In home renovations, the corner valve is one of the few things that are most easily overlooked. If you accidentally purchase a poor-quality angle valve, it can cause thousands of losses. Angle valve installation should be specially requested by professionals to install, the following small series briefly introduces the precautions of the lower angle valve installation.
First, raw material and hemp, and liquid raw material
All three can be used for thread sealing. When used in large quantities, wrapping and lead oil are more economical. Household raw tape is more convenient. The newer liquid raw material tape is actually an anaerobic adhesive, coated on the threads. Leakproof, the disadvantage is that it takes a few hours to one day to test the water, the advantage is that there is no need to tighten tightly, it will not leak (this is more convenient on large-diameter threads).
Second, when it is necessary to wrap raw tape,
When the raw material can not be wrapped around the thread sealed place needs to be wrapped around the raw material band, the place sealed by the rubber pad can not be wrapped around the raw material band, but it is easy to leak. The common thread seals are: the angle valve is connected to the wall, the water nozzle is connected to the wall, the wire (including the mixed faucet's curved foot wire) is connected to the wall, and the three-way thread is connected; the common seal is not The places where raw tapes need to be wrapped are: hose angle valve, pair of wire connection hoses, curved foot-to-silk mixing faucets, shower hoses, mixing faucets and nozzles, and various rubber-bonded pads. Connections.
Third, the correct winding method:
1 Remove foreign material from the connection site and keep it clean.
2 Note the direction of winding. Take the angle valve as an example. When the angle valve is screwed into the thread in the wall, the angle valve rotates clockwise to the right. Then we wrap the leftover tape around the corner valve in the counterclockwise direction to the left. When tightening the angle valve, the tightening will be tightened and it will not come loose.
3 When wrapping, tighten the raw material tape so that the raw material tape is tightly attached to the thread. Tighten it tightly. Do not wrap it loose. Use a hand to press the ring and press it tightly.
4 As for winding “layersâ€, there are no rigid regulations, which can be tightened tightly and not leaking, but according to experience, it is usually necessary to wind more than ten turns to ensure the sealing effect.
5 When screwing, don't screw it to death. It doesn't have to be twisted and screwed. It doesn't leak when it's screwed on. In addition, attention should be paid to the depth of screwing in. For example, the two curved legs of the hot and cold water mixing valve should be careful to keep the distance from the wall, especially when the depths of the two internal wire elbows in the wall are inconsistent. under,
By the way, the angle valve does not necessarily have to be turned upwards, depending on the actual situation, such as the length of the hose, pointing to the direction in which the hose can naturally bend. For example, if the hose is longer, the angle valve outlet can be inclined Next, let the hose hang down naturally to avoid accidental stress caused by the hose.
The relevant information about the installation of the angle valve is introduced here for everyone. I hope this article will help you. If you still have anything you don’t understand, you can follow our website and we’ll get back to you as soon as possible.
