Definitions

  • the present invention is based on one Manual shut-off pistol with anti-twist device for one High-pressure hose, whereby it is only known so far, one such anti-twisting device outside of Arrange manual shut-off gun.
  • This requires separate Nipple devices, being in the range of two to each other associated high-pressure fittings a twisting device is arranged in such a way that hose twists of this twisting device are included, which is in itself twisted and thus this twist does not affect the Manual shut-off gun forwards.
  • the present invention is therefore based on the object an anti-twist device of the type mentioned training much cheaper, easier to design and also save space.
  • the anti-twist device in the Housing is arranged. It is preferred in the valve body integrated. In a currently preferred embodiment the kink protection sleeve, which is usually on such Manual shut-off guns are provided, themselves part of the Anti-twist device.
  • Another advantage of the invention is that standard existing high pressure hoses can be used, which in an associated press sleeve are taken, the Anti-twist device integrated in the valve body itself is.
  • a press-in nipple is rotatably mounted in the valve body and sealed, which press nipple firmly with the high pressure hose and the associated press sleeve is connected, and said three Parts are rotatably mounted in the valve housing and over the Knee protection sleeve are held with a fastening nut.
  • the twisting device press-in nipple
  • the valve device of the manual shut-off gun arranged what with a particularly compact room structure and with the Using fewer construction parts. So that can with few means inexpensive Anti-twisting devices directly in the valve body of the Manual shut-off gun can be integrated.
  • a fastening nut is present, which is threaded on the valve body is screwed on and which the rotatable press-in nipple in Valve housing keeps rotatable so the three parts, namely Turn the press-in nipple, high-pressure hose and press sleeve slightly can.
  • the press-in nipple has a slight axial play in the Location bore of the valve housing for easy rotation to ensure the mentioned parts.
  • a slide ring made of a plastic material, in particular made of Teflon, which is the friction between the press-in nipple and the associated one Fastening nut reduced.
  • a cross-section through a is schematized in the figure Manual shut-off gun shown according to the invention.
  • the manual shut-off gun essentially consists of two housing shells 5 arranged mirror-symmetrically to one another, only one housing shell 5 according to the figure is shown, while the other housing shell is exactly the same is trained.
  • the two housing shells 5 define an in closed housing, which consists essentially of a Rear wall 7, from a front wall 6, from a bottom wall 8 and consists of an end wall 9.
  • An anti-kink sleeve 2 is arranged outside the housing, which the kink protection device has.
  • This Kink protection device consists essentially of a lower, tulip-shaped opening opening to the outside 3, into which the HD hose 4 is inserted, which by means of a press sleeve 20 on a neck of a press-in nipple 18th is kept sealed.
  • a fastening nut 19 is fixed in the anti-kink sleeve 2 arranged that secured against rotation with an associated pin 40 locked in the kink protection sleeve.
  • the press-in nipple 18 with corresponding Sealants on the one hand on the fastening nut 19 and, on the other hand, sealingly engages the valve body 36 and but at the same time is rotatable to the parts mentioned, so that the high pressure hose 4 rotatable in the Manual shut-off gun 1 is held.
  • a slide ring 39 used between the press nipple 18 and the fastening nut 1 ⁇ .
  • the press-in nipple 18 opens into a socket via a shoulder 17, which as a separate nut part in the valve body 36 is screwed in.
  • This socket 17 forms the lower part of the Valve arrangement because the bushing receives a compression spring 16, the other end of which is supported on a valve ball 11 which is in turn held in a valve seat 12.
  • a valve tappet 13 which seals in the valve body 36 is guided in a hole and its upper free end is guided by a guide bush 14, which a has the appropriate stuffing box and O-rings. In this way it is avoided that the high pressure medium from this Guide channel of the valve lifter 13 penetrates to the outside.
  • the upper, free end of the valve lifter 13 sits on a hardened steel insert, the part of the power lever 37 of the Actuating lever 15 is.
  • the operating lever 15 of the Manual shut-off gun 1 consists of a two-part Lever, the one lever is relatively long and as Hand rest 38 is executed.
  • This operating lever as two-armed lever is pivotally mounted in the swivel bearing, and the other lever part is from the aforementioned Power lever 37 formed.
  • This power lever 37 thus cooperates its metal insert on the upper end of the valve lifter 13, which is thus slidable in the axial direction and thus the valve ball 11 lifts from its valve seat 12. So that will the high pressure channel is released and the high pressure medium flows from the interior of the HP hose to the one that is now open Valve seat 12 in the HD channel 30 downstream, the total with 10 designated shutdown device.
  • the kink protection sleeve 2 a toothing 42 at its upper end face, the is designed as a helical internal toothing.
  • Toothing 42 engages a slide 43, one Has actuating button 44 which is fixed to a sliding part 45 is connected, which sliding part has a locking lug 46, which can be brought into engagement with the toothing 42.
  • the slide 43 is spring-loaded in by means of a spring 47 a recess 48 in the housing shell 5 of the Manual shut-off gun 1 held so that the operating button 44 held spring-loaded in its downward position becomes. It is in the region of a recess 49 in the rest Space between the housing shells 5 slidable held.
  • rotation lock is important in the event that a user inadvertently twists the entire assembly, with which there is a risk that the high pressure hose from a Screwing on the manual shut-off gun is unscrewed. If this high pressure hose is then under high pressure medium stands, it can cause serious damage and injuries to lead. This is avoided by said rotation lock, which is only arbitrary by pressing an operating button 44 can be triggered.
