Abstract

The utility model relates to an elastic joint for fluid pipelines, particularly an elastic joint for connecting the pipelines which are used for conveying the fluids of gas, liquid, etc. A flexible rubber pipe has elasticity and integral forming. The both ends of the flexible rubber pipe are respectively sheathed on each fluid convey pipe end to be connected. The middle part of the elastic joint is provided with an unevenness circular corrugation part which causes the elastic joint to bend or twist at any direction in 360 DEG. The pipelines of the both ends of the utility model always keep the fluid to be smooth.

Description

The elastomeric joint that fluid circuit is used

The utility model relates to and a kind ofly uses in the pipeline that connects fluids such as conveying gas or liquid integrally formed elastomeric joint.The two ends of this elastomeric joint are socketed in the end of the FLUID TRANSPORTATION sebific duct that needs connection respectively, and the center section part of joint is arranged with crinkled portion, so that can be in the scopes of 360 degree crooked or reverse to any direction, the pipeline that its two ends are connected can remain unblocked.

The joint of existing various fluid (gas or liquid) pipeline for ease of the connection of pipeline, all uses the pipe joint that hard plastic class material makes and the delivery pipe of its socket then to make with the softer plastics material of material.After both sockets, can cause the phenomenon of sebific duct in the bending of pipe joint socket place.Because the pipe joint of hard material itself can't be crooked, thereby usually cause to flow in the pipeline and have some setbacks or stop up, for example:

1. be used for the gas delivery sebific duct on the acetylene gas welding equipment, be on the copper pipe joint that is socketed on the acetylene gas bucket, the material of pipe joint is hard than sebific duct, and partly make the pipe thread shape at the external diameter of pipe joint, in case socket, just hard outer soft situation in forming is so the softer sebific duct in the outside is easy to lose or puncture.Again, this type of is operated in when carrying out, and often gas cylinder is put upside down on the ground, is very easy to be collided in the working site, and then produces the dangerous phenomenon that gas leaks outside; Perhaps, often, sebific duct is caused pull twisting, also cause sebific duct and pipe joint to come off easily, produce the danger that gas leaks outside because of gas cylinder rolls.

2. more as shown in Figure 1, sebific duct is subjected to the material of bending place in case because of aging damaged, if the inner fluid that holds is a kind of high pressure or dangerous liquid or gas, for example fuel oil, acetylene gas, chlorine ... Deng, then sebific duct will be corroded because of bending at socket place, so that fluid mobile in sebific duct hindered or leak outside, and cause hydrodynamic pressure deficiency in the pipeline, or fluid leaks and produces hazard events such as blast, poisoning, makes working environment and personnel be subjected to serious threat on safety.

So the designer after concentrating one's attention on research for a long time, reaching repeatedly design improved, has proposed elastomeric joint of the present utility model in view of existing various shortcomings in the above various prior art.

The utility model provides a kind of fluid circuit integrated elastomeric joint, its main purpose is when the elastomeric joint that flexible rubber pipe is made is socketed in fluid sebific duct end, its stage casing part is made the crinkled portion that is concavo-convex ring-type, but make this position have the elasticity of free bend, thereby can be widely used in fluid delivery pipeline (the car engine oil pipe for example of various apparatuses, the rain brush pipeline, the outlet of steam turbine car pump, the electrification goods, oil purifier rapid pipe joint, various telescopic pipes, or other are various mechanical, the civil construction class, electric, refrigerating engineering, the gas of chemical industry appliances, the exhaust of aspects such as liquid, the draining delivery line) on.This elastomeric joint can be exempted in the joint bending in the time spent of doing that fluid circuit is subjected to external force or gravity, produced local flattening of pipeline and caused pipeline blockage; Perhaps when pipeline was subjected to long-time complications, this elastomeric joint can prevent material destruction and quick aging, be full of cracks or corrosion breakage, thereby prevents that fluid from leaking, the accidental situation of causing danger.Therefore, it can effectively improve the serviceability of fluid circuit, guarantees the smooth and easy of stream, and safe in utilization.

Below, conjunction with figs. is described in detail specific embodiment of the utility model.In the accompanying drawing:

Fig. 1 is the tectonic maps of the present pipe joint of using always;

Fig. 2 is an embodiment's of the utility model a structural drawing;

Fig. 3 is another an embodiment's of the present utility model structural drawing;

Fig. 4 is one of schematic representation of user mode of the present utility model;

Fig. 5 be user mode of the present utility model schematic representation two;

Fig. 6 be user mode of the present utility model schematic representation three.

As shown in Figure 2, formation of the present utility model comprises:

Elastomeric joint 10 for the flexible flexible rubber pipe of a kind of hollow tubular tool, is made in integrally formed mode, and there is the socket end 11 on the fluid circuit 20 that can be plugged on corresponding big or small caliber at two ends, and the stage casing then is provided with the crinkled part 12 that is concavo-convex ring-type.

Above-mentioned each combination of elements of mat when fluid circuit 20 is subjected to time spent of doing of external force, just can along with bending, make fluid circuit 20 and elastomeric joint 10 not produce the flat phenomenon that contracts at socket place by the flexing action of the crinkled part 12 in elastomeric joint 10 stage casings;

Secondly, as shown in Figure 3, above-mentioned elastomeric joint 10 can be according to factors such as the quantity of fluid circuit 20 and direction, angles, be designed to have several socket ends 11, (for example: straight tube shape, L shaped, T shape or Y shape become an elasticity manifold shape joint, or the pipe joint of other analogous shapes), its socket end is available is threaded or glues together mode such as fixing and other each branch pipe terminal portion is connected to each other.

In sum, the utility model compares with the like product of commonly using, and has following practical effect:

Elastomeric joint of the present utility model can be widely used in various mechanical, On the utensils such as building class, chemical, on the pipe joint of all conveying gas, liquid, Thoroughly to produce body flat because of crooked eliminate fluid pipeline and adaptor cup jointing place for it The phenomenon of contracting keeps fluid circuit unimpeded.

2. the complete pipe that causes because of long-time overflexing of eliminate fluid pipeline Body be full of cracks, burn into are aging or damaged, reach prevent really that stream is obstructed or fluid outside Let out, guarantee the safety of staff and work-yard.

Claims

1. the fluid circuit elastomeric joint of a hollow tubular, it is made by the integrally formed flexible rubber pipe material of rubber-like, its two ends can be respectively and the mutual socket of FLUID TRANSPORTATION pipe end of the big or small caliber of various correspondences, it is characterized in that: be arranged with the crinkled part that is concavo-convex ring-type at the elastomeric joint center section part.
