Abstract

This invention provides a three-dimensional flow field effect condensate trap, comprising: a housing with a storage chamber inside; a nozzle disc dividing the storage chamber into an upper separation chamber and a lower drainage chamber; a Venturi nozzle, the straight end of which connects to the separation chamber, and the tapered end of which connects to the drainage chamber; and an auxiliary drainage component configured to increase the drainage flow rate when the water level in the separation chamber exceeds a set threshold. The beneficial effects of this invention are: steam mixed with condensate enters the separation chamber from the inlet pipe, and the condensate enters the drainage chamber through the Venturi nozzle. Under the Venturi effect, the condensate evaporates rapidly, causing an increase in air pressure within the drainage chamber. Under the pressure within the drainage chamber, the condensate flows to an external pipeline for recovery. When system fluctuations occur and the condensate level in the separation chamber exceeds the set threshold, the auxiliary drainage component assists in drainage, increasing the condensate trap's ability to cope with system fluctuations and ensuring the normal operation of the system.

Description

Technical Field

[0001] This invention belongs to the field of steam trap technology, and in particular relates to a steam trap with a three-dimensional flow field effect. Background Technology

[0002] A steam trap is a device used to control the discharge of moisture or condensation in a piping system. Its main function is to prevent the accumulation of water or condensation in the piping system and to remove it promptly, thus maintaining the normal operation and effectiveness of the system. The functions of a steam trap include: Removing moisture and condensation: Moisture and condensation in a piping system can negatively impact its normal operation, such as causing blockages and corrosion. Steam traps can automatically detect and remove this moisture and condensation, keeping the inside of the pipes clean and unobstructed. Protecting equipment and pipes: The accumulation of moisture and condensation can damage pipes and equipment, such as causing corrosion and blockages. Steam traps remove these harmful substances promptly, reducing damage to equipment and pipes and extending their service life. Saving energy: The presence of moisture or condensation in a piping system leads to energy loss, such as heat loss and a drop in fluid pressure. Steam traps remove these harmful substances promptly, reducing energy loss and improving the energy efficiency of the piping system.

[0003] Traditional steam trap types: Diaphragm type: The key component is a metal diaphragm filled with a liquid whose vaporization temperature is lower than the saturation temperature of water. The valve's opening and closing is controlled by the evaporation of the liquid within the diaphragm as it changes with the vapor temperature. Inverted bucket type: An inverted bucket inside acts as the level sensor. The inverted bucket connects to a lever that actuates the valve core. Due to the numerous connecting parts, its sensitivity is not as high as that of a float-type steam trap. Bimetallic strip type: A bimetallic strip temperature sensor electronic component actuates the valve core to open and close the valve. Thermodynamic type: The valve contains a movable pump casing, which is both the sensitive element and the mechanical actuator. Venturi steam traps operate based on the Venturi effect, where the flow velocity increases and the pressure decreases as fluid passes through a contraction section. It typically consists of a specially shaped pipe with both contraction and expansion sections. When condensate accumulates in the pipe, it flows along the pipe. When the condensate enters the contraction section of the Venturi steam trap, the increased flow velocity and decreased pressure cause the valve to open, discharging the condensate. Steam or gas maintains a high velocity and pressure at the expansion cross-section and is shut off by the valve to prevent its loss. Current Venturi steam traps have the following problems: First, they lack a rapid drainage structure. When an anomaly occurs in the steam system and the condensate volume suddenly increases, the fixed drainage flow rate of the steam trap under the Venturi effect leads to poor condensate drainage, or even condensate backflow, severely affecting the normal operation of the system. Second, the maximum condensate flow rate of the steam trap cannot be adjusted, thus limiting its application range. Summary of the Invention

[0101] Work process:

[0102] In this scheme, steam mixed with condensate enters the separation chamber through the inlet pipe 101. Under the influence of gravity, the condensate enters the bottom of the separation chamber (located outside the buffer chamber). The condensate then enters the drain chamber through the Venturi nozzle 3. Under the Venturi effect, the condensate evaporates rapidly, causing an increase in the gas pressure inside the drain chamber. When the gas pressure in the drain chamber exceeds the steam pressure of the separation chamber, the condensate will no longer flow into the drain chamber. Under the pressure inside the drain chamber, the condensate flows through drain channel 201, connecting pipe 8, and drain channel 102 to the external pipeline for recycling. When the system... When fluctuations occur, the amount of condensate in the separation chamber suddenly increases until it exceeds the set threshold. At this time, the water level in the separation chamber is higher than the overflow hole 901, and the condensate enters the buffer chamber. Under the action of buoyancy, the float 401 drives the sealing plug 403 to move upward, opening the upper opening of the auxiliary drain pipe 404. The condensate in the buffer chamber enters the drain chamber through the auxiliary drain pipe 404, and then flows to the external pipeline for recycling through the drain channel 1 201, the connecting pipe 8, and the drain channel 2 102. By setting the auxiliary drain component 4, the ability of the steam trap to cope with system fluctuations is increased, ensuring the normal operation of the system.
