Q: Can the flue check valve and kitchen check valve protect against odor?
Not really. It depends on what valve it is. If it is a variable pressure air valve, of course, if it is an ordinary other valves, generally only temporary role. Five residential home kitchen platoon smoke system is the application of this variable pressure air valve.
Q: Can the check valve be used on the steam pipe?
The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
Q: How much pressure is the check valve h47x-10q?
Check valve h47x-10q is 1.0MPa pressureAccording to the provisions of the JB/T 308-2004 valve type programming method:H== check valve4== connection: flange7== structure: butterfly typeX== sealing surface material: Rubber10== pressure rating: 1.0MPaQ== body material: ductile iron
Q: What is the difference between check and check valves? Check and check valves?
2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.
Q: God, can you explain to me in detail why?
Pump outlet, check valve, gate valve.Gate valve plays a regulatory role, is the main pipe. Such a sequence can ensure that the water flow during power failure does not cause damage to the gate valve.
Q: What's the difference between check valves and non-return valves?
Other check valves (check valves), such as blowdown check valves,Civil air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.
Q: What does "H" for H42W check valves mean?
through type ---1B. vertical ---2SwingA. single ---4B. multi flap ---5C. double flap ---6ButterflyA. double valve ---7B. single ---8Shuttle ----9H: Valve code, is the check valve code, 4: connection mode is flange connection; 2: valve form is vertical lift; W: sealed form, on behalf of the body of the sealing surface
Q: How much is the check valve for the concrete pump?
31 concrete pump price ranging from 15W to 60W, different configurations have different prices, which one do you want?
Q: Is it better to have explicit rules in the relevant specifications? Thank you, ah, ah, urgent.
8.5.5 vertical exhaust lines for kitchens, bathrooms, toilets, etc., should be taken to prevent backflow or to set fire dampers on the branch pipe.In addition, there are similar provisions in the code for fire protection in architectural design, which are not stated.
Q: I use water pump pumping 78 meters deep underground water, the pipe is 2.5 inches large, with ordinary check valve, water is always sucked back, I would like to ask what method or what kind of check valve to be selected (check valve to be installed on the side of the pump)
1, do not use ordinary ball check valve, rubber check valve, quick response, but it is not very durable2, vacuum tank3, I think the most benevolent is, get an auxiliary start pump, small kind of, the head is not too high, connect the municipal pipe network, open the main pump before the auxiliary pump irrigation. But the premise is that your main pump is a centrifugal pump
