Description

Fracturing pump valve box adopting Y-shaped spring positioner
Technical Field
The utility model relates to a fracturing pump technical field, more specifically relate to an adopt fracturing pump valve box of Y type spring location ware. Background
The fracturing pump valve box is a key part of the fracturing pump, the fracturing pump valve box mainly comprises a suction valve, a suction cavity, a plunger, a discharge cavity, a discharge valve and a valve box body, the power end of the fracturing pump drives the plunger to do reciprocating linear motion, and the suction circulation work of sucking and discharging fracturing fluid is realized in a hydraulic end through the alternate opening and closing motion of the suction valve and the discharge valve, so that the fracturing pump can finally inject the fracturing fluid into a well in a high-pressure fluid energy mode to perform fracturing operation. Whether the fracturing pump valve box can work reliably and stably has a direct relation with whether the suction valve works well, if the suction valve works unstably and has poor durability, the hydraulic end is directly led to the abnormity of the suction and the discharge of the fracturing fluid, the large fluctuation of the flow and the pressure is led to, and even the whole fracturing pump valve box vibrates seriously because of a serious empty pump (the suction fluid is insufficient), so that the safety of equipment and the fracturing operation construction are influenced. The spring positioner of the suction valve needs to be specially pre-tightened and positioned so as to ensure that the spring can provide proper spring restoring force at a specified working position, so that the suction valve can normally open and close to work circularly, meanwhile, the spring positioner of the suction valve occupies a critical position in the fracturing pump valve box and is just positioned at a cross intersection part of a horizontal hole (a horizontal mounting hole, a plunger through hole) and a vertical hole (a suction valve working hole, a discharge valve working hole and a fluid overflowing flow channel hole), and the structural design of the inner cavity of the suction valve adopted at the spring positioner can greatly influence the structural strength, the hydrodynamic erosion effect and the maintenance convenience of the fracturing pump valve box, and the strength optimization and the strength improvement of the inner cavity structures of the spring positioner and the valve box suction valve and the improvement of the fluid effect are key technical innovation directions of fracturing pump valve box manufacturing enterprises.

② T-type and E-type suction valve spring locators are assembled in a groove machined on a valve box body after rotating 90 degrees (the T-type and the same), and are provided with an anti-rotation limiting eccentric groove to prevent the locators from rotating and losing positions and separating from the groove in work, but the groove matched with the locator on the valve box body has larger stress concentration parts (such as an intersecting edge of a direct contact plane, a chip cutting mark at the root of the groove, a lower end head part of an anti-rotation eccentric groove and the like) due to structural characteristics, and the stress concentration parts are difficult to be eliminated better in a grinding and shot blasting manner, so that fatigue crack grade damage generated at the groove position is induced to a certain probability in actual work, although the main fatigue crack grade source of the valve box is also at the intersecting line part of a horizontal hole and a vertical hole, but the stress concentration parts of the E-type and T-type locator compact matching grooves still have technical need to overcome the technical influence on the working life of the valve box, and particularly have the requirements on higher working strength of severe working of the high pressure and high pressure discharge of the valve box along with the development of shale gas and oil.
