The function of a steam trap is to automatically remove condensate from heating equipment or steam piping without leaking steam. Because the trap has the function of blocking steam drainage, it can make the steam heating equipment evenly heated, make full use of the latent heat of steam, and prevent water hammer in the steam pipeline.

TrapsThe working principle is to take advantage of the density difference between steam and condensate, or to change the phase statePhysical properties, to promote the opening and closing of the valve to enter and dismantle the good line of work. Commonly usedTrapsThere are various types such as float type, bell float type, and thermodynamic type.

The steam trap is installed between the steam heating equipment and the condensate return header. When opened, the barrel is at the bottom and the valve is fully open. The condensate enters the trap and flows to the bottom of the barrel, fills the valve body, and completely submerges the lead barrel, and then the condensate is discharged to the return header through the fully open valve.

The main functions of a steam trap are:

1. The trap automatically excludes the steam condensate in the heating equipment or steam pipeline, and does not leak steam.

2. Because the steam trap has the function of blocking steam drainage, it has been widely used, for example: the steam trap is used for condensate in steam heating equipment such as surface heat exchangers, which can effectively prevent steam leakage and improve the thermal efficiency of the heat exchanger.

3. The trap is used for the hydrophobic ** of the heating joint box and the hydrophobic ** of the steam pipeline. It is possible to reduce the steam water in the steam system.

loss, improve economic efficiency.

4. Use the steam trap to discharge the condensate in the steam pipeline to prevent the steam impact in the steam pipeline and ensure the safe operation of the steam system.

The function of the steam trap is to discharge the condensate generated in the steam system as soon as possible; At the same time, it can prevent steam leakage.

The working principle is to use the density difference between steam and condensate, or change the physical properties of the phase to promote the opening and closing of the valve to work. Commonly used traps include float type, bell float type and thermodynamic type.

For example, the float type is when the water in the valve gradually accumulates, the float opens the drainage channel in the valve with the rise of the liquid level, and discharges the drain under the action of steam pressure in the valve, and the float descends after the water level drops, closing the drainage channel.

The function of the steam trap is to drain the steam and block the steam, discharge the condensate in the steam pipeline out of the pipeline, and at the same time prevent steam leakage. Resources.

<>1 Steam traps are installed between the steam heating equipment and the condensate return header. When starting, the barrel is at the bottom and the valve is fully open. The condensate enters the trap and flows to the bottom of the barrel, filling the valve body, completely submerging the barrel, and then the condensate is discharged to the return header through the fully open valve.

2 Steam also enters the trap from the bottom of the barrel and occupies the top of the barrel, creating buoyancy. The barrel slowly rises and gradually moves the lever in the direction of the seat until the valve is completely closed. Air and carbon dioxide gases pass through the small pimp hole of the barrel and collect at the top of the trap.

The steam that exits from the vent hole condenses due to heat dissipation from the trap.

3 When the incoming condensate starts to fill the barrel, the barrel starts to exert a pull force on the lever. As the condensate level continues to rise, the resulting force increases until it is possible to overcome the pressure difference and open the valve.

When the ballast 4 valve begins to open, the differential pressure acting on the disc decreases. The barrel body will be rapidly lowered so that the valve is fully open. The non-condensable gas that accumulates on the top of the trap is discharged first, and then the condensate is discharged.

When the water flows out of the barrel, the dirt flows out of the trap together. At the same time as the condensate is discharged, the steam starts to enter the trap again, and a new cycle begins.

<> most basic principle of discharging condensate from a steam trap is to use the weight difference and temperature difference between steam and water to achieve the purpose of drainage.

1.Functions of Steam Traps: Only steam is required to use and utilize the equipment used for steam travel. Condensate is bound to be produced in such equipment, and condensate becomes a harmful fluid, mixed with air and other non-condensable gases, which can be the cause of equipment failure and reduced performance.

In this case, the most important functions of a steam trap are the following three aspects:

1) It can quickly remove the condensate generated.

2) Prevent steam leakage.

3) Remove air and other non-condensable gases.

2.Exclude the necessity of condensate.

1) Prevent water hammer. First of all, from a safety point of view, if there is condensate in the steam pipeline, the high-speed flowing steam pushes the condensate accumulated together, so that the condensate makes a strong impact on the pipe wall, valves and steam use equipment, and often brings a large impact. This phenomenon is called water hammer, also known as water hammer or water hammer.

When water hammer is strong, it can cause damage or destruction at pipe bends and valves.

Secondly, water hammer is not only due to the presence of condensation. Due to improper installation and use of the boiler, sometimes the water in the boiler enters the steam and is carried to the pipeline. Therefore, if the structure of the Peib boiler is defective or improperly used, the water level of the boiler will be too high, so the steam humidity of the boiler is too large, and the formation rate of condensate is accelerated, which is also a cause of water hammer.

Generally, in the saturated steam of the boiler**, the humidity should be below 4%; If it's 6%, the humidity is high; If it reaches 10%, the humidity is too high. In the case of high or excessive humidity, it is necessary to modify the structure of the boiler or solve the problems of installation.

Pro, air traps and steam traps are sealed differently. The sealing of the air trap is achieved by a metal seal between the spool and the seat, and when the spool is closed, the contact area between the metal sealing surfaces is very small, which can achieve a very good sealing effect. The sealing of the steam trap is achieved by the soft seal between the valve core and the valve seat, and the soft sealing material is usually rubber or PTFE and other materials, which can maintain good sealing performance in the environment of high temperature and high pressure.

It should be noted that since the sealing material of the steam trap is usually rubber or PTFE and other materials, it is necessary to pay attention to the corrosion resistance and high temperature resistance of the material during use, so as not to affect the sealing effect.

Summary. Steam trap is a kind of energy-saving device widely used in industrial production, its main function is to use its internal sensitive elements, can automatically control the liquid level inside the steam pipeline and equipment, so that the excessive condensate in the pipeline can be discharged in time, prevent the steam pipeline, equipment, etc. from being eroded and damaged by the wet steam in the system, etc., ensure the stable and safe operation of the system, realize the energy-saving control of the steam system, shorten the production time, improve the production efficiency, and reduce the production cost.

Hello, AF15FR-GH Float Trap Valve Steam Trap Trap is suitable for low-pressure steam thermodynamic trap has close to continuous drainage performance, its application range is large, and it can generally be selected. However, the maximum allowable back pressure shall not exceed 50% of the inlet pressure, and the minimum working pressure shall not be lowerOrifice traps and thermostatic traps are not suitable for use in steam turbines, steam pumps, or steam mains with separators, even in turbine housings, because they do not immediately remove condensate.

Aforementioned. In the case that the condensate must be eliminated immediately after it is formed, it is not advisable to choose an orifice trap, and a thermostatic bellows trap cannot be selected, because both require a certain degree of subcooling (about the number of rubber cracks should not be used when the condensate load changes to less than 15% of the rated maximum discharge, because it will cause the leakage loss of some fresh steam under low load.
