Introduction to the types and functional characteristics of various faucets in plumbing hardware

Faucet is also called faucet, a kind of plumbing hardware, which is a valve type device usually used on water pipes. With the continuous improvement of people's life, production and living standards, faucet products have been very different in function and appearance from before, and products with various professional functions and novel styles have appeared. There are mainly the following types of faucets:

Elbow touch faucet: also known as elbow touch faucet. Touch the long handle with your elbow to open and close the water flow. Do not touch the faucet with your hands and will not cause cross-infection. Some are equipped with an inflatable flow stabilizer at the water outlet, and the water flow is in the shape of an inflatable foam, which is soft and stable. It is dedicated to the diagnosis and treatment rooms and laboratories of hospitals. There are two types: single and double. Single connection can be connected to tap water, dual connection can be connected to cold and hot water at the same time. The elbow taps are all made of brass, and the surface is chrome-plated, wear-resistant and easy to clean. The nominal pressure is 0.6MPa, and the operating temperature is less than 100°C.

Hot water nozzle: also known as hot water tap. Installed on hot water pipes, boiling water boilers, electric boiling water boilers, tea buckets, and warm water buckets for water discharge. The structure is a plug type, that is, the valve core and the valve body directly contact and seal with a 1:7 taper, and the water flow is opened and closed by the rotation of the valve core. They are all made of brass, and the surface is polished or chrome plated. The nominal pressure is 0.15MPa, the nominal diameter is 15-25mm, and the operating temperature is less than 100°C.

Bath basin faucet: also known as basin faucet. Installed on the ceramic lavatory, used to open cold or hot water. The structure is generally screw lift type, that is, the screw is lifted up and down to discharge or close by the rotation of the handle. Made of brass, chrome-plated on the outside. The valve body has various shapes and handles, which are highly decorative. The nominal pressure is 0.6MPa, the nominal diameter is 15mm, and the operating temperature is less than 100°C. Some basin faucets are also equipped with a drain lever, which can be directly lifted to open the drain of the washing machine to drain sewage.

Bathtub faucet: also known as bathtub faucet. Installed above one side of the bathtub, used to open hot and cold mixed water. The one that can be connected to the cold and hot pipes is called the double type; in addition to the cold and the hot pipes, the shower nozzle device is also connected to the valve body is called the triple type. The structure of the opening and closing water flow is generally a spiral lifting type, and the temperature of the mixed water is controlled by adjusting the flow of cold and hot water by rotating the double handle. In recent years, the structure of handle temperature adjustment and constant temperature control has been developed. The single-handle thermostatic bathtub faucet that appeared in the 1980s can be used for temperature adjustment and constant temperature control with a single handle, which is more convenient to use and has a more compact structure. The bathtub faucet is mostly made of brass, and the surface is chrome-plated. The shape requirements are coordinated with other bathroom accessories.

Leng Faucet: Also known as the tap. Installed on the tap water pipeline for water discharge. According to the valve body material, it can be divided into three types: copper faucet, malleable iron faucet and cast iron faucet. The latter two are widely used. The nominal diameter is generally 15mm, 20mm, and 25mm, and the nominal pressure is 0.6MPa

Take over the faucet: also known as the belt faucet. The function and structure are the same as the cold water nozzle, and the water outlet is equipped with a removable nut to take over, which can be connected to a rubber tube or a plastic tube. The valve body material adopts brass, malleable cast iron and gray cast iron.

Laboratory faucet: also known as the laboratory leader. The function and structure are the same as the copper refrigeration faucet, but the water outlet is long and tapered and has a non-slip groove, which is convenient for inserting rubber or plastic pipes. The effluent is stable and there is no spattering, and it is mostly used in laboratories and laboratories. The exterior is chrome plated.

Foot faucet: also known as foot faucet. It is composed of a base, a valve body, a pedal, and a water outlet pipe. The opening and closing of the water flow is realized by pedaling. It is used in situations where it is inconvenient or cannot be opened and closed by hand, such as hospitals, public canteens, etc. The valve body is made of brass or gray cast iron, the pedal is made of malleable cast iron, and the water outlet pipe is made of brass.
