CHECK VALVE SWING DUCTILE IRON/ WCB DN40- DN600

Q: My house is public flue, a total of six floor I live five floors, with the side suction hood, hood in the windy outside started as soon as the check valve pops ring from occupancy, have what way?: The hood check valve is in two halves of plastic. It is too light and the wind vibrates. You can add some things, as long as the soot blowing function is OK (try several times). Able to solve problems.

Q: The check valve for the printer doesn't have any air in it, but it doesn't come out. It still doesn't work: Just change the CISS, change after dozens of photos. There is air in the pipe, the printing document is half a page, and then a check valve is installed. After it is finished, there is no air in the pipe, but it can not be played. The nozzle is not out of water any more. The ink in the ink box is full.When the check valve is installed, you can print the test paper color is correct, but the document is a piece of white paper. No more printing later. Say at least one cartridge problem. Where does the check valve open? No, there's a switchChasing the answerNot quite clear, you change the model, the general print cartridge does not leak, the ink box for the gas hole to open, hose without bubbles, you can print normally.

Q: What is the difference between the check valve rcvx and SFCV?: 3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.

Q: Above the flue that valve is called smoke exhaust valve or check valve, I heard there is a five anti exhaust valve: The names are different, and they are acceptable. Five, anti exhaust valve is unique to 10000, the first class of technical effects

Q: Does the check valve damage affect the flow rate?: Ball check valve will not affect the flow, such as the clip type check valve once damaged, it will affect the flow.

Q: Should the flue check valve be made by the civil team or the installation team?: The kitchen flue and check valve are all constructed by civil engineering.

Q: Does the regulator have a check action? If yes, can I use it as a check valve?: The regulating valve is to adjust the pressure, and the check valve is to prevent the backflow of fluid.Clear division of labor, non-interference in each other.Even if some special pressure regulating valve has a non-return function, it can not be used as check valve.It is recommended to install a check valve on the pipe to make sure it is safe.Hope to be of help to you!

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: Is the check valve the same?: Same。 Call a difference; a thing. You come to our store to have a look.

Q: Are check and check valves the same kind of thing?: Yes, that's right. Ha-ha。 My friend needs an anti - stop valve to find me. I have one for sale here.
