- Q: How do you draw the butterfly valve in the engineering drawing?
- Butterfly valve there are many kinds of painting, according to the design institute out of the icon, below we together to understand the icon, which has the butterfly drawing.
- Q: Import electric butterfly valve which brand is more reliable?
- Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
- Q: Are fire fighting signal valves and signal butterfly valves the same thing?
- The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.
- Q: The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
- Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
- Q: How to use the fire butterfly valve properly?
- Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements
- 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
- I've had a couple of patients tell me they could hear their metallic valves in the quiet of the night. It isn't something that would bother you all the time. The anticoagulant needed makes a lot of people choose the pig valve, but the latter will wear out and need replacement periodically. Lewis Grizzard, who died from complications of his fourth valve replacement, wrote a book They Tore Out My Heart and Stomped That Sucker Flat, that was half about his aortic valve and half about his love life, the author having had as many ex-wives as heart valves. It may be difficult to find a copy now, but it's a book you'd enjoy reading, and contemplating it (and him) might help you decide.
- 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: How do the butterfly valves d341 and d343 differ in appearance?
- Under normal circumstances, 41 is soft seal body, 43 is hard sealing valve body
- Q: What is the difference between the installation and function of a butterfly valve and butterfly valve?
- Therefore, the fully open position of the valve is determined by the position of the gate. Some gate valve, stem nut is located on the gate, the handwheel rotates to drive the stem to rotate, and make the gate lift, this kind of valve is called rotary bar gate valve, or call dark rod gate valve. The type of gate width, sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate type valve can be divided into single and dual gate gate plate. According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve. Valve installation and maintenance should pay attention to the following: hand wheel, handle and transmission mechanism are not allowed for lifting, and is strictly prohibited. Double gate valve should be installed vertically, that is, the valve stem is in a vertical position, and the handwheel is at the top. The gate valve with bypass valve shall be opened before opening to balance the pressure difference between inlet and outlet and reduce the opening force. The gate valve with drive mechanism is installed according to the instruction of the product instruction. If the valve is constantly switched on, lubricate it at least once a month. The valve has the advantages of small fluid resistance, the sealing surface by the erosion of small and medium Chong brush. Opening and closing is more labor-saving. Medium flow direction is unrestricted, no disturbance, no pressure reduction. The utility model has the advantages of simple shape, short structural length, good manufacturing technique and wide application range. Valve faults between the sealing surface can lead to erosion and abrasion, maintenance more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
- 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)
