Toilet Tank Accessories

The toilet tank accessories are the core part of the toilet, which is called the "toilet heart" in the industry. It is mainly composed of an inlet valve, a drain valve, and a button. Roughly speaking, it can be divided into two categories: conjoined and split.

One-piece fittings are used for one-piece toilets. Split fittings are used for split toilets. The inlet valve part can be divided into side inlet and bottom inlet, and there is also a rear inlet. The drain valve part can be divided into double-press type, hanging chain type, and barrel type. The button part can be divided into side buttons, top buttons, and front buttons.

Overview of the inlet valve

The water inlet valve is a device used to automatically control the water inlet of the water tank. When the water level in the water tank drops to the working water level, the water inlet will automatically start, and the water inlet will automatically stop when the water level reaches the working water level.

Overview of the drain valve

The drain valve is used to control the drain device of the water tank. After it is opened, it can discharge a preset amount of water and can be automatically closed.

Folding edit this paragraph quality identification skills

1. Look at the certification marks and certificates: many water tank accessories have not passed the Chinese water-saving certification. If the accessories have the US UPC certification, it means that their products can be sold in the US market. This is an objective criterion for reference, please remember!

2. Look at the weight and weight in the hand. If it feels heavy, it means that it is real.

3. Smell: to see if there is a pungent smell, if not, it is a reliable quality.

4. Press: Press the drain valve easily with your hand. Does it feel easy? Easiness is a good product.

5. Look at the color of the product. The plastic of the inlet valve must be translucent. If it is a particular color or opaque, the material is shrinking and stealing.

6. Look at the smoothness of the product surface, whether the mold is finely named whether there are flashes, burrs, etc., if not, it is OK. 20080222072632793.jpg

Folding the critical water level

The lowest water level of the inlet valve when the siphon is generated and when the siphon is terminated. Abbreviated as: CL

Folding remaining water level

Close the water inlet valve at the working water level and open the drain valve. When the drain valve is naturally closed, the height of the water level in the water tank. Abbreviated as: RL

Folding water hammer
