Check Valve (Check Valve) : according to the structure, can be divided into the lift Check Valve, swing Check Valve and butterfly Valve.Lift check valve can be divided into vertical and straight-through type two kinds.Swing check valves can be divided into single type, more than double disc type and disc type 3 kinds.Butterfly check valve as butterfly double valve, butterfly single, the above several kinds of check valve in the connection form can be divided into the thread connection, flange connection, welding and clamp connection of four.

Q:Check valves - check valves - what's the difference between one-way valves?: Check valve. Check valve is the same, but the name is not the same. According to the customary name of the country. In fact, the same valve.

Q:How do I use the triangle and check valves?: The triangle valve is installed before the sanitary ware, the faucet and the appliance, so that it can be repaired after the damage of the faucet and the appliance.The check valve is equipped with a water meter and the water pump is prevented from flowing backwards in front of various water tanks and water pumps.

Q:Detailed distinction between backflow preventer and check valve: The backflow preventer consists of two separated check valves and a drain valve. Due to the local head loss of the check valve, the pressure in the middle cavity is always lower than the pressure at the inlet. This pressure difference causes the drain valve to be closed and the pipe is in normal water supply. In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.Check valves are plain check valves, only one side seal. Backflow preventer is more expensive than ordinary check valve. Double protection and heavy protection!

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: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:Is the check valve the same?: The same thing, the different name, the appraisal finishedPrices vary greatly, probably due to specifications, material, performance and other differencesIf you need to know more, you can call me, see the user name is my Unicom number

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:Why can't the check valve on the air pipe be used when the wind speed is less than 8 meters?: First of all, you must understand the working principle of the check valve, indeed, as you said, you can adjust the position of the hammer by adjusting the position of the drop hammer.If you are in their own design and production, consider the thickness of the blade, drop hammer size, weight, and other parameters considered.Hope to be of help to you!

Q:What is the difference between the check valve and the check valve?: 1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve, the pressure disappears, the spring force the valve, sealing liquid backflow. Often used in the smaller diameter check valve.2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.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:Can the check valves fit two in one tube? One up, the other down: A water pipe is used for launching, and the two check valves that you install are reverse, and the water is blocked by one of the check valves on either side
