直通堵头 (Zhítōng Dǔtóu) - Through-Flow Drain Plug
直通堵头, commonly referred to as through-flow drain plugs, are plumbing components designed to allow water drainage while simultaneously enabling the passage of objects or facilitating cleaning. They are frequently utilized in situations where complete blockage of a drain is undesirable or impractical.
Material:
- Plastic (PVC, PP): Lightweight, corrosion-resistant, and cost-effective. Suitable for general household use.
- Stainless Steel: Durable, resistant to corrosion and high temperatures. Often used in commercial kitchens and environments requiring frequent cleaning.
- Brass: Offers good corrosion resistance and a robust build. Commonly found in older plumbing systems.
Purpose:
The primary purpose of a 直通堵头 is to provide a temporary or semi-permanent opening in a drain line for:
- Object Retrieval: Allowing the recovery of dropped items (e.g., jewelry, small toys) without dismantling the plumbing.
- Drain Cleaning: Facilitating the passage of drain snakes or cleaning rods to remove obstructions.
- Temporary Drainage: Providing a controlled outflow during plumbing repairs or maintenance.
- Water Sampling: Enabling the collection of water samples from a specific drain point.
Function:
A typical 直通堵头 features a threaded body that screws into the drain opening. It incorporates a central passageway that permits the flow of water and the passage of objects. The plug's design ensures a relatively tight seal when not in use, preventing leaks. Some models include a handle or cap for easy removal and installation.
Usage Scenarios:
- Bathroom Sinks & Tubs: Retrieving dropped items or cleaning hair clogs.
- Kitchen Sinks: Recovering utensils or cleaning food debris.
- Washing Machines: Clearing lint or small objects from drain lines.
- Floor Drains: Facilitating cleaning and maintenance.
- Commercial Kitchens: Cleaning grease traps and removing food waste.
Common Types:
- Straight Through-Flow: The simplest design, featuring a straight passageway.
- Angled Through-Flow: Incorporates an angled passageway for easier access or to accommodate specific plumbing configurations.
- Removable Handle Type: Features a handle for convenient removal and installation.
- Cap Type: Utilizes a cap to seal the passageway when not in use.
- Adjustable Type: Allows for varying degrees of flow control.
- Rubber/Silicone Sealed Type: Provides a tighter seal to prevent leaks and odors.
