Q:What are the specifications of the DN200 check valve?
The silent check valve is suitable for water supply and drainage, fire fighting and heating and ventilation systems. It can be installed at the outlet of water pump to prevent the backflow of medium and the damage of water hammer to the pump.Liquid control check valve is suitable for the pump outlet pipe of medium water, as closed circuit and check valve. It is used to avoid and reduce the medium prosperity, reverse flow and excessive water hammer in pipeline system, so as to protect pipeline system.The swing of the swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. Swing check valve according to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally suitable for medium calibre applications.The structure of the lift check valve is similar to that of the globe valve. The valve is used to move up and down along the channel. The action is reliable, but the resistance of the fluid is large. It is suitable for light and small caliber occasions. Lift check valves can be straight through and vertical two. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe.The micro resistance slow closing check valve is used for the water supply and drainage pipeline and is installed at the outlet of the water pump to prevent the medium reverse flow and eliminate the destructive water hammer, and can effectively reduce the water hammer pressure of the valve closing, and can ensure the safe operation of the pipe network.
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:What is the difference between the check valve h64h-250 and the h61y-250?
According to JB/T308-2004 "valve type programming method"One is the swing check valve (4), and the sealing surface is Cr13 (H)One is the lift check valve (1), and the sealing surface is made of Y
Q:Ball shaped sewage check valve pictures and working principle of the structure.
Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
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:Are rubber check valves and swing check valves the same type of valves?
Swing check valve is a check valve, the structure of the valve for the rotation of the axis of the general term, rubber valve check valve is people's usual name for H44X, only a swing check valve
Q:What is the function of the check valve in the pipeline?
Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline.Pump water off the bottom valve check valve also belongs to class. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valve is automatic valve, check valve is mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.The installation of the check valve shall pay attention to the following1. Do not allow the check valve to bear weight 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. 2, installation, pay attention to medium flow direction should be in accordance with the body of the ticket arrow direction.3, vertical lift check valve should be installed on the vertical pipe.4, lift type horizontal check valve should be installed in the horizontal pipe.
Q:Automatic water tower water reflux, plus a check valve not supposed
Check the direction of the installation is correct, check valve quality is good, you can install two check valve. Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
Q:What's the difference between check valves and non-return valves?
Check valves are check valvesThe check valve is only a one-way start and stop valve to prevent the flow of fluid medium on all kinds of pipelines or equipment.Check valves are widely used and come in many different types,The following is a common check valve for water supply and heating:1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve,After the pressure disappears, the spring force presses down the disc and seals the liquid back.Often used in the smaller diameter check valve.
Q:Check valve selection
The ideal way is to set up a vacuum tank so that it doesn't return all the time without irrigation each time. Check valve because of different quality, more or less water leakage, stop time will be long after the leak.
