronic case can achieve fully open or fully closed precise place to stop, not directly with the pipeline system flow feedback device for regulating the flow of accurate interaction.
