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:The self-priming pump with check valve (check valve, water valve)?
Water inlet generally has a check valve, if not, then only in the suction port on the installation of the check valve. Of course, you can also install a one-way valve on the pipe near the suction port.
Q:To prevent water meter rotation, where should the check valve be installed?
Do not pack more than 35 of the weak currentChasing the answerShould be installed at the outlet of the water meter (that is, water to the other side of the room)
Q:What are the differences between the vertical check valve and the horizontal check valve in function and principle?.
The vertical check valve and horizontal check valve are functionally and functionally indistinguishable.The difference between vertical check valve and horizontal check valve:Horizontal check valves, mounted in horizontal pipes, have the same shape as the globe valves; vertical check valves are attached to vertical pipes.Check valve is open and close parts, depending on the flow of medium and power to open or close, to prevent media backflow valve called check valve. The check valve belongs to the automatic valve, mainly used for one-way flow of medium pipe sleep, allowing only medium to flow in one direction, in order to prevent accidents.The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three.
Q:What is the reason that the check valve does not stop water?
1, the valve at both ends of the road must be blocked, there is dry ventilated room. Such as long-term storage, should always check rust corrosion.2, the valve should be cleaned before installation and eliminate the defects during transportation.3, the installation must be carefully checked on the valve signs and nameplates are in line with the use of requirements.
Q:Which side of the gate is the fire check valve in the pump room?
The check valve is installed between the shock absorbing flexible joint and the water outlet control valve at one side of the water outlet pipe of the water pump
Q:The role of the clip lift check valve
It only allows the medium to flow in one direction and 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. Check valves are generally applicable to clean media and are not suitable for media containing solids and viscosity.
Q:Why can't parallel check valve be installed firmly?Anonymous browsing | 51 times
The vertical installation is easy to cause the valve core of the check valve to clamp off or fall off, and lose the function of checking back. The direction of the check valve is restricted seriously from any direction of the medium
Q:Installation position of household water meter check valve
Domestic water meter without the need to install check valve.
Q:How many kinds of structure are there in the check valve?
2. The swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally applicable to medium calibre applications. Large diameter pipeline using single swing check valve, in order to reduce water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a kind of fast developing check valve. Multi valve check valve is suitable for large caliber pipeline;
