Product Description

Product Description

Quantitative control is the key link of papermaking, the quality of material discharge directly affects the quality and pass rate of paper forming paper. The control accuracy of electric material door is one thousandth, can fine- tune the material door, so as to accurately control the quantitative. Electric door repeat accuracy is high, in the paper machine to change different varieties, easy operators will be the door one step to adjust in place, reduce loss of paper / reduce costs. System composition: electric door has electric adjustment quantitative valve and valve controller composition.

In a paper mill, it is very important to detect the flow of pulp entering the head box. This flow parameter directly participates in the control of the paper quantification. Due to changes in head box pressure and liquid level, the amount of pulp jetted onto the mesh through the lip plate will fluctuate. Therefore, controlling the stability of the head box pulp flow is vital to the control of the paper basis weight, and it will also directly affect the paper's quality. The final quality.      
Through the measurement of the thickness and moisture of the final finished paper, the flow of pulp is controlled, which is called the "quantitative control system", and is usually considered to be the most important part of the paper machine "QCS" system.

The measurement of pulp flow usually uses electromagnetic control valve system.

Our Advantages

Advantage of Valve:
1. Integral valve body without any pipe joints, so it is not affected by the stress of pipes or bolts, and because the valve body has no pipe joints, the pressure-resistant shell will not be affected by pressure "sudden changes";

2. With a V-shaped valve body, even in the case of small flow or high viscosity medium, it can also ensure the accuracy of control in the entire range;

3. The leak-proof and durable valve seat is lined with a stainless steel inner core PTFE cup or O-shaped sealing ring at its outer diameter. The valve seat is made of tungsten-cobalt cemented carbide with a larger cross-section, through an alloy bellows spring. Further enhance the structure of the valve seat;

4. When the valve is closed, a wedge-shaped shearing effect is generated between the V-shaped notch and the valve seat, which not only has the function of self-cleaning but also prevents the ball core from jamming. It is especially suitable for high viscosity, suspension, pulp, etc. Fiber medium occasions.
