Description

Technical Field

[0001] This utility model belongs to the field of condenser technology, and in particular relates to a liquid equalization mechanism for a tube box in a condenser. Background Technology

[0002] A tube box is installed at the end of the condenser shell. The tube box distributes the medium to several heat exchange tubes or collects the medium in the heat exchange tubes. The tube box is equipped with an inlet pipe and a drain pipe. Since a large number of heat exchange tube ports are connected to the tube box, the impact force and pressure generated by the liquid supply and drainage will cause problems with poor uniformity and stability.

[0003] Currently, liquid equalization plates can be welded and fixed to the inner wall of the pipe box at positions opposite to the inlet and outlet to serve as liquid equalization and buffering. However, since the liquid equalization plate is a perforated plate, the presence of holes makes it difficult to install and position it with the pipe box. Furthermore, once welded, the weld seam is prone to corrosion and rust, affecting the performance and positional stability. Summary of the Invention

[0004] The purpose of this utility model is to provide a liquid equalization mechanism for a condenser tube box. Through the design of the novel liquid equalization mechanism, it can play the roles of liquid equalization and buffering, improve the flow stability of the refrigerant, improve the stability of refrigerant input and output in the heat exchange tube, and improve the heat exchange effect of the condenser. At the same time, the designed liquid equalization mechanism can be installed and positioned from the outside of the tube box without welding, which is conducive to installation and disassembly and avoids the problems of easy rust and corrosion caused by welding, thus improving its positional stability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a liquid equalization mechanism for a tube box for a condenser, including a tube box body, tube openings and a liquid equalization mechanism body;

[0008] The liquid equalization mechanism body includes a liquid equalization cover, which is a hemispherical structure. The liquid equalization cover has several openings, and the diameter of the openings on the liquid equalization cover increases sequentially from the axis to the outer side.

[0009] An embedded ring is fixed at the end of the liquid equalization cap away from the arc portion. A gasket ring is provided at the edge of the embedded ring at the end away from the liquid equalization cap. A tube head is integrally connected to the end of the embedded ring away from the liquid equalization cap.

[0010] The liquid equalization cover is located inside the tube box, and the gap of the embedded ring is set inside the through port.

[0011] Both ends of the pipe opening are provided with external flanges. The pipe opening is fitted onto the pipe head. The pipe opening is fixed to the outside of the pipe box body by the external flange, the inner flange and fasteners. A pressure ring is provided on the inner side of the external flange at one end of the pipe opening. The pressure ring presses against the outer end face of the gasket.

[0012] Sealing gaskets are provided between the pressure ring and the washer ring, and between the washer ring and the flared neck.

[0013] Furthermore, the thickness of the gasket is consistent with the depth of the neck, and the outer surface of the gasket is flush with the outer surface of the tube box.

[0014] Furthermore, the inner side of the pipe opening near the pressure ring is provided with an inner recess, and the pipe opening gap is set inside the inner recess.

[0015] Furthermore, the inner flange is provided with several mounting ports, and the outer side of the pipe box is provided with several blind ports, and the blind ports are concentric with the mounting ports respectively.

[0016] Furthermore, the inner diameter of the tube head is the same as the inner diameter of the tube opening, and the end face of the tube head away from the liquid equalization cover is flush with the inner end face of the concave opening.

[0017] Furthermore, the liquid equalization mechanism body is provided with an anti-rust primer layer, and the outer surface of the anti-rust primer layer is provided with a topcoat.

[0018] This utility model has the following beneficial effects:

[0019] This invention, through the design of a novel liquid equalization mechanism, can play a role in liquid equalization and buffering, thereby improving the flow stability of the refrigerant, enhancing the stability of refrigerant input and output in the heat exchange tubes, and improving the heat exchange effect of the condenser. At the same time, the designed liquid equalization mechanism can be installed and positioned from the outside of the tube box without welding, which is convenient for installation and disassembly and avoids the problems of easy rust and corrosion caused by welding, thus improving its positional stability. Furthermore, since the liquid equalization mechanism can be installed and removed directly from the outside, it has the function of replacement and maintenance without removing the tube box, making the operation simple.
