Application of Pressure Relief Valve in textile production

In textile production, the drying method of sizing machines is to use drying cylinder heating. Its working principle is that the wet sizing yarn is in direct contact with the surface of the high-temperature metal drying cylinder. The surface of the drying cylinder obtains heat and transfers it to the surface of the sizing yarn, so that the moisture contained in the sizing yarn is continuously vaporized, the moisture regain rate of the sizing yarn is continuously reduced, and the surface of the sizing yarn is gradually formed. Serosa. A layer of condensed water formed on the inner surface of the drying cylinder adheres to the inner wall of the drying cylinder. The condensed water accumulated at the lower end of the drying cylinder is discharged through the drain trap. Therefore, the correct selection and daily maintenance of the Pressure Relief Valve are particularly important.

In order to ensure that the condensed water in the drying cylinder can be discharged in time, the method of increasing the steam pressure is usually adopted. In this way, a large amount of steam is wasted, and the safe use of the drying cylinder cannot be guaranteed. Therefore, in order to make good use of the drying drum sizing machine and achieve the goals of good sizing quality and low energy consumption, the correct selection of Pressure Relief Valve is crucial, and this is often ignored by sizing machine manufacturers and users.
(1) The steam pressure of the drying cylinder cannot be stable and is relatively fluctuating. The Steam Trap is required to be able to adapt to the changing steam pressure.
(2) The speed of the sizing machine also changes. The speed may be fast, slow or stopped. The hydrophobic device must be able to adapt to the hydrophobic amount under different loads.
The biggest advantage of the Pressure Relief Valve is that it is not affected by fluctuations in pressure, temperature and condensate flow. It continuously drains water and drains water as soon as it is present. The minimum subcooling degree is 0°C, which can enable the heating equipment to achieve optimal working efficiency; the valve of the Pressure Relief Valve The seat is always below the liquid level, forming a water seal and no steam leakage; its low working pressure is 0.01Mpa, and the maximum back pressure rate is ≤85%; it has an exhaust device inside, and the Pressure Relief Valve uses advanced diaphragm components as automatic The air exhaust valve can automatically eliminate non-condensable gases. It is very sensitive, has high working quality and long service life. Ideal Pressure Relief Valve for heating equipment.
