Problems solved by technology

However, in the process of conveying condensed water, if high-pressure and high-temperature steam enters, water vapor mixing or condensed water mixing at different pressures and temperatures will occur, and water hammer is prone to occur, which will cause vibration and deformation of the pipeline. pipeline damage
Therefore, the displacement of the trap must meet the actual working conditions, and the actual working conditions are very complicated, and a single-caliber steam trap cannot fully meet the requirements of all working conditions.

Embodiment 1

[0023] A condensate drainage system for reducing the occurrence of water hammer, used for condensate drainage of heat exchangers, such as figure 1 As shown, it includes a controller, a pre-valve condensate pipe 1 used to connect with the heat exchanger, two float traps arranged in parallel on the pre-valve condensate pipe 1 and connected with each float trap respectively. The condensed water pipeline 4 behind the valve is provided with a control valve at the condensed water inlet of each ball float trap, and the control valve is connected with the controller by communication. The two ball float traps are the large diameter ball float trap 2 and the small diameter ball float trap 3. The valve seat of the large diameter float trap 2 is composed of an upper valve seat and a lower valve seat. Double valve seat, the valve seat of the small diameter ball float trap 3 is a single valve seat, the condensate pipe 1 in front of the valve is set horizontally, the condensation of the larg...

Abstract

The invention relates to a condensation water discharge system for reducing the occurrence of water hammer. It's used for discharge of condensed water from heat exchanger, including a controller, a pre-valve condensation water pipe (1) connected to a heat exchanger, two floating ball type water drain valves arranged in parallel on the pre-valvet condensation water pipe (1) and behind-valve condensation water pipes (4) connected respectivedly with each floating ball type steam trap. The condensed water inlet of each floating ball type steam trap is respectively provided with a control valve, and the control valve is communicated with the controller. Compared with the prior art, the present invention takes advantages in its wide application range, its high drainage function according to different working conditions, as well as its safety and reliability, and the like.

Description

technical field [0001] The invention belongs to the technical field of condensed water discharge, and in particular relates to a condensed water discharge system for reducing water hammer phenomenon. Background technique [0002] Nowadays, in the field of steam transportation technology, float traps are widely used by people. They are mainly used in steam pipe networks and equipment, which can automatically discharge condensed water, air and other non-condensable gases, and prevent water steam from leaking. However, in the process of conveying condensed water, if high-pressure and high-temperature steam enters, water vapor mixing or condensed water mixing at different pressures and temperatures will occur, and water hammer is prone to occur, which will cause vibration and deformation of the pipeline. Pipeline damage. Therefore, the displacement of the trap must meet the actual working conditions, but the actual working conditions are very complicated, and a single-caliber s...
