Abstract
A kind of containing valve seat integral type valve bonnet, comprise the valve seat that valve bonnet and its inside are provided with, the formula structure and described valve bonnet and valve seat are processed as one.The utility model changes the structure of valve bonnet and valve seat, original two component (valve bonnet and valve seat) overall processing is become parts, save pipe close, avoid original three component separately to cause causing valve seat pipe close sealing surface that the problem of thorn leakage occurs, effectively improve the working life of oil well pump.
Description
Technical field
The utility model belongs to field of petroleum machinery, is specially a kind of oil pump with containing valve seat integral type valve bonnet.
Background technique
In existing oil well pump, the lower end of valve bonnet is provided with valve seat, and because valve bonnet and valve seat are independently parts, therefore valve seat needs to support fixing by the pipe close of bottom; But in use, because valve bonnet, valve seat, pipe close are three component independently separated, assemble successively during use, split type structure easily causes valve seat pipe close sealing surface that the problem of thorn leakage occurs.
Model utility content
The purpose of this utility model is exactly poorly sealed for prior art sealing surface of seat, causes sealing surface problem, provide that a kind of structure is simple, easy to operate, good sealing effect and long service life containing valve seat integral type valve bonnet.
The concrete technological scheme of the utility model is: comprise the valve seat that valve bonnet and its inside are provided with, the formula structure and described valve bonnet and valve seat are processed as one.
The utility model changes the structure of valve bonnet and valve seat, original two component (valve bonnet and valve seat) overall processing is become parts, save pipe close, avoid original three component separately to cause causing valve seat pipe close sealing surface that the problem of thorn leakage occurs, effectively improve the working life of oil well pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the using state schematic diagram after the utility model upset;
In figure: 1, valve bonnet, 2, valve seat, 3, valve ball, 4, plunger connector.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, a kind of containing valve seat integral type valve bonnet, comprise the valve seat 2 that valve bonnet 1 and its inside are provided with, the formula structure and described valve bonnet 1 and valve seat 2 are processed as one; During use, valve seat 2 is installed valve ball 3, valve bonnet 1 upper end connects plunger connector 4(for connecting plunger).
The utility model is poorly sealed for sealing surface of seat exactly and cause sealing surface problem, and to valve bonnet reform, valve seat and valve bonnet are processed into integral structure, ensure that usability, avoiding valve seat thorn leaks, and improves the working life of oil well pump.To improve the working life of oil well pump, cost-saving.
For those skilled in the art, under the prerequisite not departing from the utility model principle, likely make some improvements and modifications to partial structurtes, these improvements and modifications also should be considered as protection domain of the present utility model.
