Definitions

  • the present invention relates to a hydrant according to the preamble of claim 1 and a method for disassembling a spindle assembly from a hydrant.
  • Hydrants are connected to a water distribution system and represent a valve for withdrawing water, allowing the fire department, as well as public and private users, to draw water from the public water distribution system.
  • the network pressure in the water distribution system is typically approximately 6 to 9 bar.
  • Hydrants are generally divided into two types: pillar hydrants and underground hydrants.
  • the pillar hydrant is permanently installed above ground and has outlets with standardized couplings.
  • the underground hydrant is installed underground and concealed from above by a ground cover.
  • the underground hydrant is a water extraction point located below ground level, which is closed off by the ground cover.
  • Hydrants comprise a riser pipe with an interior and an exterior, with the interior leading into the water outlet.
  • a main valve which consists of a main valve body and a sealable sealing seat.
  • the main valve body is connected to one end of a valve rod, through which the main valve body can be guided axially up and down.
  • a spindle assembly is provided, which comprises a spindle cover attachable to the riser pipe, a spindle rotatably mounted on the spindle cover, and a spindle nut coupled to the valve rod at another end.
  • the spindle and spindle nut are in mutual threaded engagement.
  • the spindle assembly converts a torque applied to the spindle into an axial adjustment of the valve rod and thus of the main valve body.
  • the hydrant requires an overhaul, e.g. an overhaul of the main valve, replacement of the main valve body, cleaning of the valve seat, replacement of other components, etc.
  • the spindle assembly or main valve To disassemble the spindle assembly or main valve, it is common practice to cut off the water supply to the hydrant, e.g., by isolating it from the water supply using an upstream shut-off device, such as a gate valve. As soon as the water pressure at the hydrant is no longer present, the spindle cover is released from the riser pipe, e.g., by loosening the screws. The spindle assembly or main valve can then be removed upwards from the riser pipe by applying a pulling force to, for example, the spindle cover. However, the main valve body is tightly seated against the sealing seat.
  • an upstream shut-off device such as a gate valve.
  • the printed matter DE4243756A or CH01381B show a typical hydrant and its dismantling.
  • a hydrant according to the invention comprises a riser pipe and a main valve, which includes a main valve body, a sealing seat sealable with the main valve body, a valve rod connected to the main valve body at one end, and a spindle assembly.
  • the spindle assembly includes a spindle cover attachable to the riser pipe, a spindle rotatably mounted on the spindle cover, and a spindle nut coupled to the valve rod at another end.
  • the spindle and the spindle nut are mutually threadedly engaged, designed to convert a torque applied to the spindle into an axial adjustment of the valve rod.
  • the spindle assembly further includes a pin/pin support assembly, comprising at least one pin and at least one pin support, wherein the pin support has a first support and a second support against which the pin can be brought into contact.
  • the hydrant according to the present invention is characterized by the fact that the spindle assembly or main valve can be removed from the riser pipe via the spindle cover without the need for separate tools and simultaneously installed into the riser pipe. Furthermore, the respective procedures are self-explanatory and can be carried out quickly and easily on-site. Furthermore, the procedures can be carried out quickly and easily even on hydrants that are difficult to access.
  • the riser pipe is provided with at least one pin support, which has a first and second support. At least one pin is formed on the spindle cover, which can be brought into contact with the first and second support. As soon as the pin is in contact with a corresponding one of the supports, the spindle can be rotated in a direction in which the spindle assembly or the main valve is either pushed upwards to pull the main valve body out of the sealing seat, or pushed downwards to press the main valve body into the sealing seat. For this purpose, the rotary movement is converted into the necessary translational movement by means of the spindle assembly. The force generated here is introduced via the pin of the spindle cover into the respective support in the riser pipe.
  • the spindle nut In counteraction, with continued rotation of the spindle, the spindle nut is adjusted axially and This axially adjusts the valve stem and the main valve body. As the main valve body is raised, it increasingly moves out of its fixed contact or radial compression with the sealing seat until a height is reached at which the main valve body is released from the sealing seat.
  • the spindle can be rotated via an outwardly extending coupling element, e.g., a square drive, that is rigidly connected to the spindle.
  • the main valve can be removed upwards from the riser pipe.
  • "removal of the main valve from the riser pipe” refers to the removal of an assembly comprising: the main valve body, the valve rod connected to it, the spindle assembly coupled to it at the other end, and the spindle cover rotatably coupled to the spindle.
  • This assembly is sometimes also referred to as the "rod assembly.”
  • the main valve can be reinstalled into the riser pipe using a reciprocal method.
