Abstract

The utility model discloses an electric heating oil tube. The tube comprises a tube body, wherein diversion grooves are evenly distributed on the inner circumferential wall of a liquid outlet of the tube body at intervals along the axial direction of the liquid outlet, cross sections of diversion grooves are triangular, the outer circumferential surface of the tube body is sleeved by a mineral wool insulating layer which is 5-10cm thick, and an electric heating strip is arranged between the mineral wool insulating layer and the outer circumferential surface of the tube body. By the aid of the electric heating oil tube, flow of liquid such as petroleum in the oil tube can be effectively guaranteed, and normal production can be guaranteed even in winter.

Description

The electric heating oil pipe

Technical field

The utility model relates to a kind of electric heating oil pipe.

Background technique

In the winter of northern China, the oil pipe that uses in the field produces only depends on the installation thermal insulation layer, often can not guarantee the proper flow of fluids such as the interior oil of oil pipe effectively, and influence is produced and carried out.For this reason, the someone has developed the thermal insulation tubing that the ribbon heater is installed, though can improve the serviceability temperature in winter of oil pipe to a certain extent, the ribbon heater is arranged reasonable inadequately, has also caused the big problem of power consumption.

Summary of the invention

The purpose of the utility model is to provide a kind of electric heating oil pipe, and the contradiction of can balanced power consumption low and high insulating effect guarantees that oil pipe normally uses winter, reduces the field produces cost.

The purpose of the utility model is to realize like this; A kind of electric heating oil pipe comprises body, and it axially is uniformly distributed with the liquid outlet inner circle wall upper edge of body guiding gutter is being set at interval; The guiding gutter cross section is triangular in shape; Suit the mineral cotton thermal insulation layer on the outer circumferential face of body, and the thickness of mineral cotton thermal insulation layer is 5-10cm, between mineral cotton thermal insulation layer and the body outer circumferential face heat tape is being set.

The utility model guarantees that the liquid speed of oil pipe joint does not reduce, through heat tape is set through guiding gutter is set; And the mineral cotton thermal insulation layer is set; Effectively improve heating, the heat insulation effect of oil pipe, reduce heat loss greatly, the contradiction of can balanced power consumption low and high insulating effect; Guarantee that oil pipe normally uses winter, reduce the field produces cost.

Description of drawings

To combine accompanying drawing that the utility model is done further detailed explanation below.

Fig. 1 is the perspective view of the utility model.

Embodiment

A kind of electric heating oil pipe; As shown in Figure 1, comprise body 3, it axially is uniformly distributed with the liquid outlet inner circle wall upper edge of body 3 guiding gutter 4 is being set at interval; The guiding gutter cross section is triangular in shape; Suit mineral cotton thermal insulation layer 1 on the outer circumferential face of body, and the thickness of mineral cotton thermal insulation layer 1 is 5-10cm, between mineral cotton thermal insulation layer 1 and the body outer circumferential face heat tape 2 is being set.On the body outer circumferential face, heat tape 2 is connecting temperature controller and power supply to heat tape 2 uniformly at intervals, and the spacing between the heat tape 2 is 10-20cm, and heat tape 2 spacings are arranged rationally, so that reduce power consumption.

Heat tape 2 can adopt self temperature control heating tape, and it adopts the conductive core band with " PTC " characteristic and is capped the insulation sheath forms, can be along with being regulated output power automatically and mix hot temperature by the temperature variation of companion's heat target; Also arbitrarily brachymemma or within the specific limits spreading use, have good insulation performance performance, aging quality resistance, low pressure operation, safe and reliable, advantage such as ductility good, be convenient to install, working service is convenient.The utility model can be guaranteed the flowing of liquid such as oil in the oil pipe effectively, normally carries out even also can guarantee in the winter time to produce.

Claims
