Abstract
The utility model relates to a petroleum pumping unit technical field, in particular to valve bonnet on plunger of increase strength. The device includes top connection and valve bonnet, and the top connection is connected in the valve bonnet upper end, and the inside cavity that can adorn the valve ball that is equipped with of valve bonnet is equipped with the ball blocking piece spacing to the valve ball in the through-hole of valve bonnet upper end, is the oil passage between ball blocking piece and the valve bonnet upper end inner wall, and the inside cavity of valve bonnet communicates with each other through passing oil passage and top connection is inside, and it has a plurality of oil-outs to open on the top connection lateral wall. The utility model discloses an increase valve bonnet intensity on the plunger, prevent that the valve bonnet from taking place to break off on the plunger. The defects that the upper valve cover of the existing oil well pump small plunger is low in strength and a connecting rib between oil outlets of the upper valve cover is easy to break off are overcome.
Description
The technical field is as follows:
the utility model relates to a petroleum pumping unit technical field, in particular to valve bonnet on plunger of increase strength.
The background art comprises the following steps:
at present, because a small plunger of an oil well pump is limited by the size of the oil well pump, the pipe wall of a valve cover on the plunger is thin, four oil outlets are formed in the circumference of the side wall of the valve cover on the plunger, and a connecting rib is arranged between every two adjacent oil outlets.
The utility model has the following contents:
the to-be-solved technical problem of the utility model is to provide a valve bonnet on plunger of gaining in strength, the device has realized increasing valve bonnet intensity on the plunger, prevents that the valve bonnet from taking place to take off absolutely on the plunger. The defects that the upper valve cover of the existing oil well pump small plunger is low in strength and a connecting rib between oil outlets of the upper valve cover is easy to break off are overcome.
The utility model adopts the technical proposal that: the utility model provides a valve bonnet on plunger of gaining in strength, includes top connection and valve bonnet, and the top connection is connected in the valve bonnet upper end, and the inside cavity that can adorn the valve ball that is equipped with of valve bonnet is equipped with the ball blocking piece spacing to the valve ball in the through-hole of valve bonnet upper end, is the oil passage between ball blocking piece and the valve bonnet upper end inner wall, and the inside cavity of valve bonnet communicates with each other through oil passage and top connection is inside, and it has a plurality of oil-outs to open on the top connection lateral wall.
Further, the upper connector is in threaded connection with the valve cover.
The utility model has the advantages that: the invention adopts the structure that the upper joint is connected with the valve bonnet, the valve ball is placed in the valve bonnet, the side wall of the valve bonnet is not provided with the oil outlet, the space is large, the abrasion of the valve ball to the wall thickness of the valve bonnet is small, the side wall of the upper joint is provided with the oil outlet, the valve ball is not placed in the upper joint, the rib column between the oil outlets of the upper joint can be thickened, meanwhile, the abrasion of the valve ball is not required to be born, the strength of the valve bonnet on the plunger is increased, and the valve bonnet on the plunger is prevented from breaking.
Description of the drawings:
the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
as shown in figure 1, valve casing on plunger of increase strength, including top connection 1 and valve casing 2, top connection 1 threaded connection is in valve casing 2 upper ends, the inside cavity that can adorn the valve ball that is equipped with of valve casing 2, be equipped with in the through-hole of valve casing 2 upper ends to spacing ball retainer 4 of valve ball, be the oil passing channel between ball retainer 4 and the valve casing 2 upper end inner wall, the inside cavity of valve casing 2 communicates with each other through oil passing channel and top connection 1 is inside, it has a plurality of oil-outs 3 to open on the top connection 1 lateral wall.
When the valve is used, the valve ball moves in the valve cover 2, so that the ribs between the oil outlets of the upper joint 1 cannot be abraded, and the ribs are prevented from breaking off.
It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
