Film cassette trap and dual metal trap
Working performance and service life |
| Film cassette trap and dual metal trap belong to the static type of trap heat, steam and condensate is caused by temperature difference of the deformation or expansion drive component heart valves open valve. Hot static type of trap for general subcooling 15 ° ~ 40 ° c, it can use part of the condensate, energy-saving thermal effect is good. Steam pipes, heating pipes, heating equipment, high temperature of heating equipment, small ideal trap. |
|
| 1, film cassette trap temperature membrane box filled with a temperature of the water vaporizing than saturated low temperature of liquid. Device just started, the liquid membrane box, heart valve in the condensation in the open position, When the water temperature rising gradually, the liquid film evaporation in box, box began to rise, drive valve diaphragm pressure to close direction, In the condensed water saturation temperature, trap began to close. Film cassette trap is 15 degrees Celsius degree for 30 ° c and two boxes of membrane, without artificial selection. |
|
| (1), double trap is metal pieces on both sides by double temperature by the heat-sensitive materials with different pieces of adjustable deformation, there are several groups of double symmetric metal together, the bending deformation temperature after heart toward the closed position. Dual metal trap with adjustment bolts, can adjust according to different requirements drainage temperature. |
|
| 2, the film cassette trap membrane box is sealed filling liquid temperature, temperature liquid membrane box, heat, temperature area, particularly sensitive time in high temperature conditions, also won't change subcooling. The bellows and valves are removable, has good compatibility, small volume, arbitrary Angle can be installed. The bellows, service life is long. |
|
| 2 pieces, double trap often in high temperature conditions, dual metal fatigue sex, are often after a period of time, the elastic metal with double gradually become weak, and not to adjust, life is 1 ~ 2 years. |
|
| 3 and film cassette trap temperature membrane box is always with steam pressure and temperature change and keep in regular subcooling range between, need not manual adjustment, very sensitive, high quality of work。 |
|
| 3 pieces, double trap in the working stress and temperature unstable conditions, need adjustment bolts, otherwise have often possible leakage. |
|
| 4 and film cassette trap is the key depends on the membrane of manufacturing technology and liquid formulation. "The British brand" film cassette trap is made of imported temperature control meter box, box membrane high sensitivity, reliable performance. |
|
| 4 pieces, double trap manufacturing process is simple, the main technical depends on the quality of products, metal double. Choose good imported double metal can prolong the service life of trap. |

Free float type of trap and thermodynamic type of trap
Working performance and service life |
| Free float type of trap |
Thermodynamic type of trap |
| (1), free float type of trap seat in the liquid surface, the water below are separated, leakage protection, water vapor rate to 0%. |
|
| 1, because of thermodynamic type of trap is using steam and condensate through the velocity and volume change when the different thermodynamics principle, make fluctuation produced different pressure valves, and must have the fresh steam discharge ability drive valve slice off the trap. National standards and qualification for 3-5% of the leakage rate of steam. |
|
| (2), free float type of trap condensation water level fluctuation to come to work, have water, the equipment is not always filled with fresh standing, steam, make the best of the thermal equipment. It can exhaust temperature water saturation, minimum subcooling 0 degrees Celsius. With the thermodynamic type of trap, can compare to improve equipment temperature 8 ~ 10 degrees, shorten the time of heating equipment, improve work efficiency。 |
|
| (2), thermal dynamic type of trap is discontinuous drainage, minimum subcooling for 8 ~ 10 Celsius temperature. Equipment often being part of the condensate, extending the heating time, relatively poor. |
|
| 3, free float type of trap heart valve is a fine grinding of stainless steel hollow balls, the sphere, and all available for sealing off by the trap of differential pressure, make the ball float valve with condensation skip to the wall, the spherical disc note for sealing, can not wear, service life is long, good quality trap usually use life can reach 10 years. |
|
| 3 and thermodynamic type of trap work moves every minute of 8 ~ 10 times, the movement is frequent, heart valves, the steam flow erosion wear fast, use short life, national standard service life for 1 year. |
|
| 4 and free float type of trap of advanced structure, the processing precision manufacturing cost is high, thermal dynamic type of trap 3 ~ 5 times. |
|
| 4 and thermodynamic type of trap of simple structure, small volume, low production cost. |
|
Example: a gymnasium, YongQiLiang for 500 kg/hour, selection of heating equipment DN25 1 free float type of trap.
A, free float type of trap of advanced structure, working steam leaking, steam leakage rate of 0%, fresh steam can all use.
B, free float type of trap can exhaust temperature water saturation, minimum subcooling 0 °, water drainage, equipment, not standing than using thermodynamic type of trap can improve equipment temperature 8 ~ 10 degrees, equipment, heat up fast, good effect, shorter working hours, improve work efficiency and product qualification.
C, free float type of trap minimum pressure from 0.01 Mpa 0.01 Mpa pressure within the scope of the highest temperature and pressure are not affected by the fluctuation of the continuous drainage, back-pressure rate than 85%. |
|
Example: a gymnasium, YongQiLiang for 500 kg/hour, choose 1 heating equipment DN25 thermodynamic type of trap.
A, thermodynamic type of trap work power comes from the steam, steam waste, national standard allows leakage rate of 3 ~ 5%, steam condenser leakage rate of 4% in for example calculation is as follows:
500 kg/h x 4 = 20 kg/hour
20 kg (= 48 kg / 24 hours a day
48 kilograms (30 days = 14400 kg/month
Steam by 110 yuan per ton
144 tons/x 110 yuan = 1584 yuan
Every year is 1584 yuan/month (12 = 19008 yuan
Through calculation of the above every year at least $19008 waste no use steam.
B, thermodynamic type of trap drains, continuous minimum subcooling for 8 ~ 10 degrees, equipment often standing, so the heat exchange efficiency is poor, lengthen working hours, the influence of work efficiency and product qualification.
C, thermodynamic type of trap the highest rate of 50% less pressure. |
|
| Through the comparison, more than one does not know than a fright, trap usually considered a small parts, without cause the attention of people. A big enterprise, if can trap scientifically and rationally choose, and energy saving potential is considerable. The trap must choose the best quality products, to the limited funds in the blade. Using high quality trap had to save energy and to improve production efficiency than buying the trap of investment to a few times or a hundredfold. Choose good quality traps can bring huge economic benefits. The trap of large quantity, used widely ignored, competent leadership should be highly valued. |
