Definitions

  • the invention relates to a valve, in particular a radiator valve for hot water heating systems, with a housing, two connecting channels for the inflow and outflow, a valve seat and a closure piece to be actuated from the outside and loaded by a spring and covering the valve seat.
  • valves of this type are designed for a flow direction in which the inlet pressure acts on the closure piece in the opening direction.
  • the closing piece When operating in the opposite direction of flow, the closing piece would be loaded by the inlet pressure in the closing direction, with the result that the force of the opening spring would no longer be sufficient to open the valve.
  • the invention has for its object to provide a valve of the type described above, which can be operated in both flow directions.
  • This object is achieved in that the closure piece on its side facing away from the valve seat has a piston which engages in a sealed manner in a cylinder chamber, the effective pressure area of which is substantially equal to the area enclosed by the valve seat, and in that the cylinder chamber with the space inside the valve seat connected is.
  • the largest surface of the closure piece is therefore relieved of pressure in both flow directions, preferably completely relieved of pressure. There are therefore, if any, only small areas on which pressure acting in the closing direction can act.
  • the closing forces exerted by the medium flowing through are therefore so low that they can be easily overcome by an opening spring. Operation in both flow directions is thus possible.
  • a heating system it is therefore no longer necessary to pay attention to the flow direction, which leads to considerable simplifications. Smaller thermostatic elements with a lower actuating force are sufficient for actuation.
  • closure piece prefferably has at least one channel connecting both end faces. This results in a particularly simple construction.
  • closure piece have an area in which its cross section increases towards the valve seat, and that an annular flange arranged near the free end of the piston partially overlaps this area and is loaded by the pressure acting on the area. The result of the overlap is one partial pressure relief, through which the closing forces are reduced again.
  • the area of the cross-sectional increase is formed by a cone, which is adjoined by a cylindrical section which carries the ring flange.
  • a closure piece can be easily manufactured.
  • the closure piece or the valve seat is preferably made of elastic material. This improves the sealing function.
  • valve seat be surrounded by a circumferential channel.
  • this circumferential channel leads to a pressure increase in both flow directions and a pressure decrease behind the valve seat, so that the forces exerted on the closure piece largely cancel each other out.
  • the circumferential groove has a gradually increasing depth radially from the outside inwards and is delimited by the circumferential wall of an annular wall supporting the valve seat. This gives largely the same conditions for both flow directions.
  • valve seat has a dome shape in cross section.
  • FIG. 1 schematically shows a cross section through a valve according to the invention
  • Fig. 3 shows the area A of FIG. 2 in an enlarged view
  • FIG. 4 shows the representation of FIG. 3 with the flow direction opposite.
  • a valve seat 4 is assigned a closure piece 5, which covers the valve seat 4 with its end face 6.
  • the closure piece 5 can be adjusted from the outside by means of a valve rod 8 guided outwards through a seal 7 against the force of an opening spring, not shown here.
  • the closure piece 5 has on its side facing away from the valve seat 4 a piston 9 which is guided in a sealed manner in a cylinder space 10.
  • This cylinder chamber is connected via channels 11 to the end face 6 of the closure piece 5 and, taking into account the cross-section of the valve rod 8, has a pressure-effective cross-sectional area which is equal to the area enclosed by the valve seat 4.
  • the housing 101 carries an extension 115 which forms the connection channel 102 and the valve seat 104.
  • the other connection channel 103 is located laterally next to the closure piece 105 and is formed by a cutout in the housing 101.
  • the closure piece 105 is actuated by a valve rod 116 which is loaded by an opening spring 117 and is supplemented by a valve pin 108 which is guided outwards by a seal 107.
  • a presetting bush 119 which can be rotated with the aid of a rotary knob 120, as a result of which the cross section of the connecting channel 103 can be changed.
  • the closure piece 105 has a piston 109 which is guided in a sealed manner in a cylinder space 110.
  • the cylinder space is through channels 111 with the end face 106 of the closure piece within the valve seat 104.
  • the pressure-effective cross-section of the cylinder space 110 is equal to the cross-sectional area of the closure piece enclosed by the valve seat 104, so that there is complete pressure relief with respect to the pressure in the connection channel 104.
  • a region 112 with a cross section increasing toward the valve seat 104 is designed as a cone. This is partially overlapped by the ring flange 113 and, like the cone, is acted upon by the pressure in the connection channel 103. Therefore, taking into account the overlap area between the closure piece 105 and the valve seat 104, there is also a largely or complete pressure relief.
  • the closure piece 105 is made of an elastic material.
  • the valve seat 104 is surrounded by a circumferential groove 121. Their radial depth gradually increases from the outside in. It ends on a peripheral wall of the valve seat 104, which is dome-shaped and has the shape of a projecting annular wall 122. In the direction of flow according to FIG.
  • the circumferential trough 121 has the effect that there is a greater reduction in cross-section and thus a corresponding increase in pressure shortly before the valve seat 104 (represented by “++”), while a corresponding increase in cross-section and therefore a decrease in pressure behind the valve seat arises (represented by ""), which results in mutually canceling forces (represented by arrows 122 and 123). Similar conditions with pressure increase before and pressure decrease after the valve seat 104 also result in the opposite flow direction, as is illustrated in FIG. 4.
  • the invention can be used not only in connection with radiator valves, be they manually operated or by means of a thermostatic attachment, but also with any type of valve in which the direction of flow should no longer play a role. It is also of interest that many parts of the new valves are identical to those of the valves on the market, so that larger quantities can be placed and corresponding savings can be achieved. For example, it is sufficient to replace only the closure piece 105 and the extension 115 in order to get to the valve of FIG. 2.

Abstract

L'invention concerne une soupape, en particulier une soupape pour radiateur de chauffage à eau chaude, présentant un boîtier (1), deux canaux de raccordement (2, 3) pour l'alimentation et l'écoulement, un siège de soupape (4), et un élément de fermeture (5) soumis à un ressort, couvrant le siège de soupape (4), et pouvant être actionné depuis l'extérieur. Cet élément de fermeture (5) présente un piston (9) sur le côté opposé au siège de soupape (4). Ce piston est en prise étanche avec une chambre de cylindre (10) dont la surface de pression active est environ égale à la surface renfermée par le siège de soupape (4). La chambre de cylindre (10) est reliée avec la chambre située à l'intérieur du siège de soupape (4). En outre, il est prévu une zone (12) dans laquelle la section de l'élément de fermeture (5) augmente en direction du siège de soupape (4). Une bride annulaire (13) disposée à proximité de l'extrémité libre du piston (9) recouvre partiellement la zone (12), et est soumise à la pression exercée sur cette zone (12). Ainsi, ladite soupape peut être utilisée pour les deux sens d'écoulement.
