Detailed Description

The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model provides an anti-freezing pipe with a connecting piece as shown in figures 1-5, which comprises an inner pipe 1, a heating device, a reinforcing layer 2, a heat-insulating layer 3 and a protective layer 4; the heating device comprises a temperature sensor and a heating element 5 which are arranged in the inner tube 1, and a temperature controller, wherein the temperature controller is in signal connection with the temperature sensor and the heating element 5; the inner pipe 1 both ends all are provided with connecting piece 11, enhancement layer 2, heat preservation 3 and inoxidizing coating 4 set gradually from inside to outside on the 1 surface of inner pipe.

The inner tube can adopt stainless steel pipeline, as the base tube of the utility model, the liquid medium flows with its direct contact and in its inside. The heating device comprises a temperature sensor, a heating element and a temperature controller. Temperature sensor and heating member all set up on the inner tube outer wall to should keep the safe distance of mutual noninterference between the two, minimize the interference that the heating member caused the testing result. The temperature sensor is used for monitoring the real-time temperature of the liquid medium transmitted to the outer surface of the inner pipe, is in signal connection with the temperature controller, converts the temperature into an electric signal and then transmits the electric signal to the temperature controller. The heating element is used for heating the inner pipe, so that the temperature of the inner pipe is increased, heat is transferred to the liquid medium, and the phenomenon that the liquidity is poor due to the fact that the temperature of the liquid medium is too low is avoided; the heating element can adopt electric heating wires or electric heating films and other electric heating equipment, and covers the whole outer surface of the inner pipe as much as possible, so that the inner pipe is heated uniformly. The temperature controller can adopt an S7-200 type programmable controller, utilizes the existing PID temperature control technology, controls the on-off of the heating element according to the temperature electric signal detected by the temperature sensor, specifically, can set a temperature limit according to the fluidity requirement of the liquid medium, and when the temperature detected by the temperature sensor is lower than the temperature limit, the temperature controller opens the heating element to heat the inner tube.

The inner tube both ends all are provided with the connecting piece, are convenient for and other pipeline or equipment connection. And a reinforcing layer, a heat preservation layer and a protective layer are further arranged on the inner pipe between the two connecting pieces. The reinforcing layer may be made of glass fiber reinforced material and may be covered with available filament winding process to raise the structural strength and rigidity of the inner pipe and protect the heating parts from damage. The heat preservation sets up on the enhancement layer surface, covers whole body for reduce inside and external heat exchange efficiency, slow down calorific loss, can adopt thermal insulation material such as foam rubber goods or glass fibre insulation cotton. The general intensity of the material that the heat preservation was used always is not enough, and the complex environment that the pipeline was located causes the damage to the heat preservation easily, reduces the heat preservation effect, consequently, outside the heat preservation, still is provided with the inoxidizing coating.
