Q:What about boiler non-return valve without return?
Reliably disconnect the front and rear valves of the check valve and open the check valve spool. 1, lift check valve, remove dirt and impurities out of the valve, and the necessary lifting shaft between the sand, and then check the sealing surface (line), install the recovery; 2, open the valve, visible to the rotary valve plate, sometimes is the axis of rotation is not flexible, it will add oil activities for many times, then look at the rotary valve in the fully open, whether the opening angle is too large, can not rely on medium reflux and gravity recovery closed, if so, then the opening plus limit (which can be in the spool in the valve plate drilling and tapping screw, in a small Luo Si), do not let the valve plate open to the vertical state, which can be opened to an angle of 80 degrees. You can have a try. Good luck. Happy new year.
Q:Are the common check valves stand upright or horizontally installed?
1 straight through lift check valve should be installed in horizontal pipe, when the media to stop the flow, the valve by the weight of landing on the seat to prevent the media back; because the vertical lift check valve medium inlet and outlet channel direction and the direction of the valve seat, so it must be installed in a vertical pipe.
Q:Check valve symbols?
The valve that prevents the backflow of the medium is called a check valve. 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.
Q:Does FOTILE hood have check valve?
Therefore, it is necessary to install a check valve at the flue port.
Q:Ask questions about the installation of check valves after water meters
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:Assembling process of clip type check valve
The light valve solves this problem: this type of valve acts only to allow the medium to flow in one direction, and to prevent the flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.
Q:Use of fire pump adapter even before you install a check valve
Multifunctional pump combination device usually comes with safety valves and check valves, usually in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.
Q:Does the tap water return to the water?
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.
Q:What's the fire check valve?
The valve of the product is opened, and the direction of opening and opening of the side open type fireproof check valve is consistent with the exhaust direction in the exhaust pipe of the smoke exhauster, and the exhaust is smooth.
Q:How many kinds of check valves should be used?
Ball check valve because the sealing part is covered with rubber ball, therefore, good sealing performance, reliable operation, anti water hammer performance; the seals can be a single ball, they can make more balls, so you can make large caliber. But its seal is wrapped in rubber hollow sphere, does not apply to high pressure pipeline, only applies to the middle and low pressure pipeline.Because the shell material of spherical check valve can be made of stainless steel, sealed hollow sphere parts can be coated PTFE plastics, can also be applied in the pipeline so general corrosive medium.The check valve in the working temperature between -101~150 DEG C, the nominal pressure is less than 4.0Mpa, nominal in the range of 200~1200mm
