Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] Such as figure 1 As shown, the shale oil and gas hydraulic fracturing Y-shaped hydraulic end of the present invention is mainly composed of the following parts: Y-shaped hydraulic end valve box 1, the first centerline 2, the second centerline 4, and the third centerline 3 , discharge valve seat 5, discharge valve 6, discharge spring centralizer 7, discharge plug 8, discharge pressure cap 9, suction valve 10, suction valve seat 11, suction spring centralizer 12, low pressure sand bag 13, Low-pressure liquid inlet 14, high-pressure outlet 15, plunger 16, plunger connection plate 17, discharge valve hole 18, suction valve hole 19, plunger hole 20 are formed.
[0026] Such as figure 2 As shown, the Y-shaped fluid end valve box is formed by a discharge valve hole 18, a suction valve hole 19 and a plunger hole 20 to form a Y-shaped inner cavity.
[0027] Each Y-sh...
