The main role is to prevent media backflow and prevent the pump, as well as to prevent the drive motor reversal and container media discharge check valve, in many areas have been widely used and have a higher visibility. However, even if the operation of a stable check valve is also inevitable in the use of some problems, then when we meet these problems how to solve it? Try some of the methods described below.

Check the common problems in the check valve


 

First, the face of the valve flap broken with the media, to strengthen the daily maintenance and cleaning

The most common failure of the check valve is the disc flap and the media backflow. The reason why the disc is broken mainly before the check valve pressure is close to the balance and mutual "see the" state, after the flap and the seat between the long-term flapping will make some of the brittle material made of the valve broken. When you buy products in advance should try to buy with the strength of the check valve. The reason for the phenomenon of media backflow is mainly due to the destruction of the sealing surface and the inclusion of media, so the use of the time must pay attention to the daily maintenance, protection of sealing surface and remove impurities.

Second, the face of the valve plate is not working, check the relevant parts and in advance to prevent

Even if the high quality and durable check valve, if improper installation or maintenance awareness is low, it is easy to encounter the situation of the valve plate is not working. The first thing to do is check the flap shaft and the guide sleeve on the drain hole is not blocked, or check the valve plate installation. And then check the flap shaft and guide sleeve between the gap is too small to cause serious disc valve shaft wear. After troubleshooting, to clean the equipment in a timely manner to keep clean, and regular inspection and replacement.

Third, the face of rocker mechanism damage, check the parts to be replaced

There is a problem often occurs is the check valve of the rocker mechanism damage, on the one hand is the suspension of the work so that the valve before the valve pressure close to or fluctuation, on the one hand because the production parts failed to make the rocker assembly is not correct The In order to effectively avoid such a situation need to maintain the smooth operation pressure, and the use of regular maintenance.

Above is the check valve in the use of the most common problems in the process, although these problems are not very serious, but if you ignore these seemingly small problems, and not take the appropriate measures will cause more serious s consequence. Not only shorten the life of the product, but also affect the role of the product play, and affect the use of the effect.
