Description

Technical Field

[0001] The present application relates to the field of HVAC engineering technology, and in particular to a HVAC condensate pipe drainage anti-microbial sealing drainage device. Background Art

[0002] The main reason why the joints of the condensate pipes in the HVAC system need to be sealed is to prevent the generation of condensate water from causing water accumulation, scaling, odor, microorganisms and viruses in the pipes. Maintaining an airtight connection inside the pipes with the air-conditioning box effectively reduces the generation of water accumulation, scaling, odor, microorganisms and viruses that do not meet GMP requirements.

[0003] In the existing technology, the generation of scaling, odor, microorganisms and viruses cannot be effectively solved by mainly using a single one-way valve and a water trap. Affected by unstable factors such as the installation workers and the working environment, the condensate generated by the running air-conditioning unit cannot be effectively isolated and protected. According to the actual use situation on site, it cannot be effectively protected from external dust pollution, thereby affecting the final use effect. Therefore, the present application provides a sealing device for condensate water used in HVAC engineering condensate pipes to prevent scaling, odor, microorganisms and viruses. Utility Model Content

[0004] In order to make up for the above deficiencies, the present application provides a HVAC condensate pipeline drainage anti-microbial sealing drainage device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention to solve the technical problem is:

[0006] A microbial-proof sealed drainage device for HVAC condensate pipe drainage includes a vertical pipe and a horizontal pipe fixedly connected to the bottom end of the vertical pipe, the outer end of the horizontal pipe is integrally formed with an extension pipe, and a drainage device is installed inside the horizontal pipe and the extension pipe. The drainage device consists of a non-return mechanism and a non-powered self-weight drainage mechanism, the non-return mechanism is installed inside the horizontal pipe and the extension pipe, and the non-powered self-weight drainage mechanism is integrally welded to one end of the bottom inside the horizontal pipe.

[0007] Furthermore, the non-return mechanism includes a flap valve I and a flap valve II, the top of the flap valve I is hingedly connected to the top inner end of the horizontal tube, and the outer wall is in contact with the inner wall of the horizontal tube, and the top of the flap valve II is hingedly connected to the top inner end of the extension tube, and the outer wall is in contact with the inner wall of the extension tube.

[0008] Furthermore, the bottom ends of the horizontal tube and the extension tube are provided with two protrusions, and the two protrusions are respectively fitted with the same side of the flap valve I and the flap valve II.

[0009] Furthermore, the flap valve I and the flap valve II are installed on the same circuit to form a double layer of protection.

[0010] Furthermore, the unpowered self-weight drainage mechanism includes an automatic drainage connecting pipe, a sealing cover, a float, a water inlet I and a water inlet II. One end of the automatic drainage connecting pipe is integrally formed with the outer bottom end of the horizontal pipe, and the interiors are interconnected. The sealing cover is seamlessly welded to one end of the interior of the horizontal pipe and covers the interface of the automatic drainage connecting pipe. The float is arranged inside the sealing cover. The water inlet I is opened at the top of the sealing cover, and the water inlet II is opened at the bottom end.

[0011] Furthermore, a water inlet interface is integrally formed at the top of the vertical pipe.

[0012] Furthermore, the outer end of the extension pipe is integrally formed with a drainage interface.

[0013] The utility model has the following beneficial effects:

[0014] 1. This utility model utilizes built-in check mechanisms (including flap valves I and II) in the cross pipe and extension pipe to effectively prevent condensate backflow, reducing the time condensate remains in the pipes, thereby significantly reducing the risk of microbial growth within the pipes. This design helps maintain the sanitation of the air conditioning system and extend the service life of the equipment.

[0015] 2. This utility model's flap valves I and II are installed on the same circuit, creating a double layer of protection and significantly enhancing backflow prevention. This design ensures that even if one valve fails, the other continues to function, preventing condensate from flowing back. The flap valves open to facilitate condensate flow in response to condensate inflow and outflow, and automatically close when condensate stops flowing. This prevents environmental fluctuations, such as dust, scaling, odor, and the presence of microorganisms and viruses, which can impact the production environment and GMP control standards.

[0016] 3. This new, unpowered, self-weighted drainage mechanism operates after the flap valve automatically closes. When the water level drops to a point where gravity is less than buoyancy, the float automatically opens, allowing condensate to drain. Once the condensate is drained, the float resets, preventing environmental changes that could cause dust, scaling, odor, and microbial viruses that could impact the production environment and GMP control indicators.

