Product Feature:

1, the disc lift check valve disc, seat around tunnel axis rotation, due to the channel into a streamline in the valve, flow resistance is smaller than l butterfly check valve, suitable for low velocity and flow not often change the large diameter of occasions, but should not be used for oscillating flow, its sealing performance than lift.Butterfly check valve points single type, double disc type and for the most part three, the three forms mainly by the valve diameter, the purpose is to prevent the backflow medium flow or stop, decrease hydraulic shock.

2, lift check valve: disc revolve around pin in the seat of the check valve.Disc check valve has simple structure, can only be installed in horizontal pipe runs, sealing is good.
3, lift check valve: disc sliding along the center line of the body of the valve.Pipeline check valve is a new kind of valve, its small size, light in weight and good processing technology, is one of the check valve development direction.But the fluid drag coefficient is slightly superior to swing check valves.

high quality ductile iron cast iron flanged swing check valve

Q: Check valve H41T-16. What are the numbers and letters in it?: H stands for check valves, 4 for flanges, 1 for lift, T for seal, and 16 for pressure

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: Check valve symbols?: The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve:1. lift check valve is divided into two types of vertical and horizontal.2. swing check valve is divided into single, double flap and multi flap type of three.3. butterfly check valve is straight through type.The above types of check valves can be classified into thread connection, flange connection, welding connection and clamp connection in connection forms of four kinds.

Q: What does the check valve "h61h-25 H" mean?: From the model analysis, for the cast steel welding lift check valve, it depends on your valve is not it

Q: The difference between the plunger type check valve and the lift check valve: Lift check valve is 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).Hope to be of some help to you!

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 to prevent the backflow valve of medium: Check valve operating principleCheck valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).

Q: What is the working principle of the flue 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 prevent the airflow from flowing in opposite directions.Simon common flue check valve is the use of aerodynamics and mechanical principles of lever machinery, the use of South Korea's imports of high-quality ABS LG engineering materials for the material.

Q: What type of check valve should be installed before the suction pump?: second body cover seal welded forged steel check valve, connected by this form of valve, the valve body and the valve cover are connected by screw, all welded seal, the advantage of no leakage.

Q: Is it better to have explicit rules in the relevant specifications? Thank you, ah, ah, urgent.: 8.5.5 vertical exhaust lines for kitchens, bathrooms, toilets, etc., should be taken to prevent backflow or to set fire dampers on the branch pipe.In addition, there are similar provisions in the code for fire protection in architectural design, which are not stated.
