Description

  • The The invention relates to a connector for pipeline construction for connection a plastic tube with a molding, which connector a basic body with a pipe receptacle for inserting the end portion of a plastic pipe, one serving a jamming of the pipe, on the outer surface of the Pipe supporting clamping bodies and one connected to the body collet as an abutment for the clamp body and one between the inside of the pipe receiving and the lateral surface of a acting in the pipe receiving plastic pipe sealing arrangement includes.
  • in the Pipeline construction is mainly used in the field of drinking water supply, especially in the municipal area often laid plastic pipes. To the Connect or connecting such a plastic pipe to or with a molded part, as another pipe, as a bridge, may be formed as a fitting or the like, wherein the molded parts typically metal parts, are connectors, so-called Plug fittings have been developed with the desired connection without tools can be created. Such connectors have a base body with a cylindrical tube receiving, in which the free end of a plastic tube is used when connected to the connector shall be. The tube holder of the body is usually designed stepped and includes a seen from the direction of the tube from section with a larger diameter and an adjoining, separated by a paragraph section of smaller diameter. The diameter of the smaller diameter section corresponds essentially the outer diameter of the inserted in the recording Tube. The outer section the pipe holder with its larger diameter serves to accommodate a seal arrangement between the tube and the connector. The seal arrangement seals between the lateral surface of the pipe inserted in the pipe receiving and the inner wall of the outer, im Diameter larger section the recording. As a seal is in such a connector typically used a sealing ring. With it scrape or other minor damage on the outside of the pipe used in the pipe receiving the body no Leakage result, sealing rings are used on their Inner protruding in the radial direction one or more sealing lips wear. The basic body is about it in addition, a clamping sleeve associated with each other over the back degree of the basic body extends and has a conically tapered to the pipe section. The collet can on the body molded or a possibly releasably connected to the body Be element. For jamming the inserted into the tube receiving the body End portion of the tube is a commonly trained as a ring Clamp body. The trained as a ring clamp body may be slotted or by incisions in the circumferential direction spaced, the actual clamping body bearing extensions have, which are held on a ring portion. The clamping body is located below the clamping sleeve and supports with its outer lateral surface at the Inside of the clamping sleeve from. Typically feature Clamping rings over a conical clamping portion, pointing at which in the pipe receiving Bottom barbs are formed, which when clamping a tube in the outer surface of the Tube pressed become.
  • used is a plastic pipe in such a connector by this is pushed into the tube holder until the front end of the Pipe at the end of the pipe receiving the body abuts. The insertion of the main body in the pipe receiving the connector runs in the opposite direction for clamping action of the clamp body and is therefore easily possible. To the actually fixing the tube in the connector, the Pipe again slightly be pulled out of the pipe receptacle of the connector, so that then the barbs in the outside penetrate the pipe and the clamping ring with its conical clamping portion in his on the clamping sleeve supporting Clamping position is moved. The same relative movement between the connector and the plastic pipe used in the pipe receiving Also turns on when the connection is put under operating pressure becomes. In the course of such a movement, the pipe is also on the Sealing lip bearing sealing ring moved past. While typically the sealing ring when inserting the tube in the pipe receiving the body is present within the tube intake and thereby in its intended arrangement is held, this can at the above relative movement, which ultimately leads to activation of the clamp body change. In this movement opposite the pipe the connector may begin to roll the sealing ring so that after setting the connector at the end portion of the tube can not be guaranteed with ultimate certainty that the tube is sealed to the connector, in particular if the inserted into the receptacle end portion of the plastic tube is no longer smooth by grooves or the like.
  • Based on such a connector described above, the invention is therefore based on the object, an aforementioned Further develop connectors in such a way that a plastic pipe damaged on the outside by scoring, scratches or the like can be connected sealed in accordance with the intended purpose, without having to fear that the pipe displacements occurring within the pipe receptacle will result in leaks.
  • These The object is achieved by a solved at the beginning connector, wherein the seal assembly a ring body enclosing a tube inserted into the tube receptacle of the main body, in the outer and inner jacket surface each a circumferential sealing ring receptacle is introduced, wherein in the outer sealing ring receptacle a on the inside of the pipe receiving the body abutting first sealing ring and in the inner sealing ring receptacle on the lateral surface of the pipe used in the pipe receiving anlie gender second Sealing ring is inserted.
