Description

A kind of buffer structure device for spiral oscillating motor
Technical field
The utility model belongs to hydraulicvalve technical field, is specifically related in a kind of buffer structure device for spiral oscillating motor.
Background technology
Although there has been cushion valve or the mechanical cushioning device of many kinds market now, but really can apply to the snubber assembly above spiral oscillating motor almost not have, it is that installation mode and spiral oscillating motor do not meet, shock-absorbing capacity is good not, it is that sealing property is good not, the shock problem of spiral oscillating motor stroke terminal cannot be solved.
The utility model has been studied for the problems referred to above, it is intended to finds one to gather very easily and reaches good shock-absorbing capacity above spiral oscillating motor cylinder body, solves the scheme of spiral oscillating motor at the shock problem of stroke terminal.
Practical novel content
For above-mentioned problems of the prior art, the utility model provides a kind of buffer structure device for spiral oscillating motor.
The technical solution of the utility model is as follows:
For a buffer structure device for spiral oscillating motor, comprise spool, valve pocket and valve body; Described valve body is provided with medium through hole, return port and valve opening, and described medium through hole is vertical with valve opening and crossing with described return port; Described valve opening is provided with ledge structure, and its aperture increases from inside to outside successively, and described spool is arranged in valve opening, is provided with a through hole in the middle of spool; Described valve pocket one end is located in valve opening, and the other end is fixed on valve body, and one end that described valve pocket is located in valve opening is provided with groove, is provided with spring in groove, and spring is by compressing a steel ball and blocked by the through hole of described spool and is pressed on the ledge structure of valve opening by spool.
A preferred version of the present utility model is: described spool adopts taper structure, and tapering is less than 45 ��, to reduce the vibrations that the power of surging is brought.
A preferred version of the present utility model is: described valve pocket is provided with sealing-ring groove, for placing O to increase sealing intensity.
The buffer structure device of employing said structure can be gathered above spiral oscillating motor cylinder body easily and play good shock-absorbing capacity.
Accompanying drawing explanation
Fig. 1 is longitudinal diagrammatic cross-section of the buffer structure device for spiral oscillating motor of the present utility model.
Fig. 2 is the horizontal section schematic diagram of the buffer structure device for spiral oscillating motor of the present utility model.
Embodiment
The better embodiment of the utility model is provided, so that the technical solution of the utility model to be described in detail below in conjunction with accompanying drawing.
The buffer structure device for spiral oscillating motor of the present utility model as depicted in figs. 1 and 2, comprises spool 100, valve pocket 200 and valve body 300; It is vertical with valve opening and crossing that valve body 300 is provided with medium through hole 301, return port 302 and valve opening 303, medium through hole and return port; Valve opening is provided with ledge structure, and its aperture increases from inside to outside successively, and spool is arranged in valve opening, is provided with a through hole 101 in the middle of spool; Valve pocket one end is located in valve opening, the other end is fixed on valve body by bolt 201, one end that valve pocket is located in valve opening is provided with groove 202, is provided with spring 203 in groove, and spring is by compressing a steel ball 204 and blocked by the through hole 101 of spool and is pressed on the ledge structure of valve opening by spool.
Spool adopts taper structure, and tapering is less than 45 ��, to reduce the vibrations that the power of surging is brought.
Valve pocket is provided with sealing-ring groove 205, for placing O 206 to increase sealing intensity.
During work, device of the present utility model is installed on spiral oscillating motor, the liquid medium passage of hydro-cylinder is communicated, Piston Compression medium liquid (Fig. 1 arrow show piston motion direction) so that it is enter in medium through hole with medium through hole and return port. When pressure reaches to a certain degree, the pressure of medium liquid compression spool is greater than spring to the pressure of steel ball, spool moves thus by medium through hole and return port UNICOM (Fig. 2), causes medium liquid to reflux, thus reduces medium liquid to the impact of device.
More than show and describe ultimate principle of the present utility model, main characteristic sum advantage of the present utility model. The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
