Abstract
The utility model discloses a locking mechanism for a fluid end valve box packing box. The locking mechanism comprises a packing box and is characterized in that a brake block is arranged above the packing box, the brake block is fixed on a fluid end valve box, a rack is arranged at the lower portion of the brake block, an outer toothed ring is positioned on the packing box, the brake block is meshed with the packing box on a contact face through the outer toothed ring and the rack, and the brake block is fixed on the fluid end vale box through a bolt. The locking mechanism has the advantages of guaranteeing reliable locking of the packing box at any position and being simple in structure.
Description
Technical field
The utility model relates to a kind of oil field operation and uses fluid end, relates in particular to a kind of retaining mechanism of fluid end clack box packing box.
Background technology
In the prior art, owing to there is not locking function, in operation process, it is loosening packing box to occur through regular meeting, causes the highly pressurised liquid seepage in the fluid end, produces bigger potential safety hazard with fluid end clack box packing box for oil field operation.Whether the maintenance personal wants the running check packing box to become flexible and in time adjusts, and has caused bigger trouble to use like this, has not only increased workload, and has reduced operating efficiency.
Summary of the invention
The utility model is to the deficiency of prior art, and a kind of retaining mechanism of simple in structure, safe and reliable fluid end clack box packing box is provided.With the loosening easily problem of thorough solution fluid end clack box packing box.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of retaining mechanism of fluid end clack box packing box; Comprise packing box, it is characterized in that the top of said packing box is provided with brake block; Said brake block is fixed on the said fluid end clack box; The bottom of said brake block is provided with tooth bar, and said packing box is provided with external toothing, and said brake block and packing box are meshing with each other through said external toothing and tooth bar on contact surface.
The beneficial effect of the utility model is: because brake block is set on packing box, and both is meshing with each other, can guarantees that packing box can both reliably lock at an arbitrary position, and also simple in structure.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said brake block is through being bolted on the said fluid end clack box.
Adopt the beneficial effect of above-mentioned further scheme to be, make brake block fixed through bolt, convenient disassembly.
Further, the profile of tooth of said tooth bar and external toothing is a triangle.
Adopt the beneficial effect of above-mentioned further scheme to be, the advantage of lance tooth is that coupling mechanism force is big, and tooth pitch is little, has also guaranteed all engageable at an arbitrary position locking of packing box.
