Problems solved by technology

Due to the material difference between plastic and steel, plastic has a large expansion coefficient. After a period of time, the pre-tightening force will fail, resulting in air leakage due to poor sealing. Therefore, it is necessary to tighten the bolts frequently.
This kind of structure contains many steel parts, is heavy, and is inconvenient to carry, which increases the complexity of construction.

Embodiment approach 1

[0009] Embodiment one of the present invention is the water-gathering well that permafrost is used, and it is made up of well body, pumping stem. The well body is a hollow four-way structure, and the well body is welded by the end cap 1 at the bottom, the pipe section 2, the cross section 3 in the middle, the side wall pipe section 4 on both sides, and the top well cover 5. The well cover 5 has reserved nozzles 6, 17 that communicate with the well body. The pumping stalk is made up of water pumping rod 15 and the water return rod next to it. The water pumping rod 15 is inserted in the reserved nozzle 17 of the well cover 5, and the outside is connected with an electric heating variable diameter 16, an electric heating tee 14, a steel-plastic conversion 13, and a copper valve 12 to form. The return pipe is composed of 90-degree electric melting elbow 11, steel-plastic conversion 10, copper valve 9, steel-plastic conversion 8, electric melting sleeve 7, and electric heating sle...

Embodiment approach 2

[0012] Embodiment 2 of the present invention is a water-collecting well for non-frozen ground, which does not contain a return pipe and is composed of a well body and a pumping stem. The well body is a hollow four-way structure, which is specifically welded by the end cap 1 at the bottom, the pipe section 2, the cross section 3 in the middle, the side wall pipe sections 4 on both sides, and the well cover 18 at the top. The top of the well cover 18 has a reserved nozzle 17 that communicates with the well body, and a nozzle 20 that does not communicate with the well body. The pumping stem 15 is inserted in the reserved nozzle 17 of the well cover 18, and the outside is connected with an electric-melt variable diameter 16, an electric-melt pipe fitting 19, a steel-plastic conversion 13, and a copper valve 12 to form.

[0013] The condensed water in the gas is collected to the bottom of the water collecting well through the pipeline, and after a period of time, the accumulated wa...

Abstract

The present invention is one liquid eliminating device for fuel gas pipeline. The integral water trap is one welded assembly comprising trap body and water pump, the trap body is one hollow four-wag structure comprising end cap, pipe section, four water pipe, side wall section and trap cover; and the water pump consists of welded pipe units, several steel-plastic converting ports and valve. The trap body and the water pump may be separated for easy transportation, and the welded part has no leakage. Being safe and reliable, the present invention can meet the requirement of fuel gas polyethylene pipeline.

Description

technical field [0001] The invention belongs to a device for separating and removing liquid in a gas pipeline network Background technique [0002] The water collecting well used in the construction of the existing polyethylene gas pipeline network is a combination of steel structure and polyethylene. A flanged connection is adopted between the water well part and the pumping stem. The wellhead is connected with a plastic flange sleeve steel flange and another steel flange piece, and the middle is fastened by bolts. Due to the material difference between plastic and steel, plastic has a large expansion coefficient. After a period of time, the pre-tightening force will fail, resulting in air leakage due to poor sealing. Therefore, bolts need to be tightened frequently. This kind of structure contains many steel parts, is heavy, and is inconvenient to carry, which increases the complexity of construction. Contents of the invention [0003] The purpose of the present invent...
