  • Detail

According to the phase change principle, this kind of steam trap relies on the different thermodynamic principles of the flow rate and volume changes when steam and condensate pass through, so that different pressure differences are generated up and down the valve disc, driving the valve disc to open and close the valve. Because the working power of the thermal steam trap comes from steam, the waste of steam is relatively large. It has simple structure, water hammer resistance, 50% maximum back, noise, frequent operation of valve plate and short service life

the thermal power steam trap has thermal power type. When the oil delivery valve is opened smaller (disc type), pulse type, orifice plate -

there is a movable valve plate in the thermal power steam trap, which is both a sensitive part and an action actuator. According to the different thermodynamic principles of the flow rate and volume changes of steam and condensate when passing through, different pressure differences are generated up and down the valve plate to drive the valve plate to open and close the valve. The steam leakage rate is 3%, and the undercooling degree is 8 ℃ -15 ℃

when the device is started, there is cooling condensate in the pipeline. The condensate pushes the valve plate open by the working pressure and discharges quickly. When the condensate is discharged, the steam is then discharged. Because the volume and flow rate of steam are larger than that of condensate, there is a pressure difference between the top and bottom of the valve disc, and the valve disc closes quickly under the suction of the steam flow rate. When the valve disc is closed, the valve disc is under pressure on both sides, and the stress area under the valve disc is less than the stress area above. Because the pressure in the steam chamber of the steam trap comes from the steam pressure, the stress on the upper part of the valve disc is greater than that on the lower part, and the valve disc is tightly closed. When the steam in the steam chamber of the steam trap cools down to condensate, the pressure in the steam chamber disappears. The condensed water pushes the valve plate open by the working pressure, and the condensed water continues to drain, and won the Platts Global Energy annual breakthrough solution award that year. It works circularly and discharges water intermittently
