A mixer tap is a sanitary appliance that allows you to control the water flow and obtain water of the required temperature when mixing hot and cold water.
Mixer parts:
Water supply control mechanism (valve, lever).
Water mixers are divided into:
The set for the two-vented mixer includes either a worm-gear box with a rubber gasket or a ceramic box with a rubber gasket.
The worm-gear box is less reliable due to the wear of the rubber gasket during the mixing of water. The gasket is attached to the water supply screw, and when the screw is loosened and tightened, the gasket moves, opening or shutting off the water supply.
The ceramic crane axle box is more durable due to the simplicity of the design. This mechanism consists of two ceramic discs, one of which is stationary, and the other is attached to the stem. When the valve is turned, the holes on the discs are aligned, allowing water to flow into the mixer.
Moving the lever vertically, you can adjust the water pressure, and moving the lever horizontally helps to change the water temperature.
By design, there are two types: ball and ceramic cartridges.
In the body of the ball mixer, there is a hollow ball with holes for the water supply and a pin that is connected to the mixer handle. The pressure and water temperature are adjusted by turning the ball, which aligns the holes of the ball and the body. The cuffs and gaskets that fix the ball mechanism wear out quickly, which can cause the mixer to leak.
Almost all manufacturers have switched to ceramic cartridges.
The mixer with ceramic cartridge consists of two plates. When you shift or turn these plates, the holes for the water supply are aligned, so it is mixed and poured out.
Bath and shower mixers are equipped with a "Bath - Shower" switch that switches water flow between spout and hand shower. Also, these mixers usually have a short but wide spout. This is to fill the tub quickly.
These are single-lever mixers, which have an additional valve for the supply of filtered water. The second spout connects to the filter and supplies the already filtered water to the sink mixer.
The thermostat provides a water supply of strictly selected temperature and pressure, ensuring against unpleasant surprises during water procedures.
Two knobs are used to control the thermostatic mixer: with the first one, you may turn on the water and regulate its pressure; with the help of the second one, the water is being pumped.
Principle of operation: when the mixer is turned on, hot and cold water is supplied to the thermostatic cartridge. Depending on the mixed water temperature, the wax in the flask expands or contracts, thereby moving the valve and regulating the flow of incoming cold water.
For example, if the water is too hot, the wax inside the mixer expands. As a result, less hot water comes from the water supply system. If the water is too cold, more hot water comes from the water supply system, equalizing the water temperature.
It is equipped with a sensor that supplies water when hands approach. It automatically shuts off the water supply if there is no movement.
Using a special lever, the optimal water temperature is set.
These mixers are usually installed in public places to save water, for example, in shopping centers.
Cascade mixers come in various forms of design. They differ from conventional mixers in the shape of the spout, from which water flows out in a wide stream, reminiscent of a waterfall. The disadvantage of cascade mixers is their high cost.
Mixers with separate taps have two independent taps, each controlled by its own flywheel.
Simple and reliable, but not easy to use.
The shower column is a system consisting of several watering cans. On top of the shower, the rack is a large stationary watering can. In addition to the shower column, a hand shower with a flexible hose is attached. The shower rack is installed both in the shower cubicle and in the bathtub.Ceiling shower
Also called a rain shower. Built into the ceiling above the bathtub or shower.
Air is added to the water in a certain ratio, which ensures that water is supplied not by jets but by drops.
The bidet mixer is like a sink mixer. For ease of use, the spout is complemented with an aerator with a ball hinge, which allows you to choose the desired direction of water supply.
A mixer with a hygienic shower can be installed instead of a full-fledged bidet.
