Background

The steam trap is an important control valve which ensures the normal work of a steam system, smoothly recycles condensed water, prevents steam from overflowing and saves energy. On the one hand, the steam leakage can be prevented, the energy waste caused by excessive steam consumption is avoided, on the other hand, condensed water can be timely discharged, and the damage to pipelines caused by corrosion, steam pipeline water hammer and other phenomena is avoided. In the past, a general steam trap is generally adopted in the steam trap in the industrial production process for water-vapor separation. The conventional steam trap is very easy to damage under the impact of steam due to the fact that the movable parts are arranged inside the steam trap, the steam trap is often damaged in one year, the replacement frequency is very high, and therefore manpower and financial resources for maintenance are very high. In order to reduce the maintenance intensity and the production cost, some enterprises basically discharge directly under the two working conditions, so that a large amount of energy is wasted and the production environment is influenced. Also some enterprises install traditional type steam trap additional behind steam heater, because traditional type steam trap is not able to bear or endure the impact of the flow of steam and pressure variation, produce interior hourglass, if do not carry out professional detection, the confined system is that it is difficult to discover to leak in the steam trap steam, moves like this throughout the year, causes manufacturing cost to have a great increase.

The conventional steam trap is always used to cause air leakage, and the conventional steam trap is frequently replaced after the heater, so that the large maintenance workload is caused, the replacement cost is high, the installation or the cleaning is troublesome, the service life is long, the strong popularization is not facilitated, and the Venturi type steam trap needs to be designed urgently at present.
