Definitions

  • the present invention relates push-on connectors for connecting pipes without the need of a tool.
  • a push-on connector for connecting cylindrical pipes comprises a body, which is arranged with a cavity which extends through the body between a first end and at least a second end of the connector. At least the first end of the connector is arranged to receive an end of a cylindrical pipe, which means that the connector may be of different kinds like a 2-way straight, a 3-way T-shaped, a 2-way L- shaped, a 4-way connector, or the like. Or the connector may be one or more ends of a valve. The latter may be any kind of valve like for example a control valve, throttle valve, balancing valve, check-valve, 1-way, 2-way, 3-way, 4-way-valve, or the like.
  • the cavity of the push-on connector comprises a first cylindrical portion distal from the first end of the connector, which first portion has a first inner diameter smaller than an outside diameter of a pipe which is to be inserted into the first end of the connector.
  • the first portion of the cavity is in direction towards the first end of the connector followed by a cylindrical second portion with a second inner diameter which is greater than the first inner diameter and which substantially corresponds to an outside diameter of a pipe which are to be inserted into the first end of the connector.
  • the second portion is followed by a cylindrical third portion with a third inner diameter which is greater than the second inner diameter.
  • the third portion is followed by a tapered fourth portion, which tapers radially inwardly in direction towards the first end of the connector and ends in a neck portion.
  • the neck portion has a fourth inner diameter, which is smaller than the third inner diameter of the third portion.
  • the neck portion is followed by a tapered fifth portion which tapers radially outwardly in direction towards the first end of the connector.
  • the push-on connector further comprises a locking sleeve which is axially movably and rotatably arranged at the first end of the connector. This means that the locking sleeve is loosely arranged at the first end such as it is possible rotate (swivel) around a center axis of the first end and further may be moved a distance along the center axis.
  • the locking sleeve comprises an outer collar and a circumferential portion, from which a number of flexible arms extend into the cavity.
  • Each flexible arm ends with a radially inwardly inclined grip portion and the end of each arm further comprises a thick end portion arranged opposite the grip portion.
  • the connector further comprises two sealing rings, which are arranged spaced apart into the third portion of the cavity, and further the connector further comprises at least one support ring, which is arranged into the third portion of the cavity between the sealing rings.
  • the sealing rings and the support ring are arranged as package into the third portion.
  • a transition between the third portion and the second portion of the cavity is arranged as a radially inwardly protruding heel, which functions a stop for the innermost lying sealing ring, wherein a width of the support ring in an axial direction is adapted such as the two sealing rings and the support ring fits between the heel and the tapered fourth portion of the cavity without the sealing rings being compressed radially inwards, transverse the axial direction when not subjected to fluid pressure, wherein an inner diameter of the two sealing rings substantially corresponds with the cylindrical second portion of the cavity.
  • the push-on connector provides a quick, easy and safe assembly where the locking sleeve grips the pipe, for example a copper pipe, automatically when the connector is mounted onto the pipe.
  • the flexible locking arms can flex radially outwards when the pipe is pressed into the coupling.
  • the grip edge at the end of respective flexible arm that protrudes radially from the end of the flexible arms slightly grippes the surface of the pipe and secures the locking sleeve to the pipe in at least a first “attaching state”, when the pipe reaches a final position.
  • the grip edges are further fixed to (cut into) the surface material of the pipe by the narrowing of the cavity at the neck portion. This means, that the grip edges of the locking arms grip harder in the surface of the pipe the more traction or higher liquid pressure, the connector is exposed to at the same time as the sealings expand inwards, towards the pipe, with increased sealing effect.
  • the sealing rings may not expand too much in the axial direction of the cavity/the axial “pipe direction”, since the innermost sealing is more or less clamped between the heel and the support ring, and the outermost sealing is clamped between the support ring and the tapered fourth portion.
  • the sealings may expand but are controlled to expand primarily in the radial direction, by the adaption of the distance between the tapered fourth portion, the heel and the support ring.
  • Prior art solutions do not control the expansion of a sealing in such a controlled way. This is an advantage especially concerning high- pressure applications, which prior art solutions do not provide.
  • the inner diameter of the two sealing rings substantially corresponds with the cylindrical second portion of the cavity. This provides a tight fit around the pipe to which the connector is to be connected to, since both the cylindrical second portion and the sealings of a size of the connector is adapted to the pipe diameter.
  • the push-on connector may further be disassembled by pushing the locking sleeve into the front edge, whereby the grip edges of the flexible arms are detached from the pipe.
  • a transition between the first portion and the second portion of the cavity is arranged as a stop, arranged to stop an axial movement of a pipe when inserted into the connector.
  • the fifth portion of the cavity is followed by a sixth portion with a fifth inner diameter which is greater than the fourth inner diameter of the neck portion.
  • a length of the sixth portion substantially corresponds to a length of the circumferential portion of the locking sleeve.
  • an outer diameter of the circumferential portion of the locking sleeve substantially corresponds with the fifth inner diameter of the sixth portion of the cavity. This is also very important during mounting of the connector to the pipe, for precisely control and guide the connector during the mounting. It is crucial to prevent leakage, why the fitting of the connector to the pipe end must be precise. It is also crucial that the connector is precisely fitted to the pipe if the connector is subjected to outer forces.
  • an inner diameter of the circumferential portion and an inner diameter between opposite flexible arms substantially corresponds with the cylindrical second portion of the cavity.
  • an outer diameter between opposite flexible arms substantially corresponds with the fourth inner diameter of neck portion.
  • the outer diameter between opposite arms i.e., the outer diameter of the “arms portion”, the thickness of the arms and the inner diameter of the neck portion are adapted to allow the arms to fit between the pipe and the neck and also to prevent that the locking sleeve may loosen from the connector.
  • the neck portion comprises an edge which faces the tapered fourth portion.
  • the edge has a sharp design towards the tapered fourth portion which sharp edge is arranged to cooperate with the outer ends of respective flexible arm, which outer end comprises a corresponding sharp protrusion, for interaction with the edge.
  • the body and the locking sleeve is made of metal, preferably brass or stainless steel.
  • metal preferably brass or stainless steel.
  • a valve comprising a connector according to any of the preceding claims.
  • the connector may be one or more ends of a valve.
  • the valve may be any kind of valve like for example a control valve, throttle valve, balancing valve, check-valve, 1-way, 2-way, 3-way, 4-way-valve, or the like.
