There will be defects in any casting. The existence of these defects will bring great hidden danger to the internal quality of the casting. The welding repair to eliminate these defects in the production process will also bring a great burden to the production process. . In particular, as the val...

The globe valve and the gate valve have a certain similarity in appearance, and as both valves have the role of cutting off in the pipeline, Let's see what the difference is between the globe valve and the gate valve?
1. working principles
Whenever the globe valve opens ...
Both the Y-type filter and the T-type filterare devices that filter impurities in the pipeline, and they can play a better filtering effect in the pipeline.
The following will introduce their characteristics.
Features Y-type filter :
1. Advanced structure
2. Low resistance
3. Easy to rinse
4, can...
A gate valve is a used for medium connection and shut-off, but not for regulation. Compared with other valves, gate valves have a wider range of combined applications in terms of pressure, working oil, design pressure and temperature.
According to the thread position of ...
1. Appearance
1.1. The floating ball valve and the trunnion mounted ball valve are still easy to distinguish in appearance. If the valve body has a lower fixed shaft, it must be a trunnion mounted ball valve. (You can refer to the appearance of the ball valve from RXVAL Valves).
1.2. If there is...
Both meat seat ball valves and soft seat ball valves are more common ball valves, and there are many differences between them.
1. Structure
The meat seat ball valve refers to the seal between metal and metal, and the sealing ball and seat are both metal. The seat of ...
What the design of Triple Offset Butterfly Valve ?
With the triple offset butterfly valve there are three offsets. Two are placed in a similar position to the double offset butterfly valve, while the third offset is the geometry of the seating surface, creating a type ...
If the valve leaks, first we need to find the cause of the valve leakage, and then formulate a valve maintenance plan according to different reasons. The following are the common valve leakage causes and solutions.
1.Body and Bonnet Leaks
Reason:
①The casting quality of ...
Preparation before installation:
1. Ensure that the pipeline at the installation position of the ball valve is in the coaxial position, and the two flanges on the pipeline should be kept parallel to confirm that the pipeline can bear the weight of the ball valve itself. If it is found that the p...
Floating ball valve design
A floating ball valve named because ball-like sphere that “floats” freely inside the valve’s body, which is compressed between two flexible seats while suspended in liquid. What a floating ball valve normally does during operation is float slightly downstream, which cau...
1. Principle:
Ball Valve:The opening and closing part of the ball valve is a sphere, and the purpose of opening and closing is realized by rotating the sphere 90° around the axis of the valve stem. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium o...
