Abstract
The utility model discloses a kind of gasket type one-way valve, it comprises valve body, valve gap, rotating shaft, sealing surface, valve handle, valve body is the sheet cylindrical body, the heart is processed with conical surface hole therein, perpendicular to being processed with small sircle hole on the cylinder axis direction, in this circular hole rotating shaft is installed at an upper portion thereof, valve gap top and rotating shaft link, valve gap is the outer conical surface thin slice, and the conical surface hole of the outer conical surface of valve gap and valve body forms sealing surface.Valve gap can freely be opened in valve body around rotating shaft like this, and when pipeline had the fluid of certain pressure to flow through, one-way valve was in opening state, and it can be closed automatically when unexpected cutout, prevents a large amount of refluences of tube fluid effectively.The utility model modern design, reflection is sensitive, crushing is little, can realize efficient good sealing to leak source.
Description
Technical field the utility model relates to a kind of pipe fittings of the enterprise's crude oil production of recovering the oil.
Background technique gasket type one-way valve is the important accessory that guarantees oil well ordinary production, crude oil transmission.At present, the one-way valve of various different structures is being used at the scene, these one-way valves are under the prerequisite that guarantees oil well ordinary production, crude oil transmission, have different characteristics and function separately, such as angie type valve ball, clamp band type boatswain chair, flange-type valve block etc., but still have to some extent that sealability is not ideal enough, deficiency such as installation check, repair and replacement workload are bigger, particularly cause the refluence of gathering line crude oil to leak because sealing is bad, cause site environment to pollute and the crude oil loss, influence the oil well ordinary production simultaneously.
The summary of the invention the purpose of this utility model is to provide a kind of installation, inspection, repair and replacement extremely convenient, and the gasket type one-way valve of good seal performance causes the technical problem that liquid flows backwards in the gathering line to solve the upstream line flow process because of perforation, fracture, reason such as run-down.The utility model is achieved in that this kind gasket type one-way valve, and it comprises valve body, valve gap, rotating shaft.Valve body is the sheet cylindrical body, the center is processed with conical surface hole, at an upper portion thereof near having small sircle hole on the conical surface and the direction perpendicular to cylinder axis, in this circular hole rotating shaft is installed, rotating shaft and valve gap link, and valve gap is the outer conical surface thin slice, and the conical surface hole of the outer conical surface of valve gap and valve body forms conical surface seal, valve gap can rotate around the shaft, and just falls into the conical surface hole realization sealing of valve body.The hollow cylinder surface of valve body is a sealing surface.The utility model is used for mesolow oil (water) pipeline of different size, is installed between pipeline flange and the gate flanged surface or between pipeline two flanges, sealing surface adds the asbestos rubber cushion, and the valve gap opening direction is a liquid flow direction.When upstream perforation, fracture, when run-down, valve gap is closed by the thrust of deadweight and fluid refluence, prevents that liquid in pipe from flowing backwards in a large number.The utility model is compared with the one-way valve of other type, has the following advantages: modern design, and rational in infrastructure, utilize it to realize efficient good sealing to leakage point, guarantee the oil well ordinary production, avoid waste and pollute; Installation need not be moved electrogas welding, checks and changes conveniently; Volume is little in light weight, and reflection is sensitive, and crushing is little.
Description of drawings Fig. 1 is a generalized section of the present utility model.Among the figure: 1 valve body; 2 rotating shafts, 3 valve gaps
Embodiment is with reference to accompanying drawing 1, and the utility model is made up of valve body 1, valve gap 2, rotating shaft 3 etc.Valve body 1 is the sheet cylindrical body, the center is processed with the hole of conical surface, being processed with small sircle hole on perpendicular to cylindrical direction near the upper end in this hole, rotating shaft 2 is installed on this circular hole, valve gap 3 is connected in this rotating shaft, valve gap is the thin slice that is processed with conical surface, this conical surface is corresponding with the conical surface hole of valve body 1, and forms conical surface seal, and valve gap 3 can freely rotate around rotating shaft is upper and lower, upper end at valve body 1 is processed with valve handle, is used for the upper and lower location of valve.The upper and lower surface of the hollow cylinder of valve body is a sealing surface, and valve body 1 and valve gap 2 link to each other by rotating shaft like this, and valve gap 3 and valve body 1 are by conical surface seal, sealing surface and the pressured tightening seal of asbestos rubber cushion.When installing and using, valve body 1 place between the pipeline flange or gate flange and pipeline flange between, with the sealing of asbestos rubber cushions, use Bolt Connection between flange and the valve body 1, valve body is located by adjusting valve handle.