  • at This connector is the seal assembly for sealed Connect the plastic tube to the connector constructed in several parts and comprises a ring body carrying at least two sealing rings. there is provided that one of the two sealing rings on the inside of the Tube holder of the main body and the other sealing ring on the lateral surface of the pipe receiving to be used or inserted tube. To hold the Seals has the ring body two circumferential sealing ring recordings, which expediently are formed as grooves. In this seal arrangement is each seal either on the outer surface of the in the pipe receiving plastic pipe or on the inside the pipe receiving, so that in a relative movement between Pipe and connector a moment that rolls the sealing ring could lead, if at all only from one area could be induced in the sealing ring. Already for this reason is one possible Rollers counteracted in particular the inner sealing ring. moreover it is by providing the ring body possible, for both Each sealing rings form a chamber in which a sealing ring arranged as intended or is fixed. Also by this measure is effective a roles counteracted the internal seal. Through the ring body is the possibility Thus created that the entire seal assembly with their both sealing rings on their respective surfaces - the inside the pipe holder or the lateral surface of the pipe - according to Art a piston can slide, whereby the ring body without affecting the sealing contact of the respective sealing ring on its surface longitudinally can be moved. A movement of this seal arrangement is thus without disadvantage for the tightness of the connection. Rather, the longitudinal axial Mobility of the seal assembly can be used to the clamping body activate when the seal assembly against the insertion movement the tube is moved. This is for example at a pressurization the connection of the case.
  • In a preferred embodiment, the circumferential sealing ring receptacles of the basic body in longitudinal extension of the connector offset from each other. In this way can the radial Erstrec effect of the seal assembly kept low become. moreover learns thereby this a certain leadership, so that deadlocks or the like are avoided.
  • In the case, that the inner, opposite the lateral surface the plastic tube sealing sealing ring can carry sealing lips be provided, the circumferential sealing ring receptacle of the annular body such train that basically at the first insertion of the plastic tube in the pipe receiving of the connector this sealing ring rolled by a few degrees is, so that the sealing lips initially inclined in the insertion direction of the pipe. In the incoming return movement of the tube is against it Rolling this seal largely prevented or only as far as permitted, that the sealing lips are under prestressing on the outside abut the plastic tube. This can be done, for example be achieved that the expediently formed as a groove circumferential sealing ring receptacle in the longitudinal direction the connector a greater width has as the diameter of the sealing ring. Furthermore, this is Design provided that the sealing ring eccentric in the Sealing ring is arranged and the sealing ring receptacle in the area her to the rear conclusion the connector facing side reducing the height of the sealing ring receptacle having inclined portion. This inclined section acts as Roll brake for the inner sealing ring in the above direction.
  • When clamping bodies can be a multi-segment formed clamping ring with a conical Clamping wedge be provided, the outer surface is itself supported on the inside of the clamping sleeve. Conveniently, has the clamping ring over a backwards under the clamping sleeve Beyond extending Stellfortsatz. The Stellfortsatz serves the Solve the Connector after jamming of the plastic pipe. At the rear end face The Stellfortsatz can be used to solve the Deadlock the readily applied force can be applied around the clamp body with his in the lateral surface of the tube introduced barbs from its jamming bring out.
  • In a further embodiment is vorgese hen, that the clamping body comprises a wrap spring, which has a larger diameter in its tensioned state than in the relaxed state. In the tensioned state, which is secured by a locking device, the tube can be inserted into the wrap spring and into the tube holder. Once the pipe has been inserted into the pipe receptacle, the catch is loosened, so that the wrap spring relaxes with a simultaneous reduction in diameter and thus jams the inserted pipe. The wrap is additionally arranged in an annular clamping wedge, so that when a longitudinal axial stress of the tube by pressurization or by applying a tensile force the wrap is pushed with the clamping ring under the clamping sleeve to increase the clamping pressure.
  • following the invention with reference to an embodiment with reference on the attached Figures described. Show it:
  • 1 a connector with a partially inserted therein plastic pipe in a longitudinal section,
  • 2 : the arrangement of 1 with the tube inserted into its end position into the connector,
  • 3 : the arrangement of 2 after a pressurization,
  • 4 : a further connector in a longitudinal section with a tube inserted therein, but not yet jammed,
  • 5 : the connector of 4 represented without the inserted tube,
  • 6 : a cross section through the arrangement of 4 along the line AB,
  • 7 : the arrangement of 4 with the clamped in the connector tube and
  • 8th : a cross section through the arrangement of 7 along the line CD.
