Introduction and Application of High Pressure Steam Traps

High-pressure steam trap is used in high-pressure pipe network and equipment, can automatically discharge condensate, air and other non-condensable gas, and block water vapor leakage valve. According to the different working principle of high-pressure steam trap, steam trap can be turned into the following three types: Mechanical type: Rely on high-pressure steam trap condensate level changes in water and action, including: 1, Float: float closed Hollow sphere up float type: the float is open upward barrel open downward Float: the float is open downward barrel 2, the thermal static type: relying on changes in liquid temperature and action, including: bimetallic : Sensitive to the original bimetal pressure type: sensitive to the original bellows or ink cartridges, filled with volatile liquid inside 3, thermodynamic type: relying on the thermodynamic properties of the liquid changes. Disc type: Due to the same pressure, the flow rate of liquid and gas are different, resulting in different dynamic and static pressure to actuate the disc valve pulse: Due to the different temperatures of the condensate through the two series in series orifice Plate, sitting in the bipolar orifice between the different pressures, driving the valve action. Structure and working principle of high-pressure steam trap: Steam trap in the steam heating system to play the role of gas drainage, select the appropriate trap, the steam heating equipment to achieve maximum efficiency. In order to achieve the best results, we must conduct a comprehensive understanding of the performance of various types of traps, features. This type of valve in the pipeline should be generally horizontal installation. Trap a lot of varieties, each with different properties. The choice of traps, the first choice should be its characteristics to meet the best operation of steam heating equipment, and then consider other objective conditions, so you need to select the trap is correct and effective. Traps to be able to "identify" steam and condensate in order to play the role of gas blocking drainage. "Identifying" steam and condensate is based on three principles: density difference, temperature difference and phase transition. So according to three principles to create three types of trap: classified as mechanical type, thermal type, thermal type.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
