Introduction of various types of nozzles and functional features in plumbing hardware

The faucet is also called a faucet. One type of plumbing hardware is a valve type device that is usually used on a water pipe. With the continuous improvement of people's life, production and living standards, the faucet products have a world of difference in function and appearance compared with the past, and various professional functions and various novel style products have emerged. There are mainly the following types of water nozzles:

Elbow touch faucet: also known as the elbow touch faucet. Use the elbow to touch the long handle to open and close the water flow. Hands do not touch the faucet and do not cause cross-contamination. Some are equipped with an aeration stabilizer at the water outlet, and the water flow is inflated foam, soft and stable. It is used for hospital diagnosis and treatment rooms and laboratories. There are two types of single and double. Single-connected tap water, double-connected can be connected to cold and hot water at the same time. The elbows are made of brass and are chrome-plated, abrasion resistant and easy to clean. The nominal pressure is 0.6 MPa and the service temperature is less than 100 °C.

Hot water nozzle: also known as hot water tap. It is installed on hot water pipes, boiling water boilers, electric water heaters, tea buckets and warm water buckets for water release. The structure is a cock type, that is, the valve core and the valve body are directly contacted and sealed with a 1:7 taper, and the water flow is opened and closed by the rotation of the valve core. Made of brass, polished or chrome-plated. The nominal pressure is 0.15 MPa, the nominal diameter is 15 to 25 mm, and the service temperature is less than 100 °C.

Basin faucet: also known as basin faucet. Installed on a ceramic washer for opening cold or hot water. The structure is generally a screw lifting type, that is, the rotation of the handle causes the screw to be lifted and lowered to release water or close. Made of brass and chrome-plated. The valve body shape and handle are various in form and decorative. The nominal pressure is 0.6 MPa, the nominal diameter is 15 mm, and the service temperature is less than 100 °C. Some basin faucets are also equipped with a falling water lifting rod, which can be directly pulled to open the water outlet of the face washer to remove the sewage.

Bathtub faucet: Also known as bathtub faucet. Installed on the side of the bathtub for open hot and cold water. The two pipes that can be connected to cold and hot are called double-connected; in addition to the two pipes, cold and hot, the shower head device is also connected to the valve body. 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 rates of the cold and hot water by rotating the double handles respectively. In recent years, the structural form of handle temperature adjustment and constant temperature control has been developed. The single-handle thermostatic bathtub faucet that appeared in the 1980s can be temperature-controlled and thermostatically controlled with a single handle, which is more convenient to use and more compact. The bathtub faucet is made of brass, and the exterior is chrome-plated. The styling requirements are in harmony with other accessories in the bathroom.

Cold water nozzle: also known as tap water tap. Installed on the water pipe, used to release water. According to the valve body material, it can be divided into three types: copper faucet, wrought 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. The nozzle is also called the belt faucet. The function and structure are the same as those of the cold water nozzle. The water outlet is equipped with a detachable nut joint, which can be connected with a rubber tube or a plastic tube. The body material is brass, malleable iron and grey cast iron.

Test faucet: also known as the test faucet. The function and structure are the same as those of the copper cooling nozzle, but the water outlet is long tapered and has a non-slip groove for easy insertion of rubber or plastic tubes. The effluent is stable and has no sputtering. It is mostly used in laboratories and laboratories. The exterior is chrome plated.

Foot faucet: also known as the foot faucet. It consists of a base, a valve body, a pedal, and an outlet pipe. The opening and closing water flow action is realized by the foot pedal. For occasions that are inconvenient or impossible to switch by hand, such as hospitals, public canteens, etc. The valve body is made of brass or grey cast iron, the pedals are malleable cast iron and the outlet pipe is brass.
