This application has solved traditional clamp formula connector both sides and has applyed probably to lead to one side not tight problem of sealing when the pretightning force is inhomogeneous, and the leakproofness of this application does not receive the influence that the clamp pretightning force is even or not.

Description

Clamp type sealing pipe joint
Technical Field
The utility model belongs to the pipe connection field especially relates to a clamp formula sealing tube connects.
Background
Nonmetal pipe connection's mode is more, and common flange joint, adhesive bonding, clamp formula are connected etc. have, and flange joint's speed is the slowest wherein, is unfavorable for promoting work efficiency. The reliability of adhesive bonding is poor, and the adhesive is easy to open.
The sealing principle of the existing clamp type connector is that a sealing rubber ring is arranged between a clamp and a pipe fitting, and pretightening force applied to the sealing rubber ring by the clamp is applied to the clamp, so that the sealing rubber ring and two sections of pipe fittings are respectively firmly sealed, namely, two seals exist in the traditional clamp type connector, the pretightening force applied to the two sections of pipe fittings by the clamp is required to be uniform by the two seals, if the pretightening force applied to the two sections of pipe fittings to be connected by the clamp is not uniform, the seal is likely to be not tight, and therefore, in order to further improve the tightness of the clamp type pipe connector, the novel clamp type pipe connector is provided by the application, wherein the tightness is not affected by the uniformity of the pretightening force of the clamp.
SUMMERY OF THE UTILITY MODEL
For solving the inhomogeneous problem that leads to the inconsistent degree of both sides pipe fitting pretension of traditional clamp formula union coupling head pretightning force, the utility model provides a novel clamp formula sealing tube connects, the utility model discloses a leakproofness does not receive the influence that the clamp pretightning force is even whether.
The utility model provides a technical scheme is: a clamp type sealing pipe joint comprises a pipe fitting bell mouth, a pipe fitting socket and a clamp, wherein the pipe fitting socket is inserted into the pipe fitting bell mouth, the inner side of the pipe fitting bell mouth is provided with a horn-shaped flaring, the outer side of the pipe fitting socket is sleeved with a sealing ring with a conical outer contour in a sliding manner, and the conical surface of the sealing ring extends into the flaring of the pipe fitting bell mouth; the pipe fitting bellmouth outside has the right trapezoid recess, and the hypotenuse of right trapezoid recess is close to pipe fitting socket one side, clamp one end inboard have with right trapezoid recess assorted right trapezoid snap ring, the other end inboard of clamp have with the sealing ring support spacing snap ring that leans on.
The further technical scheme is as follows: the sealing ring comprises a conical ring section and a circular ring section, and the circular ring section is abutted against a limiting snap ring of the clamp.
The utility model has the advantages that: according to the invention, the hoop is arranged between the two pipe fittings connected in a socket joint manner, one end of the hoop is clamped in the right trapezoid groove on the outer side of the pipe fitting bellmouth, the other end of the hoop is clamped on the end surface of the sealing ring, so that the radial pre-tightening force of the hoop is converted into the pre-tightening force for pushing the sealing ring to move axially through the inclined surface, the conical section of the sealing ring is plugged between the two pipe fittings to form strong sealing, and the two pipe fittings connected in the socket joint manner are connected in a sealing manner.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a pipe socket; 2. clamping a hoop; 3. a seal ring; 4. a pipe fitting socket; 101. a right trapezoid groove; 102. flaring; 201. a right trapezoid snap ring; 202. a limit snap ring; 301. a tapered ring segment; 302. a circular ring segment.
Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The utility model discloses a pipe fitting bellmouth 1, pipe fitting socket 4 and clamp 2, 4 cartridges of pipe fitting socket in pipe fitting bellmouth 1 to guarantee that the pipeline has fine axiality.
The inner side of the pipe fitting bellmouth 1 is provided with a trumpet-shaped flaring 102, the outer side of the pipe fitting faucet 4 is sleeved with a sealing ring 3 with a conical outer contour in a sliding mode, the conical surface of the sealing ring 3 extends into the flaring 102 of the pipe fitting bellmouth 1, axial pretightening force is applied to the sealing ring 3, and sealing is formed between the two pipe fittings.
The outside of pipe fitting bellmouth 1 has right trapezoid recess 101, and the hypotenuse of right trapezoid recess 101 is close to pipe fitting socket 4 one side, 2 one end inboards of clamp have with right trapezoid recess 101 assorted right trapezoid snap ring 201, the other end inboards of clamp 2 have with sealing ring 3 support spacing snap ring 202 that leans on. When radial pretightening force is applied to the clamp 2, the radial pretightening force is converted into pretightening force for pushing the sealing ring 3 to move axially through the inclined plane, so that the two pipe fittings are connected in a sealing manner, and the sealing performance is not influenced by the uniformity of the pretightening force of the clamp 2 in the sealing process.
In order to further enhance the strength of the sealing ring 3, the sealing ring 3 includes a conical ring section 301 and a circular ring section 302 with an outer diameter larger than the conical ring section 301, and the circular ring section 302 with a larger outer diameter abuts against the limiting snap ring 202 of the clamp 2, so that when a pretightening force is applied, the conical ring section 301 is not easy to deform, a good sealing effect is ensured, if the strength of the sealing ring 3 needs to be further improved, the sealing ring is not easy to deform, and a metal reinforcement can be further arranged in the sealing ring 3.
In summary, the hoop 2 is arranged between two pipe fittings connected in a socket manner, one end of the hoop 2 is clamped in the right trapezoid groove 101 on the outer side of the pipe fitting socket 1, the other end of the hoop 2 is clamped on the end face of the sealing ring 3, so that the radial pre-tightening force of the hoop 2 is converted into the pre-tightening force for pushing the sealing ring 3 to move axially through the inclined plane, the conical ring section 301 of the sealing ring 3 is plugged between the two pipe fittings to form strong sealing, and the two pipe fittings connected in the socket manner are connected in a sealing manner, and the sealing performance of the pipe fitting is not influenced by the uniformity of the pre-tightening force of the hoop 2.
