Description

Technical Field

[0001] The utility model relates to steam trap technology, in particular to a special energy-saving steam trap for steam. Background Art

[0002] Energy-saving steam traps are used in steam systems to effectively remove condensed water while retaining steam, thereby improving the thermal efficiency of the system and reducing energy consumption. Energy-saving steam traps are widely used in various occasions that require steam heating and insulation, such as steel, chemical, automobile, pharmaceutical, food and beverage, papermaking and other industries. They play an important role in these industries, helping to improve production efficiency, reduce energy consumption and protect the environment.

[0003] In the existing steam trap product structure, the float is horizontally located parallel to the drain port. Under the influence of the buoyancy of water, the float rises, the drain port valve opens, and water is discharged from the drain port. At the same time, the float falls, and the drain port valve closes. During this process, steam and water are discharged from the drain port, resulting in energy loss.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a steam-specific energy-saving steam trap to overcome the above technical problems existing in the existing related technology.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0007] A special energy-saving steam trap for steam comprises a valve body lower seat, the inner wall of the valve body lower seat is fixedly connected with a mounting seat, the upper part of the mounting seat is connected with a mounting frame through a screw, the mounting frame is connected with a floating plate through a rotating rod, and a limiting plate is fixedly installed under the floating plate;

[0008] A float is fixedly arranged above the floating plate, and a plurality of mounting holes are opened on one side of the lower seat of the valve body. The inner wall of one mounting hole is connected with a drain pipe, one end of which is connected to the mounting seat, and a drain port is opened on the mounting seat.

[0009] Furthermore, in order to improve the sealing performance of the flange connection, the upper part of the valve body lower seat is connected to the valve body upper seat, the connecting end of the valve body upper seat is fixedly connected to the flange, and a sealing gasket is arranged on the flange.

[0010] Furthermore, in order to facilitate the staff to observe the water level in the steam trap, an auxiliary groove is opened on one side of the valve body upper seat, and a liquid level tube is installed on the inner wall of the auxiliary groove.

[0011] Furthermore, in order to improve the tightness between the valve body upper seat and the valve body lower seat, a plurality of connecting holes are provided on the valve body upper seat and the valve body lower seat, and the inner walls of the connecting holes are threadedly connected with fixing screws.

[0012] Furthermore, in order to improve the sealing performance between the valve body upper seat and the valve body lower seat, a sealing groove is provided above the valve body lower seat, and a sealing ring is installed on the inner wall of the sealing groove.

[0013] Furthermore, an auxiliary block is fixedly connected to one side of the valve body upper seat, and an auxiliary hole is opened on the auxiliary block.

[0014] The beneficial effects of the utility model are:

[0015] (1) By making the float slightly higher than the drain port, when the float is affected by the buoyancy of water, the water in the steam-specific energy-saving steam trap always submerges the drain port, making it impossible for steam to be discharged from the drain port, reducing the amount of water carried by the steam. The front and rear positions of the float can be changed to control the discharge volume of the steam-specific energy-saving steam trap.

[0016] (2) The fixing screws set on the upper and lower seats of the valve body make it easier for staff to maintain and disassemble the steam-specific energy-saving steam trap, thereby reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
