Description

Pipeline connecting structure

Technical Field

The utility model relates to the technical field of pipelines, in particular to a pipeline connecting structure.

Background

In the kitchen and toilet field, the drainage of a toilet is generally called sewage, and the drainage of a washroom, a washing machine and a kitchen is called waste water; the drainage of the domestic sewage pipeline is called as a sewage discharge pipe; the drainage of the waste water pipe is called a waste discharge pipe, the pipe for exhausting and maintaining the air pressure balance is an exhaust pipe, and the pipe for discharging rainwater outdoors is called a rainwater pipe and the like. The various sewerage pipes, waste discharge pipes or exhaust pipes between the upstairs and the downstairs are usually communicated with each other, for example, the sewerage pipes in the toilet are usually vertical pipes, and the vertical pipes between the adjacent stories are communicated. The existing drain pipe, waste discharge pipe or exhaust pipe, etc. are usually connected by a joint directly between adjacent pipelines, and the connection mode has the following defects: (1) the pipelines are easy to expand with heat and contract with cold due to temperature change, and if the pipelines are directly connected and fixed, the pipelines are easy to break due to expansion with heat and contraction with cold, or water leakage and air leakage are caused; (2) when adjacent pipelines are connected, the pipelines need to be aligned and installed, so that the installation requirement is high, and time and labor are wasted; (3) the water hammer phenomenon easily occurs, for example, when sewage enters a sewer pipe and falls down along the pipe, the acceleration is increasingly large under the influence of gravity, certain pressure is generated, and the pipeline is broken.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide a pipeline connecting structure which is convenient to install, flexible to adjust and capable of avoiding water hammer.

The technical scheme of the utility model is as follows: a pipeline connecting structure comprises a first pipe section and a second pipe section, wherein a bent pipe is arranged between the first pipe section and the second pipe section.

Further, the elbow is a telescopic elbow.

Further, the bent pipe is a corrugated pipe.

Furthermore, the end parts of the first pipe section and the second pipe section are provided with joints, the two ends of the elbow pipe are provided with elbow joints, and the elbow joints at the two ends are respectively connected with the joints of the first pipe section and the second pipe section.

Furthermore, a fixing piece for limiting the horizontal displacement of the pipe section is arranged on the first pipe section and/or the second pipe section.

Further, the first pipe section and the second pipe section are vertically or horizontally placed.

The utility model has the beneficial effects that: firstly, expansion and contraction can be adjusted: the bent pipe can be used for adjusting the expansion degree between the first pipe section and the second pipe section, namely, the bent pipe is of a bending structure, and when the first pipe section and/or the second pipe section expand and contract, the bent pipe can be used for adjusting, so that the pipe sections are prevented from being broken or damaged due to expansion and contraction; second, the mounting position deviation can be compensated: by arranging the bent pipe, whether the first pipe section and the second pipe section are installed in an aligned mode or not can be not considered; third, water hammer can be avoided: when the flow velocity changes suddenly, the buffer function can be achieved through the bent pipe.

FIG. 1 is a schematic structural view of embodiment 1 of the present invention;

FIG. 2 is a plan view of embodiment 1 shown in FIG. 1.

Detailed Description

The utility model will be described in further detail below with reference to the drawings and specific examples.

Example 1

As shown in fig. 1 and 2: a pipeline connecting structure comprises a first pipe section 1 and a second pipe section 2, wherein an elbow 3 is arranged between the first pipe section 1 and the second pipe section 2.

The scheme has the following advantages: expansion and contraction can be adjusted: the bent pipe can be used for adjusting the expansion degree between the first pipe section and the second pipe section, namely, the bent pipe is of a bending structure, and when the first pipe section and/or the second pipe section expand and contract, the bent pipe can be used for adjusting, so that the pipe sections are prevented from being broken or damaged due to expansion and contraction; the deviation of the installation position can be compensated: by arranging the bent pipe, whether the first pipe section and the second pipe section are installed in an aligned mode or not can be not considered; and thirdly, water hammer can be avoided: when the flow velocity changes suddenly, the buffer function can be achieved through the bent pipe.

In this embodiment, the first pipe section 1 and the second pipe section 2 are both risers. For example: when two sections of sewage vertical pipes in upstairs and downstairs toilets are connected, a bent pipe is arranged between the upper vertical pipe and the lower vertical pipe, wherein the bent pipe is a flexible or elastic bent pipe and can change when the pipe section expands and contracts, so that expansion and contraction of the pipe section are relieved. The radian of the bent pipe can be large or small, and only the expansion caused by heat and contraction caused by cold of the pipe section can be relieved. Preferably, the elbow 3 is a bellows.

In this embodiment, the end portions of the first pipe section 1 and the second pipe section 2 are both provided with joints, the two ends of the elbow are provided with elbow joints, and the elbow joints at the two ends are respectively connected with the joints of the first pipe section 1 and the second pipe section 2. The joint and the elbow joint are both threaded joints, if one is an internal thread, the other is an external thread, the two are fastened through the nut joint 4, namely, one end of the nut joint 4 is the external thread, and the other end of the nut joint is the internal thread, and is respectively in adaptive connection with the joint and the elbow joint.

Example 2

On the basis of embodiment 1, the first pipe section and the second pipe section of this embodiment are further provided with a fixing member for limiting horizontal displacement of the pipe sections, and the fixing member is preferably a limiting bracket capable of limiting lateral movement of the pipe sections.

Example 3

The difference from embodiment 1 is that the first and second tube sections are both cross tubes. For example: when multiple sections of transverse waste water pipelines of a kitchen are connected, bent pipes can be connected between partial adjacent pipe sections. The bent pipe can be positioned above or below the adjacent transverse pipes, and the bent shape of the bent pipe can be omega-shaped, arc-shaped or groove-shaped.

Example 4

The difference from embodiment 1 is that the first pipe section is a vertical pipe, the second pipe section is a horizontal pipe, and when the vertical pipe is connected with the horizontal pipe, a bent pipe is connected between the vertical pipe and the horizontal pipe.

Example 5

The difference from the embodiment 1 is that the connecting ends of the first pipe section 1, the second pipe section 2 and the elbow pipe are all provided with flanges and fixed through threaded connecting pieces.

In summary, the bent pipe of the present invention is mainly used for waste water pipes, sewage pipes, exhaust pipes, and the like in kitchens and bathrooms of houses, office buildings, and the like, and the bent pipe is arranged between pipe sections, so that the pipe sections can be prevented from being damaged due to thermal expansion and cold contraction, such that water leakage, air leakage, and the like can be prevented, and installation position deviation and water hammer can be compensated.
