Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipes and pipe fittings, and in particular to an H-shaped pipe with a swirl guide structure. Background Art
[0002] In building drainage systems, one of the common drainage methods is the H-shaped pipe drainage method, that is, one vertical pipe for drainage and one vertical pipe for exhaust. The drain pipe and the exhaust pipe are connected by a vent pipe to adjust the positive and negative air pressure in the drain pipe to ensure the effective drainage capacity of the drain pipe. However, water can easily enter the exhaust pipe during the drainage process, affecting the exhaust effect. Although some H-shaped pipes with anti-backflow effects have appeared on the market, they mainly achieve the purpose of reducing water flow into the exhaust pipe by setting a water retaining part near the intersection of the drain pipe and the vent pipe or inside the vent pipe. However, this design has certain problems, specifically:
[0003] First, the setting of the water retaining part reduces the area of the vent pipe, thereby affecting the exhaust effect; second, the water retaining part can only block the water flow from entering the vent pipe, but cannot play the role of water vapor diversion, which may cause water flow turbulence and poor drainage; finally, the design and mold molding of the water retaining part are difficult to implement and the cost is relatively high. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0044] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.
[0045] It should be noted that similar numbers and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined or explained in subsequent figures. In addition, all directional indications in this application (such as up, down, left, right, front, back, bottom...) are only used to explain the relative position relationship, movement, etc. between the components under a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the descriptions of "first", "second", etc. in the application are for descriptive purposes only and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.
[0046] like Figure 1-7 As shown, this embodiment provides an H-shaped pipe with a swirl guide structure, including a drain pipe 1, an exhaust pipe 2, and a vent pipe 3. The drain pipe 1 and exhaust pipe 2 are arranged in parallel, with the longitudinal axes of the two pipes parallel. The vent pipe 3 is connected to the drain pipe 1 at one end and to the exhaust pipe 2 at the other end. The vent pipe 3 is arranged at an angle and is in the shape of a straight pipe. A first connection port 4 is provided at the location where the drain pipe 1 and the vent pipe 3 connect, and a second connection port 5 is provided at the location where the exhaust pipe 2 and the vent pipe 3 connect. The lowest point of the first connection port 4 is lower than the lowest point of the second connection port 5. A raised swirl guide structure 6 is provided on the inner wall of the drain pipe 1. The swirl guide structure 6 has an arc-shaped cross-section and is arranged in a spiral along the inner wall of the drain pipe 1, avoiding the first connection port 4. The drain pipe 1, exhaust pipe 2, and vent pipe 3 are an integrally formed structure. The H-shaped pipe with the swirl guide structure is manufactured using a blow molding process.
[0047] In this embodiment, when water flows downward through the drain pipe 1 and contacts the raised swirl guide structure 6, it is blocked, preventing backflow. At the same time, the water flows along the surface of the swirl guide structure 6, preventing backflow while allowing the water to rotate downward under the action of the spirally arranged swirl guide structure 6, forming a swirl acceleration and improving water vapor diversion. Because the swirl guide structure 6 is arranged away from the first connection port 4, the water flows along the surface of the swirl guide structure 6 without passing through the first connection port 4, further preventing the water from splashing into the vent pipe 3. The H-shaped pipe with the swirl guide structure can be manufactured as a whole using a blow molding process, which is low in cost, high in material utilization, and has good sealing performance. This can improve the drainage function of the H-shaped pipe with the swirl guide structure and avoid the risk of leakage.
[0048] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the scope of the technical concept of this utility model.
