What Are the Fauces?

The faucet is a common name for a water valve. It is used to control the size of the water flow. It has the effect of saving water. The faucet is updated very quickly, from the old-fashioned cast iron process to the electroplated knob type, and then to the stainless steel single temperature and single control faucet, stainless steel dual temperature and double control faucet, and kitchen semi-automatic faucet. Nowadays, more and more consumers choose faucets from a comprehensive consideration from many aspects such as material, function and shape.

1. According to the material, it can be divided into SUS304 stainless steel,

Production process of faucet:

Copper ingots dissolve casting (low-grade sand casting, gravity casting of high-quality faucets) post-cleaning casting inspection machining tolerance inspection test leakage grinding surface inspection plating plating inspection assembly Testing water and leaking finished product inspection packaging delivery.

Casting: Low-grade casting with cast sand, high-quality faucet casting with gravity, the relatively new technology is die-casting, one-time grinding molding is similar to the zinc alloy die-casting process.

Quality control: The quality in the production process before the finished product is controlled by the quality control, and the final product to the packaging are sampled by the quality assurance part, mainly to check the packaging and placement of the product.

Look at the brightness

The surface chrome plating process of a good faucet is very particular about it, and it usually takes several steps to complete. The quality of a faucet depends on its brightness. The smoother and brighter the surface, the better the quality.

Turn handle

When a good faucet turns the handle, there is no excessive gap between the faucet and the switch, and it is easy to open and close without slipping. But poor quality faucets not only have a large gap, but also a large sense of obstruction.

Listen to the sound

The material of the faucet is the hardest to distinguish. The good faucet is cast as a whole, and it sounds dull when beaten. If the sound is very brittle, it must be of low-grade stainless steel, which contains more iron elements, and the quality will be a grade worse.

Recognition mark

If you ca nt tell the difference, you can choose a more regular brand. Generally regular products have the brand logo of the manufacturer, and some non-formal products or some inferior products often stick only some paper labels, even without any marks. Be careful when buying.

1. Various impurities in the pipeline should be completely removed during installation. Prevents spool damage, jams, blockages, and leaks. At the same time, the surface should be cleaned so that no building material residues remain.

2. There is no need to use excessive force when switching on or off any kind of faucet products, just twist or dial gently. Even a traditional faucet doesn't need a lot of effort to screw it. In particular, do not use the handle as an armrest to support or use it. Products with a screen cover at the water outlet should be removed and washed to remove impurities after a period of use. For products with hoses, care should be taken to keep the hoses naturally stretched to avoid breaking.

3. The metal hose of the shower head of the bathtub faucet should be kept in a natural stretched state. Do not coil it around the faucet when not in use. At the same time, when using or not in use, pay attention not to form a dead angle at the joint between the hose and the valve body, so as not to break or damage the hose.

4. After a short period of use, the phenomenon of incomplete closure, leakage, loose handles, loose connection and leakage of water nozzles sometimes occurs. Generally, consumers can solve it by themselves.

5. Precautions for faucet cleaning:

(1) Do not wipe the surface of the faucet with a hard object such as a steel ball, because the steel ball is very hard and it is easy to scratch the surface of the faucet.

(2) It is best to use a neutral detergent for cleaning. Strong acid and alkaline cleaners are not suitable for cleaning with a water tap.

(3) After the faucet is cleaned, the remaining water on the surface should be dried with a dry lint-free towel (the same is true for glass cleaning), so as not to cause scale.

In normal life, sometimes I find that the faucet still drips after being tightened, and it keeps dripping from the faucet outlet or the joint, which not only causes a lot of waste, but sometimes its sound will cause some trouble. In fact, the structure of the faucet is very simple. The maintenance of the leak can be repaired by yourself. Generally speaking, if the leak of the faucet is replaced by the gasket parts such as the axial gasket or the triangular seal, has been solved. However, you must turn off the main faucet switch at home before renovating.

Faucet

Regarding the repair of water leakage at the faucet joint, the reason for the water leakage is nothing more than the damage of the water-proof tape that is used to tie the faucet part (fixing screw). Therefore, just use a wrench to remove the faucet, and re-roll a new waterproof tape in the place where the screw is fixed. The following are the maintenance steps: First, fasten the faucet first, and use the wrench to counterclockwise Remove by turning. Second, roll the threaded hole outwards, and wind up the threaded part with windscreen tape 5-6 times.

Check whether the faucet has been adjusted in the clockwise direction with the water bolt wrench. After the final installation is completed, open the main switch and try to confirm whether there will still be water leakage.

Even if the faucet is fastened, there will still be water leakage:

1. The cause of water leakage at the water outlet: it is caused by the wear of the shaft gasket in the faucet. Use pliers to loosen and remove the gland bolt, take out the shaft washer with a clip, and replace it with a new shaft washer.

2. Leakage of the gap in the lower part of the faucet: it is caused by the wear of the triangular seal in the gland. You can loosen the screw to remove the bolt head, then loosen the gland, and then take out the triangular seal on the inside of the gland and replace it with a new one.

3 Water leakage at the joint of the pipe: Generally, the cap nut is loose. At this time, you can re-tighten the cap nut or replace it with a new U-shaped gasket.

If there is less water in the faucet, it may be a leak. Because the water stop disk of the single-handle faucet is stuck with sand and gravel, this phenomenon is still to be disassembled by a professional maintenance engineer. However, if the rubber pad is damaged, it must be replaced. Generally speaking, the correct use of the faucet means that the faucet is not rotated too tightly, so that the faucet rubber pad can maintain the life of 7 or 8 years, but the faucet in the hot water part is liable to reduce its life due to thermal expansion and contraction Therefore, it is generally recommended that the hot and cold rubber pads be replaced regularly at the same time.
