With the progress and continuous reform of the times, my country's valve products have also been innovated with the change of the times. At present, in the valve market where environmental protection and safety are becoming more and more demanding, t...

The ball valve and the plug valve are the same type of valve, only the closing member of which is a ball, and the ball rotates around the center line of the valve body to open and close a valve. The ball valve is mainly used in the pipeline to cut, d...

Valves are generally divided into automatic valves and actuated valves. Automatic valves (such as safety valves, pressure reducing valves, steam traps and check valves) rely on changes in the medium pressure of the equipment or pipeline to achieve th...

In pipeline engineering, do the symbols of pipeline diameter DN, De, D, d, and Φ make it clear to everyone, let’s understand their meaning and differences together. 1. The meaning of DN, De, D, d, Φ Generally speaking, the diameter of a pipe can be d...

The radiator thermostatic valve is correctly installed in the heating system, and the user can adjust and set the temperature according to the requirements of room temperature. This ensures that the room temperature of a room is constant, avoiding th...

The vertical imbalance of the single-tube system is characterized by the higher the flow rate and the higher the room temperature at the end room; the smaller the flow rate, the lower the room temperature at the end room. According to this thermal ch...

CPVC pipe is a kind of plastic pipe with good heat resistance obtained by processing chlorinated polyvinyl chloride. Chlorinated polyvinyl chloride (CPVC) is a product of further chlorination modification of polyvinyl chloride (PVC). Its chlorine con...

The high resistance of the temperature control valve is determined by the adjustment characteristics of the radiator. The design of the temperature control valve must be considered in order to avoid the situation of insufficient capital pressure. Tem...

The impact of production rate on production The vehicle speed is too high: 1. The internal frictional shear force and thus a large amount of "heat accumulation" may occur between the nip, resulting in the entire molecular chain orientation (the molec...

Temperature control in the user's room is achieved by the radiator thermostatic control valve. The radiator thermostatic control valve is composed of a thermostat controller, a flow regulating valve and a pair of connecting members, wherein the core ...

Flow: plastic deformation (real flow); elastic deformation (non-real flow) Time-temperature equivalence: changing the temperature effect is equivalent to changing the time scale During production, it was found that after speed reduction, when there i...

According to the requirements of use, the type of pressure reducing valve and the accuracy of pressure regulation are selected, and then the diameter is selected according to the required maximum output flow rate. When determining the source pressure...
