CN202266828U - Asphalt pipeline system - Google Patents

Abstract

The utility model discloses an asphalt pipeline system, which comprises an asphalt tank communicated with an oil barrel through an output pipe. An extensible device is a bent pipeline arranged at the middle position of the output pipe. By means of the technical scheme, the asphalt pipeline system has the advantage that the bent pipeline arranged on the pipeline can buffer impact caused by stress and tension generated by inconsistence of expansion and contraction on valves so that damage rate of the valves is reduced. In addition, the bent pipeline can be arranged by using an original pipe in the middle of the pipeline only, thereby greatly saving cost.

Description

The pitch pipe-line system

Technical field

The utility model belongs to chemical industry equipment, relates to a kind of pipe-line system specifically.

Background technique

In chemical enterprise, the streams of each inter process goes out inflow and all need realize through pipeline.Common UNICOM one pipeline between asphalt tank and Asphalt tank, pipeline is provided with valve, and the temperature of charge in the pipeline has the phenomenon of expanding with heat and contract with cold when high; Pipeline is different with the degree of expanding with heat and contract with cold of valve like this, usually can damage valve, needs to change; If being set, intumescent sheet can solve this type of problem generation on pipeline; But the intumescent sheet cost is higher, does not generally adopt, but directly changes valve.

Summary of the invention

The purpose of the utility model just is to overcome above-mentioned deficiency provides a kind of cost little pitch pipe-line system.

The technological scheme of the utility model is:

A kind of pitch pipe-line system, asphalt tank, asphalt tank is communicated with oil drum through output tube, and output tube is provided with expansion device.

Above-mentioned pitch pipe-line system, said expansion device is arranged on the neutral position of output tube.

Above-mentioned pitch pipe-line system, said expansion device are that crooked pipeline is set on output tube.

Adopt technique scheme; The utility model has following advantage: because pipeline is provided with crooked pipeline; Crooked pipeline plays buffering because of inconsistent stress that produces and the tension force impact to valve of expanding with heat and contract with cold; Thereby reduce the spoilage of valve, and crooked pipeline is set only need in the middle of pipeline, just can realizes, practiced thrift cost greatly with original pipe.

Description of drawings

Fig. 1 is the structural representation of the present pitch pipe-line system of using always;

Fig. 2 is the utility model structural representation.

Embodiment

A kind of pitch pipe-line system as shown in Figure 2, asphalt tank 1, asphalt tank 1 is communicated with oil drum 3 through output tube 2, and output tube is provided with valve 4, and output tube 2 is provided with expansion device 5, and said expansion device is that crooked pipeline is set on output tube.

The preferred structure of the utility model is the neutral position that expansion device is arranged on output tube between valve 4 and the asphalt tank 1.

Claims (3)

1. pitch pipe-line system, asphalt tank, asphalt tank is communicated with oil drum through output tube, and it is characterized in that: output tube is provided with expansion device.

2. pitch pipe-line system according to claim 1 is characterized in that: said expansion device is arranged on the neutral position of output tube.

3. pitch pipe-line system according to claim 2 is characterized in that: said expansion device is that crooked pipeline is set on output tube.
