Amalgamators (Part 2)
Valve amalgamators are a little bit cheaper than spherical, but they are not so convenient in use and require regular sealants change. But they can be repaired easily, and they are well adapted for any conditions - the rigid chlorinated water. Spherical amalgamators badly transfer firm particles and the salts, dissolved in water, and consequently quickly get broken. In order to repair them, it is necessary to replace completely not too cheap spherical module. However, it is possible to prevent fast (only 4-5 years) fail, having established filters of water treating.
Less often two mentioned above designs are used at cranes with thermostat and pressure equalizer. Two handles are located on each side of such amalgamator, one of which supervises water pressure and the second one, which has a special label, - temperature. In order to receive comfortable temperature, it is necessary to combine only a label of the handle with the necessary figure - and the desirable temperature of water is gained. However, according to experts, such “miracle” is made not always. The matter is that amalgamators with thermostat ?????are not calculated on the changeable water pressure and bad quality of water. Imperfection of water supply system leads to frequent breakages and even failure of such designs.
For today it is possible to consider as the most exotic models are those with a photo cell and touch management. In a design of such amalgamator the lever, which is disconnecting water, is absent, and on the case there is a small screen behind which the infra-red gauge of constant radiation, which is regulating movement of hands, is established. As soon as hands get in an operative range of a beam, it transfers a signal to the device, which supplies water.
