Q:I have to use a check valve to prevent return water due to pipe installation problems due to regular water supply. But the recent discovery of a running water phenomenon, just on a full tank of water slowly from the pipeline flow away, but not all go, a flow did not flow, time is not the same, but sometimes sometimes does not flow, this is going on, ask professional personage answer: You should be horizontal check valve, with pressure difference, water pressure is not lost; or a check valve inside where the card, must be a certain pressure to baffle back.The problem can't be solved: if you change the pipe, you'll have a vertical check valve

Q:How to install the check valve?: Mounting position of check valve:Installed in the cut-off valve (solenoid valve, pneumatic valve, etc.), to prevent the back of the valve medium, the formation of back pressure or water hammer, affecting the normal use of the front valve.Check valve installed in the pipe bend elbow or vertical direction of the drop is larger, but also to prevent water hammer impact on the pipeline and damage.

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 happens when the check valve is broken?: Check valve is broken, there will be back water, down pressure, serious will produce pump reversal, burning motor

Q:What's the difference between the cut-off, check, check, and stop valves three? Better picture,: Stop check valve: when the handwheel is rotated so that the valve stem rises, the disc does not rise together, but only the valve clack is released.

Q:What type of check valve is the h61y-40 check valve?: I. lift check valves: check valves that slide along the vertical centerline of the valve body. The lift check valves can only be installed on the horizontal pipe. The disc can be used in the high pressure small bore check valve. The valve body of the lift check valve is the same as the cut-off valve (which can be used with the stop valve), so it has a large coefficient of fluid resistance. The structure is similar to the cut-off valve, the valve body and the disc are the same as the cut-off valve. The lower part of the upper valve and the valve cover processing guide sleeve, the valve in the valve lift free guide simple simple light driven, when the medium downstream, the valve thrust open by the media, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect. Straight through lift type check valve medium channel with import and export channel direction perpendicular to the valve seat; vertical lift check valve, the media import and export channel in the direction of the same direction with the valve seat, the flow resistance is smaller than the straight through.

Q:Does the check valve of the flue of the range hood work?: There is also a smoke exhaust smoke fire check valveThe utility model is installed at the rear end of a kitchen fume exhauster or a toilet exhaust fan to a common exhaust pipe inlet with a fireproof grade, and the fan is opened (exhaust gas) when working. In the fan does not work naturally closed (to prevent backflow, waste) or common duct inside temperature reaches a set value can be automatically closed, and within the stipulated period of time to meet the fire performance requirements, the role of smoke from fire retardant valve. This metal valve works on more, the basic effect should be good.

Q:What is the function of the ventilator's check valve?: The utility model relates to a flue check valve, which belongs to an automatic valve, and the main function of the utility model is to prevent the backflow of oil smoke, and only to flow in one direction, and to block gasFlow in reverse direction. When the soot exhauster starts to work, the air flow with the oil smoke pushes the one-way smoke valve through the air inlet and the flow guiding curved surface, and the soot is discharged into the public smokeWhen the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.

Q:How to control the common flue return and smoke return?: In the decoration practice, in order to smoke more smoothly, often install lampblack machine, workers will tear down the developer of the check valve. Even then, there will be no recharge.If you check the check valve is no problem, then only the design of the flue, the smoke does not flow smoothly to the outlet. It is not the problem of lampblack machine.

Q:How do I install the pump outlet check valve?: Order note: 1. Pump outlet check valveProduct name and model number 2. Whether or not to take accessories for our correct selection. Use pressure. Use medium temperature.Two, if the company has been selected by the design unitPump outlet check valve type, please pump outlet check valveThe model is ordered directly from our sales department.Three, when the use of the occasion is very important or the environment is more complex, please try to provide design drawings and detailed parameters, by our valve company experts for your audit checks.
