Abstract

Improvements in the construction of thermostatic valves, characterized by the fact that the valve is constituted by a body, with cylindrical internal walls, in which at one end of the tube there is the entrance of the liquid coming from the supply network, then of which there is a housing chamber for closing the valve, constituted by a circular body, with a cylindrical neck, which supports, constantly, against the seat of said head, located on the internal wall of this first chamber, of which head part, diametrically, a cylindrical shank, which enters a second chamber, arranged after the first and passing through the hole, located in the separation wall of both chambers, ends its end inside a tubular compartment horizontal that on the other side is inserted the end of a piston, conical tip, which in turn is contained in the side mouth of a tank or of a fluid of high power of contraction and expansion according to the temperature degree of the environment in which its continent is located, such as freon and the container containing the fluid and the piston, is in turn housed in a third general chamber , located next to the other two, in which chamber there are the supports of the tank so that it, smaller in diameter than the internal walls of the tube, is fixed and with due separation, so that there is an annular chamber around it and being provided in the external body of the valve, tubular layers, which communicate with its general chamber and thus communicates inside it with the outside of the valve, there being at least three such layers, two found located one near the opposite end to the entrance of the liquid coming from the network and another envelope of the area in which there is the compartment in which are facing the two ends of the On the closing of the valve and the piston of the fluid reservoir, dilatable and contractable, which layers, one receives the steam from the boiler and the intake is higher than the level of the liquid, while the other, output of the steam entering the general chamber of the valve serves as an outlet nozzle for this steam and its communicating tube opens into the useful steam outlet pipe of the interior of the boiler, while the third layer, also communicating with the inside of the valve and located on the periphery of the external tube, it preferably has helicoidal thread on its periphery, from which cold liquid comes from the supply network and enters the valve through the inlet, when the closure of the same it is open, and by means of the opportune conduction, this liquid passes to the interior of the boiler whose content in liquid is regulated, the valve being placed outside the body of the boiler and horizontally, c with respect to the horizontal line of the level of the contained liquid and to the same height as the line of said level.
