Description

Technical Field

[0001] This utility model relates to the field of steam trap technology, specifically a steam trap diaphragm box with a heat dissipation structure. Background Technology

[0002] A steam trap, also known as a condensate drain or condensate drainer, is used in both steam and gas systems. It is installed at the end of steam-heated pipes to continuously drain condensate from the pipes. The diaphragm is the switch that controls the opening and closing of the steam trap, playing a crucial role in its operation.

[0003] A search revealed Chinese patent CN115654354A, which discloses a diaphragm box for a steam trap, comprising a diaphragm assembly, a top cover, and a base. The top cover is connected to the base, and its outer edge is connected to the outer edge of the base. An inner cavity is formed between the top cover and the base. The diaphragm assembly includes an outer membrane layer and a liquid that expands upon heating. The outer membrane layer is connected to the base, and the liquid fills the outer membrane layer. The top cover has a mounting hole in the center communicating with the inner cavity, and heat dissipation holes around its perimeter communicating with the inner cavity. This invention controls the opening or closing of the steam trap body through the diaphragm assembly, and the heat dissipation holes around the top cover help dissipate heat from the diaphragm assembly.

[0004] However, the heat dissipation holes in the diaphragm box of this utility model cannot be opened and closed as needed, causing the heat dissipation holes to remain open. Over time, this leads to a large amount of impurities or dust entering, which seriously affects the use of the equipment. At the same time, impurities can clog the heat dissipation holes, thereby affecting the heat dissipation quality and failing to meet the usage requirements. Therefore, a diaphragm box with a heat dissipation structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hydrophobic valve diaphragm box with a heat dissipation structure, which has the advantages of strong practicality and easy heat dissipation as needed, and solves the problem that the heat dissipation holes cannot be opened and closed as needed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydrophobic valve diaphragm box with a heat dissipation structure, comprising a hydrophobic valve body, an upper cover and a bottom ring plate distributed vertically, an outer membrane layer installed on the bottom ring plate near the upper cover, and a thermally expanding liquid filled inside the outer membrane layer. The upper cover has an installation hole and a heat dissipation hole inside, and the upper cover has a shielding structure for shielding the heat dissipation hole inside.

[0007] The shielding structure includes a shielding disc rotatably mounted inside the upper cover and shielding the heat dissipation holes, a slide rod fixedly mounted on the upper surface of the shielding disc and slidably connected to the inside of the upper cover, and a driving component disposed on the shielding disc and the outside of the upper cover.

[0008] The driving component includes a motor, a transmission gear fixedly mounted on the motor output shaft, and a driven gear fixedly mounted on the outer wall of the shielding disc and meshing with the transmission gear.

[0009] Furthermore, a cavity is formed between the upper cover and the bottom ring plate, the heat dissipation hole is connected to the cavity, and the mounting hole is connected to the cavity.

[0010] Furthermore, the number of heat dissipation holes is six, and the six holes are equidistantly distributed around the perimeter of the top cover.

[0011] Furthermore, a dustproof structure is provided on the outside of the heat dissipation hole. The dustproof structure includes a frame that is bolted to the outside of the upper cover and located at the edge of the heat dissipation hole. A dustproof net is fixedly installed on the inner side of the frame.

[0012] Furthermore, the upper cover has an internal groove that matches the sliding rod, and the sliding rod is slidably connected to the groove.

[0013] Furthermore, there are two slide rods, which are symmetrically arranged, and the slide groove is annular in shape.

[0014] Furthermore, an mounting plate is fixedly installed on the outer wall of the upper cover, the motor is fixedly installed on the outside of the mounting plate, and the interior of the shielding disc has through holes corresponding to the six heat dissipation holes.

[0015] Compared with the prior art, the present invention provides a hydrophobic valve diaphragm box with a heat dissipation structure, which has the following advantages:

[0016] 1. The diaphragm box with heat dissipation structure can block the heat dissipation holes as needed, so that the heat dissipation holes can better dissipate heat. This achieves advantages such as high practicality and convenient heat dissipation as needed, and solves the problem that the heat dissipation holes cannot be opened and closed as needed.

