Wafer Check Valve

Q: What is the function of the check valve?: The function of the check valve is to prevent the medium from flowing back! Check valves, which are commonly known as check valves! Backflow of medium will cause the reverse of pump impeller, which may lead to the burnout of pump! Pumps used in industry are expensive nowadays! Ha-ha！ The check valve just protects the pump and piping!

Q: What is the difference between check and check valves? Check and check valves?: 2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.

Q: How can the check in the faucet prevent water from flowing backwards?: Not to prevent backflow, is able to quickly shut the water, for triple bathtub, can effectively stop the conversion between the bath and small shower water, there is a spring, when the water pressure will be water, a small amount of Water Leakage was shut up

Q: What is the material of H41W-16's check valve?: According to: JB/T 308-2004 "valve type programming method"H check valve4 flange connection1 lift through straight through valve passageW sealing cover for body material16 nominal pressure PN16When the nominal pressure is less than or equal to PN16, do not mark the material code of the valve body, the valve body material is gray iron

Q: What is the function of the ventilator's 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 block gasFlow in reverse direction. When the soot exhauster starts to work, the air flow with the oil smoke pushes the one-way smoke valve through the air inlet and the flow guiding curved surface, and the soot is discharged into the public smokeWhen the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.

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)?: 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: Tap water tank with vertical and horizontal check valve.: Extrusion includes seat and plate or piston designed to prevent the valve slamming. Additional material added to the seat produces two extrusion zones. Try to squeeze the fluid out of these areas and slow down the valve during rapid closing. But there is a price to pay for that. The limited gap increase region is an ideal site for collecting small solid particles. The squeeze pressure protection for controlled closure, due to the collection of solids, may cause additional problems, unless the gap is sufficiently extruded, the solids can be ejected. A narrow seal may shatter a fragile solid, such as coal. The extrusion zone tends to expand the width of the available valve seat and reduce the ability of the valve to crush solids. This effect must be considered, taking into account all the characteristics of the related solids.

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: Do you still need to check valve fittings for solar water heater installation?: Now do not install check valve, install the hand to valve, at the bottom

Q: How to install fire fighting pipe and flue fire check valve?: 7, the flue is thin-walled components, in handling and installation should be gently handle, not to impact, not in the pipeline to pile other heavy objects and walking.8, the roof flue should be in the roof insulation layer, fire layer before construction.9, the use of gas water heater exhaust system is strictly prohibited.
