Q:Can the check valve be used on the steam pipe?
The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
Q:Method for mounting back check valve of pump
Installation method of pump outlet check valve:1, swing check valve is generally installed in the horizontal pipe: for caliber DN~80mm check valve, can also be installed in theVertical or upward sloping pipe.2, the straight through lift check valve should be installed on the horizontal pipe;3, vertical lift check valve must be installed on the vertical pipe, the medium for bottom-up flow.As the check valve is easy to damage, therefore, should be installed near the pump outlet valve, in the upper part of the check valve with a cut-off valve (general use of ball valve or gate valve), easy to overhaul.

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.4, the installation of flue should each layer as bearing, bearing steel 2 root diameter over 14mm?.5. After the flue is installed, install the check valve hole at each flueFire type flue check valveFirst, stir the cement with a special glue, coat the edges of the check valve, and then install it at the opening of the check valve.6, the construction should be reserved at all levels of the hole, covered with a cover plate, to ensure safety in construction, to prevent construction waste fall into the flue.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.
Q:Check valve authentication information
Consult the manufacturer for more information.Canadian, Registration, Number, CRN certificationMany of the Check-All valves have also been registered in Canada (0C3651.5R1C).
