Definitions

  • the present invention relates to a valve for connection to a pressure source according to the features in the preamble of claim 1.
  • an extinguishing gas primarily CO2
  • CO2 can be provided in pressure bottles and, if required, transported to the site of use via pipes by manual or automatic activation.
  • operating pressures of more than 100 bar up to 150 bar are stored.
  • the present invention therefore has the object of showing a possibility to improve safety and user-friendliness in the aforementioned applications with high pressures.
  • the valve is used to connect to a pressure source and to transmit the pressure to at least one consumer.
  • the valve is preferably a bottle valve and the pressure source is preferably a pressure bottle.
  • the valve is suitable for operating pressures of up to 300 bar.
  • the consumer is, for example, a fire protection system or a pneumatic hand tool.
  • a gaseous pressure medium is used in particular as the pressure medium.
  • the valve has a valve body.
  • the valve body has a pressure channel.
  • the pressure channel is used to connect the pressure medium in the pressure source and to transmit it to a line, in particular a hose, in order to transmit the pressure medium to the consumer when required. In the operating state, the bottle valve is therefore open and the operating pressure is present in the pressure channel and in the line at the consumer.
  • a vent valve is now incorporated in the pressure channel. It is provided that, for example, by closing the valve, in particular the bottle valve, the pressure still in the line and in the pressure channel can then be released to the environment via the vent valve.
  • the line, in particular the hose can then be separated from the valve or the consumer must be separated from the hose. Ideally, ambient pressure will then be present in the pressure channel or the line or the hose.
  • the vent valve has an axially movable bolt that is held in an operating position.
  • the bolt of the vent valve In the initial state, the bolt of the vent valve is thus held in the operating position and the pressure source is thus connected to the pressure channel and the lines connected to the pressure channel in a pressure-conducting manner.
  • the pressure in the pressure channel By axially moving the bolt into a venting position, the pressure in the pressure channel can be released into the environment.
  • the vent valve with an axially movable bolt is therefore much easier to operate, as the position of the vent valve can be seen visually in the operating position.
  • the pressure can be released by simply pressing it, for example with a thumb and moving the bolt in the axial direction.
  • the bolt is held in the operating position against a spring force. This has the advantage that the pressure can be released at will by pressing the bolt in, and as soon as a force, for example applied by the hand or thumb of an operating mechanic, is released from the bolt, it returns to the operating position and no further venting takes place.
  • the vent valve itself has a mechanically robust, solid and simple structure. It is formed in particular from an outer sleeve. Alternatively, it is preferably also possible for the previously described movable bolt to be integrated directly into the valve. In this case, a recess or a multi-stage bore with different diameters is integrated directly into the valve or bore. All of the following statements regarding the sleeve or inner surface of the sleeve in conjunction with the bolt therefore also apply to direct integration into the valve.
  • the outer sleeve can preferably be pushed into the higher-level valve.
  • the wall of the sleeve has openings that pass through it and are connected to the pressure channel in a fluid-conducting manner.
  • the bolt is mounted in the sleeve so that it passes through the sleeve axially.
  • a pressure chamber is preferably formed between the sleeve and the bolt.
  • the bolt itself is designed to be constricted or tapered or reduced in its pressure gauge. Seals are incorporated at an axial distance from the tapering or the recesses in the walls of the sleeve, so that the pressure chamber is formed.
  • a spring is particularly preferably arranged at one axial end, the spring holding the bolt in the operating position.
  • an abutment is formed in the sleeve of the vent valve and in the bolt, so that in the operating position the spring holds the bolt in the operating position against the stop of the abutment.
  • the bolt has a sealing ring in the area of one end.
  • an additional seal is placed in the axial direction upstream of the actual sealing ring.
  • the actual sealing ring completely seals the pressure chamber between the operating pressure and the ambient pressure.
  • the additional seal preferably does not have a 100% sealing function, so that there is a lower operating pressure between the additional seal and the sealing ring, but this is higher than the ambient pressure.
  • the additional seal can also be referred to as a sacrificial seal.
  • the additional seal has an opening which passes through the wall of the additional seal.
  • the additional seal itself is designed as a sealing ring.
  • the opening particularly preferably passes through the wall itself in the radial direction and is designed as a slot which runs radially around sections. This in turn ensures that when the opening of the additional seal passes the widening, pressure is initially released or vented here. Thus, when the additional seal is completely passed, the resulting pressure surge is reduced in its peak or intensity.
  • vent valve is arranged transversely to the course of the pressure channel. This makes it easier to operate and operate the vent valve.
