Abstract

The utility model discloses a pipeline connection structure. The pipeline connection structure comprises a flow guide hole, wherein the flow guide hole is formed in mutually connected workpieces, an adapting pipe is arranged in the flow guide pipe, the adapting pipe penetrates thorough a joint of the workpieces, flowing channels of each workpiece are enabled to be communicated, an inlet end of the adapting pipe is connected with an external connection pipeline, the adapting pipe is in interference fit with the workpieces so that the adapting pipe is tightly connected with the workpieces, and the external connection pipeline extends into the adapting pipe to be tightly joint with the inner wall of the adapting pipe. The pipeline connection structure enables the flowing channels in the mutually welded or bonded workpieces to be mutually communicated by means of the adapting pipe, can effectively prevent fluid from leaking in the joint position of the workpieces, and prevents machining chips in the common borders from being carried into equipment.

Description

A kind of pipeline jointing construction

Technical field

The utility model relates to pipeline, relates in particular to a kind of pipeline jointing construction that prevents fluid leakage.

Background technique

In the connection of pipeline, the runner that often runs into fluid need to be through the situation of interconnective workpiece, if two workpiece incomplete welding or bonding situation may occur for welding or bonding together, can produce leakage when fluid is by the workpiece joint this moment; Two workpiece welding or when bonding together, the junction plane place has larger slit sometimes, when processing flow channel, understanding some processing bits enters in the slit of junction plane, when fluid passes through runner, part processing bits can be brought in the equipment, equipment is caused damage.

The model utility content

The purpose of this utility model provides a kind of pipeline jointing construction, brings equipment into and causes damage to avoid fluid leakage and fluid will process bits.

The utility model is that the technological scheme that its technical problem of solution adopts is,

A kind of pipeline jointing construction includes pod apertures, and this pod apertures is formed in the workpiece that engages one another, be provided with transfer tube in the described pod apertures, this transfer tube runs through the junction point of workpiece, and the runner in each workpiece is communicated with, and the entry end of transfer tube links to each other with external pipe;

Particularly, be interference fit between described transfer tube and the workpiece, the end welding makes transfer tube closely be connected with workpiece; Described external pipe stretches into transfer tube inside, with the inwall fluid-tight engagement of transfer tube.

The utility model has the advantage of, this pipeline jointing construction utilizes transfer tube that runner is communicated with between mutual welding or bonding workpiece, can prevent effectively that fluid from leaking at the intersection of workpiece, and avoids the processing of intersection to consider to be worth doing and brought in the equipment by fluid.

Description of drawings

Fig. 1 is the schematic diagram of the pipeline jointing construction that the utility model proposes.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.

As shown in Figure 1, the pipeline jointing construction that the utility model proposes includes pod apertures 1, pod apertures 1 is formed in the workpiece 2 and 3 that engages one another, workpiece 2 adopts the mode of welding to connect with being connected, and its intersection has the slit, is provided with transfer tube 4 in the pod apertures 1, transfer tube 4 runs through the junction point of workpiece 2 and 3, and with the welding of workpiece 2 and 3 ends, the runner in workpiece 2 and 3 is communicated with, the entry end of transfer tube 4 links to each other with external pipe 5; Be interference fit between transfer tube 4 and workpiece 2 and 3, transfer tube 4 closely is connected with being connected with workpiece 2; External pipe 5 stretches into the inside of transfer tube 4, with the inwall fluid-tight engagement of transfer tube 4; This pipeline jointing construction utilizes transfer tube that runner is communicated with between mutual welding or bonding workpiece, can prevent effectively that fluid from leaking at the intersection of workpiece, and avoids the processing of intersection to consider to be worth doing and brought in the equipment by fluid.

The pipeline jointing construction of this anti-leak, anti-processing bits access arrangement, to utilize a joint to be connected on two workpiece, each workpiece all some joint is connected with it, forms bridge arrangement, makes runner avoid the seam crossing of workpiece, be interference fit between joint and two workpiece, to prevent that joint from coming off from workpiece, prevent simultaneously fluid from the leakage of the slit between joint and workpiece, other pipeline that connects workpiece is directly connected on the joint, form complete runner, satisfy the Fluid Flow in A needs.

Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
