Q: The difference between butterfly valve and gate valve
Its varieties and quantities are still expanding, and the development of high temperature, high pressure, large caliber, high sealing, long life, excellent regulation, as well as multi-function development of one valve. Its reliability and other performance indicators have reached a high level. Disadvantages, there is a certain resistance to the medium. Gate valves are more used in steam pipes and large diameter water supply pipelines, because of the general requirements of fluid resistance is small, the use of gate valve. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open. Need a higher installation space, the valve sealing surface has a certain self sealing capacity, its spool by the media pressure closely with the valve seat sealing surface contact, to achieve tight leakage.
Q: I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
The first source, pages 20-22, lists all 9 basic types of EGR valves. Not all the types are vacuum operated, but check out #5 and #6 - they behave very differently from each other without a real live exhaust system connected to them.
Q: Function of signal butterfly valve in fire sprinkler system
The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
Q: I have put a new pressure valve and replaced both thermostat
so that should have fixed it I wonder if you needed to replace the stats
Q: Specifically an engine valve retainer.
This Site Might Help You. RE: What if the function of a valve retainer? Specifically an engine valve retainer.
Q: Types of butterfly valves
There are clip on butterfly valves and flanged butterfly valves,Manual, pneumatic, electric,
Q: What is the national standard for clip butterfly valves?
GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
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: 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?
It is better to set up the valve well for repairing the valve later;If it is extended to reveal the valve well, the waterproof of the well must also be considered. Otherwise, a rainy well will be full.
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)
