Description

Quick connector for preventing vortex formation for corrugated pipe connection

Technical Field

The utility model relates to the field of machinary, concretely relates to quick-operation joint that bellows joint formed with preventing vortex.

Background

The metal corrugated pipe is a flexible pressure-resistant pipe fitting, is arranged in a liquid conveying system, is used for compensating the mutual displacement of a pipeline or a machine and equipment connecting end, absorbs vibration energy, can play roles of vibration reduction, noise reduction and the like, and has the characteristics of good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance and the like. The small-caliber metal corrugated pipe is generally connected by adopting a quick connector, the inner cavity of the conventional quick connector is a straight inner cavity, the rubber ring sleeved outside the corrugated pipe is directly sleeved at two ends of the inner cavity of the quick connector, the inner cavity of the rubber ring is communicated with the inner cavity of the quick connector, but the inner diameter of the rubber ring is smaller than that of the quick connector, so that when liquid such as water flows through the inner cavity of the quick connector from the rubber ring at one end of the quick connector and then flows through the rubber ring at the other end of the quick connector, a vortex is formed between the two rubber rings, along with the increase of water flow speed, the larger the vortex impact force is, the vortex formed here impacts the rubber ring at the other end for a long time, the rubber ring is quick to age in the using process, short in service life, easy to leak water, the rubber.

SUMMERY OF THE UTILITY MODEL

The technical problem solved by the utility model is that the inner chamber of present quick-operation joint is straight inner chamber, and position between two rubber rings forms the swirl, and rubber ring use is ageing fast, short-lived, easily leak, often need change the rubber ring, provides a simple structure, practicality, leak protection water bellows connection with preventing vortex formation's quick-operation joint.

In order to solve the technical problem, the utility model adopts the following technical scheme: a quick connector formed by vortex prevention for connecting a corrugated pipe comprises the corrugated pipe and a connector body, wherein a copper ring and a connecting nut are sleeved on the outer side of the corrugated pipe, the copper ring is arranged in the connecting nut, and the connecting nut is in threaded connection with the connector body; the connector comprises a connector body and is characterized in that rubber rings are sleeved at two ends of the connector body, a convex ring is arranged on the inner wall of the connector body, two ends of the convex ring are connected with the rubber rings, the inner cavity of the convex ring is communicated with the inner cavity of the rubber rings, and the inner diameter of the convex ring is equal to that of the rubber rings.

The end part of the corrugated pipe extends into the rubber ring, and the outer side of the rubber ring is in contact with the copper ring.

The copper ring comprises two half rings, a clamping groove is formed in the inner wall of the copper ring, a retaining ring is arranged on the outer wall of the copper ring, annular grooves are formed in two sides of the retaining ring, and a sealing ring is arranged in cooperation with the annular grooves.

The convex ring and the joint body are of an integrally formed structure.

The utility model discloses at this internal bulge loop that sets up of joint for after the rubber ring installation, connect this internal warp and rubber ring internal warp the same, can not make the flow cross section of rivers change, make rivers flow gently at connecting this internal, effectively prevent the formation of swirl, prevent to produce big impact force to the rubber ring, the damage of less rubber ring, the life of greatly increased rubber ring.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model comprises a corrugated pipe 1 and a joint body 2, wherein a copper ring 3 and a connecting nut 4 are sleeved outside the corrugated pipe 1, the copper ring 3 is arranged in the connecting nut 4, and the connecting nut 4 is in threaded connection with the joint body 2; connect 2 both ends cover of body and be equipped with rubber ring 5, be equipped with bulge loop 21 on the inner wall of connecting body 2, bulge loop 21 both ends are connected with rubber ring 5, the inner chamber of bulge loop 21 is linked together with the inner chamber of rubber ring 5, the internal diameter of bulge loop 21 equals the internal diameter of rubber ring 5. The inner cavity of the water flow right convex ring is ensured to stably flow into the inner cavity of the rubber ring 5, the flow rate is inconvenient, the cross-sectional area is inconvenient, the formation of vortex is prevented, and the impact force on the rubber ring is prevented from being overlarge.

The end part of the corrugated pipe 1 extends into the rubber ring 5, and the outer side of the rubber ring 5 is in contact with the copper ring 3. The rubber ring 5 is in interference fit with the copper ring 3, and plays a role in fixing and sealing the corrugated pipe.
