Embodiment 1

[0022] An adaptive eccentric load combined valve plate for plunger pumps. Such as figure 1 As shown, the valve plate is formed by embedding the first valve plate 1 and the second valve plate 3 . A sealing ring 2 is installed between the first distribution disc 1 and the second distribution disc 3, and the first distribution disc 1 and the second distribution disc 3 are discs with equal diameters.

[0023] Such as figure 1 As shown, the distribution plate is provided with a central through hole 5, an oil suction window 4 is provided on one side of the central through hole 5, and an oil pressure window 6 is provided on the other side of the central through hole 5, and the oil suction window 4 and the oil pressure window 6 are symmetrically arranged , The oil suction window 4 and the oil pressure window 6 are both "C" shaped through holes.

[0024] Such as figure 2 As shown, the inner surface of the first distribution disc 1 is evenly provided with bosses 7 , and the bosses ...

Embodiment 2

[0029] An adaptive eccentric load combined valve plate for plunger pumps. Except following technical parameter, all the other are with embodiment 1:

[0030] The height of the boss 7 is 12-20mm, the depth of the groove 9 is the same as the height of the boss 7, and the inner wall of the groove 9 is the same shape as the outer wall of the boss 7.

[0031] The number of said bosses 7 is 3-8, and the number of bosses 7 and grooves 9 is the same.

[0032] Compared with the prior art, this specific embodiment has the following advantages:

[0033] 1. This specific embodiment is composed of the first distribution disc 1 and the second distribution disc 3. The material of the first distribution disc 1 is polytetrafluoroethylene, which has a small friction coefficient, good lubricating performance, and is cheap and light. When the surface of the first distribution disc 1 is severely worn, it is not necessary to replace the entire distribution disc, only the first distribution disc 1...

Abstract

The invention relates to a self-adaptive unbalance loading combined type valve plate for a plunger pump. According to the technical scheme, the valve plate is formed by nesting a first valve plate sheet (1) and a second valve plate sheet (3), a seal ring (2) is installed between the first valve plate sheet (1) and the second valve plate sheet (3), and the first valve plate sheet (1) and the second valve plate sheet (3) are circulate disks with equal diameters. A center through hole (5) is formed in the valve plate, an oil suction window (4) is formed in one side of the center through hole (5), an oil pressing window (6) is formed in the other side of the center through hole (5), and the oil suction window (4) and the oil pressing window (6) are both C-shaped through holes. The inner side face of the first valve plate sheet (1) is evenly provided with convex plates (7), and the convex plates (7) are located on the edge of the first valve plate sheet (1). Grooves (9) are correspondingly formed in the inner side face of the second valve plate sheet (3), and the convex plates (7) and the grooves (9) are mutually nested; an annular sealing groove (8) is formed in the inner side face of the second valve plate sheet (3). The self-adaptive unbalance loading combined type valve plate for the plunger pump has the advantage that the cost is low, the machining is simple, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of a plunger pump distribution plate. In particular, it relates to an self-adaptive eccentric load combined valve plate for a plunger pump. Background technique [0002] With the development and progress of science and technology, the plunger pump is developing towards high pressure, high speed and large flow. As one of the most important hydraulic components, the plunger pump is widely used in metallurgical equipment, engineering machinery, machine tools and aerospace and other fields. Therefore, higher requirements are put forward for the working performance and service life of the plunger pump. The valve plate is one of the important parts in the plunger pump. Improving the characteristics of the valve plate is of great significance to improve the performance and life of the plunger pump. "An alloy steel material for a flow plate for a plunger pump and its preparation method" (201210109994.1) patent tec...
