- 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 can not stop water, how to solve?
- See if there is anything dirty inside! See if the valve is broken!
- Q:What are the differences between different check valves applications?
- Swing check valve to rotate around the shaft, the fluid resistance is generally less than the lift check valve, which applies to the larger diameter of the occasion, the installation location restrictions, usually installed in horizontal pipelines, it applies with large 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 for medium and medium duty applications. Large diameter pipeline using single swing check valve, in order to reduce the water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double valve swing check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a fast check valve. Multi disc swing check valve is suitable for large diameter pipeline
- Q:Where can I find the good check valve?
- If the soft seal check valve, or buy Tianjin Hengyuan valve, good quality, moderate price, have the shelf life.
- Q:What type of check valve should be installed before the suction pump?
- second body cover seal welded forged steel check valve, connected by this form of valve, the valve body and the valve cover are connected by screw, all welded seal, the advantage of no leakage.
- 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:What's the difference between the cut-off check valve and the stop valve?
- Purely from the outward appearance is indistinguishable, but if you do not open the valve body, it can still be differentiated. Turn off the check valve and stop valve (turn the handwheel to the open, the valve stem up), and then shake the two valve, which is relatively large movement, then this is the cut-off check valve.
- Q:How to install the kitchen flue check valve?
- First, we should pay attention to the direction of check valve opening, open the location to smoke pipe opposite;Second, we should pay attention to check valve and common flue or after the installation of household flue sealing point, if the conditions are called thick putty plugging;Third, after the check valve is installed and fixed, the smoke exhaust pipe should be tightly packed with the check valve.Remark: when choosing check valve, choose a brand with better sealing effect, such as submarine.
- 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:What's the size of the check sleeve?
- According to the valve connection mode (thread connection, flange connection), select valve rating, modify the valve name
