Angle globe valve It's very small, but its role should not be underestimated. There are many kinds of angle valves, which are used in all areas of your home. Therefore, it is very important to select and install the angle valve. Today, the editor to share the standard installation process, at the same time remind you need to pay attention to a few points!
The full name of angle valve is "angle type" Globe valve ”It is also known as the "eight" valve. Usually, the outlet and inlet of water form a 90 degree right angle, the function and structure are basically similar, can be confused, is used to control the water pipe nozzle control valve. Because the installation of water supply system, and the installation of angle valve is relatively simple, but we should pay attention to the standard process.
Next, the editor disassembled an angle valve which has been used for many years to show its internal structure to readers.
It can be seen that the inside of the unscrewed angle valve has been polluted by a large amount of rust and scale. Obviously, the angle valve is a consumable and should be inspected and replaced regularly.
The inside of the hose connected with the angle valve is also full of dirt.
You are reminded here that many angle valve merchants say that their angle valves are made of pure copper, but they are not necessarily. Some parts of the angle valve in Mr. Sun's home are made of pure copper, but the shell and screw mouth can be made of alloy, but it can also be said to be pure copper. It can be said that the concept is changed!
How to judge whether it is pure copper? If we saw the thread mouth of several angle valves, we could find the difference between pure copper and alloy. Copper crops are copper colored, while alloy crops are silver.
Choose high-quality pure copper angle valve, at least solve two problems: 1. Rust problem, pure copper is not easy to rust; 2, fracture problem, pure copper will not become brittle as time goes by. Now many angle valve in order to ensure the sealing, the outlet hole in the angle valve is small, and there are many corners. It is easy to be blocked by sand, scale and other foreign matters in the water.
The decoration is not once and for all. Even the angle valve and hose have to be updated regularly. The kitchen hose and the corner of the water are really rusty!
First of all, it is necessary to confirm whether the angle valve installed is a toilet or a lavatory basin. Many angle valves are used at home, including direct ones and flat angle ones. They are usually installed after being glued with anti-skid glue through the turnbuckles, so as to prevent water leakage.
For example, the water inlet angle valve is usually installed on the wall 200 mm above the ground at the side of the toilet. For this kind of high back toilet, the angle valve is installed on the back of the toilet and blocked by the toilet after installation.
In order to facilitate maintenance, the angle valve manufacturer considers these reasons in production, and generally has a repair hole at the bottom of the toilet. During maintenance, the water inlet angle valve can be opened from the maintenance hole, or the water tank cover can be opened from the upper part of the water tank for maintenance, or the whole set of products can be removed for maintenance.
Before installation, check whether there are sand particles and sundries at the water pipe connection, so as to prevent the ceramic chip from jamming and water leakage. When wrapping the raw material tape at the joint of the water pipe and the angle valve, attention should be paid to the winding thickness, which is usually 3-5 turns to prevent aging and water leakage.
Secondly, professional bathroom installers should be invited to do door-to-door installation, and they should be installed in a place with good water quality to avoid accidental loss. Some bathroom appliances should not be wrapped with excessive raw material belt, such as the two ends of shower hose and the place where the silk hose is connected. The more the wound is, the more serious the water leakage will be. 1 ~ 2 layers are appropriate.
When installing, do not hold the hand wheel of the angle valve to rotate and fasten. Wrap several layers of cloth or paper towel on the valve body, and then clamp the valve body with a wrench to rotate and fasten. If the buffer is not wrapped directly on the valve body, it may scratch the surface of the angle valve and affect the appearance.
After installation, the main valve should be opened for water inflow, and the corner valve should be detected for leakage. Generally, the inlet water can be pressurized for about 15 minutes before confirmation. If the angle valve is not installed on the water pipe, the angle valve should be closed. The leakage test should be careful in case there is no leakage at that time, and the leakage test should be observed several times.
The main function of angle valve is to control the flow and size of water device, and the angle valve is generally installed in the water supply system, angle valve is generally common in our kitchen and toilet. In some baths and the top of the toilet is also the installation of angle valve, the above is the installation steps of angle valve, you can refer to Oh!