  • Figure 1 shows the valve according to the invention in longitudinal section
  • FIG. 4 Representation of the vent valve according to Figure 2 and
  • FIG. 5 Representation of the vent valve according to Figure 3.
  • Figures 6 to 8 show an alternative design variant to Figures 1 to 3 with direct integration of the bolt into the valve body in a Longitudinal section view and two cross-sectional views analogous to Figures 2 and 3,
  • Figure 1 shows a valve 1 in longitudinal section. According to the invention, a vent valve 2 is inserted into the valve 1.
  • the valve 1 itself is used to attach to an indicated pressure source 3 in the form of a pressure bottle.
  • a pressure channel 4 is formed, which passes on an operating pressure of the pressure source 3 via the pressure channel 4.
  • a screw connection 5 is also provided so that the connected pressure source 3 can be opened or closed.
  • An operating pressure can be displayed via a pressure gauge 6.
  • a connection 7 is also provided.
  • a consumer can be connected to the connection 7, in particular via a hose line (not shown in detail).
  • the connection 7 can also be provided for filling the pressure source 3.
  • a closure 8 seals the pressure channel 4 with respect to the pressure source 3.
  • the connection 7 is connected to the pressure channel 4 in a fluid-conducting manner. If the venting position according to Figure 3 is thus assumed and the screw connection 5 is closed until the pressure source is sealed, the pressure channel 4 is vented to the environment U.
  • FIG. 2 shows a cross-sectional view along the section line A-A according to Figure 1.
  • the vent valve 2 is inserted into the valve 1 transversely to the pressure channel 4.
  • the valve 1 has a receiving opening 9 in the form of a complex bore.
  • the vent valve 2 is inserted transversely.
  • Various seals 10 are provided on the outside, which seal the vent valve 2 with the valve 1 with regard to its pressure channel 4.
  • FIG 3 shows the view according to Figure 2, wherein the vent valve 2 is not shown in an operating position as in Figure 2, but in a venting position.
  • a bolt 12 is displaced in the axial direction to an outer sleeve 13.
  • a pressure chamber 14 of the vent valve 2, located in Figure 2 is connected to the environment U in a fluid-conducting manner.
  • a hose connection 16 This is used to fill the pressure source 3 and preferably has a backflow preventer or check valve.
  • the hose connection 16 does not necessarily have to be provided and can also be omitted.
  • the pressure source 3 can then be filled via the connection 7 as already described at the beginning.
  • FIGS 4 and 5 each show detailed representations of the vent valve 2 according to Figures 2 and 3.
  • the vent valve 2 has an outer sleeve 13 and an axially displaceable bolt 12 in the sleeve 13.
  • the bolt 12 can also be referred to as a piston.
  • the bolt 12 is held in the operating position shown in Figure 4 against a spring force (F).
  • F spring force
  • a stop is provided between the bolt 12 and the sleeve 13.
  • the bolt 12 is covered by a cap 19. Inside the cap
  • a grub screw 20 is provided so that the bolt 12 holds the compression spring 17 and the compression spring 17 simultaneously applies a spring force (F) to the bolt 12.
  • a pressure chamber 14 is formed between the inner surface 21 of the sleeve 13 and the bolt 12.
  • the pressure chamber 14 is fed with the operating pressure from the outside via the recesses 11 located in the surface of the sleeve 13, such that the operating pressure is also present in the pressure chamber 14. If the venting position shown in Figure 5 is now assumed, the bolt 12 is moved to the left in the axial direction A in the image plane.
  • the pressure chamber 14 is thus connected to the environment U in a fluid-conducting manner.
  • the sleeve 13 is initially widened on its inner surface 21 in an axial end section.
  • the additional seal 23 can be designed as a square or rectangular seal.
  • the seal first passes the expanded inner surface 21 as the main seal, with the additional seal 23 then sealing the pressure chamber 14 from the environment U. Only at a later point in time, namely when the bolt 12 is pushed further into the sleeve 13, does the additional seal 23 then also pass through the expanded inner surface 21 and release the operating pressure in the pressure chamber 14 to the environment U.
  • the actual seal 22 is thus not fully affected by the initial pressure surge itself, since the pressure surge is weakened in its intensity by the additional seal 23.
  • a slot 24 formed in the radial direction R is also present, penetrating the wall of the additional seal 23. Through this slot 24, an initial pressure maximum of the pressure surge can escape to the environment U while it is passing through the expanded inner surface 21, thereby reducing the intensity of the pressure surge.
  • the slot 24 is formed in the additional seal 23 in radial sections, running around and oriented in the radial direction.
