What better mixer - Single lever or dvuhventilny: features, pros and cons of devices

A wide range of goods at times makes it difficult to select the most suitable device. The buyer is often the question arises what is better to buy a mixer. After all, the model selection affects not only the appearance of the plumbing, but also ease of use, durability. Therefore, to make the right choice, you should know the basic characteristics of the models, their features, advantages and disadvantages.

Features twin valve

Despite the emergence of a modern single-lever models dvuhventilnye devices do not hand positions and remain the most popular versions of the mixers.

The main element of the design of this product is a special head parts. This element is necessary for controlling the hot and cold water streams.

On current models devices installed head parts with a rotating mechanism. The element in charge of adjustment streams made of sanitary cermet - alumina.

The design provides for two metal-ceramic plates with special holes. With technological holes made regulating water flow entering the valve.

The main feature of aluminum oxide - high strength. Due to this property, the product is resistant to the formation of various defects: chips, scratches, microcracks. This improves the reliability of the device and increases its service life.

Ceramic head parts has indisputable advantages over the product with the rubber seal. Current models are easy to open and close. old-style mixers have to "defraud" with a few extra turns of the valve. This leads to rapid wear of internal structural elements. Therefore, options with a rubber seal can not boast a long service life.

The operating principle of ceramic head parts other. It is based on the displacement of the plates from composite materials. When the water supply plates apart, thereby forming an opening through which water flows. Similarly, the water flow stops.

High-quality instrument consists of the following elements:

• a housing made of an alloy of non-ferrous metals;
• stock;
• rod lock;
• rotatable upper plate;
• Cabinet plate which is located in the lower part of the device;
• gasket to ensure a tight seal.

Despite the structural differences, both versions of two-lever mixers have both advantages and disadvantages.

Positive aspects of taps with a rubber head parts:

1. The cost of such models is lower than the option with a ceramic element.
2. rubber elements can be replaced by ceramic, if necessary. The main thing - the valve should be released by the same manufacturer as the mixer.
3. Comfortable temperature setting.
4. It does not require getting used to, because everything is done on an intuitive level.

Negative qualities are:

• short service life in comparison with the ceramic model. In addition, the rubber gasket is required to change periodically;
• to fully open the valve need to make two full turns "sheep."

Advantages of products with ceramic elements:

• long service life;
• easy to set a comfortable temperature - design of the device allows you to do this with a single valve;
• turning radius does not exceed 180 degrees - and therefore need to make fewer movements to get water comfortable temperature.

Reference. The first device, allowing to mix hot and cold water appeared in the XIX century. The inventor of the "grandparent" of modern faucets is William Thomson, better known as a theoretical physicist Lord Kelvin.

Characteristics of single-lever mixers

The main distinguishing feature of these models - the lever that performs the functions of two valves. It not only regulates the temperature, but also the intensity of the jet pressure.

In the first case, you need to move the lever to the right or to the left. In a second - up or down. To use it was convenient, manufacturers have combined these processes.

Device design is quite simple:

1. Housing. It can be made of thin metal or plastics.
2. Spout. Depending on the purpose of sanitary ware, it may be high, medium or low.
3. Switch. With it, pressure and temperature regulated water.
4. Cartridge. Is an analog of the tap-axle box to be mounted on valve model.

Single-lever model, steady demand among consumers. This is explained by a number of advantages of the product:

• attractive appearance;
• Easy to install and maintain;
• functionality and ease of use.

Do not forget about the shortcomings:

1. Demanding the water quality. They are sensitive to limescale deposits, particles of rust, a variety of impurities. Over time, they can become clogged and fail.
2. Non-repairable. perform repair work is almost impossible at home. Allowed only replacement of some elements.

Reference. To extend the life of a single-lever mixer, you need to install water filters and preventative maintenance on a regular basis.

What better mixer

Assessing the pros and cons of the models, you can come to the conclusion - the choice of the optimal variant depends on the location of the mixer installation, the overall design of the room, individual requirements. For example, in the classic interior will be more appropriate dvuhventilnye model, whereas single-lever will fit in modern design.

Both variants have advantages and disadvantages. When buying a mixer, in particular, should take into account personal preferences and do not forget about a reasonable price-performance ratio.