[0017] 2. The diaphragm box with heat dissipation structure allows the shielding disc to move linearly through the installation of the sliding rod and the sliding groove, improving the stability of the shielding disc during rotation. At the same time, the dustproof net can block the heat dissipation holes, preventing impurities and dust from entering, and greatly improving the heat dissipation effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1 and Figure 4 A hydrophobic valve diaphragm box with a heat dissipation structure includes a hydrophobic valve body 1, an upper cover 3 and an annular base plate 2 distributed vertically, an outer membrane layer 4 installed on the side of the annular base plate 2 near the upper cover 3, and a thermally expanding liquid 5 filled inside the outer membrane layer 4. The upper cover 3 has an installation hole 6 and a heat dissipation hole 8 inside. A cavity 7 is formed between the upper cover 3 and the annular base plate 2. The heat dissipation hole 8 communicates with the cavity 7, and the installation hole 6 communicates with the cavity 7.

[0026] There are six heat dissipation holes 8, which are equidistantly distributed around the perimeter of the upper cover 3. The thermal expansion liquid 5 is a mixture of silicone oil and alcohol. The outer film layer 4 is a stainless steel layer.

[0027] In this embodiment, there is a gap between the outer membrane layer 4 and the steam trap body 1 during use. When heated, the thermally expanding liquid 5 expands and presses the outer membrane layer 5 outward. The outer membrane layer 4 expands outward and blocks the steam trap body 1, thereby causing the steam trap body 1 to close. The heat dissipation hole 8 is used to help the outer membrane layer 4 dissipate heat. When the outer membrane layer 4 returns to normal temperature, the thermally expanding liquid 5 contracts, the outer membrane layer 4 returns to its original state, and the steam trap body 1 opens again, thereby realizing the opening or closing of the steam trap body 1.

[0028] It should be noted that the valve body 1, the outer membrane layer 4, and the thermally expanding liquid 5 are all conventional technologies known to the public in the prior art, so their specific structural composition and working principle will not be described in detail in this article.

[0029] Example 2:

[0030] Please see Figure 2 and Figure 3 Based on Embodiment 1, in this embodiment, the upper cover 3 is internally provided with a shielding structure to block the heat dissipation holes 8. The shielding structure includes a shielding disc 11 rotatably mounted inside the upper cover 3 and blocking the heat dissipation holes 8, a slide rod 12 fixedly mounted on the upper surface of the shielding disc 11 and slidably connected to the interior of the upper cover 3, and a driving component disposed on the shielding disc 11 and the exterior of the upper cover 3. The driving component includes a motor 14, a transmission gear 15 fixedly mounted on the output shaft of the motor 14, and a driven gear 16 fixedly mounted on the outer wall of the shielding disc 11 and meshing with the transmission gear 15. The motor 14 drives the transmission gear 15 to rotate, and the rotation of the transmission gear 15 meshes with the driven gear 16, causing the shielding disc 11 to rotate, so that the through hole 13 is no longer on the same axis as the heat dissipation holes 8. At this time, the shielding disc 11 blocks the heat dissipation holes 8. When the through hole 13 and the heat dissipation holes 8 are on the same axis, the heat dissipation holes 8 can perform heat dissipation normally.

[0031] It should be noted that the upper cover 3 has a groove 18 inside that matches the sliding rod 12, and the sliding rod 12 is slidably connected to the groove 18. There are two sliding rods 12, and the two sliding rods 12 are symmetrically arranged. The groove 18 is annular. Through the installation of the sliding rod 12 and the groove 18, the blocking disc 11 can be linearly displaced, improving the stability of the blocking disc 11 when it rotates.

[0032] The upper cover 3 has a mounting plate 17 fixedly installed on its outer wall, and the motor 14 is fixedly installed on the outside of the mounting plate 17. The shielding disc 11 has through holes 13 corresponding to the six heat dissipation holes 8 inside. The upper cover 3 has a sliding opening on its side for meshing the drive gear 15 and the driven gear 16.

[0033] In this embodiment, a dustproof structure is provided on the outside of the heat dissipation hole 8. The dustproof structure includes a frame 9 that is bolted to the outside of the upper cover 3 and located at the edge of the heat dissipation hole 8. A dustproof net 10 is fixedly installed on the inner side of the frame 9. The dustproof net 10 can block the heat dissipation hole 8, preventing impurities and dust from entering, and greatly improving the heat dissipation effect.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the motor 14 drives the transmission gear 15 to rotate. The rotation of the transmission gear 15 meshes with the driven gear 16, causing the shielding disc 11 to rotate, so that the through hole 13 is no longer on the same axis as the heat dissipation hole 8. At this time, the shielding disc 11 blocks the heat dissipation hole 8. When the through hole 13 and the heat dissipation hole 8 are on the same axis, the heat dissipation hole 8 can perform heat dissipation normally. The dustproof net 10 blocks the through hole, thereby preventing a large amount of impurities and dust from entering and improving the heat dissipation effect.

[0036] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
