Usage/Applications Of Swing Check Valve

-Various modes of the pipeline, prevent the medium backflow

- Products Design Features: Flanged & Butt-welding ends swing check valves are used in pipes under pressures between PN 1.6-16.0MPa,Class 150-900Lb,working temperatures between -29-570 °C, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power generation to prevent the backward flux of the media.

- Operation: Handle operation, electric.

Swing Check Valve

Q: What is the function of the check valve?: 1. Check valve function: prevent backflow of medium, prevent pump and drive motor reverse, and discharge of container medium.2, check valve refers 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 valve. The check valve belongs to an automatic valve.3, check valve according to the structure of the division, can be divided into lift check valve, swing check valve and butterfly check valve three:Lift check valve is divided into two types of vertical and horizontal.Swing check valve is divided into single, double valve and multi flap type of three.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.4, check valve (Check, Valve) installation should pay attention to the following mattersA do not allow the check valve to bear weight in the line, and the large check valve shall be independently supported so as not to be affected by the pressure generated by the piping system.B, when installing, pay attention to the direction of the flow of medium should be in accordance with the direction of the body marked arrow.C and vertical vertical check valves shall be installed on the vertical pipe.D and lift type horizontal check valves shall be installed on horizontal pipes.

Q: What is the air pipe check valve?: The air pipe check valve is installed in the ventilation or air conditioning duct. When the fan is running, the valve is opened and the air flow is passed smoothly. When the fan stops, the valve is closed to prevent the air from reversing.

Q: Why is the water ring vacuum pump equipped with check valves?: The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline

Q: Which type of check valve should be selected for vertical pipes?: The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited

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: The check valve on the air pipe is installed in front of the fan and is there any difference in the back (direction is correct)?: Yes。Installed in front of the wind blowing, the top open check valveIt is difficult to install the check valve, which is installed on the rear by the force of air suction.

Q: Swing check valve can prevent any sewer defection: Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents. This kind of valve should be installed horizontally in the pipeline.

Q: How to install fire fighting pipe and flue fire check valve?: 1, vertical transport, the flue should take protective measures, and must be two lifting.2. Locate the center line of the flue position. In the reserved hole, draw down four vertical central lines from the roof, and draw 2 orthogonal central lines on the floor plane.3, the flue to the scene, the first flue hanging to the roof, surrounded by the center line of pop in the flue, and the flue of the reserved hole slowly down the electric hoist, from top to bottom layer installed flue in place, the center line correction. The center line of the flue and the center line of the reserved hole should be less than 1cm, the deviation of the centerline of the upper and lower flue is not greater than 1cm, and each flue must be guaranteed vertically and vertically.

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: I use water pump pumping 78 meters deep underground water, the pipe is 2.5 inches large, with ordinary check valve, water is always sucked back, I would like to ask what method or what kind of check valve to be selected (check valve to be installed on the side of the pump): 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.
