Definitions

  • the present invention refers to a thermostat-controlled mixing valve for two liquids, e.g. hot and cold water, and of the kind comprising a housing provided with an outlet and an inlet each for the liquids, a first operation member for regulating the amount of the liquid flowing out through the outlet and a second operation member for regulating the temperature of the liquid by means of a temperature respon- sive element cooperating with a control member for regula ⁇ ting the inflow areas of the liquids, said control member is axially displaceable in the housing.
  • Such mixing valves usually comprise several parts held together by threaded joints, said parts form inlet channels for the liquids to the temperature responsive element and an outlet channel for the mixed liquid. These parts must be sealed with respect to each other and the mounting thereof is often complicated and time-consuming.
  • the object of the present invention is to provide a mixing valve of the kind mentioned above, which has a simple and compact design and in which the inlet and outlet channels are built-in in one single unit.
  • the thermostatic mixing valve comprises an elongated housing 1, at one end i which an inlet 2 for e.g. cold water is arranged and at the opposite end of which an inlet 3 for e.g. hot water is arranged. At the middle part of the hou ⁇ sing 1 an outlet 4 for mixed tempered water is arranged.
  • the flow of the mixed water can be adjusted by a first operation member 5 cooperating with a stop valve 6 and the temperature of the water is adjusted by means of a second operation member 7.
  • a sleeve-shaped insert 8 which is sealed with respect to the housing and provides in- and outlet channels for the water through the housing.
  • a spring 9 acts upon an end piece 14 to the insert 8.
  • a temperature responsive element 10 and a control member 11 cooperating therewith.
  • the control member 11 comprises a sleeve which is displace- able in axial direction in the insert 8 and which has a radial partition wall 12 held in close contact with the temperature responsive element 10 by a spring 13, the abut- ting surface of which consists of the end piece 14.
  • the spring 13 bears against the bottom of the control member 11, the partition wall 12, just opposite the contact surface thereof with the temperature responsive element 10. By this it is prevented that the control member tips when it is exerted to a pressing force from the spring 13.
  • the control member 11 is guided by the end piece 14 of the insert 8 along its outside as well as its inside, at which tipping over is prevented when a pressing force is exerted by the temperature responsive element 10.
  • the insert 8 has double axial partition walls 15 and 16 between the.inlet 2 and the control member 11, at which the space between the walls 15 and 16 makes a flow channel 17 for the liquid from the inlet 2, e.g. the cold water.
  • the end edge 16' of the inner partition wall 16 makes in coope ⁇ ration with the control member 11 a control slot for the cold water.
  • the control slot for the hot water is formed between the opposite end of the control member 11 and a circumferential edge 14' of the end piece 14 of the insert 8, located in connection to a number of radial openings 14' ' in the end piece 14.
  • the mixed water flows towards the outlet 4 via the passage 18 that is formed inside the inner partition wall 16 and about the temperature responsive element 10.
  • the partition walls 15 and 16 are inter- connected and form a ring-shaped outlet channel 19 for the mixed water.
  • the outer end edge 19' of the outlet channel 19 forms a sealing surface for the stop valve 6.
  • the control member 11 is by means of the second operation member 7 axially displaceable in the housing 1 by way of a spindle 20, which is threaded in a sleeve 21, which with a radial wall 22 bears against the temperature responsive element 10.
  • a spindle 20 which is threaded in a sleeve 21, which with a radial wall 22 bears against the temperature responsive element 10.
  • the insert 8 is preferably manufactured by plastic material, which gives a cheap manufacture and simple mounting, since snap-in locks can be used instead of threaded joints.
  • a further advantage is that all functional parts can be manu- factured by.plastic material, at which the corrosion problem is eliminated. Corrosion is a serious problem for details of copper alloys, which are used in conventional mixing valves.
  • the end piece 14 which is connected through a threaded joint is moveable in axial direction with respect to the rest of the insert 8 against the action of the spring, at which excess motions of the temperature responsive element 10 can be compensated.

Abstract

Vanne de mélange d'eau chaude et froide commandée par thermostat. On a agencé dans le logement de mélange (1) une insertion (8) d'une pièce dans laquelle sont disposés un élément (10) réagissant à la température ainsi qu'un élément (11) de commande coopérants. Ladite insertion (8) comporte sur une partie de sa longueur des doubles parois de cloisonnement axiales (15, 16) au niveau desquelles l'espace situé entre les parois forme un canal d'écoulement soit pour l'eau chaude soit pour l'eau mélangée, à l'intérieur de la paroi de cloisonnement. Une partie de raccordement se trouvant entre les deux parois de cloisonnment (15, 16) forme un canal de sortie (19) pour l'eau mélangée. Le bord terminal extérieur (19') du canal de sortie (19) forme de préférence une surface d'étanchéité pour une vanne d'arrêt (6).
