Description

Valve spring seat assembly and disassembly tools

Technical Field

The utility model belongs to oil gas exploitation equipment manufacturing field, concretely relates to valve spring holder assembly and disassembly tools.

Background

The valve body is used as a one-way valve and is a core component of the oil-gas fracturing plunger pump, and the valve body is short in service time due to the fact that the valve body is in poor working conditions and bears high-pressure alternating load and high-speed fluid scouring for a long time. The service life of the prior valve body used under the pressure of 70MP and above is 12-30 hours, and the short service life of the valve body is mainly caused by frequent impact and abrasion between the valve body supporting conical surface and the valve seat conical surface, so that the valve body supporting conical surface has metal peeling, abrasion pits and the like, and finally cannot be used continuously due to sealing failure. The valve body sealing failure needs to be immediately stopped, otherwise, the valve box and the valve seat can be damaged, so that not only can serious consequences be caused, but also the progress and the efficiency of the stimulation fracturing operation are influenced, and the operation cost is increased. Meanwhile, as the fracturing operation scale is larger and larger, the continuous operation time is longer and longer, and higher requirements are provided for the service life of the easily damaged part. The valve spring seat in the valve box is a main part for supporting and assembling the valve body, and the valve spring seat needs to be disassembled and assembled when the valve body is replaced, so that whether the valve spring seat can be quickly disassembled and assembled is one of main reasons for limiting the production efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Unless specifically stated otherwise, the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
