Definitions

  • the present invention relates to a valve for a compressed gas container.
  • a compressed gas tank is a container whose contents are under pressure and is discharged by actuation of the valve.
  • the compressed gas container can also be regarded as an aerosol container.
  • a dispenser for a flowable medium and a dispenser with such a dispenser.
  • the dispenser includes a valve device located downstream in the product dispensing channel.
  • the valve arrangement is designed as a pressure relief valve which opens at a certain overpressure in the container interior and allows an unwanted escape of the medium.
  • the pressure relief valve is designed as a diaphragm valve, which is provided with a cross slot and opens automatically from a predetermined pressure drop within the product discharge channel to the outside for the delivery of a medium.
  • valve for compressed gas packages in which the valve member has a transverse bore which is closed by a pressure device.
  • a pressure device for the pressure device, a number of approaches are known.
  • a spring-loaded plug or a thick disc for closing the transverse bore.
  • the invention has for its object to provide a valve for a compressed gas tank, which allows the simplest possible means a pressure equalization of the container interior and also suitable for very high pressures.
  • the valve according to the invention is provided for a container whose gas filling is under pressure.
  • the valve has an elongated valve housing, a valve member and a sealing element.
  • the elongated valve housing is held at one end in a valve plate and surrounds a channel for the medium to be discharged.
  • the valve member is partially disposed in the channel of the valve housing and protrudes from the valve housing at its end held.
  • the valve is actuated, wherein on the valve member, for example, a spray head or other actuator can be placed.
  • the valve according to the invention has a sealing element which surrounds the valve member sealingly and whose position is fixed to the valve housing.
  • the valve member has an outlet channel, which can be brought via at least one transverse bore in connection with the channel of the valve housing.
  • the valve member For discharging the medium from the compressed gas container, the valve member is brought into a position so that it is not closed by the sealing element and the container interior is connected via the channel in the valve housing with the outlet channel of the valve member.
  • the outlet channel of the valve member is additionally provided at its base with a bore through which the outlet channel of the valve member is in communication with the channel of the valve housing. The bore is closed by a spring-biased valve body, which at a predetermined pressure in the channel of the valve housing against the Spring force is moved out of the bore and releases a direct connection between the channel of the valve housing and the outlet channel of the valve member.
  • the valve member is provided with an additional bore.
  • the spring-biased valve body is arranged independently of the actuation of the valve member in this. In a regular actuation of the valve member of the valve closing the bore body remains in its sealing position.
  • This has the advantage that the overpressure at which the valve body is removed from the bore, regardless of the otherwise prevailing in the operation of the valve pressure can be selected.
  • a briefly occurring overpressure opens the compressed gas tank only briefly. Once the pressure is insufficient to remove the valve body from the bore, the valve member is closed by the valve body again and can be operated again regularly.
  • a ball is provided as the valve body. Also preferably, the bore in the outlet channel on a valve seat for the valve body.
  • the valve member is at its end facing away from the valve plate with a chamber in the outlet channel provided in which the valve body and its spring are arranged.
  • the regularly used discharge channel can be dimensioned independently of the dimensions of the chamber.
  • the design of the outlet channel of the valve member is not limited by the dimensions of the chamber.
  • the outlet channel is provided at its end facing the valve head with a mouth portion which is bounded by a circumferential wall of the valve member.
  • the mouth portion may be cylindrical or conical, wherein the mouth portion has a diameter which is greater than twice the wall thickness of the valve member.
  • the chamber is connected in the outlet channel via at least one connecting channel with the mouth portion of the outlet channel.
  • at least one connecting channel By separating the flow paths for the medium in regular use and in the case of overpressure both exit routes for the medium can be dimensioned independently. Due to the at least one connecting channel both areas are interconnected. In a preferred embodiment, the Diameter of the at least one connecting channel smaller than the diameter of the mouth portion.
  • valve member is arranged in its spring-biased position in the valve housing such that the transverse bore is closed by the sealing element or projects out of the valve housing. In the shifted against the spring force position of the valve member, this is arranged in the valve housing such that the transverse bore is in communication with the channel of the valve housing. In the regular operation of the valve member, this is axially displaced into the valve housing, wherein the valve body completely arranged within the valve body and its spring are moved without them open.
  • the force acting on the valve member spring is disposed in the valve housing and engages the end facing away from the valve plate end of the valve member.
  • the channel in the valve housing preferably has a shoulder which limits the displacement of the valve member into the valve housing. In this way it can be ensured that the valve member is not pushed too far into the valve housing. Further, the valve member with projections provided which rest in the advanced position of the valve member to the sealing element.
  • the sealing element is preferably designed as a ring having a circumferential annular body and a circumferential sealing lip, which rests against the valve member.
  • the sealing element is seated in an annular recess of the valve housing, which is delimited by the valve disk, wherein expediently the sealing element is clamped between the valve disk and the valve housing.
