Abstract
The utility model relates to a connecter for high pressure liquid transfusion pipes. The utility model is mainly composed of a pipe joint, a screw cap, a pressure ring, a sealing ring and a locking ring. An inner wall of the screw cap with holes is provided with the truncated conical locking ring with an opening; perforated screw cap is provided with an internal opening of the, the inner slope of the screw cap is matched with the outer slope of the locking ring; a convex edge of the locking ring is clamped on the concave table position of the inner wall of the screw cap; discontinuous type convex ribs are arranged along the inner wall of the locking ring in a radial direction; the pressure ring is arranged at the position attached at the locking ring; the pressure ring is tightly abutted with the pipe joint; the slopes of the pressure ring and the pipe joint form inverted V-shaped space in which the sealing ring is arranged. The utility model has good effects of fixing and sealing, and has no cracking and leakage phenomena for 24 hours proved by a hydraulic test of 1.6MPa after products are assembled.
Description
The utility model relates to a kind of connection set of high-pressure transfusion tube line, particularly the plastics coupling arrangement.
The connection set such as the pipe of existing transfer line connects, threeway, elbow etc. have metal, plastic tube fitting respectively, the plastic tube fitting normally installs seal ring additional at the spiral cover place that pipe connects and screws, because pipe fitting will take place and move, reveals in seal ring displacement distortion when spinning when the pipe internal pressure reaches 0.3～0.4mpa." No. 94236424.4; respectively be called " leak-tight seal locking element and quick connection pipe fitting thereof " patent and on existing pipe connector basis, make improvements; the sealing locking element is a ring, at this ring bodies inwall protruding structure is set, and places locking nut and mouth of pipe screw thread to spin this locking element.This structure only depends on locking nut and locking element sealed pipe to connect owing to elastic sealing structure is not set, and the force bearing point of protruding structure is few simultaneously, unbalance stress, and when the hardness increase that connects material owing to be suitable for that high pressure infuser needs of pipeline and pipe, the fit sealing effect is relatively poor.
The purpose of this utility model is to overcome the defective that existence is put in aforementioned tube tipping, and a kind of rational in infrastructure, high-pressure transfusion tube connector that the fastening effect of sealing is better than the aforementioned tube fitting greatly is provided.
The utility model mainly by pipe connect, blind nut, pressure ring, seal ring and locking ring form, characteristics are to have increased elastic sealing structure, and improved the structure of locking ring, specific structural features is: at blind nut inwall with holes truncated cone type locking ring is housed, is axially arranged with an opening along it, the interior inclined-plane of blind nut matches with the outer inclined-plane of locking ring, when the turn blind nut, interact with the truncated cone inclined-plane, make locking ring expansion or contraction, tubing is locked.The convex edge of locking ring is stuck in the concave station place of blind nut inwall, along the inwall radial arrangement of locking ring incontinuous protruding rib is arranged, so that pipe fitting is tightened.Place pressure ring near the locking ring place, each have an inclined-plane at interface tube and near the pressure ring at the pipe place of connecing, and constitute in its joint
Type space, seal ring place in this space.Rely on pipe to connect the inclined-plane and the inclined-plane of pressure ring own of end during the pressure ring pressurized, internal diameter of the seal ring is compressed little, play the fastening effect of sealing.During installation blind nut, locking ring, pressure ring, seal ring are sleeved on the tubing successively, then the tubing insertion tube are connect in the main hole, the rotation blind nut can compress sealing.
In order to simplify the making of moulds of industrial equipment, can satisfy different pipe fitting needs, pipe connects in the blind nut of the other end can be provided with shutoff, and shutoff and pipe connect and each have an inclined-plane, and constitute in its joint
Type space, seal ring place in this space, and this structure replaces elbow.
The utility model is compared with existing pipe connection has following advantage:
1, rational in infrastructure, seal fastening effectively, carry out hydraulic pressure test 1.6mpa after the product assembling and keep 24 hours crack-free seepage phenomenons;
2, preparation process is simple, and this structure can satisfy the design needs of multiple pipe connector, is suitable for using in the every profession and trade highly pressurised liquid delivery line.
Doing one below by accompanying drawing in conjunction with mode of execution of the present utility model describes.
Fig. 1 is a structure sectional view of the present utility model.
Fig. 2, Fig. 3 are respectively the topology view of locking ring and along the sectional view of opening.
Fig. 4 is the structural representation of seal ring.
Referring to Fig. 1, Fig. 2, at blind nut with holes 4 inwalls truncated cone type locking ring 1 is housed, and be axially arranged with an opening 8 along it, the interior inclined-plane of blind nut 4 matches with the outer inclined-plane of locking ring 1, and the convex edge of locking ring 1 is stuck in the concave station place of blind nut inwall, along locking ring 1 inwall radial arrangement incontinuous protruding rib 7 is arranged, can be provided with 1～8 layer according to caliber size salient rib, with suitable increase locking area, in the path connector locking ring 2～3 layers of fin can be set usually, big footpath connector can be provided with 4～6 layers.See Fig. 3, in order to increase the locking intensity of salient rib, for being staggered, the inclination angle of every section salient rib is 30 °～45 ° between every layer of salient rib 7, make a plurality of be evenly distributed have the tilt angle between the section hangnail, the blind nut inner tubal wall is tightened.The material of locking ring 1 can be selected intensity and hardness height for use, and has certain flexible ABS plastic.Place pressure ring 2 near locking ring 1 place, connect 5 mouthfuls and connect 5 pressure ring 2 near pipe and each have an inclined-plane, and constitute in the joint that pipe connects with pressure ring at pipe
The type space, seal ring 3 places in this space.See Fig. 4, seal ring 3 can carry different liquid to change according to pipeline, as conventional seals cushion rubber, corrosion-resistant, withstand voltage, oil-resistant seal ring.
Pipe connects in the blind nut 4 of 5 the other ends can be provided with shutoff 6, and shutoff 6 connects 5 with pipe and each has an inclined-plane, and constitutes in its joint
Type space, seal ring 3 place in this space, and this structure is applicable to elbow.
