In order to solve the problem existing for background technique, the utility model have employed following technological scheme: a kind of for the one-way valve in oil filed pipeline, comprise valve body, valve seat, valve ball, spring and spring capping, valve pocket is provided with in described valve body, described valve pocket two ends are respectively filler opening and oil outlet, described valve seat is fixed in described valve pocket, described valve ball is arranged on described valve seat, described spring capping is installed in one end of close oil outlet in described valve pocket and spring capping is provided with through hole, described spring be arranged at valve ball and and spring capping between, the side of described valve body is provided with the side pipe shaping with described valve body, the cleaning passage be connected with described valve pocket is provided with in described side pipe, described side pipe is provided with plug.
By adopting above-mentioned technological scheme, when valve inner is stained with more impurity effect to the normal work of one-way valve, plug on side pipe can be screwed off, then use special cleaning means to be extend in valve pocket by the flushing channel of side pipe just to clear up valve inner, thus do not need whole one-way valve to clean from oil filed pipeline dismounting, keep in repair also more convenient, will time and the manpower of cleaning and maintenance be greatly reduced, and be conducive to the manufacturing efficiency improving oil well operation.
Further setting of the present utility model: described valve seat is provided with conical-surface type through hole, described conical-surface type through hole is reduced gradually by the diameter near described valve ball one end extremely away from described valve ball one end.
By adopting above-mentioned technological scheme, the area of contact of valve ball and valve seat being increased, being conducive to increasing the sealing effect between valve ball and valve seat, flowing backwards to prevent fluid.
Further setting of the present utility model: described spring is arranged with spring seat near one end of described valve ball, the periphery wall of described spring seat and the inwall of described valve pocket are Spielpassung.
By adopting above-mentioned technological scheme, the setting of its spring seat can the path of better restraining spring, making spring can not produce the phenomenon of off normal when compressing and launch, be conducive to the raising of sealing, and spring seat and valve pocket can make more stable the flowing through of fluid by Spielpassung.
Further setting of the present utility model: one end that described spring seat is positioned at valve ball is provided with V-type groove, described valve ball presses on described V-type groove.
By adopting above-mentioned technological scheme, be provided with V-type groove by side spring seat and valve ball compressed, can the position of better fixed valve ball, make the better effects if that it seals.
Further setting of the present utility model: described plug and described side pipe are for being threaded, and the end face of described plug and described side pipe joint is provided with gasket seal.
By adopting above-mentioned technological scheme, plug and side pipe are threaded connection and the dismounting of plug can be made more convenient, and the setting of gasket seal can be good at preventing fluid from flowing out from the connection gap of plug and side pipe.
The beneficial effects of the utility model are: the utility model is by being provided with side pipe in valve body side, thus do not need it to dismantle from pipeline just can carry out internal washing, keep in repair also more convenient, time and the manpower of cleaning and maintenance will be reduced, and by being provided with conical-surface type through hole on valve seat, the sealing effect between valve ball and valve seat can be increased, to prevent fluid from flowing backwards, be conducive to the manufacturing efficiency improving oil well operation.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation for the one-way valve in oil filed pipeline of the utility model.
Embodiment
In order to make content of the present utility model more clear, below in conjunction with embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model embodiment's is a kind of for the one-way valve in oil filed pipeline, comprise valve body 1, valve seat 2, valve ball 3, spring 4 and spring capping 5, valve pocket 11 is provided with in valve body 1, valve pocket 11 two ends are respectively filler opening 12 and oil outlet 13, further, valve seat 2 is fixed in valve pocket 11, valve ball 3 is arranged on valve seat 2, spring capping 5 is installed in one end of close oil outlet 13 in valve pocket 11 and spring capping 5 is provided with through hole 51, spring 4 be arranged at valve ball 3 and and spring capping 5 between, further, the side of valve body 1 is provided with the integrated side pipe 6 with valve body 1, the cleaning passage 61 be connected with valve pocket 11 is provided with in this side pipe 6, and side pipe 6 is provided with plug 7, like this when valve body 1 viscous with more impurity effect to the normal work of one-way valve time, plug 7 on side pipe 6 can be screwed off, then use special cleaning means to be extend in valve pocket 11 by the flushing channel of side pipe 6 just to clear up valve body 1 inside, thus do not need whole one-way valve to clean from oil filed pipeline dismounting, keep in repair also more convenient, time and the manpower of cleaning and maintenance will be greatly reduced, be conducive to the manufacturing efficiency improving oil well operation.