[0017] 4. The unpowered, self-weighted drainage mechanism of this utility model is installed within the horizontal pipe. When the flap valve automatically closes, condensate drainage essentially ceases. Once the liquid level inlet of the unpowered, self-weighted drainage mechanism is exposed, the condensate within the automatic device automatically decreases to a point where its weight is less than the buoyancy of the float. The float then rises due to its own buoyancy, and the condensate is automatically discharged through water inlet II and the automatic drain connection pipe. When the condensate within the U-shaped storage space is completely drained, the float falls back due to its own gravity to the internal condensate outlet of the automatic drain connection pipe, sealing the internal condensate outlet with its own gravity.

[0018] 5. The design of the water inlet interface and the drainage interface of the utility model can be matched with the size of the condensate drainage pipe and has high adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0025] Example:

[0026] See also Figure 1、 Figure 2 、 Figure 3 A microbial-proof sealed drainage device for HVAC condensate pipe drainage includes a vertical pipe 1 and a horizontal pipe 2 fixedly connected to the bottom end of the vertical pipe 1, and an extension pipe 3 is integrally formed at the outer end of the horizontal pipe 2.

[0027] Among them, the vertical pipe 1 is the main component for collecting and initially guiding condensed water. The vertical pipe 1 is made of corrosion-resistant and easy-to-clean materials, such as stainless steel or polymer plastic, to ensure stability and durability under long-term use.

[0028] The horizontal pipe 2 is fixedly connected to the bottom end of the vertical pipe 1 to receive and collect condensed water from the vertical pipe 1. The horizontal pipe 2 is also made of corrosion-resistant material, and its design takes into account drainage efficiency and installation convenience.

[0029] The extension pipe 3 is integrally formed at the outer end of the horizontal pipe 2 and serves as a channel for the final discharge of condensed water. The extension pipe 3 can be of different lengths as required, flexibly adapting to different environments.

[0030] The vertical pipe 1, horizontal pipe 2, and extension pipe 3 are seamlessly connected, forming a highly efficient, airtight condensate drainage system. This seamless connection not only ensures smooth, unimpeded condensate transfer but also significantly reduces the risk of microbial growth caused by gaps in the joints, ensuring the hygiene and safety of the HVAC system. Furthermore, the seamless piping structure enhances the overall aesthetics and durability, providing a strong guarantee for the long-term, stable operation of the HVAC system.

[0031] See also Figure 1 、 Figure 2 、 Figure 3 , a HVAC condensate pipeline drainage anti-microbial sealed drainage equipment, a drainage device 4 is installed inside the horizontal pipe 2 and the extension pipe 3, the drainage device 4 consists of a non-return mechanism 41 and a non-powered self-weight drainage mechanism 42, the non-return mechanism 41 is installed inside the horizontal pipe 2 and the extension pipe 3, and the non-powered self-weight drainage mechanism 42 is integrally welded to one end of the bottom of the horizontal pipe 2; the non-return mechanism 41 includes a flap valve I 411 and a flap valve II 412; the non-powered self-weight drainage mechanism 42 includes an automatic drainage connecting pipe 421, a sealing cover 422, a float 423, a water inlet I 424 and a water inlet II 425; the top of the vertical pipe 1 is integrally formed with a water inlet interface 5; the outer end of the extension pipe 3 is integrally formed with a drainage interface 6.

[0032] The anti-return mechanism 41 is installed inside the transverse pipe 2 and the extension pipe 3, ensuring unidirectional condensate flow and preventing the backflow of external gas or sewage. The top of flap valve I 411 is hingedly connected to the inner top of transverse pipe 2, ensuring that flap valve I 411 can be opened and closed flexibly. The outer wall of flap valve I 411 fits tightly against the inner wall of transverse pipe 2, forming an effective sealing barrier. When condensate flows from vertical pipe 1 into transverse pipe 2, it impacts flap valve I 411, causing it to automatically open and allow condensate to pass through. When condensate stops or reverses flow, flap valve I 411 automatically closes under its own weight in conjunction with the protrusions on the bottom of transverse pipe 2, preventing the backflow of condensate. Flap valve II 412, similar to flap valve I 411, is hingedly connected to the inner top of extension pipe 3, with its outer wall fitting closely against the inner wall of extension pipe 3. This serves as a second line of defense, further enhancing the effectiveness of preventing backflow. When condensate flows through the horizontal pipe 2 to the extension pipe 3, the flap valve II 412 will also be opened by the water flow; in the case of no water flow or reverse flow, it will automatically close.

