Faucet type of piping hardware

Faucets are also called faucets. The main component is the valve body. There are eight main types of water nozzles:

1. cold water faucet: also known as tap water faucet. Installed on the tap water pipeline for drainage. According to the material of the valve body, it can be divided into three types: copper nozzle, malleable cast iron nozzle and cast iron nozzle, and the latter two types are widely used. The nominal diameters are generally15mm, 20mm and 25mm, and the nominal pressure is 0.6mpa..

2. Take over the water nozzle: also known as the faucet. The function and structure are the same as the cold water nozzle, and the water outlet is equipped with a detachable nut nozzle, which can be connected with rubber pipes or plastic pipes. The valve body is made of brass, malleable cast iron and gray cast iron.

3. Laboratory faucet: also known as laboratory faucet. The function and structure are the same as those of copper cooling water nozzle, but the water outlet is long cone-shaped and has anti-slip groove, which is convenient for inserting rubber or plastic pipes. Stable effluent, no sputtering, mainly used in laboratory. All appearances are chrome plated.

4. Pedal: Also called pedal. Consists of a base, a valve body, a pedal and a water outlet pipe. The action of switching water flow is realized by pedal. Used in places where it is inconvenient or impossible to switch by hand, such as hospitals and public canteens. The valve body is made of brass or gray cast iron, the pedal is made of malleable cast iron and the outlet pipe is made of brass.

5. Elbow touching the faucet: also known as elbow touching the faucet. Touch the long handle with your elbow to turn the water flow on and off. Hands don't touch the water nozzle, which won't cause cross infection. Some are equipped with inflatable flow stabilizers at the outlet, and the water flow is inflatable foam, which is soft and stable. For the hospital clinic, laboratory dedicated. There are two kinds: single and double. Single tap water connection, double tap water connection can simultaneously connect hot and cold water. Elbow nozzles are all made of brass with chrome-plated surface, which is wear-resistant and easy to clean. The nominal pressure is 0.6MPa and the service temperature is less than 100℃.

6. Hot water faucet: also known as hot water faucet. It is installed on hot water pipes, boiling water boilers, electric boiling water boilers, tea buckets and warm water buckets for drainage. The structure is cock-type, that is, the valve core is in direct contact with the valve body, and the taper is 1:7. The water flow is turned on and off by the rotation of the valve core. They are all made of brass, and their surfaces are polished or chrome plated. The nominal pressure is 0. 15MPa, the nominal diameter is 15 ~ 25 mm, and the service temperature is less than 100℃.

7. washbasin faucet: also known as washbasin faucet. Installed on a ceramic washbasin for opening cold water or hot water. The structure is generally spiral lifting type, that is, through the rotation of the handle, the screw is lifted and lowered to release water or turn off water. Made of brass and chrome plating. The valve body has various shapes and handle forms, which is very decorative. The nominal pressure is 0.6MPa, the nominal diameter is 15mm, and the service temperature is less than 100℃. Some washbasin faucets are also equipped with a drop lever, which can be directly pulled to open the sink of the washbasin and discharge sewage.

8. Bathtub faucet: also known as bathtub faucet. Installed above one side of the bathtub, used to turn on hot and cold water. Those that can connect hot and cold pipes are called duplex; In addition to the hot and cold water pipes, there is also a shower nozzle device connected to the valve body, which is called triple type. The structure of opening and closing water flow is generally spiral lifting type, and the temperature of mixed water is controlled by adjusting the flow of cold water and hot water respectively by rotating double handles. In recent years, the structural forms of handle temperature control and constant temperature control have been developed. The single-handle faucet of temperature-regulating bathtub appeared in 1980s, which can be used for temperature regulation and constant temperature control with a single handle. More convenient to use and more compact in structure. Bathtub faucets are mostly made of brass, and the appearance is chrome-plated, and the modeling requirements should be coordinated with other bathroom accessories.
