Abstract
The utility model relates to a kind of valve body of coupled column plug water injection pump, and described valve body is combination wear body, and described combination wear body comprises steel body and wear-resistant elements.Water injection pump valve body wear resistance provided by the utility model is good, is easy to repair and replacement, can increases substantially the working life of water injection pump.
Description
Technical field
The utility model relates to a kind of water injection pump valve body, particularly relates to a kind of plunger type water injection pump valve body, belongs to petroleum machinery and manufactures field.
Background technique
The large-scale water injection pump of current petroleum industry is due to valve body accessory serious wear wherein, often need repair and replacement, generally, water injection pump valve body just needs to change for one month, in the situation that working condition is severe, valve body uses 48 hours just to be needed to change, existing valve body is generally manufactured by forging method, produced valve body wear resistance is poor, usually can only accomplish that surface has certain wear resistance when carrying out wear-resisting property strengthening by existing heat treatment, wear resistance is uneven, valve body surface is in use caused to be uneven, affect the sealing of water injection pump, just valve body must be changed, the frequent replacing of valve body, substantially increase the consumption of valve body, cause the use and maintenance cost of water injection pump to remain high always.
Model utility content
The utility model, for the deficiencies in the prior art, provides a kind of Novel combined column plug water injection pump valve body.
The technological scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of coupled column plug water injection pump valve body, is characterized in that, described valve body is combination wear body, and described combination wear body comprises steel body and wear-resistant elements, and described wear-resistant elements comprises upper bottom surface wear-resistant elements and bottom surface wear-resistant elements.
The beneficial effects of the utility model are: water injection pump valve body wear resistance provided by the utility model is good, greatly can improve the working life of water injection pump.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described upper bottom surface wear-resistant elements and bottom surface wear-resistant elements are made up of metal or pottery.
The beneficial effect of above-mentioned further scheme is adopted to be while improving wear resistance, ensure the intensity of the pump housing.
Further, described steel body and upper bottom surface wear-resistant elements and bottom surface wear-resistant elements are by welding, riveted joint or the combination of cementing form.
