Introduction to various types of nozzles in hardware

Water faucet, also known as faucet, is a kind of valve-type device that is usually used on the water pipe. With the continuous improvement of people's life production and living standards, the water spout product has a world of difference in function and appearance compared with before, and various professional functions and various novel style products have emerged. Taps are mainly the following:

Elbow touch water nozzle: also known as elbow touch faucet. Use elbows to touch long handles to turn the water on and off. Hands do not come into contact with the spout and do not cause cross-infection. Some have a pneumatic stabilizer at the water outlet, and the water flow is in an inflatable foam, soft and stable. For ** diagnosis and treatment rooms, laboratory dedicated. There are two kinds of single and double. Single-connected tap water, double-connected with cold and hot water. Elbow touch nozzles are made of brass, the surface of chrome, abrasion resistance and easy to clean. Nominal pressure is 0.6MPa and the use temperature is less than 100°C.

Hot water mouth: also known as hot water tap. Installed in hot water pipes, boiling water boilers, electric water boilers, tea buckets, warm buckets, used to put water. The structure is a cock type, that is, the valve body and the valve body are directly contacted and sealed with a taper of 1:7, and the water flow is opened and closed by the rotation of the valve core. Made of brass, surface polished or chrome plated. Nominal pressure is 0.15MPa, nominal diameter is 15 to 25mm, and the use temperature is less than 100°C.

Basin tap: also known as basin faucet. Mounted on ceramic washbasins for open cold or hot water. The structure is generally a screw lift type, that is, the rotation of the handle causes the screw to move up and down to release water or shut off. Made of brass and chrome-plated. Valve body shape and handle are various in form and decorative. The nominal pressure is 0.6MPa, the nominal diameter is 15mm, and the use temperature is less than 100°C. Some lavatory faucets are also equipped with a drip-lift rod, which can be directly lifted to open the faucet's water outlet, eliminating sewage.

Bath spout: also known as bath faucet. Installed on the upper side of the bathtub for opening hot and cold mixed water. Can be connected to cold, hot two pipes called dual-type; in addition to cold, hot two pipes, but also attached to the valve body shower shower device called triple. The structure of the open and close water flow is generally a screw lift type, and the temperature of the mixed water is controlled by rotating the double handle to adjust the flow of cold and hot water, respectively. In recent years, the structure of handle temperature control and temperature control has been developed. The single-handle thermostatic bathtub faucet that appeared in the 1980s can be used for temperature control and constant temperature control with a single handle, which is more convenient to use and more compact in structure. Bathtub faucets are made of brass and have a chrome finish. The molding requirements are in harmony with other bathroom accessories.

Cold spout: also known as the tap. Installed on the tap water line for water discharge. According to the valve body material can be divided into copper spout, malleable iron faucet and cast iron spout, the latter two are widely used. Nominal diameter is generally 15mm, 20mm, and 25mm, nominal pressure is 0.6MPa to take over the nozzle: also known as the belt tap. The function and structure are the same as those of a cold water nozzle, and the outlet is equipped with a detachable nut connector, which can be connected to a rubber tube or a plastic tube. The body material is brass, malleable cast iron and gray cast iron.

Laboratory nozzle: also known as laboratory leader. The function and structure are the same as those of the copper refrigerating nozzle, but the outlet is long tapered and has a non-slip groove, which is easy to insert the rubber tube or the plastic tube. The water is stable and there is no sputtering. It is mostly used by laboratories and laboratories. The exterior is chrome-plated.

Foot pedal: also known as foot faucet. It consists of base, valve body, pedal, and outlet pipe. The opening and closing of the water flow is achieved by pedal pedals. For inconvenience or can not be switched by hand, such as **, public canteens and so on. The valve body is made of brass or gray cast iron, the treadle is malleable cast iron, and the outlet pipe is brass.