  • the main valve body is simply pressed into the sealing seat by rotating the spindle.
  • the spindle assembly already installed in the hydrant is used, or rather “converted", in conjunction with the pin/pin support assembly to convert a rotary movement applied to the spindle into a force between the spindle cover and This force is transferred to the spindle nut of the spindle assembly, allowing the spindle nut, valve stem, and main valve body to be adjusted axially.
  • the main valve body is either raised or lowered depending on the direction of rotation of the spindle.
  • a hydrant wrench for example, can be used to turn the spindle; this wrench is typically used to open and close hydrants. Such a hydrant wrench is always carried during all work involving hydrants and does not need to be kept separately.
  • the first support and second support are offset from one another.
  • the first support and second support can be offset from one another when viewed in the axial direction of the riser pipe.
  • the first support and second support can be spaced apart from one another, also when viewed in the axial direction of the riser pipe.
  • the pin is attached to the spindle cover and the pin support is provided in the riser pipe.
  • the pin can be brought into contact with the first support from below, and the pin can be brought into contact with the second support from above.
  • a force can be introduced into it from above (by turning the spindle in one direction).
  • the main valve body is moved upwards.
  • a force can be introduced into it from below (by turning the spindle in the opposite direction).
  • the main valve body is moved downwards.
  • the riser pipe is provided with a pin guide in which the pin can be guided, the pin guide comprising: a first guide section in which the pin can be guided in the axial direction of the spindle, the first guide section being delimited at least in sections upwards by the first support, and a second guide section in which the pin can be guided in the axial direction of the spindle, the second guide section being delimited at least in sections downwards by the second support.
  • first and second guide sections are offset from each other at least in sections.
  • the first and second Guide sections can be offset from each other, viewed in the axial direction of the riser pipe.
  • the first and second guide sections overlap at least partially in a section between the first and second supports.
  • the pin can be moved upwards over the first guide section.
  • the spindle cover can be pivoted so that the pin enters the second guide section.
  • the pin can be moved downwards by reversing the direction of spindle rotation until the pin comes into contact with the second support.
  • a force can be applied against it from above. This force is diverted into the spindle nut by continued turning, as a result of which the main valve body is moved upwards.
  • the pin can be transferred from the second guide section to the first guide section. From there, the pin can be brought into contact with the first support from below. Once the pin is brought into contact with the first support, a force can be applied against it from below. This force is transferred into the spindle nut by continued rotation, resulting in the main valve body being moved downward.
  • the pin guide is designed as a recess in the riser pipe.
  • the pin guide can be designed as a recess or groove cut into the material of the riser pipe.
  • the pin is substantially L-shaped, comprising a projection that, viewed in the radial direction of the spindle cover, is directed outward, wherein the projection can be brought into contact with the first and second supports.
  • the projection engages in the pin guide.
  • the projection engages in the first and second guide sections of the pin guide and is reliably guided axially therein.
  • the projection forms a counterbearing, via which the pin of the spindle cover can be brought into contact with the first or second support and can introduce a force.
  • the riser pipe is perforated upwards in the area of the second guide section.
  • the spindle assembly can be easily removed from the riser pipe through the perforation.
  • the spindle cover can be screwed onto the riser pipe.
  • the predetermined height can comprise a height of the spindle cover from which the spindle cover can be rotated or pivoted such that the pin, viewed in the axial direction of the riser pipe, can be aligned at least partially with the second support.
  • the spindle cover can be guided or rotated by rotating the spindle in the direction of lowering the spindle cover such that the pin, viewed in the axial direction of the riser pipe, can be aligned with the second support.
  • the spindle cover can therefore rotate with the applied rotation, so that the spindle cover does not have to be pivoted by hand.
  • the spindle cover can also be pivoted by hand such that the pin, viewed in the axial direction of the riser pipe, is aligned with the second support.
  • the hydrant 10 comprises a riser pipe 14 and a main valve 16.
  • the main valve 16 comprises a main valve body 18, which can be brought into sealing engagement with a sealing seat 20 formed in the riser pipe 14.

  • the spindle nut 32 is coupled to the upper end of the valve rod 22 via a coupling/guide arrangement 34, designed to convert a torque applied to the spindle 28 into an axial adjustment of the valve rod 22.
  • the coupling/guide arrangement 34 includes a radially outwardly directed extension 36, which engages in a longitudinal groove 38 formed in the interior of the riser tube 14 and can be guided therein only in the axial direction of the riser tube 14. As a result, the coupling/guide arrangement 34 and thus the valve rod 22 coupled thereto are adjustable only in the axial direction of the riser tube 14.
