Title:
FLOW DISTRIBUTOR ASSEMBLY, VALVE BOX, AND PLUNGER PUMP
Document Type and Number:
WIPO Patent Application WO/2024/036793
Kind Code:
A1
Abstract:
A flow distributor assembly, a valve box, and a plunger pump. The flow distributor assembly comprises a flow distributor (100), a first valve body (210), a second valve body (220), a first valve rubber seal (310) and a second valve rubber seal (320), wherein the flow distributor (100) is provided with a liquid output hole (110) and a liquid intake hole (120), the liquid output hole (110) being in communication with a first end face and a second end face of the flow distributor (100) facing away from each other in the axial direction of the flow distributor itself, and the liquid intake hole (120) being in communication with a side face and the first end face of the flow distributor (100); the first valve body (210) is configured to plug the liquid intake hole (120); the second valve body (220) is configured to plug the liquid output hole (110); the first valve rubber seal (310) is configured to connect to the first valve body (210) and the first end face in a sealing manner; and the second valve rubber seal (320) is configured to seal the second valve body (220) and the second end face. The flow distributor assembly can be installed in a valve box of a plunger pump, and liquid flows in the axial direction of the flow distributor, such that an alternating cavity, a low-pressure cavity and a high-pressure cavity in the valve box can be distributed in the axial direction of the flow distributor, thereby preventing the stress concentration phenomenon during a liquid flowing process.