  • valve member has a body which is closed at its end facing away from the valve disc end by a closing element, wherein the closing element has the closed by the spring-biased valve body bore.
  • Fig. 1 shows in a sectional view of the valve 10 according to the invention.
  • the valve has a dome-shaped valve plate 12, in which the valve housing 14 is held with a compression deformation.
  • the valve housing 14 has an elongate shape which projects into the container (not shown).
  • the valve housing has at its end remote from the valve plate 12 end an inlet opening 16 for the medium to be discharged.
  • the medium to be discharged may be gas or a liquid.
  • the valve according to the invention can be used for a compressed gas container in which liquid carbon dioxide is stored.
  • the special feature of liquid carbon dioxide is that it can already assume a pressure of 50 bar at room temperature, so that a pressure compensation for the pressure vessel is required.
  • Adjoining the inlet opening 16 is a channel 18, which extends through the entire valve housing and has a chamber 20 downstream of the medium to be discharged.
  • the chamber 20 has at its upstream base a shoulder 22 on which a spring 24 is supported.
  • a valve member 26 is arranged, which has a mouth portion 28.
  • the mouth portion 28 widens in the valve member consists of an elongated body 66 which forms the outlet channel, and a closure element 42.
  • the valve member 26 has below the mouth portion 28 has a transverse bore 32 through which the medium to be discharged enters the valve member , Upstream of the mouth portion 28, two connecting channels 34 are shown in the illustrated embodiment, which connect the mouth portion with a chamber 36.
  • a spring 38 and serving as a valve body ball 40 is provided in the chamber 36 of the valve member.
  • the ball 40 is pressed by the spring 38 onto a valve seat 44 formed by a closing element 42 (cf. Fig. 2 ).
  • the end member 42 is latchingly inserted in the body 66 of the valve member 26 at its upstream end.
  • the end member 42 has a bore 46 which connects the chamber 36 of the valve member with the chamber 20 of the valve housing.
  • the chamber 20 in the valve housing 14 is connected via an annular gap 48 (see. Fig. 2 ) in communication with an exit chamber 50.
  • the downstream end of the outlet chamber 50 is closed by a sealing element 52 which is arranged in a recess 64 of the valve housing 14 and is held by the valve plate 12 therein.
  • the sealing element 52 has an annular body 54, which merges into a sealing lip 56. Between Sealing lip 56 and annular body 54 is a circumferential recess 58 which allows an elastic deformation of the sealing lip 56 in the radial direction.
  • chamber 36, connecting channel 34 and mouth portion 28 are components of extending through the valve member channel.
  • Fig. 1 the valve according to the invention is shown in its regular open position.
  • the transverse bore 32 is not sealed by the sealing lip 56, but is located in the outlet chamber 50.
  • the outlet chamber 50 is supplied via the annular gap 48, the chamber 20 and the outlet channel 18 with medium.
  • the valve member 26 is pressed against the force of the spring 24 in the valve housing 14.
  • the movement of the valve member 26 in the valve housing is limited by the shoulder 62 in the valve housing.
  • the shoulder 62 is located at the downstream end of the chamber 20.
  • the transverse bore 32 moves inwardly in the valve member and is released by the sealing lip 56.
  • the pressurized medium then passes via the outlet channel 18 and the chamber 20 past the valve member via the transverse bore 32 in the mouth portion 28 a.
  • the valve member 26 may be pressed by a spray head or the like into the valve housing, for example, so as to allow the medium to escape.
  • valve member 26 In its closed position, ie in its advanced position, the valve member 26 is advanced so far, provided on the outside of the valve member projections 60 abut the lower edge of the sealing lip 56. In this position, the transverse bore is either still in the region of the sealing lip 56 and is sealed by this or the transverse bore is pushed beyond this out of the valve housing.
  • the depression 58 on the sealing element 52 additionally assists the sealing engagement of the sealing lip 56 on the outer wall of the valve member 26.
  • the medium under pressure in the chamber 50 likewise enters the depression 58 of the sealing element 52 and presses the sealing lip 56 against the valve member 26.
  • the medium presses through the bore 46 in the closure element 42 against the valve body 40 FIGS. 3 and 4 shown, the valve body 40 lifts from its sealing seat 44 against the force of the spring 38 at.
  • the medium passes past the valve body into the chamber 36 of the valve member and via the connecting channels 34 in the Mouth section 28 to exit via the outlet channel 30.
  • the discharge of the medium takes place as long as the overpressure in the bore 46 and thus in the container interior is large enough to lift the valve body 40 from its sealing seat 44.
  • a particular advantage of the valve according to the invention is that the medium is guided centrally through the valve member at an overpressure occurring, so that at overpressure the pressure in the outlet chamber 50 and in particular on the sealing element 52 is less than at the inlet opening 16.
