CHECK VALVE SWING DUCTILE IRON/ WCB DN40- DN600

Q: Check valve note BC/PISTON: SPR-L what does that mean?: BC==Bolted Cover/ bolted bonnetPISTON== lifting typeSPR-L==Spring-loaded/ is loaded with springsTogether, it is: a spring-loaded check valve. Bolted bonnet (this is common)

Q: Is it necessary to install a check valve in front of the water meter? Does the water company have a definite requirement?: UnnecessaryWater meter before the loss of running water, their own things, do not need customers to bearAfter the water meter is equipped with a small gate valve or a ball valve, it is convenient to repair and replace

Q: What are the ten major brands of copper check valves?: I knew that:1, Amico2, Jie Kelong3 crown4, good day5, KITZ

Q: How can the check valve be distinguished from the cut-off valve?: Stop valve has a handwheel, the general check valve by gravity or spring action, there is no operating mechanism, but the large check valve is there.

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: How can the lift vertical check valve be distinguished from the lift horizontal check valve?: Vertical lift check valves and lift horizontal check valves are different in structure, type, appearance, including installation.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.

Q: What are the differences between the vertical check valve and the horizontal check valve in function and principle?.: The vertical check valve and horizontal check valve are functionally and functionally indistinguishable.The difference between vertical check valve and horizontal check valve:Horizontal check valves, mounted in horizontal pipes, have the same shape as the globe valves; vertical check valves are attached to vertical pipes.Check valve is open and close parts, depending on the flow of medium and power to open or close, to prevent media backflow valve called check valve. The check valve belongs to the automatic valve, mainly used for one-way flow of medium pipe sleep, allowing only medium to flow in one direction, in order to prevent accidents.The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three.

Q: Installation position of household water meter check valve: Generally installed after the water meter.The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter.A check valve is installed after the water meter, so that the situation can be avoided.

Q: How to install the kitchen flue check valve?: First, we should pay attention to the direction of check valve opening, open the location to smoke pipe opposite;Second, we should pay attention to check valve and common flue or after the installation of household flue sealing point, if the conditions are called thick putty plugging;Third, after the check valve is installed and fixed, the smoke exhaust pipe should be tightly packed with the check valve.Remark: when choosing check valve, choose a brand with better sealing effect, such as submarine.

Q: What is the difference between the check valve and the check valve?: The same thing is the flue check valve. We need to contact the manufacturer