[0033] To further enhance the stability and sealing of the check mechanism 41, two protrusions are designed on the inner bottom ends of the cross tube 2 and extension tube 3. These protrusions fit tightly against the same side of flap valve I 411 and flap valve II 412, respectively. When the valves are closed, the protrusions provide additional support, helping to maintain the valves' closed position and preventing the infiltration of external air or sewage.

[0034] Flap valve I411 and flap valve II412 are installed on the same pipe loop, creating a unique dual-layer protection mechanism. This design significantly enhances the system's ability to prevent backflow. Even if one valve fails to fully close for some reason, the other valve continues to function, preventing condensate from flowing back into the system. This dual-security design reflects our high regard for HVAC system drainage safety.

[0035] The unpowered, self-weighted drainage mechanism 42 requires no external power source, relying instead on the condensate's own weight and buoyancy to achieve rapid and smooth drainage. This reduces the condensate's residence time within the pipe and mitigates the risk of microbial growth. One end of the automatic drain connection pipe 421 is integrally formed with the outer bottom end of the transverse pipe 2, ensuring a seamless connection and internal interconnection. This design not only simplifies installation but also improves the system's overall sealing performance. The automatic drain connection pipe 421 serves as the primary channel for condensate discharge, and its design takes into account smooth water flow and drainage efficiency. A sealing cover 422 is seamlessly welded to one end of the transverse pipe 2 and tightly covers the interface of the automatic drain connection pipe 421. The presence of the sealing cover 422 effectively limits the position of the float 423 and, in conjunction with it, prevents external air, dust, and microorganisms from entering the pipe system through the interface, thereby maintaining cleanliness and hygiene within the pipe. The float 423, located within the sealing cover 422, automatically controls the drainage process based on water level changes. When condensed water accumulates in the transverse pipe 2 and reaches a certain water level, the float 423 inside the sealing cover 422 floats up, thereby triggering the drainage mechanism; when the water level drops, the float 423 falls back, waiting for the next drainage cycle. Water inlet I 424 and water inlet II 425 are respectively located at the top and bottom of the sealing cover 422. Water inlet I 424 allows condensed water to flow from the transverse pipe 2 into the sealing cover 422, causing the float 423 inside the sealing cover 422 to float up due to the buoyancy generated by the condensed water. The condensed water then flows through the sealing cover 422 through the water inlet II 425 and is discharged from the automatic drainage connecting pipe 421. When the water in the transverse pipe 2 is completely drained, the float 423 inside the sealing cover 422 falls back to its original position due to the drop of condensed water, completing the purpose of automatic drainage.

[0036] Standpipe 1, the primary component for collecting and initially channeling condensate, features an integrally formed water inlet port 5 at its top. This port's design fully considers the connection requirements to the HVAC system's condensate source, ensuring smooth, leak-free flow of condensate into standpipe 1. Furthermore, it's constructed from corrosion-resistant, well-sealed materials, such as stainless steel or polymer sealing materials, to ensure long-term stability and reliability.

[0037] The extension tube 3 serves as the final channel for the condensate to drain, and its outer end is integrally formed with a drain port 6. This port is designed to facilitate connection to an external drainage pipe or container, ensuring the safe discharge of the condensate. Similar to the water inlet port 5, the drain port 6 is also made of corrosion-resistant, leak-proof materials to prevent leakage during drainage. Furthermore, the position and angle of the drain port 6 can be adjusted to suit different drainage environments and requirements.

[0038] The working principle of this HVAC condensate pipe drainage and anti-microbial sealed drainage device is as follows: When the HVAC system is operating, condensate continuously flows through vertical pipe 1 and into horizontal pipe 2. The impact of the condensate automatically opens flap valve I 411, allowing the condensate to flow through horizontal pipe 2 and into extension pipe 3, where it again opens flap valve II 412 and is discharged. The unpowered, self-weighted drainage mechanism 42 then automatically begins draining the condensate. The condensate enters the sealed housing 422 through water inlet I 424. The condensate inside the sealed housing 422 gradually rises, causing float 423 to rise under buoyancy, exposing water inlet II 425. The condensate then flows through water inlet II 425, through the sealed housing 422, and out of the system through the automatic drain connection pipe 421. As the condensate continues to drain, the water level inside the sealed housing 422 gradually drops, causing float 423 to drop back down. When the water level drops sufficiently, the drainage process automatically stops, waiting for the next accumulation and discharge of condensate.

[0039] It should be noted that the specific models and specifications of flap valve I 411, flap valve II 412, and float 423 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
