Abstract
A kind of sap cavity reducing Fracturing Pump Valve Box stress and concentrate that the utility model provides, enter structure by changing traditional sap cavity and increase the turning size that position is passed through in criss-crossing mutually, improve the intensity of criss-crossing Xiang Guan position corner, and it is concentrated to eliminate the stress passing through place mutually.Improve the radius of fillet under sap cavity inlet end water chamber, expand the sectional area that stress is concentrated, concentrate to reduce stress, eliminate the cracking caused because the place's of passing through stress mutually concentrates.Fracturing Pump Valve Box bears ultrahigh pressure, high-corrosion medium within 105MPa for a long time, improves the working life of clack box.
Description
Technical field
The utility model relates to a kind of sap cavity reducing Fracturing Pump Valve Box stress and concentrate, and belongs to fracturing work device technique field.
Background technique
Fracturing Pump Valve Box is easily worn part indispensable on fracturing unit truck, and previous Fracturing Pump Valve Box sap cavity place, passes through position fillet less mutually, and stress concentration factor is large, and crackle is easily in this germinating also secondary exhibition.
Tradition plunger pump valve case adopts cross type mostly, plunger end 1 and gland end 2 are on the same axis, sap cavity exhaust end 4 and sap cavity inlet end 5 are on the same axis and define criss-crossing perpendicular to plunger end 1 with gland end 2 intersection and pass through position 3 mutually, the rounded corners that position 3 is passed through in criss-crossing is mutually less than normal, easy generation stress is concentrated, and clack box easily ftractures.Under sap cavity inlet end 5 water chamber, fillet is less than normal, and the same stress that easily produces is concentrated, and also easily ftractures.In order to the stress reducing Fracturing Pump Valve Box sap cavity is concentrated, to this has been lasting research.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple and reasonable for structure, long service life and can reduce the sap cavity that Fracturing Pump Valve Box stress concentrates.For this problem of stress concentration, the stress having done this concentrates virtual test, and result display clack box bulk strength is inadequate.Therefore increase the fillet radius that fillet under position and water chamber is passed through in crucial sap cavity criss-crossing mutually, expand the sectional area that stress is concentrated, concentrate to reduce stress, eliminate the cracking caused because the place's of passing through stress mutually concentrates, thus improve the working life of product.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of sap cavity reducing Fracturing Pump Valve Box stress and concentrate.Comprise plunger end, gland end is coaxial with plunger end, gland end is at the right-hand member of plunger end, sap cavity exhaust end is perpendicular to plunger end, gland end and above joint, it is characterized in that: below described sap cavity exhaust end, be coaxially provided with Pear Shaped suction side sap cavity, sap cavity inlet end is coaxially in sap cavity exhaust end, form criss-crossing and pass through position mutually, under described gland end, fillet radius is 15mm ~ 30mm, under plunger end, fillet radius is 15mm ~ 30mm, plunger end and sap cavity exhaust end intersection area are 15 × 45 ° and rounding off radius is 7mm ~ 10mm, gland end and sap cavity exhaust end intersection area are 15 × 45 ° and rounding off radius is 7mm ~ 10mm.
Preferably, described sap cavity inlet end water chamber gradient is 15 ° ~ 20 °.
Preferably, under described sap cavity inlet end water chamber, the radius of fillet is 10mm ~ 20mm.
What the utility model provided a kind ofly reduces the sap cavity that Fracturing Pump Valve Box stress concentrates and enters structure by changing traditional sap cavity and increase the turning size that position is passed through in criss-crossing mutually, improve the intensity of criss-crossing Xiang Guan position corner, and it is concentrated to eliminate the stress passing through place mutually.Improve the radius of fillet under sap cavity inlet end water chamber, ultrahigh pressure, high-corrosion medium within making Fracturing Pump Valve Box bear 105MPa for a long time, improve the working life of clack box.
