Abstract
The utility model relates to a slurry pump fitting device for petroleum drilling, in particular to a valve box assembly for a high-pressure slurry pump. The valve box assembly comprises a plurality of transversely connected slurry pump valve boxes, wherein each slurry pump valve box mainly comprises a valve box main body, a valve cover pressure barrel and a valve seat assembly; each valve box main body comprises a suction valve box main body and a discharging valve box main body, which are arranged in parallel; a suction inlet is formed in the bottom end of each suction valve box main body; each discharging valve box main body is provided with a discharging pipe; the discharging pipes are connected through flange sleeves. The device has the advantages that each valve box main body is an independent structure, and if the valve box main bodies fail, and cannot be maintained, only the split valve box main bodies are required to be independently replaced, so that the cost is lowered; the discharging pipes are connected through the flange sleeves, only failing parts are required to be disassembled and overhauled, and the device is convenient to assemble and disassemble.
Description
Technical field
The utility model relates to a kind of oil drilling slurry pump accessory device, specifically, relates to a kind of clack box assembly for high pressure slurry pump.
Background technique
At present, oil drilling is with in slurry pump accessory, and clack box is one of crucial component, and its structure forms, and directly affects the service condition of slurry pump.The structure of conventional mud pump valve box is generally three clack box arranged in series, and suction valve box main body and the expulsion valve box main body of clack box main body are upper and lower arranging structure, the discharge tube of each clack box main body is as a whole, indivisible, dismounting inconvenience, in using process, once clack box breaks down, need suction valve box main body and expulsion valve box main body to carry out integral body maintenance, labor intensity is large, if and suction valve box main body or expulsion valve box main body wherein have fault to keep in repair, whole clack box totally will be scrapped, very inconvenient.
Model utility content
The purpose of this utility model is the shortcoming and defect for prior art, and a kind of clack box assembly of high pressure slurry pump of simple in structure and easy accessibility is provided.
The technical solution of the utility model is: a kind of mud pump valve box assembly, the mud pump valve box that comprises a plurality of horizontal connections, it is characterized in that: described mud pump valve box is mainly comprised of clack box main body, valve gap pressure cylinder and valve seat assembly, described clack box main body comprises and to suction valve box main body and the expulsion valve box main body arranged, described suction valve box main body bottom is provided with suction port, described expulsion valve box main body is provided with discharge tube, and each discharge tube overlaps connection by flange.
Preferably, described valve seat assembly comprises discharge clack box valve seat assembly and sucks clack box valve seat assembly.
Preferably, described valve gap pressure cylinder is located at valve seat assembly upper end, comprises and discharges clack box valve gap pressure cylinder and suck clack box valve gap pressure cylinder.
Preferably, described mud pump valve box is 3.
The utility model beneficial effect is compared with prior art:
(1) clack box main body comprises and to suction valve box main body and the expulsion valve box main body arranged, suction valve box main body and expulsion valve box main body design for absolute construction, as clack box main body breaks down, cannot keep in repair, only need to change separately suction valve box main body or the expulsion valve box main body of split, cost-saving.
(2) discharge tube of each expulsion valve box main body of mud pump valve box overlaps connection by flange, once suction valve box main body or expulsion valve box main body break down, only need carry out field-strip at fault place, need not dismantle complete machine, time saving and energy saving, easy accessibility.
Accompanying drawing explanation
