Description

Technical Field

[0001] The utility model relates to a multifunctional water pumping cap structure for a gas condensate water collecting well, belonging to the technical field of gas water collecting wells. Background Art

[0002] At present, the collection method of condensate from domestic gas pipelines is mostly in the form of cement structure collection wells. The gas collection wells need to ensure the normal circulation of internal gas with the outside world. Therefore, a pumping hole is opened on the top of the gas collection well to release toxic and harmful gases such as carbon monoxide and hydrogen sulfide volatilized from the gas condensate in the collection well.

[0003] Since most of the collection wells are set up in open air and the pumping holes of the collection wells are exposed, rainwater and garbage may enter the collection wells, causing the condensation water level in the collection wells to rise and the gas condensation water to overflow, resulting in environmental pollution. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a multifunctional pumping cap for a gas condensate water collection well in view of the above-mentioned prior art, which can not only play the role of pumping water and exhausting air, but also prevent the gas condensate from overflowing.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problems is: a multifunctional pumping cap structure for a gas condensate collection well, comprising a pumping cap body, the top of the pumping cap body is covered with a pumping cover, the bottom of the pumping cap body is inserted into the pumping hole of the water collection well, and a sealing sleeve is provided between the pumping hole and the pumping cap body; an exhaust hole group is provided on the pumping cap body, and the water collection well is ventilated with the outside world through the exhaust hole group.

[0006] The outer diameter of the pumping cap body matches the pumping hole on the water collection well.

[0007] The exhaust hole group includes a plurality of exhaust holes evenly distributed in an annular direction.

[0008] A pressure ring is arranged on the outer periphery of the water extraction cap body, and the pressure ring is arranged on the top surface of the sealing sleeve.

[0009] Compared with the prior art, the advantages of the utility model are: a multifunctional pumping cap structure for a gas condensate collection well, which has a simple structure and is easy to install. It can not only pump water and exhaust air, but also prevent rainwater and garbage from entering the collection well, thereby preventing gas condensate from overflowing.

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] like Figure 1 , 2 As shown, a multifunctional pumping cap structure of a gas condensate water collection well in this embodiment includes a pumping cap body 3 of a cylindrical structure, and the outer diameter of the pumping cap body 3 matches the pumping hole on the water collection well 6. A pumping cover 1 is arranged on the top of the pumping cap body 3, and the pumping cover 1 covers the top of the pumping cap body 3, seals the top of the pumping cap body 3 and facilitates lifting the pumping cap body 3. A sealing sleeve 5 with a T-shaped cross-section is sleeved on the outer periphery of the bottom of the pumping cap body 3, and the sealing sleeve 5 is inserted into the pumping hole of the water collection well, and the edge of the sealing sleeve 5 is laid on the water collection well 6, thereby sealing the pumping hole. A plurality of circumferentially evenly distributed exhaust holes 2 are provided on the outer periphery of the pumping cap body 3, and the drain holes 2 are used to release toxic and harmful gases inside the water collection well 6, thereby ensuring the normal circulation of the gas inside the water collection well with the outside world.

[0015] A pressure ring 4 is arranged on the outer periphery of the water extraction cap body 3, and the pressure ring 4 is arranged on the top surface of the sealing sleeve 5 to prevent the sealing sleeve 5 from slipping out of the water extraction hole.

[0016] The present invention has a simple structure and is easy to install. It can not only pump water and exhaust air, but also prevent rainwater and garbage from entering the water collection well, thereby preventing gas condensate from overflowing.
