Q:How much is the 6 point check valve for the water pipe at home?: Different places, different prices, it is estimated that 20-30 copper. Complete check is impossible, and the effect depends on the actual situation,

Q:Check valve does not automatically check back, how to adjust?: 4 the vertical lift check valve shall be mounted on a vertical pipe.5, the lift type horizontal check valve shall be installed on the horizontal pipe.6. Do not check the weight of the valve in the line. The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system.

Q:The difference between backflow preventer and check valve: Plain and simpleBackflow preventer is double acting, better than check valve

Q:The air pipe is equipped with a check valve: Directly to the outdoor exhaust pipe with a check valve, to prevent windy days, indoor negative pressure, air intrusion.

Q:Are check and check valves the same kind of thing?: The same thing is not the same as it is

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:The difference between slow closed valve and open the valve: The difference is mainly that the opening and closing of the slow closing check valve depend on the external and external forces to perform the slow opening and closing (usually hydraulic cylinder or pneumatic cylinder). The swing check valve is opened and closed by the pressure of the pipe medium to complete the opening and closing (and the pressure of the pipeline).

Q:Can the swing check valve stand upright?: Ordinary lift check valves shall not be erected. Lift check valves with springs can also be mounted.

Q:Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?: If it is water medium butterfly valve, in fact, the same, are used to prevent the media back of the valve, on the models are manufacturers themselves, there is no uniform standard, but only in the use of media on the difference.Butterfly buffer check valve is to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, counter flow valve, and back pressure valveMicro resistance slow closing check valve, also known as check valve, its role is to prevent the medium back flow in the pipeline.

Q:How can the lift vertical check valve be distinguished from the lift horizontal check valve?: 1, vertical lift check valve should be installed on the vertical pipe. 2, lift type horizontal check valve should be installed in the horizontal pipe.Vertical lift check valve, also known as vertical check valve;Lifting horizontal valve check valve, also known as horizontal check valve.Lift check valve: check valve sliding along the vertical centerline of valve body, lift check valve can only be installed on horizontal pipe,Disc can be used in 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 by the media force open, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect.Through lift check valve, the direction of inlet and outlet of medium is perpendicular to the direction of valve seat passage;Vertical lift check valve, the direction of its medium inlet and outlet passage is the same as that of valve seat passage, and its flow resistance is smaller than straight through.
