Description
Technical field
The utility model relates to oil field more particularly to a kind of check-valves for oil exploitation.
Background technique
To prevent petroleum from flowing backwards in petroleum pipeline, more setting installation check-valves on petroleum pipeline conveying circuit, however it is existing
For oil exploitation check-valves volume install position inaccurate, reduce the stability of structure between check-valves and petroleum pipeline.
Utility model content
The utility model In view of the above shortcomings of the prior art, open for petroleum by the one kind for providing a kind of accurate positioning
The check-valves adopted.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of check-valves for oil exploitation, including check-valves, mounting flange, gasket, fixing sleeve, adapter sleeve, institute
Check-valves two sides are stated with installing pipe, the installing pipe outside has mounting flange, is connected and fixed set on the outside of the mounting flange,
The fixing sleeve two sides have fixed link, and the fixed link is sequentially connected mounting flange, fixture nut, and the mounting flange is consolidated
Fixed set forms mounting flange slot, and petroleum pipeline has mounting flange, and the mounting flange and mounting flange slot are adapted, the fixation
Flange groove is connected and fixed flange, has convex grooving on the inside of the mounting flange, has convex in the middle part of the mounting flange
It rises, the positioning protrusion and convex grooving are adapted, and the convex grooving connects positioning protrusion, the convex grooving two
Side and gasket are adapted, and the convex grooving connects gasket side, and the gasket other side connects positioning protrusion, institute
It states and is adapted on the outside of fixing sleeve with adapter sleeve, the adapter sleeve is connected and fixed set, and the adapter sleeve rotates on fixing sleeve, described
It is connected through a screw thread on the inside of adapter sleeve with petroleum pipeline.
The adapter sleeve has fastening protrusion, and the fixing sleeve has fastening projecting slot, the fastening projecting slot and fastening
Protrusion is adapted, and the fastening protrusion connection fastening projecting slot, the fastening protrusion rotates in fastening projecting slot.
The utility model has the advantages that
Mounting flange is embedded in mounting flange slot, makes the connection accurate positioning of installing pipe, petroleum pipeline, fixed inner room, in turn
Stablize check-valves and petroleum pipeline opposed configuration.Gasket is separately connected convex grooving, positioning protrusion, improve installing pipe with
The leakproofness of petroleum pipeline junction, it is structurally reasonable.Fixed link is sequentially connected mounting flange, fixture nut, makes installing pipe and oil transportation
The connection structure of pipe is stablized.Petroleum pipeline is connected through a screw thread with adapter sleeve, enables the relative position of adapter sleeve and petroleum pipeline convenient for adjusting
It saves, fastening protrusion rotates in fastening projecting slot, so that the connection status of fixing sleeve and mounting flange, mounting flange is convenient for adjusting
Section, it is easy to operate, and can be improved the tightness that mounting flange slot is connect with mounting flange.This non-return for oil exploitation
Valve accurate positioning improves the stability of structure between check-valves and petroleum pipeline.
Detailed description of the invention
Fig. 1 is a kind of check valve structure schematic diagram for oil exploitation described in the utility model.
Fig. 2 is a kind of check-valves partial enlarged view for oil exploitation described in the utility model.
Specific embodiment
The utility model is described in further detail below according to drawings and examples:
A kind of check-valves for oil exploitation, including check-valves 1, mounting flange 5, gasket 9, fixing sleeve 10, fastening
Set 13,1 two sides of check-valves have installing pipe 2, have mounting flange 3 on the outside of the installing pipe 2, outside the mounting flange 3
Side is connected and fixed set 10, and 10 two sides of fixing sleeve have fixed link 11, and the fixed link 11 is sequentially connected mounting flange 3, consolidates
Determine nut 12, the mounting flange 3, fixing sleeve 10 form mounting flange slot 4, and petroleum pipeline 6 has mounting flange 5, the fixation
Flange 5 and mounting flange slot 4 are adapted, and the mounting flange slot 4 is connected and fixed flange 5, and it is fixed to have on the inside of the mounting flange 5
Position projecting slot 7 has positioning protrusion 8 in the middle part of the mounting flange 3, and the positioning protrusion 8 is adapted with convex grooving 7, institute
It states convex grooving 7 and connects positioning protrusion 8,7 two sides of convex grooving and gasket 9 are adapted, the convex grooving 7
9 side of gasket is connected, 9 other side of gasket connects positioning protrusion 8, and 10 outside of fixing sleeve and 13 phase of adapter sleeve are suitable
Answer, the adapter sleeve 13 is connected and fixed set 10, and the adapter sleeve 13 rotates on fixing sleeve 10,13 inside of the adapter sleeve with it is defeated
Oil pipe 6 is connected through a screw thread.
The adapter sleeve 13 has fastening protrusion 14, and the fixing sleeve 10 has fastening projecting slot 15, the fastening protrusion
Slot 15 and fastening protrusion 14 are adaptable, the 14 connection fastening projecting slot 15 of fastening protrusion, and the fastening protrusion 14 is convex in fastening
Rotation in grooving 15.
Mounting flange 5 is embedded in mounting flange slot 4, positions the connection between installing pipe 2, petroleum pipeline 6, fixing sleeve 10 quasi-
Really, and then stablize check-valves 1 and 6 opposed configuration of petroleum pipeline.Gasket 9 is separately connected convex grooving 7, positioning protrusion 8, mentions
The high leakproofness of installing pipe 2 and 6 junction of petroleum pipeline, it is structurally reasonable.Fixed link 11 is sequentially connected mounting flange 3, fixed spiral shell
Mother 12 stablizes installing pipe 2 and the connection structure of petroleum pipeline 6.Petroleum pipeline 6 is connected through a screw thread with adapter sleeve 13, enables adapter sleeve
13 with the relative position of petroleum pipeline 6 convenient for adjusting, fastening protrusion 14 rotates in fastening projecting slot 15, so that fixing sleeve 10 and peace
The connection status of flange 3, mounting flange 5 is filled convenient for adjusting, it is easy to operate, and can be improved mounting flange slot 4 and mounting flange 5
The tightness of connection.This check-valves accurate positioning for oil exploitation improves the steady of structure between check-valves and petroleum pipeline
It is qualitative.
