Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1:

as shown in fig. 1 and 2, an oil valve body of an energy accumulator comprises a valve body 1 and a valve core 2, wherein an oil inlet hole 3, a mounting hole 4, an oil cavity 5 and an oil outlet hole 6 are sequentially arranged from one end to the other end of the valve body 1, and the diameters of the oil inlet hole 3, the mounting hole 4, the oil cavity 5 and the oil outlet hole 6 are sequentially reduced so as to process four holes.

As shown in fig. 2, 3 and 4, the valve core 2 is disposed in the mounting hole 4, wherein a main hole 21 axially penetrates through the center of the valve core 2, and a plurality of branch holes 22 are uniformly distributed around the valve core to ensure that the oil flowing through the oil inlet hole 3 can flow into the oil chamber 5 along the main hole 21 and the branch holes 22.

As shown in fig. 2, the oil outlet 6 is disposed in a flaring shape from one end to the other end near the oil chamber 5, so as to control the oil passing amount of the oil liquid during use and improve the control precision of the oil valve body. Simultaneously, the port position of the oil outlet hole 6 is provided with the inserting hole 7 in an expanding shape, so that the stable and accurate connection of the oil outlet hole 6 is facilitated, and the connection process of the oil valve body and the joint is more convenient.

As shown in fig. 2, the valve core 2 is screwed into the mounting hole 4, that is, the valve body 1 and the valve core 2 can be produced and processed separately, and after processing, the valve body 1 and the valve core 2 can be mounted and fixed quickly only by screwing.

The advantage of this kind of design is, in the processing of oil outlet 6, can be according to actual need, that is to say the aperture size of joint, process the aperture of oil outlet 6 wantonly to satisfy and be connected with the joint, and no matter how process, can not cause the influence to the oil valve body.

As shown in fig. 2, the connecting position of the oil chamber 5 and the oil outlet 6 is provided with an inclined chamfer with an angle of 120 °. Because fluid flows towards 6 directions of oil outlet, so set up oblique chamfer at the hookup location of oil pocket 5 and oil outlet 6, can lead and cushion fluid, avoid fluid direct impact and the phenomenon of stress concentration appears, so reduction fluid that can be fine is to the pressure and the impact force of 1 inner wall of valve body, guarantees valve body 1's life.

As shown in fig. 2, an annular tool withdrawal groove 8 is formed at a connection position of the oil cavity 5 and the mounting hole 4 to meet a tool withdrawal requirement during tool machining, so that the machining process of the valve body 1 is easier and more convenient.

As shown in fig. 2, 3 and 4, the outer wall of the valve core 2 is provided with a first half-hole 23, the inner wall of the mounting hole 4 is provided with a second half-hole 41, the first half-hole 23 and the second half-hole 41 are fastened with each other to form a circular hole with a circular cross section, and the circular hole is connected with a threaded nail (not shown in the figure) through an internal thread.

Because the valve core 2 is in operation, the axial direction can be acted with force, and because of the threaded connection, the valve core can not be ensured to be stably fixed in the valve body 1 all the time, and the axial direction movement is inevitable. So fix valve core 2 through setting up the peg to screw, the effectual axial direction's that prevents to appear behind the long-time work of valve core 2 drunkenness to improve oil valve body's stability in use.

Example 2:

as shown in fig. 5, an oil valve body of an accumulator is different from embodiment 1 in that: the oil cavity 5 is arranged in a necking shape, and the aperture of the necking position is the same as that of the oil outlet 6. Because fluid flows towards 6 directions of oil outlet, so set up oil pocket 5 to the throat form, can lead to and cushion fluid, avoid fluid direct impact and the phenomenon of stress concentration appears, so the life of reduction fluid to the pressure and the impact force of 1 inner wall of valve body 1 that can be fine guarantees.

The specific embodiments are only for explaining the present invention, and it is not intended to limit the present invention, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the present invention.