  • A connector 1 serves to connect a plastic pipe 2 a cold water supply line. The connector 1 has a basic body 3 , one in total with the reference numeral 4 marked pipe receptacle is formed. The tube intake 4 has cylindrical inner surfaces and is by providing a paragraph 5 graduated. Therefore, the tube intake includes 4 an inner section 6 with a smaller diameter, the diameter of the section 6 essentially the outer diameter of the plastic tube 2 corresponds, as well as an outer section 7 with a larger inside diameter. The outer section 7 the pipe intake 4 serves to receive a seal arrangement 8th , The seal arrangement 8th includes a ring body 9 with a certain, the longitudinal axis of the connector 1 following extension. The ring body 9 carries an outer, on the inner wall of the outer section 7 the pipe intake 4 adjacent and in a circumferential groove 10 held seal 11 and a second, for engagement with the outer surface of the plastic tube 2 provided, in an inner circumferential groove 12 arranged sealing ring 13 , The sealing ring 13 carries several radially inward to the pipe receiving 4 protruding sealing lips 14 , The groove 12 has one to the rear of the connector 1 or to the mouth of the pipe receiving 4 pointing inclined, the depth of the groove 12 reducing section 15 on. The inclined section 15 extends only slightly under the sealing ring 13 , so that the overall width of the groove 12 greater than the diameter of the sealing ring 13 in that the sealing ring is substantially in the cylindrical portion of the groove 12 is arranged. Thus, the sealing ring lies 13 only with his to the main body 3 and with its to the outer section 7 the pipe intake 4 pointing side to the groove wall. The grooves 10 and 12 are in the longitudinal direction of the connector 1 staggered to each other. The seal 8th can thus be similar to a piston within the outer section 7 the pipe intake 4 in the direction of the longitudinal extension of the connector 1 to be moved.
  • The connector 1 also has a multi-segment clamping ring 16 as a clamping body. The clamping ring 16 has a conical by forming an inclined outer circumferential surface to the rear end of the connector 1 towards tapered Klemmab section 17 on. At the bottom of the clamping section 17 are barbed teeth 18 arranged abragend, which is used to fix the plastic tube 2 in the tube holder 4 of the connector 1 in the lateral surface of the plastic pipe 2 dig. The barbed teeth may, for example, be formed by a coating, such as a corundum coating. Likewise, it is possible to form, instead of the barbed teeth shown in the figures, circumferential, pointing in the insertion direction of the tube, sawtooth-like ribs. In the event that the clamping ring is a plastic part, it may be expedient to provide the pipe facing clamping ribs by using one or more the clamping ribs or individual projections forming inserts made of metal, such as sheet metal part, to provide in the clamping ring or its individual segments , It is then ensured that a proper clipping also takes place in hard PVC pipes as intended.
  • The clamping ring is enclosed 16 from a clamping sleeve 19 attached to the main body 3 is connected for example by a thread or by a throw. The clamping sleeve 19 has a rear end of the terminal connector 1 towards the tapered section on the clamping section 17 of the clamping ring 16 serves as an abutment to the desired deadlock with the plastic pipe 2 to be able to bring about.
  • Molded on the clamping section 17 of the clamping ring 16 is a Stellfortsatz 20 , the back under the clamping sleeve 19 led out. The Stellfortsatz 20 or its free end edge 21 Serve as a tool to after the jamming of the plastic pipe 2 in the tube holder 4 of the connector 1 to be able to cancel the clamping action, for example by the Stellfortsatz 20 to the main body 3 of the connector 1 is taken. The Stellfortsatz 20 is designed as a ring body, which is the individual segments of the clamping ring 16 wearing.
  • The clamping ring 16 with its segments is in the longitudinal axial direction by compression springs with the ring body 9 the seal arrangement 8th connected. As springs plastic springs, for example, so-called omega feathers or separate metal springs can be used. In such an embodiment, the seal assembly 8th or the ring body 9 the same with relaxed springs of the clamping ring 16 spaced. In the event that the aforementioned elements are arranged in the longitudinal axial direction resiliently to one another, it is expedient, on the annular body 9 the seal arrangement 8th to the clamping ring 16 protruding and on the clamping ring 16 or its segments in an aligned arrangement to the ring body 9 to arrange protruding adjusting tabs. These serve the purpose that during a movement of the seal assembly 8th within the tube intake 4 against the insertion of the tube 2 the clamping ring 16 in its clamping position under the clamping sleeve 19 is pushed. Thus, in principle, the seal arrangement 8th be used as an actuator for activating the clamp body. Basically, both elements - ring body 9 the seal arrangement 8th and clamping ring 16 - Together with the molded Stellfortsatz 20 also train an objective unit.
