Q:Check valve H15B-16 DN25 is that product?
Screw swing multi valve check - nominal pressure 1.6Mpa, product caliber 25mmOur company has production!
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:How can the lift vertical check valve be distinguished from the lift horizontal check valve?
1, vertical lift check valve should be installed on the vertical pipe. 2, lift type horizontal check valve should be installed in the horizontal pipe.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:Why is the intelligent water meter equipped with a check valve, still can not prevent the water meter idling?
2.3 installation methods and installation quality2.3.1 since the water meter is now out of the door, most of the units are all concentrated in one box and installed on the first floor. Taking into account the freezing cold winter and the meter, with 6 or 12 meter with a diameter of 40mm- 50mm diameter pipe, tables and small spacing and straight sections set aside less water, this will also affect the normal water metering, causing water rotation.2.3.2 installation quality, pipeline projects are basically buried in the ground or in the wall, is a hidden project. National construction standard pipe provides various pipe pipeline construction installation requirements, construction process, acceptance criteria and matters needing attention, but in the construction site, some managers do not according to the requirements of the code construction, more or less there are some quality problems caused by pipeline.
Q:What's the difference between the check valve and the stop valve?
The check valve is not the same as the cut-off valve. The difference between them is mainly that the structure is very different.Check valve is a one-way valve, automatically prevent reverse flow of fluid, no knob, can not be artificial blocking forward flow.The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.
Q:Installation position of air pipe check valve
Texture of material1. cast iron check valve2. brass check valve3. stainless steel check valve4. carbon steel check valve5. forged steel check valveCheck 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).The function of this type of valve is to allow the medium to flow in one direction and to prevent 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:Is the check valve behind or behind the gate valve? Why?
Thank youPlease install it in frontWhat about the front?
Q:What does the H/F/P stand for in the check valve H41H/H41F/H41P?
Respectively, the valve seat sealing surface is made of alloy / fluorine plastic / stainless steel.
Q:Is the tank stop valve a non-return valve or a check valve?
Check valve is a one-way valve, automatically prevent reverse flow of fluid, no knob, can not be artificial blocking forward flow.
Q:Does FOTILE hood have check valve?
Therefore, it is necessary to install a check valve at the flue port.
