3. Feature:
The product consists of body, disc, ring, drive gear and other major parts. Its structure using three-dimensional eccentric principle design, elastic sealing and multi-layer seal compatible with the new technology of processing of hard and soft, make the butterfly valve in operation work, reduce the torque force, to achieve energy saving, energy saving function. To ensure that the overall corrosion resistance. High temperature resistance. And the reliability of the bonding resistance loss.
- Q: Why use special flanges for butterfly valves?
- Because to use special flange butterfly valve butterfly flange diameter is just the butterfly inside diameter of DN coincides with a slot in the back, and this is the connection of the steel pipe is inserted into the slot, so as to ensure the sealing effect, but with a flange piece of ordinary cannot guarantee the effective sealing effect.Butterfly valve plate installed in the direction of the diameter of the pipe. Butterfly valve structure is simple, small size, light weight. Consists of only a few components. 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.If the butterfly valve is used as a flow control, the main thing is to correctly select the size and type of valve. Butterfly valve structure and principle, especially suitable for making large-diameter valves. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve. The clip type butterfly valve is a double headed bolt connecting the valve between the two pipe flanges. The flange type butterfly valve is provided with a flange on the valve, and a bolt is used to connect the flanges at the ends of the valve to the pipe flange.
- Q: How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?
- The difference between one way butterfly valve and two way butterfly valve:One way hard sealing butterfly valve:The butterfly's body usually has an arrow to indicate the direction of media flow, the butterfly valve plate in front of the closed, must face the flow of media, so we should pay attention to the medium flow direction when installing a one-way valve.
- Q: I have put a new pressure valve and replaced both thermostat
- If you have replaced the TP valve, more than likely there is a heating element shorted to the tank. This will cause continuous heating and high temp/high pressure...good luck.
- Q: My bike has now 6200 miles on the odometer. The manual says that a valve adjustment should be performed every 6000 miles. But the bike runs fine. Can I just have the valve checked or should I have them adjusted even though the bike is fine? What will happen if I just keep riding it?
- In reality, lots of bikes go their entire lives without a valve adjustment. In my opinion that is a great way to ruin a bike though. They have a maintence schedule for a reason. If a valve isn't seating, it can hurt performance and the valve will not be able to transfer heat to the head. That can burn a valve and cause detonation. You have to check valves to adjust them, and the labor for just checking will be nearly the same or identical to doing the adjustments. I do all my own wrenching, so money isn't really an issue, but if I were you, I would just bite the bullet and take it in.
- Q: Butterfly valve network and ordinary butterfly what is the difference?
- Butterfly valve used in the network structure, closed with the more closed, the more tight function, reliable sealing performance, after opening and closing, make sure that the cover is completely out of touch, to ensure that the sealing surface is not damaged. The sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by the spatial units, can be installed in any direction.
- Q: That industry uses most of the butterfly valve, and only use the butterfly valve, a large number of use of butterfly valve, seek expert advice!
- I know there are automatic fire fighting systems and the oil industry.
- Q: Butterfly valve in the use of the difference? Caliber?
- According to the function and use of the valve and butterfly valve, gate valve, small flow resistance, good sealing performance, the valve plate and the flow direction of the medium is the vertical angle, if the valve is not in place in the valve plate switch, wash medium on the valve plate of the valve plate is easy to fibrillation, according to valve seal damage.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: What's the difference between an electric two position control valve and an electric butterfly valve?
- The electric butterfly valve belongs to a kind of electric valve and electric control valve. The main connection modes of electric butterfly valve are flange type and clip type. The main forms of electric butterfly valve are rubber seal and metal seal. The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as the shut-off valve, control valve and check valve of the piping system.
- Q: Which is more expensive, gate valve or butterfly valve?
- Gate valve.Under normal circumstances, if you need to adjust the good point, to use the gate valve, and if better, you can choose the cut-off valve.But the price is also butterfly valve, gate valve, globe valve increasing.
- Q: Buried extension butterfly valve is buried or need to repair the valve well, can build the valve well, the extension rod butterfly valve installed in the valve well, the extension rod to avoid covers, the top of the valve well out, so that the hand wheel in the ground operation.Atlas S143 is less than the inner diameter of DN150 valve wells only 1200mm, DN200-DN250D diameter of only 1400mm, 700mm valve covers, valve rod and a handwheel to lengthen through the valve cover, valve wells is built to cover the embedded pipe or tube? Is there a standard atlas?
- Hand wheel operation in the ground, the original operation on the ground, our company's extension rod is in accordance with the length specified by the manufacturer.
