Embodiment Construction

[0010] Such as figure 1 As shown, the pigging device includes a main pipe 1, a solenoid valve 2, a plastic pipeline 3 and an automatic liquid supply device 4. The pipeline above the main pipe 1 is connected to a plurality of solenoid valves 2, and the inlet of the solenoid valve 2 is connected to the plastic pipeline 3. The plastic pipelines 3 are collected in the automatic liquid supply device 4; the bottom of the main pipe 1 is connected with a plurality of pipeline joints 5, and the pipeline joints 5 are connected to the pre-cleaned steel pipe 7 through the two-way 6 or three-way connection.

[0011] The inner surface of the valve body of the electromagnetic valve 2 is plated with aluminum-silicon alloy.

[0012] The plastic pipeline 3 is made of hard corrosion-resistant plastic.

[0013] The automatic liquid supply device 4 is a kind of automatic infusion device set according to time.

[0014] The specific implementation methods described in the present invention do not ...

Abstract

The invention discloses an automatic pigging device comprising a main pipe, a plurality of solenoid valves, a plastic pipeline and an auto liquid replenishment device. The solenoid valves are connected with the upper pipelines of the main pipe. Inlets of the solenoid valves are connected with the plastic pipelines integrated at the auto liquid replenishment device. A plurality of pipeline joints are connected under the main pipe, and are connected to the steel pipes to be pigged through two-way valves or three-way valves. The automatic pigging device is simple in structure and is capable of selecting flushing liquid according to preset time. The steel pipes are derusted through derusting liquid first, and then the steel pipes are derusted through water in limited time. Thus, the automatic pigging device is efficient and good in effect.

Description

technical field [0001] The invention relates to an automatic pigging device, which belongs to the technical field of machinery. Background technique [0002] The steel pipe is exposed to the air and is easy to rust, both the outer surface and the inner surface of the steel pipe are easy to rust. For industries with high requirements for steel pipes, such as biochemical industry or food industry, before use, the internal and external rust removal potential of steel pipes is very important. must do. Existing derusting method is clumsy, promptly steel pipe is placed in the water tank that derusting liquid is housed, after a period of time, most of rust can be removed. But in this method, the efficiency of rust removal is not high, and there is no washing process, because the water is not flowing, and the effect of rust removal is not good. Contents of the invention [0003] The invention provides an automatic pigging device, which can complete the derusting work of the inne...
