Problems solved by technology

Thus they do not work correctly, for example the sliders can get stuck and thus affect the operation of the device
[0006] The second defect comes from calcareous scaling, especially on the hot water side, which jeopardizes accurate operation of the unit
Also, thermostats are subject to loads that do not depend on their specific operation

Embodiment Construction

[0023] refer to figure 1 and 2 , it can be seen that the valve according to the present invention comprises a valve group, which is further described in more detail and includes a movable upper plate 5, a fixed lower plate 4, a lower gasket 3 and a base 2. The relevant gasket 1 is arranged under the valve group to install inside the faucet. Lateral openings C, F for inflow of hot and cold water respectively and a central opening M for outflow of mixed water are formed in the base 2 .

[0024] Arranged in the valve block is a lower spring 6 which pushes from below a slider 8 which slides sealingly inside the disc 5 thanks to an O-ring 7 and which is pushed from above by a thermostatic element 9 passing through it. An insert 10 is screwed onto the thermostatic element 9 , said insert 10 being guided sealingly by means of an O-ring 11 into a central opening of an element 13 transmitting flow rate control.

[0025] The upper surface of the upper disc 5 is also pressed sealingly...

Abstract

The invention relates to a thermostatic mixing valve in which the access path of the hot water to the mixing chamber is completely formed within a bottom base (2) and the ceramic disks (4, 5) of the valve group, the slider (8) of the thermostatic member sealingly sliding in a central seat of the upper disk (5). By having the hot water not pass through the metallic members of the valve it is possible to eliminate the problems of asymmetric thermal expansion of said metallic members when only hot water is delivered, and also to greatly reduce the problems of calcareous encrustations since the latter build up with difficulty on the ceramic material. Furthermore, the valve is manufactured with a compact and simplified structure, including a small number of pieces, with totally independent temperature and flow rate controls.

Description

technical field [0001] The present invention relates to taps for mixing hot and cold water in sanitary installations (basins, sprinklers, bathtubs, etc.), and more particularly to a tubular mixing valve with a thermostat adapted to maintain a constant water temperature. Background technique [0002] Conventional individually controlled mixing valves are known which comprise a tap body with a pipe-type mixing valve (hereinafter referred to simply as valve) detachably inserted therein and a lever for controlling a valve group inside said pipe, said valve group Consists of a pair of ceramic discs that regulate the flow of hot and cold water. The adjustment of the flow rate and temperature of the water is achieved through the translation and rotation of the moving plate on the upper part of the fixed plate below, respectively. In this way, the size of the holes formed on the plate for the passage openings through which the hot water and the cold water flow are changed, and the ...