  • The above-described activation of the clamping body results from the fact that by providing two different sealing rings between the outer sealing ring 11 and the inside of the tube holder 4 another and above all a lower friction can be defined than between the inner sealing ring 13 and the lateral surface of the plastic tube. In a relative movement of the plastic tube 2 to the connector 1 For example, when applying a Zugspannweg the seal assembly is moved together with the tube, so that by this movement of the clamping ring 16 in his the pipe 2 holding clamping position is brought.
  • In the clamping sleeve 19 are distributed circumferentially several openings 22 brought in. These openings 22 can serve as tool receiving openings, in the event that the clamping sleeve 9 in contrast to the embodiment shown in the figures with the main body 3 is screwed. Basically, the openings 22 also serve the purpose of the current position of the clamping ring 16 below the clamping sleeve 19 capture.
  • To jam the pipe 2 in the tube holder 4 of the connector 1 This is first completely in the tube recording 4 introduced, like this one in 2 is recognizable. When inserting the plastic tube 2 this will be on the sealing lips 14 of the sealing ring 13 moved past and the seal assembly 8th if not in your in 1 shown position, to the paragraph 5 the pipe intake 4 moved up. When pressure is applied to the connector 1 connected end portion of the plastic tube 2 becomes the plastic pipe 2 contrary to its original insertion movement from the pipe holder 4 - as in 3 shown - slightly pushed out. During this movement, the clamping ring 16 due to its support on the clamping sleeve 19 on the outer surface of the plastic pipe 2 wedged and the barbed teeth 18 in the lateral surface of the plastic pipe 2 pressed. In this relative movement of the plastic tube 2 opposite the connector 1 also becomes the seal arrangement 8th moved in the same direction piston-like, but without the risk that the sealing ring 13 in this movement rolls, so in the in 3 shown arrangement, the plastic tube 2 still sealed to the connector 1 connected. Rather, by the above-described movement of the seal assembly 8th and the contacting of the adjusting tabs of the annular body 9 with those of the clamping ring 16 the clamping ring 16 pressed into its Verklemmposition.
  • 4 shows another connector 23 , which is basically constructed like the connector 1 of the 1 to 3 , The connector 23 is different from the connector 1 only by the formation of its clamping body 24 , The clamp body 24 includes a wrap spring 25 in the tensioned state (cf. 4 ) has a larger winding diameter than in the relaxed state. In the illustrated embodiment, the wrap is for this purpose 25 turned with one-sided fixed end at the free end and held in this tense state. Held the wrap is 25 in its tensioned state by a mounting aid as a locking device, which is removed to relax the wrap. In the tensioned state is in the pipe receiving 26 (see. 5 ) of the connector 23 a plastic tube 27 pushed in until the in 4 shown position is reached. To jam the pipe 27 in the tube holder 26 of the connector 23 becomes the wrap 25 by removing the mounting aid, which may be a locking pin or a fuse clip, brought to relaxation. In the course of this relaxation, the inner diameter of the wrap spring decreases 25 , which puts it in the loop 25 inserted tube 27 is jammed. The wrap 25 in turn is supported by a ring body having a clamping bevel 28 on the inside of a clamping sleeve 29 to the desired clamping pressure on the in the pipe receiving 26 inserted tube 27 to reinforce. The wrap 25 is together with her ring body 28 longitudinal axial movable, as well as to the 1 - 3 described clamping ring 16 of the connector 1 , This is also the case with the connector 23 the wrap spring 25 with her ring body 28 in its Verklemmposition under the clamping sleeve 29 brought when the pipe 27 is moved longitudinally axially against its insertion movement - either by pressurizing the connection by pressing or by applying a tensile force. The wrap 25 serves in this case, in particular for clamping the annular body serving as a clamping ring 28 , with the pipe 27 , That in the connector 23 jammed pipe is in 7 shown. A comparison of 4 and 7 makes it clear that between the cocked and the relaxed position of the wrap 25 this towards the rear end of the connector 23 down under the clamping sleeve 29 has been moved.
