What parts does the mixer consist of?

The mixer is an indispensable element of any living space. When closed, it holds liquid. When open, it mixes cold and hot water and allows you to regulate the intensity of the jet pressure.

However, a wide range can cause a real headache. After all, in order to choose a suitable model, it is necessary to take into account not only the appearance of the device, but also the reliability of the design. This is why it is so important to know the mixer configuration. If necessary, the knowledge gained will help determine the degree of complexity of the repair - whether you can do it yourself or will have to use the services of professionals.

Design of a two-valve kitchen faucet

Two-valve models are considered a classic version of a plumbing device. Despite the fact that the products are already obsolete, they are in stable demand among consumers. This is influenced by the low cost of plumbing fixtures, as well as the ability to use them in retro-style interiors.

The operating principle of such devices is to control the water flow and temperature of the liquid using two “wings”, each of which is connected to a pipe with the corresponding temperature.

The design of two-valve models consists of the following elements:

• crane axle box;
• "lamb";
• housings;
• aerator;
• spout

The product body is installed in a specially designated place in the kitchen sink.To ensure a tight, airtight connection, a rubber seal is placed at the junction of the plumbing fixtures and the sink.

Based on the type of “controls”, household two-valve models are divided into two types:

• with ceramic discs that rotate relative to each other within a strictly limited radius;
• with valve heads that perform reciprocating movements.

The convenience and ease of use of the mixer, as well as its service life, depend on the design of the faucet axle.

Modern models of plumbing fixtures are equipped with faucet axle boxes with ceramic elements. They are more reliable and durable. The head of such a product supplies or shuts off water depending on the position of small holes on the ceramic plates. When two planes are connected, liquid flows out.

The larger the contact area of ​​the plates, the more intense the water pressure. When the wings are turned so that the holes no longer line up, the flow is blocked.

The design of the ceramic crane axlebox includes:

• stock;
• two aluminum oxide plates;
• turn signal;
• rubber gasket;
• frame;
• fixing device.

The rod is installed in the mixer body, made of brass. If the installation is carried out correctly, you will hear a characteristic sound. Next, the valve is screwed onto the stem. To provide torque from the valve to the ceramic plates, a special turner is used.

To create a tight seal, a sealing gasket made of soft plastic or thick rubber is installed between the rod and the body. If it is damaged, water begins to leak from under the base of the mixer.

Reference. Correct and reliable fixation of the sealing gasket is the key to long-term and comfortable use of the mixer.

What does a single lever kitchen faucet consist of?

Single-lever models are more stylish, modern and easy to use.

The advantages of such models are:

1. Easy to use. You can adjust the temperature and water pressure with one hand.
2. Economical. The design of the device allows you to quickly adjust the temperature and intensity of the jet. This allows you to significantly reduce water consumption.

Single lever models consist of elements:

• aerator;
• housings;
• a switch made in the form of a lever;
• "spout";
• cartridge.

To adjust the water temperature, the lever is rotated horizontally. The intensity of the pressure is adjusted by moving the lever in the vertical plane.

The aerator, which is installed on most models, makes use more convenient - the device prevents splashing and reduces noise levels. In addition, the device helps reduce water consumption.

The main element of the single-lever version is the cartridge. It can be of two types:

1. Ball. It is based on a hollow sphere in which three small holes are located. Cold and hot water flows through two of them. Third - to output water at the required temperature. The structure is connected directly to the handle, which changes the position of the sphere.
2. Disk. Its principle is similar to the operation of a crane axle box. The device consists of two disks made of metal ceramics. One of the planes is movable and moves together with a lever. Each disk has a hole. When they coincide, water enters the system.If not, the flow is blocked.

Models with ceramic cartridges are the most common.

How does an automatic mixer work?

The operating principle of single-lever and double-valve faucets is based solely on physics. More modern models work electronically.

The design of contactless models is much more complex than conventional ones. It includes:

• frame;
• thermostat;
• solenoid equipped with a lock;
• sealing material;
• core;
• screening device in the form of a coil;
• membrane installed at the end of the core;
• infrared sensor.

The infrared sensor reacts to movement. When triggered, voltage begins to flow to the solenoid. The shielding coil drives the core, raising it. It is drawn into the cavity of the solenoid, lifting the membrane, and water begins to flow into the tap.

When the power stops flowing, the reverse process starts: the core returns to its original position, the membrane drops.

Such a device requires a constant power supply. To do this, you can use an electrical network, a battery or batteries.

Features of a bathroom faucet with shower

The faucet is an essential element of the bathroom. When choosing a suitable model, you should pay attention not only to the appearance of the product, but also to its design. Bath faucets come in two types:

1. Two-valve. It includes two valves with which the temperature and intensity of water pressure are regulated.
2. Single lever. The lever of such a device operates in two planes - vertical and horizontal. When you raise the handle, the water pressure changes, and when you turn it, the temperature changes.

However, unlike kitchen models, the design of bathtub faucets includes a hose and a shower with a shower head, which is fixed to the wall.

A variety of faucet models allow you to choose a model that will meet all individual preferences. Knowing the design of the product will not only make the choice easier, but will also allow you to repair the device if necessary.
